Title: Improvements relating to gas or vapour absorption apparatus
IPC: B01D53/18
Filed: 1943-07-12
Abstract: 569,607. Gas &c. absorption apparatus. INTERNATIONAL FURNACE EQUIPMENT CO., Ltd., and BAILLY, L. July 12, 1943, No. 11287. [Class 55 (ii)] Gas or vapour absorption apparatus comprises a number of superposed troughs a with their undersides, which may be serrated, corrugated or perforated transversely to distribute the gas uniformly, dipping into liquid in the trough beneath. The troughs form a partition in a chamber b, the uppermost being fed with liquid through a pipe f. Staggered outlets e which may be of adjustable height to vary the depth of liquid provide for its descent through the troughs and discharge into a sump g. In a modification, a bank of annular troughs is arranged in a cylindrical chamber with superposed horizontal partitions located alternately within and without the troughs so that the gas flows in zig-zag fashion through the trough series. Heating or cooling pipes may be disposed in the troughs. Specification 1288/05, [Class 55), is referred to.

Abstract: 782,706. Electric selective signalling systems. COLLINS RADIO CO. April 21,1955 [June 23, 1954], No. 11563/55. Class 40 (1). A remote signalling system, which may be used for controlling the position of a shaft in a radio apparatus, comprises a selector unit 10 and coder unit 20 at the control station, a repeater station 40, a decoder 70, and a controlled apparatus 100. The selector 10 drives cams 33, 34, 35, which operate switches 21, 22, 23, so that each of the lines 36, 37, 38 is either grounded or not, eight different sets of conditions being produced. Grounding of the lines 36, 37, or 38 energizes the corresponding relays 53, 54, 55, which operate changeover contacts 41, 42, 43, the movable contacts being connected to corresponding movable contacts, and the upper contacts being connected to corresponding upper contacts, on the cam-operated switches 71, 72, 73, the upper contacts being connected through a relay 86 to one terminal of a battery 88, and the lower contacts being connected via ground to the other terminal of the battery 88. The cams 83, 84, 85, controlling the switches 74, 75, 76, are driven by a motor 92 which is controlled by the relay 86, and also drives the controlled apparatus 100. When the angular position of the cams 33, 34, 35, differs from that of the cams 83, 84, 85, the relay 86 is energized and through contact 91 starts the motor, which runs until the cams are brought into agreement, when its circuit is broken and the apparatus 100 is in the desired position.

Abstract: 567,162. Determining physical qualities of materials. MARCONI INSTRUMENTS, Ltd., and JACKSON, J. July 26, 1943, No. 12137. [Class 37] An electrode assembly for measuring the pH value of a fluid includes a closed electrode chamber e through which fluid to be tested is caused to flow and a second closed chamber g connected to this chamber. The fluid to be tested is led in by a pipe a through a pre-mixer b and one of the ways of a multi-way tap c to the electrode chamber e. Excess fluidflows through a constant-head tube d open to the atmosphere, which governs the rate of flow of fluid through the electrode assembly. Within the chamber e is a glass electrode f, which may have a resistance thermometer in its stem to provide for temperature compensation. At the lower part of the junction of the chambers g, e is a constriction p forming a weir. The reference half-cell or -electrode i is mounted in the side chamber g and the liquid junction is made. through a tube ending in a sintered glass disc h. The chamber g has an outlet tube k .connected by rubber tubing l to a drainage tube m, the height of which is adjustable for regulating the rate of flow of the fluid. A reservoir containing salt-bridge solution, such as saturated potassium chloride, is connected to the half-cell i. A reservoir o containing buffer solution is connected to an inlet of the multi-way tap c. For standardising the tap c is turned to close the inlet tube and empty, the contents of the chambers e, g with the exception of a small quantity which collects in the chamber gas a result of the weir. The tap c is then turned to allow buffer solution to flow - from the reservoir o to fill the electrode chamber e and to immerse the electrode h. After standardisation, the electrode chamber is again emptied and the flow of test solution is recommenced.
