The tapes 5 are on pulleys 3 and rollers 4 and move continuously over the surface of the table 1. A rear set of front stops 7 on a transverse rockshaft 6 engage grooves 8 in the table, and at the proper time these stops are rocked forward to permit the sheet fed to them to move on with the tapes. Sheet-holders 12 of wire or other light sheet holders are adjustably mounted at their rear ends on transverse shafts 9, 10, and rest by their weight on the sheets or may be spring pressed. A fixed side-lay 13 is provided to which the sheets are fed in conjunction with the stops 7. As the sheets reach the front stops 19 they are registered sideways by the reciprocating side lay or pusher 15.
Patent GB-808575-A (GB)
Title: Improvements in and relating to "on-load" electrical switching arrangements comprising transition impedances
IPC: H01H9/00
Filed: 1956-03-02
Abstract: 808,575. Switching systems; transformer arrangements. SOC. GENERALE DE CONSTRUCTIONS ELECTRIQUES ET MECANIQUES, ALSTHOM. March 2, 1956 [March 4, 1955], No. 6641/56. Class 38 (4). An on-load electrical switching arrangement - in particular one for use with a transformer tap-changing system-in which an impedance is used in the transitional switching operations comprises a time-delay relay protective means, the time delay of the relay being slightly longer than the time rating of the impedance so that the impedance is protected should the switching operations take longer than the normal time. In a transformer tap-changing system two contactors 4, 5 are normally on one tapping, say A, at the same time. Simultaneously a moving contact 13 is bridging contacts 10, 14 in a device 9 and a contact 16 bridges a pair of contacts in the circuit of a time-delay relay 6. Under these conditions an impedance Z1 is short-circuited, the tapped voltage being taken from a terminal 3 and the relay coil 6 is energized to hold a contact 7 open. To change the voltage tapping from A to B, contactor 5 is first moved from tap A to tap B and the contact 13 is moved to bridge contacts 14, 15 thereby opening contact 16 to deenergize the relay coil 6. The tapped voltage from terminal 3 is now supplied over two impedances Z1, Z2 in parallel. Contactor 4 is now moved from tap A to tap B and the contact 13 moves to bridge contacts 15, 11 and to close contact 17 once more energizing the relay coil 6. The tapped voltage is now taken from the terminal 3 irrespectively of the impedance Z2 which is short-circuited and the contact 7 is once more held open. Should, however, the sequence of operations in changing from tap A to tap B take longer than a predetermined time, that is the rated time of the impedances Z1, Z2, the relay coil 6 will be de-energized long enough for the delay time of the relay to be exceeded. Contacts 7 will thus close and operate a protective device to prevent damage to the impedances Z1, Z2. A contact such as 16 will be provided for each tapping, and these may be connected either in parallel or in series, and the contact 7 of the time-delay relay may be arranged to be normally open or normally closed.

Title: Improvements in or relating to brake accelerators for vacuum brakes of rail vehicles
IPC: B60T13/46
Filed: 1962-02-21
Abstract: 939,782. Fluid-pressure brakes. KNORR-BREMSE G.m.b.H. Feb. 21, 1962 [Feb. 28, 1961], No. 6808/62. Class 103 (1). An accelerator for vacuum brakes of rail vehicles provided with a compressed air installation comprises means which under manual or automatic control enable compressed air to be fed from the compressed air installation via the driver's brake valve into the train pipe of the vacuum brake, at least at the start of a braking operation. The invention relates particularly to direct two-chamber vacuum systems wherein a train pipe 9 is connected to the lower chamber of each brake cylinder 7 and is fed from a source of vacuum 3 via a driver's brake valve 1 having a pipe connection 17 to atmosphere. In one embodiment, Fig. 1, the system is modified by a connection 15 between a reservoir 13, fed with compressed air by a pump 11, and an additional valve which is incorporated in the driver's valve 1 and actuated by a latching lever 23 on the handle 21 of the valve 1 for controlling the supply of compressed air to the pipe 9 to accelerate braking action. The lever 23 is arranged so as to be operable only in the braking or lap positions of the valve 1 and inoperable in the running and released positions. In a second embodiment, Fig. 2, a compressed air reservoir 27 is provided which is automatically replenished in the running and released positions of a modified driver's valve 25, and which feeds compressed air to the train pipe 9 in the braking positions of the valve 25. The remainder of the system is the same as that of the first embodiment. In both embodiments a non-return valve 16 is inserted in the pipe 17 to prevent the passage of compressed air to atmosphere.

Title: Improvements appertaining to petrol tanks for motor road vehicles
IPC: B60K15/06
Filed: 1930-03-05
Abstract: 354,742. Petrol tanks float valves. SUTTON, C. J., 19, Nelson Square, Bolton, Lancashire. March 5, 1930, No. 7144. [Classes 69 (i) and 135.] In a motor road vehicle, a reserve petrol tank is so arranged that the main tank cannot be filled without filling the reserve tank. In one form, as shown in the Figure, a reserve tank 3 is formed in the main tank 2 by a partition 2a. After discharge of petrol from the main tank through the pipe 5, the reserve tank may be discharged through a pipe 6 by actuation of a valve 7 by means of a handle 8a. The valve 7 has a float 7a attached to it, and is rigidly connected to a weight 7b and short arm 7c, being pivoted at a. When the valve is opened by depressing the handle 8a, and so moving the arm 7c, the weight 7b passes over the pivot, and retains the valve in an open position until insufficient petrol remains to buoy up the float member 7a, thus closing the valve. In a modification the actuation of a spring-pressed valve allows the whole of the contents of the reserve tank to pass into the main tank for use therefrom.

Title: Valve device for supplying fluid to a plurality of  output lines
IPC: B60T11/32
Filed: 1973-02-14
Abstract: 1397372 Pneumatic control circuits KNORRBREMSE GmbH 14 Feb 1973 [14 Feb 1972] 7374/73 Heading F1P [Also in Division F2]  A valve device comprising flow control valves 6, Fig.1, connected to a supply line 2 and having outlets 3, 4, 5, has by-pass paths 7 which include throttles 8 in series with non-return valves 9. A control line 10 is provided. In operation, compressed air is supplied to the line 2 with the three circuits at atmospheric pressure and air flows round the valves 6 through by-pass paths 7 so that some filling of levies 3, 4, 5 occurs. The valves 6 are constructed to open when fluid pressure is present at the control inlet and the fluid outlet. Thus pressure build-up due to the throttles 8 promotes opening of the valves. If the compressed air supply fails, air can flow unthrottled from one line to another until the circuit pressure falls below the opening pressure of valves 6. If one line develops a leak, the valve 6 in that circuit will close when the pressure falls to atmospheric and the loss of compressed air through the by-pass line 7 will be small. The two intact lines will function normally. Fig.2, (not shown), illustrates a modified circuit. Fig.3 shows a four-line system with by-pass valves 22, 23, 24, 25, the valves 22, 23 incorporating shut-off valves 32. The latter ensure that lines 17, 18 are filled first when compressed air is supplied through line 16. Fluid passes through by-pass lines 28 until pressure build-up opens valves 22, 23 and with them valves 32. Flow now occurs through by-pass lines 31 until pressure build-up causes valves 24, 25 to open. Fig.5 shows a construction of the valve device in which two by-pass valves 42, 43 are illustrated. Operation is as follows. If the lines 17, 19 are at atmospheric pressure, compressed air from pipe 16 flows through bores 49, 50 into chambers 47, 48 below valve pistons 42, 43. Sealing ring 63 acts as a non-return valve. The pressure built up below piston valves 42, 43 is insufficient to open them against springs 44. From chamber 47 air flows through an annular gab 51, under a sealing ring 54 and through a throttling duct 56 into a bore 55 and line 17. The sealing ring 54 acts as a non-return valve. Pressure builds up in the line 17 and eventually the valve piston 42 is lifted so that there is a free flow of air into line 17. Air cannot flow from chamber 48 under piston 43 because of sealing ring 62. However, when piston 42 has been raised air passes through bores 60, 59, 61 past the ring 54, which acts as a non-return valve, through throttling duct 56 and into chamber 55 and line 19. Pressure builds up in line 19 and raises piston valve 43 so that there is unrestricted flow into line 19. The other half of the valve operates in the same manner.
