Title: Improvements in or relating to self-holding electro-magnetic relays
IPC: H01H51/01
Filed: 1952-09-12
Abstract: 724,034. Electromagnetic relays. LICENTIA PATENT-VERWALTUNGS GES. Sept. 12, 1952 [Sept. 14, 1951; Oct. 29, 1951], No. 22933/52. Class 38 (5). A self-holding electromagnetic relay in which, after a transitory excitation, the armature 2 is held in the working position by the residual magnetism of the magnetic circuit has the contact surfaces between the core 1 and the armature 2 so designed that the ratio of the area of the actual contacting surfaces to the mean cross sectional area of the magnetic circuit is approximately equal to the ratio between the remanent flux density and the flux density at saturation. The contact surface may be formed by a projection 4 raised from the normal surface of the armature, or alternatively it may be a stud or a screw inserted in the armature and/or the core. In order to provide good wearing contact surfaces, a material such as stainless steel may be secured to the core and armature and as protection against oxidization the surface may be plated with nickel, chromium or the like or coated with a hard lacquer. To return the relay to the unoperated position a counter-excitation in the order of 10 to 50 per cent of the original excitation is applied.

In a motor vehicle hydrostatic transmission of the kind described in the parent Specification wherein an engine driven fixed displacement swashplate pump 11 having a fixed cylinder block and rotary swash plate delivers to a hydro-pneumatic accumulator 17 until the pump delivery pressure is equal to the pressure in the motor circuit 14, 15 whereafter the remainder of the pump delivery is supplied through a network of non-return valves 16 and a reversing valve 18 to a fixed displacement motor 13, the load on the pump 11 is reduced when the pump speed is below a predetermined value by providing a reciprocable column of liquid in a duct 98 between the pump supply passages. At low pump speeds the pump delivery which during each half cycle acts on opposite sides of the liquid column causes the latter to reciprocate. As the pump speed rises the amplitude of the reciprocation is reduced and the delivery pressure and load on the pump rises thereby charging the accumulator and delivering to the motor circuit. A relief valve 93 is provided in the motor circuit in series with a valve 94 which opens when the engine speed or accelerator pedal position is below a predetermined value.

Title: Manufacture of new benzene sulphonylguanidines
IPC: C07C311/64
Filed: 1942-11-30
Abstract: p-Aminobenzene-sulphonyl guanidines substituted in the guanidine residue are prepared by reacting an S-alkyl benzene-sulphonyl pseudo-thiourea, containing in the para-position an amino group or a substituent convertible thereto by hydrolysis or reduction, with a compound containing an amino group or, when the parent material contains an N-alkyl substituent in the thiourea residue, with ammonia, the aforesaid convertible substituent, if present, then being converted to an amino group. The reaction may be effected in presence of water or an inert solvent such as ether, dioxane, alcohol, acetone, benzene, toluene, xylene, chlorbenzene, nitrobenzene or tetrachlorethane. The substituent group, which is converted to an amino group by hydrolysis or reduction in known manner, may be acylamino, nitro, azo or azomethine.  The compound containing an amino group may be an aliphatic, aromatic, alicyclic or heterocyclic amine, for example methyl-, ethyl-, ethanol-, dimethyl-, diethyl-, propyl-, benzyl- and p-hydroxycyclohexyl-amines, which may be substituted by basic or acid groups such as diethylamino, carboxy or sulpho. In examples: (1) p-acetylaminobenzene sulphochloride is heated with ethyl-pseudo-thiourea hydrobromide in pyridine and the solution poured into water to precipitate N - (p-acetylaminobenzene-sulphonyl) - S - ethyl - pseudo-thiourea which is heated with aqueous dimethylamine to yield p-acetylamino-benzenesulphonyl-dimethylguanidine which on hydrolysis with hydrochloric acid gives the p-amino compound; (2) the N-(p-acetylaminobenzenesulphonyl) - S - ethyl - pseudo - thiourea of (1) is hydrolysed with hydrochloric acid to the corresponding p-aminobenzene compound which yields p - aminobenzene - sulphonyl - diethyl - guanidine with aqueous diethylamine.  Replacing diethylamine by p-aminocyclohexanol yields the p-hydroxy-cyclohexyl-guanidine derivative.  In analogous manner the n-propyl-, ethyl-, n-butyl-, isobutyl-, n-heptyl- and diethylaminoethyl-guanidine compounds may be obtained.  The sample furnished under Sect. 2 (5) is of p-aminobenzene-sulphonyl-dodecylguanidine.

Abstract: 1,006,541. Joints for concrete roads. A. SHAW. Sept. 18, 1961 [July 13, 1960], No. 24432/60. Heading E1G. In a reinforced concrete road a joint which allows contraction of the concrete during maturing comprises reinforcing rods 14 each embedded for part of its length in one part 12 of the concrete and projecting into a sleeve 15 embedded in an adjacent part 11 of the concrete so that relative axial movement between the rods and sleeves may take place during shrinkage of the concrete. The outer ends of the sleeves are sealed around the rods 14 by rubber rings 16. When shrinkage is completed, the sections 11 and 12 are locked together by injecting a resin or cement grout into pipes 18 leading to the inner ends of the sleeves 15. A temporary packing of e.g. expanded plastics material in the space 19 between the sections is removed and replaced by grout 22 which may be covered by a layer 23 of resin sealing compound. The assembly of rods, sleeves, rings and grout pipes may be prefabricated and supported clear of the sub-base 13 by steel members (not shown) during casting of the concrete. Flat hydraulic jacks may be inserted in the space 19 to force the sections 11-12 apart if the joint is to be locked before the concrete has fully matured. In an alternative embodiment, Fig. 3, in which the concrete is cast continuously, each rod 34 enters its sleeve 35 at the point 32 between the ends of reinforcements 31 where a transverse crack will develop as the concrete shrinks. Angle members 36, 36a support the rod and sleeve assembly 33, 33a respectively, and assist in locating the plane of cleavage in the concrete. The assemblies 33, 33a are also wired at 37 and 41 to the reinforcement 31 and mesh strips 38, 39 respectively. The joint is sealed as before through grout tubes 29 after the removal of polythene sections 28. The rods 34 may be of e.g. helical form.

Abstract: 751,694. Photographic cameras. LYTAX WERKE GES. Aug. 24, 1954 [Sept. 18, 1953], No. 24587/54. Class 98 (1). An arrangement for exploring the interior of a hollow body photographically comprises a camera rotatably mounted in a bushing, means for temporarily fixing the bushing within the hollow body, and a gear member fixed relatively to the bushing and co-operating with another gear member mounted on the camera for driving a film feed mechanism of the camera when the camera is rotated relatively to the bushing. As shown, the central tubular portion 1a of the camera 1 is rotatably mounted in a bush 2 attached to the inside of the hollow body 4 by electromagnets 3. The bush 2 carries a bevel gear 5 which meshes with a gear 6, on the camera body, from which through the train 7, 8, 9, 10 the film driving roller 11 is driven as the camera is rotated by the shaft 1b. A spring-loaded pivoted member 16 presses on the wall of the body 13 through an aperture 13 in the camera body, the member 16 itself having an aperture 13a through which by reflection from an inclined mirror 14, an image of the wall is formed on the film by the lens 15, the wall being illuminated by lamps 18 in shields 19. The lens mount is coupled to the member 16 by a bell-crank 17 to maintain focus for different diameters of the hollow body. The film drive, in an alternative embodiment, includes a friction drive of variable ratio also coupled to the member 16. The bush 2 may be secured to the body 4 by clamping instead of by electromagnets.
