Abstract: Mandrel-cured, curved elastomeric hose is provided with an indexing mark that is formed prior to or during curing of the hose on the mandrel. The rigid curved mandrel has an exterior hose-bearing surface and an interior cavity. The cavity and exterior surface are connected by a small passageway or hole which is located where the index mark is to be made on the hose. A sleeve having a wall of uncured elastomeric material is mounted on the mandrel such that a portion of the sleeve covers the passageway. The mandrel having the sleeve mounted thereon is placed in an autoclave and subjected to steam pressure. The steam pressure forces elastomer material into the passageway and thereafter cures the elastomer sleeve into a hose. The pressure inside the cavity is approximately atmospheric at the introduction of the steam pressure. The cavity within the mandrel may be sealed except for the passageway or the cavity and the passageway may be vented to atmospheric pressure.

Abstract: A method of breaking loose a vulcanized hose from a rigid mandrel on which the hose has been vulcanized is described. A first end of the hose is clamped securely to prevent movement relative to the mandrel. The second end of the hose is clamped less securely so as to permit movement relative to the mandrel. Fluid pressure is thereafter introduced between the hose and the mandrel thereby causing the hose to increase in diameter and shorten in length, thus breaking the hose loose of its associated mandrel. The hose construction must be such that it will increase in diameter without rupture when subjected to sufficient internal pressure.

Abstract: Large diameter filaments are produced by increasing the cooling efficiency of a molten polymer as it exits a spinnerette orifice. The cooling is accomplished in a collar configuration having means for directing cooling air and an ionic discharge in a direction transverse to the axis of the filament as it passes through the collar.

Abstract: A resilient mounting of elastomeric material includes first and second insulators adapted for placement on opposite sides of the mounting surface. A spacer includes an elongated cylindrical portion and at one end a perpendicularly extending flat flange. The spacer is forcibly fitted into the first insulator thereby radially compressing the elastomeric material of the lower portion of the first insulator between the cylindrical portion of the spacer and the tubular portion of a metallic annulus which is bonded to the exterior of the first insulator. Upon installation, the mount is pre-compressed in both the axial and radial directions.

Abstract: The method of manufacturing an improved collapse-resistant corrugated hose of flexible elastomeric material including a tubular structure which preferably includes a single layer of textile reinforcement which may be of a knit construction. The tubular structure is formed to an outside diameter essentially that of the maximum diameter of the mold cavity then placed therein and vulcanized under heat and pressure to mold form cylindrical end portions and a corrugated central portion. A preformed wire insert is then placed in the troughs of the internal corrugations to provide resistance against collapsing when the hose is subjected to a vacuum or bending. The hose is particularly useful in automotive vehicle cooling systems.This application is a continuation of Ser. No. 504,228; Sept. 9, 1974, abandoned; which is a continuation of Ser. No. 353,151; Apr. 20, 1973, abandoned; which is a continuation of Ser. No. 166,138; July 26, 1971, abandoned.

Abstract: A configuration for a synchronous drive belt and pulley combination wherein each belt tooth has at least part of its fore and aft flank surfaces shaped in cross-section as the arc of a circle the radius of which is centered on the pitch line of the belt a distance W apart. Each tooth-engaging pulley cavity has at least part of its fore and aft surfaces shaped in cross-section as the arc of a circle the radius of which is centered on the pitch circle. The tips of the belt teeth and the bases of the pulley cavities are relatively shaped such that upon engagement of the belt with the pulley compressive stress is exerted from each cavity base through each engaging belt tooth.

Abstract: A removable track for an annular resilient tire having a plurality of shoes mounted on a belt at spaced-apart positions along the belt. Each of the shoes has groups of raised traction bars on the ground-engaging surface at spaced-apart positions transversely of the belt. Each of the groups of traction bars has at least two bars positioned at an acute angle to the leading and trailing edges. The groups may have two pairs of bars with supplementary bars between groups and at the ends providing continuations of the traction surfaces of the traction bars on adjacent shoes. Slots between the ends of the traction bars may also be provided for movement of soil out of the spaces between bars upon deflection and articulation of the shoes in operation.

Abstract: A heat and chemically resistant sealing member particularly for an electrolytic cell of the diaphragm type in which the cell includes a cell can for containing a brine solution, a rigid cell base for supporting the can and anode members disposed within the can. The sealing member comprised of at least one vulcanized rubbery polymer provides a compressive seal between rigid members of the cell and is subjected to the heat within the cell. After long periods of exposure to this heat the sealing member is of a relatively flexible, resilient rubbery nature and has a relatively high resistance to compression set to thereby retain its sealing properties. The sealing member is preferably a flexible elastomeric sheet particularly useful for providing a seal and cover for the conductive base of the cell.

The rubbery polymer is preferably polyisoprene and the plate-like or platy particles are preferably graphite or glass flakes.

Abstract: A removable track for a tire having at least one sealing member interposed between the annular belt of the track and the traction shoes clamped on the belt. The sealing member is under compression and has a surface of highly compressible material to conform to irregularities in the track assembly for sealing the space between the traction shoes and the belt. The sealing member may be of rubber or plastic foam so that during compression and decompression the space occupied by the sealing member may decrease and increase while the sealing member maintains a sealing relationship with the traction shoes and belt. The sealing member may also be adhered to the belt-engaging surface of a traction shoe or to the belt. Further, the sealing member may be positioned between adjacent traction shoes with overhanging ribs of the shoes engaging the transverse edges of the sealing member to hold it in position and compress the edges.

The damper is particularly useful for mounting on the end of a crankshaft of an internal combustion engine.

Abstract: A material transporting hose of integral construction having a body of flexible, resilient material which includes a pair of longitudinally reinforced portions disposed on opposite sides of the cross-section of the body. The portions include at least one elongated reinforcing member embedded therein extending generally parallel to the longitudinal axis of the hose to provide longitudinal strength. The longitudinally reinforced portions have a total combined perimeter which is equal to or less than the total combined perimeter of the remaining portions of the cross-section of the hose body which do not contain longitudinal reinforcing members so that at least one-half of the hose remains flexible in a longitudinal direction for ease of handling. The hose structure is particularly useful for long length, fluid transporting hose used in ship-to-shore and ship-to-ship refueling.
