Title: Photographic camera
IPC: G03B9/08
Filed: 1968-07-30
Abstract: 1,241,700. Cameras. NIPPON KOGAKU K. K. July 30, 1968 [July 31, 1967], No.36322/68. Heading G2A. A camera has a focal plane shutter, and a focal plane shutter time adjusting mechanism, an interchangeable lens removably mounted thereon, the lens containing a shutter such that upon mounting the inter-changeable lens on the camera body the lens shutter is coupled to a signal member arranged to transmit to the lens shutter the timing of the completion of the opening operation of a front screen of the focal plane shutter, the arrangement being such that in operation the lens shutter is in the closed position immediately before receiving the signal and opens in response to the signal, 'X' contacts are closed to energize a strobo-flash, and the lens shutter and a rear screen of the focal plane shutter are closed after the flash. The invention may be applied to a single lens reflex camera as shown in Figs. 5 and 6.

Patent GB-906071-A (GB)
Title: Improvements in or relating to electric meter testing arrangements
Inventor: LOVEGROVE HENRY JOSEPH
IPC: G01R35/04
Filed: 1957-11-21
Abstract: 906,071. Photo-electric testing of meters. SANGAMO WESTON Ltd. Nov. 21, 1958 [Nov. 21, 1957], No. 36336/57. Addition to 846,086. Class 40 (3). The arrangement of the parent Specification for testing watt-hour meters by comparing impulses generated by the meter under test and by a master meter, and printing the results by means of a member driven by a synchronous meter energized by the impulses from the master meter, is modified by the addition of means for checking the synchronization of the printing member and the master meter and printing additional marks at instants determined by the rotation of the master meter. In Fig. 1 the master meter drives a disc 12 slotted at its periphery to give pulsating outputs from photocells 15, 16 as a result of light from lamps 13, 14. The positions of the photo-cells are such that the two sets of output pulses are displaced by a quarter of a cycle as in the parent Specification. These pulses are fed to bus-bars 18 to which are attached the various meters under test, each with its own printing unit. In each printing unit, the pulses operate a synchronous motor 21 which drives a printing cylinder 23 through two revolutions for each revolution of the meter disc 12. A helical rib 24 on the cylinder makes a mark on paper 27 whenever a bar 25 is pressed down on to it, the distance of the mark from the edge of the paper depending on the angular position of the cylinder. The test meter drives a disc 50 carrying an aperture 53 which cooperates with a lamp 54 and photo-cell 55 to give one pulse per revolution. This pulse energizes an electromagnet 26 to depress the bar 25 and make a mark on the paper, and at the same time by means of a link 29 and ratchet 47 to advance the paper by a given amount. If the master and test meters are running at exactly the same speed, the paper will show a row of dots parallel to its edge, while deviations in the speed of the test meter will cause a deflection of the row as in the parent Specification. If slip occurs in the motor 21, dots will be deflected in the same way and give a false indication. To avoid this, the master meter drives a further disc 30 carrying two reflecting patches 56, 57 not quite diametrically opposite one another. A photo-cell 32 thus energizes a second electromagnet 34 to give two marks side-by-side on the paper adjacent to the dot representing the test meter. In the absence of slip, the lines produced by these dots will be parallel to the edge of the paper, and slip will show up by a deflection or displacement of the lines. Should the motor 21 stop altogether, the two sets of marks produced by electromagnet 34 will be superimposed on one another and appear as one row. The marks on discs 12, 30 and 50 may in general be holes, slots, or light-absorbing or light-reflecting patches. The relation between the speeds of the meters and the cylinder may be different from that shown. The Provisional Specification also refers to Specification 710,351.
