Title: Exposure indicator for SLR camera with electronic shutter - uses a digital viewfinder display for auto or manual selection
Inventor: TAKAHASHI AKIRA
IPC: G03B17/20
Filed: 1974-08-09
Abstract: The camera is fitted with an auto to manual changeover switch for the exposure timing. The analogue values of the times are converted to digital and then used for the luminescent display and conversion into shutter timing impulses. When a shutter time is selected manually, the analogues of this and the meter signal are compared. Any differences in signal magnitudes are used to modify the indicator display so that this shows the manually selected time and the extent, if any, of probable over or under exposure. The discrepancy is shown by intermittent blining at variable speeds or selective illumination of the digits. The design is claimed to be simple to use and to increase camera versatility.

Title: Short circuit protection of DC power supply - uses two complementary transistors in load circuit
Inventor: BRIEGER GUENTHER
IPC: H02H3/087
Filed: 1975-06-26
Abstract: A short circuit protection system is for d.c. power supplies typically for electronic apparatus. Connected to the base of the main transistor (T1) in series with the load (14) is the collector of a second complementary, transistor (T2), with its base connected to an auxiliary supply, and emitter connected to the common rail (11). The base of this transistor is connected, via a blocking diode (D2) to the load and main transistor interconnection. In normal operation (T2) is conducting which drops the base of (T1) to the common rail potential. It therefore turns on, and the full supply voltage is developed across the load (14). The diode (D2) is reverse biased and blocks. If the load becomes short circuited the cathode of diode (D2) is effectively at zero potential (11) and it conducts. This drops the voltage on the base of (T2) to zero and it turns off with consequent turn of of (T1). The circuit remains blocked for as long as the fault is allowed to persist.

Title: Control and shutdown rods for pebble-bed reactor - having arrowhead tips to loosen bed spheres during withdrawal
Inventor: RAUSCH WILFRIED DR
IPC: F02B1/04
Filed: 1976-02-18
Abstract: Device comprises generally cylindrical rods of absorber material with tapering points, which are lowered vertically into the pebble-bed core. The lower part of each rod is so shaped that, when it is withdrawn, some of the spherical elements of the bed are raised, thus causing the bed to be loosened. Pref. lateral projections at >=1 points near the tip of the rod considerably increase its cross-section. This general arrowhead shape is interrupted by vertical slits to permit free passage of vertical guide elements for the rods. In a variant, other parts of the rod may comprise indentations at >=1 points, in which spherical elements tend to become lifted as the rod is withdrawn. Device is used for a pebble-bed reactor, which repeated movement of the control and shut-down rods would otherwise result in compaction of the bed. The use of a head of this type enables the bed to be repeatedly loosened in a simple manner, thus preventing irreversible compaction.
