Title: Improvements relating to mechanisms for controlling valves or the like
IPC: C02F1/42
Filed: 1946-03-01
Abstract: 615,336. Manually-actuated multiple-way valves. PERMUTIT CO., Ltd., and LAWRENCE, H. S. March 1, 1946, No. 6482. [Class 135] [Also in Group I] A selector mechanism for controlling a plurality of valves comprises a number of valve-actuating plungers guided for parallel axial movement, means for moving all the plungers to a forward position, each against an individual restoring force, and a selector device, movable when the plungers are forward into different settings, in each of which selected plungers are allowed to move back while the others are maintained forward. Each of the seven operations involved in the recharging of the exchange materials of a watertreating apparatus (see.Group I) corresponds to one setting of a hollow rotatable cylinder 14, Figs. 1 and 2, provided with rows of holes 28 controlling the selective actuation of seven diaphragm valves 13, the latter being closed on to ports 15 by the forward movement of the plungers which are formed by telescoping parts 16, 18, pressed apart by springs 20. On rotation of a handle 26, a striker bar 21, in abutment with flanges 25 on the parts 18, forces the plungers forward, thus compressing the springs 20 and moving the parts 18 clear of the holes in the cylinder which may then be rotated to any desired setting. Release of the handle 26 permits the water pressure on, and the resilience of, the diaphragm valves, to move back the plungers positioned opposite the holes 28, whilst the remaining plungers are maintained forward by the springs 20 forcing the parts 18 into abutment with the surface of the cylinder. In a modification, the striker bar 21, Fig. 8, is actuated by a cam slot in a disc 45 which may be oscillated manually, or by a hydraulic piston or by an electric motor. The disc is in lost-motion connection with a ring 53 carrying a pawl 54 engaging a ratchetwheel 55 rigidly attached to the cylinder 14, so that one complete oscillation of the disc moves the selector mechanism to the next setting.

Title: Improvements in or relating to means for controlling an auxiliary air supply to internal combustion engines
IPC: F02D9/00
Filed: 1930-03-03
Abstract: 345,072. Auxiliary air admission devices. WEDGE, E. L., 235, Tettenhall Road, Wolverhampton, and BLACKHAM, H., 22A, Evans Street, Willenhall, Staffordshire. March 3,1930, No. 6882. [Class 7 (ii).] Auxiliary air, which may be drawn in adjustable proportions from the engine casing or the atmosphere, or from both sources, is admitted to the induction pipe between the carburetter and engine through a valve which is moved conjointly with the main throttle valve, the air control valve being so arranged in relation to the throttle that it reaches its maximum opening when the throttle valve is in the position for normal running and closes as the throttle is moved towards either side of the normal. Passages E, F admit air to a chamber B from the engine casing and the atmosphere respectively, the proportions being regulated by throttles e, f controlled by a wire g; the setting of the valves is such that as one opens the other closes. The chamber B communicates with another chamber, C, through a valved orifice d; outlets q lead from the chamber C to the induction manifold. A valve J is adjustably fixed to a rod H which passes out of the chamber B and which is so connected to the main throttle control that the valve J is moved away from the orifice d as the throttle is opened. A second valve M, slidably mounted on an extension of the rod H, is moved by a spring m to close the orifice d as the normal running position of the throttle is passed, the arrangement permitting further opening movement of the throttle after the valve M has seated. In a modified construction the valve M is adjustably fixed to the rod H whilst the valve J is slidably mounted thereon.

Filed: 1954-03-10
Abstract: 781,175. Protective arrangements. SIEMENS BROS. & CO., Ltd. March 7, 1955 [March 10, 1954], No. 6934/54. Class 38 (5). [Also in Group XL (c)] In a fault indicating system for a thermionic valve circuit a test point in the anode cathode path of each valve is connected through a cold cathode gas discharge tube to a common fault indicating line so that the change of potential of the point when a fault occurs causes the gas discharge tube to become conductive and operate the fault indicator. In Fig. 1 the junctions of the de-coupling components R12, C1 of a number of thermionic valves are connected through gas discharge tubes N1, N2, to a potentiometer R1, R2, R3, R4, R5 to the grid of a valve V3. If the current in valve V1 or V2 fails the corresponding gas discharge tube becomes conductive, thus causing the left hand half of valve V3 to conduct and the right-hand releases and operates the fault indicator.

Title: Improvements in the production of phenolic condensation products and treatment of materials therewith
IPC: C08G8/28
Filed: 1945-01-25
Abstract: A stable semicondensate suitable for impregnating paper (see Group VIII) is made by mixing a phenol with an aqueous solution of formaldehyde in presence of an amount of caustic alkali acting as catalyst for the condensation which is not less than 3 per cent of caustic soda or than the equivalent amount of other caustic alkali (calculated on the weight of material in the mixture other than water), such conditions of heat conservation and concentration of formaldehyde being employed that the reaction mixture can heat itself to a temperature of at least 65 DEG  C., and the reaction is interrupted after a temperature of 50 DEG  C. has been reached but before a temperature of 65 DEG  C. has been exceeded and while the reaction mixture, when containing an amount of water corresponding to the use of 40 per cent formaldehyde in the condensation, has a viscosity of 12-30 centipoises measured at 20 DEG  C.  The reaction is preferably interrupted when the viscosity at 20 DEG  C. is 12-16 centipoises, or when the temperature is 57-62 DEG  C. or 59-61 DEG C., and the interruption may be effected by dilution or by neutralization of the catalyst.  The catalyst is preferably caustic soda in an amount of 3-7 per cent based on the weight of materials other than water in the reaction mixture.  Examples describe the preparation of condensates from formaldehyde and phenol, m- or p-cresol, or o-chlorophenol in presence of caustic soda, and the addition of solutions or emulsions of the partly-neutralized condensates formed with gum arabic and gum tragacanth to paper pulp, e.g. wood pulp, or paper web.
