Title: Improved photographic machine
IPC: G03B19/04
Filed: 1922-03-23
Abstract: 177,537. Zollinger, E. March 24, 1921, [Convention date]. Void [Published under Sect. 91 of the Act]. Cameras, roll and film and collapsable, and cases for; roll-spools.-In a roll-film camera, the lens 9, Fig. 4, is mounted on a slotted focusing mount moving in an inner frame 7 of the casing 1. The casing is stamped out cf sheet metal and shaped to contain the spools 6, and is closed by a cover 2, Fig. 2. The slot 13 of the focusing mount is specially cut so that the distance graduations on the plate 27 may be equidistant. An extension slot 14 is provided so that, with longfocus lenses, the lens mount may be pushed right into the frame 7. The exposure indications are obtained by means of a wheel 16, Fig. 1, rotating in contact with the edge of the film and driving an indicating pointer. Three alternative constructions of indicating mechanism are described. The film may pass over a padded plate 23, or, to facilitate loading, a retractable spring plate may be fitted to press the film forward against the frame 7 and the operative wheel of the indicator. The backing paper of the film may be dispensed with and the film formed with extensions 29, Fig. 8, which have gaps 30. The absence of movement of the indicator indicates that these gaps 30 are passing the wheel 16 and indicates the starting and end of the film.

Title: Improved manufacture of resilient joints
IPC: F16D3/76
Filed: 1931-03-19
Abstract: 369,392. Flexible-unjointed hinges. HOUDAILLE, M., 50, Rue Raspail, and LECLER, C., 3, Rue Trezel, both in Levallois- Perret, Seine, France. March 19, 1931, No. 8511. Convention date, March 21, 1930. [Class 65 (ii).] In a joint comprising sockets between which is interposed a mass of resilient material such as rubber, surfaces of discontinuity are provided in the resilient material in such a manner that any relative movement of the sockets produces not only molecular distortion but also a propping or clamping action between the adjacent parts at these surfaces, so as to increase the compression, and therefore the adherence to the members, of the resilient material. The joint may be constructed so that.the stress in the rubber is not uniform, to allow of oscillation in the plane of the axis without slipping ; in this case surfaces of discontinuity are not essential. The mass of rubber may be formed of a spiral or helical strip of any section wound on the inner joint member, or of a block having a helical cut or a number of radial cuts, which mav or may not extend through the whole thickness of the rubber ; alternatively, a number of similar parts of cylindrical or other suitable form may be fitted together to form the rubber block. A longitudinal rib may be provided on the rubber to engage each or either joint element. The adjacent parts at the surfaces of discontinuity may be separated by independent strips of resilient material. Two of these joints may be used in combination, a single rubber strip being used to form both resilient members, as in Fig. 18. The joint members and the mass of rubber may be of different shapes before assembly, Fig. 20, or one of the joint members may be distorted after assembly, so that the rubber is stressed more highly at the centre of the bearing than at the ends, to allow of oscillation in the plane of the axis without slipping.

[Also in Division C7] A scribe material (i.e. sheet material part of the depth of which can be removed by manual incizing with a sharp tool to give a relief effect) includes a support layer, a scribe layer (i.e. a uniform pigmented layer of which a part can be readily removed by scribing to give a clean relief effect), a deposited thin metal layer which is at least thick enough to increase the actiric density of the scribe material but not thick enough to inhibit clean scribing, the scribe layer being between the other layers, and a photo-sensitive layer may be provided on the metal layer, which on exposure provides images which can be used as a guide in scribing. There may be scribe, metal and photosensitive layers on both sides of the support layer. The support layer may be cellulose acetate, polyacrylate, polycarbonate, polyethylene, polyester, polypropylene, polyethylene terephthalate, laminates with phenol-formaldehyde resin, or glass, and may be transparent or not, and preferably 0À002-0À04 inches thick. The scribe layer may for example comprise 2 parts by weight an alkali-soluble alkyd resin, 9 parts titanium dioxide, 0À016 parts cobalt naphthenate drier and 9 parts solvent such as xylol, toluol or ethyl acetate. Coloured pigments, such as chrome yellow molybdate orange, carbon black may be used, or dyes may be added. There may also be added, up to 10% of the resin content, urea and melamine formaldehyde resin, and nitrocellulose up to 75% of resin content if plasticizers are also added. The metal layer may be aluminium, chromium, copper, nickel, gold, silver or other metal deposited by evaporation, sputtering, chemical deposition or electrolytically. If the scribe material is translucent, scribing can be carried out on an illuminated table. One method of scribing is by cutting the image in outline and stripping away the scribe layer within the outline, which method is used for lithography and map-making. Printed circuits for test boards can be laid out by removing part of the metal layer, leaving metallic conductive lines.
