Abstract: 378,172. Training aviators. JOHNSON, W. E. P., Central Flying School, Wittering, Wansford, Northamptonshire. July 13, 1931, No. 20085. [Class 4.] A device for training aviators comprises t w o sets of controls so connected to instruments that movement of either control actuates a corresponding instrument which can be restored to normal reading by an opposite movement of the other control. The effect of other than momentary adjustments of the rudder and elevator controls upon a dummy compass and altimeter may also be simulated, and the whole device may be mounted in a fuselage capable of turning about its three principal axes. The Figure shows in plan two control levers 1, 3 and two rudder bars 2, 4 connected by strings to a turn indicator 7, a bank indicator 9 and an airspeed or pitch indicator 11, springs in the string circuits allowing relative movement to take place. Springs 26 connecting the string circuits of the rudder and aileron controls enable the effect of one control upon the function of the other to be simulated. There may be a similar interconnection between the airspeed indicator and throttle and tachometer controls. A compass card 25 is driven by a reversible electromotor 21 controlled by a potentiometer 18 and finger 17 connected to one rudder bar or it may be controlled by the turn indicator 7. The compass may be geared to move more sluggishly on Northern bearings.

Filed: 1964-05-19
Abstract: 1,043,376. Transistor circuits. SOC. INDUSTRIELLE DES NOUVELLES TECHNIQUES RADIOELECTRIQUES ET DE L'ELECTRONIQUE FRANCAISE. May 19, 1964 [May 17, 1963; March 20, 1964], No. 20692/64. Heading H3T. In a high-speed deflection circuit for a cathode-ray tube, a pair of coils 1<SP>1</SP>, 1<SP>11</SP> are driven in push-pull by transistors 21, 2<SP>11</SP>, further transistors 11<SP>1</SP>, 11<SP>11</SP> and diodes 12<SP>1</SP>, 12<SP>11</SP> being arranged to increase the supply voltage to each coil momentarily when the current is increasing in the respective coil. The invention is applicable to systems in which the beam is rapidly displaced from one rest position to another. Transistor 2<SP>1</SP> is preferably driven by a pulse obtained from an amplifier 7<SP>1</SP> via an emitter follower 8<SP>1</SP>, negative feedback being provided at 9<SP>1</SP>. An inverse pulse is derived from the emitter of 2<SP>1</SP> and fed via amplifier 7<SP>11</SP> and emitter follower 8<SP>11</SP> to control transistor 2<SP>11</SP>. Diodes 12<SP>1</SP>, 12<SP>11</SP> normally connect the deflection coils 1<SP>1</SP>, 1<SP>11</SP> to a supply Up, but at the time of each negative-going step in the waveforms fed to 2<SP>1</SP>, 2<SP>11</SP>, a positive-going transient at the respective collector (e.g. c<SP>11</SP>) turns on 11<SP>1</SP>, momentarily connecting the upper end a<SP>1</SP> of coil 1<SP>1</SP> to a higher voltage supply U t . This has the effect of increasing the rise of current and hence increasing the speed of deflection. In Fig. 3 (not shown), further emitter followers (13<SP>1</SP>, 13<SP>11</SP>) are interposed between c<SP>11</SP> and a<SP>1</SP> so as to linearize the deflection.
