Title: Suction cup for use in windows
Inventor: ADAMS WILLIAM E
IPC: F16B47/00
Filed: 1991-07-29
Granted: 2002-01-22
Abstract: An improved suction cup (110) made of a light transmissive material is provided having a head (112) and a cup portion (114) a concave interior surface adapted to contact a window and an exterior surface opposite said interior surface. A ridge (118) of material is provided along the outer portion of the exterior surface, so that, when the suction cup is in a sealing position, the ridge of material is generally parallel to the mounted surface.      In such an arrangement, light (130) passing through the ridge (118) of material continues in a straight path (134) and does not converge at a focal point (140).      Alternatively, surface deformations, such as grooves (218), circular ridges (216), dimples (318), and roughing, may be provided on the exterior surface of the suction cup. These surface deformations diffuse the light passing therethrough, preventing all of the light from converging at a focal point.

Title: Method and apparatus for anaerobic sludge digestion
Inventor: CLARK SIDNEY E
IPC: C02F3/12
Filed: 1992-03-11
Granted: 1997-11-25
Abstract: Method and apparatus for anaerobically digesting sludge by filling an anaerobic sludge digestion vessel having a top and bottom and a substantially vertical draft tube with an upper end spaced downward of the vessel top and a lower end spaced upward of the vessel bottom, with liquid sludge to a level substantially above the draft tube upper end; feeding a pressurized stream of liquid sludge to the inlet side of an upwardly directed jet nozzle operatively positioned and in communication with a substantially vertical venturi tube having a lower inlet and forming part of the draft tube lower end to a lower pressure thereby creating suction at the venturi tube inlet and producing a pumping action which causes a stream of liquid sludge in the vessel bottom space to flow into and upwardly in and out of the draft tube upper end and to thoroughly admix and disperse with the pressurized sludge stream supplied to the jet nozzle and also causing downward circulating flow of liquid sludge in the vessel.  Additional sludge mixing can be achieved by placing a similar jet nozzle and venturi tube at the top of the vessel to produce a downward mixing flow of sludge in the draft tube.  Also, such a jet pump can be mounted substantially tangentially of the vessel wall to produce helical mixing of the sludge in the vessel. The driving liquid fed to the jet nozzle can be partially digested sludge withdrawn from the vessel, raw sludge or a mixture thereof.

Inventor: DEVAUX FRANKLIN
IPC: E05G5/00
Filed: 1990-07-17
Granted: 2001-04-10
Abstract: The invention concerns a system for protecting documents or valuables, particularly articles such as bank notes, cheques or bank cards enclosed in at least one physically tamper-proof container, i.e a small box (1) which, in the event of being attacked, destroys them using suitable means, the system being characterised by the fact that the operating cycle of the small box (1) comprises a limited number of logical states, called modes, the transition from a first to a second mode being the consequence of a specific event, the licit nature of which is ascertained by a suitable and autonomous method able to be communicated to the small box (1), the transition then being accompanied by the small box's loss of memory of its previous mode. The present invention is particularly for use in the protection of documents or valuables, especially bank notes, cheques, bank cards, or even dangerous medicines (drugs) or those with a considerable added value. Protection is guaranteed both inside a bank (or chemist's, etc.) and during the transportation from the bank to another branch.
