Title: A new or improved safety device for gas taps
Inventor: CHRISTIE ALBERT
IPC: F16L37/107
Filed: 1956-05-01
Abstract: 826,480. Pipe couplings. MESSENGER & SONS (BIRMINGHAM) Ltd. May 1, 1957 [May 1, 1956], No. 13320/56. Class 99(1). [Also in Group XXIX] In a gas tap 10 comprising a body 12 in which is rotatably mounted a valve 16 for controlling the flow of gas from the inlet 14 to the outlet 15 of the tap, the outlet having a bayonettype engagement with a detachable adaptor 11, there is mounted on the body a spring member 39 having a projecting part 41 which is urged into the path of movement of a locking member or portion on the valve to prevent turning thereof. The spring member is cooperative with the adaptor in such a manner that, when the adaptor is engaged with the outlet, the adaptor cooperates with the spring member to withdraw the projecting part of the spring member from the path of movement of the locking member or protion on the valve to permit rotation of the valve. As shown, the body 12 incorporates a rotary, tapered, plug valve 16 provided with lugs 19 between which is pivoted a plate 22 the oppositely disposed keys 23 of which are adapted to drop into slots 24 cut in a rim 25 of the body when the valve is in a closed position, a washer 27 formed with an arm is secured to the valve, that arm being adapted to cooperate with stops to limit angular movement of the valve to 90 degrees. The outlet 15 has an internal, conical seating 38 to receive the part-spherical head 37 of a pipe 31 provided with a shoulder 33 between which and a lip 34 on the adaptor is compressed a spring 32. The adaptor 11 includes pegs 29 which are passed into axial slots 46, 47 in the body, rotation of the adaptor causing one of the pegs to move into the axial extension 48 of a groove 43, and the other peg to engage a U- shaped portion 49 of the spring 39. The latter has oppositely disposed parts 40, 41, the part 40 being anchored in a hole 44, and the part 41 extending between the lugs 19 and being withdrawn by the action of the peg on the portion 49 of the spring to allow the valve to be rotated. When the adaptor 11 is uncoupled, the part 41 returns to a position between the lugs 19, and one of the keys 23 drops into a slot 24 to prevent opening of the valve. When the adaptor is coupled to the tap and the valve is open, the arm of the washer 27 lies in the path of the end 50 of the adaptor and prevents movement inwardly of the latter to the uncoupling position.

Title: Improvements relating to internal combustion driven free piston compressors or motive gas generators
IPC: F02B71/06
Filed: 1938-05-04
Abstract: 502,773. Free - piston compressors. PESCARA; R. P. May 4, 1938, No. 13349. [Class 8 (i)] A multi-stage internal-combustion driven compressor or gas generator has free oppposed synchronized pistons and an even number of stages unsymmetrically disposed, with an equal number at each side of the engine cylinder 1, the compression ratios of the stages being equal, and a pneumatic cushion 6a, 6b of variable pressure on the first stage side acting on a compensating piston connected to the first stage piston, the section of the cushion and mean pressure being arranged so that the force on the compensating piston equals the total pressure resistance. The cushioning space may be used as a starting device, the space 6a being capable of discharge to atmospheric pressure through a valved pipe 16. Starting air is supplied to the chamber 6b from a pipe 28 and through a valve 25 in a piston connected to the valve 21 separating the two chambers; release of pressure through the pipe 29 allows this valve to open, and the starting air to enter chamber 6a and act on the piston. Cushioning air is admitted through a valve 15, the spring of which is controlled by a cam 31 in accordance with the compressor pressure. In a modification, the cushioning space is defined by a piston carried on the compressor piston, the cylinder in which it moves being connected with the outlet conduit by a valve or an aperture controlled by the piston. Specifications 481,595 and 481,666 are referred to.

Title: Means for improving the utilisation in a turbine of exhaust gases from an internal combustion engine
IPC: F02B37/00
Filed: 1931-05-07
Abstract: 372,556. Pumps. SOC. RATEAU, 40, Rue du ColisÚe, Paris. May 7, 1931, No. 13546. Convention date, Dec. 10, 1930. [Class 7 (ii).] In a multi-cylinder engine each cylinder c is provided with an independent exhaust turbine a placed with its intake directly on the exhaust port b of the cylinder, all intermediate piping being eliminated to avoid pressure drop so that the turbine is supplied at a pressure varying during the exhaust stroke. The turbines drive supercharging and scavenging blowers which are each connected with a properly selected cylinder to utilize to the best advantage the varying torque of its driving turbine. The arrangement gives increased turbine power so that the usual separately driven additional series blower for scavenging is reduced in power or may even be dispensed with. Fig. 3 shows a cylinder of a double-acting two-stroke engine the ports e of which are at the middle of the cylinder length. The exhaust turbine a drives a blower f supplying the engine intakes g, g<1>.

The casein solution is made using alkalis or alkaline-reacting salts such as trisodium orthophosphate, borax, caustic soda, ammonia, triethanolamine, butylamine, ethylamine, or amylamine, preferably in excess. Casein may be present in proportions of 1-10 per cent on the weight of oil, and a small proportion of oleic acid may be added. According to examples: (1) A mineral oil solution of phenyl mercuriacetate is emulsified with an aqueous solution of casein and trisodium phosphate.  The mixture is diluted with water for spraying.  (2) A mineral oil solution of phenyl mercurioleate and oleic acid is emulsified as in (1).  Specification 321,396, [Class 81 (i)], is referred to.  The Specification as open to inspection under Sect. 91 is not restricted to the use of an aryl mercury compound but includes any suitable active ingredient such as ethyl mercuri-oleates, p  -hydroxide, -chloride, -acetate, -formate, -phosphate and -nitrate-, or a tetra-alkyl thiuram monosulphide.  In place of mineral oil, a fatty oil, e.g. cottonseed oil, may be used. It refers to the use of the emulsion as dips for timber.  This subject-matter does not appear in the Specification as accepted, but part thereof forms the subject of Specification 426,051.
Patent GB-656902-A (GB)
Title: Paper winding method and apparatus
IPC: B65H19/22
Filed: 1948-05-21
Abstract: 656,902. Winding webs. THOMSON, W. R. May 21, 1948, No. 13849. [Class 100 (i)] A paper-winding machine comprises a frame and a driven winding drum mounted therein, arms pivotally mounted in the frame and having pockets to receive a winding spindle, means for revolving the arms a predetermined distance through an arc, the centre of which lies on an axis laterally offset from the vertical plane through the axis of the drum, the distance between the axis of the pockets and the surface of the drum being at one point substantially equal to the radius of a winding spindle supported in the pockets and gradually decreasing from such point to one end of said predetermined distance and gradually increasing from such position to the other end of said predetermined distance, the axis of the pockets when at said other end of said predetermined distance being offset from said vertical plane in the same direction as the axis of the arc. A winding drum 2 having j journals 2<SP>1</SP> mounted in bearings 3 is driven by a coupling. A stationary eccentric sleeve 9, Fig. 2, secured to each bearing 3 carries on a bush 11 an arm 10 provided with a pocket 12 which supports a winding spindle 14. When the arms 10 are in the upright position the spindle 14 is substantially in contact with the drum 2; counter-clockwise movement of the arms 10 causes the distance between the axis of the pockets and the surface of the drum to decrease, while movement in the opposite direction causes this distance to increase. The arms 10 can be swung on the bush 11 by a gear segment 17 attached to each arm and rotated through gears 18 and 16 by a hand wheel 19 provided with brake means to permit the arms being maintained in positions to which they may be moved. When a roll 35 is substantially complete it is lifted out of bearing members 31 and an air jet 36 is turned on to form a loop 39 in the web 6, and the loop falls into the position 40 indicated when the jet is turned off; a further jet 37 causes the loop 40 to be engaged by the nip of the spindle 14 and the drum 2, the web 6 to be wound on the spindle 14, and consequently the web between the new and completed roll 35 is severed. The arm 10 is moved in a counterclockwise direction as the size of the roll increases, the roll remaining in contact with the drum. The increase in diameter causes the spindle 14 to move radially outwards from the drum 2 out of the pockets 12 and into bearings 31 slidable on rails 30 on arms 29 rotatably mounted on the sleeves 9. The arms 10 are then returned to receive a new spindle 14. The pressure between the roll and winding drum 2 may be maintained constant when the spindle 14 is engaged in the bearings 31 by varying the inclination of the arms 29 through pumps 42 at a rate synchronized with the rate of increase in diameter.
