Patent number: 4821860Abstract: A friction material and carrier assembly (which is to be used in the construction of a driven plate of a dry friction clutch) comprises a circular carrier plate having at its periphery radially extending spokes or paddles which are elastically pliable axially of the carrier plate. Two annular friction facings which are resilient and capable of flexing are bonded by respective layers of silicone rubber to opposite sides of the paddles. Each rubber layer can be formed by a plurality of strips or beads of rubber. The paddles arrangement is capable of sinuous flexing circumferentially of the assembly, and when the assembly is in a driven plate in a clutch applying the clamp load specified for the clutch, the overall axial thickness of the combination formed by the paddles and rubber layers and the friction facings is reduced by between 0.05 mm and 2.00 mm.Type: GrantFiled: June 19, 1987Date of Patent: April 18, 1989Assignee: Automotive Products plcInventors: Peter F.

Patent number: 4796437Abstract: An economical heat pump system which uses a multifluid heat exchanger and the basic components of conventional heat pump systems including, as appropriate, a desuperheat exchanger. The invention may be operated in two conventional refrigerant flow configurations including heat pump space heating and cooling and simultaneous hot water heating via the desuperheater. The use of a multifluid heat exchanger allows the two refrigerant flow configurations to have nine operational modes. In one flow configuration the refrigerant is from the compressor, through the desuperheater, through a reversing valve, through the outdoor heat exchanger, through an expansion device, through the indoor heat exchanger and back to the compressor via the reversing valve. In the second configuration, the refrigerant flow is from the compressor, through the desuperheater, through the reversing valve, through the indoor heat exchanger, through an expansion device, through the outdoor heat exchanger and back to the compressor.Type: GrantFiled: October 23, 1987Date of Patent: January 10, 1989Inventor: Larry S.

Patent number: 4770448Abstract: A pipe joint coupling member for deep well pipe strings has a female thread with a slightly longer pitch than the standard API thread of the pipe end. The differences in pitch is predetermined so as to equal the elastic elongation of the pipe end threads due to loading of the made up joints when suspended in a well. The coupling, in addition to having a slightly longer thread pitch may also have a different taper or tapers than that of the standard pipe end.Type: GrantFiled: September 12, 1986Date of Patent: September 13, 1988Assignee: Landell International Company, Inc.Inventors: Albert L.

Patent number: 4770282Abstract: In a diaphragm spring clutch, a clutch driven plate is clampable against a rotatably driven counter - pressure plate by a pressure plate urged by a diaphragm spring. To cushion clutch re-engagements the pressure plate has an annular array of spaced lands facing the diaphragm spring and supporting a resilient fulcrum ring having spanning portions spanning the spaces between the lands, the spanning portions of the fulcrum ring being in contact with respective radial ribs on a face of the diaphragm spring. As the diaphragm spring increasingly urges the pressure plate during a clutch re-engagement, the spanning portions of the fulcrum ring are resiliently deformed by the ribs into the spaces between lands to axially cushion the re-engagement.Type: GrantFiled: January 29, 1987Date of Patent: September 13, 1988Assignee: Automotive Products plcInventors: Ian C. Maycock, Peter A. Romer, Steven Trotman

Patent number: 4759207Abstract: Transfer means for transferring a continuous elongate product, such as wire, bar or tubular products associated with a continuous extrusion machine, between two stations in the production line. Axial tensioning means 8, 10 each consisting of a pair of resiliently tyred wheels 12, 14 positioned to grip the elongate product 2 and driven by a low inertia, electric, motor induce an axial tension in the elongate product 2. The elongate product forms a curve 20 of catenary form between the axial tensioning means 8, 10. A control signal indicative of the gravitational deflection of the curve is derived from an ultra-light dancer arm 22, or an optical or ultra-sonic sensor, and is utilized in combination with a signal derived from product speed sensor means 24 to control the speed of the low inertia, electric, motors and thus the tension in the elongate product.Type: GrantFiled: September 30, 1986Date of Patent: July 26, 1988Assignee: Babcock Wire Equipment LimitedInventor: Daniel J. Hawkes

Patent number: 4758830Abstract: A switch/display unit comprises a dot matrix display, having two sets of elongate electrodes, one set being inclined to the other, these sets being applied to opposite sides of a display medium. A transparent dielectric panel is superimposed in front of the display, so that the first set of electrodes, which are formed from a transparent conductive material abut the rear surface of the dielectric panel. A transparent conductive layer is formed in front of the dielectric panel, so that it will capacitively couple electrodes of the first set of electrodes with other electrodes of the first set of electrodes or other electrodes on the rear surface of the dielectric panel. This capacitive coupling may be varied by touching or moving the conductive layer. By applying read pulses to one of the sets of electrodes that are capacitively coupled via the conductive coating and sensing the pulses transmitted to the other electrodes, actuation of the switch can be detected.Type: GrantFiled: April 26, 1985Date of Patent: July 19, 1988Assignees: TI Corporate Services Limited, Phosphor Products Co.
