Abstract: Abstract of the Disclosure A photographic film unit with lateral and transverse edges having a pair of sheets connected in superposition with a photosensitive layer located between the sheets.  A container carrying a quantity of fluent processing composition is arranged to provide for the discharge of the composition to between the sheets,  The improvement comprises an integral intermediate sheet disposed between the pair of sheets and coupled to both of them at the lateral marginal portions thereof and separating such lateral marginal portions of the, sheets by a predetermined amount.  A portion of the inter-mediate sheet extends from between the pair of sheets at one end thereof and is secured transversely to one of the sheets at that end and is folded away from that sheet over itself within the compass of that sheet to define a compart-ment for fluent processing composition.  The intermediate sheet has a centrally disposed exposure aperture and lateral edges which are in register with the lateral edges of the other sheets.  The outer portions of the lateral edges of the intermediate sheet have a greater thickness than does the boundary of the aperture.  The differing thicknesses of the intermediate sheet may be formed by machining a portion of the sheet which is originally of the thickness of the lateral edges, or by the utilization of separate spacer rails at the lateral edges.

Abstract: ABSTRACT OF THE DISCLOSURE             A vehicular pneumatic tire which, except for head cores, is composed solely of an elastomer blend strengthened by molecular orientation.  The blend is a mono-olefin copolymer rubber with a polyolefin and sufficient curing agents to affect vulcanization when the blend is subjected to heat and pressure.  The process for making the tire comprises performing an annulus of the elastomeric blend with bead cores and adjacent the edges, the diameter of the preform being essentially that of the bead diameter of the completed tire and the axial distance between the beads less than the transverse arcuate dimension of the completed tire.  The preform is cured and while still hot following curing, is stretched and shaped to final size and the gener-ally toroidal form characteristic of conventional pneumatic tires with resulting biaxial molecular orientation, which orientation is retained in the tire by cooling it below the melting point of the polyolefin before removing the tire from the mold.

Abstract: ABSTRACT OF THE DISCLOSURE           The specification describes  a modulating pump including a pumping member that is initially operable by a solenoid device in a relatively long full-stroke condition to effect rapid pressure build-up of the fluid supplied to a load, the pumping member being subsequently operated by the solenoid device in a relatively short stroke condition to effect further pressure build-up in the load. A main spring device normally bias the armature of main solenoid device to achieve the full-stroke operating condition, and when the pressure of the load reaches a value to cause the return force of the main spring to be overcome, a resilient abutment device becomes operable to achieve the desired short stroke pumping condition.  A self commutating pump device is also disclosed.  The modulating pump device is included in a vehicle traction control system, as, for example, an anti-skid traction control system for automatically braking an overrunning driven wheel relative to another driven wheel connected thereto by a differential mechanism.

Abstract: ABSTRACT OF THE DISCLOSURE           A bridge which has a bridge deck constructed of corregated checkered metal plate and which is supported by a plurality of side-by-side box beams carried by spaced apart beam supports.  The box beams have upright sides which are connected to upper and lower chord plates all of which are constructed of corrugated plate having corrugations which run parallel to the length of the box beams and which have a large corrugation pitch and depth.  The chord plates and sides are bolted together at spaced apart intervals.  Thin-walled shear plates are placed against the box beam sides and bolted  to the corrugation troughs of the sides and they carry vertically acting shear loads while their con-nection to the box beams prevents them from buckling.  A concrete layer is poured on top of the bridge deck so as to form a mechanical interlock between the concrete and the deck to thereby structurally integrate the concrete layer with the remainder of the bridge.   A longitudinal camber can be incorporated in the box beam.

Abstract: ABSTRACT      A device for arresting the growth of a rip in reinforced flexible sheet material, for example elastomeric sheet material reinforced with woven nylon fabric, comprises a flexible sheath member having a flexible core member extending throughout its length and chemically bonded thereto.   The sheath member includes tensile load path discontinuities at intervals along the length of the core member and at least in regions of the sheath member remote from the core member. The tensile load path discontinuities prevent tensile loads being transmitted along the length of those regions of the sheath member which are not bonded to the core member, such loads being diffused into the core member because of the bond between the sheath member and the core member.   A number of these devices may be attached to an air cushion vehicle flexible skirt assembly manufactured from sheet rubber reinforced with woven nylon fabric so as to arrest the growth of rips which may propagate during operation of the vehicle.
