Title: Improvements in or relating to fuel systems for gas turbine engines
Inventor: SAVILLE HAROLD
IPC: F02C7/22
Filed: 1958-08-28
Abstract: 866,721. Centrifugal governors. BRISTOL SIDDELEY ENGINES Ltd. Aug. 27, 1959 [Aug. 28, 1958; May 26, 1959], No. 27585/58. Class 57. A centrifugal governor 9 for controlling the fuel supply valve 1 of a gas turbine is loaded by a variable spring means 14, 15 arranged to act on the valve in opposition to the governor, the effective rate of the spring means being automatically adjustable in response to the engine throttle setting in order to maintain the sensitivity of the governor substantially constant, or otherwise controlled, throughout its operating range. As shown in Fig. 1, the governor 9 acts through a pin 8 against a lever 7 connected to a pivoted lever 4 on which the valve 1 is mounted, the governor being loaded by two springs 14, 15 acting against the lever 7 through a pivoted arm 10. The springs are connected by levers 16, 17 to cam plates 20, 21 keyed to a common shaft 22 (Fig. 1 shows the cam plates spaced apart for clarity) connected through a linkage 23 to the throttle control lever. When the throttle control is moved between maximum and minimum settings defined by stops 24, 25, the cams are rotated and so move the springs around the curved arm 10, the desired loading on the springs being determined by the shape of the cams. A locking device 29, 30, 31, 33, responsive to change of atmospheric pressure, is provided for overriding the throttle control means to prevent the reduction of engine speed selected by the throttle control means falling below a minimum value required to maintain adequate combustion under the conditions of altitude and forward speed to which the device is responsive; the locking device is coupled to the shaft 22 by a lever 28 and prevents the valve from being closed beyond a certain minimum value irrespective, of the action of the governor, and a slip-coupling device 26 is provided in the throttle control 23. In the modification shown in Fig. 2, a single spring 49 is moved around a curved lever 48 by a linkage 54, 55 which replaces the cams 20, 21 and is coupled to the throttle linkage 51, 52, 53; a stationary spring 56 acts continuously on the lever 48 in order to ensure that the desired sensitivity is obtained in the idling position. A locking device 60, 61, 69, responsive to changes of atmospheric pressure, acts through a rod 70 on the arm.43 to hold the valve half open. A weak spring may be provided between the throttle linkage and the housing to take up backlash. Specification. 866,722 is referred to.

Abstract: 930,653. Semi-conductor devices. SIEMENSSCHUCKERTWERKE A.G. Aug. 12, 1959 [Aug. 12, 1958], No. 27638/59. Class 37. A semi-conductor device, such as a Ge or Si rectifier or transistor, is mounted on a metal plate which is fitted into an open end of a hollow housing, and a second metal plate fixed to and parallel to the first plate, is joined to said open end of the housing by electrical butt-welding, the first plate being of such shape and dimensions that it co-operates with the inner surface of the housing during assembly to guide the parts into the desired positions. As shown, a cylindrical metallic tube 1, into one end of which a metal tube 15 is sealed by means of a glass member 2, is seated in a recess 4a in a jig 4 of insulating material, and a metal cover member 6, which comprises an upstanding disc 6a and a boss 7 on which is mounted a semi-conductor element 8, e.g. a Si rectifier, is applied to the open end of the tube 1, the periphery 1d of which is bevelled, the disc 6a being aclose fit within the neck of tube 1. A tongs-like welding electrode 5 surrounds the part of tube 1 above the jig 4, and a second welding appliance 11 bears down on the cover member 6, a pin 10 thereon, which may be formed with a bore, being received in a recess 12. A gas, e.g. nitrogen, is supplied to the tube 1 via a duct 13 in the jig 4 and the tube 15 before the welding operation, during which the cover 6 is pressed down on to tube 1, the bevelled periphery of which becomes flattened. Finally, the tube 15, which accommodates a lead 9 from the element 8, is squeezed inwards and sealingly welded by electrodes 16, 17. The bevelling of the periphery of tube 1 may be omitted. Specification 930,654 is referred to.

Title: Improvements relating to foamed aliphatic thermoplastic resin products
Inventor: GILBERT JOHN HAROLD
IPC: C08J9/34
Filed: 1964-07-09
Abstract: An extruded, foamed aliphatic thermoplastic resin comprises a mass of substantially parallel elongated cells enclosed by a surface skin, the cells being orientated substantially at right-angles to the surface skin.  The blowing agent is preferably a normally gaseous substance, e.g. a butane.  The foamable composition preferably contains a nucleating agent, e.g. finely-divided silica.  The product may be produced by extruding the foamable resin composition through a die orifice into a zone of lower pressure defined by stationary surfaces that are cooled so as to solidify the resin in contact with them and are spaced progressively further apart from each other along the direction of extrusion such that foaming of the resin occurs as it moves through the zone.  Preferably there is a "step" between the die orifice and the apex of the stationary surfaces.

Title: Separation of ethers from distillation residues of synthetic alcohols
Inventor: DEAN FRED
IPC: C07C27/22
Filed: 1962-07-27
Abstract: Ethers are separated from the high-boiling residues remaining after distilling off the desired alcohol(s) from a product of the carbonylation of olefines by submitting the high-boiling residues to azeotropic distillation with a glycol whereby the ethers distil over with the glycol.  In an example, the residue obtained by distilling crude iso-octanol from the product of the carbonylation of heptenes is distilled, using a boiler and a fractionating column, in order to completely remove iso-octanol.  The still-head temperature at this stage is 225 DEG  C. Propylene glycol is then added to the boiler, and the distillation is continued.  The ether/propylene glycol distillate is cooled, and allowed to separate, in a decanter, into a ether-rich layer and a glycol rich layer.  The latter is returned directly to the boiler.  The ether layer is washed with water and separated; the ethers so obtained boiled within the range 236-281 DEG C.  The residual liquid remaining in the boiler is distilled to remove propylene glycol and recover a product consisting mainly of higher alcohols which can be satisfactorily oxidized to acids by means of fused caustic soda.
