Title: Method of and means for producing illumination effects
IPC: A21B1/00
Filed: 1937-11-02
Abstract: 504,761. Electric radiators ; lamps ; lantern screens. BERRY, G. J., and PAINTON, C. A. Nov. 2, 1937, Nos. 29991 and 34642. [Classes 39 (iii) and 75 (iv)] An electric panel radiator 1 with a spaced backing screen 2, with or without further spaced screens, such as the surface of the alcove 3 housing the radiator, is provided with illuminating means arranged to project gradually changing coloured light onto substantially the whole of the surface of the screen or screens. The illuminating means may comprise a rotating cylinder 4 of translucent material coloured in longitudinal stripes, suitable colours being those of the visible spectrum surrounding a lamp 8. The illuminating device is arranged within the hollow of the surround 5 of the alcove, the open underside of which is closed by a sheet of glass 7. The arrows show the screens and the base of the radiator illuminated by three beams of differently coloured light. The cylinder is borne by pairs of rollers 9, 10, Fig. 3, at its ends, one of the former of which is driven by an electric motor housed in a chamber 11. A removable bracket 14 carries a socket 15 for the lamp and a reflector 16. In another form of the illuminating means, the lamp and reflector are enclosed by three translucent cylinders of differing diameters arranged side by side, each of the cylinders being providedwith a longitudinal red, yellow, and a blue band. The cylinders are carried by sets of rollers on a pair of shafts on each side thereof, and the different rates of rotation of the cylinders produces a number of colour combinations on the illuminated parts. Similar results are produced by replacing the cylinders with discs 29, 30, 31, Fig. 6, of differing diameter, each being divided into red, yellow and blue sectors. The peripheries of the discs contact with another and one of them also with a driving roller 32. Lamps 33 are arranged behind the discs. Rotating cylinders may also be arranged in the sides or bottom of the alcove ; the surround at the top of the latter may have a transparent or translucent upper surface to enable an ornament thereon to be similarly subjected to changing coloured light. Light of " warm " and " cold " tone may be projected on the illuminated surfaces in winter and summer respectively, the changeover being thermostatically controlled. The invention may be applied to the radiators described in Specifications 445,853 and 447,437.

Filed: 1920-10-23
Abstract: 174,694. Webb, J. F. Oct. 23; 1920. Fluid-pressure.-A pparatus for applying the air brakes of a train when a predetermined speed is exceeded comprises a valve adapted to be operated by a centrifugal governor to cut off the train-pipe from the air supply and to vent it through an audible signal, the valve returning b y gravity to re-establish the train-pipe connections and so release the brake when the speed has been reduced. The spindle 4 driven from the axle of the engine or other part, has a pin 16 on which are pivoted the balls 17 upon which rest at 18 projections 14 on a sleeve 12 slotted at 15 for the pin 16 by which the sleeve, is rotated. The sleeve 12 supports through a bearing 13. the weight 21 guided by the fixed lugs 20. The weight 21 is in two parts bolted together at 22 and is varied according to the limiting speed desired. It is connected to a valve stem 29 by lugs 25 engaging projections 26, 27. The stem 29 has guide members 30 and carries pistons 32, 33, 34, controlling ports 39, 45, 41 communicating by way of annular chambers 38, 40, 46 and connections 37, 42, 47 respectively with the driver's valve, the atmosphere through a pressure-retaining valve and an audible signal, and the train-pipe. In running conditions therefore air is supplied from the main reservoir to the train-pipe through the driver's valve and the connections 37, 39, 45, 47. If the speed limit is exceeded the pistons 32, 33, 34 are lifted so that the train-pipe is cut off from the driver's valve and is vented to the atmosphere by the ports 45, 41, the orifice 42, the pressure-retaining valve and the audible signal, thus applying the brakes.

Abstract: 1443878 H 2 SO 4  processing METALLGESELLSCHAFT AG 5 July 1974 [7 Aug 1973] 30035/74 Heading C1A Spent aqueous sulphuric acid liquor which contains substantially inorganic impurities and up to 40% by weight of H 2 SO 4 , is processed by treating with hot H 2 SO 4 -decomposition gases so that water is evaporated from the liquor by direct heat exchange to give an H 2 SO 4  content of not more than 65% by weight, and forming water-vapour laden exhaust gases of temperature 80-100 C.; the hot H 2 SO 4 -decomposition gases are generated by heating the concentrated H 2 SO 4  liquor to 800-1100 C. in a fluidized bed using oxygen-enriched air and a fuel. In the Figure, spent H 2 SO 4  liquor is introduced via 5 into a spray evaporator 3 where it is contacted countercurrently with H 2 SO 4 -decomposition gases introduced via 6. The pre-concentrated liquor formed flows via 7 to a pump receiver 8, and from there via 9 to a second spray-evaporator 4, where it is conducted co-currently with H 2 SO 4 -decomposition gases introduced via 10 from hot cyclone 2. From 4, the spent H 2 SO 4  liquor (now containing up to 65% by weight of H 2 SO 4 ) is passed via 11 to a second pump receiver 12, and from thence via 13 to charging lances by which it is introduced into the fluidized bed of reactor 1. O 2 -enriched air is introduced into 1 via conduit 14, while fuel (e.g. fuel oil, fuel gas, FeS 2 , sulphur) is introduced via lance 15. Dust from the H 2 SO 4 -decomposition gases from 1 is collected in the hot cyclone 2, while the gases enter the spray evaporator 4 via conduit 10. The hot, moist exhaust gases from the process leave the spray evaporator B via conduit 17.

Title: Improvements relating to the production of citric acid
IPC: C12P7/48
Filed: 1926-11-27
Abstract: 287,604. Distillers Co., Ltd., and Peake, A. M. Nov. 27, 1926. Citric acid.-Citric acid is obtained by the treatment of suitable pectinous or similar materials with enzymes existing in citrus fruits. The enzymes which occur chiefly in the pith or inner layer of the rind of the fruits are extracted. for example by a weak solution of an organic acid. or the pith itself is used, the essential oil-containing layer being first removed. The raw material to be treated may be the pulp of the fruit itself or substances such as the pulp of other fruits, gums, wood dextrin, and sugars. The reaction is started in slightly acid medium, the acidity being controlled as the action proceeds by the addition of calcium carbonate. Oxygen catalysts such as manganese or titanium salts may be added. Examples :- (1) A litre of mash containing 10 per cent of pectinous material, 0.5 per cent of lemon pith, 1 per cent of citric acid, and 0.005 grams of manganese sulphate is maintained at 25‹ C. to 35‹ C. with aeration; (2) lemon juice and pulp after fermentation, occurring spontaneously, or by the addition of yeasts which develop in the presence of citric acid, until sugar has disappeared and after alcohol has been distilled off, is heated with citrus fruit pith and an oxygen carrying salt, the citric acid content being thereby increased. Sterilization of the raw materials to inhibit prejudicial organisms may be effected by boiling or the addition of antiseptics such as chloroform, toluene, &c.

Title: Improvements in or relating to control devices for pressure autoclaves, dressing sterilisers, disinfectors and the like
Inventor: COOPER CHARLES VERNON
IPC: F16J13/24
Filed: 1953-11-02
Abstract: 747,356. Control devices for autoclaves &c. SLATER & CO. (ENGINEERS), Ltd., J. Nov. 2, 1954 [Nov. 2, 1953], No. 30263/53. Class 81(1). A control device for pressure autoclaves, dressing sterilizers, disinfectors and the like in which the initiation of a cycle of operations of the autoclave is effected by the energization of a pair of relays which also control the locking of the sterile and unsterile doors of the autoclave or the like the relays being released on completion of the cycle of operations. As shewn a sequence of operation in an autoclave is effected by magnetic valves MVSE, MVAE, MVSC and MVAG to allow influx of steam, air or the like to the sterilizer and are operated by relay D, E, F, G, and H each of which is adapted to be energised over time switches TS1-TS5 which are connected in a chain so that when each is energized it operates the next time switch in the sequence after a time interval predetermined for each time switch. The sequence is initiated by pressing a switch J which, provided the sterile and unsterile doors are closed, energizes the relay C which prepares the circuit to a time switch TS over neutral lead relay C, contacts of J, switch S1 (provided sterile door closed), switch S2 (provided unsterile door closed), contact of relay A, line (200/250 VAC). Relay K, over its contact, closes a circuit for relay B extending over neutral lead, relay B, contact of relay K, closed contact of relay A, line. When relay B is energized it locks up over neutral lead, relay B, locking up contacts of relay B, closed contact of relay A, line. Relay C also then locks up over neutral lead, relay C, locking up contacts of relay C, contact of relay B, line. Relay B completes the circuit for the time switch TS extending over neutral lead, relay D, switch TS1, contact of relay C, contact of relay B, line. The completion of this circuit also closes the lock of the unsterile door over relay R1 and of the sterile door over relay R2. The sequence of operations then proceeds, time switch TS1 after a time interval energizing time switch TS2 and so on until time switch TS5 by its operation after a predetermined internal energizing relay A, and hence causes the deenergizing of relays B, C, and K, so that the sterile and unsterile doors are free to be opened once more. If now the sterile door should be opened the unsterile door will be locked over neutral lead, relay R3 contact S1, contact S2 closed contact of relay A (now restored), line. If the sterile door is closed and the unsterile door is opened the relay B is energized over neutral relay B contact S2, closed contact of relay A, line. Relay B when energized then locks the sterile door over neutral lead relay R2, contacts of relay B, line.

Title: A method of preparing a polysaccharide material capable of forming a stable aqueous suspension and a polysaccharide material prepared thereby
IPC: A61K8/04
Filed: 1962-08-08
Abstract: A polysaccharide is converted to a water-insoluble derivative, which is then degraded by hydrolysis sufficiently to obtain a material capable of forming a stable suspension in an aqueous medium upon mechanical attrition. The degraded water-insoluble derivative may be mechanically disintegrated to particles of colloid-forming size. Specified polysaccharides are cellulose, amylose, chitin, xylan and mannan.  The water-insoluble derivatives, prepared by known methods, include ethers, esters, thiourethanes, and oxidation products.  Many derivatives are listed.  The D.S. of the derivative is so chosen that the product is water-insoluble. Hydrolysis of the derivatives may be effected by acids or enzymes.  Mechanical attrition or disintegration of the hydrolysed derivative may be carried out by milling, cutting or by subjection to pressure.  The attrition may be carried out in presence of water, an alcohol, e.g. ethanol, iso-propanol or glycerol, or a sugar solution.  The liquid medium may be omitted when attrition is effected by pressure.  The products of the invention, forming stable colloidal dispersions or thixotropic gels which are resistant to syneresis or bacterial attack, may be used as food additives, pharmaceutical and cosmetic carriers, and fillers for moulding resins.  Examples relate to the hydrolysis and mechanical disintegration of hydroxypropyl and hydroxyethyl cellulose, and cellulose triacetate.  Specification 874,945 is referred to.
