Abstract: 1,232,809. Indicating exposure setting in reflex cameras. NIPPON KOGAKU K. K. Aug. 28, 1968 [Aug.28, 1967(3)], No.41090/68. Heading G2A. A reflex camera has a pentaprism view-finder, a scale of exposure values (e.g. f-stops) along one edge of the focusing screen of the prism, a window revealing part only of the scale, and means for producing relative movement between scale and window in accordance with the movement of exposure-setting mechanism on the camera (e.g. a time-setting knob). In the form shown, the focusing screen 4, which is formed with a step 4<SP>1</SP>, is spaced from the condenser lens 22 by a frame member 5. Frame 5 is divided into a large window, corresponding to the picture area, and a small window 5<SP>1</SP> lying above the step portion 4<SP>1</SP> of the screen. Two crossed polarizing plates 6, 7 are located below window 5, along the step portion 4, and one of these plates carries a scale of exposure values, e.g. f -stops. A small plate 8 of an optically active material such as Cellophane (R.T.M.) is fixed to a cord 2, and can be moved along between plates 6 and 7. Plates 6, 7 and 8 together produce the effect of a window, and light will pass through the three plates only at the place occupied by plate 8. Thus only the scale value aligned with plate 8 will be seen in the view-finder. One end of cord 2 is wound on to a spring-loaded spool 1, so that the cord is always urged to the left as seen in Fig. 2. The other end of the cord winds on to a reel 3 mounted on a shaft 11, the shaft being driven from a gear wheel 10 coupled to the aperture-setting knob of the camera. Thus as this knob is turned to adjust the aperature, the corresponding f -value (and only this value) is seen in the view-finder. Figs. 4-6 (not shown) represent another embodiment in which, instead of the window moving with respect to the scale, the scale moves with respect to the window. In this case the window is fixed opening (106), and the scale is marked on a strip (116) which can be moved under the window. Figs. 7-9 (not shown) represent a third embodiment in which light is reflected through the scale from a small auxiliary mirror (52).

Abstract: 1,265,780. Matrix memory circuits. INTERNATIONAL BUSINESS MACHINES CORP. 18 Dec., 1970 [30 Dec., 1969], No. 60210/70. Heading G4C. A data processing system, e.g. a bi-stable matrix memory, comprises a number of groups of circuits each circuit having a substantially constant current flow, connected in series with a voltage source, and a means for applying data signals to and receiving data signals from the groups of circuits in parallel. A bi-stable matrix memory is described in which each matrix plane 10 stores corresponding bits of each word stored in the memory. The planes are all connected in series with the voltage power supply 20 and a shunt regulator 22 is connected in parallel across each plane in order to compensate for any small changes, which should be less than 10%, in the current flow which may occur, e.g. when a bi-stable is switched. The planes are connected in parallel to the addressing and data input/output lines 26A, 28A and 42A, 44A, 46C, 48C via optically coupled semi-conductor diodes 39, 41 which ensure that the voltages on the input/output lines are independent of the voltage levels on individual boards which are different due to the series arrangement. The arrangement reduces the current which the supply cables have to carry. To prevent overly large voltages from occurring the number of groups of circuits which are connected in series is restricted and larger systems are divided into smaller units. The Specification states that the invention may be used in connection with other memories or data processing systems provided only that each circuit draws substantially constant current at all times. Electro-optical coupling between the memory planes 10 for logic and shifting operations is mentioned.
