Abstract: 166,625. Public Trustee, (Representative of Brindley, Sir H. S. B.). March 10, 1920. Turbines ; wheels.-Turbine-discs and wheels are made from gun-metal, wrought iron, cast or wrought steel &c. by extruding in successive steps. A billet h is forced by a plunger d between die members a, e to form a disc g; then the die e is advanced to reduce the extrusion opening and the extrusion completed. The die e is clamped during extrusion. and both dies may be actuated hydraulically, and may have discs f to guide the rim g. The work may be heated before the first, or both stens and the first step may be limited by a ring which is removed before the second step. The work mav be finally rolled, machined &c. to the required shape.

Title: Improvements in or relating to means for regulating the fuel supply to furnaces
IPC: F23N1/00
Filed: 1931-03-09
Abstract: 372,018. Regulating fuel supply to furnaces. ASKANIA-WERKE AKT.-GES. VORM. CENTRALWERKSTATT DESSAU UND C. BAMBERG-FRIEDENAU, 87, Kaiserallee, Friedenau, Berlin. March 9, 1931, No. 7284. Convention date, March 7, 1930. [Class 51 (i).] In a fuel supply regulator for furnaces of the kind ih which a regulating impulse determines the mean speed of an intermittently operating fuel feeding means by adjustment of the relation between the periods of fuel feeding and rest, the period of fuel feeding is varied relatively to the period of rest by relative displacement of two members normally in motion relatively to one another, the surface of one member having different characteristics in different parts thereof to which differences the second member is susceptible. In the form of regulating device shown in the Figure, a travelling grate 1 is driven by means of a constant speed motor 2 supplied with current by a switch member 3 constantly urged to open position by a spring 6. A continuously rotating cam cylinder 4, 4a capable of axial displacement in accordance with the value of a regulating impulse, such as the difference of pressure on two sides of a baffle in the combustion air supply-conduit, is adapted by means of its raised cam portion to move a link 5 and close the switch 3 to start the motor. The feed is interrupted when the link 5 engages the part 4 of the cam cylinder. The development of the curve between the portions 4, 4a of the cam cylinder is preferably in the form of a parabola. The regulating impulse may cause displacement of the link 5 instead of the cam cylinder and the link 5 may rotate about the cylinder instead of the latter rotating as stated above. The surface of the cam cylinder may comprise electrically conducting and nonconducting parts separated by a curve of the form referred to above and the link 5 may be replaced by a contact member with which the cam cylinder would form an intermittently operating switch to control the motor 2 directly or a clutch interposed between the motor and the grate. The cam cylinder 4, 4a may also operate a clutch between the motor and grate by mechanical means.

Title: Motorised drives for screw-operated valves
IPC: F16K31/04
Filed: 1955-03-12
Abstract: 788,007. Control of motors. FIRKINS, Ltd., G. & A., and FIRKINS, G. A. March 12, 1956 [March 12,1955], No. 7296/55. Class 38 (3). [Also in Group XXIX] An axially movable valve actuating spindle has a motor drive, the circuit of which includes two limit switches which operate to stop the motor at the ends of the spindle movement. In one example, Fig. 1, a motor 16 drives through a reduction gear-box 19 a pinion 20 which meshes with the toothed periphery of an actuating nut 21 which engages an external thread on a rotatable but axially fixed sleeve 22 the internal thread of which engages a complementary screw-thread on the valve actuating spindle 10. In operation the actuating nut 21 is held by opposed helical springs 27, 28 between contacts 17, 18 of limit switches in the circuit of the motor 16 and the sleeve 22 effects axial movement of the spindle 10. When the spindle 10 reaches the end of its travel the sleeve 22 is locked and the nut 21 moves axially against one or other of the springs 27, 28 and operates the appropriate limit switch contact 17 or 18 to stop the motor. In another example, Fig. 2 (not shown), only one of the limit switch contacts is operated by the actuating nut which is biased by a helical spring away from a plunger which actuates said contact. The other limit switch contact is operated by a plunger controlled by a crosshead fixed to the actuating spindle.

Title: Improvements in or relating to radio-location systems
IPC: G01S13/526
Filed: 1945-03-24
Abstract: 594,483. Radiolocation. GRAYSON, H., BROWN, D. E., and BARKER, G. C. March 24, 1945, No. 7514. [Class 40 (v)] In a pulse radar system, echo signals received in response to one transmitted pulse are compared, in a subtractive or opposing sense, with echo signals received in response to a subsequent transmitted pulse so that components of the echo signals which are repetitive in character cancel one another out. Echo signals from a moving target are caused to bear a modulation due to the Doppler effect which in general is not repetitive, and consequently, upon cancellation of the permanent echoes, the echoes from moving targets become apparent. The exploring pulse is illustrated in diagram (a). The echo signal (b) from a fixed target after demodulation appears as at (c). Diagram (d) shows the first of two pulses of diagram (c) delayed by the pulse recurrence period and inverted ; this signal is then added to the subsequent pulse of diagram (c) to produce substantially zero output as shown at (e). Diagram (f) shows echo pulses 14 and 15 from moving targets. Since pulse 14 is coincident with a pulse from a fixed target, the resultant pulse is modulated as shown in diagram (g), but in order to obtain the required Doppler " beat " from pulse 15 an oscillation 16, diagram (a) must be supplied within the receiver. The resultant signal shown at (g) is demodulated as shown at (h), the first pulses being delayed and inverted as shown at (i) and added to the subsequent pulses to produce the output (j). Since the modulation due to the Doppler effect is not dependent on the pulse recurrence frequency, the two sets of diagram (g) will in general not be repetitive and an output (j) will be obtained. If desired this process may be carried out before demodulation, either at the transmission or intermediate frequency. The output (j) may be presented on a cathode ray tube. The received echo signals are applied to one vertical deflection plate of a cathode ray tube, Fig. 2 (not shown), while the signals are also applied to the opposite plate of the tubes after being passed through a suitable delay device. In a system where the indication is obtained by modulation of a cathode ray beam, Fig. 3 (not shown), the echo signals are delayed and inverted and mixed with the original signals and then applied to diode rectifiers so that only a positive going output is obtained, the signals then being applied to the grid of a cathode ray tube. The delay device may comprise either an electrical network or a supersonic cell. It is desirable that the delay be adjustable to achieve the precise timing necessary. It is also desirable that the gain in one or both of the signal channels be adjustable. In place of the delay devices described, the signal may be recorded on a magnetic strip or photo-film and stored until an appropriate time at which to effect the comparison.
