Title: Surge arrester with spring clip assembly
Inventor: SMITH ROBERT W
IPC: H01T4/00
Filed: 1993-06-14
Abstract: ABSTRACT     A  surge  arrester particularly suited  for  secondary  side protection of distribution transformers, includes a low-voltage, high-energy varistor disk having electrodes disposed about its facing surfaces and a self-compressing spring clip with spring arms disposed about the varistor to provide the compressive force necessary  to  maintain  good  electrical  contact  between  the electrodes and the varistor.  The arrester includes terminals for electrically interconnecting the electrodes with the electrical apparatus being protected by the arrester.  The arrester further includes  a  dielectric  coating  substantially  enveloping  the varistor, the spring clip and electrodes.  The arrester requires no other housing.   The spring arms may be made in a variety of configurations and shapes and may be interlaced with adjacent spring clip and varistor subassemblies so as to form three-phase or other multi-pole arresters.  A particular preferred embodiment of a multi-pole arrester includes two or more varistors and a spring clip having a central base member and two spring arms.   The spring arms form lobes disposed one on either side of the base member, and the base member and spring arms are all integrally formed from a single piece of material.   c:\dlh\d\cooper\surge.pat

Abstract: The present invention relate to a melt down composite feather and/or down wadding and its producing method and equipment.  The problem of forming, fixing, sewing and cutting out the feather and/or down material is successfully solved.  By application of the invention, the feather and/or down characteristics of thermal insulation, softness and tensile strength are much improved. The invention belongs to  melt blown nonwovens field.      The main idea of the present invention is described as the following. The molten polymer is extruded and blown out of the die heads by high-velocity hot air to form two or more layers of melt blown fiber webs. The webs tend to extend to join together and a certain angle B exists between the extending directions of the webs. In the same time, the pre-equalized feather and/or down  is blown out of down slot jet positioned between the die heads in the laminated state and sandwiched and wrapped by the melt blown fiber webs.  Said fiber webs and said feather and/or down blown out of the feather and/or down slot jet twine and stick together randomly and they are condensed,  and collected on the receiving device to form the melt blown composite feather and/or down madding.

Title: Method for point-to-point communications within secure communication systems
Inventor: BANWART DEAN E
IPC: H04L9/14
Filed: 1994-06-16
Abstract: A Method For Point-To-Point Communications Within Secure Communication Systems Abstract of the Disclosure In a secure communication system (100), a secure point-to-point communication may be accomplished in the following manner.  A first communication unit (102) receives a request from an operator for a point-to-point communication identifying at least one destination communication unit (103).  In response, the first communication unit generates a private call key variable by modifying an encryption key variable through the use of a predetermined function.  Identity of the encryption key variable and information pertaining to the predetermined function is transmitted by the first communication unit to the destination communication unit.  Upon receiving the identity of the encryption key variable and information pertaining to the predetermined function, the destination communication unit generates the private call key variable.  When the private call key variable has been determined by the first communication unit and the destination communication unit, both communication units can engage in the secure point-to-point communication.

Title: Method and Apparatus for Telephone Prize Opportunities
Inventor: KASDAY LEONARD R
IPC: G07F17/32
Filed: 1994-08-18
Abstract: A telephone network is modified so that callers making telephone calls can engage in a game of chance to win a prize without having had to specially dial the game processor, i.e., the telephone numbers of the telephone calls are independent of the game processor. In one embodiment of the invention, the game processor is part of the switch that processes calls through a telecommunications network. Upon conclusion of the game, the caller is supplied with an indication as to whether or not he is a winner and will receive a prize. The determination that acaller is a winner need be made only if the call was successfully completed, that is, routed to a destination at which the call is answered. Advantageously, a) games of chance are attractive to people, especially when it costs nothing to enter, b) the determination that a caller is a winner can be immediately conveyed to him, and c) by proper selection of the odds of winning and the value of prizes, the game can be arranged so that its cost to a telecommunications carrier is less than that carrier's present discounting program.

Patent CA-2148950-A1 (CA)
Inventor: CHEN XIAOQIANG
IPC: H04L12/56
Filed: 1995-05-09
Abstract: An apparatus and method is described for multicasting an inlet data cell, received (SOI) as part of a multicast request, through a self-routing multistage routing network by decomposing (504, 514, 524) the multicast request into one ormore intermediate multicast requests, each intermediate multicast request being a unique subset of the original multicast request which enables a non-blocking, self-routing distribution to a subset of the desired outlets of the original multicast request in one or two passes through the network, and by generating (505, 515, 525) a non-blocking multicast tree based on the intermediate multicast requests and routing the received inlet data cell to the desired outlets. The invention decomposes the original multicast request and generates a non-blocking multicast tree using a cube routing algorithm, a copy routing algorithm, or a combined routing algorithm, which is a combination of the copy and cube routing algorithms.

Title: Needleless injection site with bypass valve arrangement
Inventor: DAOUD ADIB G
IPC: A61M39/00
Filed: 1995-05-18
Abstract: A needleless injection site allowing infusion and withdrawal of fluid therethrough is disclosed. When a compatible blunt male fluid connector fitting is inserted, fluid flow is accommodated; but upon withdrawal of the connector, the injection site is sealed against fluid flow. The injection site includes an elastomeric plunger having first and second ends and having an annular seal portion at a selected distance from the first end, movably contained within a fluid passageway through a housing having first and second ends, and biased towards a first position in sealing contact with the housing at the first end. The housing also has at least one fluid bypass opening into the passageway intermediate the ends a selected distance from the first end. Insertion of a compatible male fitting in the first end of the injection site moves the plunger to a second position where the annular seal portion of the plunger is located adjacent the fluid bypass opening. This allows fluid flow through the passageway, bypassing the seal portion through the fluid bypass.
