Abstract: 1,083,887. Valves. ROBERT BOSCH G.m.b.H. Oct. 26, 1964 [Nov. 29, 1963], No. 43482/64. Heading F2V. A single acting piston working in a cylinder 32 receives motive fluid from a pump 3 via line 5, chamber 6<SP>11</SP> and valve 27. When pilot valves 14, 19 are respectively opened and closed, fluid acts via lines 13, 20 above piston 11 to assist spring 12 in closing by-pass valve 10. Thus, when valve 27 is opened, cylinder 32 receives fluid at a pressure limited by relief valve 7. If valve 27 is closed the piston is locked in position and if valves 14, 19 are respectively closed and opened chamber 6<SP>1</SP> is vented and by-pass valve 10 opens. The return stroke of the piston occurs when valve 27 is opened. Valves 14, 19, 27 may be operated mechanically or electromagnet! - cally. In the modification of Fig. 3 (not shown), valve 27 is replaced by valve (43), the latter being controlled in a similar manner to valve 10 by pilot valves (50, 51).

Abstract: 1467995 Methane-rich gas BITUMINOUS COAL RESEARCH Inc 8 Oct 1974 [26 Oct 1973] 43550/74 Heading C5E Methane-rich pipe-line gas is made from a synthesis gas comprising hydrogen, methane, oxides of carbon and hydrogen sulphide and produced by the gasification of a carbonaceous feed by cooling, if the gas has a hydrogen : carbon monoxide molar ratio less than 1 : 1 introducing steam at a steam synthesis gas mol ratio of about 0À5 : 1, subjecting to a combined water gas shift a methanation reaction at 550-1050 F. (and preferably 500-2000 p.s.i.g.) to increase the hydrogen/carbon monoxide ratio of the gas and accomplish methanation of carbon monoxide and removing carbon dioxide and hydrogen sulphide from the product gas. As shown a hot char recycle stream 20 is contacted with steam and oxygen in a gasifier vessel 12 to produce a molten slag 22 and a gas which entrains and reacts with the pulverulent coal feed. The stream 16, e.g. at above 1600 F. and above 50 atmospheres, is separated into the char recycle stream 20 and a gaseous stream 24 which is cooled at 26 and subjected to the combined shift and methanation reaction at 30 after the addition of steam. The methane-rich gas 32 is cooled and in part recycled to the reactor 30 and in part further cooled at 38 and 40 and scrubbed at 44 to remove H 2 S and then at 48 to remove CO 2 . The scrubbed gas 52 can be reheated at 38 and 54 and subjected to catalytic methanation at 58, using a nickel catalyst preceded by a guard chamber of pelleted zinc oxide, to produce a pipe-line gas containing over 95% by volume of methane. The combined shift and methanation can be carried out in a fluidized bed having internal cooling coils or alternatively in a fixed bed or with catalyst suspended in liquid; a suitable catalyst comprises an oxide or sulphide of molybdenum with nickel or cobalt supported on alumina and promoted with potassium carbonate. The synthesis gas which is subjected to the combined shift and methanation reaction can be produced by the gasification of oil shale, heavy oil residues or tar instead of from coal.

Title: Improvements in and relating to processes for separating hydrocarbons
Inventor: MARCHANT ALAN
IPC: C07C7/17
Filed: 1960-12-29
Abstract: Cyclic and acyclic diolefins are separated from hydrocarbon mixtures by first dimerizing the cyclic diene and separating the dimer followed by reacting the acyclic diene with sulphur dioxide, removing the sulphone so formed and decomposing to recover the diene. Dimerization is effected at 40 DEG -130 DEG C. and up to 600 p.s.i.a. for 1/4 to 3 hours and the sulphone-forming step under similar conditions for 1-8 hours.  The sulphone is decomposed at 130 DEG -300 DEG C., e.g. by heating in a still fitted with a dephlegmator in which a hydrocarbon refluxes and allowing the sulphur dioxide and acyclic diene to escape as vapour as they are formed.  An antioxidant, e.g. 2,4-dimethyl-6-tert butylphenol, is preferably added during the processes.  Cyclopentadiene and isoprene and/or piperylene may be recovered by this method. Specification 934,529 is referred to.

Filed: 1970-09-23
Abstract: 1322789 Colour filters RCA CORPORATION 23 Sept 1970 [30 Sept 1969] 45310/70 Heading G2J [Also in Division H4] In a television system wherein striped filters are used to encode coloured images e.g. of a scene, or from a colour film on monochrome film and during playback the films strobed frame by frame for scanning with a vidicon to provide colour signals or subcarriers of different phase or frequencies and in luminance signal, the signal from the vidicon will contain components from two or more successive frames due to the lag inherent in such a pick-up, and misregistration of successive frame images will give colour flicker or loss, since corresponding subcarriers of successive images will be randomly displaced in phase. By using in alternate frames alternate ones of a pair of coplanar striped filters which are mirror images about a plane normal to the filter plane and to the intended direction of scanning, by arranging that the vidicon scanning is effected with a predetermined amplitude of spot wobble i.e. a predetermined number of scan lines are averaged, the effect of a retained signal from one frame may be cancelled by the signal from a succeeding frame. In a prefered embodiment Figs.2a and 2b, one filter comprises alternate cyan andtransparent strips 37, 38 at # R  = +17 degrees to a vertical line 39, and alternate yellow and transparent strips 35, 36 at # f  = - 50 degrees to the line 39, and the other filter is identical but rotated 180 degrees about the line 39. The minus red carriers from the cyan strips of both filters will be in phase every fourth line, and those from the yellow strips (minus blue) every two lines, whether or not the filters (or the encoded film frames produced by the filters) are relatively displaced in the optical path so that in this case cancellation of the unwanted carrier signal component is achieved using a spot wobble over four lines. Since this leads to a deterioration in vertical resolution including that of the luminance signal, the actual amplitude of the wobble is rendered dependent on the magnitude of the colour signals and derived from demodulation of the subcarriers, Fig. 3 (not shown).

The base region of a transistor is formed by the redistribution of impurities pre-deposited on a P-type body 12<SP>1</SP> into a layer 30 of N-type material substantially formed over the deposits. The base region comprises an active part 20 and a frame-shaped peripheral part 22, extending respectively partly and fully through the layer 30. In the embodiment described the collector region of a silicon transistor comprises a high resistivity P-type layer 12<SP>1</SP> epitaxially deposited on a low resistivity P-type substrate 10. A rectangular frame-shaped layer of phosphorus is deposited on the surface of the epitaxial layer 12<SP>1</SP>, and a less concentrated layer 20 of antimony is deposited to cover the centre of the frame, and to overlap slightly into the frame. A further epitaxial layer 26, 30 of high resistivity P-type silicon is then deposited on the layer 12<SP>1</SP>, and during a subsequent heating step the faster diffusing phosphorus diffuses through the layer 26, 30 to the upper surface thereof, to form a peripheral base region 22 isolating an emitter region 26. The base region 22 also diffuses down into the layer 12<SP>1</SP>. A low resistivity emitter portion 24 may be formed by a further boron-diffusion step. Suitable oxide masking is used during the manufacture. The process may also be applied to manufacture of an NPN transistor, which may form part of a microcircuit within a single wafer.
