Title: Cleaning composition and apparatus for removing biofilm and debris from lines and tubing and method therefor
Inventor: LABIB MOHAMED EMAM
IPC: C11D3/39
Filed: 1998-06-11
Abstract: Biofilm/debris is removed from interior and exterior surfaces of small bore tubing by passing an aqueous cleaning solution of water, one or more surfactants and preferably a hydrogen peroxide source, optionally including small inert solid particles, together with a gas under pressure, to create a turbulent flow within the tubing which loosens the biofilm/debris so it can be flushed from the tubing. When the exterior tubing surfaces are cleaned, the tubing is inserted in a sleeve fitted with an adaptor providing a pressure-tight seal between the tubing and the sleeve. The figure schematically shows an apparatus for cleaning interior and exterior walls of endoscopy tubing: Compressor (100) carries air in line (102) through pulsation control nozzle (104) to mixing chamber (106); air flow is controlled by pressure regulator (108).  Chamber (110) stores cleaning solution, passing it through line (112) to mixing chamber (106), and the resultant turbulent mixture passes through line (114) to adaptor (116) providing a pressure-tight fitting to a port of tubing (120), while line (115) carries cleaning solution to the exterior tubing surfaces.
Patent CA-2295829-A1 (CA)
Title: Self-lubricated bearing
Inventor: HARIG FRIEDRICH
IPC: F16C33/12
Filed: 1998-07-11
Abstract: A self-lubricating bearing (110) is fabricated as a laminate of a metallic substrate (112) and a series of raised structures (113) formed integrally therewith and extending orthogonally therefrom. A fluoropolymer sliding or bearing layer (114) is superposed with the substrate, with the raised structures embedded therein. The raised structures serve to hold the bearing layer in place to help prevent it from sliding along the surface of substrate during bearing operation. This anchorage to the substrate enables a relatively thick bearing layer to be utilized to relatively reduce tendency to creep.  Alternatively, the structures provide a bearing having a relatively thin load bearing layer with a relatively constant friction coefficient over its life, with the structures acting as thermal and electrical bridges for relatively high heat and electrical conductivity between the substrate and a supported article such as a rotating shaft. The structures also may be in direct contact with the supported article to help prevent bedding-in. In this regard, the bearings are provided with a relatively low coefficient of friction, long bearing life, resistance to creep and mechanical stresses, and are electrically and thermally conductive.

Title: Radio transmission method and telephone system, particularly for dect standard
Inventor: BIEDERMANN ROLF
IPC: H04W88/14
Filed: 1998-05-25
Abstract: The present invention relates to a radio transmission method between a transmitter apparatus and a receiver apparatus, wherein said method uses a service channel (area B) for transmitting voice signals and/or data signals as well as a signalling channel (area A) comprising an error correction symbol for transmitting signalling data. When a signalling pause is detected, the transmitter apparatus sends an identification signal for the signalling pauses (P) to the receiver apparatus through the signalling channel. The signals received during the reception of the identification signal for the signalling pauses at the service channel (area B) are not used by the receiver apparatus.  Since the signalling channel includes an error correction, no signal can be reliably transmitted during the signalling pause at the receiver apparatus, thus avoiding the transmission errors that may occur upon transmission in the service channel during the signalling pause or subsequent to the actuation of a mute key.
