Abstract: 1,233,037. Cameras. PENTACON DRESDEN KAMERA-UND KINOWERKE VEB. Nov.26, 1968, No.56052/68. Heading G2A. In a single lens reflex camera having interchangeable lenses with diaphragms which close to preset values on shutter release, the reading on a through-the-lens light meter is adjusted according to the maximum aperture of the particular lens, by means of a lug on the lens; the camera and its light meter also being usable with lenses not having correction lugs. In Fig.2, a lens 5b has a fixed lug 10b which rotates the casing 2 and thus the needle 4 of a light meter galvanometer, through an arm 9 thereof, a distance corresponding to the maximum aperture of the lens 5b. A lug 17b which presets the diaphragm value, is adjusted, by diaphragm ring 18b until, by means of an arm 16, it has brought a needle 12 into coincidence with the needle 4. A scale 18 indicates the f number to which the aperture will thus be closed. When a lens without lugs 10b, 17b is attached, springs 6, 13 move an arm 14 of needle 12 and an arm 7 of galvanometer 2 into abutment with stops 8, 15. These positions correspond to the maximum diaphragm values. The correct diaphragm value in this case is found by closing the diaphragm until the needle 4 moves into coincidence with needle 12. In an alternative embodiment, Fig.4, a correction lug 28b, corresponding in length to the maximum aperture of a lens 25b, is fixed to an adjustable diaphragm-setting lug 27b. The position of the left-hand end of the lug 28n of any lens 25n, when the lug 27n is set to the maximum aperture of that lens, is the same so that an arm 28 of a needle 26 always abuts a stop 29 initially. The correct exposure is set by adjusting the diaphragm-setting lug 27b until the needle 26 coincides with the galvanometer needle 24. The diaphragm value which has thus been preset may be indicated on a scale by means of levers 31, 32. When a lens without lugs is attached, the arm 28 engages the stop 29 and the diaphragm is closed until the needle 24 is opposite the needle 26. A scale 23 may indicate, for example, exposure times, so that the position of the galvanometer may be adjusted accordingly.

Abstract: 1312637 Battery charging systems INDUSTRIAL INSTRUMENTS Ltd 3 Sept 1971 [4 Sept 1970] 42555/70 Heading H2H A timing circuit for an automatic battery charging system comprises a storage cell B1, a voltage sensitive trigger circuit VT7, VT8 responsive to the cell voltage and a voltage monitoring circuit responsive to the voltage of a main battery to be charged and the monitored voltage thereof being below a first level for charging the cell to a voltage above the threshold of the trigger circuit and for discharging the cell when the monitored voltage reaches a second voltage level V H  so that the cell voltage falls below the threshold of the trigger circuit after a time dependent on the charge delivered to the cell during the charging period. The cell is charged from a 12 volt A.C. source via a bridge rectifier D1-D4 and a voltage regulating circuit including Zener diodes D5, D6 and a stabilizing transistor VT1. The main battery to be charged is connected via contacts (not shown) of a relay RL1 to a charger (not shown) and the voltage of the main battery is supplied to the voltage monitoring circuit which includes a chain of resistors R4, RV1, R5, the resistor RV1 being set to determine the level V H . Initially, assuming the main battery voltage to be relatively low, the transistor VT2 is off and the transistor VT3 is on. The transistors VT3-VT5 are therefore on and the transistor VT6 is off so that the cell B1 is being charged and has a relatively low voltage. The Schmitt trigger VT7, VT8 switches on a transistor VT9 to energize the relay RL1 and enable its contacts to connect a relatively low output voltage from the charger across the main battery. When the cell voltage exceeds the threshold of the Schmitt trigger VT7, VT8, the relay is de-energized and the main battery is charged from a relatively high output voltage of the charger. When the output of the voltage monitor reaches the level V H , the state of the Schmitt trigger TV2, VT3 changes so that the transistor VT6 is switched on and the cell B1 discharges. The main battery continues to be charged from the high voltage supply until the voltage of the cell B1 falls below the threshold of the Schmitt trigger VT7, VT8 whereupon the relay contacts connect the main battery to the relatively low output voltage of the charger. Thus the time for which the high voltage charge is applied to the main battery depends on the time for which the main battery was charged at the initial relatively low voltage.
