Abstract: Presented is a portable divider device for dividing the bed of a pickup truck into smaller compartments so that material, such as groceries, deposited in the smaller compartments do not spill all over the bed. The divider device is particularly applicable on trucks on which there is a camper shell of the type that encloses the entire truck bed, leaving only an access door at the rear of the truck which may be opened to place material to be carried in the back of the pickup bed near the tail-gate. The problem is that unless the grocery bags or other materials, are supported in some way, the first time the brakes are applied, the grocery bags fall forward and all of the groceries are scattered all over the truck bed. My divider provides a flat support plate that extends across the bed of the truck and abuts against the wheel well which projects into the bed of the truck.

Abstract: An improved inertia sensitive seat hinge mechanism which enables the seat back to be normally folded forwardly to permit access to a motor vehicle rear compartment area which locks when exposed to a predetermined acceleration load. The inertia sensitive actuator is in the form of a generally straight lever which is mounted for rotation to the upper hinge structure. A projecting finger of the inertia sensitive pendulum interacts with a cam surface associated with the lower recliner structure to maintain the inertia device in an engaged position when the seat back is in its rearmost folded position. This positioning improves reliability of the hinge device. The configuration of components according to this invention eliminates the objectionable rearward projection presented by many present seat hinge designs which can interfere with free access to the rear compartment area.

Abstract: An integrated pressure exhaust valve and pneumatic coupling is used on a truck trailer for bringing air brake pressure from a tractor to the truck trailer. A gladhand coupling moiety is used for quick connection with an identical coupling moiety on the air pressure hose from the tractor. A check valve mechanism is incorporated in the body of the trailer coupling moiety for permitting air flow to the brakes when pressure from the tractor is greater than pressure in the trailer brake lines, and for permitting air flow from the brake lines to the atmosphere when pressure from the tractor is decreased. The integrated pressure exhaust valve and pneumatic coupling moiety can be mounted on the front of the trailer where it is found that pressure exhaust valve placement is most effective.

Abstract: A polarizing cube beamsplitter, which is designed for infrared applications, comprises two 45.degree. prisms made of ZnSe. A first anti-reflection layer, which is a Herpin equivalent layer consisting of the triad of sublayers ZnS-ZnSe-Zns, is deposited onto the hypotenuse of a first one of the prisms.

One layer in each pair of thin-film layers in the polarizing stack is a Herpin equivalent layer consisting of the triad of sub-layers Te-ZnSe-Te, and the other layer in each pair is a thin film of ZnSe. A layer of prism material ZnSe, which is thick enough to be optically polished, is then formed on the second anti-reflection layer. The hypotenuse of the second prism is likewise optically polished, and is pressed onto the optically polished layer of prism material to form a bond. The resulting beamsplitter is of cubic configuration.

Abstract: An optical waveguide is established near the surface of a body of bulk, optically transparent, crystalline material (12) by depositing and bonding a thin layer of material (16) that undergoes an irreversible structural transition under annealing such as silicon nitride or silicon oxide on a surface of the bulk crystalline material (12). The assembly is then heated to change the state of the thin layer and produce stress on the order of 10.sup.10 to 10.sup.11 dynes per square centimeter or more. Open guideways or breaks (22, 24) are then formed in the thin layer (16), thereby establishing optical stress waveguides (32, 34) in the bulk crystalline material (12), just under the open guideways. The bulk crystalline material is then employed for modulation, detection or in other interactive processes with respect to optical signals applied to the waveguide.

Abstract: To a carrier (1, 1') there is cemented a bar of a material (3, 3'), for example glass or a ceramic material, which is subsequently divided, using cuts (7, 7') which extend transversely of its longitudinal direction, into a number of slices (9, 9') which are separately cemented to the carrier. Each slice (9, 9') is provided with a groove (13, 13') which extends parallel to the cuts (7, 7'). The grooves (13, 13') are curved and have a center of curvature which is situated at the side of the bar (3, 3') which faces the carrier (1, 1'). In the grooves (13, 13') there are secured optical fibres (19, 19') which follow the curvature of the groove, after which a side portion of the fibres which is situated furthest from the carrier (1, 1') is ground off. A flat ground face (21, 21') is thus formed one each fibre (19, 19'). Such ground fibres (19, 19') are arranged so that their ground faces contact one another in order to form directional couplers, after which the slices (9, 9') are detached from the carrier (1, 1').
