IPC: A22B3/02
Abstract: 105,834. Cash, C. July 8, 1916. Breech actions, hinged breech-block.-A pistol for slaughtering cattle &c. is provided with a breech-block A, pivoted at B to a breech-plate C rigid with the barrel D, and provided with a step A' which engages a corresponding step on the breech-piece so that when the explosion takes place the thrust is upon the step and not upon the hinge. The trigger M is connected to a spring stop J which engages a projection K on a trailing setting-member G, which is provided with pins H travelling in a slot I of the shape shown, and whose upper end is caused to compress the actuating spring F of the pistol when the breech is opened as shown in Fig. 3, and afterwards closed. The tail of the setting-member engages a hook P at the end of a cartridge extractor N as the breech is opened, and the extractor is returned to its normal position, when the hook P is released, by a spring O. The breech is held in a locked position by a spring bolt L.

Title: Process for the production of metallic sulphates, and ammonium sulphite and sulphur or ammonium thiosulphate
IPC: C01B17/96
Filed: 1936-04-14
Abstract: Metallic sulphates, for instance zinc, copper, or lead sulphates, are obtained from their sulphides or sulphide ores by heating the latter at say 150--440 DEG  C. in admixture with ammonium sulphate or bisulphate.  The volatilized products of reaction, comprising ammonium sulphite, sulphur, and free ammonia may be passed first into a jacketed condenser maintained at 100--150 DEG  C., where the ammonium sulphite and sulphur are condensed and combine to form ammonium thiosulphate, and then to a scrubber to recover free ammonia.  Alternatively the thiosulphate may be collected in solution by contacting the volatilized reaction products with hot water, or the sulphur may first be condensed at 200--350 DEG  C. and ammonium sulphite be separated at a lower temperature.  The reaction may take place continuously in a mechanical muffle furnace, and in order to assist in excluding air a little free sulphur may be mixed with the charge.  Specification 430,945 is referred to.

Title: Improvements in or relating to direction finding radio receiver systems
IPC: G01S1/02
Filed: 1938-04-07
Abstract: 492,643. Directive wireless signalling. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE. April 7, 1938, No. 10729. Convention date, April 7, 1937. [Class 40 (v)] Relates to a " homing " installation of the kind in which pick-up from a directional aerial is combined through a reversing switch with that from a non-directional aerial, the output from the receiver being fed through a synchronous reversing - switch to a directreading indicator. According to the invention, the single-frame voltage is so combined with that from the non-directional aerial that the 180‹ ambiguity is removed by the fact that at the correct zero point the indicator needle moves in the same direction as the frame aerial, whilst at the false zero it moves in the opposite direction. The arrangement is shown in Fig. 1, the single frame aerial R and vertical aerial A being combined through the receiver E in the indicator T. In Fig. 2, the frame voltage is shown at R and the positive and negative " vertical voltages at +a and -a respectively. The different movements of the indicator needle depend upon the fact that at the 90‹ zero the curve R is rising, whilst at the 270‹ zero it is falling. In the same way a single auxiliary frame aerial is used to resolve the 180‹ ambiguity in an Adcock aerial, or in a system in which two parallel frames are connected in opposition to prevent night effect. The four-point characteristic of a spaced doubleframe is shown at R in Fig. 3, whilst the response of the continuously-rotating single frame is shown at A and Al respectively. The effect of the reversing switches on the indicator reading is shown in Fig. 3a. The needle only passes " across " the zero at 180‹ and at 360‹, and at only one of these points does it " follow the movement of the frame aerial.

A surplus pressure or vacuum relief valve comprises a housing 2, 3 divided by a flexible diaphragm 5 into two chambers, one of which has one or more ports 10 opening out of the chamber and another port 12 controlled by a valve member 14 which is connected by a stem 15 to the diaphragm 5, the other chamber being permanently in communication with that side of the valve member 14 which is outside the housing via a passage 16 extending through the stem 15, the valve being spring-urged towards the closed position. When used as a surplus pressure-relief valve, the valve port 12 communicates with the interior of a vessel 1 to be maintained at a predetermined pressure above atmosphere, so that the vessel is relieved to atmosphere through the ports 10. In an inverted position of the valve wherein the ports 10 open into the interior of the vessel 1 and the valve port 12 opens to atmosphere, the valve performs the function of a vacuum relief valve to limit the degree of vacuum in the vessel 1.

[Class 46] Filter bodies consisting of superposed layers of fine and coarse glass particles are made by depositing fine particles from a liquid suspension of slurry on a layer of coarse sintered particles under conditions which expedite settling and promote random contacts of the particles and drying and baking the deposited layer. A slurry of fine particles may be made in anyl-acetate, acetone or trichlorethylene and kept in a state of agitation and the coarsegrained plate lowered on to the surface of the slurry. Liquid is drawn by capillary attraction into the plate leaving a film of fine powder on the surface, the thickness of the film being controlled by the temperature and the time of immersion. In the case of water of other ionising liquid in the slurry, the pH value is a controlling factor. Graphs are given showing indirectly the influence of some of the controlling factors.
