Title: Improvements in electromagnetic overload circuit-breakers
IPC: H01H71/68
Filed: 1922-01-30
Abstract: 175,965. Krupp Akt.-Ges., F. Feb. 24, 1921, [Convention date] Electromagnetic switches; contacts.-In a circuit-breaker, movable contacts E, F are kept tightly closed by means of springs J, H pressing them together. The operating-coil C, having only a few turns, acts to move the armature B in the direction of the arrow z and, through the lever G<1>, G, the contacts E, F in the direction of arrow x. Contact F is free to travel through a distance f<4>, but when the pull on the armature B is sufficiently large, the spring J is overcome and the contacts are separated. Once separated, the coil D, which is arranged in a shunt circuit (and has many turns), keeps them apart. To re-close the contacts, the switch c<2> is opened so as to deenergize coil D. In the Specification as open to inspection under Sect. 91 (3) (a), " power accumulators " take the place of the springs J, H. This subjectmatter does not appear in the Specification as accepted.

Title: Improvements in or relating to latex undergarments and method of manufacture
IPC: A41C1/04
Filed: 1954-01-29
Abstract: 759,061. Corsets. INTERNATIONAL LATEX CORPORATION. Jan. 29, 1954 [Feb. 13, 1953], No. 2736/54. Class 141. [Also in Group V] To reduce sliding of garments over moulded undergarments, and to reduce static electricity effects, the surface of the deposition former 18, Figs. 2 and 5, has alternating stripes 20, 22 which produce on the surface of the deposited undergarment 10, Fig. 1, corresponding alternating stripes 12, 12<1> of differing texture. The stripes 12 are glossy and smooth, and the stripes 12<1> are velvety, lustreless and smooth. The former 18 may be made by selectively etching, sandblasting or abrading an ordinary smooth former, this etching &c. producing velvety, lustreless, smooth stripes 22 and leaving glossy smooth stripes 20. If the former is dipcoated with latex coagulant before it is dipped in latex, more of the coagulant will cling to the lustreless stripes 22 than to the glossy stripes 20, and this will result in a diminished sharpness of reproduction of stripes 22 and also a thickening of those stripes. Cotton filaments 24 may be embedded in the outer surface of the garment (later to become the inner surface by turning inside out) as described in U.S.A. Specification 2,636,173. Ventilating holes 30 are provided in the garment.

Fluid-pressure.-A pneumatic relay suitable for the brakes of motor vehicles comprises a singleacting piston 3 witiiin a cylinder 1, combined with a longitudinally movable valve casing 10, outside the cylinder, containing oppositely disposed valves and having connections to a source of vacuum and to atmosphere, whereby one side of the piston or both sides may be subjected to vacuum. The casing 10 is actuated directly by the operator, and a sleeve in the casing, which actuates the valves, is connected to the operated part. The valve casing is actuated, for example by the brake pedal, and the piston is connected to the brake &c, to be actuated. Lost motion may be provided in the connection between the piston and the brake &c. so that the brake may be actuated by the operator's physical force. without moving the piston. In a modification. both sides of the piston may be subject to atmospheric pressure in the neutral position. The cylinder 1 is connected with the engine intake manifold by a suction pipe 62 provided with a restricting valve 67 and a check valve 65. The front and rear of the cylinder are also connected by flexible pipes 62<a>, 66 with the valve casing and the interior of a valve sleeve 20 respectively. The piston rod 5 and the sleeve valve 20 are connected by rods 73, 31, and arms, with a rock shaft 75 by which the brakes are applied. The rod 73 may be connected with the rock shaft by a pin and slot, giving lost motion. The brake pedal is connected to the valve casing by a rod 25, and the brake pedal and brakes are provided with retracting springs 89, 72<a>. The valve casing is provided with an air inlet 11 and contains valves pressed apart on the sleeve by a spring 50, the relative motion being limited by collars on the sleeve. Relative motion between the sleeve and the casing is limited in one direction by abutment of the sleeve end on the casing, and in the other direction by engagement of a collar 28 with an adjustable screwed sleeve 21. Ports 27 in the sleeve connect the space between the valves with the sleeve interior. In the neutral position shown, both sides of the piston are open to vacuum. If the pedal is depressed, the valve casing is drawn in the direction of the arrow, and the right-hand valve is first closed, and the left-hand valve then opened, allowing air to pass through the sleeve to the right-hand of the piston and force it back to an extent corresponding with the movements of the valve casing and the pedal. In a modification, the valve is directly open to the engine suction, and one end of the cylinder is connected through the sleeve with the suction when the valve casing is moved bv the operator while the other end is open and therefore always subject to air pressure. The opening of the valve may be restricted to regulate the inlet of air to the engine and prevent stalling. Specifications 262,450 and 259,189 are referred to.

Title: Preparation of cyclohexanol and cyclohexanone
IPC: C07C29/50
Filed: 1964-01-27
Abstract: In a process for preparing cyclohexanol and cyclohexanone by oxidation of cyclohexane in the liquid phase with a gas containing molecular oxygen, non-converted cyclohexane is separated from the oxidation product, esters present in the oxidation product are saponified with an aqueous alkaline solution, and cyclohexane is added to the reaction mixture, preferably in an amount of 15-40% by weight with respect to the amount of oil phase to be separated off and, subsequently, cyclohexanol and cyclohexanone are recovered from the resulting oil phase after partial or complete separation therefrom of the aqueous phase.  In an example the oxidation product, obtained by oxidation of cyclohexane with air-oxygen, from which after separation of the residual gas of the oxidation, the non-converted cyclohexane is removed by distillation at atmospheric pressure, is introduced into a reaction vessel and an aqueous solution of sodium carbonate added, followed by an aqueous solution of sodium hydroxide, and the mixture is stirred.  Cyclohexane is then mixed with the reaction mixture at a temperature of 40 DEG  C. after which the water layer is separated from the oil layer and the organic products contained in the water layer are extracted with cyclohexane and the extratc added to the oil layer.  The latter is washed and distilled and cyclohexanol and cyclohexanone separated together from the higher-boiling residue in a distillation column.  Specification 890,137 is referred to.

Title: Improvements in and relating to the manufacture of gun tubes, suitable for use in the construction of howitzer and like guns and for the linings of wire-wound and other guns
IPC: B21C37/15
Filed: 1918-03-01
Abstract: 142,146. Hadfield, Sir R. A., Jack, A. G. M., and Clerke, A. B. H. March 1, 1918. Ordnance; tubes.-Guns or gun tubes are made from cast billets by piercing, drawing, or turning and boring, and heat-treatment. A tapering grooved billet as described in Specification 4228/15, [Class 83 (i), Casting &c. metals], is cast, the head is cut off, and it is roughly turned to a uniform diameter without removing the grooves completely. After heating, it is inserted in a matrix h, Fig. 19, which it fits. The billet is then pierced and extruded by an hydraulic plunger n while supported by a plug k and ribbed abutment m. After the return of the plunger n and removal of the abutment m, the billet is ejected by an hydraulic pusher p. The heated billet is then reduced in diameter in a number of stages by pushing through single or multiple dies r by mandrels n<1>, Fig. 21, of smaller diameter than the hole in the billet or tube acted on. To ensure centring, each successive mandrel is blunter than the preceding one, and to avoid driving the mandrel through the end a<2>, this may be cooled before and during the draw. A stripper is slipped between the last die of a set and the tube end, and, when the mandrel retires, the tube falls into the cradle f. For facilitating the placing of the tube on the mandrel, this may be ball-jointed at t and raised, as shown in Fig. 24, by an hydraulic device u on a carriage w. The first die of a set may merely serve as a guide. After drawing, the tube is roughly turned and bored to the required finished dimensions, and, in the case of a gun lining, the closed end is cut off. The tube is finally hardened and tempered.
