Abstract: 1,071,988. Disc brake automatic wear adjustment. D. W. JEFFRIES and H. W. NASH. Nov. 29, 1965, No. 50528/65. Heading F2E. A brake actuating cylinder and piston arrangement having wear adjustment is provided with an auxiliary piston which effects adjustment and with a resilient member to accommodate "knock-back." In the disc brake actuator shown the normal operating range of the piston is defined by the spring ring R<SP>1</SP> and the split ring F<SP>1</SP> embracing the piston 15. The auxiliary piston provided by the 0 ring P<SP>1</SP> experiences the operating pressure and advances the ring on the piston when the operating clearance is insufficient. Excessive clearance is adjusted by the piston slipping through the ring. The spring M accommodates "knock-back" of the piston 15 and returns it to its operating position. In another embodiment (Figs. 1 and 3, not shown) the split ring is embraced by a constriction ring of U section, portions (27) of the base of the U being bowed inwards to engage a recess in the periphery of the ring F. One flange of the constriction ring is deformed and provides the spring ring R<SP>1</SP>. In a second embodiment (Fig. 7, not shown) the split ring (F<SP>11</SP>) engages the cylinder wall and is attached to the piston by a central post (105) to which is attached the auxiliary piston (P<SP>11</SP>). The latter is connected to the piston by a collapsible bellows (103). A spring (M<SP>11</SP>) disposed between the auxiliary piston and the piston face accommodates shock forces on the piston. In a further embodiment (Fig. 8, not shown) the auxiliary piston (F<SP>3</SP>-P<SP>3</SP>) is slidable through a clamp ring 117 to effect adjustment. In a final embodiment (Fig. 9, not shown) the auxiliary piston slides in a cylinder (140) attached to a main cylinder cover (133) and is connected to the slipping ring (F<SP>4</SP>) by way of a central pillar (137).

In operation, compressed air supplied via pipe 20 forces auxiliary piston 7 against bias of spring 8 and the valve moves away from the cylinder. The main piston is then -driven on a working stroke. When supply via pipe 20 is terminated, -the valve 2 closes the cylinder, the space above the main piston is vented via ports 18, 19 and duct 17, and compressed air acting through ports 12, 13 initially forces a piston valve 16 downwardly, and then passes through a nozzle 14. Suction is thus induced in the space above the main piston in the piston valve, which is returned to its initial position. The-piston valve is contacted by the main piston during its-return stroke, and the piston valve closes communication between the nozzle 14 and ports 12, 13. The main piston may be held in its initial position by magnets or as shown by a spring ring 3. The main piston includes a plastics jacket 22 consisting of individual rings 23, 24.

Title: Process for Napping Simulated Fur Fabrics of Acrylic Polymer Composite Fibres
IPC: D06C27/00
Filed: 1966-11-04
Abstract: 1,161,294. Finishing fabrics. JAPAN EXLAN CO. Ltd. 14 Nov., 1966 [13 Nov., 1965], No. 51003/66. Heading D1S. A simulated fur fabric is made by subjecting a pile fabric containing acrylic composite fibres to a temperature of at least 50C in the presence of moisture, applying a light frictional napping motion to the surface of the fabric and drying the treated fabric at a temperature of at least 60C. The expression "acrylic composite fibres" denotes fibres in which two or more acrylic polymers having different thermal properties are eccentrically arranged along the lengths of the fibres. After treatment, three dimensional coil crimps are produced as a consequence of the different thermal properties of the polymers. Suitable acrylic polymers are those of acrylonitrile. with at least one other ethylenically unsaturated monomer copolymerizable therewith, e.g. vinyl acetate, vinyl pyridine, acrylic and methacrylic esters, vinyl chloride, vinylidene chloride, allylsulphonic acid, metharylsulphonic acid and styrenesulphonic acids. Unshrinkable and shrinkable acrylic composite fibres may be used either separately or together. The fabric may additionally contain natural fibres, e.g. wool, regenerated cellulosic fibres or thermoplastic synthetic fibres, e.g. mechanically or two-dimensionally crimped acrylic fibres. In one Example, a tufted fabric comprising acrylic composite fibres prepared as described in Specification No. 1,059,197 blended with regular acrylic fibres, is dyed in a winch dyeing machine and the tufts are raised by a tigering machine and are then shorn two or three times to make them uniform in length. The fabric 1, Fig. 3, is sprayed at 2 with steam or hot water maintained at 50C- 100C to temporarily soften the tulfted acrylic composite fibres. An expander device 3 grips both longitudinal edges of the fabric 1 which then passes onto a moving support 5 which. may be heated and which is provided with stainless steel pins, Fig. 4 (not shown). The surface of the fabric is held in contact with a corrugated hard rubber element 4 which is given either a reciprocating motion or a circular motion to nap the surface. The napped fabric is dried at a temperature of 75C-90C in a rotary drum dryer, Fig. 6 (not shown), with its napped side facing towards the centre of the dryer which is driven at 0.8-1.0 revolutions per second, the direction of rotation being reversed every 10 seconds.

Abstract: 1,206,187. Electromagnetic relays. NIPPON TELEGRAPH & TELEPHONE PUBLIC CORP. and TAMURA ELECTRIC WORKS Ltd. 14 Nov., 1967 [14 Nov., 1966], No. 51766/67. Heading H1N. [Also in Division H4] In a telephone substation (see Division H4) a pair of D.C. relays are arranged so that if one is energized while the other is operated it holds the latter in an operated state. Each relay has its winding in series with a diode to and the two series combinations are connected in parallel in a telephone line so that each relay responds to current in one direction only. If the current reverses in polarity so that operation of relay F is immediately followed by relay M, the relay M operates while relay F is operated as the latter is slow to release. In the operated position of both relays levers 5 and 6 connected to the armatures are displaced to the contact operating positions as shown and two plate members 3 and 4 pivot about their pivot points 1 and 2 respectively under the action of springs 7 and 8. The plate 4 has a tooth D that engages the end of the lever 6 and holds it in the operative position. This position is maintained until both relays are released as a result of replacing the telephone receiver. If a short break in transmission of the current follows a current reversal the relay M does not operate until the relay F has released.

Abstract: 1,163,753. Colour television receivers; phase detectors. RADIO CORPORATION OF AMERICA. 28 Nov., 1966 [7 Dec., 1965], No. 51821/65. Headings H3A and H4F. The invention relates to a colour television receiver for use with P.A.L. type signals which include a colour synchronizing burst which is advanced and retarded in phase by 45 degrees with respect to the - (B-Y) modulation axis in alternate lines, Fig. 1, for the purpose of signalling the phase inversions which are imparted to R-Y modulation axis. In accordance with the invention the phase detector, Fig. 4, in the reference oscillator control loop provides in known manner a first output B<SP>1</SP> from resistor network R1, R2 via low-pass filter C1, C2, R3 for the purpose of providing a D.C. error signal to control the reactance stage for the oscillator and also provides a second unfiltered output A<SP>1</SP> from resistor network R5, R6 which is in the form of a square wave due to the phase changes of the bursts and which serves to control a diode switch, whereby the reference oscillator signal which is applied to the R-Y demodulator is inverted in phase with the inversion of the R-Y modulation axis. Resistor networks R1, R2 and R5, R6 function to isolate the two detector outputs so that the square wave does not interfere with the reactance stage control. Resistors R5 and R6 may be replaced by inductors. An RC or tuned filter operating at 7À8 kc./s. may be included in the square wave output to remove carrier frequency components. In an alternative arrangement, Fig. 3 (not shown), the resistor network R5, R6 is dispensed with and the square wave output is derived from the junction of resistors R1, R2, a high value resistor being inserted between the junction and low-pass filter C1, C2, R3 so as to isolate the square wave and D.C. signal outputs and prevent the filter from attenuating the amplitude of the square wave.
