Title: Improved process for the production of rubber substances reinforced with threads
Filed: 1930-12-18
Abstract: 365,274. Rubberized fabrics. GUMMIWERKE FULDA AKT.- GES., Fulda, Germany. Dec. 18, 1930, No. 38176. Convention date, Dec. 23, 1929. [Class 140.] A rubberized fabric consisting mainly of warp threads with weft threads at intervals is made by inserting weft threads at intervals into an assembly of warp threads immediately before passing the web through rubber latex or solution, the weft threads being so arranged that each warp thread along the whole of its length is engaged only from the bottom or from the top by the weft threads. The warp threads or cords are drawn from rollers 1, as shown in the Figure, passed through a comb 4, and over bars tc a shuttle device 6 which inserts the weft threads. These may be inserted at any desired intervals, e.g. from 10 to 50 centimetres apart. The weft thread is cut off after each insertion. The warp threads are led over and under the device 6 alternately, in pairs alternate y, or in any other arrangement, and the weft threads are always passed either above or below any one warp thread. The warp threads are kept under tension, so that they are straight and lie in one plane in the finished fabric, while the weft threads are waved. From the device 6 the web passes over a bar 7 and a roller 8, through the bath 14 of rubber latex or solution, and between pressure rollers 11, 12. It then passes to a drying device and is wound up. The drying device consists of a chamber in which the fabric is dried under tension by means of hot air. The fabric obtained may be given a further coating of rubber.

Abstract: 1302588 Roll-forming fodder harvester W R C GEARY 7 Aug 1970 [8 Aug 1969] 38228/ 70 Heading A1F A roll-forming fodder harvester is adapted to move along a windrow of mown fodder, winding it into a roll. The forward part of the machine comprises a vertical rectangular frame constructed of two vertical beams 10 and two transverse beams 12, 14, the frame being carried on ground wheels 16. Hinged at the ends of beam 14 are two parallel beams 30 which carry two separate conical winding elements 44 and are supported on the ground by skids 39. In the first step of operation, jute yarns from spools 87 are threaded, via various pulleys, through holes 90 and attached to the winders 44. The machine is then driven or towed along a row of mown fodder whereupon the contra-rotating pick-up roller 76 lifts the fodder on to the jute yarns which trail behind it. On reaching the winders 44 guided by plates 92, 94 the fodder is wound, while being tied with the yarns, into a cylindrical roll. The arms 30 are forced to rise in a vertical plane to accommodate the roll until it reaches a diameter of from four to seven feet when the machine is stopped and the arms 30 are swung away from each other, freeing the roll. The arms 30 now fall and the machine is driven forwards allowing more yarn to be paid out. The arms 30 are now swung together again whereupon the winders 40 grip, automatically, the yarns. As the machine commences operation again the yarn attached to the first roll is broken and the process repeats when the next roll is complete. The yarn-gripping mechanism, Fig. 5, comprises a finger 50 pivoted near the outer end of each winder. When the winders are separate, the fingers rest on the ground (broken line position) and as the winders come together the fingers pass beneath the fodder and the yarns the latter being arrested by the catches 98. When the ends 56 of the rods 58 finally meet, the plungers 64 act on projections 52 to raise the fingers 50 which trap the fodder and close the yarn catches 98. In a modification of the catch, the yarn is pressed against a resilient pressure pad.

Abstract: 1,270,575. Hydraulic systems; anti-skid control; valves. TELDIX G.m.b.H. 30 July, 1969 [30 July, 1968], No. 38327/69. Headings F2F and F2V. A vehicular hydraulic system includes an electromagnetic valve E in the main pressure line between a master cylinder 3 and a wheel cylinder 4 and in the event of severe deceleration of the wheel during a driver controlled braking action the electromagnetic valve E is actuated to cut off communication between the master cylinder 3 and the wheel cylinder 4 and after a short interval an outlet valve A opens to reduce the pressure in the wheel cylinder 4, the fluid being returned to the line 1 via a line 5 incorporating a pump P and a non-return valve 6. If however the driver ceases operation of the msater cylinder 3 before the valve A opens, pressure will remain in the cylinder 4 and this pressure is relieved through a non- return valve 7 which by-passes the electromagnetic valve E and allows equalization of pressure on either side of the valve E. Fig. 2 shows a practical form of device wherein the valves E and 7 are situated in the same housing held between two clamping plates 8, 9. The valve E comprises a pole member 10 with a magnet winding 11 therearound, the pole member 10 having a central bore 12 for fluid flow which bore 12 has a valve seal 13 engageable by a movable closure member 14. The closure member 14 is fixed to an armature 15 biased by a spring 17. The valve 7 essentially comprises a spring biased closure member 20 movable in a bore 19 and engageable with a valve seat 23. When a braking operation is initiated fluid passes from the master cylinder through the bore 12, the open valve 13, 14 into an annular passage 32 and to the wheel cylinder. On the approach of a skid condition as a result of severe deceleration of the wheel the winding 11 is energized to cause closure of the valve 13, 14. If the pressure in the master cylinder is now reduced before the outlet valve A is opened the closure member 20 is moved off the seat 23 and fluid flows through bores 33, 34 chamber 35, bores 18, 19 and passage 31 to equalize the pressures on opposite sides of the valve E.

Abstract: 954,616. Electric synchronous movements. CREED & CO. Ltd. Oct. 12, 1962 [Oct. 13, 1961], No. 38755/62. Heading H2L. [Also in Division G3] When a positive synchronizing pulse is applied through capacitor C2 and diode D2 to the base of a transistor T2. forming part of a multivibrator T1, T2, transistor T3 is rendered conductive and transistor T4 non-conductive. Brake coil Bk is de-energized and clutch coil Ak is energized, so that motor M drives shaft W2, and perforated disc LS is turned until a photo transistor PT is illuminated from lamp La through one of the holes Lo. Transistor PT then becomes conductive to apply a positive pulse to the base of transistor T1 whereby the clutch is de-energized and the brake is applied. This operation is repeated if further synchronization pulses are applied to the base of the transistor T2, the shaft W2 being moved in steps or continuously rotated according to the frequency of such pulses. In another arrangement, a perforated tape Lst is associated with a drive magnet AM and brake magnet BM. When energized, the magnet AM presses roller R2 and the tape towards roller R1 so completing the drive from motor M to the tape. If the brake magnet is energized, armature Ab presses the tape on to the poles of the magnet. The magnets AM, BM, are controlled in a manner similar to that of the clutch AK and brake BK in the previous embodiment. In further modifications, the brake BK is replaced by means for providing a constant braking force, the transistor T4 being replaced by a resistor, or the brake receives the synchronizing pulses and the clutch provides a constant driving force.

Title: Improvements in or relating to high pressure fluid control valves
IPC: F22G5/12
Filed: 1962-10-17
Abstract: 1,019,715. Valves. A.B. KALLE REGULATORER. Oct. 17, 1962 [Dec. 20, 1961], No. 39313/62. Heading F2V. Communication between an inlet chamber 7 for high-pressure fluid e.g. steam, and a surrounding annular outlet chamber 8 is controlled by a pair of movable closure members 14, 15 on a spindle 13 arranged in chambers 8 and 7 respectively; the spindle also carries a disc 16. The valves are loaded to the closed position by a spring 28 acting through a central lever 27. A channel 32 through the spindle 13 is open at the top and bottom via radial ports 33 and 34, whilst the lower end of the spindle is formed as a needle valve 37 controlling an opening 35 at the end of a water conduit 36. When the valves 14, 15 are slightly open i.e. in a throttling position, the steam impinges on the disc 16 to balance the force of the steam acting on closure member 14; concomitantly an area of negative pressure forms below the disc 16 whereby the water supplied through the ports 34 is distributed in the steam. Upon adjusting the valves to increase the throttling effect the negative pressure below the disc 16 is then sufficient to draw steam from chamber 8 through ports 33 and channel 32 and discharge it from ports 34 whereupon the water is even more finely dispersed in the steam. When the valves 14, 15 are more fully opened the negative pressure below the disc 16 is reduced but the needle valve 37 is retracted to a greater extent and so permits the passage of larger quantities of water.
