Abstract: A power transmission wheel of the gear wheel sprocket wheel and pulley wheel type has hub portion or rim portion formed of a composite material of discontinuous fiber disposed in a plastic matrix where teeth are formed in one of the portions so as to define flank surfaces and where lateral side portion of fiber follow the contour of the surface so as to minimize in portions of fiber at ends the flank surfaces. A method for manufacturing a power transmission wheel by winding a strip of uncured material having embedded discontinuous lengths of fiber, and winding the strip in a volute fashion to form a preform having oppositely facing sides, and pressing the preform on one side and shaping the preform, and heating the preform to define a power transmission wheel.

Abstract: A sensing element includes a body of pressure sensitive electrically conductive material formed by a non-conductive matrix of flexible elastomeric material, the matrix containing electrically conductive particles. The body is formed with spaced connection regions, at least one of which is a hole into which an electrical connector may be inserted as a push fit. The connector is oversize in a direction transversely of the hole to ensure that the connector is held in place in the body and makes good electrical connection therewith.

Abstract: The composite sealing element of the invention includes an elastomeric sealing lip portion and a base portion, chemically bonded to the sealing lip comprised of an elastomer reinforced with discrete dispersed fibers oriented in a preferential manner, and the sealing lip and base portions being chemically bonded together such as by covulcanization to form an integral sealing element resistant to delamination. The method involved forming a fiber loaded sheet in which the fibers are oriented generally unidirectionally, plying up the sheet to form the base portion of the sealing element, and molding the finished article under heat and pressure.

Abstract: A conduit coupling member for use with a second coupling member, comprising: a generally tubular body having a bore along its longitudinal axis; an integral and portion of the body having a nose portion and an annular groove in the bore juxtaposed the nose portion which together define a cantilever lip deflectable at least partially in a direction of the longitudinal axis; and the nose portion having an outer surface, a portion of which effects a seal when the lip is longitudinally deflected.

Abstract: A method of assembling a connection for branched radiator coolant hose in which the hoses to be connected are adhered onto the ends of a T-shaped connector. Then a capsule of rubber is molded around the area of the connection and cured to form a unitary and integral connection.

Abstract: A flat type power transmission belt with an embedded tensile member of first and second plies of yarns where a first layer of yarns is disposed at a first helical angle and a second layer of yarns is disposed at an opposite helical angle. A method for making flat belts by making a sleeve and embedding a tensile member therein by winding a first plurality of yarns at a first helical angle and then winding a second plurality of yarns in a second layer at an opposite helical angle.

Abstract: A method of manufacturing a sensing element, comprising bringing a first body in the form of an oil-free cross-linked matrix of flexible elastomeric material, the matrix containing electrically conductive particles, into contact with a second body of flexible elastomeric material that is electrically insulating and that contains an oil compatible with the elastomeric material of the first body, and allowing oil to migrate from the second to the first body so as to cause swelling of the first body, the migration continuing until a state of oil phase equalisation between the two bodies is reached.

Abstract: A method of making a power transmission belt with discontinuous fibers by forming oppositely facing friction driving surfaces by grinding such that fiber protrudes from the driving surfaces and is bent exposing lateral side portions of fiber.

Abstract: A method for making an Airspring and Sleeve that each have a chamber portion and rolling lobe portion reinforced with successive layers of embedded cord by winding cord in one layer at opposite helical angles from cord of a second successive layer and winding cord at inconstant helical angles in an annular band portion of at least one of the sleeve portions.

Abstract: A tension compensating gear set of the eccentric type for use with a flexible power transmission member with a gear member having at least one external circumferential surface in rolling contact with an internal circumferential surface of an annular gear method for controlling tooth meshing while inhibiting noise or vibration. An eccentric gear set is used as a method or means for automatically adjusting for fluctuations in center distance of a power transmission drive system.

Abstract: A fitting for installing on the terminus of large scale industrial hoses and method of making it and installing it, in which two annular steel rings are welded onto a cylinder formed of expanded metal, which subassembly is then mounted over an extruded rubber tube and is then wrapped with a friction layer of rubber, a braided textile reinforcement layer, steel cable reinforcement, and a wrapped or extruded rubber outer cover. A hump is built up over the annular ring welded on closest to the end of the expanded metal cylinder, and a flange is then butted up adjacent to this hump to effect installation of the end of the hose. During curing, rubber freely flows through the expanded metal cylinder, securely embedding the fitting within the hose.

Abstract: A device for absorbing the energy of vibration of one of two abutting members which has begun to vibrate due to forces applied to either of the two abutting members, so as to reduce the frequency and magnitude of vibration of one of the two abutting members. The primary energy absorbing element is a piece of elastomeric resilient material which contains a core (or cores) of a substantially incompressible, highly efficient dampening material; the presence or absence of this core of highly efficient dampening material will depend upon desired device stiffness and dampening characteristics. The primary energy absorbing element is surrounded by a flexible reinforced shell which contains and restrains said element, yet allows said element to deform in the transverse and vertical directions. Two end pieces or mounting plates are secured to opposite ends of the primary energy absorbing element.
