Title: Process and apparatus for the production of mineral and slag wool
IPC: C03B37/06
Filed: 1952-05-16
Abstract: 701,886. Making slag-wool. SMOUT, W. C. P. May 16, 1952 [Jan. 14, 1952; April 2, 1952], No. 13461/53. Class 56 A process for the production of mineral wool or slag wool comprises directing a blast cf air or steam perpendicularly on to a vertically descending stream of the slag over a length thereof which is greater than twice the thickness of the stream. In the Figure a stream 5 of slag of about 10 mm. diameter descends in front of a blower nozzle 2 which is supplied with air at 5 atmospheres pressure through a pipe 1. The nozzle is of U-shape, each arm being provided with a slot 3 two mm. in width and 100 mm. in length. In operation, two flat bands of air act tangentially on the slag stream to draw the filaments of slag wool away from the stream. The recess 4 between the slots 3 prevents any eddying of the shredding medium before it reaches the slag stream.

Abstract: 777,464. Valves. FOXBORO CO. April 29, 1954 [May 11, 1953], No. 12484/54. Class 135. A combined fluid - pressure - operated and manually-actuated valve, comprises a valve body 14 housing a double-beat, plug-lift valve 19 connected by a stem 12 to a flexible diaphragm 23 housed in a chamber 22 supported on the body 14 by a yoke fitting 10. The diaphragm is urged downwardly by pneumatic pressure supplied through a pipe 17 to close the valve and upwardly by a spring 30. Shoulders 46 on the stem 12 coact with bell-crank levers 44 connected together by bars 48 and pivoted on a fixed pin 39. The bars 48 engage adjustable stops 52, 53, to limit the opening and closing movements of the valve. The pin 39 also pivotally mounts a lever 38 formed at one end with a slot 40 slidably mounting a pin 41 and at its other end with a fork 38 engageable by a nut 37 which on rotation of a hand wheel 16 moves along a screwed spindle 34. On alignment of the slot 40 in the lever 37 with recesses 45 in the levers 44, the pin 41 may be moved vertically in the slot to either connect or disconnect the levers, the pin being held in either of the two positions by spring-pressed balls 42. When the levers are connected together the valve can only be operated by the hand wheel 16 and when the levers are disconnected actuation can only be effected by movement of the spring- loaded, pneumatically-operated diaphragm 23.

Abstract: 411,276. Fluid-actuated valves; electric switches. EWART, J. H., 26A, North Audley Street, London. May 1, 1933, No. 12689. [Class 135.] An actuating device for use in connection with water heaters actuated by the flow of water through the heater and adapted to operate the gas valve or a mercury electric switch controlling the heating current operates through a lever passing through a flexible packing adapted to be flexed by the movement of the actuator. The actuator comprises a disc 4 working within a constriction 8 in the casing 1 and mounted on a spindle 9 guided by a socket in a removable cover 7. The lever 12 engages a slot 10 in an enlarged part of the spindle 9 and has a recessed part 13 forming the fulcrum engaged by a flexible washer 14 compressed between coned metallic washers 16 by a screwed ferrule 17. The gas valve 28 is similarly mounted and connected to a lever 36 mounted in a flexible washer similar to the washer 14. The gas and water casings are coupled together by a member 19 carrying the pivot 38 of a double armed lever 39. The lever 39 takes under the ends of the levers 12, 36 so that when the member 4 is raised by the water the gas valve is opened to admit the supply of gas to the burners. The levers may be arranged to engage one another without the interposition of the see-saw lever.

Title: Process for the production of new and improved interpolymers of vinyl fluoride and articles produced therefrom
IPC: C08F8/12
Filed: 1945-05-22
Abstract: New products are formed by hydrolysing an interpolymer of vinyl fluoride and a vinyl organic ester, the mol. ratio of vinyl fluoride to the vinyl ester being from 1 : 3 to 4 : 1, and the interpolymer being soluble in a saturated monohydric alcohol or in a mixture of such an alcohol and an aromatic hydrocarbon.  The term "hydrolysis" here includes hydrolysis by water and by an alcohol.  Suitable vinyl organic esters are those of saturated aliphatic monocarboxylic acids, such as vinyl acetate, formate, propionate, isobutyrate and stearate; but vinyl benzoate may also be used.  Hydrolysis is preferably effected by dissolving the interpolymer in a mixture of a saturated monohydric alcohol and an aromatic hydrocarbon and then treating with a hydrolysing agent or catalyst.  Suitable alcohols are methyl, ethyl, propyl, isopropyl, butyl, isobutyl and cyclohexyl alcohols. Specified aromatic hydrocarbons are benzene, toluene and xylene.  The solvent may also include water.  Alkaline hydrolysing agents, e.g. sodium and potassium hydroxides may be used; for slower reaction, acids such as sulphuric, phosphoric, hydrochloric or para-toluene sulphonic acid may be used.  The hydrolysis should be at least 50 per cent complete.  Fibres may be melt spun or spun from solution in, for example, dimethyl formamide.  They may also be treated with cross-linking agents as, for example, diisocyanates, formaldehyde, dimethylolurea, dimethyloluron, ethers of poly-N-methylol compounds and diacyl chlorides.  The products can also be modified by reacting with such compounds as p-toluenesulphonyl chloride, butanesulphonyl chloride, sodium chloroacetate, maleic anhydride and phthalic anhydride.  They can also be converted into chlorine-containing polymers on treatment with chlorine.  Their heat stability can be improved by adding alkaline materials such as sodium or potassium hydroxide, or amines.  Films, filaments, yarns, bristles, moulded articles, impregnating materials, gasket materials and safety glass interlayers may be made from the hydrolysed interpolymers which can be admixed with pigments, plasticisers, dyes, resins and fillers.

Abstract: 1516292 Semi-conductor devices INTERNATIONAL BUSINESS MACHINES CORP 25 March 1977 [5 April 1976] 12734/77 Heading H1K A first conductivity type region 15 in a semiconductor substrate 10 is formed by ion implantation using an ion impervious mask having an aperture, and then diffusing through the same aperture an impurity determining the first conductivity type. Typically the mask comprises silicon dioxide and silicon nitride layers 12, 13 having registered apertures 16, 14, and the boundary of the ion implanted resin is defined by the aperture 14 having smaller lateral dimensions as compared to that of the lower aperture 16, the ion implantation being carried out either before or after the formation of the lower aperture by etching. The drive-in diffusion at a temperature of at least 1000 C. results in lateral diffusion of the ion-implanted region beyond the edges of the aperture 16, and as such PN junction intersecting of a substrate surface is passivated by the mask, and a metal contact for the region formed subsequently does not short circuit the junction.
