Title: Improvements in thermistor bolometers
IPC: G01J5/20
Filed: 1960-06-23
Abstract: 881,575. Bolometers. FAIRWEATHER, H. G. C. (Barnes Engineering Co.) June 23, 1960, No. 22059/60. Class 37. A thermistor bolometer responsive to infrared radiation comprises a window 4 of material of high thermal conductivity of sufficient thickness to constitute a heat sink, and a thermistor flake 5 in heat conductive relation with said window. The window, which passes infra-red in a predetermined range, may be of vitreous fused alumina, quartz, or a semiconductor such as germanium or silicon. Terminal pins 3, connected to the thermistor 5 by wires 6, project through an insulating backing 2, the whole device being housed in a casing 1. If the window is electrically conductive a thin layer of insulating material is interposed between window and thermistor; this layer may be of material of low thermal conductivity, such as selenium or modified selenium glass, and of such thickness as to produce a predetermined time constant for the bolometer. The window may form a lens; Fig. 2 shows a hemispherical window 7 of germanium insulated by a layer 8 of selenium &c. from the thermistor 5. The lens may be less or more than a hemisphere. A second thermistor flake, not shown, masked from the radiation, is included in the device to provide temperature compensation.

Title: Improvements in or relating to the coating of metals with metals
IPC: C23C24/08
Filed: 1945-08-28
Abstract: Ferrous metal surfaces are coated with another metal to give a protective coating by sprinkling with the powdered coating metal, e.g., chromium, immersing in a finely divided refractory such as sand with which is mixed an alkali metal halide catalyst, introducing an alkaline earth metal, e.g., calcium, then sealing the container and heating to the alloying point of the two metals. Coating with chromium is described, in which the ferrous metal is covered with a viscous oil and rolled in chromium powder to give a layer about 1/8 inch thick; placed, together with a refractory such as sand with which is mixed the alkali metal halide, e.g., sodium chloride in amount 1/200th that of the sand, and calcium sufficient to combine with the oxygen and nitrogen in the vessel and with any oxides on the ferrous surface, in a vessel which is sealed and heated to 1,800 -1,900 degrees F., for twenty-four hours.  Two or more metals may be similarly used for coating, either in combination as powder, or separately, one being first deposited by, e.g., electroplating and the other(s) applied by the above process.

Title: Process for the manufacture of iodinin
Filed: 1971-04-19
Abstract: 1345026 Process for producing iodinin F HOFFMANN-LA ROCHE & CO AG 19 April 1971 [24 Feb 1970] 22436/71 Heading C2A The invention comprises a process for the manufacture of iodinin which process comprises selecting high iodinin-producing strains of the microorganism Brevibacterium iodinum by choosing for cultivation those microorganisms which display a deep purple colour in colony growth, cultivating these selected high iodinin producing strains under aerobic conditions in a liquid nutrient medium containing from 0À2 to 5À0% by weight of a complex nitrogenous product selected from hydrolysed seed meal, hydrolysed bean meal, hydrolysed milk products, hydrolysed meat protein and hydrolysed fish protein, from 1À0 to 10À0% by weight of carbohydrate and from 0À5 to 10À0 grams per litre of a surface-active agent, and at a pH in the range 5À0 to 9À5 until a substantial quantity of iodinin is produced, and separating the iodinin thus formed from the fermentation broth. In a preferred nutrient medium the surface-active agent is a non-ionic polyalkylene oxide silane emulsion, although organo-silicone polymeric surface-active agents may be employed. Fermentation is preferably effected at a temperature in the range 20 to 40 C. over a period of 2 to 12 days. The carbohydrate may be glucose and the complex nitrogenous product may be hydrolysed soya bean meal. Iodinin may be separated from the fermentation broth by removing the solids from the broth by centrifugation, dehydrating the resulting wet sludge by washing with a low molecular weight aliphatic water-soluble alcohol, drying the residue and extracting the iodinin from the separated broth solids with a non-reacting organic solvent. Such a solvent may be chloroform, methylene chloride or toluene.

Title: Improvements in or relating to the production of lipsticks and like cosmetic pencils
IPC: A45D40/16
Filed: 1963-06-05
Abstract: 1,039,085. Packaging lipsticks. EJECTORET S.A. June 5, 1963 [June 6, 1962; June 12, 1962; Nov. 14, 1962], No. 22445/63. Heading B8C. [Also in Division B5] A method of manufacturing lipsticks or like cosmetic sticks comprises filling a mould surrounded by a casing with a molten paste mass. A container 11 is carried between two endless chain conveyers 1a, 1b to a station 3 where empty casings 16 surrounding moulds are delivered to the container which then moves to station 4 on to a table 51 which moves up to raise the container from the conveyer, thus halting its movement, while molten paste is delivered into the casings through valve controlled discharge tubes 45. The table then moves down returning the container to the conveyer. The container now carrying casings filled with molten paste moves through a cooling chamber 5 when the paste solidifies, then to station 6 where plungers 65 move down to force caps 61 on to the casings, and finally to station 7 where the casings are ejected by the reverse movement of the conveyers.

Title: Self-sealing valve for inflatable pneumatic bladders or the like
IPC: F16K15/20
Filed: 1951-09-26
Abstract: 692,908. BrassiÞres. DAVENPORT, W. F., and SMITH, H. A. Sept. 26, 1951 [Oct. 4, 1950], No. 22534/51. Class 141. [Also in Group XXIX] In a brassiÞre with inflatable bust-pockets as described in Specification 674,598 the bladders have inflation valves consisting of a pair of layers 31, 32, Figs. 6, 10, of flexible but substantially non-elastic material e.g. a synthetic resin such as a vinyl material, secured together along spaced seams 34 formed by the application of heat and capable of separation by the interposition of a tube for inflation or deflation. The inner faces of the layers are highly polished so that when the layers are pressed together they seal the passage between the seams by molecular adhesion. The layers 31, 32 are secured between layers 25, 26 forming a bladder and preferably made of a material similar to that of the valve. In a modification, the valve is constituted by a layer 38, Figs. 12, 15, seamed at 39 to one layer 25 of a bladder and co-acting therewith. An opening 40 provides for the insertion of the inflating and deflating tube.

Filed: 1937-08-17
Abstract: 500,884. Sealing riveted joints. HOLLIS, H. H. Aug. 17, 1937, No. 22563. [Class 83 (iv)] The riveted seams of the sheets 2 forming the shell of a gasholder or like container are sealed against leakage by means of channel like members with side flanges welded to the sheets to enclose the seam and the rivets, said members being shaped to fit together at the junctions therebetween with mitred or curved welded joints or junction elements being provided shaped to fit the members at the junction and welded thereto. In one form, Fig. 1, channel members 3 with outwardly extending longitudinal flanges 4 are welded over the seams 1 along the edges 7 and where the various members 3 meet, the ends 5 are mitred and welded together at 6. In another form, Fig. 5, a through channel member 3b is cut away at the sides for the insertion of the ends 12 of cross members 3 and the joint welded at 13. In another form the ends of the cross members are mitred and welded down on to the through member. Fig. 6 shows a construction in which the joint between the members 3 is overlapped by a junction element 14 welded to the channel members around its edges. Alternatively, as shown in Fig. 11, the channel members 3 may be butted against a junction element 14 and the butted joints welded at 18. Similar construction, may be used for T-junctions between channel members. Specification 401,060, [Group XXIX], is referred to.

Title: Method of and apparatus for manufacturing a filtering material and filtering material thereby produced
IPC: A24D3/02
Filed: 1954-08-04
Abstract: 796,678. Making cigarette filter tips. MULLER, P. A. Aug. 4, 1954 [Aug. 4, 1953], No. 22682/54. Class 130. [Also in Group VIII] Filtering material for cigarette filter-tips is made by continuously perforating a single or multi-layer web of paper or like fibrous frangible material, parts of the web being displaced but not detached, whereby openings are formed therein having frayed edges. The web may be united to one or more other webs which may be perforated separately from, or jointly with, the first web, and the material may be rolled or folded to make the tips. The first, or carrier, web may be of paper such as tissue crepe, or other porous paper, of cellulose or cotton wadding, of inorganic fibres such as asbestos, or of parchment-type or other impregnated paper. The subsequent webs may comprise a felt-like web, such as cellulose or cotton wadding, or inorganic fibres such as asbestos. Multi-layer systems may be built up. As shown in Fig. 1, a carrier web 1 is supplied from a roll 3, and passes beneath a supply unit comprising a pair of rollers 6, 7 which are reciprocated across the width of the web 1, and lay thereon a layer of wadding which is supplied as a card fleece 9 on a conveyer 18, and passes between conveyer bands 10 and 11 to a funnel 19 before reaching the rolls 6 and 7. The relative speeds of the belts 10 and 11 and of the rolls 6 and 7 may be so adjusted that the fleece is first attenuated and then folded in zig-zag manner, as at 21. It is then laid in folds 22 on the web 1 and passes together therewith under a perforating roller 23. As shown in Fig. 5, the displaced portions of the webs are not removed, and the perforations have frayed edges. This may be done by using a perforating roller having wedge-shaped, obliquely projecting teeth, or conical prongs. The perforations may be of various shapes, and may be regularly or irregularly arranged. In the modified arrangement of Fig. 2, a web 31 is perforated by a roller 33, and passes beneath a felt-laying unit similar to that of Fig. 1, but provided with at least one perforating roller 7a. A further web 35, perforated by a roller 37, is then applied. As shown in Fig. 5, the filtering materials may comprise only two or more perforated carrier webs, e.g. of paper-like material, the long-stapled material web being omitted. Specification 15806/1910, [Class 31], is referred to.

Title: Engine control apparatus for controlling an internal combustion engine control device
IPC: F02D41/18
Filed: 1974-05-21
Abstract: 1432084 Automatic control of IC engines BENDIX CORP 21 May 1974 [25 May 1973 7 June 1973] 22725/74 Heading G3N [Also in Division F1] A fuel control system for an I.C. engine employs digital differential analyzers of which a first analyzer is stepped along a first characteristic in accordance with pulses derived from a first engine dependent parameter and then a second analyzer is stepped along a second characteristic in accordance with pulses derived from a second engine parameter to give a final pulse used to control the duration of fuel injection. The engine ignition advance can be controlled in a similar manner. The engine characteristics controlling fuel injection effectively form a three dimensional map as shown in Fig. 3a and the incremental dimensions are stored digitally in read only memories for reading out by the analyzers when they reach the engine operating point and can then provide an output of correct value for that instant of engine operation. The first analyzer DDA1 steps in response to a number of clockpulses representing the instantaneous engine speed over the characteristic 42, 44, 46, 48, 50 and subsequently the second analyzer DDA2 moves over the essentially logarithmic curve shown in response to clockpulses representing manifold pressure to provide a final pulse width output. A similar model relating manifold pressure, coolant temperature and pulse width is analyzed in a similar way by analyzers DDA3, 4 and the resulting pulse used to modify the length of the main pulse. Additionally a further pulse is derived from a starting enrichment characteristic which again modifies the injection pulse. The ignition advance of the engine is controlled in accordance with the three dimensional characteristic shown in Fig. 17 using a further pair of analyzers DDA6, 7. Since the ignition control is required at a different time in the cycle to the fuel control the electronic circuitry used can be time shared.

Title: Means for ensuring complete combustion of the coal used for heating steam boilers
IPC: F23H11/10
Filed: 1920-07-30
Abstract: 149,677. Burckhardt, R. W. Aug. 1, 1919, [Convention date]. Steam-generator furnaces; smoke-consuming.- In order to obtain complete combustion in a steam boiler furnace with a minimum amount of air, mixing-devices 8, 13 are arranged between a first boiler element and a second boiler element 3, the effect being that the unmixed and in part unburnt gases rising from the grate are cooled to a. safe temperature for passage through the mixing-devices where re-ignition and complete combustion take place. To facilitate mixture a portion of the air is supplied above the gases as at 12. The mixing-device 8 is of the kind covered by Specification 149,676. The application of the invention to other forms of water-tube boilers is described. Specifications 12340/00, 27024/05, and 6976/10 are also referred to.
Patent GB-620417-A (GB)
Title: Improvements in or relating to edible chocolate products
IPC: A23G1/04
Filed: 1946-07-31
Abstract: Moisture is applied to the surface of sweetened chocolate to dissolve out some sugar, thereby forming a syrup film which is subsequently dried to form a skin of crystalline sugar.  The chocolate may comprise a coating on an edible centre.  After mixing and grinding, the chocolate mix is worked in a melangeur just long enough to give a suitable consistency while leaving a multiplicity of surfaces of the non-fat constituents in a fat-bare condition to give sufficient internal friction to make the chocolate self-sustaining at high temperatures.  Temporary fluidity, sufficient to facilitate enrobing, may be provided by adding a small amount of water, say 2 to 3 per cent, before mixing.  Skim milk powder may be added before the first mixing, but if mixing, grinding and working are not continuous, the addition is preferably withheld until just before the final working. In the latter case, spray-dried whole milk powder can also be used. The fat content of the mix is limited to not more than about 35 per cent.  The moisture required for producing the sugar skin can be applied, either while the chocolate is still plastic or after it has set, by dipping the product in a water bath, by spraying it with water or, preferably, by subjecting it to an atmosphere saturated with moisture.  In the latter case, the products may be placed on a stationary mesh within a chamber in which the air is maintained substantially saturated with moisture at a temperature of about 98 DEG F. for 2 to 7 minutes. According to one method, sweet-meat centres carried on a mesh conveyor are given a chocolate coating in an enrobing machine and are transferred to another conveyer having a flat, smooth surface which carries them to a cooling tunnel, moisture being applied before the latter is reached.  In addition, the bottoms of the pieces are moistened before they are picked up by the second conveyer, or water can be applied to the latter before it receives the pieces, as by a water bath, spray or wiper.

Abstract: 205,472. Compagnie pour la Fabrication des Compteurs et Materiel d' Usines Ó Gaz, (Assignees of Soc. des Etablissements Ducretet). Oct. 14, 1922, [Convention date]. Thermionic amplifiers and detectors.-Noises due to using rectified alternating current to supply the plates, and alternating current for heating the filaments, are eliminated by introducing into the plate circuits a second source of alternating current of the same frequency as the supply. A differential arrangement of two valves which causes the undesired currents to be balanced out may be used in combination with this method. As shown, the filaments of valves 1, 1<a> are fed from a transformer 6 and the plates are fed with rectified currents from the points 5, 5. Feed noises are partially eliminated by the additional winding 10 on transformer 6 in the plate circuits. The input transformer 17 has two secondary windings so arranged that when signal currents make the grid 3 positive they make the grid 3<a> negative. The output transformer has two primaries 20, 20a arranged so that currents in the same direction through them produce no effect in the secondary 21. Fluctuations due to feed' currents do not therefore affect the telephone 9. The effects of signals on the other hand are added in the secondary 21 since they are 180‹ apart in phase. In the case of a high-frequency system in which' the last valve is a detector the final output transformer has an additional primary winding through which flows only the plate current of one of the preceding high-frequency valves.
