Patent GB-743257-A (GB)
Title: Improvements in synthesis of hydrocarbons
IPC: C07C1/04
Filed: 1952-12-17
Abstract: Hydrocarbons are produced by passing a gaseous mixture containing carbon monoxide, hydrogen and chlorine, bromine or iodine, or their hydrides, or substances yielding either under the conditions of synthesis, under superatmospheric pressure and at an elevated temperature over a bed of particles of an iron-base catalyst, characterized in that the effluent gas from the catalyst is brought into contact with a bed of particles of iron, an iron oxide or a conventional inert catalyst support, e.g. porous brick or tile on or in which iron is present, while maintaining these particles at a temperature which is below synthesis temperature to permit them to react with and to remove hydrogen halide from the effluent gas with formation of ferrous halide.  Suitable temperatures are 300-400 DEG C. and 200-250 DEG  C. respectively. According to one method, both the synthesis converter and the hydrogen halide stripper contain a fluidized bed of iron catalyst and the exit gases from the converter pass to the stripper worked at the lower temperature while catalyst is continuously circulated from the stripper to the converter where it loses part of its halide content as hydrogen halide, and catalyst from the converter is circulated to the stripper where it picks up hydrogen halide. In a modification, the catalyst from the stripper is passed to a regenerator where it is reduced with hydrogen and the reduced catalyst is recycled to the stripper, the gaseous effluent of hydrogen and hydrogen halide being sent to the synthesis converter. In another method, the exit gases from the converter are treated in the stripper until a considerable deposit of iron halide is formed on the iron catalyst whereupon the stripper is used as the converter and the converter used as stripper at a lower temperature until the iron halide formed therein is sufficient for the original order to be restored.  A further method comprises operating the converter with two strippers in parallel, one stripper being on stream to remove hydrogen halide and the other being subjected to regeneration with hydrogen at a higher temperature.  In examples synthesis gas together with some ethylene dichloride is passed through a 1 inch steel tube containing fluidized reduced magnetic ore at about 310-350 DEG  C. and the exit gases are passed through a similar tube containing the same catalyst at about 200 DEG  C. for removal of hydrogen chloride. Reference has been directed by the Comptroller to Specifications 684,130 and 692,158.

Title: Improvements in or relating to electrical signalling systems
IPC: H04J1/06
Filed: 1938-11-05
Abstract: 522,006. Automatic exchange systems. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., and CORNER, A. C. Nov. 5, 1938, No. 32148. [Class 40 iv)] In a system in which a common source of carrier current supplies two communicating stations, the source OSC is connected through separate amplifiers Al, A2 to opposite sides of a high-pass filter or band - elimination filter HPFI designed to pass one or both sidebands but not the carrier. Combined modulator-demodulators of dry rectifier type are used. The two stations may be respectively a main and a rural telephone exchange connected together by a single junction. In this case dialling and supervisory signals for an audio and a carrier channel may be sent in various specified ways by sending currents of audible and sub-audible frequencies and direct current over the loop, the phantom circuit and the separate legs. Where the phantom is not used for signalling it can be used for telegraphy. Two separate carrier channels may be provided and may employ respectively 'the loop and the phantom circuit for signalling. In another suggested arrangement the automatic rural office is between two manual offices which communicate with each other by means of a carrier channel which may be carried by the rural office switches or by a permanent high-frequency bye-pass.

Title: Recording and reproducing system.
IPC: H04N5/915
Filed: 1966-07-18
Abstract: 1,158,912. Video recording and play back. SONY CORP. 18 July, 1966 [17 July, 1965(2)], No. 32160/66. Heading G5R. In a video recording and playback arrangement, alternate fields or frames only are recorded in oblique tracks on tape 8 and during reproduction the played-back signal, in addition to being applied to an output circuit, is also re-recorded on a magnetic disc 9 from which it is reproduced during the following unrecorded field or frame period. During recording the video signals are applied via a frequency modulation circuit 21, recording amplifier 22 and switch 23 in the "R" position to recording and playback head 4. The head is rotated by motor 21 between guide members 7 around which tape 8 is directed by means of guide rollers set obliquely to the direction of tape travel. The arrangement is dimensioned so that the head contacts the tape during half its revolution and the speed of revolution is such that during this period one picture field is recorded, thus alternate fields only are recorded on the tape. During playback (switch 23 in position "P"), when the head 4 is reproducing the recorded field its output signal is applied via amplifier 24, switch gate 25, amplitude limiter 27 and demodulator circuit 30 to the output 31. In addition the output of the limiter is applied via amplifier 28 to a stationary recording head 11R and this records the field on a magnetic disc 9 which is also rotated by motor 1. At the end of field recorded on the tape a magnet 12a on the rotating arm 5 co-operates with pick-up winding 12b to generate a pulse which triggers a monostable multivibrator 26. This develops an output pulse which switches gate 25 to pass the field signal recorded on disc 9 and played back by playback head 11p to the limiter 27 and the output circuit 31. The signal recorded on the disc 9 is erased by head 13 after playback.

Abstract: 893,340. Hydraulic pit props. DOWTY MINING EQUIPMENT Ltd. Oct. 9, 1959 [Oct. 9, 1958], No. 32286/58. Class 20(2) [Also in Group XXIX] In a hydraulic prop having relief and release valves 85, 87 in a cap 71, the release valve 87 is actuated by a member 88 which is pivoted about a vertical axis 89. The prop comprises an upper cylinder 17, which is slidable in a lower cylinder, and an inner tube 18, which receives a ram on the lower cylinder, the upper cylinder being raised by a piston 80 reciprocated by a crank 72. An inlet valve 81 allows fluid to be drawn from a reservoir, located between the cylinder 17 and the tube 18, by the piston through tubes 78, 79 into a duct 83 which also communicates with the reservoir via the relief valve 85. The release valve 87 allows the pressure in the prop to fall until the valve 81 is opened by a spring 93 allowing a more rapid flow of liquid. During release, the piston 80 is in its upper position so that the valve 76 is held open by a pin 77 to connect the pressure space under the piston 80 with the duct 83. A chain &c. may be attached to the opening 90 in the member 88.

Radioactive liquid effluent obtained by the chemical decanning of irradiated nuclear fuel elements is decontaminated by forming in succession in the liquid precipitates of ferrous sulphide and hydroxide barium sulphate, and the ferrocyanide of a transition element of atomic number 21 to 29, and then separating the solid material from the decontaminated liquid. The liquid should be adjusted to a pH of 7 to 9. Magnesium-zirconium alloy cans are dissolved in sulphuric or nitric acid; when using nitric acid, nitrous compounds in the effluent liquid are first oxidized by adding potassium permanganate, and then sulphate ions are added before forming the precipitates.
