[Also in Division A2] Apparatus for cutting paper webs such as cigarette tipping material comprises a rotatable cutter head 1 adjacent a conveyer drum 6, Fig. 2. The cutter head 1, which may carry four cutters 2, is mounted on a rotatable shaft 7, Fig. 1, for limited universal movement about a point on the shaft so that the head can align itself with the conveyer surface at each cutting operation. As described, a ring 8 is attached to a generally spherical part of the shaft by a cross-pin 9, and to the body of the head by stub pins 10, Fig. 3. The holes in the body are larger than the pin 9 to permit relative movement. The shaft is rotated by an anti-backlash gear 11, 11A journalled on a shaft 14, connected to the shaft 7 by a flexible spring coupling 15 and dog coupling arrangement 30. The bores in the cradle ends are eccentric to the bores housing the ball-races 18 for the shaft 7, and thus the cutting knives may be adjusted closer or further from the drum surface by turning a bush 22 by means of a tommy bar 29. This turns a support stub 19, which in turn rotates a cradle 17 mounted on the support stub. A graduated sector plate 27 and datum mark on the flange of the bush 22 facilitate adjustment. To detach the cradle and cutter head the tommy bar 29 is pulled out, turned at right angles to the stub and pulled against the pressure of a spring 28. A web is fed to the cutter by rollers 5 which rotate more slowly than the drum, and is held on the drum by suction through holes in the periphery of the drum.

Title: Improvements in or relating to methods of and apparatus for forming sheet glass
IPC: C03B13/04
Filed: 1926-05-31
Abstract: 263,394. Jackson, L. Mellersh-, (Hartford-Empire Co.). May 31, 1926. Rolling. - Relates to the method of forming plate glass continuously in which a stream of molten glass flowing from a spout passes between rollers which flatten it into a continuous ribbon or band. According to the invention, the glass, instead of flowing from the spout as a single stream, is divided up into two or more streams which are directed on to the sheet-forming rolls. The glass is thus distributed across the face of the rolls and the formation of " ream " in the finished sheet is reduced. The apparatus comprises a spout 11, Fig. 4, from which a stream of glass flows on to a large roller 20 and is carried beneath a smaller roll 21 by which it is formed into a continuous band X. In order to distribute the metal evenly in front of the roller 21, the spout is divided into two or more sections 11<a>, Fig. 1, by means of a wall 11<b>. Instead of using the wall 11<b>, the spout may be made deeper at its sides than at the middle, as shown in Fig. 3, thus causing the greater mass of glass to flow towards the ends of the rollers. The spout may be heated on its underside by a burner 23, Fig. 4, and the surface of the glass may be heated by a gas-heated radiator 30.

Abstract: 1,037,514. Centralized control apparatus. AUTOMATIC TELEPHONE & ELECTRIC CO. Ltd. May 3, 1963 [April 10, 1962], No. 13806/62. Heading G4F. Data handling apparatus includes a number of operators positions each provided with a cathode-ray tube having its face divided into areas appropriate to the display of information; means for inserting data relative to the information into a store; scanning means for extracting the information; and means for displaying the extracted information on the appropriate cathode-ray tube. As described, in an air traffic control system, data, such as speed, relevant to a particular aircraft is displayed on one of a number of cathode-ray tubes, Fig. 1 (not shown). If a change in speed, say, is to be recorded a " joystick " control is actuated to position a ring marker on the tube over the letters SP and operation of an " inject " button causes these letters to appear in the box marked "category code " on the CRT face. The joystick is then moved so that the ring marker rings each of the figures of the new speed in turn pressing the "inject" " button after each movement. This assembles the speed data in the "current amendment " block The marker is then moved to the square "-" and operation of the "inject " button causes the display in the SP block to be amended to indicate the new speed. The new data will then be transferred to the stores of a computer. The local store LS, Fig. 2 (not shown), individual to each operator's position is addressed in a repeated scanning cycle which extracts the information necessary to address the main store CL1. Each row of the local store LS is read out in turn to an output register OR1, which presents the sets of data readout in turn to the main store CL1 via a gate circuit. The main store is then readout in turn into register OR2 and the sets of data presented in turn to a digital-analogue converter DAC via a further gate, to be translated into analogue form for applying to the relevant CRT. When amending an item, the data is first assembled in a temporary store TS, Fig. 3 (not shown), and is then written into the local store LS via write circuit WS during the scanning cycle. Operation of the inject button 1B after marking the square "-" produces a code which is accepted by the gate GATE"-" allows the " category code " to be read out from the temporary store via gate GC, and applied to a translating circuit TC which converts the category code, which is in the form of an address in the main store, to one in the local store corresponding to the block in the CRT to which it refers. At this point the write circuit writes into the selected address the amended data. Errors in the current amendment data may be erased by moving the marker to square " ? " and operating the " inject " button 1B to produce a code which is accepted by gate GATE "?".
