Filed: 1975-05-16
Abstract: 1463027 Silver peroxide cells DAINI SEIKOSHA KK 16 May 1975 [8 June 1974] 20845/75 Heading H1B A cell comprises silver peroxide cathodic material 4 and a stainless steel metal mesh 7 coated with a metal which de-oxidizes silver peroxide when the cell discharges, at least a part of the mesh being in contact with the cathodic material. The mesh 7 is coated with one or more of Zn, Cd, Pb, Cu and Ag. The cathodic material consists of a powdered mixture of silver peroxide and graphite which is compressed and pressed into a cathode can 2. Powdered amalgamated zinc forms the anodic material 3 in a can 1 and an aqueous alkaline electrolyte is provided between the cans 1, 2. The coating on the mesh 7 constitutes, with the silver peroxide cathodic material, a local cell in which the silver peroxide on the surface of the cathodic material is de-oxidized to a metallic silver or monovalent silver oxide layer 8. This ensures a constant discharge voltage.

Title: Improvements in damping devices applicable in particular as landing gears for aircraft and more especially light aircraft
IPC: B64C25/62
Filed: 1945-08-14
Abstract: 598,990. Aircraft landing-gear. SOC. ANON. DES USINES CHAUSSON. Aug. 14, 1945. No. 20930. Convention date, May 24, 1944. [Class 4] A damping device applicable to an aircraft undercarriage comprises an elastic member set in tension by an inclined lever made to turn by the ground reaction to the vertical movement of the craft when landing so that the moment arm of the force applied to the elastic member increases with the angle of movement. An inclined arm 6 carrying a shoe 8 with a friction surface 9 sliding along a skid 2 produces torsion, under the ground pressure on the skid during landing, in a rubber annulus 4 connected between the lever pivot ring 5 and the aircraft body 1, The arrangement is such that the moment arm of the applied force increases with the angular movement imposed on the rubber annulus. Modifications in the arrangements of the arms and in the elastic members acted upon are described ; in one example, a spring acted upon by a bellcrank lever is employed.

Title: Improvements in and relating to continuous wave detection systems
IPC: H04L27/06
Filed: 1950-08-24
Abstract: 674,306. Phase measurements. BRITISH THOMSON-HOUSTON CO., Ltd. Aug. 24, 1950 [Sept. 8, 1949], No. 21008/50. Class 37. [Also in Groups XXXV and XL (c)] Signals received as interruptions of a carrier wave are detected by applying the received carrier together with a locally-produced oscillation of the same frequency to two phasedetectors, one of which is used to maintain the local source in determined phase relation with the incoming carrier, the other serving to detect the signal. The received wave after amplification, and with or without frequency reduction, is fed to a resonant circuit 13 which has the centre point of its coil 14 earthed, and its outer ends connected to the two phase-detectors 3, 3<SP>1</SP> in which the interrupted carrier is mixed with the oscillation supplied from the local source 22. The phase-detector 3 comprises a pair of oppositely-poled diodes 7, 10 with earthed load resistors 19, 20. Opposed phases of the carrier wave are applied to the cathode of the diode 7 and the anode of diode 10, while the anode of diode 7 and the cathode of diode 10 are fed in parallel through condensers 5, 8 from the local source 22. The mean of the resulting voltages across the load resistors 19, 20 is derived at the junction 21 of equal resistors 17, 18 and is fed to a frequency controller 24, preferably a valve reactance associated with the source 22. During intervals of no carrier, no voltage is obtained at the junction 21; but when both inputs are applied, the voltage at 21 is a measure of the departure from phase quadrature, both in magnitude and sign. The result is that the source 22 is maintained in phase quadrature with the received carrier. The phase-detector 3<SP>1</SP> is fed in the same manner by the received carrier and the local source, except that a phaseshift of 90 degrees is imposed at 23 on the local oscillation. The carrier and the local source are thus in phase agreement in the phase-detector 31 and the interrupted signal voltage obtained at the point 21<SP>1</SP> may be applied to a relay 26 controlling a signal circuit 27. Alternatively, the detector 3<SP>1</SP> may provide the automatic control voltage, and the detector 3 control the signal relay 26.

Abstract: 419,894. Colour kinematography. FRANCITA, SOC. DE FILMS EN COULEURS NATURELLES, 29, Avenue de l'Opera, Paris. July 28, 1933, Nos. 21312 and 21313. Convention dates, Aug. 1, 1932 and July 3, 1933. [Class 97 (i).] In a method of taking three-colour kinematograph pictures, two images corresponding to the red and green colour records are taken simultaneously from the same viewpoint by means of two objectives, a light-dividing system and a red and a green filter on two diagonally arranged portions of a single image area on a standard film and the third image is taken through a blue filter on a free space in the same image area at a subsequent exposure. Between the exposures the film is fed by half the height of one frame. Apparatus for carrying out the process comprises two objectives 9, 10, Fig. 4; a shutter disc 16 having at one side of the centre two concentric circular apertures provided with a red filter 17 and a green filter 18 and diametrically opposite the filter 18 an aperture covered by a blue filter 19; and a light dividing system in front of the objectives consisting of an apertured mirror 11 and a complete mirror 14.

Title: Improvements in or relating to arrangements for automatically suppressing the damping of the displacements of the gyroscopic axis of a gyro-compass
Inventor: DEROSSI AGOSTINO DANIELE
IPC: G01C19/38
Filed: 1955-07-25
Abstract: 811,031. Gyroscopic compasses. MICROTECNICA S.p.A. July 25, 1955. No. 21391/55. Class 97(3) Damping of the axis of a gyroscopic compass is suppressed by a member which undergoes a movement depending upon the meridian component of the velocity of the compass mounting, the movement being effected through a velocity log indicator in the setting of the gyro compass, in such a way that the damping mechanism is put out of action when the movement exceeds a pre-determine value. As shown in Fig. 4, a platform 8 is rotated by a synchronous mechanism 8‹ so that its direction b-b follows the indication of a ship's gyro-compass, and makes an angle a with an axis o-o representing the heading of the ship. A rod 9, supported on the platform 8, for movement with little friction in the direction of the axis b-b is formed with a glyph with sides 9<SP>1</SP>, 9<SP>11</SP>. A finger 10<SP>1</SP> engages within the glyph and is carried by a rod 10 which is moveable along the axis o-o by a synchronous mechanism 10‹, its displacement being proportional to the speed of the ship as indicated by a log. The movement of the finger 10<SP>1</SP> in the direction b-b therefore represents the component of the ship's velocity in the same direction, and when this quantity exceeds a given value, the finger 10<SP>1</SP> comes into contact with one of the bars 9<SP>1</SP>, 9<SP>11</SP>. This closes an electric circuit which suppresses the damping mechanism, e.g. by closing a valve connecting two liquid dampers. The distance between bars 9<SP>1</SP>, 9<SP>11</SP> may be variable. In an alternative, Fig. 5, a coil 12 is rotatable with respect to coils 13, 14 fixed at right angles. The coil 12 is fed with alternating current of a voltage proportional to the velocity of the ship, and the coil is rotated to keep a constant direction with respect to the indication of the gyrocompass. The voltage of the current set up in coil 14 is proportioned.to the voltage in the coil 12, and to the angle a between the coil 12, 14. This voltage is therefore proportional to the component of the ship's velocity along the meridian, and is amplified by an amplifier 15 and applied to a voltmeter 16. The needle 17 of the voltmeter travels between a pair of contacts 18, so that when -the meridianal component of a ship's velocity exceeds a certain value, an electric circuit between the pointer and the contacts is completed to suppress the damping action. The value of the meridianal component at which damping is suppressed may be varied by altering the relative positions of the contact 18 and the pointer 17.

Abstract: 849,644. Presses for separating liquids from solids. SANDERSON & MURRAY Ltd., and DAVIDSON, M. W. June 24, 1959 [July 5, 1958], No. 21605/58. Class 46. [Also in Group XIII] The present invention is a development of that disclosed in Specification 799,438 (referred to) especially applicable to materials having a high liquid content. Mixture previously introduced through a float-operated non- return valve into a tank 27, Fig. 1, is forced by compressed air through pipe 28 and nozzle 29, Fig. 1A, to the region between two endless filter bands 14, 19, Fig. 2, which are temporarily stationary. The lower filter band is underlain by a screen 12 and the upper filter band is overlaid by a sealing ring 17, Figs. 1A, 2 and 5, into which the upper filter band (being slackly mounted) is caused to bulge upwards by the incoming mixture. Eventually a lower float (not shown) in tank 27 causes the mixture-inlet valve to open and the compressed air-valve to close. Next, the sealing ring 17 is driven further downwards by piston and cylinder assemblies 22, 23, Figs. 1A, 1B, 2, 2A, so that a sponge rubber ring 26, Fig. 5, on its underside, is compressed. A bellows 10, Figs. 1A, 1B, suspended by springs 10<SP>1</SP> is then inflated by pressure medium and presses down upon the envelope formed by the upper filter band 19. Liquid passing through screen 12 flows to a drain (not shown) and liquid passing through the upper filter band may pass to drain along grooves in a flexible sheet (not shown) provided between the band 19 and the bellows 10.. The bellows 10 is then deflated and the sealing ring 17 raised to permit the filter bands to be advanced to the right. The bands are subsequently cleaned by brushes 33, 35. Where the material to be treated is not liable to adhere to other materials the upper band 19 may be dispensed with and a bag may be provided, secured by its edge to the sealing ring 17. The cycle of operations may be controlled automatically.
