Abstract: A power transmission belt of the V-block type with polymeric portions that define frictional driving surfaces. Extended polymeric portions are oriented transversely to the belt and are deflected such that successive blocks are in pressing contact with each other.

Abstract: A variable speed belt drive transmission system with a driven pulley having a movable pulley half operated to move axially with generated axial forces that decrease from where the driven pulley is closed to where the driven pulley is open, the maximum generated force being from about 100 to about 120 percent of a required pulley axial force where theoretical belt slip could occur.A method for enhancing belt life by controlling belt tension with driven pulley axial force by establishing a required driven pulley axial force that decreases from where the driven pulley is closed to where the driven pulley is open, the generated force lines being from about 100 to about 120 percent of a determined pulley axial force line where theoretical belt slip impends.

Abstract: A method for making curved hose using a curved mandrel by applying a melted material to an inside surface of an uncured hose and solidifying the material. The material is remeltable and forms a lubricant when the hose is pushed onto and removed from a hot curved mandrel.

Abstract: An alternating rotary to reciprocating type actuator with two axially spaced disc members that each have a plurality of circumferentially spaced rim grooves. A cord is wound in zig-zag fashion between the disc members and in the grooves to define a plurality of similarly arranged links that interconnect the disc members.

Abstract: A through-the-wall intercell connection for adjacent cells of a battery in which integral extensions of the current collector tabs emanating from the respective plates are directly welded together at the partition opening. The individual tabs are bent along a smooth curve which, together with interposed cushioned insulating material between bent tabs, lends vibration resistance to the intercell connection.

Abstract: A conductive elastomeric ink is described comprised of very fine nickel particles admixed in a silicone binder. The ink has utility in elastomeric switch control devices, printed circuits and the like.

Abstract: The subject invention relates to methods and materials for making porous resin rigidified shaped articles suitable for filters, surgical trays, and the like, which comprises the steps of impregnating a non-woven fabric with a predetermined amount of thermoplastic or thermosetting water-based epoxy resin; partially curing the resin-impregnated fabric; and, thereafter molding the partially cured fabric into a desired shape with sufficient heat to advance the curing of the resin.

Abstract: A polymeric type joint packing having a garter spring circumferentially oriented near one packing end where the garter spring has a helical core diameter that is greater than a radial gap to be sealed by the packing.

Abstract: An O-ring assembly with a generally piston-like shape elastomeric body that is radially extensible and has a circumferential groove which retains a circumferentially extensible O-ring.

Abstract: An electrode plate group combination insulator and vibration support at least partially envelopes a plate group connecting strap. The insulator and vibration support includes a comb-like portion which underlies the strap, having teeth which intermesh with tabs projecting from the plates, and a hood portion which overlies the strap. The insulator and vibration support is preferably attached to the walls of the cell of the battery to thereby support the battery plate group and withstand vibrational forces.

Abstract: A method for shifting a transmission with a predominantly mechanical speed sensing actuator to within a 10 percent shifting zone around a chosen operating line on an engine rpm/torque map by matching the force balance of the driver pulley to a force balance on the driven pulley.A variable speed belt drive transmission system with a predominantly mechanical speed sensing driver pulley and a torque sensing driven pulley that responds to an operating line, monotonic in torque having a slope from about 0.004 lb-ft/rpm to about 0.060 lb-ft/rpm where the driver pulley has an actuator that controls speed for a chosen torque value. The actuator has at least one centrifugal weight connected to an end of a torque producing spring to wind the spring. A second end of the spring is operatively connected through an articulated linkage to a movable half of the pulley such that the generated axial force is not directly proportional to square of the speed.

Abstract: A shock-absorbing torsionally elastic power transmitting device is described having resilient cushioning means loaded with modulus-increasing fibrous reinforcement, adapted to be interposed between mating lugs of a hub and rim configured to accommodate high torque levels simultaneously with relatively large angular deflections. The fibrous reinforcement is preferably aligned in the principal direction of displacement of the cushions under load. In another aspect, a torsionally elastic power transmitting device is used with V- or V-ribbed belt friction drive sheaves subject to slippage, to absorb torsional shocks and minimize heat build-up.

Abstract: A bristle for railway roadbed brooms with a trailing edge that has a plurality of spaced apart grooves that are oriented transversely of the bristle in the trailing edge portion.

Abstract: A cushioned panel is provided together with a method of molding it. A non-woven fabric having an outer layer composed of polypropylene or other thermoplastic fibers is heated to the melting point of the fibers. It is inserted into a mold having a decorative surface fabric and a piece of foam cushioning therein. The mold is designed so that the edges of the male and female mold halves compress the molten non-woven substrate and the surface fabric forcing the molten surface of the substrate into the interstices of the surface fabric. A mechanical bond is formed upon cooling.
