Title: Improvements in or relating to ultra high frequency electrical amplifiers and oscillators
IPC: H01J25/02
Filed: 1949-04-01
Abstract: 699,631. Velocity modulated tubes. MULLARD RADIO VALVE CO., Ltd., and KNOTT, G. March 31, 1950 [April 1, 1949], No. 8913/49. Class 39(i) [Also in Group XL(b)] An amplifier or oscillator comprises a hollow rectangular waveguide 1, Fig. 1, within which is arranged a stack of parallel conductive rectangular plates 2 lying at right angles to the electric field component of an H mode electromagnetic wave in the guide, the plates being secured directly to the guide at two opposite lateral edges to divide it into parallel slots, and an aperture 4 through the stack of plates through which an electron beam passes. The arrangement is such that electrons are cumulatively accelerated or decelerated at the gaps between the plates and are shielded from alternate half cycles of the input wave entering the left hand guide portion by the plates, so as to produce velocity modulation and bunching of the beam. The bunched beam generates an amplified output wave in the right hand guide portion. The guide may be closed at one or both ends by a conductive member or members so that the device functions as an oscillator with one or two resonant cavities. In a modification, Fig. 2 (not shown), the stack of plates taper away from the gun in progressively increasing and decreasing senses at the input and output sections of the guide respectively. This is stated to improve the impedance matching and to reduce feedback. In another modification, Fig. 3 (not shown), the device effectively comprises two separate guides and stacks of plates, the stacks being placed one on top of the other in registry, and the two guides carrying the input and output waves respectively. In another modification, Fig. 4 (not shown), the output is taken from a cavity resonator arranged at the side of a single stack of plates remote from the gun. In another modification, Fig. 5 (not shown), the guide is closed at both ends. The end closures may be conductive so that the device serves as an oscillator or may be provided with windows so that the device can be inserted in a waveguide system and function as an amplifier. In all forms the output may be increased by employing a plurality of beams co-operating with a similar number of apertures. The aperture or apertures or one or more sets of apertures are located at a position or positions of maximum electric field, e.g. centrally for an H 01  mode and at “, or both “ and ¥, of the width of the guide from one side thereof for an H 02  mode. The plates may be tapered towards both ends thereof in the longitudinal direction of the waveguide so as to improve the impedance matching.

Title: Fluid-operated clutch control arrangement
IPC: F16D48/02
Filed: 1956-03-22
Abstract: 813,774. Controlling clutches. FICHTEL & SACHS A.G. March 22, 1956 [March 24, 1955], No. 8952/56. Class 80 (2). In a fluid-operated clutch control system, speed-responsive means acts on two valves such that increasing speed increases the loading on one valve and decreases the loading on the other. A motor vehicle clutch is disengageable by engine suction led to a valve 15 closed by a spring 17 and transmitted to the clutch servomotor by a duct 26, a reducing valve 18 having a nozzle bore 28 primarily controls the admission of air at atmospheric pressure. Two valves 15 and 16 are acted upon by springs 13, 14 and a beam 12 moved under the influence of an engine-driven centrifugal governor 9. At idling speeds the beam 12 moves towards the valves 15, 16 compressing the springs 13, 14 to provide the maximum closing pressure on valve 16 and minimum closing pressure, against the action of spring 17, on valve 15. The valve 15 opens to admit suction to duct 26 to hold the clutch disengaged. Increasing engine speed causes the beam 12 to reduce the pressure on springs 13, 14 and thus modify the suction to the clutch servomotor by the increased closing pressure on valve 15 and reduced closing pressure on the atmospheric inlet valve 16, to produce a gradual clutch engagement. Slowing of the engine on clutch engagement increases the loading on the springs through the governor 9 to provide smooth takeup; the reducing valve 18 preventing the full flow of atmospheric pressure under such conditions. An electromagnet 23, connected through a switch with the gear-shift mechanism, actuates a change-over valve 20 through a plunger 24 to release the clutch on gear-change. Arrangements are described in which the valve assembly is adapted to be used for positive pressure clutch disengagement and for positive or negative pressure clutch engagement.

Title: Improvements in wireless telephony
IPC: H04B1/46
Filed: 1921-03-31
Abstract: 182,218. Whiddington, R. March 31, 1921. Thermionic modulating systems; combined transmitting and receiv ing arrangements -In an arrangement for combinec transmission and reception, the power valve only generates oscillations when the telephone is spoken into, and during transmission the receiving valve is rendered insensitive bv the dimming of its flament. In the sys. tem shown, a transmitting aerial 6 and a receiving aerial 14 are earthed at a common point E. The power valve is provided with a grid 1, on which speech variations are impressed from a circuit 9, and a second grid 2 for obtaining the necessary reaction between the anode and grid circuits 5, 4. Anode current is supplied from a direct source 8 connected across a blocking condenser 7. The coupling between the circuits 5, 4 is such that normally the valve is unable to oscillate, but when the telephone is spoken into the variation in grid potential causes a change in condition and modulated oscillations are produced in the aerial. The receiver is one of known type but has an inductance 18 and condenser 19, shunted by a resistance wire 17, inserted in the valve-filament circuit. This circuit 17, 18, 19 is tuned and coupled to the transmitting circuit, so that when signals are being transmitted induced energy in the circuit 17, 18, 19 heats the wire 17, the resistance of which rises and thereby dulls the filament and renders the receiving valve insensitive. The Provisional Specification states that grid leaks may be inserted before each of the grids 1, 2, and that chokes 15, 16 may be included in the filament circuit to prevent induced currents in the circuit 17, 18, 19 from reaching the filament.
