Title: Pinces verrouillables
Inventor: KERR HELEN
IPC: A47G21/10
Filed: 2003-10-16
Abstract: La présente invention concerne des pinces (10) destinées à saisir des articles, qui peuvent être verrouillées de manière réversible dans une position fermée par un mécanisme de verrouillage rotatif (22). Selon cette invention, ces pinces comprennent une paire d'éléments allongés (14, 16) joints au niveau d'un point d'articulation (17) permettant un mouvement pivotant entre une position ouvert et une position fermé destinées à saisir des articles. Un mécanisme de verrouillage est prévu de manière à tourner autour d'un axe longitudinal s'étendant entre les éléments allongés et agencé de façon à tourner entre une position déverrouillé et une position verrouillé, verrouillant de manière réversible les éléments allongés dans la position fermé. Ce mécanisme de verrouillage comprend, de préférence, une partie arrêt (42) définissant, en coupe, une première dimension plus large (44) et une seconde dimension plus étroite (46) de sorte que, lorsque le mécanisme de verrouillage est tourné en position verrouillé, la dimension la plus large arrête le mouvement pivotant des éléments allongés.

Abstract: In  a  marine  seismic  data  acquisition  system,  a plurality of seismic data transmission paths are utilized to conduct seismic data to a central recording unit from seismic  data  acquisition modules  positioned  along  the length  of  cable.    Signals  from  a  plurality  of  data acquisition modules are applied to each of the transmission paths.    Data  acquisition modules  which  apply  seismic signals to a given transmission path may be spaced and substantially uniform distances along the length of the cable and may be interspersed with data acquisition modules which apply seismic data to each of the other transmission paths.  The operation of the data acquisition modules is synchronized by means of a signal transmitted continually from a central recording unit.  Each section of the cable includes a plurality of remote units distributed along the cable section for detecting seismic signal.  Each section includes a data acquisition module which receives command signals from a central recording unit and which receives seismic data signals from the remote units and transmits seismic data signals to the central recording unit.

Abstract: A system for integrating and modularizing wiring within a building is provided herein. A unitized destination terminal integrates a diverse assortment of communication connectivity needs with power distribution. The terminal mounts near a work surface in each one of a multiplicity of work areas within a building. An integrated communication cable bundle transports a variety of different communication circuits away from the work areas towards a common communication distribution area. The integrated communication cable bundle is routed through an integrated raceway, which manages the placement and housing of communication systems as a unit that additionally includes power distribution systems. Cabinets, at the common communication distribution area and at a central connectivity area for the building, terminate communication cabling at a variety of socket connectors. The central connectivity area couples e.g., to PBX, mainframe computer controllers, or other connectivity devices. A variety of jumper cables mate with the socket connectors in a selectable and easily-alterable pattern to couple the connectivity devices, e.g., a PBX, to the unitized destination terminals in the work areas. Extensive modularization and off site connectorization permit such system to be installed quickly and inexpensively without the use of highly-skilled electricians. The extensive connectorization, as opposed to hard-wiring, and integrated management of a wide assortment of communication channels promotes flexibility.

Title: Method and apparatus for adjusting the distance between the poles of electrolysis cells
Inventor: SPARWALD VOLKER
IPC: C25B9/01
Filed: 1990-03-08
Abstract: ABSTRACT      A method and apparatus for adjusting the distance between the anodes and cathodes in an electrolysis cell includes first and second anode beams, movably disposed in an upper and lower relationship.  The anode beams are intercon-nected by a spindle having upper and lower portions which are oppositely threaded such that rotating the spindle in a first direction moves the beams towards each other and rotating the spindle in the other direction moves the beams away from each other.  Cell anodes are selectively attached to one of the anode beams, dependant on the desired direction of adjustment. By attaching the anodes to one or the other anode beam, as they are cycled towards and away from each other, individual anode adjustment in either direction can be achieved.  If desired, an essentially constant downward motion may also be provided, without requiring a halt in cell operation.  Consequently, cell efficiency is increased and the cell remains on-line for longer periods, increasing production capacity.

Title: Hydraulic sensor for quench detection and location in superconductors
Inventor: WOLFE WILLIAM R
IPC: G01N7/00
Filed: 1990-08-30
Abstract: W.E. No. 55,096 ABSTRACT OF THE DISCLOSURE           The   present  invention  provides  a hydraulic sensor  for   quench   detection   and   location   in   a superconductor,  and particularly a superconductor used to form an inductor or a magnet.  The sensor consists  of  an insulating  tube  (1)  adjacent to and preferably co-wound with the super conductor (2) and filled with a supercooled working  fluid  (3).   When  joule  heating  occurs in the superconducting conductor as a result of a portion  of  it becoming  normal,  the heat is transferred directly to the corresponding portion of the adjacent tube (1).  This heat causes the vapor pressure of the working fluid (3) at that point in the tube to  change.   This  change  in  pressure propagates in both directions at the speed of sound in the working fluid.  By detecting with  sensors  (6,7)  when  a change  in  pressure arrives at the ends (5,6) of the tube (1) and calculating the  difference  between  the  arrival times,  not  only  can a quench be detected, but the exact location  of  the  quench   initiation   region   can   be determined.
