Title: Improvements in or relating to Non-Laminated Flexible, Silverized and Coated Webs.
Inventor: SCHARF WALTER GEORGE
IPC: C23C14/20
Filed: 1966-06-13
Abstract: 1,154,571. Vacuum depositing silver. W.G. SCHARF. June 13, 1966 [Jan. 20, 1966], No.26326/66. Heading C7F. [Also in Division D1] A non-laminated, flexible, silverized and coated web is produced by vacuum depositing a silver layer on to a surface of a flexible thermoplastic base web 11, e.g. being transported from a supply roll 12 over evaporating silver in vessels 21 to a wind-up roll 13 within a vacuum chamber 10 at a pressure of 10<SP>-2</SP> to 10<SP>-8</SP> torr, coating the silver layer with a wet thermoplastic film, e.g. using a coating solution of an ethylene terephthalateethylene isophthalate copolyester in diethylene dioxide to which an amber dye may be added, levelling the wet film to produce a pore-free layer and drying. The base web may be polymerized ethylene glycol terephthalate transported at constant speed and at uniform tension by a magnetic clutch 24 coupled to the supply roll 12; at least one guide roll 17, 18 may be cooled e.g. by refrigerant 27. The coated web may be subsequently slit to produce a thread about which a supporting thread of silk or nylon having a different colour may be twisted.

Title: Apparatus for the manufacture of dried milk and similar milk products
Inventor: MEYER ERNST
IPC: A23C1/04
Filed: 1962-07-10
Abstract: 961,375. Weighing apparatus. SILKEBORG MASKINFABRIK A.S. July 10, 1962, No. 26441/62. Heading G1W. [Also in Divisions A2 and B2] Dried milk powder obtained by spray-drying atomised liquid milk by air in a chamber 2, Fig. 1, is conveyed by the air to one or more cyclone separators 8 from which it is discharged by two or more gates 18, 19 Fig. 2, into a stream of cooling air flowing in a pipe 10 at a higher pressure. Each gate opens under the weight of the powder deposited thereon and has a counterweight 22, 23, or spring to return it to its closed position. In order to prevent the lower gate from opening when the upper gate is open, there is-provided either an articulated mechanism (not shown) incorporating a locking lever for the lower gate, or a pressure leakage across the lower gate such that the pressure differential across it is steadily reduced. In the latter arrangement, due to the higher pressure from beneath it, the lower gate remains closed when the upper gate opens to discharge a quantity of powder on to it, but after the upper gate has closed the pressure differential across the lower gate quickly diminishes because of the permitted leakage across the gate, until it is insufficient to prevent the gate loaded with powder from opening.

Patent GB-928776-A (GB)
Title: Method for seasoning foodstuffs
IPC: A23L27/23
Filed: 1961-07-25
Abstract: Flavour of foods is improved by adding one at least of the compounds deoxy-51-inosinic acid, deoxy - 51 - guanylic acid, deoxy - 51 - xanthylic acid and amides and non-toxic salts, e.g. alkali metal, alkaline earth metal, ammonium and histidine salts, thereof.  The compounds can be added to soups, sauces, pastes, sausages, canned foods, salads, boiled foods, pickles, vinegars, alcoholic drinks, table salt, breads, and fermented foods and drinks exemplified by soya sauce, moromi, miso and sake, the preparation of which involves Aspergillus oryzae, A. oryzae-flavus or A. sojae.  The compounds may be used in conjunction with such condiments as monosodium glutamate, sodium succinate and sodium inosinate.  Deoxy-51-inosinic and deoxy-51-guanylic acid are obtained on hydrolysing the deoxyribonucleotides of bacteria, thymus, ox semen and herring milt with enzymes of snake venom or certain Schizomycetes or Ascomycetes micro-organisms, further hydrolysis to deoxyribonucleosides by any phosphomonoesterase in the enzyme system being inhibited by an arsenate, phosphate, cyanate or fluoride, or by a phenol or cresol. Deoxy-51-cytidilic and deoxy-51-iridylic acids may accompany the deoxy-51-inosinic and deoxy-51-guanylic acids. Deoxy-51-xanthylic acid may be obtained by converting deoxy-51-guanylic acid to its 2-diazonium salt and hydrolyzing this salt to introduce a hydroxyl group.  Examples describe preparation of the food additives by hydrolyzing deoxyribonucleic acids of herring milt and calf thymus by culture filtrates of Streptomyces aureus, Aspergillus quercinus, Botryosphaeria ribis chromogena and Helminthosporium sigmoideum, passing the hydrolysate through active charcoal, eluting the charcoal and concentrating the eluate, the eluate being fractionated with the aid of ion-exchange resin, if desired.

Title: Improvements in or relating to devices for producing electro-magnetic waves of a wavelength of the order of not more than one centimetre
IPC: H01J25/30
Filed: 1949-10-21
Abstract: 681,268. Electron transit time apparatus. PHILIPS ELECTRICAL, Ltd. Oct. 21, 1949 [Oct. 26, 1948], No. 27068/49. Class 39(i) A device, for producing electromagnetic waves of a wavelength of the order of not more than one centimetre, comprises an electron tube by means of which a number of electron beams is passed through apertures in a resonator at potential nodes in such direction that the beams are deflected by the high frequency magnetic field, the said electron beams being reflected by a reflecting electric field with such displacement and time shift, that, on re-passing through the apertures, or divisions of the same, in the resonator, they give out energy, thereby maintaining oscillations in the resonator. In one embodiment, Fig. 1, five cathodes 1 having' circular emissive surfaces are arranged to project electron beams through an aperture in a screen electrode 2 and through two slots 4, each about ¥ #in length, in a rectangular cavity resonator 3 so that the beams cross the resonator at potential nodes. The beams are subjected to alternate deflections to the left and to the right by the alternating magnetic field in the resonator and are reflected by an electrode 5 which is at cathode or a slightly lower potential. Registering with the cathode and arranged in front of the electrode 5 are five wires 6 which have a slightly lower potential than the electrode 5 and which serve to amplify the beam deflections. The spacing between the electrode 5 and the resonator 3 is such that the lateral displacement of the reflected beams is one quarter of a wavelength. The reflected beams thus pass through the resonator at potential antinodes and give up energy to the resonator. A cylindrical arrangement, Figs. 3 and 4, comprises a cylindrical cathode 7 surrounded by a screen 8 having apertures 9 regularly distributed about its circumference opposite the potential nodes in a resonator 10 comprising two concentric cylinders closed at the ends and provided with elongated slits 11 and 12 in line with the apertures 9. The electron beams are focused by eight bars 13 connected together by two rings 14. Four flat rings 15 are provided opposite the apertures 9 to amplify the beam directions and the reflecting field is provided by a cylindrical electrode 16.

Abstract: 1397270 Coating tubes VALLOUREC (USINES A TUBES DE LORRAINE-ESCAUT ET VALLOUREC REUNIES) 12 June 1972 [10 June 1971] 27450/72 Headings B2E and B2L The external surface of a tube is coated continuously with a synthetic material, e.g. a thermoplastic or thermosetting material, by advancing and rotating the tube, heating the tube until at least its exterior surface is raised to a temperature greater than the temperature of fusion or adhesion of the synthetic material, allowing to fall from one or more stores disposed at fixed locations above the tube the synthetic material in a pulverulent state, and then heating the tube to fuse or thermoset at least part of the coating. Preferably the tube then passes into a cooling device, e.g. constituted by projecting or sprinkling water. Sections of tube may be joined end to end with the help of sleeves to obtain a continuous operation and also to protect the extremities of the sections of tube which must not be coated with plastics material. Alternatively the tube sections may be supported at their extremities by means of suitably disposed carriages. As shown in Figure 1 tube sections 2 are connected by sleeves 3 and a helical movement communicated to the tube by the axial movement of the tube and a rotary movement imparted by three discs 5. The tube is then introduced into a heating furnace 6 constituted, e.g. by a solenoid and then under a feeder 7 which distributes a curtain of pulverulent thermoplastic material 8 in the axial direction of the tube. The curtain of thermoplastic pulverulent material 8 crosses a screen 9 endowed with a horizontal vibratory movement, the plastic material falls on to the tube and the rest is collected in bucket 10. The tube then passes into radiant heater 11 and then is subjected to spraying by water from tube 12. The tube sections are then separated and placed on storage grate 14. In a modification of the apparatus as shown in Figure 2 the feeder 7 comprises a slot 7A adjustable by regulator 7b and the volume of pulverulent material which crosses the screen 9 falls on to a rolling cloth 15 inclined so as to lead the pulverulent material on to the upper generatrix of the tube 4. Surplus material falls into trough 10 and transferred into a cyclone centrifuge 16 where it is separated from its transport air. Several feeders may be used to successively distribute on the periphery of the tube materials of different types to obtain multiple layer coatings. Thermoplastic materials mentioned are polyethylene, polypropylene, polyvinyl chloride, polyamide. Thermosetting materials mentioned are epoxy resins.
