Title: Parametric amplifier circuit operating in a pseudo-degenerate mode
IPC: H03F7/04
Filed: 1967-02-22
Abstract: 1,105,849. Parametric amplifiers. COMPAGNIE FRANCAISE THOMSON HOUSTON-HOTCHKISS BRANDT. 22 Feb., 1967 [8 March, 1966], No. 8561/67. Heading H3B. A parametric amplifier 8 and a mixer 10 together produce an amplified output signal at a selected intermediate frequency value fm from a V.H.F. input signal fs, the mixer having both the output fi from the parametric amplifier and the signal frequency fs applied to one input from a circulator 6, and having a local frequency produced by an oscillator 20 and equal to (fsfm) applied to another input, the local frequency also being applied through a frequency doubler 18 to constitute the pump frequency fp of the amplifier. As the frequency relationships of the amplifier are: where fm<<fs, the arrangement is stated to operate in a pseudo-degenerate mode. As shown, the input signal fs is applied from an antenna 12 to the circulator through a bandpass filter 4 which passes only the input signal frequency fs and its modulation band. A further filter 14 is connected between the circulator and the varactor 16 of the amplifier which has a bandwidth sufficient to pass the input signal frequency fs, the idler frequency fi generated by the amplifier and the respective modulation bands. Energy reflected back from the mixer is absorbed in a load 12 connected to the circulator. The local frequency (fsfm) is applied to the mixer through a phase shifter which imparts the required 45 degrees phase difference.

Patent GB-549123-A (GB)
Title: Improvements in or relating to the control of hydraulic or other fluid-pressure operated presses
IPC: B30B15/16
Filed: 1941-07-10
Abstract: 549,123. Fluid-pressure presses. MILLS & CO. (LLANIDLOES), Ltd., J., and MILLS, R. G. July 10, 1941, No. 8734. [Class 69 (ii)] [Also in Group XXVI] In a hydraulic or other fluid-pressure press a spring-loaded ram 1 mounted in a press cylinder 2 acts in the first place to apply pressure to the press ram 19 and higher pressures are built up when the ram 19 is acted upon by fluid pressure admitted to the cylinder by a pipe 5 from a supply unit 6 comprising a low-pressure pump 7 and a high-pressure pump 9 driven by eccentric mechanism including an adjustable link 13. The ram 1 then acts in opposition to the fluid pressure. The building up of pressure in the press is at a rate depending upon the rate of discharge of fluid from the unit 6. The building up of pressure commences when a byepass valve 18 is closed, and the pumps then discharge fluid to the pipe 5 via spring-loaded valves 14, 15. When the ram 19 contacts with the work the valve 14 cuts out the low pressure system owing to the rise in pressure in chamber 16, which initially receives both the high and low pressure fluid. The low pressure fluid is then byepassed to the supply tank via a relief valve 20. The pipe 5 is fitted with a high pressure relief valve 21. The ram 1 may be loaded by a single spring 3 or by two or more rams, or by air-pressure. In a modification the work table 22 may be supported by a ram 1 in a cylinder 23 connected by a pipe 24 to the press cylinder 2, and springs 25 load the table against the action of the fluid pressure.
