Abstract: A torsional damper comprises at least two coaxial parts rotatable relative to one another within predetermined limits. A plurality of circumferentially acting elastic means are disposed between them in the circumferential direction. These elastic means comprise at least one block of elastic material extending in a substantially tangential direction. The or each elastic material block is partially housed, without circumferential clearance in a rest configuration of the damper, in an opening formed for this purpose in a first of the coaxial parts. It is further partially housed, with circumferential clearance in this rest configuration and for at least one circumferential direction, in an opening formed for this purpose in a second of the coaxial parts. The elastic material block carries at least one elastic material peg projecting from it in at least this circumferential direction.

Abstract: A hub lock for a coil forming machine has a spindle with a shaft telescopingly mounted within a tube that is concentric thereto. A metal part somewhat in the form of a top hat is positioned over an end of the tube. A resilient elastomer block is on the crown and abutting against the brim of said top hat shape. A pressure plate on the end of the shaft squeezes the elastomeric block so that it is pressed against the interior of a hole in a wheel fitted over the block.

Abstract: A constant velocity joint (10) comprises an input shaft assembly (12) and an output shaft assembly (14), each shaft assembly (12, 14) including a cylindrical end (30, 32, and 50, 52) received within a respective pair of arcuate surfaces (40, 42, and 60, 62) in the housing (16). A pilot assembly (70) is disposed between the input shaft assembly (12) and output shaft assembly (14), with a pin (90) extending between pilot members (76, 86) of the pilot assembly (70).

Abstract: A water conserving flush valve for use in a toilet tank is described. This flush valve is comprised of a valve, pivoting about an overflow tube contained in the tank, for directing water from the tank in order to produce a flush; means, responsive to rotational movement of a flush handle in a first direction for opening the valve in order to initiate a flush; and means, situated about the overflow tube and responsive to rotational movement of the flush handle in a second direction occurring at any time during the flush for forcing the valve to pivotally rotate to a closed position in order to pre-maturely close the valve, thereby limiting the amount of water consumed during the flush and, in turn, conserving water.

Abstract: The present invention provides an improved control system for a driven cable reel mounted on a vehicle wherein the reel is adapted to pay-in and pay-out electrical cable to supply power to the vehicle, such as a mine car. The control system modifies the torque supplied by the reel drive so as to maintain a relatively constant tension on the cable. The improved control system has a first or basic output which provides higher torque when the reel is paying in cable and provides lower torque when the reel is paying out cable, the difference in drive torque being necessary to compensate for the reversal of frictional characteristics during paying in and paying out of the cable. The control system further provides a transient condition output signal to modulate the drive of the cable reel in a manner which compensates for acceleration and deceleration of the cable reel to reduce cable slack and prevent a sudden increase in cable tension which could cause cable breakage.

Abstract: Apparatus for sequentially presenting a series of rolls of cloth or paper, etc. to an unwind device, the rolls being precisely positioned for automatically being grasped by chuck members on the unwinder.

Abstract: A drawing toy having a housing and a web of material upon which a child can draw, color or mark. The housing includes a generally cylindrically shaped shell formed of two generally semi-cylindrical halfs. A hollow spindle having the web of material wound thereon it is located in the shell in substantial coaxial relationship with one end of the spindle projecting from one end of the cylindrical shell. A cap is removably attached to the projecting end of the spindle so that as the cap is turned, the spindle is caused to rotate about the longitudinal axes of the shell to unwind the web from or rewind the web on the spindle. A slot is formed in the shell through which the web of material moves as the web is unwound and re-wound on the spindle.

Abstract: An elastomeric shear shaft coupling is disclosed for connecting two rotatable shafts in end-to-end relationship. The coupling includes hubs for mounting on the opposed ends of the shafts and a flexible element extending between the opposed hubs. Clamping members and suitable fasteners are used to secure the element to the hubs for transmitting the torque developed by the driving shaft to the driven shaft. The flexible element has a bead of harder material than the body of the element, disposed within or at the margins of the element in the locus of clamping, and is reinforced with a matrix of plies or layers of a suitable fabric material.

Abstract: Apparatus for releasably securing or chucking a workpiece such as a roll of web material includes a rotable member having a slot defined therein, with a ridig member or chuck blade pivotally mounted in the slot. Rotation of the workpiece in relation to the rotatable member pivots the rigid member and extends it so that the workpiece is wedged across the spindle and the rigid member. The rotatable member is offset from a rotatable spindle to compensate for misalignment caused by the wedging.
