Title: Current limiting fuse
IPC: H01H85/38
Filed: 1972-08-09
Abstract: 1397097 Fusible cut-outs WESTINGHOUSE ELECTRIC CORP 9 Aug 1972 [30 Sept 1971] 37153/72 Heading H2G A fuse structure includes at least one fusible element 60 on an insulating support member 30 inside an insulating casing 20, in which at least an intermediate part of member 30 is made of a normally solid material which, upon arcing evolves a gas but is substantially non- tracking, and the space between the casing and the member 30 is filled with pulverulent arc quenching material 50, such as silver or quartz sand. As shown, member 30 is formed from nine tubular support pieces placed end to end and made of boric acid compressed by a minimum isostatic pressure of 25,000 Ibs. p.s.i., or compressed calcium carbonate. A notched silver ribbon 60 is wound round the support, the ends, which may be doubled over to increase the cross-sectional area, being trapped between caps and terminal members 82 and 72 and 84 and 74 respectively. The ends of elements 60 may be bound to support 30 by glass tapes. A bead of tin or solder material which melts between 182 and 232 C. is provided on element 60 to promote melting of the fuse. Terminal members 72 and 74 also hold the flattened ends of support member 30. The casing 20 is of glass-reinforced melamine or epoxy-resin material. When arcing takes place the boric acid support member emits water vapour and quenches the arc. As the member is non-tracking no leakage current flows and the support member does not break down. If a calcium carbonate member is used, carbon dioxide or monoxide is evolved. The support member may be made of a single block, and may be solid or have a core which does not evolve gas, e.g. a ceramic or other inorganic material. If the member is hollow a high resistance fusible wire, co-operating with indicating means, may be placed in it.

Title: Sonic atomizer for liquids
Inventor: LANG ROBERT JOSEPH
IPC: B01J19/10
Filed: 1962-10-01
Abstract: 955,405. Spray producers. ESSO RESEARCH & ENGINEERING CO. Oct. 1, 1962, No. 37164/62. Heading B2F. Liquids are vaporized by a method wherein a gas is subjected to sonic or ultrasonic energy vibrations and thereby given a pulsating movement and the liquid is flowed into an area of said pulsating gas movement and thereby vaporized. High frequency alternating voltage from a source 10 is applied to a piezo-electric element 18 which is bonded to the larger end of a conical resonator element 22. The element 18 is of barium titanate or other suitable ceramic material. The element 22 is of aluminium, or it may be of brass on stainless steel, and it is maintained in spaced relation to a ring 34 by screws 38, directed radially inwards and having pointed ends which bear on the element 22 along a circumference which coincides with the node of the vibrations therein. Screwed into the smaller end of the resonator element 22 is a bolt 24 and just clear of the bolt-head is a plate 42 in which is an orifice 44 in axial alignment with the element 22 and bolt 24. The bolt is exchangeable with others of different head diameters. The plate 42 is clamped to a ring 48 which may be adjusted upwards and downwards, being carried by a yoke 54 adjustable on a post 56. The post 56 rises from a block 62 which is slidable on the base 26, as controlled by a screw-threaded rod 72 and spring 82, to give backwards and forwards adjustment to the plate 42. The orifice 44 is surounded by a lip extending away from the resonator. The liquid to be atomized is directed to the face of the plate 42 through a feed tube 84, which is adjustable in position, and runs down on to the lip around the orifice. The high frequency vibration of the element 22 causes the bolt 24 to act as a pump and send a rapidly pulsating air stream through the orifice, and as liquid passing over the edge of the lip is struck by the pulsating air jet it is thereby atomized. As the bag 86 of atomized liquid is driven away from the orifice it will tend to draw into it air, in the direction shown by the curved arrows, Fig. 1, which, if the liquid is fuel oil, assists in forming a combustible mixture. To increase the heating-up effect on the liquid there may be a group of lipped orifices instead of a single one and to increase the air pumping effect there may be a collar on the plate, on the reverse side from the lip or lips, surrounding the head of the bolt 24. In a modification the orifice plate may be horizontal so that the liquid forms a pool, from which some flows over the orifice lip. Experiments are described dealing with the effect of orifice diameter, distance between the bolt head 24 (transducer tip) and the orifice, air jet velocity and other factors with respect to different liquids atomized.

Abstract: 1,271,822. Gas turbines; axial-flow compressors and pumps. SULZER BROS Ltd. July 24, 1969 [July 26, 1968], No. 37290/69. Headings F1C, FIG and F1T. In a turbine, compressor or like machine having angularly adjustable stator blades 5, each blade is journalled in a respective housing 4 secured to the outer side of the machine casing 1 so that the bearing surfaces are remote from the working fluid-flowing through the machine. Each housing 4 has spaced tubular walls 9, 20 defining cooling air chambers 14, 15 surrounding plastics dry running bearings 10, 11 in which the blade journal 8 is mounted. The chambers 15 of circumferentially adjacent housings 4 are inter-connected by resilient bellows 16 so that cooling air supplied through two diametrically opposite pipes 19 can flow to all the chambers 15. The cooling air from the latter passes through ports 18 into the chambers 14, each of which contains a U-shaped sheet metal baffle 36 to direct the air along the walls of the chamber. The neck 6 of each blade has cooling fins 23 around which is tightly fitted a sleeve 30. Each of the fins 23 has a segment 35 milled away, the milled regions alternating from fin to fin by 180 degrees so that the cooling air leaving region 46 at the open lower end of chamber 14 follows a tortuous path in flowing over the fins 23 before exhausting through holes 39 in sleeve 30 and ducts (not shown), into the working fluid. Sleeve 30 is a loose fit within a plate 22 and is urged by spring 31 against a recess 32 in a ring 33. Plate 22 is clamped in position by housing 4, the latter being secured to casing 1 by screws passing through flange 21. A thrust bearing comprising a collar 24, two discs 25 and a retaining ring 26 is provided at the top of each journal 8, leakage past the ring 26 being prevented by an O-ring seal 55. A collar 27 carries the blade adjusting lever 28. The journal 8 is formed from a material having good dry running properties and is shrunk or force fitted over the blade stem 7. In a modification, Fig. 5 (not shown), the journal 8 is cast with the blade, the aero-foil portion 5 being of heatresistant steel and the journal 8 of dry running material. The junction between the two materials is in the region of the fins 23. In this modification additional cooling of bearing 10 is effected by diverting some air from region 46 to a chamber (44) in journal 8 in the region of bearing 10, the air exhausting to atmosphere through bores (47), 40 in the journal.

Title: Production of alkylphenols
Filed: 1961-10-18
Abstract: In the method of producing a p-alkylphenol by fusing an alkali metal p-alkylbenzene sulphonate with caustic alkali, an alkali metal salt of an o-alkyl phenol is added to the alkali metal p-alkylbenzenesulphonate prior to fusion preferably in the proportion of 4-12% of the amount of the alkali metal p-alkylbenzenesulfonate. In an example p-toluenesulphonic acid monohydrate was neutralized with caustic soda and o-cresol added followed by an equivalent amount of sodium hydroxide solution. After removal of most of the water by evaporation the wet cake of sodium p-toluenesulphonate containing sodium o-cresolate was dried and added over a period of 2 1/2 to 3 hours with efficient agitation to molten sodium hydroxide, the temperature being maintained at 320-340 DEG  C. throughout the addition and for 2 hours longer after the addition was completed. The molten mass was allowed to cool water was added to dissolve the reaction mixture which was cooled and neutralized and then distilled with steam. The bulk of the cresol (lower layer) in the distillate was separated from the water and the remaining aqueous phase was extracted with methylene chloride.  The combined extracts were evaporated to remove methylene chloride and the resulting cresol added to that separated from the distillate giving a mixture of 94% p-cresol and 6% o-cresol.  After deducting the amount of O-cresol added to the fusion mixture, the product corresponded to substantially 100% p-cresol.  The yield of p-cresol thus obtained was 66% based on the amount of p-toluene-sulfonic acid used.  The p-cresol can be separated from the o-cresol by fractional distillation.  Other examples are given.
