Patent GB-146110-A (GB)
Title: Improved manufacture of methane
IPC: C07C1/04
Filed: 1920-06-21
Abstract: Methane is prepared catalytically by passing a mixture of carbon monoxide and excess of hydrogen through a series of furnaces containing heated contact material, for example pumice carrying active nickel, the composition of the gases being adjusted at each passage, as for example by the addition of carbon monoxide, so that the amount of the latter does not exceed about one-fifth by volume of the hydrogen present, and the gases being freed from water vapour after each passage through a furnace.  Thus, between each pair of furnaces there is provided a condenser, and a connexion with a suitable measuring device for introducing the gases used containing originally a large excess of hydrogen.  In place of hydrogen, purified illuminating gas may be employed; and for carbon monoxide may be substituted a purified water gas.  The traces of hydrogen finally remaining in the gases may be removed by passage over cupric oxide, or the methane may be liquefied by cooling the gases.

Title: Hydrocarbon exploration
IPC: G01V9/00
Filed: 1976-04-26
Abstract: 1516281 Prospecting BARRINGER RESEARCH Ltd 26 April 1976 16918/76 Heading E1F [Also in Divisions G1 and H4] The presence of hydrocarbon seeps in the sea is determined by directing into the sea a beam of light radiation of sufficient intensity and of such wavelength that it produces light which emanates from subsurface zones of the sea and which is attributable to reflections and/or bioluminescence in the zones. As described, light from a pulsed laser 13 is reflected from a mirror 14 down from a low flying aircraft (Fig. 1, not shown) to layers of scattering (15) in the sea associated with increased microbiological activity and the presence of gas bubbles, reflected light being received by a telescope 17, a photomultiplier 18 and an oscilloscope 19 operating in synchronism with laser 13. The face of oscilloscope 19 may be photographed continuously to provide a permanent record of the intensity of observed surface reflections. A second trace can be displayed on the or another oscilloscope by splitting the output of telescope 17 using a dichroic mirror 20, Fig. 3 (not shown), one wavelength being that of laser 13 and the other being a longer wavelength representing bioluminescence. The oscilloscope display enables signals received from the sea surface (e.g. polluting oil slicks) to be differentiated from sub-surface scattering and bioluminescence, although other forms of recording (e.g. digital) could be employed. The laser wavelength is preferably in the blue or ultraviolet to achieve maximum sensitivity to scattering in the water and to stimulate bioluminescence in the suspended microorganisms.

Abstract: 543,437. Compensating meters for temperature errors. WALL, G., McCALLUM, G., and METROPOLITAN - VICKERS ELECTRICAL CO., Ltd. Nov. 28, 1940, No. 17007. [Class 37] An induction meter is provided with pieces 5, 6 of magnetic material of negative temperature coefficient of permeability carried by a non- magnetic support 4 so as to be located in close proximity to the outer edges of the faces of the current poles 2, 3 and separated from these edges by such a small air gap that errors due to increase in the resistance of the voltage coil are at least partially compensated. The support 4 is a rectangular loop of brass, copper, or resistance alloy and may have a cut in one of its shorter sides so that it does not itself form a closed circuit. A block 14 of magnetic alloy having a negative temperature coefficient of permeability is inserted centrally in the face of the voltage pole 1 in order to compensate for the reduction in the braking power of the permanent magnet on rise of temperature. This block may have a negative co-efficient effective over a different range from the alloy 5, 6. For further compensating errors due to increase in resistance of the voltage coil a winding 9 on the current poles is connected to a resistance 10 thermally associated with the voltage winding, for example by insertion between the winding and the core. The resistance 10 has a high temperature coefficient, for example it may be of iron or nickel wire. The magnetic alloy may be a ferro-nickel alloy as described in Specification 30297/10, [Class 37]. Specification 520,786 also is referred to.
Patent GB-644916-A (GB)
Title: A process for preparing chloral alcoholate or free chloral
IPC: C07C45/30
Filed: 1947-06-27
Abstract: A process for preparing chloral alcoholate or free chloral comprises contacting ethyl alcohol at a temperature not exceeding 35 DEG  C. with part of the chlorine required, and subsequently treating the heated reaction liquid obtained continuously in countercurrent with the rest of the chlorine required, whereby a prolonged contact between the hydrogen chloride formed and the unconverted ethyl alcohol, sufficient for the formation of substantial proportions of ethyl chloride is prevented.  The cold chlorination may be carried out batchwise or in counter-current. The chlorine supply may be adjusted in the hot process to produce chloral alcoholate or free chloral.  Pressure may be normal or otherwise, e.g. hydrogen chloride is more easily removed from the hot reaction zone by operating at reduced pressure.  A chlorination catalyst <PICT:0644916/IV (b)/1> may be present, e.g. ferric chloride.  In examples: (1) 96 per cent ethyl alcohol containing ferric chloride is passed into vessel 1 maintained at room temperature via tube 2 whilst chlorine is passed in through tube 3.  The reaction mixture is then passed through tube 5 into the top of heated reactor 6, further chlorine being led in at the bottom via tube 10. Hydrogen chloride escapes through the reflux condenser 7 and the reaction product collects in vessel 8.  Pure chloral is obtained from the latter by fractional distillation. Residual alcohol is collected in scrubber 12.  (2) A similar chlorination is carried out using a third reactor operating at an intermediate temperature between the hot and cold reactions, both free chloral and the alcoholate being obtained.  The Specification as open to inspection under Sect. 91 comprises also the production of dichloroacetaldehyde and acetals of di- and trichloroacetaldehyde. This subject-matter does not appear in the Specification as accepted.

Abstract: 833,861. Electrolytic cells. DU PONT DE NEMOURS & CO., E. I. May 30, 1958 [July 22, 1957], No. 17408/58. Class 41. An electrolytic cell, for electrolysis of hot liquids such as fused salts, comprises a cathode supported by one or more side arms movably mounted in the wall of the cell, the junctions between said side arms and the cell wall being sealed with a flexible dished metal seal disposed around said side arms, said seal having its concave side facing the cell wall and serving in operation to prevent leakage from the cell upon differential expansion of the cathode and the cell. The Figure shows a vertical section of a cell embodying the invention. A steel shell 1 is lined with refractory brick 2. A metal cathode cylinder 3 is disposed around a graphite anode 4. Electric power is conducted to cathode 3 by opposed cathode arms 5 which extend through the cell wall and are supported thereon by sliding blocks 6. A flexible dished metal seal 7 is integrally attached to the cathode arm 5 by welding at 8 to form a leak-proof joint and its outer edge is attached so as to be leak-proof, by welding at 9 to a metal member 10 which is part of the cell wall but electrically insulated from the steel shell 1. In operation, as the cell is heated the cathode 3 expands and arms 5 slide over blocks 6. Since there may be more resistance to the movement of the cathode arms in one direction than in the other, expansion stops may either be fitted to the arms as at 15 and 16 or installed externally as at 11 to stop the movement in one direction and ensure that further expansion will force movement in the other direction so that the cathode remains in uniform central alignment with the anode at the operating temperature. The dished seal 7 is sufficiently flexible to take up the movement of the cathode arm.

Abstract: 744,852. Rotary meters. KENT, Ltd., G. June 23 1954 [June 24, 1953], No. 17511/53. Glass 110(2)  A: mass-flow meter comprises a rotor rotated by the liquid being measured and means responsive to the density of the liquid to control the rotation of the rotor so that its rate of rotation is proportional to the mass flow of liquid. In Fig. 1 (Provisional) a rotor 2 is connected to an indicator 5 through gearing 3. Rotation of the rotor is damped by damping blades 6 which are secured between pairs of arms 7 pivoted at 8, Fig. 2 (Provisional), between flanges 9 on the rotor spindle 10. The reaction pressure on the blades is proportional to n<SP>2</SP>d, where n is the speed of rotation and d is the density of the liquid, tending to turn the blades 6 about their pivots 8 in a clockwise direction. The masses of the blade structures, supplemented by masses at 11 if necessary, give rise to central forces proportional to n<SP>2</SP> tending to turn the blades 6 in an anti-clockwise direction, hence the radial setting of the blades will depend on the density only. In a modification, Fig. 3 (Provisional), the damping blades 12 turn about pivots 13 perpendicular to their faces and their radial position is not affected by the density of the liquid but is controlled by another pair of density sensitive blades 15. In another form, Fig. 1, blades 18 of the rotor pivot about radial axes 19 and take up a setting proportional to the density of the liquid. The blades and masses may be suitably placed to eliminate the affects of gravity and acceleration.
