Abstract: 475,551. Optical sound-reproducing apparatus. I. G. FARBENINDUSTRIE AKT.-GES. May 18, 1936, No. 14046. Convention date, May 18, 1935. [Class 40 (ii)] [Also in Group XX] In a kinematograph projector for films having a sound track, and comprising means for preventing undue slipping of the film at the place at which the sound record is scanned, means is provided for controlling simultaneously an adjustable brake for the winding-off spool, a device for adjusting the tension produced by the winding-on spool, and an adjustable pressure member at the picture gate, the apparatus being thereby adaptable to films of different kinds ; means for adjusting the focus of the scanning lens, for inserting a filter in the sound projection beam, and for regulating the sound amplifier, may also be coupled to the controlling means. The apparatus may be adapted for films in which the image is carried in a gelatin layer or in which it is a diazo-salt embedded in cellulose hydrate, and, as shown, comprises a control lever 12 on a shaft 13 provided with levers 14, the lever 12 being movable to either of the positions 0, S. The levers 14 engage pressure members 4 at the picture gate, and are connected by cords 15 to braking means 16 at the winding-off spool 2, to a friction disc 17 in the drive to the winding-on spool 10, and to a lever 18 for adjusting the focus of the scanning lens 8. If the transparencies of the different films differ for different parts of the spectrum, a correcting light-filter may also be moved into or from the sound beam by movement of the lever 12, or, if the contrasts in the sound track images differ in the two types of film, the sound amplifier may be adjusted by the movement. The scanning drum 6 may incorporate or be coupled to a flywheel, and rollers 7 may press the film on to it.

Abstract: 959,801. Springs. ROCKWELL-STANDARD CORPORATION. April 19, 1961 [April 20, 1960], No. 14106/61. Heading F2S. [Also in Division B3] A vehicle spring comprises a single leaf spring 86 of a constant width, tapered from the central portion outwards, and with the end portions formed into attachment eyes 68. The desired mechanical properties are obtained by heating a blank to 1200‹ to 2250‹ F., taper rolling to produce the taper, end thicknesses and longitudinal grain flow lines, forming the eyes, reheating to the austenitizing temperature and oil quenching to obtain a 85% to 95% martensitic structure between camber forming dies 72, 74 and tempering after removal from the dies. The spring leaf is restrained in a flattened condition and shot peened on its tension face and finally preset by loading it in excess of its maximum service deflection and the yield point of the material to introduce residual stresses into the leaf to counteract the actual operational stresses.

Cork, cutting. - In making cork shavings, blocks of cork are secured to the rim of a slowly revolving wheel and the shavings are cut from them as they pass over the edge of a quickly revolving circular knife. The shaft 2, on which are secured the work carrier wheel 1 and a belt pulley 2<x>, side by side, is mounted in bearings 3, capable of vertical adjustment by the screw 7. This screw is revolved by the shaft 2 through the bevel wheels 9, the shaft 8 and a gear train 12, 15 so that the blocks are continuously fed on to the knife. The work carrier is also capable of vertical adjustment by the hand wheel 36, the mechanical feed then being out of mesh. The knife 18, vertically adjustable by the hand wheel 26, is revolved by the belt pulley 28 and the edge of this knife is sharpened by two abrasive wheels 42, one bearing on the upper surface, and one on the lower surface of the knife. Vertical adjustment of the abrasive wheels is obtained by the screw 46 moving the frame 44 in the slide bed 45, which is itself secured to the main frame of the machine. The shavings are cut into strips by the knives 30, which, spaced by ferrules on the rod 31, cut the surfaces of the cork blocks 20, just prior to those coming into contact with the revolving knife.

Abstract: 1,161,926. Mosaics. R. DE LA RIVE BOX. 3 April, 1967 [4 April, 1966], No. 5114/67. Heading B6G. [Also in Division E1] A mosaic comprises a plurality of mosaic elements each having a plane surface bounded by faces perpendicular thereto and having coupling members to connect the element to other elements and located at the corners of the element where adjacent faces meet, each coupling member lying wholly inside the periphery of the plane surface, the elements being arranged with their adjacent faces in abutting relationship, and connecting members co-operating with juxtaposed coupling members of adjacent elements of the mosaic to detachably secure the elements together. The coupling means may comprise protrusions directed away from the main plane of the mosaic and the connecting members may be rings gripping around the protrusions. Alternatively the coupling means may consist of holes and the connecting means may comprise elements containing pins which can be stuck in the little holes, recesses being provided in the mosaic element to take up the connecting elements, e.g. the connecting elements may consist of circular discs having pins protruding perpendicularly on them and a recess in the form of a sector of a circle having the same thickness as the discs is mounted on the places where coupling means are desired. The coupling means may be provided at the corners and along the sides of a mosaic element. In Fig. 1 a mosaic element 1 is provided at the corners with protrusions 4 having the shape of a rectangular sector of a truncated cone. Connecting elements are illustrated in Fig. 2 (not shown). In Fig. 5 (not shown) a mosaic is built up out of rectangular mosaic elements using circular and semicircular ringed members as connecting elements. Other forms of mosaic elements can mutually co-operate (Figs. 6 and 7, not shown). The rings may be elastic so that they clamp the protrusions firmly against each other. The inner surface of the rings may not exactly correspond with the outer surface of the protrusions, e.g. cylindrical protrusions can co-operate with rings having at least over part of the their heights a conical inner surface. A locking action between the protrusions and rings may be provided by giving the rings an inner groove and the protrusions a corresponding rib so that the ring can be shifted over the rib under elastic deformation until the rib falls in the groove of the ring. Mosaic elements at the edge of the mosaic may have curved side faces.
