Title: Improvements in or relating to electrical dust-precipitating units
IPC: B03C3/82
Filed: 1946-04-25
Abstract: 611,428. Electrostatic precipitation. AMERICAN AIR FILTER CO., Inc. April 25, 1946, No. 12473. Convention date, May 1, 1945. [Class 39 (i)] An electrostatic dust-precipitating apparatus is constructed of plate assemblies such as are shown in Fig. 4, so built up that electrically opposite assemblies 3 and 4 normally fit into interleaved relationship (Fig. 6, not shown), and are so arranged that each assembly is removably supported in the housing independently of the other. The plates 3 of the grounded assemblies have a central clearance space 10 and are rigidly held in spaced parallel relationship by spacers on securing rods 7, which terminate in nuts at either end. The grounded plate assemblies are mounted in a housing 11, Figs. 11, 13, with their plates extending vertically in the direction of gasflow, the lowest one resting on the bottom of the housing, and the upper ones on,trackways 16 provided by shelves 15. Secured to each side of these assemblies is a shallow trayshaped member 17 to close the space between the end of each assembly and the housing wall. After being slidably inserted along these tracks, the grounded assemblies are positioned by vertical flanges 18 and latching flanges 20. At each side of the rear of the housing, a pair of insulators 30 support a metal bus-bar 31 which is provided with several pairs of oppositely projecting transverse pins 32. Each of the insulated assemblies carries a pair of forks 33, Fig. 15 (not shown), each of which straddles the bus-bar and rests on the upper sides of a double pin, so that the rear ends of the said assemblies are supported and electrically connected, while insulated as a whole from the housing. The front end of each insulated assembly is supported by a rod which passes laterally through a pair of lugs attached to the assembly. The rod is insulated from the lugs, Fig. 17 (not shown), and rests at each end in latching grooves 37 at the front ends of the trackways 15. Thus the insulated assemblies may be removed bodily first, and then the grounded assemblies, this order being reversed on replacement. The walls of the housing extend upwardly beyond the top wall, as at 12 and 13, thus forming a space 14 for containing the necessary wiring.

Patent GB-1467212-A (GB)
Title: Camera including a device for avoiding incorrect exposures
IPC: G03B9/64
Filed: 1975-03-26
Abstract: 1467212 Cameras PENTACON DRESDEN KAMERA-UND KINOWERKE VEB 26 March 1975 [28 March 1974] 12605/75 Heading G2A A camera has means for indicating when there is insufficient or too much light for a correct exposure and means for preventing shutter release in such conditions. As shown, if the light level is correct, depression of a shutter release 1 pivots a lever 3 anti-clockwise. A pawl 9 pivoted on lever 3 is engaged by a lug 10 of a lever 4 so that, as lever 3 pivots, lever 4 follows and rotates a diaphragm setting ring 21 clockwise to open the diaphragm. When the correct aperture is reached, an armature 22 of an electromagnet 23 stops ring 21. Lever 4 and its lug 10 are thus halted allowing pawl 9 to pivot anti-clockwise as lever 3 continues its movement. Pawl 9 enters a recess 14 in a lever 5 and thus does not engage lever 5. Release 1 continues its movement and operates the shutter. If there is too much light, armature 22 is released immediately so pawl 9 is freed early and engages a surface 13 of lever 5 to move lever 5. Lever 5 has a lug 15 which (a) closes switch contacts 16, 17 to energize a warning light 18 and (b) abuts a stop 19 to prevent further depression of the release 1. If there is insufficient light, armature 22 is not released and pawl 9 is carried by lever 3 into engagement with the pawl of level 5 below the recess 14. Lever 5 then operates the light 18 and blocks release 1 as before. In alternatives, (not shown), ring 21 sets the shutter speed and the contacts 16, 17 are carried by the lug 15 and stop 19.

Filed: 1975-03-26
Abstract: 1489277 Making electrodes for storage cells COMPAGNIE GENERALE D'ELECTRICITE 26 March 1975 [28 March 1974 (2)] 12724/75 Heading H1B A method of making an electrode comprises covering at least part of an electrically conductive core 1 with material 2 which is non- adhesive with respect to an electro-chemically active coating 5 and subsequently applying the coating so that a space 6 is formed between the material and the coating to allow the escape of gas during use of the electrode. The core consists of a sheet of silver plated nickel on each face of which a layer of P.T.F.E. is sprayed. The layers are then sintered and scraped to leave strips 2. Alternatively the strips may be formed using a P.T.F.E. emulsion or by masking portions 3 of the core and spraying it with P.T.F.E. Instead of P.T.F.E., polydichlorodifluoroethylene may be used. Holes 4 are provided in the core to secure the active coating 5 which is formed in a manner similar to that described in Specification 1,406,007. Due to the non- adhesion of the coating 5 with the strips 2 the spaces 6 are formed and allow the escape of hydrogen produced during use of the electrode. In a modification, Fig. 5 (not shown) the core consists of a grating which is packed with a ZnO-P.T.F.E. paste, the gas spaces being formed due to the non-adhesion of the paste with the active coating.

The required micro-structure is achieved by homogenization at 550-630% for 15 minutes to 24 hours followed by quenching.  The alloy may be used for the anode of a primary cell or a cathodic protection system.
Patent GB-709437-A (GB)
Title: Improvements in or relating to the production of amino acids
IPC: A23J3/34
Filed: 1951-05-30
Abstract: Amino acids are made by degrading a protein with enzymes obtained by mould cultivation.  During the degradation a "sliding" pH is maintained.  The protein may be broken down to more than 95 per cent in a few days.  The mixed enzymes may be isolated from mould cultures by solvent extraction, advisably after the cells have been burst, e.g. by treating with concentrated salt solutions or repeatedly freezing and thawing. Cultures specified are Aspergillus alleaceus, parasiticus, oryzae, wentii and fumigatus and Penicillium glaucum, roseocitricum and notatum.  Ferments obtained as in Specification 700,876 may be used.  In an example a moist mycelium obtained on growing Aspergillus oryzae on a nutrient medium containing wheat bran and fish meal is kneaded with water, repeatedly frozen and thawed, extracted with water and reacted at 45 DEG  C. with casein (previously swollen by treatment with water) in toluene until sufficient degradation is achieved.

Title: Improvements relating to accelerometers
Inventor: DIPROSE KENNETH VICTOR
IPC: G01P15/10
Filed: 1955-05-03
Abstract: 789,611. Accelerometers. ROE & CO., Ltd., A. V. April 24, 1956 [May 3, 1955], No. 12763/55. Class 40 (1). In an accelerometer, the tension of a vibrating wire is varied by acceleration, changes in its vibration frequency being detected by reference to a second wire which, in the absence of acceleration, vibrates at the same frequency as the first wire. As shown, two wires 1, 2 disposed between magnet poles along an axis A-A of the instrument housing are kept in oscillation at their natural frequencies by oscillators 10, 11. Acceleration displaces two weights 8, 9, each connected to one of the wires 1, 2, and inter. connected by a spring 7, thus increasing the frequency of oscillation of one wire and decreasing that of the other. The output of the oscillator 10 is fed to a phase-splitter 12 which produces two signals in quadrature, each of which is mixed with the output of the oscillator 11 in one of two modulators 13, 14, whose output signals are used to drive a two-phase synchronous motor 15 which in turn drives a counter 17 to indicate in terms of velocity.

Abstract: 696,278. Dishwashing machines. BRITISH THOMSON-HOUSTON CO., Ltd. May 21, 1952 [May 21, 1951], No. 12866/52. Class 138 (i). In a dishwasher having a dish-holding tub with side walls and a sprayer for cleansing liquid which wets the walls during the washing operation, means are provided for drying the dishes in the tub and comprise a source of air under pressure outside the tub, an air passageway leading from the source to a side wall and opening into the tub and a screen on the wall covering the opening, which screen blocks the passage of air into the tub while wet, but permits the passage of air when allowed to drain dry. As shown in Fig. 1 the tub 1 is closable by a cover 3 and has air vents 4 in its side walls 2. An impeller 5, for spraying water over the dishes supported in racks (not shown), is driven by a motor 7. This motor also drives an air blower 10 having an inlet 11 and an outlet 12 connected by a duct 13 to an opening 14 in a wall 2. The opening 14 is covered by a fine wire screen 16, Fig. 2, supported in a frame 17 and removably mounted in the opening as by spring legs 18. The tub is provided with an electric heater 9 and a drain valve 8. In operation water, supplied to the tub to the level W, is heated, and sprayed by the impeller over the dishes. During this time the screen is maintained in a wet condition and the pressure of the air is insufficient to allow it to pass therethrough. However .when the tub is drained the screen will also drain and allow passage therethrough of the air which is then heated by the heater 9, circulated by the impeller and finally exhausted from the tub through the vents 4. A spray head may be provided in lieu of the impeller, and located at any convenient position in the tub. The motor 7 would then drive the pump for supplying liquid to the spray head. The pipe 13 is provided with a bend 15 to prevent water entering the blower during the washing operation. Specifications 557,034 and 665,691 are referred to.
