Title: Improvements in or relating to methods and apparatus for detecting a high frequency signal
IPC: H03D9/04
Filed: 1939-03-17
Abstract: 530,870. Thermionic valve detecting circuits. LELAND STANFORD JUNIOR UNIVERSITY, BOARD OF TRUSTEES OF. March 17, 1939, No. 11655/40. Convention date, April 14, 1938. Divided out of 530,785. [Class 40 (v)] A high frequency signal is detected by being impressed on an oscillating field associated with an electron stream whereby cyclic variations in velocity are imparted to the electrons resulting in bunching or grouping. In this way after the grouped stream have passed through a second oscillating field with which it has interchanged energy the electrons are segregated in accordance with their individual velocities. The oscillating field may be produced in an internally resonant hollow body as described in Specification 517,264. The Figure shows an electron emitter 1 arranged to project an electron beam through hollow resonant bodies 5 ... 8 containing pairs of spaced grids 15 ... 18 which produce velocity grouping. At the output a plate 32 may be negatively biased so that only electrons of more than average velocity strike it or the plate may be positively biased so that only electrons of less than average velocity fail to strike it. The electrons impinging on the plate produce voltage across resistor 53 while the electrons passing through the aperture in the plate 32 may be observed on fluorescent screen 34 and produce a luminous path the length of which varies with signal amplitude. Biased rods 33 or a magnet 35 may be used to concentrate the beam striking the screen 34. The discharge space is sealed to maintain a vacuum while the hollow bodies are adjustably tunable by dipole 36 or coil 37 or by condensers 43, 44 associated with a coil 38 or dipole 39. The bunching of the electrons at the grids may be effected as described in Specification 523,712. Alternatively the beam may be deflected as described in Specification 529,771. Resonant hollow bodies 74, 77 coupled by loops 88, 89 and associated with an electron source 71 comprise an oscillator which is coupled to the hollow body 8 to enable phase modulated signals to be detected. A conducting tube 75 has a potential applied to it from an amplifier 96 dependent on the detected signal. Specifications 518,015, 530,785, 530,869, 530,871 and 531,067 also are referred to.

Abstract: 755,352. Operating clutches and brakes. LEHR, A. W. April 23, 1954 [April 25, 1953], No. 11765/54. Class 80(2) [Also in Group XXXI] In a mechanism for the use of disabled persons whereby the clutch pedal K, Fig. 1, and brake pedal B of a vehicle are controlled by a hand lever H, the clutch is disengaged by a spring 5 on the release of a catch 3, and is re-engaged by swinging the lever H against a force representing the difference between the spring 5 and the normal clutch spring (not shown). The mechanism is mounted in front of the driver's knees and the lever H passes through a transversely-movable slide 8. The lower end of the lever H is pivoted to a cranked rod (not shown) which is itself pivoted to the vehicle floor and engages a fork on the brake pedal B, so that the brake is applied by a direct push. The clutch pedal K is pivoted to a rod 9 coupled by rack teeth and a pinion 11 to a slidable rod 1 attached to the adjustable spring 5. In the clutchengaged position shown the catch 3 contacts an abutment 2 on the rod 1 to hold the spring 5 tensioned. On release of the catch 3 by the device 4, the spring 5 moves rod 1 to the right and disengages the clutch. The abutment 2 then contacts the slide 8 so that when the clutch is to be re-engaged swinging of the lever H and slide 8 in the direction of arrow 13 returns the rod 1 to the position shown. The actuation of the accelerator may be combined with the lever H. In a modification a hand lever 24, Fig. 5, slidable in a pivoted sleeve 35, is linked to the brake pedal 30 so that the brake is applied by pushing the lever 24 through the sleeve 35 to the position shown, and the clutch pedal 29 has a rack and pinion connection with a shaft 31 which is rotated by a toothed segment 22 loaded by an adjustable tension spring 21. The segment 22 is linked to the sleeve 35 so that rocking of the lever 24 from the clutch-disengaged position shown rotates shaft 31 to engage the clutch and simultaneously tensions the spring 21 until a dead-centre position of the segment 22 is passed. To disengage the clutch the lever 24 is moved sufficiently to overcome the .dead centre, whereupon the spring 21 completes the disengagement.
