Title: Electric wave amplifiers of the negative feedback type
IPC: H04B3/08
Filed: 1942-05-01
Abstract: 554,214. Repeater systems. STANDARD TELEPHONES & CABLES, Ltd. May 1, 1942, No. 5889. Convention date, Feb. 25, 1941. [Class 40 (iv)] [Also in Group XL] In a negative feedback amplifier for signal and pilot currents applied to the input and feeding an output circuit, selective means are provided in the amplifier to divert pilot frequency current to an auxiliary load and introduce greater loss at this frequency than at the signal frequency. Fig. 4 shows a series network tuned to the pilot frequency, from the inductance 16 of which pilot frequency energy is withdrawn by the coupled coil 14 to an output circuit p<SP>1</SP>. In a modification the pilot frequency is withdrawn through a tuned acceptor circuit arranged in shunt to the valve, Fig. 2 (not shown), and if matching of the output impedance is necessary a similar tuned acceptor circuit may be connected across the outputtransformer primary. Fig. 5 shows a threestage amplifier in which a network 26 provides positive feedback at the pilot frequency to maintain the gain at the pilot frequency if the overall amplification round the negative feedback loop is insufficient to prevent an abrupt variation in gain of the normal amplifier path at the pilot frequency. As shown, the pilot current is utilized to control flat gain and slope control circuits 32, 33 through thermistors 51, 52, and the output and feedback voltages are taken from an output bridge in which a T- section 54, 55, 56 is used to avoid an undesirably high value of resistance for the arm XW. Magnification of the current changes due to the pilot current is produced by the directly heated thermistors 57, 58 and the resistance 59. Supplemental heating may be provided for the thermistors to compensate for changes in ambient temperature. The pilot power may be diverted at a stage in the amplifier anterior to the output stage, Fig. 3 (not shown), to increase the power margin in the latter stage.

Title: Improvements in or relating to gyroscopic control devices for dirigible objects such as aeroplanes
IPC: G01C19/00
Filed: 1934-02-23
Abstract: 579,460. Gyroscopic apparatus. MEREDITH, F. W., and MYLES, J. (Representative of MYLES, J.). Feb. 23, 1934, No.. 5999. [Class 97 (iii)] [Also in Group XXIX] The rolling movement of an aeroplane &c. is controlled by a universally mounted gyroscope with the rotor lying horizontally and athwartship, and means sensitive to that component of acceleration which is normal to the plane of symmetry of the aeroplane produces a torque about a substantially vertical axis so as to precess the gyroscope about a fore-and-aft axis. When the aeroplane rolls in straight flight, the outer gimbal ring 4 of the gyroscope is displaced from the vertical and the contra gravitational acceleration acting on a single or double mass 8 connected to the ring either directly or through links and levers displaces the ring and actuates a piston valve 9'through a link 10. The valve admits compressed air to one side or the other of a piston 13 connected to the inner gimbal ring 3 in'order to process the gyroscope. The cylinder and piston 13 is adjustable in position so that the component torques applied to the gyroscope can be varied when the mean pitch attitude and/or speed of the aeroplane are varied. Movement of the inner gimbal ring 3, through a link 16, actuates a piston valve 18 controlling a piston 23 connected to the aileron. A follow-up action is provided by a bell-crank 25 connected between the rod of the piston 23 and the cylinder of the valve 18, or the frame 7 may be pivoted and connected to the rod of the piston 23. During turns, centrifugal accleration causes the mass 8 to exert a torque on the:ring4 4 and the aeroplane will be kept level laterally, as in straight flight. The frame 7 in which the outer gimbal ring is pivoted may be pivoted about the fore-and-aft axis of the aeroplane to permit adjustment of the lateral level to give a desired amount of bank during turns.

Abstract: 1,261,887. Change-speed control. S.R.M. HYDROMEKANIK AB. 29 Jan., 1969 [7 Feb., 1968], No. 6062/68. Heading F2D. A control-valve for a vehicle mechanical or hydraulic transmission, providing a positive neutral and direct-drive release in accelerator released and fully depressed (kickdown) positions respectively, is arranged in the linkage between the accelerator pedal and the engine throttle or injection pump, and is thereby rendered independent of vehicle cabin movement or dimensional changes in the throttle linkage, and is capable of being pre-set before assembly in the linkage. Connected in the linkage at the accelerator side is a plunger 30 slidable in a body 32 connected therein at the throttle or injection pump side to form a collapsible link. In the idle position a light spring 34, lighter than the pedal return spring, expands the link so that a projection 44 on the plunger 30 opens a spring-closed valve 48 to supply compressed air from an inlet port 54 through a passage 56 and side delivery port to a connection establishing positive neutral in the transmission in which the torque-converted reactor is released, thus reducing creep tendency. On initial depression of the accelerator pedal (position shown) the projection releases the valve 48 for closure, to vent the neutralizing line at 52, this condition persisting unchanged throughout the remainder of the pedal stroke until it reaches detent position at full throttle, whereupon further movement to kickdown overcomes a stronger spring 36 and the projection 44 opens a second valve 58 supplying compressed air through a connection 16 to release direct-drive in the transmission and provide additional torque. The side ports are connected to supply and delivery through flexible pipes bent to V shape, linkage movement being along one leg of the V. In Figs. 4-6 (not shown) the two valves are combined in a single multi-landed axial spool valve having a lost-motion connection with the plunger and sliding between ports sealed by O- rings, whilst in Figs. 7 and 8, (not shown), such a valve acts as pilot for a pair of servo valves controlling passages of larger area.
