Class 98(1) A deep therapy X-ray apparatus comprises an X-ray tube which, when in use, is supported for continuous movement in combined linear and circular paths, and is pivotally mounted on the support whereby the X-ray beam may be continuously directed to a given area on the axis of revolution during these movements, the support for the X-ray tube comprising an arm which is eccentrically supported by a vertically disposed rotatable disc and is linearly movable parallel to the axis of the rotatable disc, the parallel movement of the arm and X-ray tube and the pivotal movement of the X-ray tube being effected by connecting rods to which are imparted differential movements. As shown, a rod 8 is mounted in a rotatable disc 12 for movement parallel to the axis of the disc, as described in the parent Specification. The rod 8 is moved by a rotatable screw-threaded rod 2, and the X-ray tube 3 is rocked in pivots on rod 8 by a rotatable screw-threaded rod 1 connected to a lever 5 which is linked to the X-ray tube. Rods 1 and 2 are driven by a motor 4, and move together but at different speeds, due either to different gearing to the motor or to different screw threads. 'The ratio of the speeds is such that the beamlimiting diaphragm 7 is always directed towards the same point on the axis of disc 12.

Title: Improvements in apparatus for controlling a material feeding mechanism
IPC: B21D43/09
Filed: 1938-07-19
Abstract: 516,251. Metal-sheet feeds. BURGESS, A. F. (Littell Machine Co., F. J.). July 19, 1938, No. 21395. [Class 83 (iv)] Apparatus for controlling a material feeding mechanism such as may be used with punch presses, includes a rotatable member driven by the mechanism from a starting position, which is manually variable, to a stop position, upon nearing which electrical means operates to slow down the feed mechanism and upon reaching which a second electrical means steps the feed. A portable box 10 is secured to the press with a gear 20 meshing with the feed rolls or a measuring roll. A pointer 54 is set by a hand wheel to indicate the required feed. The mechanism is started by a press button 120 or a switch LS is closed by the press and electric circuits are completed to start the feed roller motor, slow and stop the motor when the feed has been effected and to disconnect the gear train and zeroize the mechanism. The gear 20 rotates a gear 28 connected by a clutch 31 to a shaft 26 carrying a pinion 37 meshing with a gear 38 that carries a cam 90 actuating in succession switches 78, 80, 84. When the switch 84 is closed a solenoid 91 is energized by the closure of a switch C<1> and this through a lever 97 works a shaft 98 to free the clutch 31 to allow the restoration of the mechanism. The drive motor DM of the feed rolls has low and high speed windings LSW and HSW. When the starting switch LS is closed, relay A closes contacts A<1>, A<2>. The contacts A' complete circuit through the feed roll motor DM whilst the contacts A<2> complete a holding circuit for the relay A through normally closed contacts 80. The motor DM runs at high speed until a lug 90 on the member 38 contacts roller 87a to close contacts 78 energizing relay B and causing contacts B<1> to close and B<2> to open. The HSW is cut out and the LSW put in circuit. Continued rotation of the member 38 at low speed causes the lug 90 to engage roller 87 to open contacts 80 to de-energize the relay A opening contacts A<1> to stop the motor and closing contacts 84 energizing relay C to close contacts C<1>, C<2> rendering solenoid 91 operative to start-a return motor for returning the member 38 to a zero position and through the plunger opening the clutch 31.
Patent GB-859306-A (GB)
Title: Improvements in or relating to logic circuits
IPC: G05B19/04
Filed: 1958-07-04
Abstract: 859,306. Photo-electric logic circuits. WESTINGHOUSE ELECTRIC CORPORATION. July 4, 1958 [July 9, 1957 (3)], No. 21463/58. Class 40(3). A logic circuit comprises a first photo-conductor 216 responsive to light from a luminous source 220 electrically controlled by a plurality of further photo - conductors 231, 232 responsive to respective input light signals so that an electrical output signal is produced by the photo-conductor 216 only in response to desired combinations of input light signals. As shown, the photo-conductor 216 is connected in series with a load 226 and an A.C. or D.C. voltage applied between terminals 212 and 213. The luminous source 220 comprises a neon lamp and the further photo-conductors are connected in series with the lamp 220 and a D.C. voltage applied between terminals 210 and 211 so that the arrangement constitutes a logical AND circuit, a voltage output across the load 226 being produced only when both the further photo-conductors are energized by the input light signals. In a modification, Fig. 4 (not shown), the photo-conductors are connected in parallel between the terminal 210 and the lamp 220 to provide an OR circuit and in a further modification, Fig. 5 (not shown), constituting a NOR circuit the photo-conductors 231, 232 are connected in parallel across the lamp 220 so that a voltage output across the load 226 is obtained only if neither of the photo-conductors 231, 232 are energized by the input light signals. Since the neon lamp radiation includes red and green light and most photo-conductors are primarily sensitive to green light, a visual indication of the state of the neon lamp may be provided by a red filter. Combinations of the above circuits may be provided to give desired logical combinations, e.g. AND-OR. The neon lamp may be replaced by an electroluminescent cell separated from the photoconductor 216 by a transparent insulator or lens, the component elements being encapsulated in a container impervious to ambient light.
