Title: Photographic cameras
IPC: G03B9/64
Filed: 1975-02-17
Abstract: 1486667 Cameras SEIKO KOKI KK 17 Feb 1975 [18 Feb 1974] 6610/75 HeadingG2A A camera has a counter 8 which prior to exposure counts a number of pulses dependant on subject brightness and memorizes the count, exposure time being subsequently controlled in accordance with the memorized count; the counter also being useable as a self-timer to delay the start of the memorizing count, e.g. by 9 seconds. As shown, when self-timer switch SW4 is closed an electromagnet M2 is energized to lock the reflex mirror in the viewing position. On pressing the release, standard frequency pulses from a generator 4 pass through gates 10-4, 10-5, through all the stages of a frequency divider 7 and then through a circuit 13 to the counter 8. After 8 seconds stage 8-13 inverts and this turns on an L.E.D. 19-3 to warn the user that only one second remains. After 9 seconds both stages 8-10 and 8-13 are at "1 " so an AND gate 105 inverts to "1", an OR 14 to "O", a NAND 1-7 to "1" and thus an output E3 becomes "O". E3 turns off LED 19-3 and generator 4, energizes an electromagnet M1 to hold the shutter closing curtain, resets counter 8 and divider 7 and starts generator 4 again. Pulses are counted by counter 8 for the duration of a brightness representative pulse from a generator 5, the count attained also depending on film speed and aperture by selecting one of terminals 9-1 to 9-17. At the end of the brightness pulse, or when the last counter stage is reached the count is stopped, displayed as a shutter speed (see Fig. 4 not shown) the electromagnet M2 is de-energized to release the mirror and open the shutter, a timing switch SW3 is opened, the shutter speed indicator is turned off, subtractive pulses are fed to counter 8 and when the count reaches zero a detector circuit 16 de-energizes electromagnet M1 to close the shutter. Mention is also made of counting for a fixed period pulses whose frequency depends on subject brightness. The self timer can also be used when an exposure time is manually set by selecting one of terminals 9-1 to 9-18 to pre-set a count. After 9 seconds pulses from generator 4 are fed to counter 8 until the pre-set count is reached whereupon a detector circuit 17 de-energizes M1 to close the shutter. The specification also describes the use of the circuit without the self timer with means for limiting the counting period if illumination is low, (see Specification 1479705).

Title: Improvements in packaging
IPC: B65B11/54
Filed: 1940-04-16
Abstract: 540.606. Packaging, WINGFOOT CORPORATION. April 16, 1940, No. 6867. Convention date, Aug. 2, 1939. [Class 94 (i)] Relates to a method of packaging substances in a film of material which is rendered stretchable and self-sealing by heat, and consists in shaping the heated film by fluid pressure, enclosing in the shaped film the substance to be packed, and allowing the film to contract while warm or causing it to contract by the application of heat. Preferably the film is made of rubber hydrochloride, but vinyl derivatives may be used. The film 2. Fig. 1, may be shaped by spreading it over the mouth of a chamber 1, and clamping it in place by a ring 3. The film is then warmed and is stretched, to conform to the inner wall of the chamber, either by directing an air jet against its outer surface or by applying suction to the interior of the chamber. When the required amount of substance has been placed in the stretched film, the edges may be gathered up and twisted, as shown in Fig. 3, preferably by twisting the chamber 1 while the film is held stationary by the ring 3. The twisting causes coalescence of the heated film to produce an air-tight seal 6. !Granular or liquid materials may be packed by pouring the material into the stretched film, or liquid or pasty material may be forced from a nozzle to stretch and shape the film. Specification 533,502 is referred to.
