Patent GB-983869-A (GB)
Title: Control of braking systems and/or tractive systems
Inventor: BROOKS WILLIAM HENRY
IPC: B60T8/48
Filed: 1961-11-22
Abstract: 983,869. Fluid-pressure brake control systems. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. Oct. 16, 1962 [Nov. 22, 1961], No. 41777/61. Heading F2F. [Also in Division G3] When a signal representing the rate of change of peripheral velocity of a wheel of a vehicle exceeds a predetermined value, indicative that the wheel is slipping or sliding, a force, e.g. a fluid-pressure braking force, applied to the wheel is modified until a desired wheel-speed is reached. An A.C. voltage is induced in the coil of a pick-up device associated with a monitored wheel at a frequency directly proportional to the wheel-speed. The output from the pick-up is fed through a squaring and pulse-shaping circuit and discriminator to a differentiator, producing a signal which indicates the rate of change of frequency. A limiter unit provides a signal to a slide corrector unit and a spin corrector unit when the acceleration or deceleration of the wheel is outside permissible limits. As shown, the output from the pick-up is applied at terminal 11 associated with transistor TR1 which clips the positive half-cycles of the applied waveform and provides a signal to a pulse-shaping circuit comprising transistor TR2. The pulse output is applied to a diode pump circuit comprising capacitors C3, C4, so developing a D.C. signal across resistor R12 which is differentiated in circuit R13, C5. The resulting signal is amplified by transistor TR3. A first branch circuit responds to negative signals from the transistor TR3 corresponding to acceleration and comprises transistors TR4, TR5 and TR6. A second branch circuit, comprising transistors TR7, TR8 and TR9 responds to positive signals corresponding to deceleration. When the acceleration exceeds a predetermined value, transistor TR10 energizes relay 14 to initiate sanding operation. If the signal is greater than that which corresponds to this value, transistor TR11 conducts to energize relay 15 for pinch braking. When the signal is still greater, transistor TR12 energizes relay 16 and the traction motors are cut out. Due to the delay provided by capacitors C6, C7, the wheel passes into the decelerating condition and the sign of the signal applied to transistor TR3 changes so that the circuit TR7-TR9 becomes effective to maintain the appropriate correction until the wheel velocity approaches the speed of the vehicle. For correcting slide, transistor TR10 is rendered conductive if the deceleration exceeds a predetermined value whilst transistor TR13 energizes relay 17 for brake reduction at a still higher value. The slide correction is maintained until the wheel begins to accelerate and control of the wheel is taken over by increasing friction with the track and the signal representing rate of change of speed falls within a permissible range of values. Interlocking may be provided by cut-out relays in circuit with transistors TR6, TR9, to ensure that slip correction and slide correction do not occur concurrently.

Abstract: 987,202. Coiling. MORGAN CONSTRUCTION CO. Nov. 8, 1963 [Nov. 13, 1962], No. 44147/63. Heading B3E A machine for forming a number of coils successively in a single location from a succession of non-concentric rings comprises means for continuously feeding the rings substantially horizontally to a position above a collecting table and allowing the rings to drop in the form of a helix to form a coil on the table, means to intercept the fall of the rings to the collecting table while the first coil is removed therefrom and being arranged temporarily to support the oncoming rings whereby when it is removed the accumulated rings fall to the collecting table for the formation of a second coil thereon. Overlapping rod rings 8 are moved along stationary support tracks 10 whilst resting on conveying chain 9 by a driven central toothed chain conveyer 4 to an accelerating tractor 54 comprising a lower endless driven chain unit 60 mounted on a beam 20 and an upper endless chain assembly 58 which is suspended from one end of a pair of levers 36, 38 pivotally mounted on a transverse shaft 24. The opposite ends of the levers are coupled to tension members 44, 46 which are spring biased to counteract some of the weight of the tractor 54 so as to maintain the upper chain in contact with the lower chain to ensure a positive grip on the rings. The linear speed of the chains 58, 60 is greater than that of the conveyer 4. The rings are discharged from the tractor 54 and gravitate down a substantially tubular member 82 over a reciprocable tongue-shaped interior guide means 94 on to a table 80. When the required size of coil has been completed a horizontally disposed flanged intermediate supporting plate 124, actuated by a two-way air cylinder 125, is advanced along guides through the wall of the member 82 to intercept any further rings and prevent them falling on to the coil. Subsequently the tongue 94 is lowered between roller guides 100 by pneumatic means 96 and a motor 106 energized to operate a single revolution crank which advances a pair of vertical plates 118, 119 attached to arms 116 via a lever 114 to push the completed coil on to a conveyer 92. The plates 18, 19 move through slots in the member 82 whilst the coil is pushed therefrom through an opening 90. Finally the tongue is raised and the plate 124 retracted, the piled up rings thereon falling over the tongue to commence a further coil. The leading end of the plate 124 is so shaped at 129, 130 that it will enter between two successive falling continuous helical rings so that a short section of the rod is trapped in the notch 131 thereof and is advanced thereby into the mouth of a shear unit 132, which may run continuously or be started by the rod entering the unit, to sever the ring. A known type of automatic weighing device 127 may be used when coils of a specific weight are required. The machine may be sequence controlled by a series of switches, solenoid operated valves and a time delay unit, Fig. 6 (not shown).

Title: Artificial textile filament having apparent variable denier
IPC: D01D5/32
Filed: 1963-11-12
Abstract: A synthetic thermoplastic polymeric continuous filament of substantially constant denier has a substantially constant cross-sectional area along its length and comprises consecutive segments which are alternately of circular and non-circular (e.g. cruciform cross section.  The segments may be connected to each other by transition regions having asymmetrical cross-sections and the segment connected to one end of each of such a region may have a latent degree of shrinkage under the influence of heat or moisture, differing from that of the segment connected to the other end of the region.  Such yarns are self-crimping and when caused to crimp the crimp developed is random both in kind and in extent and the usual uniform helical crimp does not develop: helical crimp may extend a few inches followed by saw-toothed convolutions that vary randomly in amplitude, period and axial plane.  Alternate segments of the filament consist of a polymer having a high viscosity/surface tension ratio at the meltextrunion temperature, alternating with segments of a second polymer in which this ratio is low.  The polymers may also differ in dye receptivity, being for example low viscosity nylon 6 and high viscosity nylon 66.  Alternatively the polymers may be melt dyed in different colours, giving the resultant yarn a variegated appearance.  The filaments of the invention may be produced by alternate melt extrusion of the polymers through a non-circular (e.g. cruciform) orifice (see Division B5).
