Title: Improvements in and relating to the manufacture of hose pipes
Inventor: KYDD ARTHUR STEVENSON
IPC: B29C35/04
Filed: 1954-08-26
Abstract: <PICT:0780593/III/1> <PICT:0780593/III/2> <PICT:0780593/III/3> <PICT:0780593/III/4> In a method of making a hosepipe of the type comprising a woven jacket 10 and a watertight lining 11 of polyvinyl chloride compounded with an appropriate plasticiser, or a similar synthetic thermoplastic composition, and in the form of a thin tube, the tube is inserted into the jacket and forced tightly against the internal surface of the jacket by a fluid under pressure, and a heating medium is applied to the exterior of the jacket, the heat and pressure combining to cause the tube to adhere intimately with the jacket and set as a permanent flexible lining.  The jacket may be woven seamless and be composed of cotton, flax or the polyester fibre known as "Terylene" (Registered Trade Mark), or either wholly or in part of cotton warps and wefts of "Terylene."  The jacket or the tube, or both, may be coated with adhesive.  Apparatus.  An air heater 20 containing a shallow tunnel 21, the width of which is determined by the number of hose-pipes to be made at the same time, is provided with wheels 22 and runs on rails 23 between two headstocks 25, 26, the headstock 26 being movable along the rails. The fixed headstock 25 incorporates a winch 30, Fig. 4, including a cable drum 32 rotatable in both directions by an electric motor 33 through speed-reduction gearing 34 and change-speed gearing of the reversible and continuously variable type; a further cable drum 35 freely rotatable in bearings 36 is mounted on a fixed support 37.  A cable 31 is led around both drums 32, 35 and attached to the heater so that the latter can be moved in either direction between the headstocks at any selected speed, and for automatically stopping the drive at each end of the range of such movement each headstock is equipped with a limit switch 38 projecting in the path of an associated striker 39 on the heater.  The ends of the hoses are secured between bushes 42, Fig. 6, carried by a cross-bar 43, and tapered plugs 44, the plugs being mounted on the ends of tubes 45 slidably supported and provided with adjustable collars 46 engaged by toggle devices 47 so that the plugs may be forced into the ends of the hoses.  Coupled to each tube 45 is an inlet pipe 50 connected through cocks 51 to a source 53 of compressed air which may be preheated.  In an alternative arrangement, the heater is maintained stationary and the hose pipes moved relatively thereto. Specification 737,216, [Group XXVIII], is referred to.

Abstract: 1,144,088. Cartridge-actuated tools. TORNADO G.m.b.H. 30 May, 1967, No. 24928/67. Heading B4C. A cartridge-actuated tool for driving fasteners, such as nails, 19, comprises a barrel 14 having a cartridge chamber 15 and slidably mounted in a sleeve 13 which is slidable in a casing 1, and a breech member 4 rigidly connected to a mass 8 adapted to assist in absorbing the recoil on firing. The sleeve 13 is provided with a guide member which permits sliding movement of the sleeve and the pivoting of the latter about pins 12 in order to load the tool. The breech member is loaded by a spring 9 and the barrel is held in a forward position by means of a spring-loaded pin 7. In operation, upon pressing the end of the barrel 14 against a workpiece the inner end of the barrel abuts a trigger 5 and so moves the breech member rearwardly against the action of the spring 9. Upon release of the trigger, the breech member moves forward rapidly so that a firing pin 6 strikes the cartridge. The explosive gases may act directly on the nail or via a plunger 18.

Abstract: 334,688. Imperial Chemical Industries, Ltd., Hailwood, A. J., Naunton, W. J. S., Stewart, A., and Shepherdson, A. Aug 15, 1929. Addition to 304,376. Indiarubber, guttapercha, and balata, colouring; dye preparations; lakes.-The pigments used for colouring rubber by the process of the parent Specification are prepared by coating the filler with the vat dye by oxidizing an alkaline solution or suspension of the Leuco compound of the vat dye in the presence of the filler, the latter being treated, before or after the incorporation of the dye, with a soap. The resulting pigments, containing soap, give brighter shades when used in a rubber mix, than those prepared without the use of soap. In an example, a pigment is prepared by boiling magnesium carbonate with soap solution, filtering, suspending the solid residue in a solution of leuco duranthrene brilliant blue R. made by vatting the dyestuff with caustic alkali and hydrosulphite, again filtering and drawing air through the filter cake to complete the oxidation of the leuco compound.

Title: Improvements in and relating to x-ray apparatus
IPC: H01J35/22
Filed: 1939-08-31
Abstract: 532,479. R÷ntgen-ray tubes ; electric supply systems. BRITISH THOMSON-HOUSTON CO., Ltd. Aug. 31, 1939, No. 25011. Convention date, Sept. 1, 1938. [Class 39 (i)] [Also in Group XXXV] In a R÷ntgen-ray tube the discharge takes place in an ionizable medium and through a constriction to enable suitable high potentials to be established in the medium. A mercury pool cathode 12 may be used with keep-alive and starter electrodes 14, 16 ; a cooling coil 13 limits the pressure of the mercury vapour which may be between a fraction of a micron to several microns. A cathode spot anchoring ring 21 of molybdenum surrounds the electrode 16. A thermionic cathode with a neon filling may be used. The constriction is formed by orifices one in each of a number of plates (Fig. 4, not shown) extending across the tube or by an orifice 40 in a thin plate supported by a heavier one 35 sealed to the tube ; a water cooling coil 41 surrounds the plate 35. Shields 52, 53 and 54 surround the anode 29 which carries the tungsten target 30. A cooling system 25, 26 is provided for the anode. The tube is supplied from a source 42 through a resistance 43 and inductance 44 with a condenser 45 and potential limiting spark gap 47 in parallel across the tube. A local circuit 18, 19, 22 is used for the keep-alive electrode 14.

Title: Position control fluid-pressure servo
IPC: F15B21/04
Filed: 1948-09-24
Abstract: 666,776. Fluid-pressure servomotors. BENDIX AVIATION CORPORATION. Sept. 24,1948 [Dec. 26, 1947], No. 25021/48. Class 135. A fluid-pressure servomotor for continuously adjusting a control member, e.g. a valve, in a fluid pressure system to maintain the pressure therein substantially constant, comprises a housing having chambers 34, 20 and 30 separated by an apertured wall 24 and a plate 80 secured in the chamber 30 by a screw - threaded ring 83. The chamber 34 houses an adjustable loading spring 116 whose lower abutment 104 has a stem 106 projecting into the chamber 20 and coacting with a valve member 100 controlling an aperture 90 in the plate 80. Surrounding the stem 106 and sealed to the valve 100 and a bush 96 secured in the chamber 20 by a ring 97 is a regulating bellows 94. The chamber 30 houses a bellows 68 sealed at its upper end to the flange 74 of a rod 78 for positioning the control member and at its lower end to a ring 70 secured in the housing. A compression spring 92 is disposed between the flange 74 and the housing cover 60. Pressure liquid enters the valve chamber 20 through a connection 130 and, after passing through the controlled aperture 90 into the chamber 30, leaves the latter through a throttled connection (not shown). On pressure in the system rising to a value determined by the spring 116, the bellows 94 contracts to raise the valve 100 off its seat to open the aperture 90 a sufficient amount relative to the throttled outlet connection to adjust the pressure in the chamber 30 so that the rod 78 moves the control member to a position to maintain the pressure in the system at its desired value. On the pressure in the system rising above this value, the valve 100 opens further whence pressure in the chamber 30 increases to move the rod 78 outwardly to adjust the control member to decrease the pressure in the system. Conversely, on the pressure in the system falling below the desired value, the rod 78 is moved inwardly due to the decreased pressure in the chamber 30 to adjust the control member to increase the pressure in the system.
