Abstract: A rough and porous coating is applied by spraying and metallurgically bonding to a bearing member. The coating is preferably of a strong and thermally conductive material, such as aluminum-bronze, with the coating having interstices, such as cavities, undercuts, and craters to provide a porous material. An adhesive-solid lubricant formulation is then applied to the coating. The adhesive-solid lubricant formulation fills the coating interstices. The adhesive-solid lubricant formulation is cured for the required time at the required temperature to form a low-friction bearing surface layer.

Abstract: The cageless thrust bearing with unguided cylindrical rollers comprises a pair of thrust bearing races with axially separated flat thrust raceways. Cylindrical rollers all having the same diameter are located between the separated flat thrust raceways. The spacing of the rollers is such that the rollers become radially aligned in the bearing under a rotating thrust load, without side or end guidance of the rollers.

Abstract: A longitudinal lubrication bore extends at least partially through the inner member of a bearing. A radial bore may extend from the longitudinal bore to the raceway on the bearing inner member. A one-way check valve is permanently assembled in the longitudinal bore. The valve permits the flow of lubricant into the longitudinal bore and into the bearing space between the inner race and outer race of the bearing.

Abstract: A high consistency pulp slurry is prevented from floccing by at least one pivotable member located in the vat at the area where the pulp slurry leaves the inlet box and enters the vat. The pivotable member is located with respect to the inner surface of the vat and is structured to speed-up the pulp slurry as it enters the vat to prevent floc formations.If pulp fibers should become stuck in the small space between the outer surface of the pivotable member and the inner surface of the vat, the pivotable member will automatically pivot away from the inner surface of the vat, thereby automatically loosening the stuck fibers. As soon as the stuck fibers are loosened, the pivotable member will return to its initial position.

Abstract: This is an extrusion head for extruding a parison to be blow molded. A shooting mandrel is longitudinally movable within a plastic melt accumulator chamber. After a "shot", the shooting mandrel is in the up position. The plastic melt fed to the plastic accumulating chamber forces the shooting mandrel to the down position as the plastic accumulating chamber is filled. The parison is formed by moving the shooting mandrel upwardly to the up position. The plastic flows around the shooting mandrel as it flows from the accumulating chamber and out of the extrusion head.

Abstract: This knitting needle is a latch needle of the male latch-female hook type. The shape of the groove in the hook and the shape of the latch is such that during the initial use of the needle, only the end of the inner surface of the latch contacts the bottom surface of the groove. The amount of the surface of the inner portion of the latch which contacts the groove bottom surface gradually increases as the groove bottom surface and the inner surface of the latch are worn by use.

Abstract: This is a new hydrofoil structure. The hydrofoil has a radial outer surface having a circumferentially curved portion conforming to and closely spaced from the inside surface of the screen plate. The hydrofoil's radial outer surface also has a flat surface radially inward from the curved portion.The radial outer surface of the hydrofoil is constructed to convey along the flat surface any particles or knots which get in the space between the flat surface and the inner surface of the screen plate.

Abstract: At least one longitudinal baffle extends from an area within the forming zone into the compaction zone. In the forming zone the baffle is pivotally connected to the vat and also has a pivotal structure in the area where the forming zone changes into the compaction zone. Actuating means are located in the compaction zone and apply actuating forces against the outside surface of the baffle to cause the baffle to automatically adjust the convergence angle in response to changes in pulp mat thickness.

The plurality of spray nozzles are arranged along a plurality of vertical planes and a plurality of horizontal planes.The nozzles are located on at least two sides of a central area and are adapted to spray the water to be cooled toward the central area.

Abstract: The roller thrust bearing cage and roller assembly includes an annular cage with a plurality of circumferentially spaced pockets. Each of the pockets is shaped to give proper guidance to the roller when the extended center line of the roller passes through the axis of the annular cage. Preferably each pocket has two radially, inwardly converging sides and preferably, the pockets are trapezoidal. A cylindrical roller is preferably located in each of the pockets.

Abstract: This is a plastic thrust washer strip consisting of a plurality of plastic thrust washers integrally interconnected by thin plastic webs. The plastic webs and integral plastic tabs on each washer of the strip serve to locate and hold the washer strip on the hub of a universal joint.

Abstract: The pressurized screening apparatus for screening fibrous material in liquid suspensions includes a fixed cylindrical screen mounted within a housing to form an inner chamber. An axially extending annular channel receives the suspension. A dilution liquid is passed tangentially into the channel. The dilution liquid helps in the separation of the acceptable fibers from the undesired constituent so that a large proportion of the acceptable fibers is fed through the cylindrical screen and a minimal amount of undesired material flows to the bottom of the annular channel as part of the rejects.

Abstract: The method is performed on a cylinder having at least one end opening for receiving a flange forming tool. An annular shoulder is formed extending from the outside of the cylinder substantially perpendicular to the axis of the cylinder. Also, an annular extension is provided on the cylinder having an outside surface extending from the inside of the annular shoulder to the end of the cylinder. The length of the outside surface is formed to be greater than the radial width of the annular shoulder. A flange forming tool is then applied against the free end of the annular extension to move the annular extension until its formerly outside surface is against the annular shoulder to provide an end flange extending substantially perpendicularly to the axis of the cylinder.

Abstract: A protective guard for a machine tool system including a cutting or grinding member which is movable from a first position wherein access to the cutting or grinding member is barred to a second position wherein the cutting or grinding member is exposed.

Abstract: The body of the needle has at least one lateral opening to relieve stress, absorb shock, and dampen vibrations. The opening or openings are located so as not to extend to the top or bottom of the latch needle body.

Abstract: The drill pipe has a longitudinal section of smaller diameter and a pair of circumferentially separated grooves provided in an annular shoulder adjacent the smaller diameter portion of the pipe. Pipe-holding members to which a pawl is connected are circumferentially spaced adjacent the drill pipe. The pipe-holding members and pawls are simultaneously actuated so that the holding members fit around the smaller diameter portion of the pipe to support the pipe, and the pawls fit into the grooves in the pipe to permit either the breaking out of the pipe string or the making up of the pipe string, depending on which pawl is fitted into the groove.
