Int.Class B02C 13/13 Appl.No 248150 Applicant BABCOCK & WILCOX LTD Inventor

668,775. Hammer-mills. BABCOCK & WILCOX, Ltd. Jan. 31, 1950 [April 28, 1949], No. 2481/50. Class 59 In a pulverizing mill comprising classifying means arranged to receive gas-borne particles and to deliver oversize particles to a milling zone fan means are arranged to effect the flow of two streams of gaseous fluid, one of which is arranged to pass to a classifier together with material delivered by a feeder and the second of which is adapted to carry from a milling zone material delivered to that zone by the classifier. As shown, Fig. 1, fuel from feeder 1 is introduced into a preliminary milling zone comprising beaters 3 by a stream of hot gaseous fluid which issues from a duct 5 and is induced by a fan 9 the stream then carrying the particles of pulverization to a classifier 12. The classifier comprises an impact core 13 and whirl chamber 14, the fine material leaving through outlet sleeve '16,. whilst oversized particles discharged from the classifier enter the fine milling zone defined by the beaters 6 via a shoot 18 and duct 19. Pulverized material from the zone of action of the beaters 6 is carried to the classifier by a second stream of hot gaseous fluid which issues from a duct 8 and is also induced by the fan 9. It will be seen that the milling zones are arranged in parallel as regards the flow of gaseous fluid and in series as regards the flow of fuel to be milled. A centrifugal tramp iron separator is associated with the beaters 3, the renewable heads of which are of softer material than the hardened metal forming the renewable heads of beaters 6. The fan 9 may be provided with vanes such that the two gas streams may flow at different rates which are separately controlled by external means. The temperature of the two streams may also be separately controllable, the temperature of that from duct 5 being generally higher than that from duct 8. In a modification, the preliminary milling zone and associated beaters 3 are omitted the fuel being blown directly from the feeder to the classifier.

Int.Class F25D 23/02 Appl.No 2487649 Applicant ELECTROLUX LTD Inventor

669,142. Refrigerators. ELECTROLUX, Ltd. Sept. 28, 1949 [Oct. 28, 1948], No. 24876/49. Class 29. The inner linings 11, 14 of the refrigerator 10 and its door 13 are supported from the outer shells 10, 15 by plate members 38, 39, and 27, 28 respectively, which are joined by spacing means 40, 29 along one edge only, thus providing an elongated path of flow for heat transmission, and thin masking strips 44, 34 free from the weight of the inner lining are arranged along the edges of the shells for sealing the insulating space. The outer shell 10 has a surrounding supporting frame 12 carrying the door hinges 18 and supporting a wooden frame 36 to which the plate 38 is fixed by glue or by nails 62. At its other edge the plate 38 is fixed to the plate 39 by spaced wood blocks 40. The other edge of the plate 39 is fixed by spaced wood blocks 42 to a plate 46 with a fastening member 47 secured by clamping sleeves 49 to the inner shell 11, with the interposition of a rubber sealing strip 50. The plates 38, 39 are of insulating material such as " Masonite" (Registered Trade Mark), wood or synthetic resin and the space between them is filled with insulating material such as glass wool. retained by the thin sealing strip 44 of pegamoid, rubber or plastic which may be bowed outwardly. Holes 58 in the plates reduce the conductivity. The door 13 is similarly constructed, the insulating plates 27, 28 being secured together at one end by wood blocks 29 and at the other end to the outer shell 15 by wood blocks 26 and to the inner lining 14 by wood blocks 31. A similar connection is made at the apparatus window. The insulating plates have reflecting coatings of aluminium foil to minimise radiation losses, these may be divided into long slightly spaced strips to reduce heat conduction.

7.669308Improvements in or relating to damping devices for governors of hydraulic apparatus or systems

GB - 02.04.1952

Int.Class G05D 13/06 Appl.No 1414948 Applicant OLAER MARINE Inventor

669,308. Fluid-actuated valves with dashpots. MARINE, O. May 25, 1948 [June 28, 1947], No. 14149/48. Class 135 [Also in Groups XXVIII and XXXII] A valve comprises a closure member 20 positioned relatively to its seat 19 by a piston 18 subjected to the pressures on opposite sides of a restriction 17 to maintain a constant rate of liquid flow at 16 beyond the restriction. The piston is loaded by a spring 2 and hunting is prevented by a dashpot device comprising a piston valve 4 and a piston 3, the spring acting between the piston and the head 1 of the valve and being initially compressed. The piston is slidable on the valve and in a cylinder 7 which has a connection 5 with the inlet line 15 of the flow controlling valve, and an exhaust connection 6. A liquid filled chamber 8 in the cylinder is connected to the interior of the piston 3 by a passage having a throttle 9. Upward movement of the piston 18 compresses the spring 2 and moves the valve 4 to connect the chamber 8 to exhaust, whereby the piston 3 follows the valve at a speed determined by the throttle 9 to close the valve and return the spring to its initial compression. Downward movement of the piston 18 causes extension of the spring and movement of the valve 4 to connect the chamber 8 to the inlet whereby the piston 3 slowly follows the valve to recompress the spring and cut-off the inlet.

GB - 02.04.1952

Int.Class F02B 75/32 Appl.No 1069549 Applicant STEWART STEWART TRESILIAN Inventor

669,349. Construction of crank-chambers and cylinders: driving-gear; valves and valve-gear. TRESILIAN, S. S. April 19, 1950 [April 22, 1949], No. 10695/49. Classes 7(ii) and 7(vi) To permit operation. at normal mean piston speeds in a four-stroke, engine for motor vehicles having poppet valves and a piston stroke equal to or less than threequarters piston diameter, inertia forces in the valve gear are reduced by providing at least two inlet, and possibly two or more exhaust, valves to each cylinder. As shown, applied to an overhead-valve engine, two inlet valves 66a; 66b, Figs. 7 and 10, and a single exhaust valve 69 are employed opening into an L-shaped combustion .chamber in a detachable cylinder head 50, which is formed with a tunnel 50a mounting and enclosing the valve gear which comprises a chain-driven cam-shaft 52 operating the valves directly through rockers 58. Inspection covers 59, which may be light metal pressings, are provided. The inlet valves. 66a, 66b are served, by a single inlet passage from the manifold 65a. A sparking plug bore 72 is provided. Further to reduce reciprocating masses, the piston 20, Figs. 1 and 2, is of cast light alloy and is driven from a crank-pin 30 through pin-and-slot mechanism comprising a bronze or like split bearing block 28 sliding in transverse, guides 31 (which may have bonded iron or steel inserts as shown) in the piston 20, itself slidable in guideways 25 in a crankcase 26. The head of the piston 20 may be connected to its neck 22, which consists of spaced legs stiffened, as shown, by webs 39, 40, by countersunk screws or nuts. The cylinder 21 may be detachable from the crankcase 26, which is closed at the bottom by a sump 42 and has part. cylindrical side-bays 27 to accommodate the movement of the bearing block 28. Main crankshaft bearing blocks 35,. 36 are.secured to the crankcase crown by bolts 37, and the crankcase walls are stayed by the tie 41. A similar construction may be used with an opposed piston engine. As applied to a side-valve engine having a normal connecting rod assembly, a single exhaust valve 87, Fig. 12, parallel to the axis of the cylinder 90 and two inlet valves 86a, 86b inclined slightly relative. thereto are directly operated through tappets from a side-mounted cam-shaft, the inlet valves of adjacent cylinders being served by a single passage 91. In a modification applicable to an engine having four cylinders 90, Fig. 13, two inlet passages 91a each serve four inlet valves 86a, 86b, the exhaust valves 87 being served by passages 92a, 92b. According to the Provisional Specification (a) the rockers 58 for the inlet and exhaust valves respectively are mounted on separate spindles, (b) the piston 20 has a detachable bottom cover for assembly purposes, and (c) normal connecting-rod assemblies for use with engines accordisg to the invention may have roller big-end bearings, magnesium-base light alloy pistons and magnesium-base or aluminium-base light alloy connecting-rods or a deeply finned big-end construction of the kind in which the connecting-rod and bigend bearing cap have serrated interengaging faces and jointly provide a radially-thin bearing ring.

10.663526Improvements relating to liquid operated servo mechanisms

GB - 27.12.1951

Int.Class F15B 11/10 Appl.No 707048 Applicant LUCAS LTD JOSEPH Inventor IFIELD RICHARD JOSEPH

663,526. Fluid-pressure servomotor control systems. LUCAS, Ltd., J. April 6, 1949 [March 8, 1948], No. 7070/48. Class 135. A fluid pressure servomotor system comprises a piston 16 movable in a cylinder a under liquid pressure under the control of a valve d operated by an actuating member such as the diaphragm e, itself controlled by a number of normally-open control valves o, p, q arranged in series. The valves o, p, q are responsive to different controlling factors such as the speed of a pump, the rate of fluid delivery, temperature, blower delivery pressure or atmospheric pressure. Thus the valve o is actuated by a solenoid 7 controlled by a thermally or manually operated switch (not shown). The valve p is actuated by a capsule g responsive to blower or other pressure, and the valve q is actuated by a spring-loaded diaphragm 11 exposed through a port 13 to the discharge pressure of a pump and responsive therefore to the speed of the pump. The valves o, p, q are opened by springs 2, 3, 4 and have restricted by-passes x, y, z which may be separate channels as shown or may be provided in either of the valve closure surfaces. The final valve q has an exhaust outlet n. The diaphragm e is loaded by a spring f in a chamber g having a connection 20 to atmospheric or other pressure. The chamber below the diaphragm is supplied through a restriction h from the same source 22 as supplies the servocylinder a through a further restriction 19. A spring 17 maintains the piston 16 in its upper position until an outlet b is opened by the valve d. The piston 16 may control the output of a swashplate pump supplying liquid fuel to a furnace or the combustion chamber of an engine. Alternatively it may control a throttle valve. Fig. 2 shows a modification in which the by-pass passages x, y, z are dispensed with, since the valve d has a direct outlet n1 to exhaust. In this case the control pressure acts in a chamber g above the valve and passes through the valves o, p, q to exhaust in the reverse order. In another modification, the valve d is formed as a piston and has a direct passage to exhaust. The valve d in this case controls two servopistons simultaneously. In a still further modification, the valve d is of spool form and controls the inlet and exhaust of pressure liquid to and from both ends of the servocylinder.
