Abstract: 1,151,247. Utilizing energy of radiation. INTERNATIONAL BUSINESS MACHINES CORP. 15 Nov., 1966 [19 Nov., 1965], No. 51034/66. Heading G6P. In a radioisotope powered battery, the radioactive material is incorporated in a metallic conductor by sputtering the conductor in an atmosphere of the radio-active material. Beta particles are emitted and received at a collector electrode. The emitter and collector are separated by a dielectric which has a low absorption for beta particles but a high resistivity for the low energy back-scattered electrons from the collector. Krypton-85 is employed as the radio-active material, incorporated in an aluminium film and the electrodes are cylindrically coiled. The battery is encapsulated in synthetic resin or lead to absorb beta particles and gamma rays.

Title: Optical deflection apparatus
IPC: G02F1/29
Filed: 1965-12-02
Abstract: 1,060,954. Deflecting light. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 2, 1965 [March 8, 1965], No. 51138/65. Heading H4F. An optical deflection apparatus comprises an electrooptic deflector operable to deflect a beam of light by refraction in response to a sinusoidal voltage applied to the deflector, and a mirror arranged to reflect the light back through the deflector for further deflection after an interval in which time the field produced in the deflector by the sinusoidal voltage is reversed so that the further deflection is to the side of the original light path opposite to that of the initial deflection so that the resultant deflection from the original light path is increased. In the embodiment described, Fig. 1, two electro-optic deflectors 6 and 8 angularly displaced by 90 degrees with respect to each other are symmetrically disposed on either side of the geometric centre C of the optical cavity formed by a pair of spherical mirrors 2 and 4, the light beam entering through an opening 1 in mirror 2. In the absence of any other potentials the presence of a sinusoidal voltage on deflector 6 results in successive deflections of light from axis 3 (along which light enters), Fig. 2, not shown, the cumulative effect of the deflections causing light to escape beyond the edge of one of the mirrors 2 or 4. By arranging that the voltage applied to deflector 8 differs in phase by 90 degrees with respect to that applied to deflector 6 and because the two deflectors are angularly displaced by 90 degrees with respect to each other, the combined effect of the deflections results in light being deflected to trace circles of progressively increasing radius until it goes beyond the rim of either mirror 2 or 4. By changing the amplitudes and phases of the sinusoidal voltages applied to the deflectors an elliptical scan of light may be obtained. Each deflector is formed, Fig. 5 (not shown), by taking two cubes of linear electro-optic material bounded by (001), (110) and (-110) planes with electrodes on the (001) faces, sawing one cube along a diagonal in the (110 plane and the other along a diagonal in the (-110) plane, and cementing one piece from each cube together along their sawed faces. Thus, light will see a refractive index change at the diagonal boundary when a field is applied and be deflected. The linear electro-optic material may comprise zinc sulphide or cuprous chloride.

[Also in Division G1] Discard from a bag-making machine of bags with improperly formed block-bottoms is controlled by means checking the inclined edges 192, 199 (Fig. 6) of the bag bottoms. The edges may be checked by mechanical feelers, by photo-cells, which may co-operate with reflectors which slide under the portions 192b at the flaps, or by beta waves from a cobalt source. In the machine described, the bags move transversely, as indicated by the arrow 189, and photo-cell checking devices 185, 186, 194, 195 are arranged for occlusion or exposure at moments correlated with the exposure or occlusion of corresponding photo-cells 187, 198, 193, 200 detecting the leading and trailing sides of the bags. Operation of the photo-cells associated with the leading inclined edge 192 by passage of the trailing edge 199 is prevented by cam-operated switches synchronized with the bag conveyer. Further detectors (162), (163), (Fig. 1, not shown) detecting opposite ends of the bag sides detect a bag incorrectly oriented in its passage through the machine. When improper folding results in the difference in thickness between opposite halves 229 231 (Fig. 9) of a bottom being greater than normal, this may be detected by rollers 223, 224 which tilt about a central shaft to cause an arm 236 to release a switch 238. To facilitate adjustment of the checking devices for different sizes and shapes of bag, they may be mounted in sets on carriers which are moved conjointly laterally of the conveying path by oppositely handed lead screws. The detectors such as 187 (Fig. 6) detecting the bag sides may be movable in the direction of conveyance, and scales may be provided for all the adjustments to indicate the corresponding bag dimensions.
