Abstract: L'invention concerne un procédé en une seule étape et un appareil pour la production d'une maille métallique expansée à partir d'une bande métallique déformable, notamment une bande de plomb ou d'alliage de plomb que l'on utilise dans la fabrication d'un accumulateur au plomb-acide. L'appareil comprend une paire de rouleaux opposés (116, 118), chacun ayant une pluralité de disques espacés (122, 124) ayant des parois latérales opposées et des surfaces d'outil périphériques, espacées de manière égale et convexes en alternance avec des surfaces sensiblement plates. Le disque présente des entailles radiales ménagées dans les parois latérales opposées des surfaces plates et périphériques en alternance. Les surfaces périphériques des rouleaux opposés sont conçues de manière à interagir sur une bande déformable intermédiaire afin de fendre et de former des segments de câble convexes et des noeuds en alternance dans ladite bande par intermaillage desdites surfaces d'outil formées. Le procédé consiste à fendre et former des rangées transversales de segments de câble allongés et convexes déformés et sortant de la bande plate, dont les segments de câble adjacents par les côtés s'étendent en regard de la bande plate, les rangées latérales séparées par des segments fendus en alternance retenus dans le plan de la bande définissant des noeuds s'étendant latéralement à travers la bande.

Inventor: PUHN FREDERICK A
IPC: H01F41/04
Filed: 1989-12-07
Abstract: ABSTRACT OF THE DISCLOSURE    An electric cable for shielding the conductor therein from tensile  stresses  during  bending  of  the conductor  in  a predetermined lateral direction.   An elongated duct having a pair of opposed sidewalls and a floor therebetween holds the conductive  element,  while  an  elongated  lid  of  relatively substantial thickness is mounted in the opening to the duct between the free ends of the sidewalls.  The lid fills the duct from the opening between the free ends of the sidewalls to the neutral surface produced by lateral bending of the cable in the direction of the floor of the duct.  Bonding material secures the lid and duct in a fixed longitudinal relationship, and a suitable flowable filler encases the conductor in the resulting tubular housing.    The cable disclosed has particular appli-cation to the preservation of the integrity of superconductor materials used as the conductor in the cable.  Preferably, the duct and lid are made of soft and hard copper, respectively.

Title: Incompressible fluid for leaks
Inventor: STENSTROM THEISS
IPC: G01M3/28
Filed: 1990-01-24
Abstract: A B S T R A C T          Disclosure is made of a method and apparatus for monitoring a conduit system for an incompressible fluid for leaks, wherein a testing fluid is introduced into the conduit system during a testing period  when  no  fluid  is  being  withdrawn  from  the conduit system and the conduit system is closed on the supply side by a main valve.    Now,  without increasing the pressure in the conduit system, a check is to be made whether fluid is escaping from the conduit system despite the closed withdrawal valve. For this purpose, without the entry of testing fluid from the supply side of the main valve (1), a predetermined test volume of the testing fluid is introduced into the conduit system (8) under a pressure of the same order as  the fluid pressure on the supply side of the main valve (1) and the time required by the test volume to flow into the conduit system is measured.    A suitable apparatus for this comprises a chamber (12) for introducing the test fluid into the conduit system, the chamber communicating only with the conduit system (8) and having a volume which can be changed between a predetermined first larger value and a predetermined second smaller value.          Further, time measuring means (16) are provided for measuring the time  during  which  the  chamber  changes from  the  first volume to the second volume.            Single figure.

Title: Hinged pipe coupling
Inventor: PALATCHY JOSEF
IPC: F16L17/04
Filed: 1990-02-22
Abstract: A circular pipe coupling for coupling aligned pipe ends is formed of arcuate segments arranged end to end. Each segment has outwardly extending lugs formed on its opposite ends, with the lugs on the adjacent segment ends being interconnected. One of each pair of interconnected lugs is formed with an integral hook, with a corresponding opening for receiving the hook formed on the opposite lug and providing an axle upon which the hook is engaged to form a hinge connection, except that one of the pairs of lugs is connected together by a manually releasable mechanical fastener, such as a bolt. One of the segments may be manually positioned upon the adjacent pipe ends to be coupled, with one or more segments freely dangling downwardly therefrom under the force of gravity, which sections may be manually pivoted upwardly for encircling the pipes and for applying the releasable mechanical fastener.

Title: Determination of dimensions of tubes
Inventor: KUTCHENRITER KEVIN W
IPC: G01B11/08
Filed: 1990-03-07
Abstract: Measurement of lengths for determining the out-side diameter, wall thickness or inside diameter of tubes, specifically tubes of zircaloy alloy for use as cladding for nuclear fuel. The tubes must be maintained to close tolerances. The measurement is carried out with a laser micrometer which generates a planar laser beam. A mandrel of tungsten carbide having a coaxial projection is posi-tioned so that its transverse dimension intersects the beam and is parallel to the plane of the beam. A first length is measured between the end of the beam and the nearest point on the projection. A tube is mounted on the projec-tion with its longitudinal axis parallel to the longitudinal axis of the mandrel and its inner surface engaging this nearest point. A second length is measured from the end of the beam and the nearest point on the tube. The outside diameter is measured as a third length on the shadow of the tube produced by the laser between the shadow of the near-est point and the shadow of the most remote point from the end of the laser beam. The wall thickness is equal to the first length less the second length. The inside diameter 1s the outside diameter less twice the wall thickness. The width of the projection is only slightly greater than the width of the laser beam so that the tube is positioned, as nearly as practicable, on a knife edge. Each measurement of a length is the means of a plurality (typically eight) of measurements taken at eight, angularly and longitudinally, randomly displaced positions of a tube.      Evaluation based on misleading deviations from the control limits, such as a burr or a speck of dust on a tube, are ruled out. An advantage of this invention is that the measurement is carried out with only one instrument.      Prior-art practice requires the use of two instruments: one to measure the OD and the other the ID.

Title: Removal of hydrogen sulfide with on site generated sulfite
Inventor: BEDELL STEPHEN A
IPC: B01D53/77
Filed: 1990-05-31
Abstract: ABSTRACT     Geothermal steam is condensed with a sulfite solution to abate hydrogen sulfide.  A portion of the hydrogen sulfide is converted in the condensation in the presence of soluble cationic polymeric catalysts to soluble sulfur compounds while avoiding elemental sulfur and carbonate formation.  The remainder of the hydrogen sulfide is incinerated and the sulfur dioxide in the incinerator effluent is absorbed in an alkaline solution to form the sulfites for the geothermal steam conden-sation.  By maintaining stoichiometric ratios, the hydrogen sulfide is substantially converted to soluble thiosulfate without the use of  chelates, peroxides or makeup sulfites.
