IPC: H02K3/14
Filed: 1971-04-19
Abstract: 1343315 Coils for dynamo-electric machines WESTINGHOUSE ELECTRIC CORP 19 April 1971 [25 March 1970] 24187/71 Heading H2A In a stranded conductor for a dynamo-electric machine the strands are disposed in two side-byside stacks and are transposed between the stacks, the cross-overs between the stacks being non-uniformly spaced so that three untransposed sections are formed in the slot portion of the conductor and unbalanced strand voltages are produced in the slot portion to compensate strand voltages produced in the end portions of the conductor, the total angle of transposition of each strand being between 450 and 540 degrees. The end portions are not transposed. As shown for 540 degree transposition the strands are inverted at opposite ends of the slot portion of the conductor and the conductor includes untransposed sections 15, 14, 16 at positions corresponding respectively to transpositions of 90, 270 and 450 degrees. The length of portion 14 equals the sum of the lengths of portions 15 and 16. In a modification, Figs. 7-10 (not shown), the total angle of transposition is 480 degrees and untransposed sections are provided at positions corresponding to transpositions of 60, 240 and 420 degrees.

Title: Improvements in pipe lines for loading and unloading ships and other vessels
Inventor: HARTLEY ARTHUR CLIFFORD
IPC: B63B22/02
Filed: 1956-08-08
Abstract: 808,675. Handling liquid cargoes. HARTLEY PATENTS Ltd., C. July 26, 1957 [Aug. 8, 1956], No. 24286/56. Class 78 (4). A pipe line 1 on the bed of the sea or other body of water is connected to a ship 11 by means carried on a structure 5 hinged at its lower end and maintained in an upright position by one or more buoyancy tanks 8. In the construction illustrated the structure 5 normally rests horizontally on the bed of the sea and is raised when water is forced out of the tanks 8 through vents 9 by air admitted through a hose 17 terminating in a suitably valved float 18. The float 18 may provide for both quick and gradual releaes of the air in the chamber 18 to lower the structure 5. Alternatively the hose 17 may lead to a shore installation or the tank 8 may be permanently buoyant or may be capable of connection with a further tank on the structure containing compressed air. The structure 5 is preferably formed by four rigid conduits such as 4a, 4b, reinforced by a frame 6 and connected by flexible conduits 3 to the pipe line 1. The lower end of the structure 5 is connected to the bed of the sea by chains 15 arranged so that the structure pivots about a horizontal axis which may, however, rock slightly. The structure may be biased by weights to ensure that it falls in the right direction when the chamber 8 is flooded and a safety chain may be connected between the structure and the sea bed to prevent the structure falling in the opposite direction. The ends of flexible conduits 10 serving to connect the rigid conduits 4a, 4b to the ship may be joined together and connected to a buoyed hoisting cable.

Title: Improvements relating to the measurement of circular diochrism
IPC: G01J4/04
Filed: 1967-05-26
Abstract: 1,129,940. Measuring circular dichroism photo-electrically. CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE. May 26, 1967 [May 26, 1966], No.24649/67. Heading G1A. [Also in Division H4 ] Apparatus for measuring circular dichroism comprises means for producing a beam of monochromatic linearly polarized light, an attenuator for varying the intensity of the beam, a birefringence photo-elastic modulator producing from the beam a further beam having a polarization varying from left elliptical to right elliptical at a predetermined frequency a sample holder in the further beam and a photo-electric system responsive to variations of the light passing through the sample at the predetermined frequency to control the attenuator. Light from a deuterium or xenon lamp 1 is passed through a variable monochromator 4 to a unit 7, (see Division H4) which produces a linearly polarized beam of intensity oscillating sinusoidally between intensities #o (1  y sin x) where y and x are adjustable parameters. The polarization of the light from unit 7 is modulated by a modulator 8 (see Division H4) so that it varies between left and right elliptically polarized in synchronism with the intensity variations produced by unit 7. The light from the modulator 8 passes through the sample 10 to a photo-multiplier 11 and the component in the output thereof at the modulation frequency is selectively amplified by an amplifier 12 and applied to the unit 7 to reduce the component substantially to zero. It can be shown that the feedback current to achieve this is a measure of the circular dichroism of the sample 10 and its value is detected by a synchronous demodulator 13 and recorded. The ellipticity maxima of the output of modulator 8 are maintained constant with wavelength by a programmed control circuit 16 synchronized with the monochromator drive motor 9. Chromatism of the unit 7 is compensated by a correction circuit also synchronized with the motor 9.

Title: Improvements in or relating to the production of valuable liquid hydrocarbons by thedestructive hydrogenation of solid carbonaceous materials
IPC: C10G1/00
Filed: 1934-08-28
Abstract: Solid carbonaceous materials prior to their destructive hydrogenation in presence of acidic substances are freed from ash by a physical treatment, e.g. by froth flotation, settling, &c.  A bituminous coal containing 8 per cent ash is finely ground and then stirred with a calcium chloride solution of 1,35 specific gravity, whereupon the ash sinks to the bottom while the coal floats on the top.  The coal is skimmed off, freed from calcium chloride solution by spraying with water and impregnated (1) with sulphuric acid of 50 per cent strength so that 8 gs. anhydrous sulphuric acid are present per kg. coal; (2) with ammonium molybdate solution containing 0,1 per cent isopropylnaphthalene sulphonic acid.  The coal thus prepared, dried and made into a paste with oil, is destructively hydrogenated at 460 DEG  C. and 200 atms. pressure and 92 per cent of the carbon is converted into liquid products.  Examples of acidic substances are given and include organic and inorganic acids, acid salts, neutral salts which decompose under the reaction conditions to set free acids such as organic halogen compounds and metalloid compounds with halogens.  Wetting-agents and catalysts may be added.

Abstract: 491,908. Retractive switches. JAMES, J. P. Sept. 13, 1937, No. 24843. [Class 38 (v)] [Also in Group XXV] A lock is released by the energization of a number of solenoids under the control of three or more manually operated switches or switch contacts actuated in the correct predetermined sequence. The manually operated switches or switch contacts may be embodied in a multiple switch, Fig. 5. The fixed contacts of these switches are replaced by contact elements similar to 153 which are mounted in, but insulated from the ring 135. A rotatable contact arm 136, operated by a knob 140, makes contact with any of the contacts 153 by axial movement of the spindle 139 against the spring 142, which movement also brings the end 143 of the spindle into contact with the metallic closure disc 144 of the casing 137 to complete the circuit. The casing 137 is provided on its exterior with a scale to enable the user to locate the contacts similar to 153. A conducting ring 135 is used to energize a trip coil which breaks a hold-on circuit and prevents release of the lock by any other than the correct combination.

Title: Purification of hydrofluoric acid
IPC: C01B7/19
Filed: 1922-09-18
Abstract: Hydrofluoric acid is prepared free from silicon compounds by passing the gases evolved on treating fluorspar containing silica with sulphuric acid into a scrubber containing potassium sulphate. A solution of potassium sulphate is preferably employed and it is kept hot to avoid condensation of the hydrofluoric acid.  The precipitate of potassium silicofluoride which is produced is removed periodically and the residual acid liquor containing sulphuric acid is utilized in the decomposition of more fluorspar.  Potassium sulphate may be recovered from the precipitate of potassium silicofluoride by decomposing with sulphuric acid, distilling off the hydrofluosilicic acid, evaporating and leaching the residue in order to separate the potassium sulphate.ALSO:Potassium silicofluoride is obtained in the preparation of pure hydrofluoric acid by passing the gases evolved on treating fluorspar containing silica with sulphuric acid into a scrubber containing potassium sulphate preferably in the form of a solution.  The silicon fluoride and hydrofluoric acid present react to form potassium silicofluoride.
