Title: Detergents
IPC: C11D1/29
Filed: 1951-12-05
Abstract: A detergent composition comprises (1) a water-soluble alkyl benzene sulphonate containing at least one alkyl group with 9-18 carbon atoms, and (2) a water-soluble monoalkyl ether of an alkylene glycol or polyalkylene glycol monosulphate, whose alkyl radical contains 10-22 carbon atoms and whose alkylene radical contains 2-4 carbon atoms.  The monoalkyl ether sulphate may be derived from ethylene glycol, diethylene glycol or triethylene glycol, and may be made by adding ethylene oxide to fatty alcohols such as lauryl, myristyl, cetyl, stearyl and oleyl alcohols, the "oxo" alcohols or alcohols obtained by hydrogenation of fatty acids derived from paraffin hydrocarbons, and sulphating and neutralizing the products.  The proportion of the two components may be in the ratio of 1 part by weight of the alkyl benzene sulphonate to 0.2 to 5 parts by weight of the alkylether glycol monosulphate.  Other substances which may be included in the compositions include meta-, poly- and pyro-phosphates, orthophosphates, silicates, carbonates, sulphates, carboxymethyl cellulose, solvents such as alcohols, hydrocarbons chlorohydrocarbons, monoaryl ethers of polyvalent aliphatic alcohols, or pyridine bases, and preserving, disinfecting and tanning agents. Examples are given. Specifications 343,901, 443,487, 443,559 and 584,439 are referred to.

Title: Apparatus for installing equipment in, and retrieving equipment from, underwater wells
IPC: E21B33/043
Filed: 1961-08-08
Abstract: 950,495. Wells &c. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. Aug. 8, 1961 [Aug. 10, 1960], No. 28665/61. Heading E1F. Apparatus for installing or retrieving, from a base positioned above a body of water, wellhead equipment in a well having a submerged casing- head comprises a pipe string supported by the base and capable of extending to the casing- head, an hydraulically actuated connector carried by the lower end of the string, outwardly extensible latches carried by the connector and engagable with the wellhead equipment, and means in the connector to operate the latches. A casing hangar 41 connected to casing 40 is engaged by the latches 70 of the connector 42 at the base and the casing is lowered by the pipe string 23 until the hanger seats in the casing-head 28. Before latching the connector to the hangar spring loaded slips 50 on the hangar are held inoperative by screws 63, but after latching the screws are removed since the slips are held by pins 64. The latches are engaged with the hangar by supplying fluid through a check valve 96 to move a cam piston 73, and immediately before lowering a needle valve 94 is opened. After the hangar has seated in the head a dart 83 is seated on a shoulder 82 in the connector, and fluid pumped down the string enters a duct 86 to force the piston upwardly. Tension applied to the string frees the latches so that the connector may be raised to the base. The removal of the connector from the hangar permits the pins to move and release the slips which become operative to prevent the hangar and casing moving upwardly relative to the head. When the connector is used to retrieve the hangar or other equipment the valve 94 is closed before lowering the connector into the equipment. A dart 105 (Fig. 8) is seated on the shoulder 82 and fluid pumped down the string passed down duct 107, through part 93, and ducts 92, 91, 90 to force the piston downwardly to engage the latches with the equipment and permit its retrieval. In a modification the valve 94 is replaced by a check valve having   a spring loaded ball and a stem which locks the ball whilst the piston is forced downwardly to engage the latches with the hangar. In a further modification, useful for cementing, the valve 94 is replaced by a check valve having a spring loaded ball closing a passage leading from the space above the piston to outside of the connector, the spring being strong enough to keep the passage closed whilst the piston is forced downwardly and to withstand the cementing pressure. Specifications 948,322 and 950,496 are referred to.

Title: Improvements relating to welding apparatus
Inventor: AMIOT FELIX
IPC: B23K9/02
Filed: 1964-07-13
Abstract: 1,010,036. Welding by fusion. COMMISSARIAT A L'ENERGIE ATOMIQUE. July 13, 1964 [July 12, 1963], No. 28862/64. Heading B3R. In a machine for automatically welding a seam consisting of arcs and straights in a single plane, the work is held with the seam vertical in a cradle which is mounted on a frame movable along a track and is passed under a fixed welding head the frame being traversed when the straights are being welded and the cradle being pivoted about an appropriate axis on the stationary frame when an arc is being welded. A branched pipe in the form of two halves to be welded is held in the cradle 6 carrying guides 10 which locate a pair of chains 11 on paths conforming to the shape of the seam. Initially the frame 7 is traversed by a driving device 13 pulling the chains 11 at constant speed so that the first straight a of the seam is moved under an argon shielded welding torch 5 between which and the work a consumable wire is fed. When a detent 21 engages a first notch 23 in the frame 7, the frame is stopped and the chains 11 turn the cradle 6 about a pivot pin A with the assistance of counterweight 17 while an arc b is welded. At the end of this movement pegs 14 on the cradle 6 engage in recesses in members 15 on the frame 7 and are retained by spring-loaded catches. The frame 7 is again traversed to weld the straight c at the end of which the pin A is ejected automatically and the first guides 10 are removed. The detent 21 engages the second notch 23 and the cradle 6 rotates about the axis B of the members 15 with the aid of counterweight 19 while the arc d is welded. At the end of its rotary movement the cradle 6 engages stops on the frame 7 and the continuing pull on the chains 11 traverses the frame 7 to complete the weld. The work edges are clamped between water-cooled members 27 and a strip supported against the underside of the seam.

Title: Device for measurement of individual ray dose and ray dose rate and for identification
IPC: G01T1/08
Filed: 1954-10-08
Abstract: 811,492. Radiation dose-meters. KERR & CO. (MANCHESTER) Ltd., J. (Total Komm-Ges Foerstner & Co.). Jan. 9, 1956 [Oct. 8, 1954], No. 28983/54. Class 98(1) In a radiation dose-meter consisting of an identification tag combined with a holder for at least one recorder of the amount of incident radiation and means on the holder which enable details thereon in respect of the person concerned to be transferred to part of each recorder which registers radiation received in a given period, a recorder for registering radiation received cumulatively being also preferably provided, the holder(s) are capable of being removed, cut or broken off from the identification, tag along a given line and the recorder(s) are capable of being marked, as by perforations to be identifiable with the holder (and hence the bearer). As shown in Figs. 2, 3, the holder 1 is made of sheet steel and may be broken along the line of slots 2. A plastic cover 3 has turned-over edges 4 engaging the holder 1, and a dosemeter 6, consisting of a piece of photographic film and protected by a foil 6a, is placed between the cover 3 and the holder 1. The cover 3 is fastened to the holder 1 by a rivet 5. The upper part of the holder bears identification data and similar data are reproduced in a form of code perforations on its lower part. The perforations allow film 6 to be pierced by a pin to convey the coded data from holder to the film. A reduced reproduction 10 of the personal register card of the bearer is mounted at the back of the holder and is covered by a convex lens 11. In an alternative form the holder carries a sheet of phosphorus glass which indicates the total radiation to which the holder has been exposed as well as two removable dose-meters which may be partially covered by strips of metal, e.g. lead foil, which in another form may be separated from the film by plastic spacers. When several dose-meters are used, they may have different markings or colours. Each cover and each film has a cut-off corner, to ensure that the films are inserted right way round. The perforations may be filled with a radiopaque substance, which may be coloured to make it easy to see where it has been pierced. Alternatively the holder may, at certain points, be made of, or have recesses filled with, material differing in transparency to radiation from the main part of the holder; or the holder may have teeth or points to transfer the data to the film when pressure is applied. When several films are used, they may be separated as by distance pieces and metal (e.g. lead or aluminium) foil interposed to reduce the effects of secondary electron emission. Filters or fluorescent layers may be provided preferably partially covering the dosemeters, to enable an estimate of the quality of radiation received to be made. Alternatively, the dose-meter films may be of varying sensitivity to varying radiations.

Title: Drive apparatus for example for a windscreen wiper
IPC: F15B21/02
Filed: 1973-06-19
Abstract: 1403347 Fluid-pressure operated motors KNORR-BREMSE GmbH 19 June 1973 [19 June 1972] 29135/73 Headings FIM, F1S A double-acting fluid-pressure operated motor, for example, for driving a windscreen wiper, comprises a fluid-pressure operated reversing valve 4 and a switching control means 17 having a resiliently biased control piston 18 with first and second opposite piston faces, the switching control means having an operating condition in which the first piston face 20 is subjected to the action of pressurized fluid from a control line 16 of the motor and in which the control line 16 is connected also to pass the pressurized fluid to the second piston face 19 through one-way throttle means 28, 29 so that a predetermined pressure change in the control line will bring about a change in the position of the control piston thereby bringing about switching over of the reversing valve 4 and consequent reversal of the movement of a motor driving member (double piston 2) only after a period of delay due to the throttling action of the one-way throttle means. As shown the control piston is associated with a valve-member 22 and this valve-member when moved from its seat enables air to escape out of the chamber bounded by the piston face 20 into the outlet chamber 25 and from there into the connecting line 15 and the line 13. On account of the pressure reduction that accordingly takes place in the chamber bounded by the piston face 20 of the piston 18 the latter is rapidly displaced against the action of the spring 24. Thus via the connecting line 15 and the line 13 the reversing valve is subjected to the action of the compressed air at that control part of the reversing valve to which the line 13 is connected. The valve 4 is therefore switched from the position shown to its opposite position. The double piston 2 is then moved from the extreme right hand position to its extreme left hand position. In a modification (not shown) the control piston 18 instead of being associated with the valve-member 22 acts through the medium of its control rod 21 upon the valvemember of the reversing valve. The operation control valve-member 5 can be switched selectively by means of the control rod 14 into tour conditions i.e. the conditions "block", "park", "continuous operation" and "intermittent operation". In the intermittent operation condition the two portions of the valve that are designated J are in the operative positions. As shown in the figure the two portions of the valve that are designated O are in the operative positions.

Title: Improvements relating to hypodermic injection apparatus
Inventor: JR FAIRLEIGH STANTON DICKINSON
IPC: A61M5/24
Filed: 1950-11-29
Abstract: 698,690. Hypodermic injection apparatus. BECTON DICKINSON & CO. Nov. 29, 1950, No. 29260/50. Class 81 (ii). In order to avoid bursting of the ampoule of a velocity injection apparatus a pressure is applied to the outside of the ampoule, which is approximately equal to the pressure inside. This is achieved by effecting expulsion of the medicament by fluid pressure. In one form the ampoule 16 having a plunger 18 is enclosed in a rubber sac 26, the side walls of which are spaced from the walls of the body 15. Consequently when pressure is applied through the actuating fluid in duct 15<SP>1</SP> it acts upon the side walls of the ampoule at the same time as it thrusts the piston 18 forward. The rubber sac stretches to follow the movement of the piston. Various alternative forms are described in one of which a free portion of the sac is provided to avoid stretching, while in another the ampoule is displaced around a fixed piston during discharge. In another form two separate rubber sacs are provided, one of which surrounds the ampoule while the other serves to apply pressure to the piston and, in a further modification of this the second sac is replaced by a piston and plunger which thrusts directly on the piston in the ampoule. Specification 697,643 is referred to.
