Abstract: 1,259,281. Differential steering of vehicles. MARSHALL-FOWLER Ltd. 5 Feb., 1969 [6 Feb., 1968], No. 5901/68. Heading B7H. [Also in Division F2] In a steering system, for an endless track vehicle, having a planetary gear system 5 associated with each track and disposed between a transmission gear and a sprocket drive shaft 2, 3, there is associated with a reaction member 15 of each planetary gear a brake which is applied by the force of a spring 35 transmitted to the brake by hydraulic means controllable directly by the driver of the vehicle. A crownwheel 8 rotates a planet carrier 6 carrying gear pairs 9, of which the gears 9b mesh with gears 14 on the reaction members which are braked for normal vehicle travel, and the gears 9a mesh with gears 11, 12 on the members 15. To turn the vehicle, one of the reaction member brakes is released and if desired a contracting brake 62 may be applied to the respective drive shaft 2 or 3. The reaction member braking means comprises an axially movable disc 16 which is gripped between pairs of pads 17, 19 respectively mounted on a fixed calliper 18 and on a piston 20 mounted in a cylinder 21 in the calliper 18. The cylinder 21 communicates through a pipe 29 with a chamber 27 in a master cylinder 25 containing two coaxial pistons 23, 24 and communicating via check valves 57, 58 with an hydraulic fluid reservoir 56 pressurized by compressed gas in a space 59. To release the brake disc 16 a driver controlled cam 40 is rotated anticlockwise, thereby rotating two bell cranks 42, 47 anticlockwise and drawing down first the piston 23, withdrawing hydraulic fluid from the brake cylinder 21 and then the piston 24 withdrawing fluid from the reservoir 56 through the check valve 57. On rotating the cam 40 clockwise, first the outer piston 24 is raised displacing fluid to the cylinder 21 to move the brake pads 17, 19 into engagement with the disc and then returning fluid to the reservoir 56 against the back pressure of the gas in the chamber 59 and the resistance of the spring- loaded check valve 58. Then the inner piston 23 rises, loaded by the spring 35, closing the valve 54 and the reservoir and displacing fluid to the cylinder 21 to cause the pads 17, 19 to grip the disc 16.

Abstract: 1,266,232. Facsimile transmission system. SOUTHERN PACIFIC TRANSPORTATION CO. 22 May, 1969 [22 May, 1968], No. 26276/69. Heading H4F. In a facsimile bandwidth reduction system in which black and grey copy is scanned the transmitter inverts 20, Fig. 1, the analogue pulse train derived by the scanner 10 whilst preserving the amplitude of the pulses representative of grey marks on the copy, and switch 18 is arranged to select alternate pulses from the inverted and uninverted pulse trains so that in the resulting pulse train 18A alternate pulses are inverted. Although as described alternate pulses of the facsimile signal pulse train are inverted any algorithm for dictating pulse inversion may be employed as long as pulses separated by a zero interval less than two minimum pulse widths long are inverted with respect to each other. As shown the switch 18 is controlled by pulses 24A derived from the facsimile signal by means of a minimum threshold circuit 16, differentiator 22 and clipper 24. The facsimile signal before it is inverted is preferably aperture compensated 12 and clipped in a maximum and minimum clipper 14. At the receiver (Fig. 2, not shown) the received dual-polarity pulse train is restored to a single polarity pulse train whilst preserving the amplitudes of the pulses which are representative of grey marks.

Abstract: 1288934 Rolling metals; continuous casting WEAN UNITED Inc 5 May 1970 [5 May 1969] 22853/69 Headings B3F and B3M A rolling mill stand, which may be associated with a continuous casting plant, is provided with a pair of cantilevered rolls 18, Fig. 2, each of which is driven by meshing gears 23 and 31 carried on the roll shaft and a driving shaft 29 respectively, the roll being carried in a frame 24 which can pivot about the axis of shaft 29. The two rolls can thus be pivoted towards and away from each other in the frames 24 while remaining in driving contact with the shafts 29. A common motor-driven spindle 33 drives wormwheels 32 associated with each shaft. The frames 24, Fig. 3, are urged towards each other at their roll-carrying ends by a cylinder assembly 54. The roll gap is adjusted by a wedge 46 located between the frames, the wedge being operated by a motor driven jack 49. The pressure exerted by the assembly 54 is greater than the rolling pressure normally encountered, but an excess pressure will merely cause the rolls to be safely forced away from one another. The mill stand can be employed in an assembly of four stands, Fig. 1, to roll metal issuing from a multi-strand continuous casting plant. The vertical rolls of the stands are driven by respective motors 15 arranged outside the paths of movement of the metal strands.

Abstract: 1290515 Automatic tension control MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 17 Nov 1969 [20 Nov 1968(2)] 56244/69 Heading G3R Variations in tension of yarn being wound on a spool driven by a three-phase induction motor are detected by vertical movements of a roller operating a differential transformer the rectified output of which is compared with the output of a tachometer generator associated with the motor so that any difference is effective to vary one phase of the supply to the motor to correct the tension. As described, the tension of yarn being wound on a spool driven by a three-phase motor 15, Fig. 2 determines the vertical position of a roller (not shown) which adjusts the position of the core 42 of a differential transformer 12 supplied by a transistor oscillator-amplifier 24, 34. Variations in tension from a desired value produce an output from transformer 12 which is rectified at 13 and added algebraically to the rectified output of a tachometer alternator 18 driven by motor 15. The resultant voltage adjusts, through a transistor 56, the phase of pulses produced by a uni-junction oscillator 55 and applied through a transformer 59 to a bi-directional thyristor 51 or a pair of unidirectional thyristors in series with one phase of the supply to motor 15 so that motor speed is varied and tension restored to the desired value. The supply to transistors 55, 56 is obtained from the three-phase source through a rectifier 52 and a supply from the same source may replace battery 20. In an alternative arrangement, the A. C. terminals of a bridge rectifier are connected in series with one phase of the supply to the motor and a controlled unidirectional thyristor connected across the D.C. terminals of the rectifier.

The cap is radiused at 3, the radius being in the range 0.085 to 0.11 inches. A security band 10 is provided at the bottom of the skirt, and a sealing gasket 4. A tool for applying these closures comprises an outer ring 23, Fig. 5, which engages step 9 of the closure, inside which is a spring member 26 which acts on the radiused parts of the closure top and a member 25 which acts on the top itself. The tool applies downward and inward pressure on the radiused portion of the closure and, when spring 27 is compressed, pressure is applied to step 9. This causes the metal of the closure to be under tension and the gasket 4 to flow to form a seal. The pressure also reforms the step and portion 7 of the skirt into a tapered section, Fig. 4. Whilst the closure is under pressure, screw threads are formed in the closure by rolling, and the security band is secured to the bottle. Specification 974,564 is referred to.

Abstract: 1307725 Sound generator G PASQUALI 20 July 1970 35062/70 Heading G5J A spring M held at both ends by supports S 1 , S 2 , located by resilient guide member G and pads C, is set into longitudinal vibration only by applying a percussion stroke along the directions E 1  or E 2 . The frequency of vibration of the spring may be varied by rotating the support S 2 , thus altering the number of spring coils, and also their diameter. The support S 1  may be Z-shaped, or T-shaped, so that the percussion stroke may be applied at right angles to the spring. The spring may thus be excited indirectly, by displacing the support S 1 , or it may be excited directly by applying a plucking action to the spring by means of a rotatable plectrum, or a rotor body with a discontinuous peripheral surface. The vibrations of the spring may be picked up by permanently magnetizing the spring so there is a magnetic pole at the centre of the spring, and arranging a circular electrical winding around the centre of the spring, spaced from the spring. Alternatively, two springs may be joined by a central support and arranged to vibrate out of phase with each other so that the central support remains stationary, and a winding may be arranged around each spring; the windings being electrically connected in series with each other. The vibrations may alternatively be picked up mechanically, by transmitting the vibrations to a sounding board.
