Title: Photographic camera
IPC: G03B19/04
Filed: 1970-06-25
Abstract: 1313588 Battery-powered cameras AGFAGEVAERT AG 25 June 1970 [27 June 1969] 30863/70 Heading G2A A camera having an electrically powered element has a battery compartment formed as a sliding drawer 7, which can be opened to insert the battery 11 therein, and which when closed causes the battery terminals to come into contact with terminals inside the camera leading to the said element. In the form shown, the electrically powered element is exposure control means, and the circuit is set out on a printed circuit board 3. This has a U-shaped aperture 4 which can accommodate the drawer-like component 7. Drawer 7 has a circular opening into which fits the battery 11. On the upper and lower faces of board 3 are mounted spring contacts such as 12, 14. (Only the upper one is visible in Fig.1). When drawer 7 is pushed fully home, the spring contacts press against the two poles of the battery, which is thus connected into the circuitry. The board 3 also carries a setting disc 25 which can be adjusted from outside the camera. A slider 28 on the disc can make contact with one of a number of resistances 29-34 which is  connected into the exposure control circuit, and corresponds to a particular flash setting, the appropriate guide number being visible through a window. A pin 37 on disc 25 can engage with an extension 38 on drawer 7, so that continued rotation of disc 25 will push the drawer out of the camera.

Abstract: 166,077. Kliaguine, A. Nov. 2, 1920. Bellows and flexible-diaphragm or flexiblechamber engines; driving-gear.-An internal-combustion or other fluid-pressure engine consists of a flexible chamber, which is expansible radially between two parallel plates, the radial movements being converted into rotary movement by means of cams, cranks, and connecting-rods, or otherwise. The flexible chamber may be corrugated, or consist of plates sliding on one another or hinged together. The space within the chamber may be reduced by means of one or more cores. In an internal-combustion engine, the flexible chamber is formed by plates 3<c> connected by hinged plates 3<d>. The plates 3<c> carry rods 5 sliding in guides 10 carried by the side plates 1, 2, and carrying rollers 6, engaging grooved cams 8, carried by a casing 9, mounted on a shaft 12. The number of undulations of the cam-grooves is varied to give the desired number of revolutions of the casing relatively to the strokes of the flexible chamber, and the grooves may be shaped so that the strokes vary in length and duration. Fluid is supplied to the flexible chamber through a hollow shaft 13 formed with ports 15 co-operating with ports in the hub 16 of the casing 9. An annular portion 1<b> of the side plate 1 is pressed against the edges of the flexible chamber by means of levers 21 acted on by the central portion 1<c> of the side plate. Cooling-air is admitted to the casing 9 by apertures 18 provided with wings 19. Either the casing 9 or the flexible chamber may revolve. In order to equalize wear, the side plates 1, 2 may be rotated slowly relatively to the flexible chamber.

Title: Semiconductor junction devices
Inventor: ANTELL GEORGE RICHARD
IPC: H01L21/316
Filed: 1965-07-21
Abstract: <PICT:1094831/C4-C5/1> A light-emitting diode is made by depositing silicon or a body or layer of P-type gallium arsenide to form a solid layer from which the silicon is subsequently diffused to form a PN junction in the body.  A typical device is formed from an N-type wafer with faces lying in 100 planes by coating one face with zinc-doped silica and after heating to form a diffused PN junction at a depth of 5 m  removing the residual silica and cleaving the wafer along a 110 plane. Another gallium arsenide wafer with parallel edges cleaved along 110 planes is placed on the diffused face of the wafer with the cleaved 110 edges of the two wafers abutting a straight edge. Silicon is then sputtered on to the surface of the diffused wafer not masked by the second wafer and subsequently diffused to form a second PN junction 4 m  from the surface.  After lapping material from the back face, silica is deposited on the diffused face of the wafer and then removed except where the second junction intersects the face.  Electrode layers are provided on the P and N zones and the wafer cleaved along 110 planes into thin strips which are mounted on heat dissipating electrodes 104 as shown in Fig. 10. On forward biasing light emission is concentrated in part 107 of the second junction and can be extinguished by suitably biasing region 101 to effectively short circuit region 109 as in a punch through transistor. In another embodiment (Fig. 5, not shown) which is otherwise basically the same, the silicon is diffused right through a zinc doped layer and the electrode 104 omitted.  Other devices (Figs. 1-3, not shown) simply comprise one or more silicon diffused regions forming PN junctions with a P-type wafer, electrodes being disposed on the diffused regions and wafer proper.
