Title: Improvements in or relating to Apparatus for Separating a Blank from a Supply of Blanks
IPC: B65H3/08
Filed: 1968-12-05
Abstract: 1,183,550. Separating sheets. KOPPERS CO. Inc. 5 Dec., 1968 [15 Dec., 1967], No. 57905/68. Heading B8R. Apparatus for assisting separation of the lowermost blank from a stack includes a telescopic suction device engaging the blank to position its leading edge for passage through an opening. General arrangement.-A stack of blanks 18 is supported on a bed-plate 12, Fig. 5c, and fed, in turn, to feed rollers 22 by reciprocating pushers 56 having upstanding lips 60 which engage the lowermost blank 16; a plurality of back-stops 52 carried on transverse bar 54 raise the trailing edges of the blanks to provide a space beneath the stack for the pushers 56. Gates 20 are vertically adjustable to define an opening 13, Fig. 1, and are also laterally adjustable for different sheet widths, (Fig. 4, not shown). A telescopic pneumatic device 10, below each gate 20, draws the leading edge of blank 16 down towards the opening, and continues to act on the blank during separation. Assisting separation.-Each device 10 comprises an open-ended tubular member 24, Fig. 1, telescopically sliding in a sleeve 26 and connected at its lower end by header 30 to a vacuum source. This tubular member is generally formed of rigid plastics material, and is urged into engagement with blank 16 by spring 34, sleeve 26 being fixed to the bed-plate 12. When suction is applied, it is sufficient to draw the tubular member 24 into the sleeve 26 against the action of spring 34, and the blank is thus aligned with the opening 13 (also Fig. 2, not shown). The suction is sufficiently weak to allow the blank 16 to slide across the open end of tubular member 24 during feed. The tubular member 24 may be locked in an inoperative position (Fig. 6, not shown).

Abstract: 1334367 Extracting sugar FRENCH OIL MILL MACHINERY CO 17 Dec 1970 [18 Dec 1969] 59831/70 Heading C6B [Also in Division B1] A continuous process for the extraction of juice from material such as sugar cane utilises a mechanical screw press with a plurality of sequentially arranged sections and means for collecting liquid separately from a drainage cage for each section and recirculating it back to the material passing through the preceding section. As shown, raw sugar cane C passes through a chopper 12, crusher 15 and shredder 24 to a conveyer 28 by which it is transferred to the inlet hopper 48 of a screw press 50. The bagasse emerging from the press is transferred by conveyer 100 to the hopper 115 of a further screw press 120 which it leaves at 84. The screw press 50 is driven through a gearbox 57 which causes the worm 53 of the inlet section to be rotated at higher speed than the worms of the succeeding sections 60a, 60b, 60c, 60d. Radially adjustable breaker bars 55 are provided at one or more locations where the worm 53 is interrupted, and the worm is surrounded by spaced screen bars 54. The worms of the succeeding sections consist of separate members 60a 1, 60a 2, 60a 3 etc. separated by collars 66 and surrounded by spaced screen bars 72 and breaker bars 68. The worm member at the discharge end of each section, e. g. 60a 3, increases to a larger diameter at its downstream end. Bagasse is discharged through a ring 64. Each section of the press discharges liquid to a sump 88, 88a .... 88d provided with a pump 90, 90a .... 90d. Fresh water fed to a manifold 110 over the upper end of the conveyer 100 passes through the bagasse into a collecting pan 111 whence it joins liquid extracted by the press 120 and passing through a conduit 125 to a manifold 105 at the lower end of the conveyer 100. This liquid is collected in a pan 106 and pumped to an injector 85 in the last section of the press 50 the drainage from which is pumped into the preceding section, and so on back to the section immediately following the feed section where liquid withdrawn by the pump 90a is delivered to a manifold 38 at the upper end of the conveyor 28 to pass through the shredded cane to a pan 44 and thence to a further pan 44 at the lower end of the conveyer where it joins liquid passed through the cane from a lower manifold 38 to be collected in a tank 132 for pumping to  the boiling house. The lower manifold 38 is fed with liquid from the pump 90 draining the feed section of the press 50. Depending upon the setting of valves 135, 137 the cane entering the shredder may be supplied with liquid from the pump 90 or juice from the crusher 15.

Title: Cathode ray display tube
IPC: H01J29/98
Filed: 1978-06-14
Abstract: In display apparatus comprising a cathode ray tube having a channel plate electron multiplier placed adjacent to the luminescent screen to intensify the beam current of said tube, the gain of the channels varies from channel-to-channel across the plate and produces an unacceptable degradation of picture quality. This problem is solved by compensating for the channel gain variations during scanning at the picture element rate. A coupling unit C.U. derives a signal related to the picture element current delivered by the channel plate 8 to the screen 10. This signal is compared with the video input signal to be displayed and a control signal 17 is derived which is used to regulate the beam current so that the picture element light output is substantially directly proportional to said video signal, irrespective of the channel gain variations across the channel plate.   <IMAGE>
Patent GB-2023789-A (GB)
Title: Method and apparatus for cooling or freezing
IPC: A23L3/36
Filed: 1978-06-16
Abstract: A method of cooling or freezing articles, particularly foodstuff items of a type which if refrigerated in mass tend to stick together undesirably. Such as extruded scampi 7, are deposited individually onto the surface of a rotating thermally-conductive drum 2, the interior of which is exposed to a cryogenic medium such as a pool of liquid nitrogen 3. The scampi receive a crust freeze whereby they adhere to the drum as it rotates, until they are brought towards the lowest point of its orbital path. Here they encounter a higher rate of heat loss due to the proximity of the cryogen, and the consequent thermal contraction breaks the bond with the drum, allowing the scampi to drop off whence they are collected by a conveyor 8. Cold vapour derived from the cryogen and which is permitted to escape from the drum is directed over the scampi by fans 10 and 13. <IMAGE>
