Abstract: A torque transmitting device is adapted to transmit torque from an input (32) and includes a first member (14), a second member (16) rotatable relative to the first member about an axis of rotation (24), an operating chamber (18) disposed in the first member, a fluid reservoir (70), a fluid passageway (74) communicating with fluid reservoir in the operating chamber and a valve member (82) for controlling the fluid flow through the fluid passageway. A fluid is disposed in the reservoir and is selectively displaceable into the operating chamber through the fluid passageway whereby fluid is positioned in the operating chamber to transmit energy through the fluid from one of the members to the other. A thermostatic ring (90) is connected to the valve member for controlling the position of the valve member and the volume of the fluid in the operating chamber in response to the ambient temperature of the torque transmitting device.

Abstract: A differential assembly includes a case (12), an input (30) for effecting rotation of the case, pinion means (36, 38) associated with the case, a pair of side gears (32, 34) meshing with the pinion means, a first output shaft (26) connected to one of the side gears and a second output shaft (28) connected to the other of the side gears. The differential assembly further includes a first gear train (54) associated with the first output shaft and rotatable therewith, a second gear train (52) associated with the second output shaft and rotatable therewith, and a third gear train (30, 70) associated with the casing and rotatable therewith. A first clutch (80) is provided for interconnecting the third gear train and the first gear train to enable the third gear train to supply additional torque through the first gear train to the first output shaft when the rotational speed of the input exceeds the rotational speed of the first output shaft by a predetermined amount.

Abstract: A gate turn-off device is formed by the integration of a lateral SCR and a vertical power transistor operating in parallel, with the latter carrying most of the load current whereby the former may be easily turned off which in turn terminates base drive to the transistor and thus the device is turned OFF.

Abstract: A control valve assembly (10) is provided for controlling a hydrostatic transmission including a fluid pump having a variable swashplate, a source of control fluid under pressure, and a servo system responsive to the control fluid for varying the swashplate of the fluid pump. The control valve includes a valve body (12), first (26) and second (28) fluid chambers disposed in the valve body, a first fluid passageway (30) disposed in the valve body for directing pressurized control fluid to the first and second fluid chambers and a valve member (16) located in the valve body for controlling the flow of control fluid to the servo system. The pressurized fluid in the first fluid chamber acts on the valve member to bias the valve member in a first direction and the pressurized fluid in the second chamber acts on the valve member to bias the valve member in the second direction opposite the first direction.

The first torque transmitting member includes a first torque transmitting surface which is adapted to engage with the second torque transmitting member to establish a driving relationship between the driving and driven members and a second surface disposed remote from the first surface.

Abstract: An annular tire building drum having an infinitely variable width for use in a tire building machine includes a hub rotatable about an axis of rotation and an annular fluid expandable tube supported on the hub. The tube includes support means disposed on the exterior surface thereof. A plurality of pairs of shoe members are supported on the support means for movement in a radial direction upon expansion and contraction of the tube. The shoe members define an annular tire building surface. One of the shoe members of each pair of shoe members is movable in a first direction parallel to the axis of rotation and the other shoe member of each pair is movable in a second direction opposite the first direction to infinitely vary the axial width of the building surface. The support means includes guideway means and each of the shoe members includes a guide member attached thereto.

The tube element includes an outer peripheral surface upon which support means is secured for movement therewith. A plurality of shoe members are connected to the support means for movement therewith with the shoe members defining an annular building surface thereon which is movable in a radial direction toward and away from the annular support drum upon contraction and expansion, respectively, of the tube element. The tube element is expanded to expand the diameter of the building surface to enable a tire portion to be built thereon and retracted to decrease the diameter of the building surface to enable a build tire portion to be removed therefrom.

Each of the shoe members includes means on the first surface thereof which is connectable with one of the lugs on the tube element to support the first surface of the shoe member contiguous to the exterior surface of the tube member.

Abstract: A molding apparatus for manufacturing a molded golf club grip includes a mold member having a generally cylindrical shaped cavity disposed therein and defined by an internal annular surface. The cavity has a longitudinal axis and a circular cross sectional configuration. An elongate core bar is disposable within the cavity with the longitudinal axis of the cavity and the core bar being coextensive. The core bar has an external surface which is spaced apart from the internal annular surface of the mold member when the core bar is disposed in the cavity and the annular surface of the mold member cooperates with the external surface of the core bar to define a molding cavity for receiving a moldable material therein for molding a golf club grip.

Abstract: A fluid expandable drum for building portions of tires in a tire building machine includes an annular supporting drum and an expandable annular tube element having an inner peripheral surface supported on the annular drum. The tube element includes an outer peripheral surface upon which building means is secured for movement therewith.

Abstract: An expandable carrier apparatus for transferring a tread and a radial tread ply band from a first work station to a further work station in a tire building machine includes an annular support member and a fluid expandable annular tube element having an upper wall portion and a lower wall portion. The lower wall portion of the tube element is movable radially away from the upper wall portion upon expansion of the tube element and is movable radially toward the upper wall portion upon contraction of the tube element. The upper wall portion includes an annular peripheral surface which is bonded along a portion of the width thereof to the support member and the lower wall portion includes an annular outer peripheral surface having a plurality of gripper means disposed in an annular array supported thereon which are operable to engage and grip tread and a radial tread ply band upon expansion of the tube element.

Abstract: The present invention provides an eddy current coupling including an input member, an output member rotatable relative to the input member and an interdigitated pole assembly attached to the output member for rotation therewith. A field coil is provided surrounding a portion of the interdigitated pole assembly and an inductor member is connected to the input member. The field coil when energized establishes a flux field which couples the pole assembly and the inductor member to thereby couple the input member to the output member. The interdigitated pole assembly includes a core portion which is surrounded by the field coil and a plurality of pole members which extend at one end thereof from said core portion and have a pole face at the opposite end thereof with the pole faces of the plurality of pole members extending in opposite directions in an interdigitated fashion. The numerical value of the total surface area of the plurality of pole faces of each of the pole members is equal to between 2.
