Patent GB-2028870-A (GB)
Title: Electrolysis Method and Apparatus for Treating Solutions
IPC: C25C7/00
Filed: 1978-07-26
Abstract: In the past, problems have arisen when electrolytically treating very dilute solutions, such as aqueous metal salts to remove metal, due to depletion of ions in the boundary layers adjacent to the electrodes. This invention provides (in a preferred embodiment) a pair of relatively rotating disc electrodes closely spaced to define a very thin gap between the faces and with electrolyte solution being pumped into the centre of the gap through one of the discs so that there is always a rapidly moving thin film of solution being electrolysed in the gap and no static boundary layers can form adjacent to the electrode surfaces. The invention is particularly useful in the recovery of metal from dilute solutions in waste water treatment. <IMAGE>

Patent GB-2014331-A (GB)
Title: Flash Welders
IPC: B23K11/24
Filed: 1978-10-09
Abstract: An electrical control terminates the upset current of a flash welding process as a function of platen position. It comprises an operational amplifier which is used as a comparator. Voltage from a first source is fed to the comparator, this voltage being adjustable to provide for termination of the upset current at a selected position of the movable platen of the flash welder. Voltage from a second source is impressed upon a potentiometer and this voltage is varied in magnitude as the movable platen moves toward its closed position on the stationary platen. The variable voltage from the potentiometer is also fed into the comparator. When the algebraic sum of the voltage from the potentiometer and offset voltage of the comparator becomes of a magnitude (more or less) than the adjusted voltage from the first source, the comparator acts in the manner of a precision switch to set into operation means to terminate the upset current. <IMAGE>

Abstract: A clamping device (1) comprises an elongate base (4) on which is rigidly mounted a first arm (5). A second arm (16) is slidable on the base and carries a screw (19) which engages the rear face of the base (4) to define a pivot axis. A second screw (22) is manually rotatable to engage the base (4) and pivot the arm (16) about the pivot axis until edge (17) of the face plate (15) engages the base to lock the arm (16) in position. By suitable pre-setting of screw (19) the arm (16) locks when the face plates (8 and 15) are parallel. The clamping device may be used to support a microfilm projector. <IMAGE>
Patent GB-2011102-A (GB)
Title: Photographic processing method
IPC: G03C5/30
Filed: 1978-10-26
Abstract: This invention relates to the use of metal ions in low valency states as silver halide developing agents for exposed black and white photographic material. Solutions of metal ions in a higher valency state than is required for their use as silver halide developing agents are reduced to the required low valency state by contacting them with a metal higher in the electrochemical series than the metal ion, the reduction taking place in the photographic material itself so that oxidation of the low valency ion by air is minimised. The reducing metal may be Zn, Sn, Fe or In and may be present in the photographic assembly as, for example, a layer vacuum deposited on the film base or a layer containing a colloidal dispersion of the reducing metal. The preferred reducing metal ions are Cr<++>, V<++> and Ti<+++>.

IPC: F15B15/08
Filed: 1981-04-09
Abstract: A fluid pressure operated actuating device for opening and closing a door comprises a double- acting piston 5 and cylinder 4 arrangement. The door is moved by a driven rotary spindle 16 and a screw transmission in the form of rollers 8, 9 operating in inclined slots 15, 10 in inner and outer tubes 12, 11 respectively converts linear movement of the piston into rotary movement of the spindle. The screw transmission is self-locking and in end position. Pusher means move the screw transmission out of the end position on failure of the piston and cylinder arrangement. In the end closure region, a piston rod 6 pushes against a spring plate 19 and as soon as the pressure of the working fluid under the piston 5 is relieved a compression spring 18 moves the piston rod 6 with a yoke 7 downwardly. <IMAGE>

Title: A method of manufacturing an electret assembly
IPC: B29C65/00
Filed: 1981-05-20
Abstract: A method for producing stable, layered electrets includes the steps of placing a sheet of glassy polymer or copolymer of high molecular weight, such as polyethylene terephthalate, between two, somewhat larger in planform, sheets of polyvinyl chloride and/or polyvinyl acetate formulation, to form a sandwich structure which is then compressed and heated to approximately 300 DEG  F. At this temperature the exterior polyvinyl chloride or copolymer sheets are polarized and displaced under pressure over the interior sheet to charge the interfaces of the exterior and interior sheets. The heat, furthermore, bonds the peripheral edges of the larger exterior sheets to each other thus forming a hermetically closed container within which the charged interfaces will reside.
