Patent GB-425113-A (GB)
Abstract: 425,113. Cables. OKONITE-CALLENDER CABLE CO., Inc., Paterson, New Jersey, U.S.A. Sept. 4, 1933, No. 24451. Convention date, Sept. 2, 1932. [Class 36] In a cable installation of the kind wherein the cable is enclosed in a cable pipe filled with oil or other insulating fluid under pressure, to prevent excessive loss of oil in event of a leak in the cable pipe, the different sections of the pipe are connected together by stop or semi-stop joints and each joint is by-passed by a pipe containing a pair of automatic shut-off valves ; the arrangements being such that all the valves are normally open and permit flow of oil in both directions through the cable pipe, whilst in event of a leak in one of the sections the appropriate valves shut and isolate this section from the remainder of the installation. In the installation shown, the cable pipe 1 is divided into sections 24-27 by stop joints 4-6, and its oil filling is maintained under pressure by pumps 3 which are connected between the ends of the pipe and reservoirs 2. Automatic shut-off valves 22, 28 are provided at the ends of the pipe, and the joints 4-6 are byepassed by pipes 11, 15, 19 containing automatic shut-off valves 9, 10, 13, 14, 17, 18, which are arranged in pairs. The shut-off valves permit a predetermined maximum flow of fluid past them in both directions and a fall of pressure on one side of a valve, resulting in an abnormal flow of fluid past the valve, causes the valve to shut. Thus the valves 9, 14 would shut and isolate the section 26 of the cable pipe if this section developed a leak of such a magnitude as to cause an abnormal flow of oil past these valves. Pressure gauges 28 may be provided in the byepasses to indicate a leaky section of the cable pipe.

IPC: H03K17/693
Filed: 1960-12-14
Abstract: 1,013,921. Selection circuits. POSTMASTER GENERAL. Dec. 13, 1961 [Dec. 14, 1960], No. 43092/60. Heading H4K. A circuit for selecting with a given order of priority one circuit from a number of marked circuits comprises a number of trigger circuits 1, 2 . . . N each having input terminals A1, A2 . . . AN, output terminals X1, X2 . . . XN, operate terminals B1, B2 . . . BN and transfer terminals Y1, Y2 . . . YN, each transfer terminal being connected to the succeeding operate terminal, each trigger unit being arranged to signal to its output, on receipt of an operate signal and an input signal, but to signal to the transfer output on receipt of an operate signal but no input signal. As shown, with no input to A1 and with OS back, the former condition cuts off T1 and the latter cuts off T3 and T4 which in turn cuts off T2. T5 is thus conducting to apply earth to Y1. On one or more inputs being applied to A1, A2 . . . start lead SL is energized to cause OS to open. This partially enables T3, and switches on T4. If A1 is energized T1 switches on to keep T2 cut off and also further enables T3 which then applies an output to X1 signifying selection of the associated circuit. With T2 off T5 maintains earth on terminal Y1. If A1 is not energized however, T1 does not conduct so that T3 is not enabled and no output is applied to X1. However T4, conducting, can now cause T2 to conduct (T1 being off) thereby cutting off T5 to apply a negative signal to Y1, which becomes an operate signal for trigger circuit 2 which then operates in a similar manner. Thus circuits marked over leads A1 . . . AN are selected in order of priority.

Abstract: 1,153,055. Photographic processes. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Sept.27, 1966 [Sept. 30, 1965], No.43116/66. Heading G2C. [Also in Division H1] In a method of fixing a first powder to a support using a photo-sensitized binder, which first powder is absorbent to the radiation to which the binder is sensitive, a solution of the photo-sensitive binder containing a second powder, which does not absorb the radiation and which is chemically convertible to the first powder by a process which does not produce gaseous products, is spread on the support, dried, exposed to the radiation so that selected areas are more easily removed by a solvent than other areas, those more soluble areas removed with the solvent and the second powder chemically converted into the first powder. This method may be used to apply the guard bands to the screen of an indexing-type colour television tube. The first powder which provides the guard bands may comprise any one or mixture of the oxides of Ni, Cu, Co, Me, Fe, Pb, Cr or any one or mixture of the sulphides of Ni, Cu, Pb. The second powder, which may comprise any of the oxalates of Ni, Co, Mn, the carbonates at basic carbonates of Ni, Cu, Co, Mn, Pb, Fe or the phosphates of Ni, Cu, Co, Fe, Pb, Cr, may be converted into the first powder by either chemical oxidation using, for example, potassium permanganate or rinsing with sulphide solution. The radiation preferably renders the photo-sensitized binder e.g. bi-chromated polyvinyl alcohol insoluble in the solvent and the chemical conversion preferably is effected after the soluble binder has been removed.
