Title: Electrodes for use in batteries
IPC: H01M4/04
Filed: 1975-03-12
Abstract: 1476550 Making battery electrodes ENERGY RESEARCH CORP 12 March 1975 [18 March 1974] 10329/75 Heading H1B A method of making a hydrophilic electrode comprises blending powdered active material with dry powdered P.T.F.E. in an excess of a non-aqueous liquid lubricant to form a homogeneous mixture, removing some of the lubricant from the mixture by filtering, reducing the thickness of the mixture to form a sheet of fibrillated P.T.F.E. containing the active material and lubricant, and removing the remainder of the lubricant from the sheet. The lubricant may be mineral spirit, propylene glycol or a petroleum solvent and the slurry it forms with the active material and P.T.F.E. is filtered in a Buchner or centrifugal filter to remove a certain amount of the lubricant. The filtered mixture is then kneaded in a blender at temperatures between room temperature and 200‹ F. The mixture is milled between rollers, folded and then passed again through the rollers, this process being repeated several times. The slab formed is reduced in thickness to form a sheet which is dried in air, the temperature being maintained below the sintering temperature of P.T.F.E. The sheet is cut into pieces of a suitable size and two pieces are compressed on to each side of a metal grid. The grid may comprise silver plated copper, silver, nickel or tantalum and the active material may be zinc oxide, silver oxide, cadmium oxide, mercuric oxide, copper chloride, nickel hydroxide or lead oxide. Graphite may be added to the active material and the electrodes may be used in nickel-zinc, silver oxide-zinc, nickel-cadmium, mercury-cadmium, nickel-hydrogen or leadacid batteries.

Patent GB-906675-A (GB)
Title: Voltage control systems
IPC: H02P7/28
Filed: 1960-03-24
Abstract: 906,675. Electric motor control systems. BROOKHIRST IGRANIC Ltd. March 24, 1960 [April 6, 1959], No. 10463/60. Class 38 (3). In a voltage supply network for controlling a direct current motor, the motor armature voltage is controlled by the voltage at terminals 8, 10 and the weakening of the field excitation is controlled by the voltage at terminals 12, 14. The voltage at terminals 8, 10 is developed across a resistor R2 connected in series with the emitter-collector circuit of a transistor T1 to a constant voltage supply 2, 6. The emitter-base bias of transistor T1 is derived from a variable reference voltage at terminals 2, 4 through a resistor R1 and Zener diode ZD1 so that as the reference voltage increases the voltage at terminals 8, 10 rises linearly, Fig. 2, until the Zener diode conducts; the voltage at terminals 8, 10 then being maintained constant. The field weakening voltage at terminals 12, 14 is derived across a resistor R4 connected in series with the emitter-collector circuit of a transistor T2 to the constant voltage supply 2, 6. The emitter-base bias of the transistor T2 is derived from the variable reference voltage at terminals 2, 4 through a Zener diode ZD2 so that the voltage at terminals 12, 14 is zero and the field current maintained at a maximum, Fig. 2, up to a value of reference voltage at which the Zener diode ZD2 conducts. Above this value of reference voltage the emitter-base bias of the transistor T2 is determined by Zener diodes ZD3, ZD4 and resistors R5, R6 connected as shown. The Zener diodes conduct at different values of reference voltage so that the effect of the field weakening voltage at terminals 12, 14 on the motor field current is to give an approximation to that field current/reference voltage curve, Fig. 2, which causes the motor speed to vary proportionally to the reference voltage. The slopes m<SP>1</SP>, n<SP>1</SP> of the approximate curve are determined by the resistors R5, R6. A rheostat MF adjusts the maximum field weakening voltage. The network is arranged as a module adapted for putting in plastic, the terminals and the operating arrangement for the rheostat being provided externally. Specifications 906,672 and 906,674 are referred to.

Abstract: 1303356 Measuring resistivity: measuring moment of inertia electrically A Z CHABERSKI 6 March 1970 [24 June 1969] 10799/70 Headings G1N G1U To determine the resistivity of a sample of semi-conductor material, measurements are made of (i) the torque on the sample when rotatably supported in a rotating magnetic field in a particular orientation, and (ii) the moment of inertia of the sample about its axis of rotation. It is said that the resistivity can then be calculated provided the orientation was correctly chosen. The method is said to be applicable to samples of any shape, e.g. toroidal (66), Fig. 4.  Apparatus for making these two measurements comprises a rotatable rod 10, Fig. 1, supported solely by oppositely-wound springs 12,14 and carrying a hollow plastics sphere 58 whose orientation is adjustable and which serves as a container for the sample. To make the first measurement, four coils 70,72 surrounding the sphere 58 provide the rotating magnetic field and a pointer 20 indicates the resultant deflection of the rod, from which the torque may be calculated. To determine the moment of inertia of the sample, the rod is caused to oscillate by supplying A.C. to coils 30, 32 surrounding a copper ring 26 on the rod, and the frequency of the A.C. is varied until the rod resonates, as observed by the deflection of pointer 20, measurements of the resonant frequency being made both with and without the sample present in sphere 58. A permanent magnet 34 surrounding a further ring 28 on the rod provides damping.

Title: Improvements in or in connection with Glass Shaping and Blowing Machines.
Inventor: ROIRANT EMILE
IPC: C03B9/193
Filed: 1916-08-01
Abstract: 108,351. Roirant, E. Aug. 1, 1916. Blowing.-In a machine for manufacturing "pressed blown " articles only one set of moulds is employed, but these are so arranged that the formation of a parison takes place simultaneously with the setting of the previous parison. The mouth or opening of the finished jar is automatically calipered or reformed while the jar is in the finishing mould. Two plungers 10 are mounted at diametrically opposite points of a carrier 4 which is rotatable on a shaft 3 and may be moved vertically by means of a lever 7. A second carrier 11 also rotatable on the shaft 3 but not movable vertically carries a collar 17 which acts as a guide or centring device for the plunger. Two levers 14 pivoted on opposite sides of the carrier 11 serve to open the neck mould 19, the halves of which slide in grooves on the underside of the carrier. A third carrier 20 which is not rotatable but can be moved vertically on the shaft 3 through toggle levers 27, 29 by means of a treadle 31 supports the parison mould 21 and is connected by links 38, 36 to the finishing mould 32 so that downward movement of the carrier opens the finishing mould. The blowing head 42 carried by a lever 43 is depressed on to the finishing mould by means of a treadle 46 and a valve 48 which controls the blowing air is opened by the short arm of the lever 43 as the head 42 is seated on the mould. In use, after the parison has been formed by the plunger, the parison mould is lowered so as to leave the parison suspended from the neck-mould, the parison being stretched if desired, as described in Specification 108,352. The carrier is then rotated to convey the parison into the open finishing mould 32, and after the mould is closed the neck mould is opened by means of the levers 14 to let the parison fall into the finishing mould. The parison is now blown by lowering the blowing head 42. When the blowing is finished, the head 4 is lowered to form a new parison, and at the same time the second plunger enters the mouth of the finished article which is setting in the finishing mould and removes any distortion which may have occurred during blowing.

Title: Improvements in or relating to means for extracting oil from oil-bearing seeds or nuts
Inventor: ZIES CARL WILLIAM
IPC: C11B1/10
Filed: 1961-03-27
Abstract: <PICT:0918438/III/1> <PICT:0918438/III/2> As shown, an apparatus in which oil is extracted from oil-bearing seed or nut material comprises an aperture 13 (see Fig. 1A) into which the oil-bearing material is fed, and a helical worm conveyer 11 which transports the oilbearing material to vertical shoot 14 which is likewise provided with a worm conveyer 16, which forces the material down through a pair of successive vertical barrel sections 22 and 23 (see Fig. 1). These barrel sections, constructional details of which are given, are so disposed as to prevent solid material from escaping radially outward, but permit liquid to be squeezed through the minute interstices when the pressure is applied.  At the lower end of the vertical barrel is an imperforate collar 33 within which the oil-bearing material is compacted into a plug by the gradually increasing pressure; this plug eventually passes into horizontal barrel 34 where it is advanced by means of helical screw flights 36 while gradually increased pressure is exerted.  This increase of pressure may be achieved by decreasing the pitch of flights 36, by increasing the shaft root diameter towards the exit end, or by restricting the escape opening within an automatic choke assembly 37. The extracted material eventually leaves the apparatus through aperture 41.  The horizontal barrels 34 is also equipped with barrel bars similar to those contained in the vertical section. During its passage along horizontal barrel 34, the material may be treated with an oil solvent, e.g. methylene chloride, trichloroethylene, or heptane, supplied by pipes 71 and 72 and injected into barrel 34 by means of nozzles.  The conditions under which this solvent extraction is performed are so chosen that the solvent will flash off the miscella at the barrel bar interstices with sufficient force to atomize the entrained dissolved oil into a mist of oil particles; these oil particles collect within housing 67 or on the inner wall of the housing and are removed by means of lines 76 and 78.  The oil extracted by means of pressure only in the vertical section of the apparatus collect in trough 49 whence it may also be removed (means not shown).  In a further embodiment (not shown), the solvent extracted cake in horizontal barrel 34 may be treated with injected water or steam near the discharge end of the barrel; this injection of water cools the cake, produces steam in the barrel, and so desolventizes the cake in a single operation.
