2.WO/1982/004370OFF-PEAK ELECTRIC HEAT STORAGE SYSTEM HAVING EXTENDED HEAT WITH-DRAWAL

WO - 09.12.1982

Clasificación Internacional F24D 11/00 Nº de solicitud PCT/US1982/000756 Solicitante VAPOR CORPORATION Inventor/a McKENNEY, James, Lee

An energy storage system for using electrical energy during 'off-peak' periods thereby 'equalizing' electric generating capacity and improving the efficiency of an electrical utility system employs a heat storage fluid, either liquid or gas, stored in a single elongated master tank (6) and at least one elongated slave tank (7). The master and slave tanks (6, 7) are vertically disposed and are each provided with an electric immersion heater (60, 61) controlled by a temperature controller (52, 52a) and energized during 'off-peak' periods by conventional controls to heat the storage fluid to a high temperature. Bottom outlets on the tanks (6, 7) are connected in parallel to the inlet of a variable output pump (25) which circulates the heat storage fluid through the central conduit (22) of a concentric tube heat exchanger (20), disposed coaxially about the lower extremity of master tank (6), and back to the tanks (6, 7) through a tank sidewall inlet. An aquastat (59) responsive to the temperature of heating system water flowing through annular flow space (23) of heat exchanger (20) controls theoutput of pump (25) in accordance with heating system demand. Each tank (6, 7) is provided with a vertical standpipe (53, 54) having an open top (50, 51), a bottom connected to the tank outlet and a small lower orifice (41, 42) located below the tank inlet. The standpipe (53, 54) apportions flow of heat storage fluid between the upper and lower portions of the tank in accordance with pump output and establishes an ascending thermocline in the tank between the heat storage fluid returned through the tank inlet and the higher temperature heat storage fluid remaining in the tank to minimize mixing and temperature dilution therein so that heat can be supplied to the system water at temperatures consistently higher than would be available with the prior art horizontal tank configurations. The disclosed heater reduces piping and weight, eliminates necessity of a thermal mixing valve and minimizes 'flashing' of the heated system water.

5.WO/1983/001531METHOD AND APPARATUS FOR POSITIONING A TRANSDUCER USING EMBEDDED SERVO TRACK ENCODING AND MICROPROCESSOR CONTROL

WO - 28.04.1983

Clasificación Internacional G11B 5/596 Nº de solicitud PCT/US1982/000683 Solicitante DATA PERIPHERALS Inventor/a NALLEY, Robert, E.

A system and method for accurately positioning a transducer means (24) radially in alignment with a selected data track on a magnetic disc (22) using microprocessor control (54) and for maintaining its radial alignment. Sectored servo track (30), radially interspersed with data tracks on a magnetic disc, are uniquely encoded within groups, the code comprising the location of recorded servo signals at either a first or second position within a plurality of data frames located on the servo tracks. The recorded servo signals are detected by a transducer (24) and compared with a D.C. voltage in a comparator (44) in order to produce a series of clock pulses for a shift register (46). A predetermined sequence of pulses corresponding to possible locations for recorded servo signals within the data frame in a sector (30) is the data input to the shift register (46). The output of the shift register (46) is a binary number corresponding to the servo track or the data track with which the transducer means (24) is radially aligned. This information is processed to identify the radial location of the transducer means (24). A microprocessor (54) determined from this information the radial separation between the transducer means (24) and the selected data track and provides, if required, a signal to cause the transducer (24) to move radially.

A method of manufacturing a bearing unit for an automobile wheel, comprising the steps of grinding a bearing material (B) in the steps of simultaneously grinding an orbital surface (5) and a stepwisely cylindrical surface (6) and feeding back the deviation of the finished size of the surface (5) from the objective finish size to an inprocess control gauge (23) for controlling the grinding of a supporting surface (21) and stepwise shoulder surface (9) to simultaneously grind the supporting surface (21) and the shoulder surface (9); grinding an inwardly annular member (C) by the steps of grinding an orbital surface (11) and feeding back the deviation of the finished size of the surface (11) from the objective finished size to an inprocess control gauge (29) for controlling the grinding of the supporting surface (21) and the end face (10) of the side contacting the stepwise shoulder surface (9) to simultaneously grind the supporting surface (21) and the end face (10) of the side contacting the shoulder surface (9); and putting the member (C) on the stepwisely cylindrical surface (6) of the material (B) with the end face (10) in contact with the surface (9) of the material (B) in engagement, thereby eliminating the adverse influence of the outer peripheral orbital surfaces (5), (11) of the material (B) and the member (C) on the bearing gap.

8.WO/1987/006218CONSTANT CONTACT LAY-ON ROLL WINDER

WO - 22.10.1987

Clasificación Internacional B65H 19/22 Nº de solicitud PCT/US1986/000730 Solicitante JOHN BROWN, INC. Inventor/a PERRIGO, Michael, C.

Turret type winder which incorporates articulated constant contact lay-on rolls (10a, 10b), which are mounted concentrically with the chucks (14a, 14b) at the ends of the arms (27) of the turret winder. These articulated constant contact lay-on rolls are continuously repositioned radially during winding and are able to either maintain constant pressure or to reduce lay-on roll pressure as the film bundle diameter increases. This winder also maintains an essentially constant wrap angle on the lay-on roll between the web (13) and the lay-on roll to minimize web tension variations during transfer operations. This is accomplished with the articulated constant contact lay-on roll by continuous circumferential repositioning during turret rotation when transferring to a new core (12a, 12b), so that the lay-on roll remains in contact with the surface of the bundle and maintains an essentially constant wrap angle during the entire 180 degree rotation of the turret arms. This feature virtually eliminates poor winding and the resulting formation of scrap during the turret arm rotation operation when a new core is loaded. This winder also incorporates an improved web feed-in mechanism to control web tension which incorporates a moveable float roll (91), a clutch driven bowed roll (96), driven feed rolls (95, 95') with free wheeling bearings and a mechanism to adjust the winding chuck speed in response to displacements of the float roll. This improved feed-in mechanism substantially reduces web tension variations due to drag forces normally encountered in the feed-in mechanism. This invention also includes an improved method for winding film bundles whereby the nip pressure is varied during winding and then maintained at an essentially constant value during turret rotation by maintaining an essentially constant wrap angle of the web on the lay-on roll during turret rotation.

10.WO/2003/059561CORE DRILL

WO - 24.07.2003

Clasificación Internacional B28D 1/04 Nº de solicitud PCT/KR2003/000041 Solicitante SHIN HAN DIAMOND INDUSTRIAL CO., LTD. Inventor/a PARK, MUN-SEAK

The object of the invention is to provide a core drill used for forming holes in rock or concrete structures or extracting cylindrical samples, so-called cores, from rock or concrete structures. The core drill is designed to reduce the contact surface area of its cutting edge with the rock or concrete structures during a drilling process, thus minimizing frictional resistance between the cutting edge and the rock or concrete structures and thereby maximizing drilling efficiency. The core drill also smoothly discharges chips and effectively dissipates heat, thus minimizing abrasion of metal bond holding diamond tips on a shank and thereby having a lengthened life span. The core drill includes diamond tips (11) mounted along the end of a cylindrical shank (10) with a tapered external surface (14). Each diamond tip (11) has a sharp edge (12) with a notch.
