Abstract: 912,479. Brakes for railway vehicles. DUNLOP RUBBER CO. Ltd. May 19, 1959 [May 27, 1958; Jan. 10, 1959], Nos. 16771/58 and 968/59. Class 103 (1). [Also in Group XXXII] In a brake system for a railway vehicle, a monitor brake 17 is applied to a wheel 2c by actuating a rod 6 which carries a shoe 7 guided in a slot 8 in a lever 10 connected by link 13, bell-crank 11, link 14, an arcuate arm 15 supported on linkage 16, 18, supported on the vehicle frame 1. The lever 10 is pivoted to a lever 23 fulcrumed on the frame and pivoted to one end of the vehicle spring 26 and having a spring 25 arranged between one end and the frame. As the load on the wheel increases, the shoe 7 is adjusted in the slot 8 to increase the pressure on the monitor brake 17. The circumferential reaction on the monitor brake 17 is transmitted through link 20 to actuate the main disc brake 21. The rod 6 may be actuated by a vacuum cylinder 3 or from an hydraulic motor attached to the vehicle side frame. The hinged pressure plates of the main disc brake may be actuated by a double-cam device attached to the rod 20. The circumferential reaction of the monitor brake may operate an hydraulic master cylinder containing two pistons which actuate cylinders attached to the hinged pressure plates of the main disc brake. Fig. 3 shows one form of disc brake in which spokes 32 are attached to the vehicle wheel and a disc 33 is cast in situ about the spokes. Specifications 868,965 and 870,552 are referred to.

Title: Improvements in and relating to apparatus for controlling the supply of water to baths, showers and other lavatory fittings
IPC: E03C1/05
Filed: 1939-06-09
Abstract: 529,877. Photo-electric control of water supply systems. GUMMERS, Ltd., and SHEARD, E. June 9, 1939, No. 16999. Addition to 504,185. [Class 40 (iii)] [Also in Group I] Relates to photo-electric apparatus for opening the supply of water to baths, showers, and other lavatory fittings when a beam of light is crossed by a person as described in the parent Specification. According to the invention, the arrangement is such that inward passage of the person is effective but outward passage ineffective. As shown, a light source 1 projects a main beam 3 across a passage way and the beam is then split by an angular mirror 4 into two separate beams 5, 6 striking separate cells 7, 8 controlling separate relays 12, 13, the relay 12 being normally open and the relay 13 normally closed. These relays are connected in series to a time-switch device 9 a controlling solenoid device 10 to open a water-supply valve 11 for a given time. If a person crosses the beam 3 in the " in " direction, relay 12 closes while relay 13 is still closed, and valve 11 is opened; but if a person crosses the beam 3 in the "out" direction, relay 13 opens before relay 12 can close, and valve 11 remains closed.

Abstract: 126,316. Rudge - Whitworth, Ltd., Pugh, J. V., and Pountney, F. Nov. 29, 1916. Projectile fuses.-Relates to percussion fuses in which a centrifugal flashpassage obturator is provided, and consists in closing the flash-passage. passing through the inertia pellet by means of a member which is movable in a transverse passage in the pellet and is removed by centrifugal force after being freed by the discharge of the projectile. Fig. 1 shows a fuse in which the flash-passage g through the inertia pellet e is closed by a centrifugal pellet-looking rod j, normally retained by a spring-pressed inertia detent k, the rod j being partly located in a transverse passage in the pellet. in Fig. 2, a fuse is shown having an inertia pellet c' and also a firing-pin d' mounted on a cap l which is adapted to be driven in by direct impact. The centrifugal headed rod j<1>, which closes the passage g<1>, is normally held in place in known manner by a tape o. A removable cover r is provided. In two other modifications, a headed rod closing the flash-passage is rendered free to be moved outwards by centrifugal force when the head is broken away from the stem of the rod by inertia on discharge of the projectile. A further modification is shown in Fig. 5, in which the flash-passage-closing member j<4> is wholly contained within the pellet e<4>, itself enclosed by a cage x. When the projectile is discharged, members x<3> supporting the cage collapse, and arms x<2> are enabled to spring out as shown in dotted lines. The rod j<4> then moves outwards and the fuse is thus armed. Specification 126,387 is referred to.
Patent GB-752151-A (GB)
Title: Improvements in or relating to means for detecting the failure of an electric circuit
IPC: G03B27/16
Filed: 1954-06-10
Abstract: 752,151. Lamp failure alarms KODAK, Ltd. June 10, 1954 [June 11, 1953], No. 17109/54. Class 118(2) Means for detecting the failure of an electric circuit including, for example, an electric lamp comprises a transformer having a core which is very readily saturable and having three windings, the first winding being in series with the supervised circuit and normally producing saturation in the core, the second being supplied with current pulses, and the third connected to indicating means responsive to pulses induced from the second winding when the core is no longer saturated due to failure of the circuit of the first winding. A lamp 10 to be supervised is fed from a main supply 11 via transformer 12 and has in its circuit a first winding 13 on a toroidal core 14 which is thereby magnetically saturated. A second winding 26 on the core 14 is fed with current pulses occurring at the peaks of the supply waveform (Fig. 1, not shown) due to rectifiers 29, 30 and "leaky" condensers 31, 32. A third winding 25 is connected to the control grid of a thyratron 35 and bias resister 33. The anode of the thyratron 35 is supplied from the source 11 via a relay 40 controlling an indicator lamp 22. Resister 33 is adjusted so that the negative bias on the grid of thyratron 35 is sufficient to prevent conduction during any part of the anode voltage cycle in the absence of any signal from winding 25. The voltage pulses in winding 25 due to the alternating current in winding 13 occur only as that current passes through its zero point, i.e., when the anode voltage is below striking point. While the circuit of winding 13 is intact the core 14 is saturated and the regular pulses in winding 26 do not therefore induce voltages in winding 25. But if lamp 10 fails the pulses in winding 26 induce voltage pulses in winding 25 occurring at peaks of the supply waveform and the phasing is so arranged that a positive pulse coincides with the positive half-cycle on the thyratron anode. This causes the thyratron to strike, operate relay 40 and signal the failure of lamp 10 by lighting lamp 22. A modification (Fig. 3, not shown) provides for supervision of a plurality of lamps. Each has its own three-winding toroidal transformer, the second windings of all such transformers being supplied in series with pulses from condensers a in Fig. 2 and the third windings being connected in series to the grid of a thyratron which fires as described above should any one of the supervised lamps fail. Alternating current bias may be used for the thyratron instead of using the condenser-rectifier circuit.

Title: Improvements in or relating to electro-magnetic selectors as used in telephone systems
IPC: H01H67/06
Filed: 1932-06-17
Abstract: 395,145. Automatic exchange switches. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and COLLYER, J. E., c/o General Electric Co., Stoke, Coventry. June 17, 1932, No. 17141. [Class 40 (iv).] A ratchet-driven hunting switch is stopped when the appropriate potential is found on the test terminal by the energization of an auxiliary magnet which renders ineffective any further operation of the driving magnet by preventing the driving pawl from engaging the next tooth of the ratchet wheel. The driving magnet, which may be self-interrupting, is subsequently disconnected by a relay in series or in parallel with the auxiliary magnet, or by the latter itself. In Figs. 1 and 2, energization of the auxiliary magnet 15 brings a projection 11 on its armature 13 into the path of a projection 9 on the armature 4 of the driving magnet 2, and so prevents the forward movement of the pawl 8. In Fig. 3, a pin 18 on the armature 13 holds the pawl 8 out of engagement with the ratchet, while in Fig. 4, the armature 13 moves laterally by virtue of springs 20, 21 into engagement with the next tooth of the ratchet so that the pawl 8 is unable to engage the same. Specifications 349,180 and 358,293 are referred to.
