Patent GB-621223-A (GB)
Title: Improvements in or relating to ultra-short wave receivers
IPC: H03D9/02
Filed: 1946-08-19
Abstract: 621,223. Radio receiving systems; valve circuits; detectors. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Aug. 19, 1946. No. 24713. Convention date, Aug. 20, 1945. [Class 40 (v)] In a micro-wave receiver a pair of micro-wave crystal or thermionic discharge tube detectors are coupled to a wave-guide structure of coaxial line section, or a pair of cavity resonators, in such a manner that the detectors are correctly phased and matched and proper balance obtained. A pair of input signal co-axial lines 1, 3 (Fig. 1), have their inner conductors 5, 7 terminated in a capacitive plate 9 and a coupling loop 11, respectively, within the centre portion of an enclosed wave-guide 13. The plate 9 excites similarly-phased electric fields and the coupling loop 11 excites oppositely phased fields in the ends of the wave-guide 13. Adjacent each end of the wave-guide are coupled two detectors 15, 31, matched to the surge impedance of the waveguide 13 by tuning screws 17, 19 and 39, 41 respectively. Detected signals from the detector 15 and 31 are coupled to an external circuit 20 by a conductor which is byepassed for radio frequency by two capacitive couplings 21 and 57 respectively to the wall of the wave-guide. If the input A is attached to a receiving antenna, and input B to a local oscillator, then by reason of the opposing polarities of the two detectors with respect to the output transformer, there is no output corresponding to amplitude modulation of either signal, whereas due to the reversed R.F. phase at one detector with respect to the other the heterodyne output component . of one detector is reversed and the two detected signals add, producing a pure beat signal. In a modification, Fig. 2 (not shown), a coaxial line may be used instead of the wave-guide 13. Matching adjustments are made on one detector at a time, the other being replaced by a load connected across the wave-guide at l, or m, m. If a pair of cavity resonators is employed instead of the waveguide 13, Fig. 3 (not shown), the two input lines are then terminated by a T-junction comprising in one case oppositely phased coupling loops and in the other similarly phased loops. The T-junction may also incorporate a loss introducing dielectric, Fig. 4 (not shown).

Title: Method of and apparatus for separating isotopes
IPC: H01S3/00
Filed: 1971-04-19
Abstract: 1355714 Mass separators; lasers JERSEY NUCLEAR-AVCO ISOTOPES 19 April 1971 [25 March 1970] 24757/71 Headings H1D and H1C Uranium isotopes are separated by illuminating a beam of uranium atoms with a first beam of radiation which selectively excites one isotope but not others, and with a second beam of radiation which ionizes the excited atoms, and then separating the ionized atoms from the non- ionized atoms. Fig. 2 illustrates a module used in the apparatus wherein uranium in a crucible 26 is heated to 2300 C. by means of heating elements 25 and the vapour is formed into a beam by a collimator 28. In the area 32 the beam is illuminated by a laser (not shown) operating at about 3900 which excites the U235 atoms and by a second laser operating at 2100-4300 which ionizes the excited atoms; non-ionized atoms are collected on plates 33-35 whilst the ionized atoms are deflected to the plate 36. The deflection system comprises the magnetic field between the polepieces 39 and 40 in conjunction with an orthogonal electric field (normal to the plane of the drawing) produced by electrodes (shown in phantom) at each end of the apparatus. The lasers may be pulsed for 10 nanoseconds at a frequency of 10 kHZ, and after each pulse the deflection system is pulsed for 1 microsecond, which is less than the mean free time for a charge exchange collision. A polepiece 41 co-operates with the polepiece 39 to provide a field across the collimator which prevents ions from passing from the oven to the area 32. The module is evacuated through port 4 and cooled by cooling pipes 8, and its cover 18 is removable. The module is long (1 metre) compared with its width and a large number are arranged along a common optical axis illuminated by common lasers so that all the radiation is utilized: the number required may be reduced by reflecting the beams so that they pass twice or more through each module. In the specific example illustrated (Fig. 1, not shown) two lasers are arranged at the same end of a column of modules, the beam from one being reflected into the column by a mirror which does not affect the other beam. The wavelength of the second laser may correspond to a transition between the excited state and an autoionization level of the excited atoms.

Abstract: 1,189,472. Radiation gauge thickness measurement. INDUSTRIAL NUCLEONICS CORP. May 30, 1967 [June 21, 1966], No.24788/67. Heading G1A. In a nucleonic arrangement for measuring the surface density of thickness of a sheet or film which may be running, in which pulses corresponding to radiation reaching the detector through the sheet or film, or due to back scatter, are accumulated, the total accumulated in a given period is modified to compensate for source decay, component value variation, and the presence of foreign matter by the radiation detected in the absence of the sheet. The measuring device may comprise a source-detector unit mounted for movement relative to the sheet, and provision may be made for periodic movement away from the sheet. The detected radiation pulses may be fed to a counter the accumulation period of which is adjusted by the "sheet absence" radiation, or they may be fed to an accumulating subtractor in a manner opposed to pulses from a generator, the generating rate of which is adjusted by the "sheet absence" radiation. A further arrangement may employ both pulse rate modification and accumulating period adjustment. Analogue comparison equipment in which a measured potential is compared with a standardizing potential may be used and the standardizing adjustment may be effected manually.

Abstract: The invention comprises 2-alkoxycarbamido-5 - sulphonamido - 1 : 3 : 4 - thiadiazoles of the general formula <FORM:0801394/IV (b)/1> where R is an alkyl (including cycloalkyl) or aralkyl group containing not more than 18 carbon atoms, and the manufacture thereof by treating 2-amino-5-mercapto-1 : 3 : 4-thiadiazole with one equivalent of an alkyl chloroformate in the presence of a hydrogen chloride abstractor, reacting the resulting 2-alkoxy carbamido-5-mercapto-1 : 3 : 4-thiadiazole in aqueous acetic acid solution with a slight excess of chlorine gas and the resulting sulphonchloride with liquid ammonia or concentrated ammonium hydroxide.  By reacting the starting material with two equivalents of an alkyl chloroformate a diacyl-1 : 3 : 4-thiadiazole may be prepared which on reaction with chlorine gas yields the sulphonchloride above.  In an example, sufficient pyridine is added to a suspension of 2-amino-5-mercapto-1 : 3 : 4-thiadiazole in dimethylaniline to dissolve the solid.  The solution is ice-cooled and ethyl chloroformate added.  The 2-ethoxycarbamido - 5 - mercapto - 1 : 3 : 4 - thiadiazole so prepared is suspended in 33 per cent aqueous acetic acid, cooled to 0 DEG  C. and treated with chlorine gas.  The resultant solid is then treated with liquid ammonia to yield 2-ethoxycarbamido-5-sulphonamido-1 : 3 : 4-thiadiazole.  In a similar manner is prepared 2-methoxy-, 2-benzyloxy-, 2-n-propoxy-, 2-n-butoxy-, 2-n-amyloxy- and 2-n-hexyloxycarbamido-5-sulphonamido-1 : 3 : 4-thiadiazoles. Examples are also given of the reaction of the starting material with ethyl, benzyl, n-amyl, and n-hexylchloroformates in pyridine and at 0 DEG  C. to form the corresponding diacyl compounds.  These are suspended in 50 per cent aqueous acetic acid and treated with chlorine gas, the sulphonchlorides so formed being treated, as above, with liquid ammonia to yield the sulphonamides.  Starting material. 2-Amino-5-mercapto-1 : 3 : 4-thiadiazole may be prepared by reacting thiosemicarbazide with carbon disulphide in aqueous alcoholic ethylene glycol solution in the presence of potassium hydroxide or in substantially anhydrous alcoholic media in the presence of an alkali.

Abstract: 750,519. Automatic gain &c. control. BRITISH TELECOMMUNICATIONS RESEARCH Ltd. Sept. 7, 1954 [Sept. 10, 1953], No. 25094/53. Class 40 (4). In an arrangement for regulating the gain, frequency or phase in a carrier current communication system, the discrepancy between a pilot current and a reference current is caused to vary the control current of a magnetic transductor the A.C. output of which is made to effect the necessary correction. The pilot current selected by a filter F, Fig. 1, is amplified and compared with a reference D.C. and the resultant current controls a network # in the feedback path of a line amplifier LA through a magnetic transductor MT. The pilot current applied at terminals T1, T2, Fig. 4, is amplified in pentode V1 and the output which is rectified in a voltage doubler MR1, MR2, is re-amplified in a reflex arrangement to control the transductor MT1. A D.C. reference potential is tapped off from resistor R2 across the H.T. supply and the A.C. output from the transductor controls a heater H1 of a thermistor TR1. A modified arrangement includes a pre-amplifier stage and has the transductor in the anode circuit of the second stage, Fig. 3 (not shown). In a further modification, Fig. 5, using a directly heated thermistor which is temperature-biased by an auxiliary theater, the magnetic amplifier MA comprises a control winding W1, a balanced polarizing winding W2 which is fed from a D.C. source via a potentiometer R13, and a balanced output winding W3 which is fed with A.C. by transformer T. The output is rectified in a bridge RB and the connection to thermistor TR3 includes a low-pass filter F4.
