Title: Improvements in hose examining forms
IPC: D06H3/16
Filed: 1955-10-05
Abstract: 801,937. Turning inside out. HALL (TEXTILES), Ltd., B. P., and HALL, W. H. Dec. 21, 1956 [Oct. 5, 1955; June 30, 1956], Nos. 28308/55 and 20321/56. Class 112 [Also in Group VIII] Hose mounted on an examining form comprising a rotatable tube provided with a hose-extending member or members is removed and turned inside out by means of a current of air adapted to carry the hose toe first through the tube. As shown, the form comprises a tube 1, Fig. 3, rotatably mounted in a bracket 2 which forms an air chamber, hose-extending members 3, 4 connected by pin - and - slot connections to the tube, and a piston 11 which is slidably mounted on the air chamber and is connected by pin -and-slot connections to the members 3, 4. The arrangement is such that air pressure may be applied to chamber 2 for moving piston 11 outwardly to extend the members 3, 4, or suction may be applied to chamber 2 for moving the piston inwardly to collapse the members 3, 4. Suction may then be applied to tube 1 for drawing the hose toe first therethrough. Tube 1 is connected by a pipe 14 to a hose-receiving chamber 15. Chamber 2 is connected by a pipe 16 to a valve chamber 17 which is in turn connected by pipes 20 and 23 to the delivery and suction respectively of an air blower 21, and by a pipe 25 to chamber 15. Chamber 17 contains a piston valve connected by a linkage 26, 27 to a pedal 28 suspended from a pivoted shaft 29. When pedal 28 is in its normal or central position chamber 2 is connected to the suction pipe 23, when the pedal is swung to one end-position chamber 2 is connected to the pressure pipe 20, and when the pedal is swung to the other end-position pipe 25 is connected to the suction pipe 23. In a modification, Figs.7 and 9, pipe 14 ends in a cup 31, and a pipe 33, which is pivoted at .one end to pipe 25, is normally biased by a spring 36 against a stop 35 and is provided at its other end with a casing 43 containing a piston 44 formed with longitudinal passages 48. The pedal is also connected by a linkage 37, 38, 39, 40 to pipe 33, and the arrangement is such that when the pedal is operated for applying air pressure to chamber 2, pipe 33 is swung to seat piston 44 in cup 31, a spring-biased catch 46 on casing 43 thereupon engaging a pin 47 carried by cup 31 to hold the piston and cup in contact with each other. When suction is subsequently applied to pipe 33 a hose drawn along pipe 14 obstructs the passages 48, whereby piston 44 moves inwardly against the bias of a spring 50, and a tappet 51 carried by the piston trips catch 46, pipe 33 thereupon being returned by spring 36 against stop 35. Upon cessation of the suction in pipe 33 the hose is deposited on a table top 30.

Title: Improvements in wheel mounting and driving arrangements for vehicles having independently sprung driving wheels
IPC: B60K1/02
Filed: 1934-10-03
Abstract: 445,421. Motor-vehicle axles; mounting motors. TENNANT, W. J., 111, Hatton Garden, London.-(Tatra Works Ltd. Motor & Railway Carriage & Wagon Builders ; 200, Kartouzska, Smichov, Prague) Oct. 3, 1934, No. 28327. [Classes 79 (iii) and 79 (iv)] In vehicles in which the road wheels are driven by separate motors and are mounted on independent part axles swinging about longitudinal axes, the motors are disposed remote from the centre line of the vehicle preferably near the vehicle sides. Space is thus afforded for a low central gang-way in the vehicle. In the construction shown, each road wheel 1 is mounted on an axle casing 4<a> pivoted by lugs 8 to the body 10 so as to swing about an axis Y. An electric motor 7 is carried by the axle casing and drives the road wheel through gearing 6, 5 and 3, 2 which allows the axles to be so spaced that the motors can be placed between them as shown. The gear pinions 3 may be located at the same level as the road wheel axes, or as shown, they may be below these axes so that the whole of the centre line of each swinging axle is below the road wheel axis and the vehicle body may be correspondingly lower. The axle pivots may be situated between the motors and the road wheels as described in Specification 428,017, [Group XXXII], so that the masses on each side of each pivot may be balanced. Specifications 431,921 and 445,442 also are referred to.

Title: Supporting device for use with nipper roll press
IPC: B32B17/10
Filed: 1957-09-09
Abstract: 817,246. Laminating apparatus. PITTSBURGH PLATE GLASS CO. Sept. 9, 1957 [Feb. 11, 1957], No. 28424/57. Class 140. [Also in Group XXX] A nipper roll press for the preliminary pressing of elongated laminated glass panels is combined with an assembly for supporting at least part of the weight of each such panel during passage through the press, said assembly comprising a supporting device having spaced contact pads for substantially non-slip engagement with said panel, cable means arranged at the sides of the press and depending from an upper part of the press to engage said supporting device, and means tensioning said cable means. The supporting device may be pivotally mounted on said cable means. As shown in Fig. 3, support means S is supported by cables 7 which pass upwards, over idling pulleys 8, and carry counterweights 10 on their free ends. The counterweights are together approximately equal to the weight of the supporting device 5 and the laminated panel 4. A similar supporting device S<SP>1</SP> is provided on the exit side of the press. In the inoperative position each device S, S<SP>1</SP> is held down by two inverted hooks 14 on posts 13 one at each side of the device. The panel 4 is placed on the input support S, moved downward to disengage the hooks 14, then towards the nipper rolls 12. The panel then passes through the rolls until they support the bulk of its weight, when the device S is moved away and re-engaged by the hooks 14. As the panel emerges from the other side of the press these operations are repeated in reverse order using the device S<SP>1</SP>. Springs may be used instead of counterweights for tensioning the cables 7. Instead of the pulleys 8 being in a fixed position, as shown, they may be arranged on a horizontally slidable member. Three forms of supporting device are shown in Figs. 1, 9 and 11. In Fig. 1, two wooden arms 1 are fixed to a wooden connecting-bar 2, with a rubber pad 3 at each end of each arm. The arms are so spaced that the pads will engage the panel near its long edges. A metal rod 5 passes centrally through each of the arms 1, being pivotally mounted at each end in lugs 6 secured each to one end of the cable 7. The centre of gravity of the device lies below the rod 7, so that it will remain in equilibrium as shown. Fig. 9 shows a modification in which clamping arms 15 are provided to hold the panel in position on the device. Fig. 11 shows another modification in which the panel is held by suction cups 23 supported on a tubular structure.

Title: Improvements relating to draw-bar connections for tractors
IPC: A01B61/00
Filed: 1936-03-26
Abstract: 472,595. Draw-gear connections for vehicles. McBAIN, W. J. March 26, 1936, No. 28677/35. [Class 103 (v)] A connection between a tractor and a plough or other trailer whereby, on excessive pull on the draw-bar, the tractor is stopped, e.g. by declutching the motor, comprises a spring-loaded member or sleeve 6 subject to the draw-bar load, trip mechanism operated when the pull becomes excessive and a second spring-loaded member 16 controlled by the trip mechanism and arranged to operate the clutch. As shown, the sleeve 6 is rotatably mounted on a rod 8a and is provided with a tooth 5 normally abutting against a projecting lug 4 on a hollow portion 1 of the draw-bar which is slidable in a housing 3. Rotation of the sleeve 6 is obstructed by the engagement of a cammed plate 7 integral with the sleeve with a fixed cam plate 8, and can take place against the effort of a spring 10 only when the selected maximum load is exceeded. When the sleeve 6 is thus rotated a trip lug 11 thereon is moved out of contact with a stop 12 on a pivoted double-arm lever 13, one arm of which bears against the member 16 subject to the pressure of a spring 17, while the other arm is connected to cable or other clutch-operating mechanism 15. Resetting of the mechanism is effected by moving a handle 20 associated with a rotatable sleeve 19, which carries a projecting roller 21 adapted to contact with a finger 22 on the lever 13. Provision is made by means of a nut 8b and a screw 17b, for adjusting respectively the compression of the springs 10, 17.

Title: Improved modulation meter for modulated carrier waves
IPC: G01R29/06
Filed: 1935-10-17
Abstract: 459,563. Wireless signalling. WILLIAMS, F. C., Magdalen College, Oxford. Oct. 17, 1935, No. 28752. [Class 40 (v)] A modulation meter for modulated carrier waves comprises a rectifier with a potentiometer load circuit of appropriate time constant, the voltage at the slider or tapping of which is fed to a second rectifier and to an amplifier, the modulation depth being indicated by the position of the slider or tap which gives a predetermined reading on a current-indicator in the anode circuit of the amplifier. As shown in Fig. 2, the modulated wave in the circuit LC is fed to a diode d1 with its. load resistance r shunted by a condenser x1 which byepasses the carrier frequency and causes voltages to appear across the resistance rl which vary between the peak value and the trough value of the carrier envelope. A fraction of this voltage is tapped off at a slider t and is shunted bv a resistance r3 and condenser c3 of such values that the voltage across the condenser c3 is the mean value of the voltage difference between the slider t and the bus-bar b, the modulation variations being smoothed out by the condenser c3. When the fraction a is equal to the percentage modulation, the voltage at the junction j is just sufficient to start current flowing through a resistance r3 and through the second diode d2. An indication of this current is given by a micro-ammeter m in the anode circuit of the valve A the grid-cathode circuit of which is connected across the resistance r2. Percentage modulation can therefore be read off at the slider t, if this slider is adjusted so that the meter m is just departing from its normal no-input reading. The diode d2 instead of being associated with the diode d1 may form a diode-triode with the amplifier A. In Fig. 5, an arrangement is shown by which modulation may be measured either as a troughto-mean ratio as described above, or as a peak-to-mean ratio. A centre-tap on the resistance r1 is connected to the diode-anode d2, and the condenser c3 associated with the movable tap t is earthed and connected by a switch s to one or other end of the resistance r1. In Fig. 6, the first diode d, is associated with the amplifier A1 in a diode-triode, and the second diode is replaced by grid rectification in the amplifier.

Abstract: 862,729. Two-part couplings. WESTING- HOUSE BRAKE & SIGNAL CO. Ltd. March 26, 1959 [Sept. 8, 1958], No. 28782/58. Class 38 (1). A connector member for use in a plug-in relay mounting base comprises a plate 22 having lugs 25, 26, a barrel 27 for crimping of lead-in wires, and a leaf spring element 28 spot welded to the plate 22. The connector is inserted from the rear face 12 of a moulded base provided with an opening having ramps 16, 17, runners 19 and an entry groove 21. Resilient prongs 29, 30 of the spring element 28 slide along the runners 19, and the lugs 25, 26 snap down into recesses 18 provided at the forward end of the ramps 16, 17. An abutment face 20 prevents the connector being pushed in too far, and to remove the connector, a tool is pushed into the groove 21 to dislodge the lugs 25, 26 upwardly against the action of the prongs 29, 30, thus freeing the connector for withdrawal. A nose 14 guides the appropriate relay contact finger into the opening and transverse location of the finger is assisted by a flat 15. In a modification, Figs. 5, 6, the spring element is dispensed with, the plate 22 being formed of springy metal and having a permanent set 34 which bears against the runners 19. In a further modification, Figs. 7, 9, the edge 48 of a stirrup portion engages the front of an abutment 42 formed in the moulded base, and projections 49 provided on the connector engage rearwardly facing abutments 44. A bifurcated removing tool is insertable down channels 41 formed in the base.

Title: Improvements in or relating to flux responsive magnetic reproducer heads
IPC: G11B5/335
Filed: 1955-10-12
Abstract: 818,811. Magnetic reproducing heads. CLEVITE CORPORATION. Oct. 12, 1955 [Nov. 26, 1954], No. 29059/55. Class 40 (2). In a flux responsive magnetic reproducer head comprising a magnetic core in the form of a substantially closed figure and having an output coil wound around the core and spaced from a reproducing gap in the latter, there are provided excitation means which intersect the core at a location between the gap and coil and within the path of the major portion of signal flux, from a magnetic record medium, within the core. As shown in Fig. 1, the core comprises two legs 11, 12, of either laminated high permeability or electrically non-conductive magnetic material, each carrying respective output coils 15, 16 and joined together at a butt joint 14 and at the reproducing gap 13 which is filled with aluminium or copper foil; the excitation means comprises a single loop of an electrical conductor 19 fed with A.C. or interrupted D.C. of frequency several times that of the highest signal frequency to a reproduced and disposed perpendicularly to the core leg. The joint 14 may be embraced by a conductor 20 fed with D.C. to generate a bias field. In a multichannel head unit a plurality of such heads may be associated with a common excitation and a common bias field conductor, and they may be supported in aligned parallel relationship by a common plastic housing. The excitation means alternatively may comprise a magnetic conductor 47, Fig. 4, in the form of a loop closed through the two legs of a single head or all the legs 40a, 40b, &c. of the plurality of heads and embraced by winding 48 fed with A.C. or interrupted D.C. excitation current. To reproduce signals of very long wavelength the head, Fig. 9, introduces an artificial magnetic potential difference by making the core on opposite sides of the gap 83 magnetically dissimilar; as shown, this is effected by making the pole tips 84, 85 of different size and shape but alternatively the excitation conductor may intersect only one of the core legs. Reference has been directed by the Comptroller to Specifications 709,655, [Group XXXVI], 721,755, 737,497 and 771,383.
