Title: Improvements in or relating to cathode ray tube apparatus suitable for use in radar and like systems
IPC: G01S7/12
Filed: 1947-07-15
Abstract: 648,838. Electric indicating systems. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. July 15, 1947, No. 18869. Convention date, July 16, 1946. [Class 40 (i)] [Also in Group XL (c)] In cathode-ray tube apparatus wherein the ray is required to be subjected to a circular component of deflection in accordance with the orientation of a member whose orientation is continuously varying, the circular deflection is controlled by two carrier waves of different frequencies, one wave being frequency modulated in accordance with the sine of the angle of orientation and the other in accordance with the cosine, the waves being transmitted to the tube over a single channel during different predetermined time intervals. The invention is illustrated as applied to a remote P.P.I. display for a pulse radar system, and consists in modulating the frequency of two oscillators in accordance with sine and cosine of the aerial orientation and then transmitting the signals to control the sweep generators of the C.R. tube. In order that the radar synchronizing and range signals may also be transmitted over the same channel, the orientation signals are only transmitted for part of the radar recurrence period. Circuits at the aerial, Fig. 2. Oscillators 1 and 3 of ranges 1-1.1 mc./sec. and 1.5-1.6 mc./sec. respectively, are frequency modulated by condensers 5 and 7 mechanically coupled to the aerial axle xy. The frequency of oscillator 1 is varied as the sine of the aerial orientation and that of oscillator 3 as the cosine. A pulse recurrence period of 1000 microseconds is employed, the first 750 microseconds of which are allotted to the transmission of radar signals and thereafter two periods each of 125 microseconds are allotted to the sine and cosine frequency-modulated signals. To effect this allotment, the oscillators are normally held quiescent and rendered in turn operative each of 125 microseconds by grid-switching pulses derived from the anodes of multivibrator 81, 83, this multivibrator being itself operated 750 microseconds after the transmitted pulse by means of a further multivibrator 55, 57 triggered from the transmitter synchronizing signal. Gain control stages 97, 99 combine the oscillator outputs and transmit the signals through a clamp circuit 31. Circuits at the cathode-ray tube, Fig. 3. The radar range, synchronizing and orientation signals pass through receiver 107, and a blanking circuit 109 timed by synchronized trigger circuit 111 selects only the orientation signals for application to filters 113, 115. Filters 113 and 115 are tuned to oscillators 1 and 3 respectively and separate the sine and cosine modulation signals. Following each filter is a limiter and discriminator feeding an integrating detector, the potentials thereby derived being applied to control the deflection signal generators 117, 125. The deflection generators are synchronized with the transmitted signal by the synchronizing pulse which is extracted from the received signals by the circuit " sync pulse only".

Filed: 1962-05-17
Abstract: 953,809. Pulse generating circuits. SOC. DE PROSPECTION ELECTRIQUE SCHLUMBERGER. May 17, 1962 [May 19, 1961], No. 19125/62. Headings H3P and H3T. A circuit for generating a single cycle of sinusoidal oscillation each time a trigger pulse is received comprises a series-tuned circuit 1, 2 charged from a D.C. supply 8 via a switching device 11 and discharged via a second switching device 4 having a diode 7 connected in parallel opposition. The devices 4, 11 may be vacuum valves, transistors, thyratrons or equivalent semi-conductor devices. In Fig. 2, capacitor 1 is initially charged slowly via a trigger circuit 13 and inductor 2, a delayed-switching device 33 being provided to ensure that the pulse generator 6 is inoperative until the capacitor 1 is initially charged. Each pulse from generator 6 is lengthened at 34 and drives transistor 4 into conduction, discharging capacitor 1 resonantly via a load 3 and inductor 2. The negative halfcycle of discharged current passes via diode 7. At the end of each discharge cycle, the voltage at 15 causes a circuit 13 to trigger transistor 11 rapidly recharging capacitor 1 via inductor 9. In Fig. 3, capacitor 1 is initially charged via resistor 23 and inductor 2. When capacitor 1 is charged to the value of a reference voltage from source 24, the output from a voltage comparator 25 opens an AND gate 28 to allow trigger pulses from source 6 to reach the thyratron type semi-conductor 4 which provides a resonant discharge of capacitor 1 via inductor 2 and load 22, connected via a current transformer 21. At the end of each discharge cycle, the voltage at 15 is sufficient to cause a circuit 13 to trigger the thyratron type semi-conductor 11 which recharges capacitor 1 via inductor 2.

Title: Improvements in or relating to the preparation of esters
IPC: C07C67/14
Filed: 1952-07-29
Abstract: Esters are made by reacting an alcohol with an addition product of a carboxylic acid chloride and a metallic chloride of a tri-, tetra- or pentavalent metal and decomposing the resulting oxonium compound by hydrolysis or treatment with gaseous ammonia.  The alcohols may contain aliphatic, cycloaliphatic, arylaliphatic, terpenic or sterolic residues.  Stannic and titanium tetrachlorides and antimony pentachloride may be used as metallic halides.  With tetravalent metals oxonium complexes of two types are formed, one comprising two mols. of the acid chloride, one mol. of inorganic chloride and two mols. of alcohol and the other two mols of the acid chloride, one mol. of inorganic chloride and one mol. of alcohol, e.g. triphenyl carbinol.  Reaction may be effected with or without solvents. Solvents mentioned are carbon tetrachloride and carbon disulphide. When solvents are used the ozonium complexes are sometimes only slightly soluble in the solvents and separate spontaneously so that they may be isolated before decomposing.  In other cases the oxonium complexes may split in the solvents to yield the ester directly. Some oxonium complexes are unstable and decompose on formation to give the ester.  The esterification reaction takes place in the cold. A temperature range of 0-50 DEG C. is given for reaction.  The metallic addition product may be isolated before reaction with an alcohol or prepared and reacted in situ with the alcohol. Hydrolysis may be effected or completed with aqueous acids or sodium bicarbonate when the complex is decomposed in the solvent used.  When the complex is isolated it is subsequently hydrolysed in a solvent immiscible with water by means of aqueous acids or alkalis, e.g. sodium, potassium or ammonium carbonates or bicarbonates, or in the case of stable esters with dilute hydrochloric acid.  Where the ester is readily hydrolysed with water but is stable in the presence of ammonia decomposition of the complex may be effected with gaseous ammonia in an inert anhydrous solvent.  In examples, in which carbon tetrachloride is used as solvent: (1) triphenyl methyl acetate; (2) l-methyl acetate; (3) testosterone acetate; (4) d-bornyl acetate are obtained from the appropriate alcohol by treatment with the addition product of acetyl chloride and tin tetrachloride; and in (4) also with titanium tetrachloride; alternatively in (3) testosterone propionate is obtained from testosterone and the addition product of propionyl chloride and tin tetrachloride or antimony pentachloride; in (5) n-butyl benzoate is made by treating n-butanol with the benzoyl chloride addition product of tin chloride or antimony pentachloride; and in (6) methyl anthraquinone-b -carbonate is made by treating methanol with the addition product obtained from anthraquinone-b -carbonic chloride and stannic chloride.  Triphenyl carbonate is obtained as a by-product in (1).  In (1), (3) and (5) the complexes are isolated before hydrolysis.

Title: Improvements in or relating to pulse-responsive circuit arrangements
Inventor: BENNION ROGER HAROLD
IPC: H03K23/00
Filed: 1961-05-27
Abstract: 1,017,112. Electronic counters. AUTOMATIC TELEPHONES & CABLES Ltd. April 27, 1962 [May 27, 1961], No. 19204/61. Heading G4A. A counter or distributer comprises a number of stages each consisting of a two-input AND gate and a two-state buffer amplifier, two complementary waveforms being applied to one input of the AND gates of alternate stages, respectively, the other input of the AND gate being received from the output of the preceding buffer amplifier. A pair of stages is shown schematically in Fig. 1 and the wave-forms A, B applied to terminals TA, TA in Fig. 2. A start pulse Z coinciding with an earth pulse A passes gate G1 to operate buffer amplifier B1 which continues to conduct so that an earth pulse B operates G2 and B2. Fig. 3 uses four stages B1-B4 operating as already described in a build-up process. When B4 operates, however, its feed-back M removes earth condition from gate G1 so that B1 changes back to normal condition followed by B2 since TA is at earth. The fifth pulse with TA at earth returns B3 to normal and the sixth pulse returns B4. According to whether the number of stages is odd or even, the maximum count is 2N-1 or 2N-2. Count of 2N with N stages, Fig. 4. In each of the four stages shown, initially the oddnumbered transistor such as T1 is conducting and the even-numbered such as T2 is non- conducting. The 2-gate for the first stage is formed by resistors R1, R2. Diode DY is initially forward-biased to apply earth to the left-hand end of resistor R2. The first earth pulse on lead TA passes over diode D1 and resistor R1 to cut off T1 whereupon T2 conducts and maintains T1 at cut-off. Build-up of reversed state along the stages occurs with successive pulses on TA and TA. At the fourth pulse diode DY is back-biased but TA forward biases diode DX. When the pulse on TA ends DX is again back-biased and T1 conducts despite the earth pulse on TA. Successive stages now return to normal as the successive pulses on TA, TA end so that after 8 pulses the circuit is again normal. The circuit is applicable to counting dialled impulses in a telephone system.
