Abstract: 367,365. Looms with stationary weft supplies. BIRD, W. F., of Collins & Aikman Corporation, 51st Street, Philadelphia, U.S.A. Aug. 16, 1930, No. 24608. [Class 142 (ii).] Supplying measured lengths of weft to weft carriers.-Mechanism for drawing out in the form of a loop a length of weft sufficient for two picks comprises a movable yarn gripping and severing member 5, Figs. 4 and 6, which engages the thread extending from a supply 7 and pulls it across the path of a finger 8 provided on an endless chain, a wheel, or the like. After the formation of a loop by the travelling member 8, the member 5 releases the end to permit the leg 9a of the loop to be inserted by the weft carrier 10 and then returns to its initial position adjacent a thread guide 6 where it cuts the second leg 9b and grips the thread connected to the supply prior to repeating the cycle of operations. Alternatively an additional stationary yarn gripping device may be provided adjacent to or formed in combination with the stationary guide 6 for the purpose of engaging the thread after the formation of the loop and preventing extra yarn from being drawn off the supply during the insertion of the leg 9a. In a modification the weft is drawn through a stationary gripping device 13, by one or more gripping and severing members 11 mounted on a chain 12, passed round a stationary hook or finger 14 to form the loop and finally presented to a second stationary gripping member 15 which retains the weft end while the member 11 returns to its initial position. Means may be provided for causing the thread to pass into the path of the weft carrier or into the gripping devices and for adjusting the length of the loop of weft. The mechanism is provided on both sides of the loom.

Title: Improvements in fluid control valves
Inventor: PULLING MICHAEL
IPC: F16K1/46
Filed: 1957-08-02
Abstract: 840,559. Valves. DAMIC CONTROLS Ltd. Sept. 25, 1957 [Aug. 2, 1957], No. 24622/57. Class 135. A charging valve comprises a housing 1 having a member 5 slidable in a bore 4 therein and urged in one direction by a spring 15. The face of the slidable member 5 is provided with an annular recess 9 housing a resilient sealing ring 8. Peripheral flats 14 provide a passage for fluid past the member 5. The housing 1 is screw threaded at 2 at its opposite ends for connection with a source of pressure supply and with the component which is to be supplied with fluid under pressure. On the application of charging fluid the slidable member is forced to the right against the loading of the spring 15 and against the internal fluid pressure of the valve to permit charging fluid to pass through the valve. The valve is designed so that under normal operating conditions the sealing ring 8 makes linear or substantially linear engagement with the seating 7, but should the internal fluid pressure be excessive the face of the slidable member 5 and the seating 7 will abut to limit the compression of the sealing ring 8. The slidable member 5 may be formed in two parts 5 and 5a which when screwed together provide the annular recess 9. The recess 9 is formed so that it is narrower at the mouth than at the base, with the width of the mouth being less than the diameter of the sealing ring. The loading of the spring 15 may be varied by adjusting the sleeve 17.

Title: Apparatus for Evaporating Liquids
Inventor: MATTERN KONRAD
IPC: B01D1/22
Filed: 1968-05-23
Abstract: 1,184,015. Evaporators, film type. METALLGESELLSCHAFT A.G. 23 May, 1968, No. 24741/68. Heading B1B. Liquid is evaporated by passing it through one or more externally-heated tubes the walls of which are impressed with helical indentations of diminishing depth in the direction of liquid-flow, whereby swirling motion is imparted to the liquid and evolved vapour, and the liquid flows over the hot internal walls of the tube(s) in the form of a thin layer. The tube shown, which has three helical indentations, is suitable for an evaporator of the downflow type. The indentations may be pressed from without into a normal cylindrical tube, so that the internal cross-section of the tube gradually increases in the direction of liquid-flow, although the periphery remains constant. The increase in crosssection is preferably so determined that the vapour velocity through the length of the tube is constant. Tubes with helical indentations may be employed in an evaporator of the upflow type, or they may be arranged horizontally, or in an inclined position.

Abstract: 654,317. Road-traffic signals on vehicles. MAGNATEX, Ltd., and RIMMINGTON, F. Sept. 22, 1948, No. 24812. [Class 118 (ii)] In a vehicle direction indicator of the type in which a semaphore arm 3 is actuated by the movement of an armature 2 within a solenoid 1, the coil is surrounded by a magnetic sheathing 13, one end of which is in magnetic contact with a steel collar 8 surrounding the upper end of the solenoid core tube 6. A steel washer or collar 9 is secured to the lower end of the core tube by spinning over a reduced diameter portion 10 and is in magnetic contact with the sheathing. The core tube fits over a magnetic armature stop 16 attached to a support bracket 17, the bracket being made of a magnetic material with a washer 18 of insulating material interposed between the bracket and washer 9 to introduce a small gap in the magnetic circuit between washer 9 and stop 16. Alternatively, the bracket may be made of non-magnetic material. The sheathing is formed of steel tube or rolled sheet, a longitudinal gap or apertures being provided for the coil leads. As a result of these modifications to the magnetic circuit, it is stated that the lines of force passing from the end of the armature as it enters the solenoid are concentrated towards the magnetic sheathing increasing the attraction between the armature and solenoid and reducing considerably the current necessary to operate the indicator. Specifications 635,067 and 637,449 are referred to.

Title: Improvements in apparatus for testing the strength and stretch of fabrics and other materials
IPC: G01N3/16
Filed: 1938-08-25
Abstract: 516,100. Testing strength of fabric, cords, yarns, &c. GOODBRAND, A. N. Aug. 25,1938, No. 24966. [Class 106 (ii)] In an apparatus for testing the tensile strength and stretch of fabrics, cords, yarns &c. of the type in which -the applied load is indicated by the inclination of a weighted pivoted arm, the rate of increase of load to the desired value is maintained constant throughout the test by the provision. of means for varying the rate of traverse of the straining gripper relative to the indicating gripper, to compensate for stretch in the specimen. - Alternatively, the rate of traverse of the straining gripper may be maintained constant at any desired value. In an embodiment, the test specimen is held by two grippers 1 and 2, referred to above as the "indicating gripper" and the "straining gripper" respectively. A downward movement of 'the gripper 1 rotates the pulley 3b and causes 'the attached arm 4,with the weight 5, to traverse a fixed arcuate plate 6. A compensating device, in the form of a second weight 5a fixed to the end of a pivoted rod 5b and in sliding or rolling contact with the weight 5, ensures that the load 'at any instant is proportional to the inclination of the arm 4 to the vertical. The load may be indicated either by a pointer 8 geared to the pulley 3b and moving over a scale 9 or directly on the arcuate plate 6. The gripper 2 is. operated by the rotation of a screwed rod 2a, which is driven by a constant speed motor 19 through the chain 11c, the shaft 11a, the variable speed gear 12, the worm gear 11e and one or other of the change gears 11g, selected by the selector 18. Alternatively, by operation of a two-way clutch 20a, a constant speed drive may be obtained through the worm gear 19a. Any divergence from the desired constant rate of increase of load, caused by stretch in the specimen, is indicated by a difference in the angular velocities of two pointers 14 and 15, rotating over a dial 13. The pointer 14 is driven, by the movement of the gripper 1, through the pulley 3b and a chain 14a while the pointer 15 is driven at a constant speed from the shaft 11a, through a worm gear 11b and timing gears 16. In operation, the variable gear 12 is manipulated so that the pointers 14 and 15 rotate in unison throughout the test.

Title: Improvements in or relating to process of recovering acetylene from gaseous mixtures
IPC: C07C7/11
Filed: 1945-09-28
Abstract: Acetylene is removed from other gases containing it and recovered by a process which comprises scrubbing the gas mixture containing acetylene with a liquid predominantly comprising an ester of phosphoric acid derived from an alcohol containing not more than 6 carbon atoms.  The scrubbing may be done under raised pressure, in which case the acetylene is recovered by separating the gases from the scrubbing liquor and then reducing the pressure to allow the acetylene to escape from the liquor.  Alternatively, the scrubbing may be done at atmospheric pressure and the acetylene recovered from the scrubbing liquor by the action of heat.  Esters mentioned as suitable include trimethyl phosphate, triethyl phosphate, tri-isopropyl phosphate, tri-amyl phosphate and trihexyl phosphate. In examples: (1) cracked hydrocarbon gases containing acetylene are scrubbed with trimethyl phosphate at 50 lbs. pressure.  The solution is separated and the pressure released.  (2) Cracked hydrocarbon gases are bubbled through trimethyl phosphate at atmospheric pressure.  The solution is separated and the solvent heated to 150 DEG  C. to liberate the acetylene.
