Patent GB-695283-A (GB)
Title: Improvements relating to apparatus for supplying liquid fuel to continuous combustion turbine engines
Inventor: HARDING JOHN KAMMERER
IPC: F02C7/22
Filed: 1950-06-09
Abstract: 695,283. Gas turbine plant. DOWTY EQUIPMENT, Ltd. June 11, 1951 [June 9, 1950], No. 14490/50. Class 110(iii) [Also in Group XXIX] Apparatus for controlling the fuel supply to the burners of a continuous combustion turbine in relation to the air mass flow, comprises a vent valve 12 controlling a servo device by which the rate of fuel supply is controlled, additional to a vent valve under the direct control of an operator's speed control member (not shown). The valve 12 is carried by a lever 13 pivoted at 14 and subjected at one end to a bellows 15 to which air is supplied from the engine air compressor and is a measure of the air mass flow to the engine, and at its other end to a spring 20 the force of which is varied by an adjustable spring 21 to give a force which is a measure of the fuel flow. Spring 21 is adjustable by a member 22 which controls fuel flow from inlet 23 to outlet 26 and the pressure drop across the member is applied through conduits 29, 30 to the interior and exterior, respectively, of a bellows 28, which operates through a rod 41 a lever 39 pivoted at 40 and loaded by a spring 42. The lever carries a vent valve 36 controlling the pressure in a chamber 33 to which pressure fluid is supplied through an orifice 32a in the member 22. Thus the member 22 will be positioned to maintain the pressure drop constant, and the position of the member and hence the loading of the spring 21 will be a measure of the fuel flow. Fuel escaping past the valve 36 returns to the pump inlet through a passage 38, chamber 17 and passage 19. Bellows 16 is provided to prevent pressure variations in chamber 17 affecting the lever 13. The apparatus will thus provide a constant fuel/air ratio for all engine speeds. In order to increase this ratio above and below a critical speed range throughout which the constant ratio is desirable, a loading lever 44 pivoted at 45 is arranged to load lever 39 when engine speed is either above or below the critical range. Lever 44 is acted on by a spring 43 and a bellows 48 supplied with pressure fluid from an engine-driven centrifuge to provide a force on the lever which is a measure of engine speed. The pressure in the bellows and the spring balance each other throughout the critical range, but below and above the lever 44 will tilt clockwise and anticlockwise, respectively, to engage the lever 39 and thus increase the closing force of vent valve 12 to increase the fuel flow. If desired, the end 46 of lever 44 may be prevented from engaging the lever 39 so that no increase of fuel flow takes place below the critical speed range.

Patent GB-664099-A (GB)
Title: Method and device for spinning molten artificial high molecular weight linear polymeric material
IPC: D01D4/02
Filed: 1949-05-31
Abstract: Molten artificial high molecular weight linear polymeric material is spun by extruding the molten mass under pressure through a conical orifice or orifices widening towards the outlet. The orifices may be formed in a spinneret and may be in axial alignment, each orifice widening conically in the spinning direction and each orifice following the first orifice having a greater mean diameter than the preceeding orifice.  The material to be spun may be produced by polymerization of one component or by copolymerization of two or more components or by polycondensation of two or more components.  They may be polyamides, polyesters, or polyurethanes.  The use of extrusion orifices according to the invention is said to prevent gas bubbles from penetrating into the fibre and to enable spinning to be carried out with a single spinning pump instead of two with a byepass and relief valve, as is customary.  The Specification as open to inspection under Sect. 91 comprises also extrusion devices or spinnerets in which a number of orifices are in axial alignment, each orifice following the first orifice having a greater mean diameter than the preceding orifice, as described in the Specification in its accepted form, but the orifices, instead of widening in the spinning direction, are either cylindrical or converge in the spinning direction.  This subject-matter does not appear in the Specification as accepted.

Title: Hydrothermally stable catalysts of high activity and methods for their preparation
IPC: C10G47/16
Filed: 1967-03-30
Abstract: 1,141,955. Crystalline aluminosilicate catalysts. MOBIL OIL CORP. 30 March, 1967 [30 March, 1966], No. 14577/67. Heading C1A. [Also in Division C5] Hydrothermally stable catalysts of high hydrocarbon conversion activity are prepared by calcining a crystalline ammonium aluminosilicate, having a silica/alumina mol ratio of at least 3, in the presence of rapidly flowing steam and base-exchanging the product of the calcination with an ammonium salt, e.g. NH 4 Cl. The process is particularly applicable to the ammonium form of zeolite Y. The calcination, e.g. at 900-1300 F. for 1À5- 12À5 hours, is believed to cause the formation of lattice aluminium defects and aluminiumcontaining cations, the resulting product being a hydrogen aluminium aluminosilicate: thus, after the base-exchange stage, a hydrogen ammonium alumino-silicate is obtained. Steam throughput may be 700-1000 ml./min. and the partial pressure of water-vapour therein may be greater than 0À3 atm. Preferably, chelation at pH 7-9 is than effected to remove amorphous aluminium - containing material formed during calcination, using an ammonium salt of ethylenediaminotetra-acetic acid, e.g. the diammonium dihydrogen salt. A similar chelation may be carried out in a pretreatment stage to remove amorphous agglomerates present in the channels of the starting material. The base-exchange and chelation steps carried out after the calcination may be reversed in order; ammonium chloride base-exchange may be eliminated if the amount of suitable chelating agent is increased to provide sufficient ammonium ions for exchange with aluminium cations formed by steaming. A finishing heattreatment in a steam-free environment may be employed.
