Title: Improvements in or relating to radar apparatus
Inventor: WHITE ERIC LAWRENCE CASLING
IPC: G01S7/298
Filed: 1959-07-04
Abstract: 952,737. Cathode-ray tube circuits; pulse radar. ELECTRIC & MUSICAL INDUSTRIES Ltd. June 22, 1960 [July 4, 1959], No. 23043/59. Headings H4D and H4T. [Also in Division G4] In a radar system in which the display device is remote from the transmitter aerial 1, Fig. 1, two groups of digital signals, produced by a photo-electrically sensed coded disc 4 rotating synchronously with the aerial and representative of the sine and cosine of the angular position of the aerial, are transmitted to the display device (e.g. by radio) to control the positioning of a cathode-ray tube beam. As described, each sync. pulse transmitted by the radar aerial causes the signals then being sensed from the coded disc 4 to be transmitted to and registered 13, 14, Fig. 2, at, the display device. The display device also receives the sync. pulse transmitted by the radar aerial and it is effective to zeroize two counters 15 and 16. Thus at the instant a sync. pulse is transmitted by the radar aerial the angular position of the aerial is registered 13, 14 at the display device and also two counters 15, 16 are cleared. The outputs from the registers 13 and 14 pass to gates GA and GA1, respectively, which also receive pulses from a chain of frequency dividers 24, and the arrangement is such that in any time period during which the gate GA12 associated with the lowest denominational stage of the register 13 receives one pulse, the gate GA11 associated with the next stage receives two pulses and so on, the gate GA1 receiving 2<SP>11</SP> pulses, and thus in this time period the number registered in register 13 is transferred once to counter 15. A similar operation takes place with respect to counter 16. Thus on the occurrence of a radar sync. pulse counters 15 and 16 are cleared and pulses are entered into them at such rates that the ratios of the two numbers on the counters remains constant, equal to tan #, where # is the angular position of the radar aerial. The outputs of the two counters via gates GB and GC, and GB1 and GC1, and binary weighted resistors R and R1, cause two D.C. potentials to be developed by amplifiers 17 and 19, the two potentials both uniformly increasing with time and bearing a constant ratio of tan # to each other. These potentials are applied to the x and y deflecting plates of a cathode-ray tube 21 and their effect is to move the beam uniformly radially outwards from the centre in the direction #. The beam is only brightened however by the echo pulse received by the radar aerial and thus the spot produced on the cathode-ray tube represents both the range of the object causing the echo and also its angular position. The Specification mentions that marker pulses from a device 33 could be interleaved with successive sync. and echo pulses by means of a multiplexing switch 41, and that the pulses received from the radar aerial instead of being used to control a cathode-ray tube could be entered into a digital store.

Abstract: The invention comprises compounds of the formula <FORM:0749198/IV(a)/1> (wherein R is hydrogen, an alkali metal or a hydrocarbon radical containing up to eight carbon atoms inclusive, and R1 is an a - or b -hydroxyl group or ketonic oxygen), and a process for the preparation of a steroid D 17(20)-unsaturated-21-oic acid of the formula St = CH.CO2H or a salt or an ester thereof (wherein St is a cyclopentanophenanthrene nucleus attached to the side-chain at C17) by contacting a steroid of the formula St1.CO.CX2.CO.R (wherein X is chlorine, bromine or iodine, St1 is a cyclopentanophenanthrene nucleus attached to the side chain at C17 and having a 17-hydrogen atom, and R is hydrogen or -COO hydrocarbon) with a base, in the presence of hydroxyl or alkoxide ions.  The intermediate dihalo compounds are prepared from compounds of the formula St1.CO.CH:C(OM)R wherein M is hydrogen or an alkali metal, by treatment with chlorine, bromine or iodine, and the two-stage process may be effected without isolation of the intermediate dihalo derivatives.  Specified bases for the process are alkali metal alkoxides, hydroxides and carbonates, potassium propionate, basic ion-exchange resins and quaternary ammonium hydroxides, and an additional source of hydroxyl or alkoxyl ions, e.g. water, and the lower alkanols is normally employed.  In examples (1) 11-keto-21:21-dibromo-21-ethoxy-oxalylprogesterone is treated with methanolic sodium methoxide, the mixture diluted with water and 3:11-diketo-4:17(20)-pregnadien-21-oic acid methyl ester isolated by methylene chloride extraction and chromatography.  Other esters are similarly prepared using the appropriate sodium alkoxide. (2) As in (1) using aqueous potassium hydroxide as the base yields the corresponding acid as its potassium salt.  (3) 3:11 - diketo - 4:17(20) - pregnadien - 21-oic acid is similarly obtained from an 11-keto-21:21 - dihalo - 21 - ethoxyoxalyl - or 21-formylprogesterone.  (4) The sodium enolate of 11 - keto - 21 - ethoxyoxalylprogesterone is brominated in the presence of potassium acetate, and then treated with methanolic sodium methoxide to yield the methyl ester of 3:11-diketo - 4:17(20) - pregnadien - 21 - oic acid.  Other examples describe the preparation of 3a -hydroxy - 11 - keto - 17(20) - pregnen - 21 - oic acid and its methyl ester; 3-keto-4:17(20)-pregnadien-21-oic acid methyl ester; 3a :11a -dihydroxy - 17(20) - pregnen - 21 - oic acid methyl ester; 3 - keto - 11a  - hydroxy - 4:17(20)-pregnadien - 21 - oic acid and its methyl ester; 3 - keto - 11b  - hydroxy - 4:17(20)-pregnadien - 21 - oic acid ethyl ester; 3b  - hydroxy - 11 - keto - 17(20) - pregnen - 21 - oic acid ethyl ester; 3a  - acetoxy - 11b  - hydroxy-17(20) - pregnen - 21 - oic acid; 3b  - acetoxy-11 - keto - 17(20) - allopregnen - 21 - oic acid methyl ester and 3-keto-9(11)-oxido-17(20)-pregnen-21-oic acid propyl ester.

Title: Process for the preparation of dispersions of halogenated rubber
IPC: C08C19/14
Filed: 1947-08-27
Abstract: A halogenated synthetic rubber dispersion is prepared by introducing a halogen into an acid-resistant synthetic rubber dispersion which has been treated with an acid until a normality of at least 1 and preferably 3 or more is obtained.  The dispersion is preferably acidified with a hydrogen halide having the same halogen atom as that with which the rubber is halogenated, and the halogenation preferably takes place by introducing halogen at a temperature of between 0 DEG and 40 DEG  C., and then introducing further halogen between 70 DEG and 100 DEG  C.  The reaction may be accelerated by irradiation with normal or ultraviolet light.  The rubber dispersion utilized may be rendered acid-resistant by the use of a cationic soap or a neutral emulsifying agent such as a compound of the polyglycol ether type, or there may be employed a latex which has been obtained by the emulsion polymerization method.  The halogenated rubber may be obtained from the dispersion by centrifugal action, evaporation of the water or by precipitation with an organic solvent such as methanol or ethanol or with alkaline reacting solutions.  The synthetic rubber may be polyisoprene, polybutadiene, polydimethylbutadiene, polychloroprene, polyisobutylene, polymethylpentadiene, or may be isoprene - isobutylene, butadiene - styrene, or butadiene - acrylonitrile copolymers.
