Patent number: 5191670Abstract: A fork scrubber is provided with zigzag bristles for effectively cleaning a utensil such as a fork or the like. The zigzag bristles are mounted within an oval tube into which a fork is inserted. The bristles are oriented perpendicular to the direction of insertion of the fork. As the fork is inserted, the zigzag bristles are pulled within slots between tines of the fork. Where the bristles provide sharp vertex points for scraping the inner edges of the tines. The bristles each have an oblong or rectangular cross-section having wide side surfaces. The wide side surfaces are oriented parallel to the direction of insertion of the fork to provide optimum resiliency. The fork scrubber thus provides a simple, inexpensive, and convenient tool for cleaning forks or other utensils having hard-to-reach places.Type: GrantFiled: December 30, 1991Date of Patent: March 9, 1993Inventors: Ron W.

Patent number: 5181462Abstract: An automatic compactor-crusher for processing spent aerosol spray cans safely depressurizes, evacuates, and crushes cans for subsequent environmentally sound disposal and/or recycling. Fluid residue is safely captured within a reservoir. A vertically upright, supporting frame secured to a floor in the work area supports a telescoping can receiver assembly. The receiver assembly matingly receives cans for processing. A hydraulic crusher assembly located on top of the frame compresses cans against the receiver assembly with an extensible ram. The receiver assembly comprises a tubular sleeve which coaxially receives a displaceable cylinder. A rigid union at the bottom of the sleeve limits travel of the cylinder, and establishes a fluid flow path into a holding tank. A rigid valve guide projecting from the union mounts a fluid control valve for selectively blocking fluid escape from the receiver, and a rigid, canpiercing lance which punctures cans after sufficient ram displacement.Type: GrantFiled: May 6, 1991Date of Patent: January 26, 1993Assignee: Aerosol Disposal Systems, Inc.Inventor: J. Wayne Isaac

Patent number: 5174651Abstract: A continuous, low shear solids dissolution system involving a water supply system (100), polymer metering system (120), mixture feed tank (152), mixture pump (154), mixture transport conduit (172), undissolved polymer dispersal element (188), solution sieve assembly (210), and holding tank (250). The polymer-water mixture (156) is pumped through mixture transport conduit (172). Undissolved particles of polymer encounter dispersal elements (188) and the particles are more uniformly dispersed. Any particles which are carried undissolved out of the mixture transport conduit (172) are forced through sieve (214) to further disperse the polymer in the water. The undissolved polymer is completely dissolved by low shear agitation in a holding tank (250).Type: GrantFiled: March 12, 1991Date of Patent: December 29, 1992Assignee: Gaddis Petroleum CorporationInventor: Preston G.

Patent number: 5174197Abstract: A barbecue device is disclosed, which includes a cooking support member in the form of a slightly concave plate or grid. A support is pivotally connected to the rim of the cooking support member with the support being rotatable from a stowed position, at which the support overlies the upper surface of the cooking support member, to an operating position, at which the support extends downwardly from the cooking support member. A handle is pivotally connected to the rim of the cooking support member with the handle being able to be rotated from a stowed position, at which the handle overlies the upper surface of the cooking support member to retain the support thereon, to an operating position at which the handle extends outwardly from the cooking support member. The handle includes an extension adapted to extend beneath the cooking support member in the operating position, which also acts as a stop against further pivotal movement of the handle.Type: GrantFiled: October 15, 1991Date of Patent: December 29, 1992Inventor: Anthony R. Upton

Patent number: 5158009Abstract: A rack for cooking barbecued ribs includes a plurality of curved legs which generally conform to the shape of the ribs. The legs are welded perpendicularly to a single longitudinal member. A handle attached to the longitudinal member makes it possible to manipulate the rack. The length of the curved legs decreases as the distance from the handle increases, thereby giving the rack a tapered form. Ribs barbecued on the rack cook quickly and evenly due to the improved distribution and concentration of heat.Type: GrantFiled: January 9, 1992Date of Patent: October 27, 1992Inventor: Jeffrey D. Stewart

Patent number: 5156087Abstract: In a machine such as a press having at least one heating platen and one cooling platen, it is proposed to place between the said platens a variable heat conduction device (22a), when the operation of the machine requires a phase of heating the part without the application of pressure, followed by a phase of cooling the part under pressure. This device (22a) has two thermally conductive plates (32a, 34a), normally separated by a space under vacuum (52a) under the action of at least one deformable member (36a), which can be elastic or plastic. The application of the pressure passes the device (22a) from a thermally insulating state to a thermally conductive state.Type: GrantFiled: February 4, 1992Date of Patent: October 20, 1992Assignee: Aerospatiale Societe Nationale IndustrielleInventors: Philippe Cusson, Eric Sixdeniers
