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 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.

Abstract: A formable hose with a reformable wire embedded solely in a thicker portion of the hose cover, the reformable wire oriented longitudinally of the hose.

Abstract: A toothed belt having fore and aft tooth flank surfaces defined in cross section by arcs having radii generally equal to the pitch spacing of the belt teeth. A sprocket having teeth with fore and aft flank surfaces defined in cross section by arcs having radii generally equal to the pitch spacing of the sprocket teeth. In combination, a drive comprising the belt and sprocket as described.

Abstract: A hose of improved impulse life is described including an inner polymeric tube which has a relatively hard outer surface, a tightly packed wire reinforcement e.g., braid or spiral, telescoped over the tube, and an expanded polymeric cushion matrix encapsulating at least a portion of the strands of the reinforcement and also promoting wire-to-wire and tube-to-wire adhesion. A method for producing the hose employing a foamable material applicator is also disclosed.

Abstract: A non-pneumatic tire for a wheelchair or other wheeled apparatus includes an endless integrally molded solid core rubber tire with a tensile member embedded in the tire to minimize chance of roll-off of the tire from an associated rim. A method for producing the tire is disclosed.

Abstract: A method for making a powdered metal ferrule by compacting and sintering powdered metal to have a density of at least 80 percent of the theoretical maximum compacted density and an elongation of at least 2.9 percent; and powdered metal ferrule having a density of at least 80 percent of theoretical maximum compacted density and an elongation of at least 2.9 percent.

Abstract: An electrochemical cell of the limited electrolyte type is described having a cell pack comprised of the normal absorbent separator interleaved and compressed between positive and negative plates, the electrolyte absorbed within pores of the separator and plates, and a container encasing the cell pack. The cell pack has an edge or edges which abut against at least one wall portion of the container, forming an interface in which is formed channels providing passageways which promote uniform distribution of electrolyte within the cell pack at least during filling of the cell with electrolyte. Filling time is also substantially reduced.

Abstract: A multi-layered gas permeable separator for lead-acid maintenance-free batteries, particularly for sealed gas recombining type rechargeable lead-acid batteries, is disclosed. The outer separator layers, adapted to be positioned against the opposite polarity plates of the battery, are composed of ultrafine fibers particularly glass fibers of relatively high fiber surface area. A third layer is interposed between the outer layers and is comprised of ultrafine fibers particularly of fiber glass, but has a fiber surface area on an equivalent weight basis which is substantially less than that of at least one of the outer layers. High rate, low temperature discharge performance of the battery is enhanced.

Abstract: A polymeric thread protector with a generally sleeve-like cylindrically shaped body having a perforate sidewall and a means for retaining the body to a threaded member, is positioned over threads of the threaded member and is retained in place while the threaded member is placed in a plating solution and plated.

Abstract: A deformable ferrule for use in coupling hose which has a sidewall portion that decreases in thickness going longitudinally of the ferrule from a fitting end to a hose end. A method of deforming an exterior frustro-conical surface portion of the ferrule to a generally cylindrical shape while simultaneously forming an inside surface portion of the ferrule to a generally frustro-conical shape.

Abstract: A recombining lead-acid battery with absorbed electrolyte is disclosed having multiple cells positioned in a sealed monobloc container, and cell partitioning members constructed to define a gas space common to all the cells of the battery. When the battery is overcharged imbalance in electrolyte fill among the cells is reduced as the amount of water in each cell tends to equalize through redistribution via gas recombination preferentially in the drier cells.
