Patent GB-582548-A (GB)
Title: Improvements in vibration analysers
IPC: G01H1/00
Filed: 1944-05-12
Abstract: 582,548. Current measurements. WESTERN ELECTRIC CO., Inc. May 12, 1944, No. 9183. Convention date, April 15, 1943. [Class 37] [Also in Group XIX] A vibration analyser comprises means for selecting a vibration component, produced by the device (e.g., aeroplane engine) under test, of a frequency bearing a predetermined relation to the fundamental frequency of the device, corresponding to its speed of rotation, and indicating the value of the amplitude of this vibration component as the rotational speed of the device is varied over a desired range. The alternating voltages of a tachometer 4, proportional to the speed of an engine 2 is amplified and rectified by a component 32. A voltage-responsive device 35 supplied by amplifier 32 controls the movement of a chart 38, moving it between two extreme positions as the engine speed varies between extreme values (e.g. 300 r.p.m. to 3,000 r.p.m.). Voltage from the amplifier 32, stepped down a predetermined amount by potentiometer 37, operates a device 36 which adjusts a variable condenser 23 to vary the frequency of an oscillator 13 over a relatively small range (e.g., normal frequency 92 kc/s increased to a maximum of 92.5 kc/s). A vibration pick-up 10 is connected by a switch S1 to an amplifier 11 by which the complex electrical wave from the pick-up is amplified and transmitted to a balanced modulator 12 to modulate the output of an oscillator 13. A filter 14 passes only a narrow band of frequencies (e.g., 4 cycles per sec. wide centred at 92 kc/s.). Thus if, for example, oscillator 13 is tuned to 92,050 cycles per sec., the 50 cycle component of the output wave of amplifier 11 produces a lower sideband of 92 kc/s. which is passed by the filter 14 to be applied to a demodulator 15. A further filter 18 suppresses traces of oscillator voltage and, after passing an amplifier rectifier 19, current operates a pen control 53 to record the value of the amplitude of the selected vibration component. Thus, according to the setting of a tap 41 on the potentiometer 37, the frequency of the oscillator 13 is increased by a frequency equal to half, or double &c. the frequency (rotational speed) of the engine, and the vibration component of corresponding frequency is selected and its amplitude recorded by the pen 20. By running up the engine through a selected speed range each time a new position is selected on the potentiometer 37 a series of curves will be traced representing amplitude against frequency (or engine speed) for each vibration component selected. U.S.A. Specifications 1,976,481, 2,003,913, 2,088,439 and 2,147;729 are referred to.

Title: A Mechanism for Producing Power by the Compression of Gases, and Worked by the Explosion of Gases or other Substances.
Inventor: INGLEBY JOHN CONRAD BEDFORD
Filed: 1916-07-04
Abstract: 107,634. Ingleby, J. C. B. July 4, 1916. Actuating pumps by fluid-pressure.-The apparatus comprises a double-acting cylinder A with a loose piston D driven by explosions and when double acting as shown compressing the combustion products into a reservoir P, but when single acting, air. When the apparatus has been started the momentum of the piston compresses a charge in one end of the cylinder where it is ignited by a spark between the insulated electric terminal R and the piston. The explosion drives back the piston and, on the uncovering of the ports N by the piston, products escape past a valve into the reservoir. The fall of pressure behind the piston causes air and gas to enter through the ports K and these gases are compressed by the return of the piston under the influence of the explosion in the other end of the cylinder. To start the apparatus both ends of the cylinder are primed through cocks S and ignited by a sparking plug T. Passages 0 are open to the atmosphere for the escape of products of combustion and are closed gradually as the apparatus attains its normal speed of working. When air is compressed in one end of the cylinder the exhaust ports' 0 are situated further from the other end than they are shown. The piston is returned by the expansion of air which is trapped in the pump end. A modified apparatus also is described. Reference has been directed by the Comptroller to Specifications 2000/67, 3690/67, 1537/70, 3191/76, 1990/80, 3375/82, 9194/99, 24320/05, 4984/11, 18465/11, and 28187/11.

Title: Improvements in thermionic valve oscillation generators
IPC: H03J7/04
Filed: 1945-04-18
Abstract: 590,764. Valve generating circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. April 18, 1945, No. 9741. Convention date, April 19, 1944. [Class 40 (v)] In a variable frequency oscillator an inductive and a capacitive reactance valve circuit are connected together to give effectively a parallel resonance circuit with a negative power factor so that oscillations are sustained at a frequency depending on the impedances of the circuits. Fig. 7 shows valve 21 in an inductive reactance circuit in which resistor 23 has an impedance much greater than capacitor 25 to provide a phase, shift of nearly 90 degrees between anode and grid voltages, while network 29, 34 gives a slight additional phase shift required to produce a negative power factor. Similarly, in the capacitive reactance circuit associated with valve 41, capacitance 43 has an impedance much greater than resistor 45 and net work 47, 49 gives the additional phase shift required. Oscillations build up until grid current or anode saturation raises the net power factor to zero and the frequency is controlled by the variable bias on valve 21. The output is preferably fed to load 57 from the grid of valve 21 through buffer amplifier 61. In a modification (Fig. 8, not shown), triodes 21, 41 are replaced by pentodes and the output may be taken from either the screen or control grid of valve 21.
