Abstract: 1,217,632. Exposure control devices. KOMBINAT PENTACON DRESDEN KAMERA-UND KINOWERKE VEB. March 11, 1969, No. 12699/69. Heading G2A. An exposure control device for photographic cameras which automatically sets the exposure time or diaphragm aperture has a means of checking battery voltage. A battery 14 supplies in Schmitt trigger through a switch 15 linked with switches 6, 7 and 16 operated by the camera release A photoresister 9 is positioned behind a diaphragm 17. A red lamp 4 and a green lamp are positioned in the collector circuits of transistors 2 and 1. In operation, to verify whether the exposure time set is longer than 1/30 second with a preset diaphragm aperture, the shutter release is partially depressed to close the switch 15. If the resistance of photoresistor 9 is high the voltage drop across variable resistor 8 is small. The resistor 8 can be set to represent a shorter exposure e. g. 1/50 second. If the lighting conditions demand a shorter exposure than 1/30 second lamp 4 is not lit, since transistor 1 conducts and transistor 2 is blocked due to a higher voltage drop across resistor 8 a Zener diode 3 maintains the threshold value of the Schmitt trigger constant. To check battery voltage resistances 10 and 11 are connected through a switch 7, closed by actuation of the camera release, to the base of transistor 1, such that the green lamp 5 is lit to indicate satisfactory battery voltage and unsatisfactory voltage by the red lamp 4. Further depression of the camera release connects photoresistor 9 to an exposure timing control not shown. In a modification, Fig. 2 (not shown) a single lamp 5 is used to indicate battery voltage and exposure time.

Title: An improved process for making white clouded enamel
Filed: 1936-05-07
Abstract: 455,771. Enamels. KREIDL, I., 5, Sebastian Kohlgasse, Vienna. May 7, 1936, No. 12964. Convention date, Sept. 25, 1935. [Class 56] Relates to the method of making white enamel in which the whiteness is due to the development of small gas bubbles by the decomposition of substances during the fixing process. According to the invention, the whiteness is increased by the addition of compounds of iron, antimony, cerium, uranium, or arsenic, particularly the oxides, to the enamel. The oxide is added in such a small quantity that the total quantity in the enamel does not exceed 1 per cent. For example, 1000 grammes of enamel, 500 grammes of water, 0À25 grammes of benzidine, 4 grammes of uranium oxide, and 100 grammes of clay are ground in the mill and then applied and fired in the usual manner. Examples of other suitable mixtures are given in the Specification. The oxide may be chosen to have a decolourizing action when the substance used for the development of the clouding gas has a colouring action. The method is particularly suitable for use with frits having enhanced colloidal properties produced, for example, by raising the fluorine content.

Abstract: 474,819. Driving sound-reproducing machines. BRITISH OZAPHANE, Ltd., and WENDER, E. J. May 8,1936, No. 13096. [Class 40 (ii)] [Also in Group XX] An automatically-operated, time-controlled, sound - film talking - machine for making announcements at predetermined times or time intervals, is provided with clock-driven electric switch mechanism for setting the machine into operation, and means are provided on the film for stopping the machine after each announcement. In the installation illustrated, an endless film 1 is driven at uniform speed by a motor 11, Fig. 2, past an optical sound-head 2, the output of which is fed to a loudspeaker. The motor is controlled by switches 4, 6, the former of which is closed for a certain period of the day by a cam 5 rotated at half hour-hand speed by clock mechanism and the latter is closed for short periods at any desired intervals of time by cam 7 driven at minute-hand speed. When both switches 4 and 6 are closed, a relay 8 is energized to close contacts 9, 10, whereby the motor 11 is energized and the film driven past the sound-head, a relay 12 being energized simultaneously to complete the soundhead and amplifier circuits. At the end of an announcement, a local thickening or other deformation of the film passes over a roller 14, Fig. 1, to rotate a spring-controlled lever 17 and open a switch 13, thereby breaking the circuit of the relay 8 and bringing the motor to rest. The inertia of the motor is such that the thickened or deformed portion of the film is carried beyond the roller 14 before its motion ceases, in order to reclose the switch 13 so that the machine will operate when next the switches 4, 6, are closed. Instead of utilizing local deformations in the film for operating the switch 13, this latter may be actuated by a further switch having three contacts, one of which is constituted by a conductive insert in the film, adapted to bridge the two other contacts constituted by brushes contacting with the film. A film requiring rewinding after each announcement may be used instead of an endless film moving always in the same direction, and according to the Provisional Specification, sheet, strip, disc, or other records may be employed.
