Title: Digital synchronizing and phasing system
IPC: G05D13/24
Filed: 1973-03-23
Abstract: 1398498 Automatic speed control; centrifugal governors WOODWARD GOVERNOR CO 23 March 1973 [14 June 1972] 14268/73 Headings G3B and G3R The speed of a prime mover is measured and represented as the frequency of an electrical signal which is compared with a reference frequency signal by feeding the two signals to respective inputs of a bi-stable device. The bi-stable output controls the energization of a magnetic biasing coil in a governor so as to adjust the prime mover speed to a value corresponding to the reference frequency. As shown in Fig. 1, a reference signal is provided by the shaft 23 of a master aircraft engine 21 connected to a transducer 61 supplying pulses through a Schmitt trigger circuit 75 to a differentiator 77 which supplies trigger pulses to the set input of flip-flop 79. The reset input receives similar pulses from a transducer 62 associated with a slave engine 22. The resulting rectangular signal at the set output of flip-flop 79 switches a transistor 59 into saturation for intervals whose duration determines the mean current in a winding 57a which magnetically controls the setting of a governor in the fuel supply system for the slave engine 22. In another arrangement, Fig. 5 (not shown), the winding 57a is connected across a transistor bridge and is energized alternately in opposite senses by the set and reset outputs of the flip-flop. Fig. 7 (not shown) illustrates an arrangement for manually setting a required phase relationship between the two engine shafts using an operational amplifier receiving an adjustable reference current to control the current in the magnetic winding. The phase setting may be automatically regulated by including a further operational amplifier with an integrating characteristic, Fig. 8 (not shown). A further arrangement Fig. 10 (not shown), concerns the synchronization of two engines each controlled by a governor with a magnetic biasing winding. The windings are energized by complementary signals derived respectively from the set and reset outputs of a flip-flop. The construction of the magnetic speed governor is shown in Fig. 2. Flyweights 43, 44 may be permanent magnets or magnetic material such as soft iron, and their rotation about pivots 52, 53 is controlled by a spring 49 and by the energization of a winding 57a. The position taken up by the weights determines the relative positions of a valve plunger 47 and sleeve 46 which hydraulically control a fuel servosystem for the prime mover.

Abstract: 954,238. Voltage measurement. BRITISH WELDING RESEARCH ASSOCIATION. April 13, 1962 [April 24, 1961], No, 14752/61. Heading G1U. Apparatus measuring effective values of short wavetrains comprising a fast response energy converter as input a short wavetrain and giving an output attaining within the duration of the input wavetrain a substantially constant value which is a function of the input signal to be measured, an indicator of the output signal of the energy converter device, and storage or recording means whereby the indication representing the substantially-constant value is held available for a period after the converter output has reached such constant value, during which the input wavetrain may have terminated. In Fig. 1 short input wavetrains 4 derived e.g. from welding currents are applied to the filament of rapid response lamp 1 illuminating photo-cell 2, and a sinusoidal waveform from oscillator 6 energizes the filament of lamp 8 through variable gain amplifier 7 to illuminate photo-cell 10; the outputs of the photo-cells being differentially combined and amplified to vary the gain of amplifier 7 for equality; the time constants being such that balance is achieved before termination of each wave 4 and the period of the sinusoidal oscillation being < “ the repetition frequency of waves 4. A signal from output of amplifier 7 is applied to a long time constant of discharge peak voltmeter or to a long delay cathode ray oscillograph, indicating the effective value e.g. the RMS value over 1 cycle of the input wavetrain. For initial balance, amplifier 7 also energizes lamp 1 over switch 15 and potentiometer 13 is adjustable for zero combined output of the photo-cells. In Fig. 2 the input wavetrains 4 are amplified to energize lamp 1 illuminating photo-cell 2 whose output is amplified to excite peak voltmeter 3, and amplifier 5 is alternatively energized over switch 20 from a variable 50 c.p.s. source for equality of indication, at which the reading of voltmeter 23 indicates the effective value of the input wavetrain. The calibration cycle may be automatised, and the lamp and photo-cell arrangement is replaceable by a bolometer and heater.

Filed: 1932-05-24
Abstract: 401,762. Gas-fires; radiants ; burners. GAS LIGHT & COKE CO., MASTERMAN, C. A., and ANDREW, L. W., 84, Horseferry Road, London. May 24, 1932, No. 14770. [Classes 75 (i) and 126.] A gas-fire radiant comprises flat front and rear members 1 2 of equal widths and substantially equal heights the front member being apertured over the whole of its area whilst the whole or major area of the rear member is apertureless, conical pips 6 7 or other suitable projections being provided over the two facing surfaces of the members. In the construction shown flat side walls 3 connect the front and rear members and the rear member slopes slightly forwards, the radiant being thus in the form of a hollow block of rectangular horizontal section which diminishes in depth upwardly. The front member is of grid pattern. The products escape by an opening 9 extending across the top of the radiant, which may be replaced by a slit or a series of openings in either the top wall or the top of the rear wall. The conical pips 6 7 may be replaced by projections of other form such as ribs. The radiants are retained in position side-by-side in the stove by a refractory pin passing through apertures 13 in their side walls ; alternatively pins extending vertically upward from the burner tube may engage in vertical recesses in the side walls of the radiants. The radiants may be coloured by incorporating in them salts which on firing give coloured oxides ; e.g. cobalt nitrate, iron sulphate, or potassium bichromate to give respectively a blue, red, and green coloration. In the gas fire shown in Fig. 2 the firebrick back is formed with an arcuate portion 20 overhanging the radiants and merging into the flue 21. Fig. 11 shows a portable gas fire in which the side fire-bricks 25 are separately removable after the rear brick 23 has been removed by sliding it upwardly. Shoulders 28 29 on the side firebricks engage the outer face of the single radiant. Fig. 12 shows a gas burner for use with the radiants comprising two branches 31 32 closed by caps 37 38 each provided with two nozzles 39 40 below which are perforated steatite baffle discs 41 42.
