Title: Means for reducing the amount of smoke evolved during the combustion of inhibited propellant charges
IPC: F42B29/00
Filed: 1963-07-01
Abstract: 1,009,975. Propellent charges. BOMBRINI PARODI-DELFINO S.p.A. July 1, 1963 [July 21, 1962], No. 25997/63. Heading F3A. To reduce the smoke produced during burning, a charge comprises a layer of propellant containing an oxidizing inorganic salt between the main body of the charge and an inhibiting coating. The oxidizing salt may be an alkali metal nitrate or an alkaline earth metal nitrate, e.g. barium nitrate. A doublebase propallant consisting of nitroglycerine 37%, nitrocellulose 53À5%, nitrodiphenylamine 1À5%, organic lead salts 3%, and plasticizers 5% (all parts being by weight) is coated with the same composition containing in addition 20% barium nitrate before layers of ethylcellulose tape are applied. The charge may be formed by introducing a cylinder of thin sheet material into a mould and pouring the nitrocellulose powder into the cylinder. Nitrocellulose powder containing the oxidant is poured into the annular space around the cylinder before removal thereof and subsequent addition of a gelatinizing liquid containing nitroglycerine. Alternatively the oxidant containing layer may be formed into a sheet which is wrapped around the main body of the charge.

Abstract: 495,591. Supply systems for discharge lamps. GENERAL ELECTRIC CO., Ltd. (Patent-Treuhand-Ges. f³r Elektrische Gl³hlampen) Sept. 28, 1937, No. 26263. [Class 38 (iv)] A high pressure metal vapour lamp is connected in series with an iron or like wire, having a positive temperature coefficient of resistance, in an atmosphere of a gas such as hydrogen or helium having high thermal conductivity, so proportioned that the voltage across the wire is less than 25 per cent of the total voltage and the wire acts as substantially the whole of the stabilizing impedance for the lamp but provides substantially no light. By this means improved total efficiency is obtained. The metal in the discharge lamp may be mercury, all the mercury being evaporated in. normal operation. The iron wire may be in the jacket of the discharge lamp and may be protected from overload during starting by a series protective resistance which is cut-out by a further resistance having a high negative temperature coefficient connected in parallel with it and heated by the protective resistance, the iron wire or the discharge separately or together.

Convention dates, Sept. 21, 1934, Oct. 31, 1934, March 25, 1935, and March 25, 1935. [Class 38 (v)] [Also in Group XXXVI] In a plug coupling combined with a switch, the movable member carrying the sockets and the movable switch contacts is connected with the casing by a flexible corrugated metal tube which thus isolates the switch contacts to prevent ignition in a firedamp atmosphere. In the form shown in Fig. 1 the movable plate i carrying the sockets m and the contacts k co-operating with the fixed contacts h is mounted in the casing a by means of the tube n. The plate is urged to the right by a spring j, and the plug c when inserted in the neck b and pressed home is retained by a bayonetfastening the pins f of which are on a sleeve rotatable on the plug. In the modification shown in Fig. 4 the movable member consists of a block i fitted with the socket bushes k terminating in spring-mounted hemispherical contacts p. The stationary contacts h are tubular and contain spring-supported tungsten or platinum tips x. To ensure gas-tight joints the metal casing a and the metal ring s soldered to the tube n are fixed to the insulating members q, i respectively by heat-shrinkage. The switch chamber may be filled with carbon dioxide for arc-quenching.

Title: A guide device for tipping floor of stunning pen or slaughter house
IPC: A22B5/02
Filed: 1921-10-06
Abstract: 188,879. Blunden, L. E. Oct. 6, 1921. Slaughtering.-In a stunning-pen the animal is shielded from view of animals awaiting slaughter, and means comprising a tilting floor interconnected with side walls, are provided automatically to eject the carcase from the pen. As shown in Figs. 3 and 4, two movable side walls 6 are connected to the floor 5 by chains 7 passing over pulleys 8 and attached to shackles 23, 24 on the walls and floors respectively, the floor thereby being tiltable in either direction. The floor 5 is provided with pins 20 which act as pivots for the floor or slide along angle bar guides 19 according to the direction of tilting. The walls are locked by the engagement of bellcrank plates 26, pivoted at 27, with fixed stops 28 on the framework 1 in which the side walls are slidably mounted, the plates 26 being operated by toggle-levers 30, the weight of which tends to make the engagement. Normally the togglelevers sag below the horizontal, ropes being attached to eyes on the links 32 whereby the operator on the platform 18 may break the toggle upwardly, release a side, the weight of the carcase causing the floor to tilt into the inclined discharging position and the side wall to rise to allow the carcase to be ejected. Preferably the weights of the floor and side walls are so arranged that they return automatically to the operative position. The animals walk up an inclined ramp which leads to the entrance door 4 and which passes through the dividing-wall between the lairage and the finishing-room. In a modification, one wall only is movable, the floor is mounted on a fixed pivot and tilts in one direction only and the wall is locked by a lever which engages the top of the sliding wall. A weight on the lever tends always to throw the lever into the locking position. The pen may be elevated so that the animals may be discharged into trucks.

Abstract: 1399482 Amplified photographic image EASTMAN KODAK CO 7 June 1972 [7 June 1971 14 Oct 1971] 26632/72 Heading G2C, G2H The production of an amplified photographic image involves an imagewise redox reaction between an oxidising cobaltic complex and a reducing agent (e.g. developer) in the presence of the image as catalyst. The catalyst may be of silver, gold or platinum. It may be imagewise inhibited. The complex may be present in the photographic material or the developer. The photographic material may be monotone or multicolour. An imagewise change in light value may be produced by the redox reaction, by further reaction of one redox product with the other or another material or by inhibition by one redox product of a reaction of another material. Alternatively, a tanned'gelatine image produced by the redox reaction followed by washing may be dyed. The amplified image may be transferred to or be produced in a receiver sheet or may be supplement or replace the original image. Examples given include treatment of an exposed silver halide emulsion layer containing a colour coupler with a solution of colour developer and complex optionally after a normal or reversal black and white development. An electro-photographically produced toner image comprising activated carbon may be intensified by treatment with a solution containing a reducible cobaltic complex, colour developer and colour coupler.
