Abstract: A face seal with hydrodynamic thrust pads assembly is provided. The assembly comprises a ring structure with a front side facing in an axial direction that has a seal face continuous about the ring structure and a plurality of cut-outs with concave surfaces spaced concentrically around the seal face. A plurality of elastomeric laminates having a convex side are disposed in the concave surfaces. A plurality of thrust pads are bonded to the laminates such that one side of the thrust pads are all in a plane parallel to the plane of the seal face. When a closing load is transmitted against an opposing member by the sealing pressure against the back face of the assembly while the opposing member rotates relative to the assembly, friction and pressure forces cause the thrust pads to swing about a pivot point located towards the opposing member such that the fluid film converges in the direction of movement of the opposing member. Simultaneously, the seal face seals against the opposing member.

Abstract: Radiographic elements and assemblies are disclosed. The radiographic element has silver halide emulsion layer units coated on opposite sides of a film support, and are constructed to minimize crossover during exposure by the intensifying screens. The minimal crossover radiographic elements record both bone and soft tissue structure because a silver halide emulsion layer unit on one side of the support is chosen to exhibit an emission and contrast exceeding that of another silver halide emulsion layer unit on the opposite side of the support. Radiographic assemblies consisting of the radiographic elements and various front and back intensifying screens produce clear and useful X-ray images of the various bones and surrounding soft tissue structures of the body.

Abstract: The invention describes silver halide packet emulsion grains or crystals that are conventionally precipitated using gelatin of a given isoelectric pH, surrounded by a layer of gelatin-grafted-polymer particles wherein the grafted gelatin has a different isoelectric pH and the said gelatin-grafted-polymer particles are optionally chemically bonded to the gelatin surrounding the silver halide microcrystals. Such packet emulsions can form the basis for a mixed-packet color photographic system.

Abstract: A rolling member which has improved strength and permits stable formation of oil films between its rolling surface and its mating surface and which shows a long life even under unfavorable lubricating conditions. The surface of the rolling member is subjected to heat treatment while nitriding. The rolling member is then treated to form minute recesses in its surface so that such surface has a surface roughness parameter RMS of not less than 0.10 .mu.m and a negative SK value. Thus, the surface strength of the rolling element increases and the oil film forming rate improves. The surface of the rolling member is less likely to suffer peeling damage and wear. Its life is prolonged.

Abstract: A pull-out guide for a drawer includes a support rail to be mounted on a side of a furniture body or carcass and a pull-out rail to be mounted on the side of the drawer. Guide members such as rollers transmit the load of the drawer and are mounted on the rails. The rollers of the support rail and of the pull-out rail are offset perpendicular to the direction of pulling out the pull-out rail relative to the support rail. The pull-out rail thus is guided on two tracks. The pull-out rail has at least one horizontal tab which projects below a running web of the support rail and forms a lift protection preventing the pull-out rail from being lifted off the support rail.

Abstract: In a recursive distributive sort of records according to their key fields, a method for distributing keys to form one or more subgroups and collecting them to preserve or maintain an order among the subgroups. The distribution is accomplished by comparing each key field against an extrinsic attribute and then assigning the key to a subgroup or bucket. The collection sequence preserves the overall key field order. A Dynamic Branching Table (DBT) for governing the ordering of buckets during the collection phase is initially populated with NO-OP instructions. During the distribution phase, a CALL instruction replaces the NO-OP in the sorted order DBT position upon the first occurrence of a distinguishable character in the key character sequence being scanned. An address pointer, pointing to the corresponding bucket, is then inserted in a Bucket Pointer Table (BPT) indexed to the DBT.

Abstract: A pressure reducing valve with a breathing hole is incorporated in a dome provided on the upper wall of a fuel tank and it is open to a vent pipe. A fuel cut valve with a leak hole is provided proximately to the pressure reducing valve. Opening-closing means are also provided on the port side of the fuel cut valve so as to actuate both the pressure reducing valve and the fuel cut valve. When an engine is running, the pressure of return fuel is applied to a float of the opening-closing means, whereby the pressure reducing valve is opened and the fuel cut valve is closed. When the engine is stationary, due to no pressure of return fuel, the float goes down to close the pressure reducing valve and open the fuel cut valve.
