Title: Method and apparatus for removing a waste material portion from a partially severed sheet
IPC: B26D7/18
Filed: 1951-06-25
Abstract: 696,398. Cutting sheet material. CORNELL PAPERBOARD PRODUCTS CO. June 25, 1951. [Nov. 3, 1950] No. 15019/51. Class 31 (i). A method of removing waste portions from a sheet which is partially severed along lines defining a plurality of container forming blanks comprises jetting a pneumatic blast solely against the waste portions to dislodge them from the sheet, while retaining the container forming blanks in the sheet. Individual sheets 15, e.g. of cardboard, are successively delivered from a stack 10 on to a matrix die 12 by means of a conveyer 11 and after each sheet has been partially severed by a reciprocating die 13 it is advanced by a conveyer 19 comprising laterallyspaced endless bands into proximity with air blast nozzles 50 which are connected to branch pipes 42 of a main supply pipe 43 through the intermediary of solenoid valves 41 controlled by a switch 33 having an actuator comprising a cam 26 mounted on a rotatable shaft 25 and having adjustably secured thereto members 30 which successively engage a spring 36 to close the switch. Each nozzle is adjustable longitudinally and laterally of the path of the sheets. After the waste portions 17 have been dislodged from the sheet it is delivered on to the top of a stack 150 and to facilitate registration of successive sheets, the marginal waste portions are preferably retained in connection with each sheet. The waste portions are guided by a pan 53 to a collecting hopper. In a modification, Fig. 8 (not shown), the nozzles are operated selectively in any sequence by providing each solenoid valve with an individual control switch and providing each switch with a separate actuator.

Title: Improvements in apparatus for the separation of gases from liquids
IPC: B01D19/00
Filed: 1922-05-29
Abstract: 204,363. Wade, H., (Elliott, W. S.). May 29, 1922. Liquids and gases, separating.-In an apparatus for separating gases from liquids, particularly for use in boiler installations, economizers &c., of the type in which heated liquid is discharged into a chamber maintained at a pressure such that a portion of the liquid evaporates, the vapour being subsequently condensed, the necessity for piping between the separate units is obviated by placing the condenser inside the evaporating chamber. The condenser is preferably open to the vapour space of the chamber throughout a substantial portion of its length to prevent localized flow therethrough, and a valve is provided whereby the liquid is discharged into the chamber at substantially uniform velocity. Liquid is supplied to an inlet 5 of a chamber 6 provided in a removable head 4 of a cylindrical container 2 and flows thence through the tubes of a primary condenser 7 to a header 8 on the movable head 3. It then flows through the tubes of a secondary condenser 9 to a second chamber on the head 4 from which the liquid leaves the apparatus to be heated to the required temperature. It re-enters the apparatus by a valve 12, operated by a float 13, actuated by the liquid level in the container 2, and passes to a secondary spray valve 15, which by means of a stem 17, spring 21, and adjustable follower head 20 is adapted to open under a predetermined static head and to deliver the liquid at substantially constant velocity to the spray pans 23. The chamber 24 is maintained, by means of a steam ejector 27 fitted to the primary condenser 7, at a pressure such that the liquid will boil. The vapour formed and released gases pass to the condenser 7 by an opening 25 extending the whole length thereof. The flow area of the condenser decreases towards the outlet 26, so that the flow of gases is uniform. The condensed vapours, together with the steam from the ejector 27, then pass to the space surrounding the tubes of the secondary condenser 9. The degasified liquid is withdrawn from the chamber 24 by an outlet 29. In a modification, Fig. 6, designed to operate at atmospheric pressure, the ejector and secondary condenser are eliminated and the degasified liquid is passed through the spaces between the tubes of a heat exchanger 31 prior to being withdrawn. The raw liquid is first heated in the tubes of this heat exchanger before passing to the primary condenser 7, and before being sprayed is heated to more than 212‹ F. Specification 155,864 is referred to.

Title: Improvements in the manufacture of kinematograph cartoons
IPC: G03B15/08
Filed: 1944-08-09
Abstract: 595,255. Pictures. TRIGGS, W. W. (Walt Disney Productions). Aug. 9, 1944, No. 15152. Drawings to Specification. [Class 11] [Also in Groups VIII and XX] A hand made picture used in the production of a kinematograph cartoon is drawn on a sheet of transparent material with a matt surface. The effect of the matt surface is then removed by coating with another material of the same refractive index as the sheet. The protective layer may be applied as a lacquer such as ethyl cellulose dissolved in toluene, to which are added resins such as " Santolite " or "Aroclor " (Registered Trade Mark) to correct the refractive index. Alternatively refined mineral oil or a polymerised oil such as " Vistac " may be used, retained in place with another transparent sheet sealed to the main sheet at the edges. To colour the picture paint may be applied to the back of the main sheet and protected with a further sheet. U.S.A. Specification 1,143,542 is referred to.

Abstract: 1363882 Cathode-ray tube displays; photocomposing INTERNATIONAL COMPUTERS Ltd 20 April 1972 [15 May 1971] 15154/71 Headings H4F and H4T Blocks of data to be displayed are derived from a selected one of two picture signal generating devices 3/1, 3/2 (Fig. 1) and during a first scanning cycle are stored in a predetermined area on the storage electrode of a storage tube 1 and during a second scanning cycle are readout and stored in a selectively modified position and/or attitude on the storage electrode of a second storage tube 2 which is then scanned with a television-type raster and the output signals displayed on a monitor tube 10. The display is then recorded by means 11, e.g. a camera or video tape recorder. The picture signal generating devices 3/1, 3/2 may comprise flying- spot scanners, film or video tape scanners or character generator and these are selected as required via gate 4 by manual control means 5 operating via a processor 6 and manipulation control 7 which also control the two scanning cycles. During the first scanning cycle control 7 and address decoder 8 operate to store the selected data blocks at the required positions in storage tube 1. During the second scanning cycle in which the data is transferred to storage tube 2 scanning of both storage tubes is controlled by the arrangement shown in Fig. 2 comprising D/A converters 12, 13 supplied with the outputs from the less and more significant halves of one accumulator 14 fed with input clock pulses and providing the X and Y deflections for tube 1 together with (digital) differential analysers 15, 16 which provide incremental deflections via gates 21 and 22, position register 17, 18 and D/A converters 19, 20 for the deflection of tube 2. In operation, if no change in the position, size of attitude of the stored data in tube 2 is required the gates 21, 22 are controlled at clock pulse rate whilst by changing the rate of opening of the gates together with the production of appropriate shifts in the accumulators forming part of the analysers 16, 16 the scale of the storage "image" in tube 2 may be altered. When the "attitude" of the stored "image" is to be altered, e.g. by rotation, crosscoupled differential analyses 23, 24 connected to analysers 15 and 16 perform the required computation and supply the necessary increments of deflection to the position registers 17, 18. When the data blocks comprise colour images separate scans are produced for each component colour and separate storage tubes I and 2 are provided for each of the latter.
