Abstract: 1374972 Current collectors for electric railways MORGANITE CARBON Ltd 25 Nov 1971 [26 Aug 1970] 41035/70 Heading B7L A current collector for a railway overhead power conductor comprises a holder 12 with a carbon member 10, Fig. 1A, having a channel therein containing a rupturable tube 11 which will be broken or ruptured on occurrence of breakage or excessive wear of the member 10, the tube 11 being connected in use so that rupture thereof will cause loss of fluid pressure, this being utilized to effect retraction of the collector from the conductor. The carbon member 10 may be a single elongated piece of carbon either straight or curved, or may be made up from short length pieces of carbon arranged end to end in a holder formed with chordwise flats set so that with the carbon pieces in position the equivalent of a curved single length piece is obtained. In this case the tube 11 extends through aligned channels in the short carbon pieces. The tube 11 may be of silicone rubber or polytetrafluoroethylene and is preferably bonded to the member 10 by an adhesive. Alternatively the tube may be formed integrally with the member 10 by coating a throughbore with a material to render it fluid-tight. The collector may be raised by pressure air under the action of a motor 14, Fig. 4, preferably by use of a pantograph. Pressure air is fed by way of a control valve 15 and throttle 18 to a chamber 20 of a valve casing 21 containing a piston valve 22, and also to the tube 11. Under normal conditions the valve 22 will move to the right in Fig. 4 against the action of a spring 25 allowing air from a branch line 23 to actuate the motor 14 by way of a supply line 24. If the tube 11 is ruptured, the valve 22 will return to the position shown connecting the line 24 with an exhaust line 26, thus lowering the collector.

Abstract: 1,206,957. Testing cable insulation. OKONITE CO. Sept.8, 1967. No.41236/67. Heading G1U. In a modification of the method of inspecting cable described in (Specification 1, 204, 704) in which the cable is periodically irradiated by short bursts of highly penetrating radiation, while a stressing voltage less than the corona inception level is applied between an internal cable conductor and an electrode external of the cable insulation, so as to cause bursts of corona discharge in any discontinuities in the cable, which bursts are detected, the bursts of radiation are controlled by a pulsing means energized by the stressing voltage source. In one arrangement Fig. 1 (not shown), the bursts of radiation are produced by an X-ray tube where grid is periodically energized by a pulse generating circuit which is energized from the stressing voltage source. In an alternative arrangement Fig. 2, a gamma radiation source 54 is used, and the radiation from it is alternately transmitted and obscured by an apertured shutter 60 driven by a motor energized from the stressing voltage source. The system may be operated such that the cable 48 is moved relative to the radiation source at 200 ft. per minute, and the radiation source is pulsed at 60 c/s, to provide three radiation pulses for each two inches of cable. Each pulse is about nine milli-seconds duration. The stressing voltage may be about 300 volts D.C. or may be A.C. with a peak to peak value about 50% above the rated value of the cable.

Title: Process for preparing a werner complex solution and use thereof in clathration processes
Inventor: SCHAEFFER WILLIAM DONALD
IPC: C07C7/152
Filed: 1964-10-12
Abstract: In a selective clathration process for the separation of mixtures of organic compounds, the feed mixture is contacted with a solution of a Werner complex prepared by mixing water, a water-soluble nitrogen base, a hydroxide or carbonate of a metal of atomic number above 12, and an ammonium salt of a suitable anion, and then adding a Werner amine (see Division C2). Specified feeds are xylene mixtures such as those containing o-, m- and p-xylene and ethylbenzene.ALSO:A solution of a Werner complex is prepared by reacting water, a water-soluble nitrogen base (especially an alkanolamine), a hydroxide or carbonate of a metal of atomic number above 12, and a stoichiometric excess (with respect to the metal hydroxide or carbonate) of an ammonium (including organic ammonium) salt having an anion which forms a soluble complexing salt with the metal hydroxide or carbonate, this complexing salt itself being capable of forming relatively water-insoluble Werner complexes with Werner amines; and adding to this solution a Werner amine to form the Werner complex in solution; the nitrogen base used having a dissociation constant greater than 10-6 and in any case greater than that of the Werner amine.  Suitable Werner amines include pyridines, triazoles, quinolines, isoquinolines, pyrimidines, pyrazines and pyridazines; and substituted benzylamines; metals specified or exemplified are Mn, Fe, Co, Ni, Cu, Hg, Cd, Ag, Cr, Ti and Zn.  The anion in the Werner complex salt may be e.g. CNS-, NCS-, N3-, CNO-, NCO-, CN-, SO42-, NO3-, NO2-, Cl-, Br-, I-, PO43-, formate or acetate.  Preferably, the base of the ammonium salt used is the same nitrogen base as is also used.  In a preferred procedure, aqueous ammonium thiocyanate is mixed with an excess of an alkanolamine, less than a stoichiometric quantity (with respect to the NH4SCN) of Ni(OH)2 or NiCO3 is added, and 4-methylpyridine is added to provide a solution of [Ni-(4-methylpyridine)4(SCN)2].  The solutions of Werner complexes are used to separate mixtures of organic compounds by a clathration procedure.

Filed: 1976-10-12
Abstract: 1506087 Television NIPPON VICTOR KK 12 Oct 1976 [17 Oct 1975 30 Jan 1976] 42366/76 Heading H4F Beat frequencies and ensuing moire disturbance are avoided on a magnetic video tape reproduction system by employing a phase shift of the colour subcarrier during recording. By this process successive tracks 35, Fig. 2, may be recorded adjacent one another without intervening gaps. The phase shift is performed by separating the chrominance component from a video signal and advancing its phase by 90 degrees between lines during a first period and retarding its phase by 90 degrees between lines during a second period and so on. The luminance component is frequency modulated before recording and the chrominance component is frequency converted prior to phase adjustment as described above, affording a reduction in band width requirement. Further track separation is achieved by the use of recording heads having offset azimuth. Cross talk generated by mistracking of the read heads is avoided by employing a one line delay and combining the chrominance signals from adjacent lines whereby the resulting phase relationship leads to elimination of disturbance.
