Abstract: 446,736. Automatic regulation; converting. KRAMOL1N, L. L. DE, 25, Nassauischestrasse, Wilmersdorf, Berlin. July 27, 1934, No. 22037. [Classes 38 (ii) and 38 (iv)] [See also Group XXXVI] The temperature of a heating resistance having a high temperature coefficient is controlled by varying the current supplied to it by means of a gas or vapour discharge device the control potential of which is varied in accordance with the p.d. across whole or part of the resistance, so that the temperature of the resistance is maintained constant irrespective of the temperature of its surroundings. The discharge tube R is of the continuously controlled type and is connected directly in series with the heating resistance W. It is controlled by an external displaceable control electrode S. Alternatively an internal grid supplied through a variable condenser may be used and the control potential may be taken from a tapping between two heating resistances of different temperature coefficients connected in series with the tube. The discharge tubes may have both main electrodes activated so that control is obtained in alternate half cycles when A.C. is supplied to the resistance. Alternatively two such discharge tubes controlling alternate half cycles may be connected in series and their grids connected to suitable points on the resistance. The discharge device may be incorporated in the apparatus plug and its illumination may be used through pyrometric means to measure the current in the circuit and the temperature of the resistance. In place of continuously controlled discharge devices, discontinuously controlled valves of the " Thyratron " (Registered Trade Mark), type may be used. Specification 446,797 is referred to.

Title: An improved method of, and apparatus for, separating solids and liquids in sewage and polluted water
IPC: C02F1/24
Filed: 1937-08-11
Abstract: 491,623. Aerating sewage etc.; gravityseparation apparatus. McILLERON, R. C. Aug. 11, 1937, No. 22120. Convention date, May 14. [Class 111] Solids and liquids in sewage and polluted water are separated by first aerating the sewage liquid or water to effect saturation or partial saturation with air at a predetermined pressure, and then effecting a drop in the pressure such that air is evolved to produce movement of the solids upwardly relatively to the liquid, the separated solids and liquid then being drawn off from one another. The sewage is fed from a preliminary settlement tank 5 into a launder 4 communicating by a pipe 2 cock 12 and Venturi tube 8 with a pressure or aerating vessel 1, this vessel being situated at a sufficient depth to give the desired pressure to the sewage liquid. The Venturi tube is provided with air inlets 9 through which air is drawn into the liquid the supply of air being controlled by a cock 11. The chamber 1 is provided with a motor driven impeller 14 by which the liquid is drawn up a tube 18 and flung at high velocity against the sides of the vessel, thus becoming saturated with air. The air-saturated liquid passes upwardly through the outflow pipe 3, which is of less cross-section than the pipe 2, at such a velocity that the solids are carried therewith up the pipe to a settling tank 7. As the liquid rises in the pipe some of the air dissolved therein is freed due to the reduction in pressure and ascends to the surface in the form of small bubbles carrying with it the floatable solid particles. These accumulate in a sludge compartment 25 of the tank 7 and are run off at intervals through a pipe 26, the clarified effluent and heavy solids being drawn off from a chamber 22 and 28 respectively. In a modification the pressure chamber, instead of being provided with an impeller, is provided with a series of plates over which the liquid flows to expose a large surface to the air and in another a circulating pump is provided by which the liquid is caused to flow over frusto-conical baffles for the same purpose. Instead of being produced statically the pressure on the liquid in the chamber may be obtained by the use of air compressors &c.

Abstract: 784,850. Controlling hydraulic apparatus. OVRETVEIT, K. A. March 2, 1953 [Sept. 3, 1952], No. 22190/52. Class 69 (2). In an hydraulic circuit, including a constant output pump and a motor, a valve for controlling the rate of flow to the motor comprises a control member associated with and adapted to move across at least one mainport, a by-pass channel and auxiliary port being associated with at least the one mainport, and a non-return valve in said by-pass being adapted to open when said mainport is obstructed. A rotary valve, Fig. 5, of the Figure accompanying the Provisioral Specification, has a port 4 connected to the outlet of a pump and a port 6 to the pump inlet. Ports 10, 12, 14 are connected to the inlets of three working chambers of a multi-rotor motor and a port 18 is connected to their outlets. A port 10 is connected to the inlet of a fourth working chamber of the motor and a port 20 to its outlet. A member 22, having two abutments 24, 26 is rotatable on a shaft to control the fluid supply from the pump to one or more of the working chambers in the forward direction of the motor or to one or all of the working chambers in the reverse direction. As shown the abutment 26, which is narrower than the width of the ports, is partially obstructing the port 14, so a relief valve 34 communicating with the port 16 opens to prevent a vacuum forming. Ports 52, 53 and recesses 50, 51 are provided in the member 22 for balancing the pressure thereon. There may be a number of constant output pumps supplying one motor. In a modification, Fig. 1, a piston member 22 has heads 24, 26 which co-operate with ports 4, 6 connected to a pump and ports 10, 16, 20, 18 connected to a motor or motors as before. A relief valve 62 closing a by-pass 66 to the port 6 rests under the action of gravity, a small passage 76 communicating the pressure in the port 6 to the top of the valve stem.

[Class 9 (i).] Relates to sensitive percussion fuzes of the kind in which a free mass is arranged between the fuze casing and a telescopic body containing the striker and detonating cap, and in which the said body is held extended by a spring and by means which are automatically removed by the flight of the bomb. According to the invention, two freely arranged masses are located one at each end of the fuze casing and bear against discs formed integral with the telescopic body. As shown in Fig. 1, a tubular stem 9<1> containing the detonating cap 12 is arranged to slide within a stem 8<1> containing the striker 11, the said stems being normally held extended by a spring 10 and slide 13. The stems 8<1>, 9<1> are formed integral with discs 8, 9 respectively, and between these discs and the fuze casing 4 are disposed two hemispherical masses 8<11>, 9<11>. The fuze casing is secured to the neck 2 of a bomb 1 containing the explosive charge. To the slide 13 is hinged, on a pin 15, a casing comprising two mutually hinged segmental shells 14o, 14, Fig. 2, which fit over the nose 5 of the fuze casing and are normally secured thereto by a pin 16. In operation, the pin 16 is withdrawn when the bomb is thrown. During the flight of the bomb, the shells 14o, 14 open out under the action of the air and withdraw the slide 13 from the fuze casing. On concussion, the masses 8<11>, 9<11> move laterally across the discs 8, 9 and thereby cause axial displacement of the stems 81, 91, which approach against the action of the spring 10. The masses 8<11>, 9<11> are made of a heavy, easily fusible material, such as an alloy of lead and bismuth, and they may contain explosive charges 80, 90. The discs also may be filled with explosive substances.
