Abstract: 1,178,180. Coated semi-conductors. WESTERN ELECTRIC CO. Inc. 21 March, 1967 [8 April, 1966], No. 13095/67. Heading H1K. Silicon nitride, alumina, or aluminum silicate is deposited to form a layer on the surface of a semi-conductor substrate, for example on to a silicon body or on to a silicon oxide layer on such a body. The deposited layer is shaped by covering it with a masking layer of silicon oxide, molybdenum, or platinum and etching with a hot phosphoric acid solution. The masking layer itself may be formed from a uniform layer by using conventional photoresist techniques in conjunction with etchants such as buffered hydrofluoric acid (for silicon oxide), nitric acid (for molybdenum), or aqua regia (for platinum). Silicon nitride may be deposited on to a heated substrate from a gas mixture of silane, ammonia, and hydrogen. Alumina may be deposited by mixing a stream of hydrogen/aluminum chloride with one of carbon dioxide, silicon oxide by mixing a stream of hydrogen/silicon tetrachloride with one of carbon dioxide, and aluminum silicate by mixing all these components.

Title: A process for the production of spinnable polyethylene terephthalate from polyethylene terephthalate waste
IPC: D01F6/62
Filed: 1960-04-13
Abstract: Spinnable polyethylene terephthalate is made from polyethylene terephthalate waste by (1) exposing the waste on the countercurrent principle to a stream of superheated steam, the inlet temperature of which is 280 DEG C. to 450 DEG C. and the outlet temperature of which is not below 200 DEG C., (2)adding an aromatic or hydroaromatic ketone or diketone (e.g. 4-methylcyclohexanone or benzil) to the melt thus formed and, (3) polycondensing the melt. Treatment with the steam is preferably effected in a vertical jacketted tube into which polyethylene terephthalate fibre waste is fed at the top, steam at 420 DEG C. is fed at the bottom and steam at 200 DEG  to 220 DEG C. is fed at the mid-point.  The steam removes textile auxiliaries from the waste and the ketones combine with metals in the melt to form colourless compounds.  There may be added to the melt, prior to polycondensation, ethylene glycol, pigments, dyestuffs, stabilizers or optical brighteners.

IPC: F42C1/09
Abstract: 133,066. Marlin Arms Corporation, (Assignees of Barlow, L. P.). Sept. 18, 1916, [Convention date]. Projectiles; fuses. - Relates to bombs comprising an explosive shell within an external casing from which the shell is expelled rearwards on impact, the explosion of the shell taking place above ground after it has thus rebounded for a given time or a given distance. According to the invention, the shell is expelled from its casing by mechanical means such as a spring, instead of by an explosive charge. In the form shown, the shell 5 is held in an outer tubular casing 1 against a spring 4 by spring detents 10, which are released when, on impact, the shell moves forward in the casing 1, increasing the compression of the spring. The shell thrown up by this spring is exploded when a short length of cable 16 becomes taut and pulls a percussion cap 23 against a firing-pin 22 as described in Specification 133,063. The outer casing has a winged tail 2 and is welded to a head-piece comprising a central dome 6<1> and forwardly projecting lugs 6<2>, which expand on impact and limit the penetration of the casing into the target.

Wet-separating.-Carbonaceous material, particularly coal, is separated in a solution of such specific gravity that the light constituents float and the heavy constituents sink, and the separated light material and preferably also the heavy material is freed from adhering solution by downward displacement with a continuous or unbroken body of water. In the apparatus shown, the coal, preferably first freed from dust, is fed through a hopper 5 to a vessel 1 provided with an agitator 10 and supplied with, for example, calcium chloride solution from a tank 2. The light coal forms a layer 11 which overflows to a tower 16, to which, when the coal is to be washed, water, or weak solution followed by water, is admitted from a pipe 20. The calcium chloride solution is displaced by the water and collected in a vessel 24, weaker solution being collected in a vessel 28, and finally the wash water being discharged through a pipe. 30. The coal is removed from the tower 16 by opening a slide 18 and displacing a grid 19. The heavy constituents of the coal are removed by an elevator 31 and may be similarly washed in a tower 32. The solutions from the vessels 24, 28 are pumped to the supply tank 2 and a concentrator respectively; or both solutions may be sent to a concentrator. The solution in the concentrator is rendered alkaline before being returned to the separating-vessel 1. The separated constituents may be further treated in other solutions. Drainage in the towers may be assisted by pressure or suction, or the towers or their contents may be agitated. In a modified construction of the separating vessel 1, the coal is delivered by a screw conveyer through a side opening where it is agitated by a jet of liquid. and the floating material is removed by an end-- less band of scrapers.
