Abstract: This invention relates to display apparatus for forming bins to display merchandise or to store objects. A display bin includes means for mounting dividers while maintaining the front panel clear of obstructions. The invention includes brackets attached to the bin for mounting the bin to either vertically slotted rails or horizontally slotted walls. The brackets preferably permit adjustment of the angular orientation of the bin relative to the rails or walls.

Abstract: A shoe patch device and method of preserving and repairing shoes is disclosed wherein a patch member fabricated of a thin, flexible and durable material is formed to be rapidly adhered to the sole and/or upper of the shoe. The patch member is formed in a suitable configuration and includes a plurality of V-shaped notches extending inwardly from its edges to permit the patch member to readily accommodate all shoe sizes and be positioned at differing locations upon the shoe. Due to the lightweight and flexible properties of the patch member, the function and wear characteristics of the shoe are not altered or impaired, nor is it necessary to disturb the original construction of the shoe to effectuate repair or preservation of the shoe.

Abstract: This invention relates to an improved air driven pump for pumping products such as beverage syrups. Two opposed pistons are mounted on a common piston shaft for reciprocal movement within a housing. Cavities corresponding to the pistons are alternately vented and pressurized to intake the product into a pair of cylinders and to drive the pistons to pump the product. A spool valve stem extends into the cavity being vented so that the piston performing an intake stroke moves the valve stem into the other cavity. A pair of axial passages and corresponding side openings in the valve stem provide fluid flow paths for venting and pressurizing the cavities. A valve body biased toward the cavity being vented includes a vent passage for alternately venting the cavities through the side inlets. While one cavity vents, pressurized fluid flows into the other cavity through the corresponding side inlet and axial passage.

Abstract: A truss boom having an extension member equipped with a pulley and a hook, comprising a pyramidal support frame is disclosed.

Abstract: An improved microwave field monitor device is disclosed characterized by use of a microstrip antenna and control electronics adapted to provide a field alarm, field monitor, accumulated dose alarm, and integrated dose indication of RF radiation exposure to an individual. The monitor is packaged in a small configuration similar to an identification badge adapted to be easily affixed to the clothing of a user. The monitor additionally is capable of measuring the RF radiation exposure at particular part or whole body resonance frequency bands or standing wave hot spots known to be hazardous to individuals.
