In an arrangement for setting and controlling sequentially and automatically, in response to the intensity of light incident on a photo-voltaic diode 10, Fig.5 the aperture 88 and shutter 98 of a camera, the diode is connected to an amplifier 54, having at its input a pair of pushpull super beta transistors, and a feedback loop from the amplifier output to one side of the diode to obtain a predetermined relationship e.g. proportionality. The aperture is set through a threshold detector drive circuit 80, the intensity signal charging a comparitor 82 which stops the aperture drive when its voltage equals the predetermined threshold. When the aperture has been set the amplifier output is gated through inhibit circuit 92 to a record threshold detector driven 94 to energize shutter solenoid 96 and charge over the feedback circuit from linearizing resistor 62 to the path including capacitor 66 whereby the amplifier output is a function of the time integral of the light intensity. The shutter solenoid 96 is deenergized when the output reaches the threshold value. The super-beta gain is required to be in the range 1000-5000 and a full transistor circuit for the arrangement including overvoltage protection for the super-beta transistors is described with reference to Fig.6 (not shown). Silicon or selenium diodes may be used, and a suitable silicon diode comprising a transistor with its base short circuited to its emitter to reject near infrared is described with reference to Fig.2 (not shown). A fitter may be positioned in front of the detector to reject infrared.

Patent GB-105816-A (GB)
IPC: B64C33/02
Abstract: 105,816. Saunt, W. F. May 22, 1916. Propelling; steering.-An aerial machine of the kind described in Specification 14862/15 has (1) means for varying the angle which the inclined extension makes with the main driving-shaft, (2) means for varying the angle of incidence of the wing, and (3) means for varying the opening and closing movement of the wing, all controlled from a single hand-lever capable of three motions. (1) The main driving-shaft B of each wing is supported in bearings E, F and the two shafts have worm-wheels C driven from a common worm D. The extension H working inside the hollow humerus of the wing is pivoted at G and has two arms K, L connected to a cord M which passes into a hollow in the shaft B and over a pulley N. One point of the cord is connected to a pin N<1> passing through a slot in the shaft B to a sleeve 0 adapted to slide on the shaft. The sleeve 0 turns in a sleeve adapted to be moved by a forked lever S so as to vary the inclination of the extension H. Separate sleeves adapted to be moved in opposite directions may be connected to separate cords M instead of forming the cord into a loop, and one of the sleeves may be inside the shaft. (2) The gimbal mounting of the humerus is carried by a ring 1 adapted to turn on a bracket 3 fixed to the body. A rod connects the lower fork of the humerus to an adjustable slide on the body, this arrangement producing an independent cyclical variation of incidence. According to the Provisional Specification, the rod may be connected directly to the ring 1, in which case there is no cyclical variation of incidence. (3) A rod 7 connects an extension of the ulna of the wing to a slide 8, or two cords connected to the ulna at opposite sides of its pivot may be used. The controls (2) and (3) are available when the machine is used as an aeroplane, the shaft H under those circumstances being turned into alinement with the shaft B so that the wing is not affected by rotation of the shaft. The three controls are operated by the lever device shown in Fig. 6. A lever 9 universally jointed at its lower end is connected at 13 to horizontal lateral and longitudinal cords led respectively to the pivoted lever S and slide 8 of controls (1) and (3). A lever 18 having a handle 19 is pivoted to the upper end of the lever 9 and operates a vertical cord 16 led to the adjustable slide of control (2) either directly or through multiplying-gear acting on a leading-screw and nut. The above described controls may be used in conjunction with the tail control described in Specification 102,915.

Patent GB-727311-A (GB)
Title: Improvements in and relating to alternating current welding apparatus
IPC: B23K9/073
Filed: 1950-04-29
Abstract: 727,311. Supply systems for welding arcs. LICENTIA PATENT VERWALTUNGS GES. April 29, 1950 [Oct. 1, 1948], No. 10605/50. Class 38 (4). To improve the stability of an A.C. welding arc, the electrode voltage is temporarily increased on interruption of the arc and after a predetermined interval of time, which may be determined by the operating time of a switch or the time-constant of a resistance-capacity circuit, the voltage is reduced to a safe open circuit value either by the connection of an inductive reactor in shunt with the welding circuit, or by a condenser in series with that circuit. As shown in Fig. 1, an electromagnetic switch 4, responsive to the voltage across the welding circuit and which may be provided with means for artificially increasing its response time, remains unoperated whilst the arc 2 is burning. On interruption of the arc, the welding circuit voltage rises due to the circuit now being unloaded and switch 4 responds, with delay, to connect a reactor 3 across the welding circuit and thus cause a reduction of the circuit voltage. The switch releases when welding recommences. In a modified arrangement the switch 4 controls a D.C. excitation of a saturable reactor permanently connected across the welding circuit. In another arrangement, the arc is supplied through a condenser which is shunted by a resistor.
