Title: Improvements in or relating to blades or vanes for fluid flow machines
Inventor: ELLINGER JOHN HENRY
IPC: F01D7/00
Filed: 1968-09-12
Abstract: 1,235,545. Axial-flow fans; jet propulsion plant. ROLLS-ROYCE Ltd. Sept. 15, 1969 [Sept.12, 1968J, No.43367/68. Headings F1C; F1J. A variable camber blade, e.g. for the outlet stator assembly of a ducted fan in a gas turbine engine, comprises a rigid metal spine portion 16 and a thin sheet metal member 17 of hairpin shaped cross-section surrounding the nose of portion 16 to define the forward surfaces of the blade. The member 17 is rigidly attached to the convex flank of portion 16 at 18 but on the concave flank is attached at 19 to actuation means for varying the camber of the member 17. The actuation means comprise radially spaced oil filled bellows 22 embedded in the portion 16 and each connected to member 17 by a spring link 24. To reduce the blade camber, e.g. in an emergency, pressure oil is supplied through line 23 to the bellows 22 so that the latter expand to move the member 17 from the position 26B into the position 26A. The bellows 22 are arranged to operate as compression springs so that should the oil supply fail they automatically return the member 17 to the position 26B. The bellows 22 are assisted by further actuating bellows 25 interposed in the space between the forward flanks of the portion 16 and the internal surface of the member 17 and connected to a supply of compressed air and plastic foam, the latter helping to reduce vibrations within the bellows 25. To stiffen the member 17 the opposite flanks thereof are interconnected by ties 20, 21 passing freely through slots in the portion 16. The ties 20, 21 are nicked at their points of attachment to member 17 so that they tend to hinge at these points rather than bending over their complete length and distorting the surface of member 17. The variable camber arrangement can also be applied to the trailing edge of the blade. In the ducted fan engine, Fig. 1 (not shown), the variable camber blades (15) support a gas generator section (11) within a fan cowling (14).

Title: A circuit arrangement for the supply of current to amplifiers in subscribers' stations
IPC: H04B3/44
Filed: 1960-12-16
Abstract: 917,509. Transistor amplifier circuits. SIEMENS & HALSKE A.G. Dec. 16, 1960 [Dec. 18, 1959], No. 43486/60. Class 40 (6). [Also in Group XXXIX] In a substation circuit wherein a local battery is charged over the line wires (see Group XXXIX) from an exchange battery, an amplifier which derives additional power from the local battery during speech peaks, acts so as to draw more current, e.g. class A working, when the charging voltage increases and so as to draw less current, e.g. class B working, when the charging voltage decreases. The local battery B is charged over the line wires FL from an exchange battery ZB when keys ST1, ST2 are operated by the subscriber at the beginning of a call. A temperature-dependent resistor RW and non-linear resistor Gi2 are connected across the battery and transistors T1, and T2 of an incoming- speech amplifier EV are connected to this network as shown. Full-wave rectifier Gil acts as a low impedance to speech frequencies and serves only to ensure that positive potential is applied to wire c of the charging circuit independently of the polarity of the line wires. If the voltage across wires c, d increases, e.g. due to a fluctuation of exchange battery potential, or decrease of line wire impedance, &c., the emitter-base potential of T1 and T2 increases (base voltage being held substantially constant by the presence of Gi2) so that more current is drawn by the amplifier and consequently the potential drop along the line increases, thus causing the potential across the local battery B to decrease to its working value. Specification 830,818 is referred to.
