Patent GB-1250512-A (GB)
IPC: F16K27/04
Filed: 1968-09-19
Abstract: 1,250,512. Valves. TEKTRO Inc. 19 Sept., 1968 [19 Sept., 1967], No. 44603/68. Heading F2V.  A reciprocating spool-type valve, particularly for controlling the supply and exhaust of pressure fluid to and from an actuator such as the jack 40, 42, comprises a valve body 22 having a chamber for the spool with longitudinally spaced inwardly projecting wall portions forming at least three annular valve seats such as the four seats 56, 60, 64, and 62, and a spool-like valve member having at least a pair of collars, such as the three collars 66, 68, 70, provided with corresponding closure surfaces for co-operation with the at least three seats, two of these closure surfaces 60, 64 being provided on one collar 68, such that one of these two closure surfaces along with a third closure surface such as 72 or 62, will seat simultaneously on the corresponding body seats. The valve may be controlled from the supply pressure of an air bottle 30 through a pilot valve 87 as shown. The valve may be pressure balanced by making the outer pair of closure surfaces of smaller diameter than the inner pair, Fig. 8 (not shown). In a double push-button valve, Fig. 4 (not shown), the inner pair of closure surfaces is made smaller so that the valve is held in each operated position by the fluid pressure. Similar effects can be achieved by recessing the inwardly projecting wall portions of the body, Fig. 13 (not shown).  Methods of making.-Either the valve body or the spool, or both, may be moulded in a resiliently deformable plastics material such as polyurethane, neoprene, polyethylene, or rubber, and the spool is assembled by temporarily deforming one or other, or both, of the parts. Thus in Fig. 22, the plastic body 22 has been previously moulded in the material, using either a solid core which has been forcibly extracted or a destructible core otherwise removed. The spool is inserted, by bulging the body between plates 510, with an insertion tool 5081. The original body mould may be left on to form an outer casing (203), Fig. 6 (not shown). A spool 241, Fig. 23, pre-formed by the lost-wax process, has a lapping material 512 adhered to its closure surfaces by a substance 514 which can later be disintegrated and flushed away. Other details and variants.-A main spool and pilot spool valve arrangement may be formed in a one-piece body, Fig. 11 (not shown). The body can include an integral actuating lever with a roller (300, 302) or a solenoid (180) recessed into the body, Figs. 10 and 12 (not shown). Collar parts (105) only of the spool may  be resilient, and grooves (157) may form flexible sealing lips carrying the closure faces, Figs. 8 and 18 (not shown). In a variant, the seats are flat and lands on the spool are grooved axially at (116). An adjustable flow restrictor in the exhaust passages is formed by a thin-walled portion of the body which is deformable by a ball (128) engaged by a screw (132), Figs. 15 and 16 (not shown).

Abstract: 1309637 Damping device for railway bogie vehicles GLOUCESTER RAILWAY CARRIAGE & WAGON CO Ltd 8 May 1970 [13 May 1969] 24388/69 Heading B7L A railway vehicle includes a damping device acting between the superstructure and bogie frictionally restrain relative rotational movement therebetween when the vehicle is travelling in a straight line, the frictional restraint being reduced when the vehicle negotiates a curve. The damping device comprises a block 12 mounted on the superstructure and having a body portion 13 in frictional engagement with a friction liner 14 mounted on the bogie. The portion 13 and liner 14 are biased into engagement by a spring 6, the spring force being applied by a lever 4 connected to a trunnion nut 15 and a T-shaped fulcrum bolt 16 supported in brackets 17 secured to the block 12. As the vehicle negotiates a curve the block 12 is moved by a push-pull rod 18 attached to the bogie and slides over the liner 14, this causes bolt 16 to become inclined to the vertical and with increasing inclination the spring force applied to portion 13 and liner 14, and hence the frictional restraint therebetween, is correspondingly reduced. In an alternative embodiment (Fig. 4) the spring force is transmitted to the block 12 by a cam follower and cam profile formed on the lever and block respectively.  Reference has been directed by the Comptroller to Specification 1,166,652.

Abstract: 1343400 Flame safeguard system for burners NORTH WESTERN GAS BOARD 19 April 1971 [17 Jan 1970] 2374/70 Heading F4T A flame safeguard system for burners comprises means to detect a flame and keep a flame relay FR energized when it is present, means to repeatedly momentarily simulate a flame failure condition of duration too short for the flame relay to fall out and means to respond to voltage changes across the flame relay and establish a fail safe condition if the voltage across the flame relay is above a predetermined value for a predetermined period. The rectifying effect of a flame is used to supply a signal by way of filters consisting of resistors R2, R3 and R4 and capacitors C3, C4 and C5 to a transistor Q1 causing Q1 to be biased off, so allowing a transistor Q2 to conduct and supply current to energize a flame relay FR when a flame is present. A reed relay RR in series with a Zener diode D3 is provided in parallel with flame relay FR to close a reed switch SW to momentarily simultate flame failure when a capacitor C6 has been charged to a sufficient voltage to enable reed realy RR to te activated by the current flowing therethrough. A capacitor C7 is charged through a resistor R7, the time constant being long so that the voltage across C7 lags on that across C6, but a diode D6 is provided to allow rapid discharge of C7 when Q2 no longer conducts. Discharge of capacitors C6 and C7 causes voltage across reed relay RR to drop to open switch SW again so that Q 1 may again be biased off. This cycle of operations is repeated about five times per second and the flame relay FR remains energized throughout and the voltage across FR rises and falls. If a fail to danger condition arises (e.g. transistor Q2 short circuited or transistor Q1 open circuited) the voltage across capacitor C7 continues to rise until a thyristor TH is triggered which shorts transistor Q2 through relay LR causing it to open switch L1, de-energizing the relay and initiating flame failure action. In another embodiment (not shown), relay LR is omitted so that triggering of thyrustor TH shorts Q2 to earth causing it to be destroyed.
