Title: Device for use in veterinary and medical instruments
Inventor: BRUNELL ROBERT A
IPC: A61B1/00
Filed: 1984-06-28
Abstract: A device for veterinary and medical instruments such as endoscopes and bronchoscopes comprises a connection 24 to a pump continuously drawing a vacuum or taking a suction on the system with means for bypassing the suction in full or in part. In operation, suction through connection 24 draws on atmosphere through bore 23. When the latter as stopped by a finger 8, flow from atmosphere passes through bore 19, tube 17, to suction source 24 and also from the scope via passage 16. When both passages 23, 19, are stopped, full suction is drawn through bore 16. If a syringe 5, Fig. 4 (not shown), is fitted, valve 18 seals passage 16. <IMAGE>

Patent GB-2147425-A (GB)
Title: Leakage detection
Inventor: ARMELL RICHARD ALVIN
IPC: G01M3/04
Filed: 1984-09-26
Abstract: Pipe coupling leakage detecting apparatus comprises an elongate tool (76) supporting a coupling (12, chain dotted lines) to be tested. An end assembly (14) carries several elongate members (34) extending parallel to the tool which have an annular collector (36) at their free ends which collects any leakage search gas from the coupling being tested and also restrains the coupling against axial movement. The elongate tool supports an axially compressible seal member (84) and fluid pressure means (90, 92, 106) radially expand the seal into engagement with the pipe by such compression. Means are provided for introducing a search gas into a space (11) defined by the tool and the coupling so that the coupling thread is exposed to the search gas and the collector (36) serves to collect any leakage search gas. A detector such as a mass spectrometer is provided for quantitatively measuring any search gas which has been collected by the collector (36). <IMAGE>

Title: Electrochemical cell manufacture
Inventor: HOOPER DR ALAN
IPC: H01M10/052
Filed: 1984-10-18
Abstract: A solid state electrochemical cell is made by assembling together in electrical contact an anode having lithium as its active material, a polymeric electrolyte (e.g. based on poly(ethylene oxide) and LiF3CSO3), and a cathode in the form of a composite of an insertion electrode material (e.g. V6O13) or similarly active material in combination with a polymeric material. Either before or during assembly the anode, electrolyte and cathode are heated together under pressure. This removes the necessity for applying an external pressure to the cell during cycling.

Title: Apparatus and method for de-watering slurry
Inventor: BIRKETT MELVIN HERBERT
IPC: B01D35/027
Filed: 1986-03-20
Abstract: Slurry is fed into a chamber 221 which is generally impervious except for a wall 220 which separates it from a chamber 222. Wall 220 is made of slightly spaced metal, wood or concrete planks between which the liquid content of the slurry is filtered. Chamber 222 has an outlet comprising a weir 223 which is progressively lowered, after an initial settling period, to allow discharge of filtrate. Solids build up between the planks to act as filter aid. Solids settling in chamber 222 are returned to chamber 221, and eventually chamber 221 contains mainly settled solids. Figure 11 shows a movable apparatus, but larger scale apparatus is prefabricated or permanent and may be large enough to allow a mechanical digger into the main chamber to remove the solids. Settling maybe improved by adding flocculants or mixing thick and thin slurries. <IMAGE>
