Abstract: Exercising apparatus includes a collapsible frame having upper and lower tracks supporting upper and lower groups of pulleys and moveable upright track supporting risers. The upper pulleys support an adjustable friction block partner supporting harness adjacent the frames front end, and a line extending from the friction block over upper pulleys to a coupling transmits a friction block enhanced force related to the partners weight. A multiple path pulley arrangement joined to the coupling provides a mechanical advantage, reducing by a multiple the effective force delivered adjacent the frame's back end to an exercising bar spaced apart from the exercising partner through lower track coupled pulley blocks. A separate line from the upper track passing through an offset pulley, is extendable to the lower lines to allow for pull down exercises.
Abstract: Multiple simultaneous envelope duplicating apparatus has a windowed feed elevator supplying envelope stacks to an offset duplicator. The elevator has an open frame supporting a pair of spaced apart parallel envelope stack supporting plates. The plates and the frame define windows for receiving in vertically movable relationship, guide members to maintain the envelope stacks upright and in alignment with suction feet at a receiving station of the offset duplicator. A delivery end of the duplicator having a receding stacker also has an open frame supporting a pair of spaced apart envelope stack supporting plates to receive printed envelopes, and define windows for receiving in vertically movable relationship, a second set of guide members to maintain the printed envelope stacks upright. Upright member supporting bases are adjustable so that the guide members can be fitted to bound the sides of different sized envelopes. Bulk envelope chargers have envelope receiving side plates and a back retaining plate.
Abstract: An emergency lighting fixture has a capped circular and longitudinally slotted tube containing a power supply and charging electronics. Cylindrical outer envelopes rotatably enclosing the tube each have pivotally mounted lamp shells at opposing ends. A spider plate attachable canopy having integrally molded apertured inner lugs has an outer integrally molded arm supported overhanging portion, the arm being of substantial cross section for supporting the tube weight centrally supporting the lighting fixture. The tube has a longitudinal support slot receiving a rectangular support piece terminating from the canopy arm. End caps enclosing tube ends each have a circumferential groove for receiving guide nubs are disposed in spaced apart relationship on the inner circumference of the envelopes. The envelopes have oblique truncated surfaces allowing beam positioning without envelope interference.
Abstract: A two reflector microwave antenna has a concave focusing main dish having an integral peripheral flange. An integral radome shell also having a peripheral flange is disposed in confronting relationship to the main dish flange. Mounted over both flanges is a clamping ring to keep the main dish and radome shell in a stress condition of fixed edge shells. A secondary reflector is provided on a central portion of the radome. The concave focusing main dish in one example, defines a paraboloid of revolution. Specific shapes of the main dish and the radome shell are selected to appropriately focus the microwave radiation. A radome portion of a variable thickness of dielectric material of the integral radome shell modify the path of microwave energy compensating for diffraction of induced edge spillover. The stress condition of the shells as maintained by the clamp about the flanges provides a structually rigid antenna substantially void of structural elements.
Abstract: Large format photographic apparatus for creating the illusion of vehicle motion has a winch frame for supporting a cable arrangement and for simultaneously pulling two separate cables. A first cable is coupled to a subject vehicle to be photographed. The second cable is coupled via a linkage translator to a moveable platform mounted camera cart. The platform has a pair of spaced apart rails having inwardly facing surfaces and the cart has laterally disposed resilient wheels engaging the rails whereby transverse vibrational motion is reduced. Beyond the subject vehicle is an upright triangular weight bearing structure. A separate cable coupled from the rear of the vehicle being photographed to the weight balances and maintains an inertial drag on the vehicle to smooth out the motion of the cable of the vehicle. Similarly a separate cable coupled from the cart is coupled to a different upright triangular weight bearing structure.
Abstract: A modular room divider system has plural upright juxtaposed panels having cylindrical anchor receiving apertures disposed about upright axes in the panels top and bottom surfaces. A coupling assembly has a pair of spaced apart anchors mating with the anchor apertures. Threaded portions having opposingly directed right and left hand threads extend inwardly from the anchors and are centrally engaged by an internally threaded sleeve having adjacent right and left hand threaded portions. The sleeve has a square prismoidal exterior surface and is traverseable by a notched wheel having a mating central aperture. A channel extends from the anchor apertures to the edge of each channel.In use, two panels are assembled by placing them in juxtaposition. The coupling assembly is placed in alignment over the panels, the anchors being lowered into the anchor apertures and the threaded portions over corresponding channels.

Abstract: A peristaltic pump has facing half shells defining a pumping cavity and circular tube access grooves entering the cavity. Rotor apparatus includes a cylinder having concave, semi-spherical end surfaces rotatably supporting roller balls therein. The pumping cavity has a tube supporting substantially semi-annular, semicircular seat. Spring loaded roller bearings in rotor axial bores communicate with the roller balls adjacent the concave surfaces. The roller bearings engage the roller balls urging a central crescent shaped occlusion of the tubing.In operation, tubing is inserted in the access openings. The impeller rotation and frictional forces transmitted by the roller balls forces the tubing about the semicircular seat and out the opposing access groove. The roller balls impinge the tubing normal to a nominal tube axis to cause an occlusion deforming the tubing to a crescent configuration.
Abstract: A geothermal space conditioning and water heating system for a building structure comprises a battery of serially coupled thermal storage wells. Each well includes a dual concentric thermal conduction tube having an external circumference and an integrated earth interface and substantially moisture impervious clay platelet transition surrounding and at least double the tube circumference. The thermal storage battery has a cold port and a hot port maintained at a temperature greater than the cold port. A space conditioning arrangement is provided in which thermal transport fluid passes through a fan-driven radiator. A reversible heat pump has a radiator conditioned air coupled first heat exchanger and a downstream radiator fluid coupled second heat exchanger. A second heat pump has a first heat exchanger in thermal communication with a hot port coupled hot water heater and a cold port coupled second heat exchanger. A transient storage tank provides a time averaged uniform transport fluid temperature.
Abstract: A device for dispensing an iron oxide based powder makeup includes a hinged thin compact case and an annular module joined to the case interior. Extending across the module, a transverse portion divides the compact into first and second regions. An apertured cover encloses the first region, confining an iron oxide powder makeup therein. A plate mounted cork surface in facing relationship to the cover sparingly receives the iron oxide powder through the aperture array. The cork surfaced plate is coupled to the transverse portion of the module by a live hinge. Plate latches are provided for securing the plate in a first position flush to the cover, and a second position, providing access to the powder adhering cork surface.
Abstract: A peelable human nail coating system comprises a water emulsion of polymer resin stabilized with partially acetylated poly vinyl alcohol. The resin includes poly vinyl acetate homopolymer and poly vinyl acetate-ethylene copolymer. The composition is applied in a thin area coating drying rapidly upon exposure to air. A water impermeable clear plastic container has a restrictive wiping aperture for removing excess composition on an applicator stem to prevent dripping from the stem and caking. The composition is applied to human keratinous surfaces with a liquid absorbing applicator. After drying the coating may be removed by lifting the film at the cuticle and slowly pulling backward toward the tip of the nail. The composition is substantially odor free, contains no drying organic solvents, is generally non-toxic and non-flammable.
