Apparatus for breaking picks in a tyre cord fabric comprises two pains of rolls 104,106 and 108,110 each roll having a plurality of radial flanges interposed with the flanges of the other roll of the respective pair thereof. the rolls of one pair thereof being offset axially from the corresponding rolls of the other pair thereof, whereby each pick of a fabric passed sequentially through the two pairs of rolls will be broken into sections each of a length less than could be achieved by either pair of rolls alone. Axial shifting of the roll 106 is effected by removing a lock nut 118 and engaging a tool with a squared end portion 120 of a stub shaft 114 carrying a bearing 112, extending within the roll 106 and threaded through a fixed bracket 105. The stub shaft at the end of the roll 106 is slidably mounted in a fixed bearing. Each end of the roll 104 is supported by one end of a pair of levers 122 pivoted on a fixed bracket 124 and connected to a piston rod 126 of a cylinder 128 actuatable to move the roll 104 towards or away from the roll 106. A stop 130 limits movement of each lever 122 towards the roll 106. Axial adjustment of the roll 104 is effected similarly to that of the roll 106, i.e. by rotation of a stub shaft 136 which is threaded through the lever 122. A semicircular recess 135 provided with a groove 145 is formed in the bracket 105 to accommodate the edge of the lever 122. The rolls 108, 110 are mounted for axial adjustment and for movement of the roll 108 towards and away from the roll 110 similarly to the rolls 104, 106. The rolls 108, 110 are adjusted axially so as to offset the flanges thereof from the corresponding flanges of the rolls 104, 106 by a distance approximately equal to one half of the spacing of the flanges on any one roll.

Patent GB-430178-A (GB)
Abstract: 430,178. Tipping-apparatus. HYDRAULIC ENGINEERING CO., Ltd., and ELLING- TON, N. B., Charles Street, Chester. Dec. 21, 1933, No. 36034. [Class 78 (iv)] Tipping-apparatus is furnished with anti - breakage delivery means. A troughshaped apron or shoot a, associated or not with an auxiliary shoot k, forms a connecting link between the end door of the wagon and the main delivery shoot l during the tipping process. By operating the bell-crank lever b through the agency of a hydraulic cylinder c or other suitable apparatus, the apron is swung towards the wagon until the stops h contact with the buffers. Up to this point a hydraulic cylinder i acting through a parallel link motion g, with equal or unequal arms, has maintained a cam f in contact with the pin e on the apron to support its forwardend, but when the members g are arrested by the engagement of the stops h with the buffers, the continued movement of the apron releases the member e which then slides down the cam f and allows the front end a<1> of the apron to drop over the buffers before continuing its forward movement until it contacts closely with the end of the truck. Apron and truck then tip as a unit to discharge the contents. During the first part of this movement the cylinder c returns water to the main, but is cut off therefrom after an angle of tip of about 20 degrees. The levers band g are usually duplicated on opposite sides of the apparatus, and the cylinder i may be replaced by a compression spring arranged between the members b, g.

Abstract: 1,240,893. Casting processes; ingot moulds. OLSSON INTERNATIONAL Inc. 11 Sept. 1968 [17 Nov., 1967], No. 43181/68. Heading B3F. Metal slabs and billets are cast in a mould with a cavity defined by a peripheral wall 11 and a bottom wall 19 and provided with a pouring riser 12, by pouring molten metal into the riser and while the cavity is being filled from the riser applying a force to one movable wall (e.g. the bottom wall 19) of the mould to effect a reduction in size of the mould cavity. In Fig. 2, the mould of Fig. 1 is shown in plan and has eight cavities 13 spaced about an octagonal runner 12. The melt is poured from successively higher passages 12a as the mould bases are moved upwardly. The mould is cooled by coolant flowing in passages 21. In an alternative embodiment (Fig. 4) four cavities 34 lead off from a central runner 35 through gates 36. A sheet material (metal sheet or cardboard) 38 covers the gates and is melted or decomposed by the molten metal during pouring. Asbestos pads 40 cover base-plates 39. The peripheral wall parts 31, 32 are clamped by bands 33 bolted to the end parts 32 and wedges 42 between the bands and side-parts 31. A similar construction is used for a single cavity mould with a side riser (not shown).

Abstract: 1406715 Photo-electric store read-out SIEMENS A G 19 Sept 1972 [27 Sept 1971] 43307/72 Heading G1A Information or data stored in a unit 10 is read by projecting light from a laser 1 through it to a detector 12, the beam being split at 5 to form a second beam the light frequency of which is changed and applied to the active surface of the detector together with the information carrying beam to produce by means of the detector an intermediate frequency output signal in the style of a superheterodyne receiver. The detector may comprise a single active area, a plurality of active strips, or several discrete areas. In the single area arrangement the frequency changed beam may be line scanned across the area by a deflector 7. The sub-beam to the detector may be circular or strip like to read-out single areas successively or to read a number of areas simultaneously. The light frequency shift may be achieved in a "modulator" 19 or may be effected in the process of scanning. In the latter case since frequency shift based on the direction of motion occurs, compensation by a controllable modulator may be provided to achieve a constant value of shift. Alternatively the I.F. may be stabilized by an electronic oscillator varied in synchronism with scanning deflection. The amplitude of the light in the main and/or subbeam may be modulated for identification purposes.

Abstract: 923,296. Securing coils for dynamo electric machines. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Dec. 14, 1961 [Dec. 19, 1960], No. 43576/60. Class 35. A method of forming a magnetic structure comprises applying to each of a plurality of elements of magnetic material a first coating of resin which is infusible within a certain temperature range, applying a second coating of resin which is fusible within that temperature range and then applying heat and pressure to mould the structure, the moulding temperature being within the stated temperature range. A magnetic slot wedge, Fig. 1, is formed from a number of iron wires 1 coated with hardened resin, to which another coating of fusible bonding resin 2 is added such that they may be moulded together under heat and pressure without fusing the first coating. The magnetic structure thus has a high proportion of insulated magnetic material to minimize eddy currents. To add mechanical strength to the wedge an outer casing 3 of woven glass cloth treated with epoxy resin is added. The first coating may be polyvinyl resin mixed with phenol aldehyde and heat-treated to produce a film around the element, the bonding resin may be the same mixture but not heattreated to the same extent so that it remains fusible.

Abstract: 1,013,962. Feeding magnetic tapes; sprockets. ETSIURO NAKAMICHI. Nov. 21, 1962 [Nov. 21, 1961; March 10, 1962; March 24, 1962; May 7, 1962; May 21, 1962; July 2, 1962; July 4, 1962], No. 43979/62. Heading G5R. When sprocketed tape, as in Fig. 5, is fed rapidly by a conventional step-motor, the resulting vibrations in the drive may cause triple or worse read-out of a single recorded pulse, Fig. 19. To prevent this: (a) the tape 1 is sandwiched between the sprocket 10 and the head 5, to prevent the tape from fluttering out of head contact, Figs. 7, 8; (b) the head/tape velocity (slope of Fig. 18) is a maximum during read-out for best signal/noise ratio. To locate the tape, as per (a), the sprocket, of capstan type, may incorporate a resilient sleeve 12, Fig. 7, or the tape 1 may itself form the resilient cushion, Fig. 8. In either case, the head 5 is grooved at 5<SP>1</SP> to clear the sprocket teeth. To locate the pulse at the best point, as required by (b), the head may be radially adjusted about the sprocket by eccentric cam means, Fig. 12, or the step-motor 14, and hence the sprocket, may be azimuthally adjusted relative to a stationary head 5 (shown diagrammatically displaced from the sprocket in Fig. 13) by gear means 23, 24. Vibration may be further reduced by making the sprocket of damping material such as polytetrafluoroethylene (Fig. 17, not shown).
Patent GB-439994-A (GB)
Abstract: 439,994. Television. BRAY, T. E., and BAIRD TELEVISION, Ltd., 58, Victoria Street, Westminster. Aug. 24, 1934, No. 24400. [Class 40 (iii)] Relates to a receiver in which a modulated cathode ray beam traverses a line 4, Fig. 1, to record the picture on a continuously moving film which is projected on a screen 18 from an intermittent projector 8. According to the invention, the cathode ray beam is traversed at right angles to the line 4 to an extent necessary to ensure that each picture fills one frame. This traverse is produced by oscillations applied to plates 3 from a relaxation oscillator comprising condenser 15, discharge device 19 and a constant current device 16 which is controlled by the direct current from a cell 9 viewing an edge of the projected picture. Unless the continuously moving film is moving at the correct speed, each frame will include more or less than one complete picture and the line of demarcation between the pictures will be displaced off the edge of the screen. By transmitting the picture with an edge of graduated brightness or of a combination of light and dark lines, the cell 9 may be made to produce the necessary correcting current to traverse the line 4 to the desired extent. The resistance 11 is variable to provide manual adjustment of the potential on the plates 3. The use of one cell 9 only permits correction to be applied if the film runs fast (or slow), but by using two cells, each controlling a separate oscillator and each oscillator moving the cathode ray in opposite directions, correction may be applied if the film runs either fast or slow. In a modification, the sprocket holes are utilized for phasing the picture. The undeveloped film is fed intermittently between a light source 20, Fig. 2, and a cell 9. The transmitted framing impulse is used to extinguish the source 20 so that no light reaches the cell 9 if the picture is correctly phased. If the source 20 is not extinguished when the source, an aperture and the cell are in line, the cell is illuminated and the cathode ray is traversed at right angles to the line 4. The mean speed of the intermittently driven film is equal to the speed of the continously driven film. The use of a fixed aperture of the same size as the sprocket hole between the cell 9 and source 20 is proposed so that the amount of light reaching the cell is proportional to the amount of phasing required. Specifications 269,834 and 320,639, [both in Class 40 (iii)], are referred to.
