Inventor: PRATT DESMOND CHARLES FURBY
IPC: F23G7/04
Filed: 1958-05-22
Abstract: 878,775. Burning black liquor. COURTAULDS Ltd. May 22, 1959 [May 22, 1958], No. 16434/58. Class 51 (1). Waste aqueous liquid containing oxidizable components, such as pulp mill effluent, is passed into a vessel C where it is evaporated by heated gravel, leaving oxidizable deposits on the gravel. The gravel is passed to a reaction vessel A where the deposits are burned by air entering through a pipe H, which may fluidize the gravel. The gravel, reheated by the combustion of the deposits, passes through a sealing and metering valve B to evaporate further supplies of liquid. To start the continuous process, the gravel in the reaction vessel A is heated by oil burners or other means. The evaporation vessel C may be replaced by a pneumatic conveyer, the steam formed by the evaporation acting as the conveying medium, or the reaction vessel may be replaced by an air-operated pneumatic elevator in which the deposits are burned. A cyclone separator F ensures that only gravel is passed back to the reaction vessel A through a sealing and metering valve G. Specification 812,438 is referred to.

Abstract: 1305675 Pipe couplings; valves MORGAN CONSTRUCTION CO 24 May 1971 [15 June 1970] 16560/71 Headings F2G and F2V [Also in Division B3] A pipe coupling comprises a first coupling member 22 movable into and out of engagement with a second coupling member 58, the coupling members each having at least one passageway 30, 64 for liquid terminating in flat faces 44 which can abut with a seal ring 108 between them, the passageway 30 being closed by a spring-biased valve 34. As shown, the passageway 64 is also closed by a spring-biased valve 70. With the coupling members 22, 58 in abutting relation as shown, admission of liquid through a duct 80c to act on a valve piston head 70a slides the valve 70 leftwards against the bias of its closing spring: its head 70b then engages the head of the valve 34 which, too, is slidden against the bias of its spring to its open position. The coupling member 58 is mounted for horizontal movement by rollers 60 in guideways 56 carried by a vertical plate 54. The first coupling member 22 is carried by a roll housing (12), Fig. 1 (not shown), in a rolling mill, movable towards and away from the plate 54 on rails (20). To engage the coupling, the roll mill housing is moved along its rails to abut the first coupling member 22 with the second coupling member 58, the latter then being slidden rightwards by reason of its rollers and guideways 60, 56 to contact spring buffers 62. A double acting liquid servo 92 is energized to pivot clamp levers 96a, 96b about their pivot pins 102 on the guideways 56 and engage rollers 104 at their ends behind cam surfaces 106 on the first coupling member 22, thus clamping the two coupling members together. More than one passageway 30, 64 may be provided in the coupling members 22, 58. The feeds to the two passageways 30, 64 are by way of pipes 24, 26 and a flexible tube 82. The valve (84), Fig. 2 (not shown), controlling the supply of liquid to the duct 80c and the valve piston head 70a for actuation of the valves 70, 34, may simultaneously control the supply of liquid through ducts 80a, 80b to the two valves. Alternatively the ducts 80a &c. can be supplied from an independent source. In a modification, the valve in the second coupling member (112b), Fig. 4 (not shown), is omitted, and the valve in the first coupling member (112a) is a simple check valve (140), opened by the pressure of liquid admitted through passages (124 &c.) in the second coupling member when the two are abutted.

Title: Process for the preparation of sulphenamido and sulphonamido derivatives of pyrimidine compounds
IPC: C07D239/69
Filed: 1942-04-29
Abstract: 557,055. Pyrimidine sulphenamides and sulphonamides. MAY & BAKER, Ltd., and BARBER, H. J. April 29, 1942, No. 17144. Divided out of 550,446. [Class 2 (iii)] Sulphenamido derivatives of pyrimidine are prepared by reacting under alkaline conditions and in the absence of a hydroxylic solvent an aromatic sulphenyl halide having in the para position a halogen atom or a nitrogen-containing group capable of conversion into an amino group and a pyrimidine compound containing an amino group. The sulphenamido compounds so prepared may then be oxidized to the corresponding sulphonamido compounds, by treatment with an oxidizing agent, preferably potassium permanganate, in alkaline solution. Nitrogen-containing groups which may be present in the para position of the sulphenyl halide include acylamino, nitro, azo and hydrazo groups. The necessary alkalinity during the reaction may be obtained by using an excess of the amino-pyrimidine or by adding an alkali such as sodium carbonate. The sulphenamido compound need not be isolated and purified before being oxidized to sulphonamide. The amino-pyrimidines which may be used include alkyl pyrimidines particularly 2-amino- 4:6-dimethyl-pyrimidine. In examples (1) p- Nitrobenzene-sulphenyl chloride is added to 2-amino-pyrimidine in ether solution at room temperature. The product is precipitated with water after extraction with acetone, and oxidized to 2-(p-nitrobenzenesulphonamido)- pyrimidine with potassium permanganate. (2) Para-nitrobenzene sulphenyl chloride is added to 2-amino-4:6-dimethyl pyrimidine in ether solution as in example (1) to give 2-(p-nitrobenzenesulphenamido)-4:6-dimethyl - pyrimidine which is filtered and then oxidized with alkaline permanganate to the corresponding sulphonamido compound.

Abstract: 803,298. Semi-conductor devices. WESTERN ELECTRIC CO., Inc. June 5, 1956 [June 8, 1955], No. 17339/56. Class 37. A germanium PN junction device is stabilized against changes in the conductivity type of its exposed P-type surfaces by mounting in a sealed housing filled with oxygen. In one embodiment a grown NPN germanium bar 17 in which the P-type zone is thin is mounted between electrodes 16 which are sealed through a flanged metal sleeve 13. The germanium is then cleaned by etching in a mixture of 25 parts nitric and 3 parts hydrochloric acid, washed first in deionized water and then in ethyl alcohol and afterwards blown dry with nitrogen. The mounted bar is then stored in dry nitrogen until it can be encapsulated by welding a cover 11 to the flange of sleeve 13. The housing thus formed is then evacuated, refilled with oxygen and sealed by pinching off and welding the tubulation 12. An alloy type PNP transistor comprising indium or gallium emitter and collector electrode blobs fused to opposite faces of an N-type germanium wafer to one of which a ring base electrode is attached may also be stabilized by mounting in oxygen. The oxygen prevents the surface of the P-type germanium from being converted to N-type and thus shortcircuiting the junctions. The invention is applicable only where the surface current paths in the P-type material are small compared with similar paths in the N-type material since the oxygen tends to convert the N-type surfaces to P-type. Specification 760,563 is referred to.
