The preferred lens segments have a thickness of about 1.0 mm or less and comprise an optical material having an index of refraction of 1.5 or more.

Abstract: A device for securing a coffee filter in a coffee maker basket comprises a contractable annular member expandable for urging the coffee filter against the inner side of the basket to prevent coffee grounds from slipping between the filter and the side of the basket and into the coffee.

Abstract: An improved percussor assembly comprises a rigid body member having gas inlet and gas outlet means, the latter including a restricted passageway and an enlarged passageway, and a vent passageway communicating with the enlarged portion adjacent the junction of the restricted passageway whereby atmospheric air is entrained into the enlarged passageway as gas flows therein from the restricted passageway thereby increasing the volume of gas supplied to a remote applicator while economizing on the amount of pressurized gas required to operate the percussor. The vent passageway also relieves gas pressure from a remote pneumatic applicator between successive bursts of gas from the percussor assembly. An improved remote applicator having means for selecting the force of the percussive bursts is also provided.

Abstract: An improved oxygen concentrator assembly includes a microprocessor and cooperating means for monitoring or sensing functions and performance of various components of the concentrator. A test apparatus having means for selecting any of the functions monitored by the microprocessor is connected to the concentrator and displays the selected monitored functions for diagnosing performance levels and component problems or failures.

Abstract: A base stock composition comprises a blend of gilsonite, asphalt and a rubber latex residue. The base stock may be used alone as a paving material or emulsified to form a gilsonite emulsion having a variety of uses.

Abstract: An electrical box designed to minimize the potential for sound, smoke or fire traveling therethrough when wall-mounted and has an interior rigid housing and a molded non-combustible exterior casing. The casing is a unitary, single-piece sheathing, having openings only for attachment of line conduit. A tubular collar portion extends outwardly from the front opening of the box, and is easily cut or machined to conform to the adjacent wall surface.

Abstract: A heated stadium cushion has a pad having a pocket adapted to contain an air-activated chemical heating packet. A second pocket contains weather-resistant clothing, such as a poncho. In another embodiment a slipcover is provided for enclosing a conventional seat cushion, the slipcover having an enclosed pocket for the heating element.

Abstract: A flexible, transparent plastic book cover has a pocket portion attached to the front cover portion containing various pages or a booklet containing emergency medical information. The book cover is particularly adapted to fit telephone directories of any thickness. The book cover has a front cover section having a pocket to slide over the front cover of a phone book, and a rear cover section having a sleeve for slidably receiving the back cover of a phone directory. The third section, which is hingedly attached to a forward portion of the front cover section and extends rearwardly therefrom, is adapted to mount a booklet containing medical information.

Abstract: An improved nebulizer for directing an aerosol from a spray orifice toward an outlet pipe against a target comprises a convex target surface substantially enlarged relative to the diameter of the spray orifice and a cylindrical hood coaxially surrounding said target having a single open port coaxial with said spray orifice, the spray orifice including means for forming an inverted aerosol cone all of which first impinges against the target, and whereby substantially all of the aerosol must exit from the cavity through the single open hood port.

Abstract: An improved percussor assembly comprises a rigid body member having gas inlet and gas outlet means, the latter including a restricted passageway and an enlarged passageway, and a vent passageway communicating with the enlarged portion adjacent the junction of the restricted passageway whereby atmospheric air is entrained into the enlarged passageway as gas flows therein from the restricted passageway thereby increasing the volume of gas supplied to a remote applicator while economizing on the amount of pressurized gas required to operate the percussor. The vent passageway also relieves gas pressure from a remote pneumatic applicator between successive bursts of gas from the percussor assembly. An improved remote applicator having means for selecting the force of the percussive bursts is also provided.

Abstract: An oxygen concentrator having molecular sieve beds for selectively adsorbing nitrogen from atmospheric air for increasing the oxygen concentration of a product gas, a reservoir for receiving the product gas, a compressor for charging atmospheric air to the sieve beds and a valve and valve switching means for directing atmospheric air from the compressor to alternate sieve beds includes means for sensing the withdrawal rate of product gas from the reservoir and a microprocessor provided with the minimum time required for charging the respective sieve beds to achieve a product gas having a selected oxygen concentration at the sensed rate of withdrawal and means for switching the valve to charge the beds for the minimum charge time.

Abstract: A nail-removing hammer has at least one sidewardly opening claw located just behind the poll portion of the hammer head. The claw is formed from a transverse bore in the side of the head, and a pair of jaws at the top of the head which are situated over the bore. The jaws are preferably defined by V-shaped flanges extending over a portion of the bore. Similar sidewardly opening claws may optionally be mounted in the throat.

Abstract: An improved process for recycling asphaltic concrete comprises introducing asphaltic concrete particles at one end of an elongated rotating drum while supplying flame and hot gases of combustion to the drum at the opposite end, and introducing virgin aggregate into the drum intermediate the two ends. The asphaltic concrete is heated as it travels along a portion of the length of the drum and is recovered just prior to reaching the position along the drum length at which the aggregate is introduced. The aggregate is heated as it travels toward the end of the drum at which the flame and hot gases are introduced. Heated aggregate may be returned to the drum for further heating, and may be directed to the opposite drum end and mixed with the asphaltic concrete in a section of the drum.

Abstract: A purified water storage system for a reverse osmosis purification unit has a container containing an interior chamber defined in part by a flexible wall member, such as a bladder or diaphragm, for receiving and containing purified water. A second chamber for containing pressurized air exists on the opposite side of the flexible wall member. The second chamber is at least 75%, preferably 80%, and still more preferably 100% of the maximum volume of the water-containing chamber.

Abstract: A portable descent device for lowering an object at a controlled speed has a rotating spool carrying wrapped cable mounted within a casing. The spool rotates about a fixed shaft in a sealed chamber containing a viscous liquid. A series of alternating, closely adjacent, flat, parallel, rotatable and non-rotatable discs are mounted in the sealed chamber and extend radially of the shaft. As cable is payed out from the device, movement of the rotatable discs through the fluid creates a frictional drag which slows the descent rate to a relatively constant, safe speed.
