Title: Automated slitting system
IPC: B26D7/26
Filed: 1967-01-04
Abstract: A system for controlling a plurality of slitter units for dividing a supply roll of web material into smaller rolls comprises a computer, responsive to a plurality of inputs corresponding to demanded sizes, which selects a group of inputs providing a minimum of waste when the roll is divided and a plurality of positioning motors for the slitting units responsive to the selected inputs. As shown, a digital computer 11 is supplied with information on punched cards 12 derived from order data sheets 13. The computer reads and sorts the information on the cards and delivers output signals to a display unit and control console 14. The mode of display is determined by selector switches 14a, 14b and switches 14c set information relating to the operating state of the system into the computer for integration with the information from the punched tapes. The computer issues command signals to a slitter control 22, through a line 23, which controls the operation of slitter motors 24. Feedback signals, indicative of slitter position is applied to the slitter control through a line 27. A manual entry control 29 may be used to over-ride any of the command signals from the computer 11 and the distance between a slitter band and the corresponding slitter blade is adjustable in small increments by a manual entry control 31 delivering signals to the slitter control 22. A unit 20 prints a label, or prints directly on the paper, warehouse storage data. In an alternative arrangement, a digital to analogue converter is used to enable a summing circuit to be used for manual or automatic control of the positioning motors. In other arrangements the slitters are positioned by stepping motors or clutches responsive to digital signals.

Title: Method of removing unwanted lines from a master negative transparency
IPC: G03C5/08
Filed: 1967-03-17
Abstract: In photographs of nuclear particle tracks obtained in a bubble chamber (Fig. 3) the unwanted tracks 22 are eliminated, leaving only the tracks and markings 24 which are required Fig. 5 (not shown). Initially the negative 10 is mounted in the projector of Fig. 1 (not shown), light from a source 12 passing through a condenser 14 to throw an image of the negative, by means of a projection lens 16, on to a blank white sheet mounted on a support 20. The image thus produced is that of Fig. 3. The tracks which are required are then emphasized by an operator using a brush and dark ink. The image now appears as in Fig. 4 (not shown). A light-sensitive copy film 26 is now placed in contact with negative 10, and the condenser 14 is replaced by another condenser 30 of longer focal length. A further exposure by light source 12 will now act on film 26 in all places except those corresponding to all the tracks shown on Fig. 3. At the same time, the sheet on support 20 is illuminated by further lamps 28, 28', the image thereon being thrown by reflected light back on to film 26. In this case the image consists only of the emphasized lines, so that if the two images on film 26 are in correct register, the film will be exposed in those places corresponding to the unwanted tracks 22. Thus when film 26 is developed, it will produce a photograph of the required tracks only Fig. 5 (not shown). Figs. 6 and 7 (not shown) give practical details of the copying apparatus. The original negative can be chosen from a negative reel (10) winding across from one spool (40) to another (40'). The light-sensitive copy film (26) can also be wound across from one light-tight cassette to another, and clamped against the negative (10) by vacuum means. Vacuum means can also be used to hold the blank sheet against support 20.

Title: Field responsive photoluminescent display devices
IPC: H01J29/10
Filed: 1973-12-13
Abstract: Improved image storage and display devices of the type which includes a layer of phosphor material which is stimulated to emit light through photoluminescence. The intensity of emitted light is varied by applying an electric field to the phosphor layer. The field may be applied to the phosphor layer by sandwiching the layer between a layer of insulating material and a layer of electrically conductive material and subjecting the insulator to an electron beam. To alter the field strength at selected locations a writing electron beam is focussed on the insulator at these selected locations. In the alternative, the phosphor layer may be covered on one surface with insulation materials forming a charge trap and the phosphor and insulation layers sandwiched between sets of orthognal electrically conductive strips. Selective field alteration is accomplished by X-Y addressing an orthognal pair of conductive strips.
