For P type devices combinations of Ge, Si, Te, CdTe, GaAs or InSb may be used. Fig. 2 shows the way in which photo-response varies with bias voltage V, it being seen that the photovoltage changes sign in part of the sensitive spectrum for sufficiently high biases. The presence of a rectifier in the photo-diode output circuit results in detection of incident light within a specified wavelength range determined in part by the bias voltage. The D.C. bias voltage may be replaced by a sawtooth waveform, in which case periodic sampling of the rectified photo-voltage permits detection of light of a plurality of wavelengths. Fig. 7 illustrates an arrangement in which two N type ZnSe-Si heterojunction photo-diodes provided with In electrodes 20, 30 are supplied with D.C. biases of equal magnitudes but opposite polarities. By providing rectifiers 23, 33 in opposite senses in the two outputs it is possible to distinguish between incident radiations in different wavelength ranges.

Abstract: 1298827 Coil winding apparatus BALZER & DROLL KG 11 Dec 1969 [17 April 1969] 60606/69 Heading B3A Coil winding apparatus comprises, a coil winding former through which axially extends a set of transfer bars 6, means for receiving a coil from the former and inserting it into the grooves of a stator, the former being positionable in a transfer position wherein the bars 6 are generally parallel to mounting fingers 7 of the inserting means and wherein the bars 6 protrude axially from the former so that a wound coil can be moved along the bars and on to the fingers 7. The apparatus includes two stepped formers 1, 2, which are mounted on a base-plate 22. After winding is completed, the base-plate is pivoted on a shaft 3 to bring the formers into alignment with the inserting device. The bars 6 are then advanced to overlap the fingers 7 and the coils are slid off the formers on to the fingers after moving together the halves of the formers. The winding pitch is adjustable so that the turns do not cross over on the formers by axial movement of a winding device 28 via an hydraulic cylinder 27. A generator 9, driven by the device 28, modulates the output of a power source 11 and the modulated current passes through an amplifier 12 to a motor 13. This motor is coupled to a shaft 14, the angular position of which determines the setting of a pressure regulator 15 to control the pressure in the cylinder 27. Devices 16 provide further control and vary the feed for each of the steps of the formers.

Abstract: 1300080 Elastic spacer for conductors A SALVI & C SpA 30 Dec 1969 [22 Feb 1969] 63374/69 Heading H2C In an elastic spacer, the conductors 1 are anchored to clamps 2, hinged to intermediate rigid bodies 3, which are in turn hinged to a central rigid body 5. The hinges 4, 6 are preferably of wire rope, of length 20 to 50 mm. and diameter 10 to 15 mm. but may be made of a plurality of parallel wire ropes.

Patent GB-784100-A (GB)
IPC: F41A9/30
Abstract: 784,100. Cartridge feed mechanism. BREVETS AERO-MECANIQUES SOC. ANON. May 12, 1955 [May 25, 1954], No. 13753/55. Class 92 Relates to cartridge feed mechanism for automatic guns, of the kind in which a toothed rotor is rotated through an angle at the firing of each round, such movement causing the cartridges to be successively pulled away from the resilient holding strips of the belt or the like. According to the invention each movement of the rotor takes place uninterruptedly through a full pitch angle, the rounds a, b, c, being subsequently thrust laterally towards the breech-block 3 by spring-urged members 40 whose spring 41 is tensioned during at least the end portion of each movement of the rotor 34. In the construction shown the gun recoils beneath a stationary magazine 9 thus causing a cam 13 on the gun to produce movements of a spring-controlled rack 17. The rack meshes with teeth on a sleeve 22 which is connected, via free wheel 23, 25, dog clutch 28, 29, hollow shaft 31, and torsion bar 32, to a tubular shaft 33 carrying the toothed wheels 34 for engaging and driving the cartridge belt. By this means a cartridge such as b, Fig. 4, is advanced at each recoil from the position shown to a point above the passage 38. During this uninterrupted movement the cartridge engages a face of the members 40 and swings the latter against the action of springs 41. The cartridge a in the waiting position is not influenced during this movement, but is subsequently pushed downwards against the breech block by the springs 41 acting through the members 40 on the cartridge b. The spring urges the cartridges a, b downwards suddenly when the breech block moves sufficiently to the rear. A further spring-controlled lever is associated with each member 40 and is engaged by a cartridge-the cartridge b of Fig. 4-towards the end of each movement of the wheels 34 to provide a braking action. Specification 696,350 is referred to.
