Abstract: 995,678. Welding by pressure. BRITISH WELDING RESEARCH ASSOCIATION. April 20, 1964 [April 22, 1963], No. 15781/63. Heading B3R. In joining two lengths of wire a wire insert is rotated between the ends of the lengths under light contact pressure and after stopping the rotation the pressure is increased to friction weld the insert between the lengths. A length of wire 1 is held in a fixed clamp 2, a length of wire 3 is held in a movable clamp 4 and a wire insert 6 is held between the three jaws of a collet 7 which are held in place by helically slotted sleeves 8, 9 drawn together by bolts 10. The insert is rotated through the sleeves 8, 9 which are driven by rollers 11, 12, 13 and faces of the wire insert and lengths are held under pressure. When the welding temperature is reached the rotation is stopped and a forging pressure is applied. The collet and sleeves are removed from the wire. In a modification the sleeves are tapered and are engaged by tapered rollers. The wires may be of carbon or stainless or rust-resisting steels.

Title: Apparatus for spinning textile fibres, in particular for the purpose of studying thedrafts
IPC: D01H13/32
Filed: 1956-05-24
Abstract: 808,857. Roller drive, draft regulating and recording. SKF KUGELLAGERFABRIKEN G. m. b. H. May 24, 1956 [June 15, 1955], No. 16134/56. Classes 120(2) and 120(3) A test spinning frame for studying drafts has three pairs of rollers and is characterized in that three gears are provided in such a manner that, in relation to a driving motor for the mechanism, the speeds of the delivery rollers, feed rollers and intermediate rollers can be varied by the first gear, the speeds of the feed rollers and intermediate rollers can be varied by the second gear and the speeds of the intermediate rollers only can be varied by the third gear. In the arrangement shown (Fig. 2) motor 2 drives a drum 6 which in turn drives spindles 9 by means of tapes 8. A drive is also taken from the shaft or drum 6 to a variable speed gear 12 which has a direct drive to the front roller 19 and also a drive to a second variable speed gear 13. From the latter a direct drive is taken to the rear roller 17 and another to a third variable speed gear 14 and from there to the middle roller 18. Thus by regulating the variable speed gears 12, 13, 14 by means of handles 23, 31, 39, any variation in the overall draft and the intermediate drafts may be obtained. Means for measuring and recording the uneveness of the roving entering the drafting mechanism and of the yarn leaving it is shown in Fig. 3, and comprises measuring condensers 59, 60, transmitters 61, 62; amplifiers 63, 64; recording heads 65, 66 and magnetic recording tape 67. The recording heads 65, 66 are arranged a distance apart such that the time interval for the tape 67 to pass from one to the other is exactly the same as the time intervals for fibres in the roving to pass from the condenser 59 to condenser 60. In this way the recordings on tape 67 give side-by-side information about the roving and the corresponding yarn produced. Two reproducing heads 68, 69 are provided on the tape and signals from these are passed through amplifiers 63, 64 to measuring instruments 70, 71 and/or curve recorders 72, 73. In a second embodiment the magnetic tape is omitted the signals are used directly on turve recorders. The whole apparatus thus enables the drafting operation to be varied at will and the result of such variation to be studied.

Abstract: 783,468. Centrifugal pumps. BORGWARNER CORPORATION. June 6, 1955 [Nov. 3, 1954], No. 16146/55. Class 110 (1). A pump comprises an impeller having one or more helicoidal vanes extending around a conical hub, the total length of the channel or channels defined by the vane or vanes being greater than any circumference of the impeller, and the cross-sectional area of the channel or channels decreasing continuously from the inlet towards the outlet. Fig. 1 shows a booster pump mounted by means of a flange 14 on the bottom wall of an aircraft fuel tank and driven by an electric motor 13. The impeller is of conical form, with spiral vanes 21, the relative inclination of the impeller hub 25 and the conical housing wall 23 being such that the cross-sectional area of the flow passages 22 between successive vanes 21 decreases from inlet to outlet. The resultant pressure increase condenses vapour contained in the fuel. Fuel enters the pump through a screen 15 and is discharged by way of a volute 18 to an outlet 20. Inlet guide vanes 16 are provided. Instead of being parallel to the plane of rotation of the impeller, the leading edges of the vanes 21 may be at an angle to it. The conical wall 23 may be replaced by a cylindrical wall. The impeller may be hollow so that vapour contained in the fuel can rise through the hollow impeller and escape back to the tank. In a modification, the pump is inverted and mounted below the bottom wall of the tank, with a screened inlet protruding into the tank.

Abstract: 439,292. Knot-tying devices. MELLOR, BROMLEY, & CO., Ltd., BROMLEY, T. C., and HELLIWELL, G. S., St. Saviour's Road East, Leicester. June 1, 1934, Nos. 16392 and 22459. [Class 112] A hand-operated device for tying weavers' knots has yarn receiving guides of unequal length such that the yarn is higher on one side of the bill than the other, the high yarn 9 one side being the low yarn of the other side, so that the yarns are crossed near the bill. In the position prior to use, the pin 11<d> on the quadrant 11 occupies a normal position in a slot 15<c> of the scissor lever 15. The stripper 16 and scissors 13 are below the bill 2<a> and the threads a and b are crossed by placing them in the slots 4, 4<a>. On pressing the thumb lever 10, the bill 2<a> moves in an anticlockwise direction. A pusher 8 and presser 9, Fig. 10, also commence to operate. The presser 9 pushes the thread b down and the pusher 8 pushes the thread a forward. Plates 3<d>, 3<e> hold the threads. The lever 5 between these plates moves to tension the threads. The bill 2a enters between the threads with its jaws open, seizes the rear thread and brings the front thread on to the outside of the bill. The scissors lever. 15 commences to rise and as the tying bill 2<a> turns, the finger 16b on the stripper lever 16 comes up under the thread a on the tying side of the bill and engages the thread a in its notch. At the same time the open scissor device 13 rises and engages the front thread a on the other side of the bill between its blades 13<a>, 13<b>. The bill members close, severing the rear thread b and clamping the front thread a. As the bill 2a continues to rotate, the notched finger 16<b> of the stripper and the scissors move higher, pushing the front thread a upwards, thereby tightening the knot and moving it up the bill. The scissors 13 then sever the thread a and the finger 16<b> completes its rise to pull the knot off the bill. The bill is operated by teeth on the sector 11 engaging teeth (not shown) on the bill shaft 2b. The scissors and stripper are operated by the pin 11<d> moving in the slot 15<c> in the scissors lever 15, a pin 11<e> following the pin 11<d> preventing turning of the lever after the pin 11<d> has left the slot.

Abstract: 796,605. Mercury switches. SUTHERLAND, T. S. May 10, 1956 [Jan. 8, 1955], No. 16419/55. Class 38 (5). A tilting time-delay switch comprises a sealed casing divided by a transverse partition into two chambers, at least one of which contains two electrodes adapted to be bridged by mercury which leaks into the other chamber through a leakage aperture at one end of a tube the other end of which is located in the partition. In one form, Fig. 1, when the cylindrical casing 10 is rotated clockwise through 360 degrees, the mercury 13 is transferred from chamber 15 to chamber 14 to bridge electrodes 18, 19. The mercury then leaks slowly through tube 22 and aperture 23 into chamber 15. In another form, Fig. 2, each chamber has a contact gap between electrodes 181, 191 or 18<SP>2</SP>, 19<SP>2</SP>, and the casing has only to be rotated through 180 degrees to complete a circuit. In a modification of this arrangement, Fig. 3, the casing is of flat pill-box form with the tubes 32, 33 at opposite ends of the partition 28. In each case the electrodes terminate outside the casing in wipe contacts, and are formed from molybdenum or tungsten.

A load-responsive pressurelimiting device, which may also act as a pressure-reducer, for interposition in a compressed air feed pipe to a brake actuator of a pneumatic braking system of a vehicle, comprises a cylinder 10 having a piston 26 which is normally maintained in contact with a cylinder head 40 by a spring 24 interposed between it and a ball-bearing cam follower 20 co-operating with a cam 18, arranged to take up a rotational position in accordance with vehicle load. The arrangement is such that on application of compressed air to an inlet chamber A, and thereby via a valve 34, normally held open by a pushrod 25 engaged by the piston, to a chamber B leading to the brake actuator, pressure is communicated via a restricted orifice 46 from chamber B to chamber C of cylinder 10 to cause the piston to move downwardly when the spring force is overcome so that valve 34 shuts at a pressure determined by the compression of spring 24 by the cam 18, the effect on piston 26 of any subsequent rapid oscillation of the cam 18 being damped by the air in chamber C acting as a cushion owing to its inability to pass quickly through the restriction, so that the device responds only to the mean load. The cam 18 is made load-responsive by mounting cylinder 10 on the vehicle chassis and linking a lever arm 16 secured to the cam shaft 14 to an unsprung member, e.g. an axle of the vehicle. The housing 12 containing the cam shaft and its bearings is filled with lubricating oil via a selflevelling filler plug 48.
