Patent GB-597457-A (GB)
Title: Improvements relating to the laundering of textile materials
IPC: C11D11/00
Filed: 1945-08-20
Abstract: Textile materials are laundered by treating them with an acid positively-charged emulsion of a substantially water-insoluble saponifiable substance so that the substance is deposited upon the textile materials, and subsequently saponifying the emulsified substance on the materials.  The materials may be rinsed with water after treatment with the acid emulsion and before saponification in order to remove, as soluble salts, the insoluble calcium soaps present in the textiles.  The substantivity of the dispersed saponifiable material may be increased by adding aluminium salts. The emulsion may be directly applied as an acid emulsion, or an alkaline or neutral emulsion may be applied and converted to an acid emulsion in contact with the materials. Suitable emulsions are prepared from (1) arachis fatty acids, tallow fatty acids, casein and formic acid; (2) olein, casein and formic acid; (3) mixed fatty acids and skin glue followed by addition of aluminium triformate and formic acid; (4) mixed fatty acids, casein, borax and sodium pentachlorphenate followed by addition of aluminium triformate and formic acid.  In examples (5) and (6), cotton and woollen goods are treated firstly with the acid emulsion, followed by washing and saponifying with soda ash. In example (7), grey cotton cloth is run in open width or rope form through the emulsion of example (3), and after piling down if desired, the cloth is mangled and treated in the keir with a solution of caustic soda under pressure.  In example (8), jute fabric is deoiled on the jig using the alkaline emulsion of example (3), which after 2 or 3 ends is acidified by adding the mixture of aluminium triformate and formic acid, followed by washing and saponification with sodium metasilicate. Specifications 333,177, [Class 15 (ii)], 380,052, 380,065, 380,076, [all in Group III], 394,816 and 421,519, [Group III], are referred to.

Title: Improvements in or relating to continuously-variable variable-speed gearing
IPC: B62M25/00
Filed: 1935-07-29
Abstract: 451,889. Variable - speed ratchet gearing. MANET & CIE, A. G.-C., 18, Avenue Augustin-Dumont, Malakoff, Seine, France. July 29, 1935, No. 21551. Convention date, Aug. 6, 1934. [Class 80 (ii)] An internally-toothed ratchet wheel H is driven at variable speeds by means of pawls F supported on equidistant pivots G, on a rotary hub E which turns upon a fixed eccentric D. As the pawls F sweep round in the space between the hub E and ratchet H, they open out and close in upon one another, and the speed of the driven ratchet H is varied by changing the angular position of a gap W, Fig. 2, in a masking guide M. The guide M is a slot in the face of a disc K which is adjusted angularly by a control cable L, Fig. 1. Each pawl carries a pin f near its outer end, and as long as a pin f is in the slot M the pawl is held clear of the teeth H. When a pin f sweeping clockwise of Fig. 2 reaches a point S<1>, it leaves the masking slot M and passes along outside a floating spring-pressed beam S which fits in the gap W and holds the pawl resiliently against the teeth H. That pawl drives, but only until the drive is taken up by the next pawl following, so that each pawl drives through the distance between the points of the pawls at the place which the gap W has been moved round into. After a pawl F has traversed the gap W, its pin f is picked up and carried on by the masking guide M. In the application to a cycle crank-bracket drive, a pedal R, Fig. 1, engaging a square slot Q drives a concentric disc P which is connected by a ring of drag links N to the pawl hub E which turns on a ball bearing on the eccentric D fixed rigidly to the bracket A. No lock is required for the control end of the cable L.

Patent GB-589392-A (GB)
Title: Mechanical linkage
IPC: G01F15/02
Filed: 1944-11-08
Abstract: 589,392. Linkwork. FOXBORO CO. Nov. 8, 1944, No. 21983. Convention dates, Nov. 22, 1943. [Class 80 (iii)] [Also in Groups II, XIX and XXIX] A linkage for transmitting motion from one member 35, Fig. 3, to a second member 12 in adjustable ratio, comprises a spindle 10 movable about an axis M N and carrying the member 25 and a yoke 17 in which is pivoted a pin 16 rigid with a bell crank lever 15. One end 19 of the latter is connected by a link 11 to the member 12 and the end 18 of the other arm is connected by a link to an adjusting member'movable along or parallel to the axis MN. Movement of the adjusting member thus varies the throw L of the point 19 and hence the scale of movement of the member 12. As shown, applied to a flow meter, a pressure proportional to the flow measurement is transmitted through a pipe 30 to a Bourdon tube 31 connected to the member 35. A pressure corresponding to the static pressure of the flow being measured is led to a Bourdon tube 24 connected to the point 18 of the lever 15. The member 12 is connected to an indicator 22 which thus indicates the flow modified in accordance with the variation of the static pressure. In the position indicative of zero flow, the point of connection 21 of the link 11 and member 12 lies on the axis X Y of the pivot 16 so that angular movement of the lever 15 about the axis XY has no effect upon the indicator 22. In a ratio flow control system the linkage is used to vary the ratio in which one flow is controlled with respect to a second flow. The primary flow acts upon the member 35, Fig. 2, such'as by the use of a Bourdon tube 31, Fig. 3, the point 18 is connected to a lever 27 movable along a scale 42 indicating the ratio setting value, and the link 11 acts on the nozzle of a flapper pilot valve 12<1>, 37 of an on-off controller such as described in U.S.A. Specification 1,582,868, and which is supplied by air through a pipe 41. The flapper 37 is moved by a Bourdon tube in response to the value of the flow contolled. The relative position of the parts 17, 35, may be adjustable, and spring means may be inserted between these parts to take up excessive movement of the member 35. The linkage may be applied to apparatus for the control of fuel to air ratio, for the blending of petroleum products, for the introduction of odorant into illuminating gas, or for the introduction of dye into continuously flowing material.

Abstract: 479,851. Starting. HEYWOOD, C. F. Aug. 11, 1936, No. 22097. [Class 7 (v)] A multi-cylinder engine is started by injecting into each cylinder a mixture of fuel and compressed air or a non-inflammable gas, during the compression stroke, in addition to an injection of the air or gas alone, or of the fuel mixture, during the expansion stroke. The compressed air or gas is supplied from a reservoir 15, past a manually-operated valve 16, to an annular chamber 13 behind a rotary distributing valve 18 which is driven by gearing 21, 22 from the cam-shaft, and has ports 19, 19a registering in turn with pipes 7 ... 10 leading to non-return valves 6 in the cylinder heads. The ports 19a are supplied by a passage 19b with the fuel mixture formed by the ejector action of the compressed air or gas flowing past an adjustable nozzle 27 connected to a fuel tank by a pipe 25. The ports 19 extend. through the valve 18 and are fed directly by the compressed air or gas. As soon as the engine fires the valve 16 is closed and the engine will continue to operate on combustible mixture drawn from the normal carburetter 3. In a modification, the annular chamber 13 is supplied with a compressed mixture of fuel and air or gas, the fuel supply and the nozzle 27 are omitted, and the port 19 is elongated to include the port 19a. The fuel mixture will thus be continuously injected during the latter part of the compression stroke and the whole of the expansion stroke. Specification 417,180 is referred to.

Filed: 1927-08-23
Abstract: 276,668. Gewerkschaft der Steinkohlenzeche Mont-Cenis. Aug. 26, 1926, [Convention date]. Hydrogen. - Hydrogen or gases containing hydrogen are purified by treatment first with alkaline substances in dissolved, solid, or fused state for removing carbon dioxide, hydrogen sulphide, sulphur dioxide, &c., and then at an increased pressure and temperature with a catalytic mass containing finely divided metals of the iron group, especially nickel, or containing chromium, manganese, zinc, or vanadium in metallic or oxide form, the gas being then subjected to a second alkaline treatment and again brought at an increased pressure and temperature into contact with a similar catalvtic mass. The catalytic mass may also contain compounds of the alkali, alkaline earth, or earth metals, and may be produced by impregnating carriers having a large surface with the nitrates of the metals which are then decomposed by heating at as low a temperature as possible, hydrogen or a gas containing it being passed over the mass during or after decomposition. For the alkaline purification quicklime, slaked lime, soda lime, potassium line, caustic soda or potash, soda or potash solutions, an aqueous suspension of magnesia, or ammonia in liquid form or in aqueous solution mav be used. The catalytic treatment mav be effected, when a finely divided metal of the iron group is employed, at a temperature between 150‹ and 450‹ C. and at a pressure above 5 atmospheres, preferably 70-800 atmospheres. The catalytic treatment removes carbon monoxide, producing water vapour, which may be removed by a drying agent, and methane. The hydrogen may be obtained from water gas or coke furnaces gases and may be employed in ammonia synthesis or other catalytic processes.
