Title: Ultrasonic tester
IPC: G01S15/02
Filed: 1966-03-03
Abstract: 1,137,359. Ultrasonic inspection devices. AUTOMATION INDUSTRIES Inc. 3 March, 1966 [16 March, 1965; 4 Jan., 1966], No. 9349/66. Heading H4D. To determine the position of an acoustical target within a workpiece, ultrasonic transducers coupled to the workpiece are energized in at least two modes to provide respective range measurements which are compared. In an embodiment for sensing any displacement of the midline of a brain from the centre of a skull, " right " and " left " probes 24, 26 disposed on either side of the midline 14 are coupled to pulser/receiver units 36, 38. In a first measurement mode, selector gate 48 applies triggering pulses from clock 44 to pulser/ receiver 36 so that " right " probe 24 emits a train of ultrasonic pulses which are received by " left " probe 26 after transmission through the skull. The transmitted and received pulses are applied via " right " and " left " gates 66, 68, signal converter 92 and " through " gate 100 to a cathode-ray tube 22 to provide a display (upper trace) indicating skull width. In a second measurement mode, the transmitted pulses are received by " right " probe 24 after reflection from the brain midline 14 and the transmitted and echo pulses provide a second display (centre trace) indicating the distance of midline 14 from probe 24, " left " gate 68 and " through " gate 100 being closed and a " right " gate 102 being opened in this mode. In a third mode, pulses transmitted and received by " left " probe 26 pass via " left " gates 68 and 104 to tube 22 to provide a third display (lower trace) indicating the distance of midline 14 from " left " probe 26, gates 66, 100, 102 being closed in this mode. If the brain midline coincides with the skull centre, the travel times of ultrasonic pulses reflected from midline 14 or transmitted completely through the skull will be equal; thus any displacement of midline 14 will be evident in the displays by equal and opposite deviations of the " left " and " right " pulse echo times from the " through " transmission time. Displacement of the three traces on tube 22 is effected by the signal converter 92 which superimposes the transmitted and received pulses on three D.C. levels present at outputs 94, 96, 98 respectively, and which also phase-inverts the pulses superimposed on at least one of the levels. The number of ultrasonic pulses in a transmitted train, and the gating of the transmitted and received pulses to tube 22 in the three modes sequentially are controlled by a ring counter or shift register 116 coupled to clock 44 through a frequency-divider 86. The traces on tube 22 may be photographed. In various modifications the amplitude of signals applied to converter 92 may be controlled by an automatic gain control (Fig. 5, not shown), actuated by echo pulses only, the modes may be selected manually instead of in an automatic sequence, and tube 22 may be replaced by a meter.

IPC: B21C47/14
Filed: 1967-02-28
Abstract: 1,170,508. Winding and reeling. GENERAL CABLE CORP. 28 Feb., 1967 [28 Feb., 1966], No. 9373/67. Heading B3E. Wire coiling apparatus includes a capstan on which the wire is wound by a feed roll mounted on a carrier, one of the capstan and the carrier rotating with respect to the other, the said other being capable of turning in response to tension in the wire, under restraint. Wire 24 from a driven capstan 16 passes over guide sheaves 68 and down a hollow rotating shaft 38 to the lower end of which is secured a flyer 40. The wire then passes over rolls 92, 88, 94 and 90 on the flyer 40 to a V- groove in a capstan 70 to lie therein for an arc of 90 degrees, the wire then passing over a roll 98 and under a casting roll 100 on the flyer 40 back into the groove in the capstan 70 to lie therein for an arc of 270 degrees the last 90 degrees of which it lies under the previous 90 degrees lay of wire. The wire then falls in coils on to a receiver 116. The flyer 38, 40 is driven by a pulley 42, variable pulley 46, pulley 60 and pulley 64 on the capstan 16, the variable pulley being so adjusted by screw means 53 that the speed of the shaft 38 exceeds the speed of the capstan 16. The resultant tension in the wire being coiled produces a turning moment on the capstan 70 which rotates slowly in response, being secured to a brake drum 74 engaged by a brake band 78, coils smaller than the capstan 70 thus being produced. The speed of the shaft 38 and flyer 40 can be varied cyclically, to produce a bundle containing cyclically varying coil sizes, by turning the screw 53 by electromechanical means to vary the pitch of the pulley 46. In a modification, Fig. 8 (not shown) the coil receiver may be adjusted eccentrically and be rotated slowly from the braked capstan to produce a patterned bundle. In another modification, Fig. 9, a flyer 340 carries straightening rolls and the coils are directed by an eccentric guide 400, slowly rotated by a braked capstan 370, to a receiver 316. Coil catcher fingers 420 provided on the guide 400 retain a coil temporarily while a full receiver 316 is replaced by an empty one.

[Class 112] Tufting-m a c h - ines.-The foundation fabric of a rug or the like is placed under transverse tension and fed past a bank of-loop-forming needles and loop - retaining. prongs, the prongs entering the material after the needles to retain the loops while the needles are withdrawn to form the next row of loops. The prongs are mounted so as to allow the fabric to be fed while they are in it. The needles and prongs are preferably moved laterally after each stroke so that successive rows of loops are staggered. The needles are preferably of channel form, with the prongs sliding in the channels. In the machine shown, a row of channel-section needles 54 is secured to a bar 49 and a row of prongs 60 is secured to a bar 55, these bars being mounted for longitudinal sliding in vertically movable blocks in standards on opposite sides of the machine. The bars are given independent vertical and longitudinal reciprocating movements by cams on geared shafts 45, 48, the latter being motor-driven, and the movements are timed so that the needles form one row of loops while the loops of the preceding row are held by the prongs, the latter then being withdrawn from the fabric and passed down the channels of the needles to hold the new loops, after which the needles are retracted and the fabric fed with the prongs still in it. The fabric is supported by a grid (not shown) during the operation of the needles. The vertically-movable blocks carrying the bars 49, 55 are provided with inter-engaging vertical teeth with tapered ends to ensure proper register of the prongs and needles after their separate transverse movements. A knife 85 is reciprocated vertically by a cam-actuated lever 90 to cut the loops while they are held by the prongs; the knife is also vibrated longitudinally by a solenoid. Feeding long lengths of fabric.-The fabric F is fed through the machine by chains 25 carrying blocks with pins on to which the fabric is pressed by rotary brushes 32; the chains run in guides and are driven by ratchet mechanism as shown, the lever 41 being actuated from the cam-shaft 45. The fabric is placed under lateral tension in its passage from the roll 20 to the machine by a rotating brush 22 with its bristles arranged helically, the helix being of the opposite hand on opposite sides of the centre line of the machine, and by devices 24 comprising series of rotatable rings with radial pins, the rings lying at an angle to the axis of the device. To give further tension, the chains 25 diverge at the entering end.

Title: Improvements in and relating to devices for the suspension of automatic railway couplings
IPC: B61G5/04
Filed: 1929-03-26
Abstract: 308,805. K³rt÷ssy, L. March 28, 1928, [Convention date]. Coupling, automatic, convertible to non-automatic.-In a railway vehicle having an automatic coupler-head associated with anon-automatic screw coupling, e.g., as during a transition period, the coupler-head 1 is pivotally connected with the usual draw-hook 27 or draw-bar by means of members 29 that transmit tensile forces only, and is maintained in a central position by rod gear 18, which is pivotally connected at one end with the couplerhead and at the other end with the vehicle frame 60 and coacts with one or more centralizing springs 4. In the construction shown the members 29 consist of two links pivoted at their forward ends to pins 33 on the coupler-head and at their rear ends to pins 32 on a link 30 engageable with the draw-hook 27. At their forward ends the links 29 are provided with projections 58 forming faces which abut against the coupler-head in such a way that, in any displacement of the coupler-head, the links 29 and connections 32 can move relatively thereto only in a downward direction. To prevent breakage of the links 29 in case the pins 33 should become clogged, the links are slotted at 59 so that the pins 32 may move therein to give the necessary yielding. The rod gear comprises a pair of supporting rods 18 connected to each other at the rear by a cross-bar 19 to which the springs 4 are attached, and to the underframe 60 by pairs of levers 20, 21, which have unequal lengths so chosen that the forward ends of the rods 18 have an horizontal movement. Pins 11 connected to the, rods 18 by forked projections 61 move in elongated slots in tail-pieces 16 on the couplerhead, these slots being longer than the amount of play of the draw-bar spring, so that the rods 18 are subjected to compressive strains only. Forward movement of the rods 18 is limited by the levers 20 abutting against a projection 53 on a cross-beam 10 of the underframe. When the link 30 has been removed from the draw-hook 27 and the coupler-head 1 swung down, the screw coupling 90 can be passed between the tail-pieces 16 to a position, as shown in Fig. 4, in front of the coupler-head.
