Title: Improvements in or relating to gas turbine engine control systems
Inventor: RUBBRA ARTHUR ALEXANDER
IPC: F02C9/16
Filed: 1950-07-26
Abstract: 697,014. Linkwork. ROLLS-ROYCE, Ltd. July 20, 1951 [July 26, 1950], No, 18736/50. Class 80 (iii). [Also in Groups XXVI and XXXIII] A gas turbine engine control system comprising a control lever connected by mechanical linkage to a control valve regulating the fuel supply and to the speed selecting device of a speed governor which controls the rotational speed of the engine by adjustment of the load has means, operated in accordance with the ambient atmospheric temperature, connected to said linkage to effect an additional adjustment of the control valve whilst causing substantially no adjustment of the speed selecting device. The pilot's control lever 12 is connected to the arm 10b of a rocking lever 10 through a link 11. A second arm 10c of the lever 10 is connected through linkage 27 to the actuating lever 14a of a datum speed selecting unit 14 of a constant speed airscrew unit and a third arm 10d is connected to the operating lever 15a of the throttle valve 15. The third arm 10d has at its end a boss 10e carrying a pivot pin 16 on which is mounted a cranked lever 17 comprising a pair of arms 17a, 17b which are at right angles to one another. The arm 17a is connected through a link 18 which extends through the boss 10a of the lever 10 to a mechanism 22. This mechanism, which may be electrically operated, has a lever 21 which may be forced to one end or the other of the slot 23 by operation of the switches 24, 25. When the control lever 12 is in the idling position shown the pivot pin 16 is in a position in which it is substantially parallel or makes only a small angle with the link 26 connected to the operating lever 15a of the throttle valve 15. In this position movements of link 18 will cause no substantial axial movement of the link 26 since the end of the arm 17b to which this link is connected moves along a line substantially at right angles to the link 26. When the control lever 12 is in the maximum speed position the pivot pin 16 is moved to a position, Fig. 4, in which it is substantially at right angles or a large angle with the link 26. In this position, movements of the link 18 will cause axial movement of the link 26 since the end of the arm 17b then moves along a line substantially parallel to the link 26. The movements of the link 18 have no effect on the rocking lever 10 and so will not alter the setting of the constant speed unit 14.

Patent GB-387918-A (GB)
Title: An improved process for producing artificial filaments with uniform shrinkage
IPC: F16G1/22
Filed: 1932-07-04
Abstract: Freshly spun artificial silk is dried on perforated or permeable bobbins or spools after covering the outer surfaces of the windings with water-tight, air-impermeable jackets, the drying being effected solely from the interior and progressing from the interior to the outer layers.  The inner and middle layers thus dry and shrink first, allowing the outer layers room within which to shrink as the drying proceeds.  The process may be applied to freshly spun artificial silk after completion of the usual wet treatments such as washing, desulphurizing and bleaching.  To obtain uniform shrinkage it is preferred to respool the dried yarn in such manner that the layers which previously were on the inside of the package become the outer layers of the new package which is moistened and then dried in the same manner as before.  If desired the yarn may be twisted during the rewinding process.  The air- and liquid-tight covering may be a thick wrapping of cloth. Preferably, the yarn is rewound slackly on to the second spool so as to allow the yarn to contract more easily.  Yarn treated by the double drying operation with intermediate respooling is shown to be uniformly and fully shrunk to a similar extent as yarns which have been dried in skeins.  When subsequently tensioned, moistened, and again dried, it shows a small and uniform extension.

Title: Means for measuring or indicating speeds and/or speed changes
IPC: G01P5/17
Filed: 1953-07-09
Abstract: 796,864. Measuring fluid flow. NEEDLE, B. L. June 29, 1954 [July 9, 1953; Nov. 5, 1953], Nos. 19142/53 and 30547/53. Class 69 (1). A pitot tube arrangement particularly for sailing vessels or other craft comprises, a tube 12 with orifice 11 arranged to face the relative fluid flow, a second tube 28 with orifice 30 producing, in the position shown in full lines, a dynamic pressure above the static pressure but less than that produced at orifice 11, a pressure gauge 16 indicating the differential pressure between lines 13 and 27 connected to tubes 12 and 28 respectively, and means adjustable to vary this differential pressure to contain movement of liquid in the pressure gauge within reasonable limits. Tubes 12 and 28 are long enough to contain the change in water level so that lines 13 and 27 contain air only; the pressures in these lines are equalized when the rate of flow is zero (i.e. the vessel is at rest) and movement of piston 35 in cylinder 32 may be used to adjust the level of liquid in the sight glass 17 of gauge 16. By bringing this level back to the scale zero (i.e. the level of liquid 18 in the reservoir) the movement of the piston 35 may be used as a measure of speed. Alternatively the movement of liquid in sight glass 17 may be adjusted by rotation of tube 28 so that orifice 30 takes off a different pressure; in the position shown in broken lines it will take off the static pressure only and greater sensitivity will thus be achieved. The length of tubes 12 and 28 may be reduced by inserting in them expansion chambers which allow the necessary increase in pressures in lines 13 and 27 to be obtained with smaller changes in liquid level in these tubes. Tank 25 prevents any liquid from gauge 16 entering line 27.
