Patent GB-495449-A (GB)
IPC: G03B7/00
Abstract: 495,449. Electric control systems. TRUECOLOUR FILM, Ltd., and WHALEN, F. C. May 13, 1937, No. 13494. [Class 40 (i)] [Also in Group XL] The exposure of a camera is timed automatically by means of a photometric device having a narrow field of view, for example, the device described in Specification 472,147, and in which the measurement of the light is determined by the time taken to charge or discharge a condenser, for example, as described in Specification 491,613, the arrangement being characterized in that said photometric device is directed towards the scene to be photographed or towards a reference body adjacent said scene while making the exposure, the shutter being closed when the potential in the condenser has reached a predetermined value. In the apparatus shown diagrammatically for a repeating back camera such as used for colour photography, the operation is started by temporarily opening a switch Sw causing relay R1 to close temporarily to charge the condenser constituted by the capacities of the photoelectric cell P and the connections thereof. The triodes T, V following the cell P thereupon cause relay R2 to close its contacts. This energizes electromagnet 3 (directly or through another relay R3) which opens the camera shutter 2 to start the exposure, When the potential of the cell has fallen to a predetermined value, the relays R2, R3 open, and the shutter 2 closes. The camera carrier 1 is then moved in any known way to the position for the next exposure and the operation repeated. Each time the carrier 1 moves one step, it temporarily closes a switch 4, which starts a motor 5 driving a disc 40 carrying filters 41 between the light and the cell P. As soon as the motor starts spring contacts 6, 7 in parallel with switch 4 close to maintain the motor running ; but when the next filter 41 comes in position, a corresponding cam 8 on the disc opens the contacts 6, 7 to stop the motor and at the same time closes contacts 6, 9 to operate a relay 10, which controls switch Sw and automatically starts the fresh exposure. The filters 41 are chosen so that the cell P has substantially the same sensitivity as the corresponding photographic elements in the carrier. The sensitivity of the cell may be adjusted in correspondence with the camera diaphragm by means of a diaphragm 13 linked to the camera diaphragm, or by a neutral grey wedge, or by a potentiometer additional to the biassing potentiometer 11. Specification 472,174 also is referred to.

Abstract: 1293591 Separating and purifying gases; breather device L V SARADZHEV 28 Oct 1969 52801/69 Headings B1L and B1T A vessel 1, Fig. 1, for storing or transporting substances of high purity, comprises a stopper which acts both as a pressure equalizer and as a purifier for material e.g. gas passing into or out of the vessel, the stopper comprising solid filtering and absorbing materials 17 and 18, and liquid sorbent 5. If the pressure in the vessel 1 decreases, then medium e.g. air from outside the vessel will pass downwardly through filtering and adsorbing materials 17 and 18 and ports 14 and 9 into chamber 6 where any liquid sorbent present will be forced through port 4 into chamber 5, and the air will then itself pass through port 4 and bubble through the liquid sorbent in chamber 5 and then pass via port 8 into the vessel. If the pressure in the vessel increases then the reverse will take place i.e. vapour from vessel 1 will pass through port 8 and force liquid sorbent from chamber 5 through port 4 into chamber 6. The vapour itself will then pass through port 4, bubble through the sorbent in chamber 6, and then pass upwardly through ports 9 and 14 and thence through solid adsorbent and filtering materials 17 and 18 to the atmosphere. Member 16 is a hydrophobic separator. Fig. 10 shows two such arrangements arranged in parallel where the upper arrangement is for drawing off material from the vessel or charging material. The embodiment of Fig. 13 shows the solid and liquid sorbents in co-axial arrangement, and the apparatus is adapted for flushing the internal surface of the vessel with a high purity substance. Suitable materials for the solid and liquid absorbents and filtering materials are aerosol filters, chemical absorbents, and electrostatic sorbents. The solid sorbent and filtering materials may be situated in bags of filtering material. The position of the liquid sorbent in the stopper and/or the direction of flow of gas through the liquid sorbent is an indication of the relationship between pressure inside and outside the vessel.
