Title: Improvements in or relating to methods of coating surfaces by evaporation
IPC: H01J40/06
Filed: 1941-12-23
Abstract: 570,200. Coating surfaces with quartz. CINEMA-TELEVISION, Ltd., and SOMMER, A. Dec. 23, 1941, No. 16553. [Class 56] [Also in. Groups II, XV and XL] Surfaces within an evacuated envelope, particularly a photoelectric cell or other electron discharge tube, are coated by evaporating a substance, e.g. quartz, from a source through apertures in a foraminated member on to a supporting member to form a layer, the foraminated member being so disposed as to cause the formation of a layer of more uniform thickness than if the member was not interposed between the source and the supporting member. The source is usually unsymmetrically disposed with regard to the supporting member. A pellet 2 of the coating material is supported on a helix 3 connected to leads which extend to the exterior of the envelope 1 and screened from the portion of the latter forming the window by a shield 4, e.g. in the form of a cylindrical or hemispherical cup. A foraminated member 6 comprising a mesh or grid of wire or fibre is so disposed that when the coating material is evaporated from the pellet 2 by passing a current through the helix 3, only a portion of the evaporated material reaches the envelope nearest the helix, while in a position most remote from the pellet all the coating material leaving the pellet reaches the envelope. The grid or mesh may be provided with spacing or apertures and/or wire diameter of graded size.

Title: Improvements in and relating to apparatus for delivering measured quantities of liquid
IPC: B67D7/16
Filed: 1930-05-29
Abstract: 353,605. Delivering measured quantities of liquids. SOC. D'ETUDE DE DISTRIBUTEURS AUTOMATIQUES (S.E.D.A.), 22, Rue d'Athenes, Paris. May 29, 1930, No. 16678. Convention date, May 29, 1929. [Class 106 (v).] The movements of the slide valve 17 controlling supply to and discharge from the measuring chamber 1 are dependent on a float 49 in a discharge chamber 50 the capacity of which is at least equal to that of the measuring chamber, and the outlet from which is smaller than the inlet from the measuring chamber whereby the float will rise as long as the measuring chamber.contains liquid. : The indicator 62 is turned to display through the opening 62a the number of units required. A cam 59 releases the rod 56 which under the action of a spring 57 ceases to obstruct the bell-crank lever 26. The 'compression spring 30 surrounding the rod 28 then moves valve 17 to the left permitting the chamber 1 to be charged through the pipe 23. As the rod 28 falls the collar 42 engages a fork 41 and lifts a pawl 39 from engagement with the hub of a lever 44. The float 49 then falls to the bottom of the chamber 50. As the measuring chamber 1 fills air is compressed in the chamber 69 until the float 9 closes a valve 10. Increased pressure then acts on a diaphragm 20 and moves the valve 17 to the discharge position. The pin 36, owing to the pawls 39, 43 being out of engagement, slides into a groove 37 and locks the rod 28 as it rises. The compressed air in chamber 69 rapidly effects the discharge of the chamber 1 into the chamber 50, but the rate of discharge from the latter is reduced by fitting a ring 53 in the nozzle. The float rises and re-engages the pawls 39, 43 ; when it falls, owing to complete discharge of the chamber 1, the pin 36 is withdrawn, the spring 30 again becomes effective to move the valve 17, and pumping may be resumed. Downward movement of the rod 28 causes the bell crank 26 to depress the rod 56. This, through the ratchet and pawl 64, 65 turns the indicator plate 62 one step towards zero, and works a counter 68. Quantity adjusting masses 15 are lodged within a tube 14 in the chamber 1.

Title: Improved method of and means for effecting the sublimation of volatisable substances
IPC: B01D7/00
Filed: 1927-06-23
Abstract: 290,849. Thame, J. June 23, 1927. Sulphur.-The sublimation of sulphur is effected by introducing the substance in small quantities into a vaporizing retort, and conveying the vapour by suction or by means of a current of inert gas to a cooled condensing chamber fitted with scrapers to remove the deposit from its walls and convey it to discharge orifices which are preferably fitted with air-locks. The operation of the scraper and of the air-locks may be automatically effected by means of a clock-driven switch, and the temperatures of the retort and the condenser may be thermostatically controlled. In the illustrated modification, molten sulphur contained in the jacketed tank 4 is admitted in quantities controlled by a float valve 8 to the retort 9 heated by an oil burner 14 controlled by a thermostat 21, 22. The vapour passes to a condenser 30 comprising a cylinder 27, Fig. 2, surrounded by a jacket 29. The cylinder contains a scraping device comprising a hollow watercooled body 33 carrying a semicircular blade 34 to scrape the upper surface of the cylinder and a series of ploughs 35 to break up the thicker deposit in the lower portion. By means of the motors 40, 41, controlled by the relays 54, 55 and clock-driven switch 50, the scraper is moved to and fro along the cylinder and the deposited sulphur is displaced towards the discharge openings 63, 64, which are fitted with air-locks also controlled by the switch 50. The discharged sulphur falling into the conduit 74 is conveyed away by an air blast. The condensing portion of the apparatus may be used alone for the recovery of sulphur from natural sulphur vapours.

Abstract: 734,342. Separation of dust from gas. GLINKA, C.. July 13, 1951, No. 16739/51. Class 8 (2). Fly ash is separated from hot furnace gas having left the combustion chamber by passing the hot fly-laden gas through a plurality of passages and over sloping surfaces down which the ash flows in liquid form, the surfaces being maintained at a sufficiently high temperature by the provision of additional heating means. As shown, hot fly entering a water-cooled cylindrical chamber 1, Fig. 1, is further heated by a coal combustion nozzle in the inlet 10 and is thereafter deposited on and drips from spaced inclined baffles 6 radiating from a concentric water-cooled cylindrical chamber 3 having clean gas outlets 7. In a modification fly from a combustion chamber 12, Fig. 4, passes up between ducts 15 traversed by hot gas from an additional chamber 14, the ash being thereby liquefied and drips to a slag outlet 16. In a further modification the ash is deposited in liquid form on the exterior of hollow ceramic bodies containing electrical heating elements and arranged in rows 17, 17a, 17b, Fig. 5. Final cleaning is effected by a granular head 18 and liquid ash is discharged through an outlet 20.

Title: Preparation of silico-urethanes
Inventor: DODGSON DOUGLAS PETER
IPC: C08G77/54
Filed: 1958-05-27
Abstract: A silico-urethane is made by reacting an organic silicate, containing a Si-bonded OH group and obtained by partial hydrolysis of the silicate with water, with an organic isocyanate.  Reactants specified are:-silicates-tetraethyl- and diethyldiphenyl-orthosilicates and their partial hydrolysates (mono- and poly-meric); isocyanates-toluene-2 : 4-, toluene -2 : 6-, phenyl-1 : 4-, hexamethylene-, and propylene -1 : 2-diisocyanates, 4 : 41-diisocyanatodiphenylmethane, 4 : 41 : 411-triisocyanatotriphenylmethane, 4 : 41-di-isocyanatodiphenylpropane, and toluene -2 : 4 : 6-triisocyanate.  Monoisocyanates may also be used.  The process can be effected by mixing the silicate, isocyanate and water together at room temperature or up to 100 DEG C., preferably in the presence of an inert liquid diluent, e.g. light petroleum, cyclohexane, benzene or toluene.  In the example tetraethylsilicate, water and toluene -2 : 4- diisocyanate were mixed together with stirring to give a mobile slurry which on standing became solid; the solid was then powdered and soluble by-products removed by ether extraction to yield an insoluble residue which on heating to 150 DEG C. became soft and could be pulled into fibres; on further heating at 160 DEG -180 DEG C. it formed a hard yellow solid which was infusible at 200 DEG C. and possessed good electrical insulation properties.
