Abstract: 1,181,092. Ultrasonic weld - inspection. WHESSOE Ltd. 3 July, 1968 [3 April, 1967], No. 15163/67. Heading H4D. In a system for welding together the margins of two members, welding electrodes are moved along the margins and the weld is tested at the same time by subjecting it to ultrasonic vibrations a preset distance from the electrodes and analysing vibrations from the weld zone. In the Fig. 2 side elevation support 1 carries three transmitting/receiving piezoelectric transducers P1, P2 (not shown), P3. P1 detects weld defects oriented transversely to the weld line and has its beam axis at 70 degrees to the vertical and 45 degrees to the weld line. P2 detects longitudinal defects and has its beam axis at 70 degrees to the vertical and normal to the weld line. P3 has its beam axis normal to the face of the structure being welded and monitors the acoustic coupling quality. Acoustic coupling of the transducers to the structure is via water retained by skirt 5, or via a silicone grease film. Echo signals received by P1, P2 and P3 are fed via time gates to visual and/or audio warning devices: in the case of P3 the warning device is a lamp which is alight so long as couplant is present. Support 1 is fixed to electric welding apparatus 3 by telescopic arm 2 and is withdrawn from the welded structure by a solenoid if microswitches on support 1 detect the presence of an obstruction.

Title: Method for crimping acrylonitrile polymer fibres
IPC: D02G1/12
Filed: 1958-05-15
Abstract: <PICT:0850126/IV(a)/1> Synthetic fibres or continuous filaments e.g. in tow or bundle form, based upon acrylonitrile polymers are crimped while they are in the aquagel condition, said aquagel containing an amount by weight of water that is at least equal to the quantity of polymer therein, by subjection as by means of a stuffer-box, gear or serrated belt crimper to a compressive force of 50-1000 pounds per square inch of aquagel cross-section for a period not exceeding five seconds and transferring the crimped fibres in unrestrained condition to a heated zone or oven whereby they are dried and simultaneously heat set, also whilst unrestrained i.e. free to shrink.  As shown in Fig. 1, spinning solution (prepared by dissolving one part of the polymer having an average molecular weight between thirty and thirty five thousand in ten parts of a 60% aqueous solution of zinc chloride) is passed from a tank 1, through a conduit 2, forwarded by a pump 3 through a tube 4 and extruded through a spinnerette system 5 into a coagulating liquid 6 (comprising a 43% aqueous solution of zinc chloride) to form aquagel filaments which are then washed in distilled water 11 to reduce the zinc chloride content to 0.05% or less.  The washed tow is stretched to about twelve times its original length by passage between drawing rollers 13 to form a flattened tow or ribbon of 100,000 denier which is fed by driven rolls 16, 17, into a stuffing box 18: after a three second dwell in the box 18, the filaments emerge in crimped condition and pass through a guide 19 to be deposited on a moving belt 20 whereby the filaments are passed, during a period of about ten minutes, through an oven 21 maintained at a temperature between 100 and 150 DEG C.

Title: Improvements in or relating to type printing telegraph apparatus
IPC: H04L17/24
Filed: 1939-05-30
Abstract: 534,206. Type-printing telegraphs. CREED & CO., Ltd., and SALMON, R. D. May 30, 1939, No. 15919. [Class 40 (iii)] In a start-stop printing telegraph receiver of the kind in which a type-wheel is positioned by a rotatable member having a plurality of rows of stops co-operating with detents and placed successively in operative relation with the rows of stops, the detents are moved into their operative positions under the control of signal selecting members and angularly displaced cams, these cams being displaced by different angles so that the intervals between successive cams are in the ratio ¢, “, # &c. On receipt of a start impulse a cam sleeve on a shaft 1, Fig. 1, rotates and a cam 9 through a bell crank 6 causes a longitudinally slidable rod 5 to be aligned in succession with five selector members 7a...e. At the centre of each signal impulse and as the rod 5 is in alignment with each member 7a...e in turn, a five-lobed cam 3 tends to cause a hammer 4 to strike the rod 5 towards the members 7 but actual striking only occurs if by energization of the receiving magnet 13 the hammer 4 is so positioned as to be aligned with the rod 5. Thus each marking impulse causes the appropriate selecting member 7a...e to be tilted, the selected members being held by individual springs. At timed intervals, Fig. 3 (not shown) individual cams 11a...e causes raising of the appropriate members 7a...e and such of these as have been set, by striking one arm 14a...e of three-armed detents 22a...e, cause the setting of these detents to position the typewheel. At the end of a revolution of the cam sleeve, a further cam 11f returns the selecting members 7a...e to their original positions. In a modified construction, Fig. 2, a cam sleeve 32 causes the successive depression of T-members 30a...f into engagement with a common member 33 oscillated by the receiving armature so that these members 30a ... f are set in accordance with the received impulses. The T-members thus set are then raised by the cam sleeve 32 into engagement with the horizontal arms of three-armed detent levers 4b...d, 5b ... d which cause the setting of the type-wheel as in the other described embodiment. In both embodiments, the signal selecting members 7 and 31 have two movements during each cycle, the first being controlled jointly by the received signal impulses and by equallyspaced cam means, the second movement being effected later in the cycle under the control of cams displaced at different angles. Specifications 473,614 and 490,361, and 529,983, [Group XVI], are referred to.

Abstract: 379,730. Coating confectionery. HICKLEY, H. W., 21, Barlby Road, London. June 1, 1931, No. 15960. [Class 28 (i).] The formation of " tails " in the transfer of coated articles from the coating-conveyer to the cooling-conveyer is prevented by arranging a continuously moving surface, i.e. a roller or endless belt, beneath and in contact with the coating conveyer, and in proximity to the terminal roller, the surface moving at a speed greater than the conveyer and in the same direction to move the bottom coating of the centre, or the excess coating, forwardly relative to the centre and counteract the tendency to tail-forming. As shown, the high-speed roller 5, which is driven by a gear wheel engaging a pinion on. the end of the roller shaft, and if desired through a change-speed device, is positioned beneath the wire coating-conveyer 6, and the roller 5 is grooved to accommodate the knuckles in the wire conveyer. The roller 5 is journalled in bearings in the side frames of the machine and an adjustable scraper 10 is supported by straps 12 embracing reduced portions of the bearings. The scraper 10 is notched to correspond with the grooved roller 5. The terminal roller 7 is geared to the wheel driving the pinion on the roller shaft. The roller 5 may be axially reciprocated by a cam on its end engaging a fixed pin. The cooling conveyer passes over an adjustable knife-edge 22. Two or more rollers 5 may be used.

Class 6(i) [Also in Group XXXII] A tractor-mounted hoe comprises a transverse tool-bar 15 carried by a tractor and supporting a transverse shaft 17 upon which are mounted a plurality of pivoted hoe-frames 24 slidable laterally along the shaft and separately spring- urged into operative position. The tool-bar may carry a bracket 13 for attachment to the tractor draught-links 11, 12 or may be mounted between the front and rear wheels of the tractor, Fig. 5 (not shown), on brackets rigid with the tractor chassis. The hoe-frames 24 comprise parallel straps between which the toolstems 26 are clamped. At their front ends the straps embrace a collar 23 mounted in a bracket 19 slidable along the bar but capable of being clamped by a set-screw 22. The bracket includes a depending arm 21, a spring 38 being interposed between the arm and the hoeframe 24 to urge the latter downwardly: the tension of each spring 38 is adjustable by the movement of a spring-anchor member 36 along the hoeframe 24. Struts 44 and 46 are joined to the bracket 13 to form a rigid main-frame which carries a seat 50 and a steering-arm 59 which is connected by track-rods 62 to wheels .56 at each end of the tool-bar, the wheels being carried by cranked forks 55 so that swinging of the arm 59 causes a lateral displacement of the tool-bar. The tools include hoes 29, 30, and discs 31 on cranked axles 34, and are raised out of ground-engagement, when the tool-bar is lifted bodily on the links 11, 12, by a lifting bar 48 suspended beneath all the frames 24 by chains 27. In the construction wherein the tool-bar is rigidly mounted on the chassis, the lifting bar 48 is connected by cables to the power-lift, and raises the frames against the springs 38. In this construction also, the tractor may carry separate .track-eliminating tools, but in the form shown, hoes are mounted behind the wheels 56, which carry scrapers 64. In the underslung arrangement, transporting means are provided comprising wheels mounted on screw-jacks.
