Title: Improvements in or relating to catalytic processes and apparatus for reactions between gases
IPC: C01C1/04
Filed: 1925-07-17
Abstract: 255,232. Synthetic Ammonia & Nitrates, Ltd., and Bramwell, F. H. July 17,1925. Catalytic or contact apparatus; ammonia, catalytic production of from nitrogen and hydrogen.- In effecting catalytic reactions between gases, such as the synthesis of ammonia, the gases are caused to flow downwards through a. single mass of catalyst and then upwards through a tube or tubes embedded therein. Suitable apparatus comprises an outer casing A within which is a catalyst container B fitted with a grid E and a tube D leading to a heat-exchanger F. The gases entering at H leave the heat-exchanger at K and flow downwards through the catalyst, thereafter returning to the heat-exchanger through the tube D and leaving the apparatus at G. The heat-exchanger may consist of two concentric coils surrounding the catalyst container, as described in Specification 241,817, or may be such that a larger number of parallel paths are provided, as described in Specification 248,999. and in the latter case a number of tubes may be embedded in the catalyst corrsponding to the number of paths through the heat-exchanger.

Abstract: 1,041,744. Piezo-resistive devices. ELECTRIC & MUSICAL INDUSTRIES Ltd. May 6, 1963 [May 14, 1962], No. 18409/62. Heading H1K. [Also in Division H4] In one embodiment of a stereophonic pick-up (Fig. la), a V-shaped coupler 3 of resilient material carries V-shaped semi-conductor resistance members 8 and 9 on its arms 4 and 5. The members 4 and 5 are preferably silicon strain gauge members. When a force operates along the longitudinal axis of the arm 4 (or 5) changes in the resistance of member 8 (or 9) are additive.

Title: Improvements in or relating to machines for cutting curves on wooden work-pieces
IPC: B23Q27/00
Filed: 1935-06-28
Abstract: 459,137. Cutting curved surfaces on wood. SCHWAHR, A., 9, Angerstrasse, Leipsic, Germany. June 28, 1935, No. 18621. Convention date, June 28, 1934. [Class 145 (i)] In a machine for generating curved surfaces on wood, the cutter z is mounted on the spindle of a motor u carried on one arm of a two-armed lever i pivoted on a pin h carried by a slide f diametrically adjustable on a rotatable disc b, the other arm of the lever i passing through a pivoted sleeve w. The arrangement forms a slider - crank mechanism, rotation of the disc b by a handwheel c causing the cutter to trace out closed curves such as those shown at 6, 8 in Fig. 3, of which generally only a part is used according to whether a concave or convex surface is to be produced. The form of the curves may be varied by adjustment of the mechanism. In the machine shown, the sleeve w is pivoted to a slide x movable on a guide bar y. Curves of different forms may be produced by alternatively securing the slide x on the bar y and allowing the lever i to slide in the sleeve w, or by securing the lever i in the sleeve w and allowing the slide x to move along the bar y. In the latter case, curves asymmetric about a vertical axis may be produced by securing the bar y, which is pivotally mounted, in an inclined position. The motor u is pivotally mounted on a yoke t adjustable along a slide k carried on the arm i and pivotally adjustable about an axis perpendicular to that of the motor mounting. Further, means (not shown) may be provided for adjusting the motor to bring the cutter above or below the pivotal axis of the lever i, the curves 6, 8 corresponding to two such positions of adjustment. The table 19 which carries the work is traversed perpendicularly to the plane of cut to shape an extended surface on the work.

Abstract: 516,381. Extracting magnesium. MAGNESIUM METAL CORPORATION, Ltd. (American Magnesium Metals Corporation.) June 24, 1938, No. 18764. [Class 82 (i)] In a process for reducing oxide compounds of magnesium with carbon, in which the reaction products on leaving the reduction chamber are cooled and diluted by inert gas such as hydrogen which is circulated after there has been removed therefrom a quantity of carbon monoxide corresponding to the increment due to that formed in the reduction stage, the products from the reduction furnace 1 are sucked by a blower 12 through a condenser 2, cooler 5, and filter 6, part of the gas mixture then passing through a pipe 8 to a holder 10 and the remainder through a pipe 9 to a cooler 14 and one of a series of preliminary cooled adsorption chambers 16, from which the mixture issuing through a pipe 17 is led to the holder 10. By the adjustment of valves 17<1>, 18<1>, the stream of gases is then directed to a second adsorption chamber 16, while the first is evacuated, the first fraction of gas therefrom being returned to the holder 10 and the remainder, containing about 50 per cent. of carbon monoxide, being led to a holder 26 from which, after the conversion of carbon monoxide to carbon dioxide in a plant 30 and the washing out of the carbon dioxide, it is supplied to the condenser 2 through the pipe 3. The plant is started by making water gas in a generator 34 and removing carbon monoxide therefrom in the plant 30. Specification 381,115 is referred to.

Title: Improvements in the manufacture and production of chrome yellow
IPC: C09C1/20
Filed: 1937-07-09
Abstract: Chrome yellow containing lead sulphate, and free from lead molybdate, is prepared by reacting suspensions of lead oxide, lead hydroxide, lead carbonate or basic lead carbonate with solutions of chromium trioxide containing sulphuric acid and free from molybdic acid or a molybdate and from substances tending to dissolve the lead compound used as the starting material.  The lead compound used as starting material may be in a finely dispersed state, and the reaction may be carried out at an elevated temperature.  It is preferable to use a slight excess of the lead compound.  After the reaction is complete, the colour strength and shade of colour of the pigment may be influenced by the addition of a small amount of acid.  Diluents or fillers, such as heavy spar or aluminium hydroxide, may be added to the pigment. Specifications 403,762 and 483,765 are referred to.

Abstract: 320,369. Korselt, J. July 2, 1928. Medicines for internal use; hypodermic injections.-Solutions which are rich in vitamins and can be used for drinking or for hypodermic, injections are obtained by treating the juice of chlorophyll-containing plants, or parts of plants, such as spinach, mangel-wurzel, clover, stinging nettles, or grass, with a sufficient quantity of an acid calcium salt such as acid calcium citrate, lactate, tartrate, or malate to precipitate all the oxalic acid in the juice as oxalate, subsequently heating with the exclusion of air, for example in a neutral atmosphere such as nitrogen, to a temperature not exceeding 100‹ C., and finally sterilizing with the exclusion of air at 100‹ C. By this means chlorophyll and albumen, as well as oxalic acid, are removed from the juice. The acid calcium salt may be prepared by treating calcium carbonate with excess of the appropriate aliphatic oxyacid. According to the Provisional Specification the order of the steps of the process may be varied in any way, and helium may be used as a neutral gas. Reference has been directed by the Comptroller to Specification 193,831.
