Abstract: 271,135. Tonks, W. H., and Sparks, W. Feb. 15, 1926. Fastenings for doors. - Relates to coin-freed locks of the kind described in Specifications 236,881 and 247,351, which have a member automatically displaced and retained in its displaced position by the closing of the door, so that, when the door is opened, it resumes its outer position, thereby fulfilling certain functions. According to the invention, the displaceable member 17, Fig. 2, which is pivoted but which may be a sliding member as described in the prior Specifications above, has pivoted thereto a pawl 19, which drops in front of the coin-pocket 3 to retain the outside handle in its turned position with the main latch 12 withdrawn, if the handle is accidentally released before the door is opened. When the door is opened, the member 17 assumes the position shown in Fig. 3, and the pawl 19 is raised to release the pocket 3 by engaging a fixed stop 20. The member 17 is displaced by the nose 16 of a member 15 pivoted in a housing 14 in the catch plate 13. The nose 16 is bevelled so that it does not prevent the closing of the door. Coin-slit closing-devices; indicators. - The member 17 has a lug, which co-operates with a coin-slit closing-mechanism as described in Specification 247,351. It carries also a pivoted member 27, which engages under a stud'22 on the indicator plate 23 to hold this in its raised position, so that it is unaffected by operation of the inside handle without opening the door. The plate 23 is raised by a cam 21 on the coin pocket and is retained by a catch 24 engaging a stop 25, until the door is closed, when the member 27 engages under the stud 22 and displaces the catch 24 by engagement with a stud 28 thereon.

The pointer 7 (Figs. 1 and 2) of an electric exposure meter built into a photographic camera is reflected into the field of view of a block form "Albada" finder 1-5 by means of an inclined plane mirror 6 cemented into a slot in the lower portion of the block 3 and a lens 9 arranged in the ray path succeeding the mirror 6 so that a virtual image of the pointer is formed substantially at infinity A follow-up pointer may also be reflected-in by the same means. The lens 9, of substantially rectangular shape, is cemented on the lower part of the plano-convex eye lens 4. In an alternative arrangement (Fig. 3), the inclined mirror 16 is cemented into the side of the central finder block 13 and a side strip 19 of the eye-lens 14 is itself ground so as to image the pointer 17 substantially at infinity as before. In a further modification (Fig. 4), a portion 31 of the central finder block 23 is cut out and the exposed portion 30 of the eyelens 24 here images the pointer at infinity. The portion 30 may be ground to a different radius of curvature to the main portion 240 of the eye-lens. Alternatively, a separate lens element may be cemented on to the surface 30 or on to the surface 32. If a plane block for carrying the finder frame 25 were provided in place of the plano-convex eye lens 24 then the lower portion of the block nearer the eye may be shaped to effect the required imaging (as in Fig. 3). In a further modification (Fig. 7 not shown), the cut-out is provided wholly within the central block and two lens elements are cemented or moulded (e.g. by pressure) on to the two lateral surfaces thereof. In the modification of Fig. 8 a lens element 112 of high refractive index is cemented into a slot in the lower part of . the eye lens 104. Alternatively (Fig. 9 not shown) the lens element may be cemented into a slot in the central finder block.

Title: Thin-film optical circuit devices
IPC: H01S3/063
Filed: 1973-01-30
Abstract: 1415755 Modulating light WESTERN ELECTRIC CO Inc 30 Jan 1973 [2 Feb 1972] 4554/73 Heading H4F [Also in Division G2] A thin film optical device comprising a garnet crystalline material on a substrate, see Division G2, may have adjacent the upper surface of the film a serpentine microcircuit 55, for carrying an electric current for converting the device into an optical switch or modulation device (waveguide mode conversion via the Faraday effect). The microcircuit may be deposited directly on the garnet film, or be spaced therefrom by a dielectric film of lower refractive index, or be deposited on a glass substrate which itself is spaced from the garnet film by an air gap. A second microcircuit may be superimposed on the first, and have a slightly different periodicity, so that optical switching is obtained by diverting the electric current from one circuit to the other. Since in such a case, domain wall movement in the film is small, the magnetizing field for switching is minimized. In Fig. 5 a second microcircuit 57 is provided. If the easy axis of the garnet lies in the plane of the film, a D.C. current is circuit 57 produces a magnetization in an easy axis direction. A microwave current in circuit 55 tends to tilt the magnetization into another easy direction parallel to the optical propagation direction and produce a magnetic-optical coupling that varies with the microwave frequency.
