Patent GB-612578-A (GB)
Title: Improvements in or relating to the control of end clearances of rotors
IPC: F01C21/00
Filed: 1946-05-28
Abstract: 612,578. Rotary pumps. KEELAVITE CO., Ltd., and CHITTENDEN, G. E. May 28, 1946, No. 16185. [Class 110 (ii)] Axial clearances between the faces of a rotor and its containing casing walls are controlled by pressure fluid which increases the force acting on a rotor face or a piston on the shaft when that face moves towards its adjacent casing wall. The rotor may form part of a rotary engine, pump, or meter, or a rotary valve, and the rotor and casing faces need not be flat but conical, convex or concave. Fig. 1 shows a pump with gears D, D<1> which are formed integrally with bosses D<2> so that the circumferential surfaces of these bosses, and the bores in which they lie, constitute sealing areas between the working chamber of the pump and further bores around bearings E<2>. During operation, the pump delivers liquid under pressure from the delivery chamber C through the clearances between the end faces of the gears to ports H, J, K, L leading to chambers G, G<1>, G<2>, G<3>, which are substantially closed though a small continuous leakage can take place through clearances between the ports F and E<3>. If gear D tends to move to the left, Fig. 1, thus reducing the clearance between its left-hand face and the adjacent face of the casing A<1>, the flow of liquid under pressure to the port H, from delivery chamber C, will be reduced, this reducing the pressure in the chamber G. The increase in flow of liquid through port J, to the chamber G<1> builds up pressure therein and tends to force the gear D back to the right. End recesses A' communicate with a relief chamber A<8> through a bore E<4> and passages A<9>, A<10>. In a modification, Fig. 5, the gears are formed integrally with bosses O<2>, providing circumferential seals with casing parts A, A<1>, and are secured to shafts O<3>, supported in bearings P, carrying pistons P<1> to provide pressure chambers Q, Q<1>, Q<2>, Q<3> to which ports J, H, K, L lead. When gear O moves to the left, extra liquid flows through the port J, less through H, so that pressure builds-up in chamber Q. This causes piston P<1> to move to the right and carry with it, the gear O. In a further modification, liquid is supplied to the chambers Q, Q<1>, Q<2>, Q<3> through metering orifices from a source of high pressure. The liquid escapes continuously through passages at rates which vary with the end clearances between the gears and the casing walls.
Patent GB-161980-A (GB)
Abstract: 161,980. Krupp Akt.-Ges., F. April 21, 1920, [Convention date]. Void [Published under Sect, 91 of the Act]. Adding and subtracting apparatus; multiplying and dividing apparatus; totalizing-counters.-In a key-set and independently operated machine having a plurality of totalizing-counters, reciprocating rack-actuating mechanism and printing mechanism, means are provided for selecting the kind of calculation which is to be performed and for controlling the sequence of engagement of the totalizers and printing mechanism. In the arrangement shown, items can be added or subtracted on totalizers I, II, or III, or I and III, or II and III; sub-totals or totals can be transferred to the printing-mechanism from totalizers I, II, or III, or these can be transferred positively or negatively . from I or II to III. For multiplication or division the totalizer I acts as a revolutions-counting mechanism. The kinds cf problem are set out in a table or plan and a scale corresponding thereto is provided on the machine, which scale co-operates with a pointer or setting lever to set the machine for the particular problem. The setting lever (not shown) is mounted on a spindle r<1>, Fig. 7, which carries a toothed wheel R engaging a rack q<1> on a sliding carriage Q, and is provided with a locking-device to hold the wheel R in set position. The carriage Q, which is guided in the frame of the machine by rollers q<2>, Fig. 6, is adapted to slide on a shaft M which makes one revoluticn at each operation of the machine. A sleeve M<1> slidable on said shaft is rotatably supported in the side walls of the carriage, and carries a series of cam-discs A, Z, E, Fig. 5, and a toothed wheel M<2> which gears with a similar wheel N<1> on a shaft N also provided with cam-discs A, Z, E. These cams are effective for adding or subtracting, taking subtotals, and totals respectively, and vary in size to prevent incorrect operation. The cam-discs, which have been set by the movements of the carriage, engage rollers D mounted on arms C rigidly secured to shafts B which, when the machine is operated, are rocked to cause rods G to make an upward and downward movement, and through bell-crank levers H operate rods J to throw the gear wheels of the totalizer into or out of operative position with respect to the actuating racks. When performing multiplication or division the movement of the setting lever to one or other of these positions effects a sliding movement of the totalizer I in such a wav that its gear wheels are moved out of the plane of movement of the actuating racks into that of a rack U, Fig. 12, adapted to actuate the units wheel of the totalizer I one unit at each operation, the movement of the rack being limited by a projection engaging a slot V in the rack.

IPC: H03K19/12
Filed: 1952-06-27
Abstract: 713,902. Gating circuits. STANDARD TELEPHONES & CABLES, Ltd. June 27, 1952, No. 16250/52. Class 40 (6) The Figure shows a coincidence gate circuit in which signals to be gated are applied at inputs A and B and which appear at the output via rectifier W3 in dependence upon the value of a control voltage applied from the cathode circuit of the gas-discharge tube GT via valve V. When tube GT is not discharging its cathode is held near to earth potential so that valve V is non-conductive, rectifier W4 is blocked and the circuit has no inhibiting effect on the coincidence gate. When tube GT discharges valve V conducts so that rectifier W4 passes current via the anode-cathode path of valve V so that the anode of this valve falls to earth potential thus inhibiting the operation of the coincidence gate circuit. The output 1 from the cathode of tube GT may be applied to other coincidence gate circuits (not shown) rectifiers such as W5 preventing mutual interference between gates. In a modification the anode of valve V is held at a positive potential, when the valve is non- conductive by connecting the anode to H.T.+ via a resistor R7.

Title: Improvements in and relating to control equipment for electric locomotives
IPC: B60L15/04
Filed: 1937-06-11
Abstract: 496,590. Field control of D.C. motors. WHYMAN, F., . and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. June 11, 1937, No. 16320. [Class 38 (iii)] The motors M1-M4 of a locomotive are controlled by a master controller having a final position in which the motor fields F1-F4 are shunted by a circuit including inductance and resistance and the resistance is regulated by a drum-type controller D.C. positioned by a pilot motor PM under the control of a relay CR responsive to the motor current. With the motors M1-M2 connected in parallel movement of the master controller to a weak field position establishes a connection Y whereby the pilot motor PM is energized over interlock contacts L1 on the series-parallel switch and interlock contacts T1, T2. controlled by the master controller. The controller D.C. is thus operated from its position shown. Operating coils P1, P2, energized through interlock contacts L2 on the series parallel switch, close their contacts p1, p2 to connect diverter resistance R5 across the motor fields. As the controller DC is operated further coils W1-W5 are energized in a predetermined sequence to operate contacts w1-w5 and gradually weaken the motor fields until the motor current reaches a predetermined value and the relay CR opens its contact b1. If the motor current exceeds a predetermined maximum value the relay CR operates to close its lower contact b2. The armature connections of the motor PM are thus reversed and the motor returns the controller DC to strengthen the motor fields. Contact fingers C1-C3 on the controller DC operate as limit switches for the motor PM. Resistances R6, R7, are connected in series and in parallel with the motor PM, the resistance R6 being in parallel and the resistance R7 in series for one direction of operation of the motor, and the resistance R7 in parallel and the resistance R6 in series for the opposite direction of rotation.
