Title: Improvements in or relating to the production of hydrocarbons
IPC: C07C1/04
Filed: 1938-07-21
Abstract: 516,555. Gasifying solid fuel. UNDERWOOD, A. J: V. July 21, 1938, No. 21664. [Classes 55 (i) and 55 (ii)] In the synthesis of hydrocarbons from carbon monoxide and hydrogen obtained by gasifying carbonaceous material under pressure with steam wherein the synthesis takes place in a water-cooled reaction chamber with evolution of heat, low pressure steam produced by heating of the cooling water or contained in the products of reaction is used for the production of high pressure steam for use in the gasification step. The steam generated in a cooling coil 5 surrounding the reaction chamber 4 to which the reacting gases are supplied from a retort 3 wherein fuel is gasified with H.P. steam and oxygen, is supplied by pipe 16 to the intake of an injection thermocompressor 15 and from thence as H.P. steam is fed to the steam and oxygen inlet pipe 2 of the retort 3. In addition, or alternatively, the steam produced by passing the reaction products 7 through a heat exchanger, such as a boiler 9, is similarly boosted and used in the gasification step by passage to a similar compressor 12. The steam pressure in the reaction products may be raised prior to reaching the boiler 9. The H.P. steam from 12 may operate the compressor 15. In an example, L.P. steam of 7 atmospheres from the coil 5 is raised to 10 atmospheres by the compressor 15.

Title: Improvements in television and like receivers
IPC: H04N5/74
Filed: 1947-08-07
Abstract: 644,059. Television. SCOPHONY, Ltd., and WIKKENHAUSER, G. Aug. 7, 1947, No. 21704. [Class 40 (iii)] In a television &c. receiver in which a signal modulated cathode-ray beam varies the refractive index of an image screen to control a local light source which is transmitted through or reflected by the image screen on to a viewing screen, the light source has, in a plane perpendicular to the optical axis, a radial width (with respect to said axis) which is small in comparison with its length and is displaced from the axis by a distance greater than the width. The object of the invention, which is to arrange that the intensity of the light reaching the viewing screen 17 is proportional to the intensity of the cathode-ray scanning beam, is realized according to the invention by providing a light source comprising a narrow annular slit in a diaphragm 13 which is illuminated by suitable means (not shown), disposed to the right of the diaphragm, so that the light is caused to pass obliquely through the image screen 12, unrefracted light being arrested by means of an annular stop 15. With this arrangement the " gradient of the optical path " (as defined in Specification 514,155) will change by an amount which is proportional to the change in the refractive index of the image screen which, itself, is proportional to the intensity of the signal-modulated cathode-ray scanning beam.

Title: Improvements in and relating to the treatment of chocolate or other semi-liquid or plastic substances
IPC: B01F7/16
Filed: 1935-07-31
Abstract: 454,610. Mixing. BOGGILD, C. B. K., and JACOBSEN, M., 2, Kampmannsgade, Copenhagen, and AASTED, K. C. S., 3, Levkovej, Gentofte, both in Denmark. July 31, 1935, No. 217130. [Class 86] [See also Group VI] In a rapid process for conching chocolate, air is emulsified with the chocolate mass in an area of relatively high pressure, and is allowed to escape with unwanted water and undesired volatile constituents at an area of relative low pressure, where the emulsion is broken down. The chocolate mass is fed into a container 1 at an opening 9 where a propeller blade 31 forces it down into the funnel-like bottom 24. A secondary smaller propeller blade 32 is present to prevent a dead area. The propellers rotate on a central shaft 5 which also carries a disc 25 carrying pins 26 alternating with pins 27 on the fixed part 20. The pins 26 are carried round on the rapidly rotating disc 25 and cause the chocolate to be comminuted, and passed up the channel between the wall 19 and wall 1 of the container. The pins 27 are hollow and serve to introduce air into the swirling chocolate to form an emulsion and to raise the pressure at 23. The comminuted emulsion falls over the top edge of the wall 19 where the pressure is less than at the bottom, causing the emulsified air to escape, carrying with it water and undesired oils as vapour. The chocolate mass may be passed through a second chamber similar to the first, except that no air is admitted to the pins, to further break down the emulsion and remove the air, water and oils. Vanes 28 assist in forcing the mass up between the walls 19, 1. The space between the walls 1 and 2 is fitted with a temperature regulating medium.

Class 106 (2) A barometric type altimeter comprises a central support, a pair of diaphragm capsules mounted on the support for contraction and expansion in opposite directions for a given pressure change and a central pinion mounted on the support, a pair of gear sectors meshing with the pinion, a rock shaft for each of the sectors and a link pivotally connecting the movable wall of each capsule with its respective rock shaft to turn the rock shafts in opposite directions on a change of pressure acting on the capsules. A pair of capsules 24 are symmetrically mounted about the central support 23. Each capsule actuates through a linkage 29, 129 and rock shaft 32, 132, a gear sector 33, 133. The gear sectors work in opposite directions, Fig. 3, on a pinion 47 mounted on a shaft 48 which via a suitable gear train rotates a series of pointers over a dial. The action of the oppositely mounted capsules and gear sectors balances out static and dynamic loads to ensure freedom from errors. A series of pointers 60, 71, 77 move over a dial 84, Fig. 7, the pointer 60 completing ten revolutions for one revolution of pointer 71 and pointer 71 completing ten revolutions for one revolution of pointer 77, by means of the gear trains shown in exploded form in Fig. 7. The pointer 60 then indicates feet, the pointer 71 hundreds, and the pointer 77 thousands of feet. A knob 78 is provided to move the mechanism within the housing for setting in barometric pressure at sea level. A bimetal strip is incorporated in the linkage between the capsule and the gear sector in each case to compensate for temperature effects One such strip 134 is shown in Fig. 5 mounted on the rock shaft 132 between clamps 139 and 136.

Abstract: 1,020,574. Thermocouples. ENGLISH ELECTRIC CO. Ltd. June 15, 1962 [June 20, 1961], No. 22233/61. Heading G1N. [Also in Division H1] A thermo-couple 11 is mounted within a container 15 which is mounted within a second container 16 containing a quantity of a material, e.g. bismuth, 17 which undergoes a phase change at a known temperature within the working range of the thermocouple the remainder of the space being filled with an inert gas 18. The containers 15 and 16 may be of stainless steel or a small outer portion of the container 16 may be of stainless steel. The thermocouple wires may be mounted in magnesium oxide 14 to electrically insulate them. The arrangement is such that when the assembly is exposed to a high temperature the thermocouple temperature and hence its electrical output will rise steadily until the melting point of the bismuth is reached when the thermocouple temperature and its output, will remain constant until all the bismuth has melted. Since the melting point of bismuth is known a calibration point for the thermocouple is established. The arrangement is of use where the thermocouple is not able to be removed from an installation for checking e.g. when installed in a nuclear reactor.

Title: Improvements relating to fish filleting machines
IPC: A22C25/16
Filed: 1932-09-09
Abstract: 404,388. Dressing fish. ROWTON, J. L., 7, Devanha, Gardens, Aberdeen. Sept. 9, 1932, No. 22281. [Class 28 (ii).] In a machine for filleting or boning fish ; the fish are conveyed, e.g., by the conveyer described in Specification 372,455, tails foremost, under a pair of spaced disc knives 12, mounted on a swinging arm 14 which is so cam-controlled that the disc knives slit the fish on both sides of the smaller part or flat section only of the backbone, and are then raised to an inoperative position. The swinging of the arm 14 is effected by a roller-ended lever 21 secured to the shaft 16 and co-operating with a rotary cam 23. The knives 12 are flanked by a diverging spreader 26 which is pivoted at 27 to a counterweighted swinging arm 28 pivoted to a frame 30 at 29. The pivoting of the spreader 26 on its pivot 27 is controlled by a spring 34 and the swinging of the arm 28 is limited by an adjustable stop 35. The spreader 26 and a succeeding spreader 36, pivoted to the arm and limited in its swinging by an adjustable stop 37, are grooved on their undersides to accommodate the vertically disposed flat part of the backbone. The boning is completed by two plain or serrated disc knives 38 disposed at an angle to one another. In operation, the forward part of the spreader 26 enters the cut portion of the fish and spreads it. When the uncut thicker part of the fish meets the spreader, the fore end tips up, and is then brought level again by the bodily rising of the spreader with the arm 28 as the fish advances. As the fish leaves the spreader 26, the rear end is retained elevated as the fore end drops, and finally the arm 28 and the spreader fall bodily. The spreader 36 also rises and falls according to the position of the fish.

An outlet valve 22 for a pressurized enclosure such as an aircraft cabin is actuated through a lever 46 and link 43 by a flexible diaphragm 34 which is controlled by a valve 65 itself actuated by a flexible diaphragm 58 which is controlled by a unit (not shown) of known kind incorporating means for obtaining a constant cabin pressure up to a certain altitude and for maintaining a differential between cabin and atmospheric pressures above that altitude. The left-hand side of the diaphragm 34 is vented to the low pressure side of the outlet valve 22 and loaded by a spring 50 tending to close the outlet valve. The other side of the diaphragm 34 receives pressure air under control of the valve 65 from a chamber 62 which is connected by a conduit 15 to the delivery side of the cabin supercharger and contains a relief valve 81 for maintaining a, constant pressure. A bleed 40 interconnects the two sides of the diaphragm 34. The diaphragm 58 is subject on its righthand side to cabin pressure and to the load of a spring 70 and on its other side to a pressure obtained from a bleed 80 and governed by the control unit which is connected to a conduit 17. To operate the valve 22 manually, a handle 100 is depressed against a spring 100a to engage a clutch 23b whereby rotation of the handle operates the valve. A valve 85 actuated by a cam 94 relieves pressure to the right of the diaphragm 34 to facilitate manual closing of the valve 22.

Abstract: 1491502 Anaerobic digestion of water polluting waste material BIOMECHANICS Ltd 22 May 1975 [24 May 1974] 22390/75 Divided out of 1491501 Heading ClC A method of treating biodegradable waste material comprises the steps of submitting the waste material to anaerobic digestion to provide a treated liquid, subjecting the treated liquid to a thermal shock which is effected by a reduction in temperature of the treated liquid, which reduction in temperature is of such magnitude and is effected at such a rate of cooling that the gas-producing activity of anaerobic bacteria in the treated liquid is substantially inhibited, allowing the cooled treated liquid to settle, whereby bacteria in the cooled treated liquid sink in the liquid to leave a layer of sludge above which is a relatively clear liquid, and separately removing the sludge and the relatively clear liquid before the bacteria in the sludge regain sufficient gas producing activity to raise substantial quantities of solids in the sludge into the relatively clear liquid. The thermal shock preferably effects a reduction in temperature of the treated liquid of at least 8‹ C. in a period not exceeding ten minutes. The upper layer may be separated from the sludge by a region containing packing material which is capable of causing solids to be stripped from gas bubbles, such as Raschig rings made of a plastics material. A gas lift pump may be used to pass the treated liquid through the cooler. Effluents from factories operating the wheat starch/gluten/dextrose process, abbatoirs, confectionery factories, and creameries; single cell protein processes, wine making, domestic sewage, breweries, distilleries, meat processing, milk or dairy products, paper processing, sugar refining and textile processing are among the other sources of effluent mentioned.
