Title: Office size instrument sterilization system
Inventor: SIEGEL NORMAN L
IPC: A61L15/46
Filed: 1992-01-02
Granted: 1999-03-30
Abstract: The  body  portion  (A)  of  a  small  portable sterilizer has a face panel (46) against which a door (B) is selectively closed.  The face panel defines an access opening for a sterilization chamber (10) which receives a cassette  (C),  an access opening for an anti-microbial concentrate chamber (20) which receives a powdered or other sterilant concentrate, and an outlet opening (50) from a microbe filter which filters microbes from incoming rinse water.   The face plate and the door define fluid flow channels (48, 52) therebetween for selectively directing sterilant solutions and rinse solutions among the anti-microbial concentrate chamber, the sterilization chamber, and the microbial filter. The cassette is configured to assure that it is inserted into the sterilization chamber with  a  unique  orientation  such  that  its  fluid  inlet apertures  (114)  and  outlet  apertures  (124)  are  at preselected locations.   The door includes generally U-shaped projections (116) which abut an outer surface of the cassette in the sterilization chamber partially surrounding the fluid inlet apertures.  The U-shaped projections assure that the cassette is seated in the sterilization chamber and provide a well which directs the circulating fluids into the cassette inlet apertures.  A pair of gaskets (56, 86)  surround the active portion of the face panel.   A vacuum pump (90) selectively draws a vacuum in an annular region (88) between the gaskets, which vacuum locks the door against the face plate in a sealed, closed position. To assure a fluid tight seal, the gaskets are O-rings which are pressed by the vacuum into V-shaped grooves (82, 84).

Abstract: An arrangement for enclosing a branch-off between a pair of cables (2, 3, 4) comprises a dimensionally recoverable sleeve (5) which can surround the branch-off, and one or more clips (6) which can be positioned about opposed walls of the sleeve to divide the sleeve into channels for the cables. The or each clip (6) is of unitary form and has a pair of legs (8) that are splayed outwardly to facilitate positioning of the clip over the sleeve walls. The or each clip is deformable so that the legs can be forced towards each other after the clip has been positioned on the sleeve walls but is sufficiently rigid, at least in its deformed state, it will resist opening out of the legs under the recovery forces of the sleeve.  The invention provides a relatively simple and easy to install enclosure for branch-offs in harnesses for example that are intended to be used in automotive vehicles.

Abstract: A system for controlling a thickness of a strip being rolled by a rolling mill having more than two rolling stands, in tandem configuration. A subcontrol unit controls a rolling speed and a rolling load of a final rolling stand according to a predetermined control schedule. A plurality of tension gauge units installed between adjacent rolling stands detect a tension of the strip.  A plurality of thickness gauge units including at least first thickness gauge unit installed on the output side of a first rolling stand, second thickness gauge unit installed on the output side of a penultimate rolling stand, and final thickness gauge unit installed on the output side of the final rolling stand, detect a deviation in the thickness of the strip from a predetermined value.

Granted: 1995-09-19
Abstract: A communication system (100) is provided comprising a communication resource controller (110) wherein the likelihood of success for establishing synchronous digital communication with a communication unit (120) is substantially greater than the likelihood of success for establishing analog communication. The communication unit may establish analog communication after the communication resource controller receives a digital access code from the communication unit. The analog communication is deferred until the received signal strength from the communication resource controller is above a predetermined level which makes the establishment of analog communication substantially likely.

Title: Multicast communication tree creation and control method and apparatus
Inventor: AUERBACH JOSHUA SETH
IPC: H04L12/18
Filed: 1993-04-20
Granted: 1998-07-14
Abstract: In a multicast network communication system, administration of the communication path making up the multicast tree itself has been separated from control and administration of the network.  Creation of a multicast distribution tree and control over the membership thereof, is separately controlled independently from the creation and use of the tree transmission path used to communicate among the members of a multicast set.  Transmission distribution trees are set up when a transmission request is received and the properties of the transmission path that is required are known.  Transmission paths are created and controlled by all nodes in the communications system, each node having necessary control code and processors for responding to requests from set members to transmit a message to groups of users by creating and activating the necessary tree communication path distribution linkages.   A distribution tree is created by the Tree Leader by generating a tree address using a random number generator.  A tree address correlator is generated utilizing network and node identifiers unique for the network, and a list of subnodes or users connected for each member of the multicast tree set is generated.  Using this information, a tree distribution path is computed to cover all of the subnodes required and a tree set up request message is sent by the Tree Leader along a computed path to each involved subnode.  Each subnode returns a message indicating whether the tree address is already in use or is available for use.  Successfully negotiated tree addresses are marked at the path link initiation and termination points at each node through the network.
