IPC: F04D29/06
Filed: 1960-01-13
Abstract: 876,701. Elastic-fluid turbines; stuffing-box substitutes; stop gear. WORTHINGTON CORPORATION. Jan. 13, 1960, No. 1217/60. Classes 110 (3), 122 (4) and 122 (5). [Also in Group XXXIV] A turbo-driven waterpump comprises a shaft 1, Fig. 1, having an impeller 6, a turbine rotor forming part of a turbine 2, and an auxiliary impeller 18 thereon. The shaft is supported by bearings 4, 5, the latter being cooled and lubricated by water drawn from the pump inlet 10, through passages in the impeller and the casing 13, by the auxiliary impeller, and then discharged through a pipe 21, Fig. 2, a filter 22, a cooler 23, and thence to the bearing 5 through a pipe 24. Some of the water is diverted through a pipe 25 to a unit 26, which controls the turbine by maintaining the desired steam supply pressure to the turbine, controlling the operating speed, and shutting off the steam supply in response to pressure conditions in the pump. To shut down the turbine when the suction in the pump varies from a predetermined value as sensed through a line 29, water passes through the unit 26, into a pipe 31 and thence to a servomotor 32, Fig. 1. The latter then closes a valve 33 on to a seat 33a which shuts off the steam supply to the turbine. The turbine end of the shaft is sealed at 37, 38, thus forming a chamber 36 to which a pipe 35 is connected, and a vacuum is produced in this pipe by an eductor unit 28, Fig. 2, operated by water passing through a pipe 27 into the unit.

Title: Improved means for driving and lining tunnels
IPC: E21D11/10
Filed: 1944-02-03
Abstract: 582,725. Tunnels. WILSON, A. D. G. Feb. 3, 1944, No. 2010. [Class 85] In driving and lining tunnels, rolled steel sections are built up into ribs of circular or other form on which removable arched shuttering plates are supported by spring clips on the shuttering plates co-operating with cover-plates wider than, and secured to, the inner flanges of the rib sections, which shuttering plates support the concrete of the lining as it is positioned. In a circular tunnel driven by a double shield as in Specification 580,047, circular ribs are built up of arcuate I-beams 1 connected as by fish-plates 2 ; a cover-plate 3 is bolted to, and is wider than, the inner flange of each rib, the plates 3 being adapted to support removable flexible arch plates 5 furnished with spring clips 6 engaging the plates 3. Each arch plate &c. 5 has on one edge a welded strip 5<x> adapted to overlap the adjacent plate 5. Before a new rib 1 is positioned and the rams 8 for advancing the shield are retracted, wedges 10 are inserted into holes 11 in the tail 9 of the trailing shield and bear against the previous rib 1 ; further wedges 12 are inserted between said previous rib 1 and the tail 9, the wedges preventing rearward movement of the trailing shield under pressure of the rams which advance the forward shield, and also preventing forward movement of said rib 1 under pressure from the deformed arch plates and wet concrete in the previous section. The new rib 1 is then positioned by the rams of the trailing shield, the arch plates 5 are inserted and concrete filled in behind the arch plates; at the roof of the tunnel, one or more apertured arch plates 13, Fig. 3, are inserted which are provided with a sliding plate 14 carrying a length of hose 15 through which the concrete filling is completed, the apertures being then closed by further sliding plates 16. When rams 8 are operated to advance the trailing shield, they also act through the forward ring 1 to flex the arch plates &c. 5 and force the new concrete into the space previously occupied by the tail of the trailing shield.
Patent GB-432114-A (GB)
Title: Improvements in or relating to traffic control signals
IPC: G08G1/082
Filed: 1934-01-20
Abstract: 432,114. Road signals for controlling traffic. AUTOMATIC ELECTRIC CO., Ltd., Strowger Works, Liverpool, PREIST, T. P., 104, Deveraux Drive, Poulton, Wallasey, Cheshire, and RENSHAW, A. P. B., Brookwood, Dickerage Road, Kingston Hill, Surrey. Jan. 20, 1934, No. 2082. [Class 118 (ii)] In a vehicle-controlled road-traffic signalling system in which two approaches are always given right of way together, the operation of the pads in the two approaches have different effects on the timing equipment. As described, the system comprises two intersections and is arranged so that traffic passing one intersection and approaching the second intersection reduces the maximum timing period for the cross-road, whilst traffic approaching the second intersection in the opposite direction does not have this effect. The system also provides for an increased amber period when right of way is forcibly removed from a crossing, and de-energizing circuits for the road relays to prevent sticking. The basic system is similar to that described in connection with Figs. 3 and 4 of Specification 403,732. When a vehicle passes over crossing X (Fig. 1) it operates pads XA1 and YA2 in succession. Pad XA1 [Phase A1 (Fig. 2)] controls, through relay E the movement of the cam shaft into positions 5 and 6 so that cam contacts C8 in the X intersection controller are closed. Pad YA2 operates phase A2 contacts in the Y controller so that relay F operates and locks. As the contacts C8 in the X controller are closed, relay G pulls up so that if the Y controller is in either position 2 or 3, giving right of way to the cross road, the reduced maximum timing circuit is completed over switch RMX. Condenser QB charges almost immediately so that relay B is energized to step the cam shaft through position 4 (amber signals) to position 5 to give right of way to the main road. Had pad YA1 been operated by a vehicle approaching the second crossing in the opposite direction, the vehicle operating XA1 turning so that pad YA2 was not crossed, relay D would have been energized and not relay F, to initiate transfer of right of way, but relay G would not have been affected and the maximum timing period would not have been altered. When the right of way is forcibly removed from a route, the short-circuit across either YG or YF is removed by a contact of relay D, E or F to increase the amber period whilst contacts S3 of the stepping magnet co-operate with contacts of relay B to energize one of the relays D or F to ensure return of right of way to that route. Resistances YJ, YK are connected in series with relays D and E and F respectively so that if one of these relays sticks when its locking circuit is opened, alternating current neutralizes the residual magnetism in the relay during the appropriate half-cycle.
