Title: Phase modulation apparatus
IPC: G01S13/26
Filed: 1972-05-30
Abstract: 1432541 Phase-modulation; radar DEFENCE SECRETARY OF STATE FOR 8 May 1973 30 May 1972] 25344/72 Headings H3R and H4D In phase-modulation apparatus for an interrupted carrier wave coherent radar, the phase-modulation is effected by controlling reflection at the end of a delay line 7 and the phase of the reflected wave determines the phase of a carrier wave generator during a next transmit period and the carrier wave generator is switched off during receive periods. In the embodiment, which is a proximity-fuze radar mounted in an anti-aircraft projectile, a pseudo-random generator 9 controls a p.i.n. diode 8 to cause 180 degree phase-change reflection (when in one state) at the end of a surface acoustic delay line 7, and generator 9 is connected also to a shift register 10 and thence to balanced mixer 11 for determining target range as described in Specification 1,404,590. Phase coherence between successive operations of oscillator 1 is maintained. The fuze is set off by a threshold circuit 17. The p.i.n. diode may be replaced by a varactor. It is stated that linear phase-modulation can occur and that the emitted signal is free of undesired amplitude modulation: the apparatus may then be utilized as a synthetic Doppler simulator.

Patent GB-357740-A (GB)
Title: Improvements in the manufacture of rubber articles by electrodeposition
IPC: C09D5/44
Filed: 1930-08-28
Abstract: In the electrophoretic deposition of rubber or other organic materials on objects of any desired contour for coating or for subsequent removal, dispersions are employed whose alkalinity and resistivity are so adjusted that the resistance of the deposit increases more rapidly than its thickness; the thickness rapidly approaches a limiting value which is the same for prominent and recessed parts of the object.  Natural latices of rubber, guttapercha or balata or artificial dispersions of these or of reclaimed rubber, synthetic rubber or rubber isomers together with addition agents may be employed and may be previously purified, concentrated or vulcanized.  The preferred conditions for rubber are an alkalinity corresponding to a pH value 9-12 and resistivity p  50-1000 ohms per cm. cube.  A high alkalinity is necessary when the resistivity is low and conversely.  The initial current density may be 0,02-0,5 amps. per sq. inch.  With a high initial current density, a smaller final thickness is attained. The concentration may be 5-70 per cent.  In an example ammonia-preserved latex containing 30 per cent rubber is aerated to remove a portion of the ammonia until it has an alkalinity corresponding to pH = 9,7 and a resistivity of 192 ohms per cm. cube, and is electrolyzed with a zinc anode and a cathode separated by a porcelain diaphragm using an initial anodic current density of 1/10 amp. per sq. inch.  Deposition practically ceases after 2 1/2 minutes, a uniform layer of 0,032 inch thickness being obtained.  In another example a centrifuged latex containing 62 per cent rubber is aerated to reduce its alkalinity to pH = 9,8, the resistivity being 200 ohms per cm. cube.  An initial current density 0,1 amp. per sq. inch produces deposit 0,01 inch thick, the current falling to zero in 45 seconds.  The same latex diluted to 9 per cent concentration giving pH = 9,1 and resistivity 625 ohms per cm. cube when electrolyzed with initial current density 1/20 amp. per sq. inch gave a deposit 0,115 inch thick, current ceasing after 9 1/2 minutes.  In another example latex concentrated by evaporation in the presence of protective colloids is diluted to concentration 20 per cent, giving pH = 11,2 and resistivity 143 ohms per cm. cube.  With initial current density 1/20 amp. per sq. inch current ceases after 11 minutes giving a deposit of 0,055 inch.  With initial current density 1/10 amp. per sq. inch, current ceases after 2 1/2 minutes giving a deposit of 0,022 inch.  A latex composition containing 100 parts rubber, 3 parts zinc stearate, 3 parts sulphur, 5 parts cotton-seed oil, 3/4 part accelerator is diluted to 25 per cent total concentration, and 0,05 per cent ammonium chloride added to bring pH to 10,3 and resistivity to 322 ohms per cm. cube.  A deposit is produced on a glove form with initial average current density 1/10 amp. per sq. inch.  Current ceases after 7 minutes giving a deposit of 0,05 inch.  The dry deposit is vulcanized by heating in steam under 40 lbs. pressure for 30 minutes.

Title: Improvements in and relating to the welding of thermoplastic materials
Inventor: LIDSTER STANLEY
IPC: B29C65/48
Filed: 1961-07-19
Abstract: A polyurethane foam is rendered readily weldable by heat or high frequency welding technique to a thermoplastic sheet by applying thereto, over at least those areas of it to which the sheet is to be caused to adhere, a coating of a welding aid comprising a thermoplastic synthetic resin which is readily weldable to itself or another thermoplastic synthetic resin and which adheres strongly to polyurethane, the thickness of the coating being such as not to seal the porous surface of the polyurethane to which it is applied.  The welding aid may be applied in the form of a solution in a volatile solvent or an aqueous emulsion, the solvent or the liquid phase of the emulsion being allowed to evaporate or being driven off before the welding is effected; in the form of a plastisol; or in powder form which is caused to adhere to the polyurethane foam by the welding operation.  The welding aid or an essential ingredient thereof may be polyvinyl chloride; a copolymer of vinyl chloride with vinyl acetate, polyvinylidene chloride or a copolymer of vinylidene chloride with vinyl chloride or acrylonitrile.  The welding aid may also include a colouring pigment to assist in identification of those areas of the polyurethane surface to which it has been applied.  A sheet of a thermoplastic, e.g. polyvinyl chloride, may be welded to the coated surface, or only at selected areas of the surface, or two sheets of polyurethane foam to each of which has been applied a coating of a thermoplastic synthetic resin, as above, the two coated surfaces may be caused to adhere to each other, by heat or high frequency welding techniques.  The welding aid may be applied by brushing, spraying, roller, reverse roller or gravure roll coating.

An electromagnetically actuated valve has a rectangular block 1 with a bore 8 opening into a threaded counter-bore 9, 10 at each end into which bore open a pressure inlet groove 11 and working grooves 12; the counter bores 9, 10 are connected to an exhaust port. The bore 8 houses a spool 15 with lands 16, each reduced diameter end of the spool being housed in a recess 37 in the armature 35 of the adjacent electromagnet 2, 3 and connected thereto by a pin 38, the pin hole in the spool being recessed at each end so that the effective axial length of the hole is small thus providing a limited degree of universal coupling and lost-motion. A similar effect is realized by elongating the pinhole. The electromagnets are threaded into the counter-bores and have cores incorporating shading-rings. The spool is centred by spring 44 acting against cups 42 whch are ported and form part of the path for exhaust fluid.
