Title: Improvements in thermionic converter for converting electrical pulses to rectangular waves
IPC: G01S13/14
Filed: 1944-07-17
Abstract: 602,313. Frequency measurements. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. July 17, 1944, No. 13657. Convention date, March 30, 1943. [Class 37] [Also in Group XL (c)] In an instrument for measuring the recurrence frequency of pulses, a multivibrator pair of valves V2, V3 having a common cathode resistance, is arranged with the anode of valve V2 coupled over condenser C and resistance R to the grid of valve V3, the anode of which is connected through resistance 11 to the grid of valve V2, an indicator being connected across condenser C to measure the A.C. potential developed. Normally, valve V3 conducts, valve V2 being biassed off by the anode current of triggering valve V1 flowing in coupling resistance 11. Upon receipt of a positive pulse, grid current flows in the unbiassed valve V1, the trailing edge of the pulse driving the grid negative, thereby producing a positive pulse in the anode circuit which causes valve V2 to pass current, valve V3 being cut off by multivibrator action. When condenser C discharges sufficiently for valve V3 to conduct, valve V2 is again cut off by the multivibrator action. After the receipt of a few pulses, the rectangular output wave is approximately symmetrical, the times of charging and discharging condenser C being approximately equal. The A.C. potential developed across condenser C in this steady state is a function of the pulse recurrence frequency.

Abstract: 1,253,716. Abrading. ITEK CORP. 18 March, 1969 [8 April, 1968], No. 14085/69. Heading B3D. A method of producing a desired surface contour on a workpiece 16 comprises dividing an initial surface of the workpiece into an array of discrete adjoining surface areas 62, determining the total surface change required each area to produce the desired surface contour, performing a plurality of operations on the areas, each operation effecting a substantially uniform change in the relative elevation of the area with respect to the other areas, performing the operations in an orderly sequence wherein successive operations occur on adjacent surface areas in the array, and varying the total number of operations performed on individual areas in accordance with the determining step to produce the desired surface contour. In apparatus for carrying out the method, the initial surface 15 of the workpiece 16 is measured by apparatus 17 which may comprise a dial indicator, probe or interferometer and produce a picture 18 of the surface. The picture is compared with the desired surface by a computer 19 which feeds a controller 23 having lines 26, 27 for controlling the movement of a lap 28 in x and y directions, feedback being supplied by lines 24, 25 to the controller. The lap 28, Fig. 2, is rotatably driven by a motor 41 and carried by a plate 36 movable in the y direction along a guideway 33 by a belt 47 driven by a stepping motor 43. The guideway is movable along guides 34, 35 in the x direction by a belt 50 driven by a stepping motor 47. The feedback to the controller is effected by sensors 56, 57 associated with the belt drives. The motors 43, 44 are moved in steps by the controller so that the lap 28 removes a uniform depth of material at each area 62 and is moved in a path 63 from area to area until the desired contour of the surface is produced, the lap operating a number of times in each area according to the amount of material to be removed from the areas. In other embodiments, the change of elevation of the areas may be effected by grinding, polishing, vapour deposition or spray painting.

Title: Improvements in radar systems
IPC: B65H45/20
Filed: 1962-04-11
Abstract: 1,000,520. Pulse radar. COMPAGNIE FRANCAISE THOMPSON-HOUSTON. April 11,1962 [April 11, 1961], No. 14086/62. Heading H4D. In a pulse radar using the Doppler effect and the pulse compression techique, the emitted pulses are linearly frequency modulated successively and alternately in the positive and negative sense, and the received echo pulses are applied to a device wherein they are delayed in accordance with the instantaneous frequency of the pulse modulated carrier wave. With this arrangement the mean of the target distances measured by the two sets of pulses gives the true distance, and the difference between the two measured distances gives the Doppler frequency, i.e. the radial velocity of the target. In Fig. 1 a generator 6 produces Vto two high frequency voltages fo(- 2 +K), where to is the duration of each transmitted pulse, which are fed respectively to mixers 7 and 8. A low frequency driving oscillator 17 supplies a voltage K + Vt alternately to mixers 7 and 8, the outputs of which pass through filters 9 and 10 to mixers 11 and 12 which are supplied with a frequency Fo - fo from mixer 13. Thus the outputs of mixers 11 and 12 are the two linearly frequency Vto modulated pulses Fob (- respectively 2 - Vt) which are passed through an amplifier to the aerial 4. Received pulses pass to mixer 16 where they are mixed with either Fo +fo or Fo - Jo according to which type of pulse was transmitted, these frequencies being supplied by mixer 13 in the transmitter, the mixer 13 combining frequencies fo and Fo from oscillators 6 and 14 respectively to produce Fo +fo. The intermediate frequencies produced by mixer 16 are therefore fo - Vto/2 + Vt#Fo, where #Fo is the Doppler frequency, and these signals pass through amplifier 18 to a dispersive filter 27 which effects pulse compression. The output of filter 27 passes through one of the gates 20 or 21, controlled by the transmitter according to which type of pulse is being received, to a unit 22 or 23 which measures the apparent distance of the target. The two distances measured by units 22 and 23 are added in unit 24 to give the true distance and subtracted in unit 25 to give the radial velocity of the target.
