491,955. Making wheel rims. KELSEYHAYES WHEEL CO. Dec. 11, 1936, No. 34088. Convention date, Jan. 20. [Classes 83 (ii) and 83 (iv)] Stamping.-Drop centre wheel rims are formed from hoops of a diameter substantially corresponding to that of the base of the well of the finished rim, portions on opposite sides of that forming the well base being expanded to the required diameter and shaped to the desired profile. The cylindrical rim blank A is first placed upon a die member B, Fig. 3, and forced downwardly by a die C to flare one end of the blank B<2>. The blank is next reversed in position on the die and again pressed downwardly by a die, shaped to fit the expanded end, to flare the other end of the blank. The arcuate section blank is then placed over a support G, Fig. 5, in finishing dies for shaping the rim to the section shown. The die portions I are in the form of slidable segments which are moved down the inclines J<1> by a ring K<1> carried by the upper die H to contract the die I on the rim to impart the required form during axial compression between the dies G, H. In a modification, the first two steps of the process are performed simultaneously in dies in which the blank is gripped centrally and internally.

Filaments, ribbons, fabrics, films, and like materials having a basis of cellulose acetate or other cellulose ester or ether, containing a plasticizer or other substance soluble in a liquid which is a non-solvent for the cellulose derivative, are rendered more resilient by dissolving out at least a part of the plasticizer or other substance, and simultaneously or immediately thereafter impregnating the materials with a substance or mixture of substances which are capable of reacting to form a resinous condensation product, and heating the materials to effect the condensation. The treated, materials have a high resistance to creasing, and their affinity for acid dyes and resistance to water are increased. Removal of plasticizer and impregnation with the resin-forming substances may be effected in a single bath. The solvent for the plasticizer may have a swelling action on the cellulose derivative. The plasticizer may be an alkyl phthalate, benzyl acetate, an acetin, tribenzoyl glycerine, an aryl phosphate, or an alkyl tartrate. Other readily removable substances which may be present in the cellulose derivative are ethyl lactate, diacetone alcohol, lactic acid, citric acid, alcohol or acetone soluble portions of resins such as rosin, shellac, and kauri. Liquids which may be used for removing the plasticizer or other ingredient are methanol, ethanol, methylal, ethylal, methyl formate, methyl acetate, aqueous solutions of acetone, methyl ethyl ketone, or dioxane. The synthetic resin components may be added in the form of an intermediate reaction product such as di-methylol urea. Urea and formaldehyde may be used in the proportion of three molecules of urea to two of formaldehyde. Other resin components are acetaldehyde, benzaldehyde, furfurol, and acrolein, and thiourea, dicyandiamide, guanidine, biuret, methyl urea and ethyl urea. Resins of the diphenylolpropane formaldehyde type may be formed in the materials. Condensation may be effected by passing the materials through a heated atmosphere or over heated rolls. After the drying step preparatory to the final heating the materials may be subjected to brushing, beating, or other treatment to remove resin-forming substances from the outside and to prevent the formation of a coating. Similar treatment may be carried out after the final heating. The materials may be scoured with a dilute alkaline solution. In an example, cellulose acetate yarns containing dimethyl phthalate are woven into fabric which is then soaked in a methanol solution of a ureaformaldehyde reaction product. This reaction product is obtained by adding caustic potash to a solution of urea and formaldehyde in methanol, heating for a few minutes, cooling, adding acetic anhydride, and before use, acidifying with sulphuric acid. The reaction product may be formed in aqueous methanol, aqueous caustic soda being added before the heating, and acetic acid being added after heating and cooling. The fabric is removed from the solution, dried in air, and heated to effect condensation of the resin components. It is then passed through a fabric breaker. Effects such as embossing or crimping produced on the treated materials are more permanent. The polymerization or condensation may be localized. Specification 485,199 is referred to. The Provisional Specification refers also to Specification 485,372.

492,018. Drilling, milling, &c. machines. MACRAE, W. L., and LAPHAM, DE F. A., (trading as DALRAE TOOLS CO.). Feb. 18, 1938, No. 5121. Convention date, Oct. 7, 1937. [Class 83 (iii)] In a drilling, milling, or like machine tool a rotatable shaft is used for causing relative movement between the tool and work and a mechanical counter of the multiple register-wheel type is connected to the shaft in order to indicate relative movements of the tool and work. The tool spindle 15 is mounted in bearings 17, 18 in a quill 24, axial play of the spindle being taken up between a nut 21 thereon and the tool chuck 20, and a spacing sleeve 22 being provided between the bearings. The quill 24 is splined within a bearing 25 by a key 26 and may be clamped in any adjusted position by means of a hand-operated screw 28 engaging the key. A screwed part 33 of the quill is surrounded by a nut 31 having worm teeth 36 engaged by a worm 34 on a shaft 35, to either end of which a hand wheel 40 may be attached. Thrust bearings 32, 39 prevent axial motion of the nut and worm. The spindle is rotated by a belt drive from an electric motor, (not shown), to a multiple speed pulley 42 splined to the spindle and mounted on the casing 11 in bearings 43. A gear 61 on the worm shaft 35 drives, through an idler 62, the pinion 60 of the counter 46, the arrangement being such that one thousandth of an inch of axial movement of the spindle 15 registers one unit on the counter. The idle gear 62 is rotatably mounted on a fixed pin 63 and carries a flange 66 whereby it may be slid axially to disengage the drive to the counter, the two positions of the gear being determined by a spring detent. The counter may be set to zero when the tool engages the surface of the work by engaging a handle 55 therewith through a clutch which is normally held disengaged by a spring, and the counter will then register the depth of penetration of the tool into the work in thousandths of an inch.

492,078. Cleaning gear cases &c. AERO EQUIPMENT CORPORATION. Sept. 8, 1937, No. 24473. Convention date, Sept. 15, 1936. [Class 116] [Also in Group XXVIII] An apparatus for cleaning gear cases &c., in which the cleansing liquid is injected and withdrawn by air pressure, is provided with a transparent chamber 38 in the liquid pipe 52. The apparatus comprises a container 10 having an air pressure pipe 14 connected to an injector device V. When the valve 20 is opened, air passes through the injector and out of the opening 26 drawing out the air in the chamber 10 and drawing in liquid through the pipes 52, 32. When the opening 26 is blocked, the air under pressure forces the liquid in the chamber through the pipe 52. The manner in which the cleaning operation is proceeding is determined by observing the clarity of the liquid passing through the transparent chamber.

10.492037Improvements relating to apparatus for feeding articles in sorting and like machines

GB - 12.09.1938

492,037. Delivering rice &c. from hoppers ; sorting-mechanism ; centrifugal feeding - machines. ELECTRIC SELECTORS, Ltd., and HORSFIELD, W. R. March 10, 1937, No. 7107. [Class 78 (i)] [Also in Group II] For distributing rice and like grains supplied in bulk from a hopper so that they are delivered singly, for example past photo-electric-cell sorting-mechanism, a centrifugal disc is used in combination with an inverted spiral guide. Thus, rice delivered from the hopper 10 by a rotating tube 12 strikes a ledge 24 in the shoot 22 which loosens adhering dust for removal by an upward current of air. The dust-freed grains then fall through an orifice 44 on to the rotating plate 26 which co-operates with a non-rotating cover member having a spirally-ribbed under surface 46. The surface of the, rotating plate preferably is curved so that as the centrifugal force increases with the progress of the grains towards the periphery, an increased gravitational drag is introduced, so that the resultant of these two forces is at a constant angle to the normal to the surface. This is stated to result in the grains becoming spaced apart with their longitudinal axes all in the same direction, so that they are delivered singly to the L-shaped guide 52 and carried therealong by their momentum at right-angles to the plane of the paper past the photo-electric-cell sorting-apparatus. As shown, the cross-sections of the curved surfaces of the member 26 are arcs of circles of which the centres are displaced from the axis 28, which approximates to a concave toric shape forming the best construction. The spiral ribs 46 which just clear the curved surface and are normal thereto at all points, are made as smooth as possible. The plate 26 and tube 12 are both driven by belting from the shaft 74. The surface of the plate is grooved or roughened and it has a very narrow flattened portion at the outer edge of its upper surface. Specification 492,035, [Group XL], is referred to.
