Patent GB-640163-A (GB)
Abstract: 640,163. Ticket-issuing machines. BELL PUNCH CO., Ltd., and WEBB, C. F. April 18, 1947, No. 10343. [Class 106 (iii)] [Also in Groups XV and XVI] A totalisator system includes means whereby, in order to make the fraudulent alteration of tickets difficult, the portion or portions of the ticket on which essential particulars are printed is or are scored, ribbed, embossed or otherwise mutilated. A continuously driven roller 1 co-operates with a free roller 2 which turns only when a ticket 4 passes between the rollers and so transmits the drive from the roller 1. The two rollers are formed with complementary grooves which cause scoring, ribbing or embossing over certain printed portions of the ticket as it passes through. To ensure accurate positioning of these areas on the ticket, the roller 2 is arrested after each operation by a roller 5 spring-urged into a notch 6. In addition to a spring 13 tending to urge the roller 5 counter-clockwise about a pivot 8, a second spring 9 engages sections 11 of the printing drum 10 to reinforce this action. The roller 2 is mounted eccentrically for adjustment purposes. Specification 325,873, [Class 100 (iv], is referred to.

Abstract: 776,476. Grinding machines. MESSERSCHMIDT, S. Jan. 19, 1955 [Feb. 16, 1954], No. 1679/55. Class 60 [Also in Group XXII] A grinding machine in which a diaphragm chuck 3 (see Group XXII) and a grinding wheel (not shown) are movable relatively to one another has an arrangement for the automatic feed and removal of the workpieces. The chuck 3 is mounted on a spindle. 2 driven by a pulley 4 and is operated by a ram. 7 carried by a hollow, shaft 6 which is actuated by a lever 10 and a fixed cam surface 14 each time the spindle housing 1 is displaced against the action of a spring 17 by a cam mechanism (not shown). An ejector 8 carried by a rod 5 actuated by a strap 29 connected to a cam-operated driver 27 pushes the finished work-piece 41 into an aperture in a disc 19 which is then rotated to bring the work-piece opposite an ejector 21 and to carry a fresh work-piece from an annular magazine not shown to a position opposite a feed rest 22 which is operated simultaneously with the ejector 21 and feeds the fresh work-piece to the chuck. The ejector 21 and the feed rest 22 are secured to a rod 20 which is operated by the driver 27 and carries cam 35<SP>1</SP> to displace a lever 35 and release a spring- loaded turn key 31 to couple a bevel wheel 26 to the spindle 2. This bevel wheel drives the disc 19 through gearing 23, 24 until the turn key 31 again engages a projection 34 on the lever 35.

Title: Disposal of harmful waste materials
IPC: G21F9/00
Filed: 1978-09-15
Abstract: A process for the disposal of harmful waste materials, such as radioactive materials, consists of drilling a hole 6 in a tectonic oceanic plateau 1 which is in the process of moving under an adjacent tectonic continental plateau 2 and placing the material in the hole 6. Due to the movement of the oceanic plateau 1, the material becomes in time completely covered by the continental plateau 2 and gradually moves deeper into the earth's crust. The hole 6 is preferably sunk from a drill ship 5 in the oceanic plateau 1 near the edge 3 of the continental plateau 2. <IMAGE>
Patent GB-783982-A (GB)
Abstract: 783,982. Weighing apparatus. STEVEDORES EQUIPMENT SERVICES CO., Ltd. Jan. 11, 1956 [Jan. 25, 1955], No. 2151/55. Class 143 In a weighing machine an indicating pointer 32b moves radially in relation to a circular chart 30 which makes more than one revolution for the full weighing capacity of the machine, and which is provided with graduations 30a which lie on either an involute or a spiral path. The chart is carried by a stationary spindle 27 which is rotatable by a rack 25 carried by a cross-bar 24 suspended by flexible ribbons 21 from differential drums 17. These drums are provided with further ribbons 19 anchored at 20 to a stationary frame 13 and are journalled at 18 in a movable frame 11. The indicator 32b and masking plate 33 are secured by brackets 31 to frame 11 which is supported by weighing springs 12, and which is connected to the load by a rod 10. Thus downward movement of frame 11 lowers the pointer 32b and also produces amplified rotation of the chart 30 through differential drums 17. This downward movement of the pointer is such that it intersects the path of the graduations in all positions of the chart. The upper ends of springs 12 are supported by frame 13 through a zeroizing screw 16. In a modification (not shown) the indicator is applied to a pendulum scale. In further modifications described in the Provisional Specification only the chart moves both linearily and rotatively relative to a fixed pointer, or the graduations are inscribed in a series of concentric circles, the relative movement between the chart and pointer occurring at the end of each complete revolution of the chart.
