Patent GB-953080-A (GB)
Title: Improvements in or relating to rocketwise propelled projectiles of the unguided type
Inventor: DAVIES ERIC THOMAS JOHN
IPC: F42B15/00
Filed: 1957-07-29
Abstract: 953,080. Self-propelled missiles. MINISTER OF AVIATION. July 1, 1958 [July 29, 1957], No. 24024/57. Heading F3A. A rocket projectile is propelled by two concentric charges, the outer of which is the booster charge which provides the rocket with sufficient acceleration to reach a predetermined velocity, while the inner charge burns at a rate sufficient to maintain that velocity. The booster charge is coated with inhibitor at its outer surface and end edges so as to burn over the whole of the inner tubular face, and the combustion gases pass along the annular space between the charges to a ring of nozzles. The inner charge burns only at the rear end and discharges through a single nozzle centrally situated within the first ring of nozzles. The outer nozzles may be inclined to spin the rocket.

Title: Improvements in and relating to the insulation of electric conductors
IPC: H02K3/34
Filed: 1936-09-02
Abstract: 460,130. Transformers; insulation for dynamo-electric machines. BRITISH THOMSON-HOUSTON CO., Ltd. Sept. 2, 1936, No. 24062. Convention date, Sept. 4, 1935. [Classes 35 and 38 (ii)] Electric coils, particularly for liquid-immersed apparatus such as transformers and induction regulators, comprise a bundle of insulated conductors 2 bound together by a covering comprising superimposed layers of paper and a cellulose ester material. The covering may be applied in the form of wrappings of paper tape 3, 5 alternating with oppositely wound wrappings of cellulose acetate tape 4. Cellulose acetate may also be used as the insulation between individual conductors. The completed coil is treated to remove moisture and gas, and is specially applicable to slot-wound induction regulators immersed in oil or in a non- inflammable dielectric such as chlorinated diphenyl in combination with trichlorbenzene. Specification 430,121, [Group XXXVI], is referred to.

Title: Rotary vise for an electrolytic grinding machine
Inventor: ROBISCHUNG PHILIP J
IPC: B24B41/06
Filed: 1959-07-13
Abstract: 861,039. Couplings between relatively movable conducting parts; removing metal by electrolysis. HAMMOND MACHINERY BUILDERS Inc. July 13, 1959, No. 24068/59. Classes 38 (1) and 41. An apparatus for holding and positioning a workpiece 161 with respect to a. grinding wheel 15 in an electrolytic grinder comprises a frame 11, 13, a workpiece-engaging means, e.g. a collet 16 and holding device 17, rotatably supported on the frame, and an electrically conductive, annular element, e.g. a slip ring 137, resiliently urged at 141 into slidable contact with the collet 16, so that electric potential can be applied therefrom to the collet 16 and holder 17 in any position thereof with respect to the frame. The frame portion 11 is adjustable transversely of a fixed plate 21 and carries a cradle 34 angularly adjustable about a horizontal axis in the plane of the paper on releasing bolts 46, 47. The frame portion 13 is angularly adjustable through a maximum angle of, e.g., 30 degrees, about a vertical axis on the cradle 34, and carries through bearings 69, 70 the collet 16 which is rotatable about a vertical axis 155, the collet 16 supporting the adjustable workholding device'17 or. the work itself, Fig. 9 (not shown). Rotation of the collet 16 is by a shaft 78 and ring gear 76 on a sleeve 72 keyed to a housing 67 for the collet, axial movement of the collet 16 being ensured by its threaded engagement with a collar 117, rotational movement of which is prevented by manual operation of a spring-pressed pin, Fig. 7 (not shown). The collet comprises a sleeve 113 slotted at 114 which is flared at its top, as is the housing 67, whereby upward movement of the collet acts to open the bore 116 of the collet and downward movement to close it. A spring-urged collar 103 engages notches 99 in a skirt 97 secured to the housing 67 to locate the collet 16. Electrical connection to the collet 16 is via leads 143, 144 connected to the slip ring 137, and collar 117. A spring-urged cap 173, which engages the work or a post 157 on the holder 17, acts to eject the work, or holder 17, on raising the collet 16. The bearing 70 is vertically adjustable by a screw 88.

Abstract: 904,779. Radiation detectors. NIPPON ELECTRIC CO. Ltd. July 11, 1960, No. 24069/60. Class 40 (3). [Also in Groups XXXVI and XL (a)] A circuit for light amplification &c. comprises in series a radiation sensitive capacitor 1, Fig. 1, an electroluminescent element 2, and an inductor 3. The resonant frequency of the circuit is variable in response to light or other radiation incident on the capacitor 1; the output of electroluminescent element 2 in turn depends upon the resonant frequency of the circuit. A combined photo-sensitive mosaic and electroluminescent photo-image device, Fig. 3, comprises a glass base-plate 4 covered with a transparent conductive layer 5 carrying a layer 6 of electroluminescent material on which mosaic electrodes 7, which may be square, are formed, as by evaporating silver or aluminium on to the layer 6. An opaque layer 8, of, e.g., non- activated CdS, covers the electrodes 7 and layer 6. A photo-capacitive layer 9 is formed on layer 8 by mixing ZnS or CdS with resin, or by evaporating such material. Transparent electrodes 11, having the same shape and size as electrodes 7 and being covered with glass 10, are placed on layer 9 in register with electrodes 7 and are connected to inductors 12.

Abstract: 666,674. Concentration and purification of aqueous colloidal dispersions. DUNLOP RUBBER CO., Ltd., and PATON, F. J. Aug. 15, 1950 [Sept. 20, 1949], No. 24114/49. Class 41. A continuous process for concurrently concentrating and purifying an aqueous colloidal dispersion containing dissolved material comprises continuously supplying the dispersion to the space or spaces between a plurality of semi-permeable membranes spaced apart, maintaining an electric potential difference across the membranes to effect a separation of the dispersion into a colloidal-rich layer and a colloidal-impoverished layer, separately removing the layers in a continuous manner, and continuously removing dissolved substances from the aqueous colloidal dispersion between the membranes by dialysis. In the arrangement shown for concentrating natural rubber latex, rectangular frames 1 alternate with rectangular frames 2, adjacent frames being separated by regenerated cellulose 10. The frames are clamped together by means of nuts screwed on rods 4 which pass through holes in perforated lugs 3. The frames 1 with the adjacent degenerated cellulose sheets constitute water-receiving compartments, which alternate with compartments receiving rubber latex. Ammonia-preserved latex is supplied to the apparatus at each side through a header 16 and associated pipes and passages 9, and water containing dissolved ammonia at the same concentration as in the latex is supplied through a header 12 and pipes 13. Water is also supplied through the end pipes 13 to boxes 11 containing the electrodes across which an electric potential is applied. A rubber-enriched latex having a diminished content of dissolved solids is withdrawn through a header 18, and serum is withdrawn through a header 20. Water containing dissolved solids removed from the latex is withdrawn through a header 14,

Filed: 1959-07-16
Abstract: The invention comprises salts of testerone 3,5-disulphamylbenzoate of the general formula <FORM:0915129/IV (b)/1> wherein M represents an alkali metal or a quaternary ammonium salt forming group, and the 3,5-dinitrobenzoate of testosterone, and the preparation of the salts of the above general formula wherein M represents an alkali metal by esterifying testosterone with a functional derivative of 3,5-dinitrobenzoic acid to form testosterone 3,5-dinitrobenzoate, treating this compound with a mixture of alkali metal sulphite and bisulphite in the presence of a solvent e.g. dimethylformamide, to form the 3,5-disulphamylbenzoate of testosterone and isolating this compound in the form of a relatively water insoluble salt, and converting this salt into the required alkali metal salt by double decomposition.  The above process may be modified for the preparation of the sodium salt in that the potassium salt is first produced, the free sulphonic acid groups are then liberated e.g. by contact with an ion exchange resin, and are then neutralised with sodium hydroxide to form the sodium salt which is precipitated by the addition of a water-miscible solvent e.g. ethanol.  A quaternary ammonium salt may be added to form the insoluble salt in the above process e.g. benzyl dimethyl 2 - [2- (p-1,1,3,3-tetramethylbutyl - phenoxy) - ethoxy] - ethyl ammonium chloride.
