Title: Method and apparatus for measuring critical current value of superconducting wire
Inventor: SASHIDA TETSUAKI
IPC: G01N27/00
Filed: 1998-02-11
Abstract: Herein disclosed are method and apparatus of measuring a critical current value of a superconducting wire formed by wire sections S(n), n being 1~n~N and initially set to 1. The method is performed by the apparatus and comprises a first step (a) of determining electric currents I(m), m being 1~m~M. The method further comprises a second step (b) of setting m to 1, a third step (c) of passing the electric current I(m) through the wire section S(n), a fourth step (d) of detecting a voltage generated in the wire section S(n) by the electric current I(m), a fifth step (e) of replacing m with m+1, and a sixth step (f) of repeating the steps (c) to (e) until m is equal to M.  The method further comprises a seventh step (g) of replacing n with n+1, an eighth step (h) of repeating the steps (b)-(g) until n is equal to N, thereby obtaining NxM voltages.  The method further comprises a ninth step (i) of setting m to 1, a tenth step (j) of summing up the N voltages generated by the same electric current I(m) to obtain a summation voltage represented by Vsum(m), an eleventh step (k) of replacing m with m+1 after the step (j), a twelfth step (l) of repeating the steps (j) and (k) until m is equal to M, thereby obtaining M summation voltages Vsum(m). The method further comprises a thirteenth step (m) of calculating the critical current value of the superconducting wire on the basis of a reference voltage and a relationship between the summation voltages Vsum(m) and the electric currents I(m), the reference voltage being predetermined depending upon the length of the superconducting wire.

Title: Sanitary aseptic drain system
Inventor: CARNEY MICHAEL
IPC: G05D9/00
Filed: 1996-09-25
Abstract: A buffer system for separating an aseptic fluid handling assembly from a drain includes a fluid receiving housing in fluid flow communication with a fluid discharge outlet of the aseptic fluid handling assembly. A trapped fluid discharge opening near the bottom of the housing, includes a tube which extends above the bottom into a baffle container. The baffle container is in the form of an enclosure having openings at the bottom thereof to admit fluids contained in the housing. A discharge conduit is in fluid flow communication with the discharge opening. A first fluid level detector in the housing activates at least one valve in the discharge conduit by a control which opens and closes the valve in response to selected fluid levels detected by the fluid level detector. In a preferred embodiment the first fluid level detector detects a fluid level exceeding a preselected depth in the housing and a second fluid level detector detects fluid levels dropping below a second preselected level in the housing. Preferably the second fluid level detector is operatively connected to the valve to cause closing thereof in the event the fluid level drops below the second preselected level.

Title: Chest compression apparatus for cardiac arrest
Inventor: HANDSHY ARTHUR W
IPC: A61H31/00
Filed: 1996-11-26
Abstract: The invention is an apparatus for increasing intrathoracic pressure for resuscitating cardiac arrest patients.

Title: Method and apparatus for protecting overhead electric lines from mechanical damage caused by ice storms
Inventor: POWER BERNARD A
IPC: H02G7/16
Filed: 1998-08-14
Abstract: A method of preventing destructive ice rupture impulsive forces on an overhead electric line from reaching and damaging the transmission line towers. The invention comprises forming short barrier segments of greatly reduced ice thickness at points on the conductors and static wires in the line spans on each side of the towers to be so protected. The short barrier segments so formed have a reduced tensile strength of ice proportional to their reduced ice cross-sectional area; they then fracture at a proportionately lower rupture force and thereafter the rupture discontinuity so formed presents a barrier to the transmission of any large destructive rupture forces to the towers from ice rupture on any unprotected portion of the line. The protective short segments of reduced ice thickness are formed by melting the ice thermally or chemically, or alternatively by attaching a short shield or cover over and around the conductor or static wire at the desired points so as to prevent the accretion of supercooled freezing rain, drizzle, fog, cloud or wet snow on the short segments of the conductors or static wires protected by the shields.

Title: Multiplex transmission system and band control method
Inventor: ISHINO FUMIAKI
IPC: H04L47/76
Filed: 1998-07-22
Abstract: A multiplex system for multiplexing packets into ATM cells to be transmitted, which can implement effective use of channels corresponding to irregular traffic qualities in services with various types of quality conditions in an actual environment. In response to a connection establishment request (S402), current required bandwidths B1, ..., Bm are changed to B'1, ..., B'm by adding the new connection, which causes bandwidths X1, ..., Xm which are assigned to the channels to be changed.      When the desired bandwidth including the requested connection is less than an available bandwidth of the corresponding channel, an assigned bandwidth change processing (5406) is .activated to assign new bandwidths in accordance with desired bandwidths.      The bandwidth assignment change is carried out by changing ratios of extraction rates of packets from the buffers in the multiplex system.

Title: Snap acting charge/discharge and open/closed indicators displaying states of electrical switching apparatus
Inventor: WEHRLI HANK ANTHONY III
IPC: H01H3/30
Filed: 1999-05-07
Abstract: Electrical switching apparatus such as a power circuit breaker, network protector or switch has a self-supporting operating mechanism module including a cage formed by a pair of side plates rigidly clamped in spaced relation by spacers. The cage supports all of the operating mechanism components including a helical compression close spring mounted fully between the side plates and coupled to a cam member through a rocker in a manner which maintains the forces longitudinal to the spring. The cam member has a charging cam with a charge profile for compressing the close spring and a close profile through which the spring drives the cam member to effect a controlled release of stored energy to close the contacts of the apparatus. A close prop, spring biased to an unlatched position, is latched to secure the close spring in the charged state by a latch assembly reset by a reset lever separate from the close prop which in turn is reset by rotation of the cam member during charging. An interlock prevents release of the close spring when the contacts are closed or the trip release is actuated. An indicator actuated by a driver pivoted against the cam shaft snaps from a DISCHARGED to a CHARGED indication as the close spring becomes fully charged and the driver drops into a notch created by a flat on the cam shaft. Rotating shafts are journalled solely in confronting apertures in the side plates. The cam shaft is captured between bushings seated in non-circular openings in the side plates thereby eliminating the need for any fasteners.      Likewise, other parts mounted between the side plates and joined by pins having enlarged heads retained by the side plates do not need retainers. Various shafts extending between the side plates have reduced diameter ends of progressive lengths for successive insertion in one side plate to aid in assembly of the operating mechanism.
