Title: Improvements in fuel systems for gas turbine engines
Inventor: TYLER STANLEY RALPH
IPC: F02C9/32
Filed: 1959-10-12
Abstract: 957,013. Gas turbine plant. DOWTY FUEL SYSTEMS Ltd. Oct. 7, 1960 [Oct. 12, 1959], No. 34510/59. Heading F1G. [Also in Division G3] A gas turbine fuel system includes an engine speed sensitive governor 9, 14 arranged to adjust means 13 to vary the compressor output pressure applied to means for adjusting the fuel flow to the engine. The governor consists of a flyweight 9 pivotally mounted at 12 on an engine driven shaft 1 and has a spring-loaded arm 13 to co-operate with a fixed bleed orifice 15 in a duct 23 conveying compressor output pressure to a bellows 28 connected by a strut 29 with an evacuated bellows 27 and by a pin 31 with a lever 32 pivoted at 33. Movement of this lever adjusts a half ball valve 34 cooperating with the bleed orifice 35 of a doubleacting piston 45 which is supplied with fuel under pressure through a line 47 and a restrictor 48 and operates a piston valve 41 in the main fuel supply line 42, 44 to the engine. The valve 41 is coupled by a spring 37 to the lever 32 which is also acted upon by a pre-set spring 36. A gear pump 4 driven by the shaft 1 supplies fuel through a line 7 to a valve unit 52 including a spring-loaded valve 54 to prevent fuel from being supplied to the piston 45 during starting and a by-pass valve 65 to maintain the pressure drop across the valve 41 in the main fuel supply line constant. The valve 65 is operated by a piston 63 subjected to the pressure drop while the valve 54 has an aperture 55 to maintain a constant supply to the valve 41. When the turbine is to be stopped, a solenoid by-pass valve 74 is opened to allow a valve 71 to close the main fuel line. The governed speed may be adjusted over a small range by a manually set restrictor 21.

Abstract: 1,199,446. Conveyers. HARRIS-INTERTYPE Ltd. 23 July, 1968 [27 July, 1967], No. 34514/67. Heading B8A. Apparatus for transversely aligning articles, e.g. bundles at a tying station, comprises driven conveyer rollers 7 of which one group 17 of three is provided with a beam 21 which may be lifted, by a cylinder device 25, so as to disengage temporarily a bundle supported on the rollers. A plate 47 is mounted for reciprocal movement in the longitudinal direction of the roller axes, such movement being derived from cylinder-operated rack and pinion means 37, 39 which drives a chain 45 linked to the plate 47. A bundle to be tied is fed in a direction A until its leading edge has engaged the group 17 of rollers whereupon drive to all the rollers is cut off. The bundle is then raised by the beam 21 and the plate 47 operates to push the bundle in the direction B, to a tying machine (not shown). On completion of the tying operation the plate 47 is returned to its original position and drive to the rollers is restored to remove the bundle from the tying station. The sequence of operations is automatic and is initiated by the bundle itself. In place of the rollers 7, conveyer belts or chains may be used, the beam being replaced by a slotted beam or a number of smaller beams. The apparatus is supported on castors 3 and is secured to a conventional tying machine by means of clamping jacks 5. Alternatively the apparatus may be built into a tying machine. The roller group 17 is removable to aid assembly of the apparatus within the tying machine.

Patent GB-445631-A (GB)
Title: Improvements in or relating to the manufacture of goods of or containing sponge-likeor cellular rubber or the like
IPC: C08J9/36
Filed: 1934-12-06
Abstract: Rubber porous to gases and vapours but impenetrable to a small head of aqueous liquid is made by forming from foamed aqueous emulsions or dispersions of rubber a cellular rubber having cells mainly of relatively small pore size, i.e. sufficiently large as to be visible to the naked eye but not greater than about 1 mm, the aqueous emulsions or dispersions of rubber containing in admixture the requisite quantity, usually about 25 per cent, of the materials specified below which make rubber water repellent. Alternatively if the aqueous emulsions or dispersions do not contain in admixture the requisite quantity of materials to make it water repellent, the cellular unvulcanized rubber is contacted, as by soaking, with the molten or otherwise liquified materials which make rubber water repellent.  The materials which make rubber water repellent are solid water insoluble organic materials which have a high angle of contact with respect to water for example higher alcohols, fatty acids, esters, and paraffins such as ceresin wax, water insoluble solid salts of the higher fatty acids such as zinc and magnesium stearate, and chlorinated compounds such as chlorinated naphthalenes.  The aqueous emulsions or dispersions of rubber may be natural or artificial, vulcanized or not e.g. cencentrates such as those obtained according to Specifications 219,635 and 290,313, [both in Class 70], In order that the cellular rubber may have pores of the desired size the frothing should be carried out until the final bubble size is not greater than about 1 mm. or mixings should be used which favour the formation of small bubbles, e.g. a latex mixing containing zinc oleate.  Emulsions or dispersions which have been converted into a frothy condition according to Specifications 332,525, 332,526, [both in Class 70], and 411,202 may be used. Emulsions or dispersions which are or which can be rendered capable of gelling may be used: in order to avoid coalescence of the bubbles during gelling with production of too large pores the gelling should be sharp, e.g. by using mixes containing zinc oxide or zinc oleate and/or oil or by adding a small amount of sensitizing agent before frothing and the bulk of the sensitizing agent after frothing.  The porous rubber produced according to the invention may be used to coat or impregnate fibrous material such as paper, felt or woven material and the treated material may be used in the production of water-proof garments, shoes, &c.  The products produced according to the invention can be treated with materials for instance soap insolubilizing agents, such as aluminium salt solutions, to enhance their waterproof nature.

IPC: F16C37/00
Filed: 1965-08-18
Abstract: 1,109,518. Bearings; lubricating. WESTLAND AIRCRAFT Ltd. 1 Aug., 1966 [18 Aug., 1965], No. 35515/65. Heading F2A. [Also in Division F1] In a lubricated bearing assembly for a turbounit, a shaft 4, Fig. 1, is mounted in ball bearings 5, 5 which are contained in a carrier 6, supported by walls 7 and 8 of an outer shell 9. The latter contains a lubricant sump 11; a liner 10 which forms a jacket 18 for cooling- fluid; and labyrinth seals 16 and 22 for the carrier 6, the bearings being lubricated by a circulation of lubricant within the carrier 6 and the lubricant being retained therein by pressurized cooling-fluid acting on the outer surfaces of the seals 16 and 22. In operation, pressurized cooling-fluid is passed through an inlet 17 in the shell 9; through the jacket 18 and ports 37; into an annular-space 38 which is formed behind a restrictor-plate 14; through an annular-gap 15, formed between the plate 14 and a rotary-sleeve 32 of the seal 16; into a chamber 26; and out of the unit through ports 27. Some fluid from the inlet of a turbine 2 bleeds through an annular port 33 into a space 20 and then passes through passages 19, into the jacket 18. The pressure differential across the seals 16 and 22 is effected by means of the annular-gap 15 creating a back-pressure in the jacket 18, in the passages 19 and in the space 20, thus providing a pressure on the outer surfaces of the seals; and by means of the inside of the carrier 6 being connected to ambient, via passages 23, 24 and 25 in the shaft 4, the chamber 26 and the ports 27. The bearings 5, 5 are lubricated by mist which is drawn by impellers 36 from wick-loops 31 fed with lubricant by wicks 30 in the sump 11. The lubricant mist passes through the bearings into an annular-space 13, through ports 35, and back to the space between the wick-loops 31. In a modification, the jacket 18 is omitted and the carrier 6 is provided with radial fins 40, Fig. 3, enclosed in a sleeve 41. The fins 40 provide four alternate passages 42 for the cooling-fluid and four alternate passages 43 for the lubricant mist. An axial fan (44), Fig. 2 (not shown), is attached to the shaft 4 and drives cooling-fluid along the passages 42 to the annular-space 38 and then through the gap 15 to the chamber 26 and outlet-ports 27. The lubricant mist drawn from the wick-loops 31 through the bearings by the impellers 36, is delivered through opposite ends of the passages 43 to the radial ports 35 leading back to the interior of the carrier 6.
