Title: Improvements in or relating to apparatus for reproducing sound recorded on photographic sound films
IPC: G11B7/00
Filed: 1933-05-02
Abstract: 405,496. Optical sound-reproducing apparatus. SOC. POUR L'EXPLOITATION DES BREVETS A. G. 1., 88, Rue des Dames, Paris. May 2, 1933, No. 12812. Convention date, Sept. 15, 1932. [Class 40 (ii).] Relates to soundreproducing apparatus of the kind having a reducing optical system cooperating with a slit through which light rays are projected on to the sound track on a film record. According to the invention, the position of the pencil of light rays is adjustable transversely of the sound track by providing a rotatable cap having a single opening, which is so formed and arranged that by rotating the cap the effective length of the slit may be varied, whilst remaining of substantially constant length. Fig. 1 shows one construction, in which a tube 1 carries at one end a lens system within a mounting 2, and at the other end is fitted with members forming a slit 4. The slit is covered by a rotatable cap 6, which encloses a lens 8, and which has an eccentrically formed opening 9. The position of the effective length of the slit 4 is determined by the opening 9 and is varied by rotating the cap. A portion of the opening 9 is slightly overlapped by a flange 10, this formation serving to maintain the effective length of the slit more nearly constant as the cap is rotated. In a modification, instead of being circular, the opening in the cap is formed as shown in Fig. 4. The overlapping flange is dispensed with in this case. The dotted lines intersecting a common point represent the portions of the slit (all of substantially the same length) exposed by the aperture as the cap is rotated.

Filed: 1959-04-16
Abstract: 869,942. Electric selective signalling systems. BELL & GOSSETT CO. April 16, 1959, No. 12975/59. Class 40 (1). In an electric selective calling system in which any one of a plurality of remote field stations is selectively called by the transmission, from a central station, of a sequence of characters, each character is represented by the successively transmitted frequency significant electric signals, the frequency of the first signal belonging to a first set of frequencies and that of the second to a second set of frequencies, all the frequencies of the two sets being different from each other. As described a selected field station is called by setting up a five-digit call sign on five switches 36, Fig. 1. The digits are then transmitted by radio or land-line successively by a distributer 40, each digit being represented by a first frequency of either # 1  or # 2 , followed by a second frequency of one of # 3  to # 7 . At a field station the individual frequencies are routed to corresponding leads by resonant vibrating read filters and the reception of each signal, whatever its frequency, attempts to advance a stepping switch. However, the stepping switches at the various field stations are so connected that unless the signals arrive in the correct sequence of frequencies the advance of the stepping switch is inhibited and the switch returns to its home position. Once a field station has been selected any one of ten switches thereat can be selected by the transmission, from the central station, of a further character and the selected switch can then be opened or closed by the presence or absence of a control signal of frequency # 8 .
