Title: Improvements in or relating to devices for protecting thermodynamic engines from excessively high temperatures
IPC: F02G1/055
Filed: 1960-02-08
Abstract: 934,634. Engine temperature monitoring apparatus. PHILIPS' GLOEILAMPENFABRIEKEN N.V. Feb. 8, 1960 [Feb. 11, 1959], No. 4363/60. Class 40 (3). [Also in Groups XXXV and XL (c)] In an apparatus for safeguarding a hot-gas engine, a safety valve is operated if the temperature in any cylinder exceeds a predetermined temperature. The device may also vary the setting of a fuel control valve in accordance with cylinder temperature variation. Each cylinder is provided with a temperaturesensitive device which is connected to an indicator, Fig. 1, calibrated in degrees. When one cylinder only is to be monitored the circuit of Fig. 2 is used. Three lamps 1<SP>1</SP>, 2<SP>1</SP>, 3<SP>1</SP> are placed such that they shine through holes 1, 2, 3, respectively, in the indicator face on to photo-transistors 5, 7, 6. A vane 4 mounted on the indicator needle interrupts the beam from lamp 3<SP>1</SP> when the cylinder temperature becomes too high, so that current in resistor 13 falls and transistor 9 becomes biased to cut-off. If the indicator needle falls to the zero position, the light from lamp 1<SP>1</SP> is interrupted, this also causing transistor 9 to be cut-off. In either case no current now flows in any of the lamps 1<SP>1</SP>, 2<SP>1</SP>, 3<SP>1</SP>, or in the control coil 11 of a safety valve, which therefore operates. Depression of a switch 8 switches the lamps on again. Under normal temperature conditions the vane 4 lies near the hole 2 and, as the cylinder temperature varies, so the amount of light falling on photo-transistor 7 also varies. This transistor controls, via a transistor 10, the current in a coil 12, which adjusts the setting of a fuel valve. Where more than one cylinder is to be monitored an indicator and a circuit similar to that of Fig. 2 are used for each cylinder. To ensure that faulty operation of any cylinder causes the engine to be stopped, the lamp circuit is modified, Fig. 3 (not shown), in that the lamps 2 and 3 of any one circuit are in series with the lamp 1 of the following circuit.

Title: Improvements in or relating to vehicle brakes
IPC: F16D65/46
Filed: 1925-02-17
Abstract: 231,438. Soc. Anon. des Automobiles et Cycles Peugeot. March 31, 1924, [Convention date]. Compensating for wear of the shoes of an internal expanding brake is effected by adjusting the position of the pivots of the shoes, the pivots being constrained to move along a path which is substantially concentric with the brake drum. In the form shown in Fig. 3, the pivots are supported by pairs of links N, O and P, Q connected respectively to an anchorage at the centre of the brake drum, and to a sliding member R the position of which may be adjusted by the screw and nut shown. The links P, Q may be displaced by a pair of screws adapted to be actuated by a nut having right and left hand threads, whilst by guiding the pivots of the shoes in arcuate slots and providing a guide in which the adjusting-nut may slide, the links N, O may also be dispensed with. The form shown in Fig. 6 provides for automatic compensation for wear. Upon a worm Z, the rotation of which adjusts the position nf the pivots of the shoes through the nuts and. screws shown, is mounted a ratchet wheel A<1> and a lever B<1> carrying a pawl C<1>. The lever is connected by a link D<1> to the cam-actuating lever E<1>, sa that when the displacement of the cam in a brake application is sufficient to allow the pawl to take up a tooth, the worm will be rotated by the pawl during its return movement. In this form, the pivots move in a straight line along tangents to a circle concentric with the brake drum and passing through the centres of the pivots in their initial position. The worin Z may be adapted for hand actuation.

Title: Integrated destination indicator
IPC: G01C23/00
Filed: 1961-02-08
Abstract: 985,976. Aircraft heading indicators. MINISTER OF NATIONAL DEFENCE OF H.M. CANADIAN GOVERNMENT. Feb. 8, 1961 [Feb. 15, 1960], No. 4704/61. Headings B7G and B7W. An aircraft heading indicator comprises a movable dial 13 driven by a motor 32 which forms a servo loop with a synchro transformer 25 and amplifier 33 to indicate magnetic heading, an adjustable command heading index 18 having piston control means, and a manually operable selector switch 135 arranged to change the heading source to a stand-by gyro, to render the index 18 inoperative, and to drive the dial through part of the position control means normally associated with the index 18. The stand-by gyro may be processed by pressing buttons 150, 151. As described, the operation of the switch 135 replaces the amplifier 33 by an amplifier 93, and switches in an auxiliary source of power to the motor 32. The command index 18 is driven by a motor 26 which forms a servo loop with the amplifier 93 and one of two synchro transformers 48, 49. Where the command input is a relative bearing, i.e. from radio compasses ADF1 or ADF2 as selected on switch 90, or from UHF equipment (not shown), the transformer 48 is used, but where the input is a magnetic bearing, from the aircraft navigator or from TACAN (NAV and TCN on the switch 90) the transformer 49 is used, connected to the index 18 through a differential drive 28, to which the heading motor 26 is also connected. The pilot may also select a command heading by means of a knob 100. A range counter 17, indicating e.g. distance from a target, is driven by a motor 123 responsive to the output of an amplifier 120, which compares signals from a potentiometer 121 driven by the motor and from the navigator or from TACHAN. This therefore only operates when NAV or TCN is selected on the switch 90, and at other times the counter is covered by a solenoid-operated shutter 129. A drift index 15 is also provided, driven by a motor 45 in a servo loop with an amplifier 46 and synchrotransformer 40 to which signals are supplied e.g. from Doppler radar equipment. Autopilot operation.-The aircraft may be turned by an autopilot to bring the drift and command indices 15, 18 into alignment by pressing a button 160 which connects a differential synchro 70 to the autopilot. The synchro 70 has a casing which rotates with the drift index 15 and a rotor which rotates with the command index 18, the error signal supplied to the autopilot therefore forming an analogue of the track error. A potentiometer 71 similarly has a casing rotating with the drift index 15 and a rotor rotating with the index 18, and has a missing segment so that when the indices are aligned the potentiometer forms an open switch, de-energizing a relay holding the button 160 in and isolating the autopilot. The output of the potentiometer 71 is also transmitted to a course indicator to act as a fine steering control. Specification 985,978 is referred to.
