Patent GB-1291221-A (GB)
Title: Electron probe forming system
Inventor: SMITH KENNETH CHARLES ARTHUR
IPC: H01J37/073
Filed: 1968-07-07
Abstract: 1291221 Electron guns K C A SMITH and D J SWANN 7 Oct 1969 [7 July 1968 29 April 1969] 27117/68 and 21770/69 Heading H1D An electron gun for a scanning electron microscope comprises a cathode 1 and an anode 5 disposed within a magnetic lens. The cathode is preferably of the field emission type and may include a tip of lanthanum hexaboride about 100  in diameter, and the cathode support may be mounted on a bellows (15, Fig. 1, not shown) so that its position may be adjusted. The lens includes two polepieces 8 and 10 each with a central aperture, and may be adapted to operate with a short focal length and unit magnification. The anode 5 comprises a tube with a small aperture at one end for the beam, and the tube is connected to its own vacuum pump (not shown) so that the pressure within it may be lower by an order of magnitude than that in the rest of the apparatus. A control electrode 18 may be provided, as shown in Fig. 4, and may be pulsed to extend the life of the cathode. A beam limiting diaphragm 19 may be provided in the end-wall of the anode. Electron bombardment of the anode, with consequent release of gas, may be avoided by arranging that the magnetic lens produces a first focus at the anode aperture and a second focus in the plane 17 (Fig. 3, not shown). In another mode of operation, the magnetic lens magnifies strongly, and a second lens (not shown) is provided to demagnify the focus to produce the final probe.

Title: Improvements relating to heat-transfer apparatus of the water-tube boiler type
IPC: F22B21/22
Filed: 1933-08-04
Abstract: 422,220. Water-tube hot-water boilers. LEWIS, W. Y., 16, Woronzow Road, St. John's Wood, London. Aug. 4, 1933, No. 21987. [Class 64 (i)] A boiler consists of rows of contacting circular or looped tubes 7<a>, 7d, secured to the V-shape or parallel sides of a header 3 having a detachable cover 4, the rows of tubes forming walls between which the heating gases are directed in a sinuous path by baffles 9. The gases from a furnace 13 flow upwards over the outer wall of circular tubes 7<b>, pass by way of recesses 15 in the back wall of the heater into the annular space 16 between the tube walls. The gases pass from the two sides of the annular space through a recess 15<a> in the front wall and then flow through the central space 8, containing air heaters 20 and enter the outlet flue 19. The gases may be directed from front to back through the annular flue, on one side of the heater and from back to front in the annular space on the other side. Water flows from a trough 5 over some of the inner tubes through the tubes to a compartment 24 on the other side of the header, and returning through the other inner tubes it enters the outer tubes, which open into the outlet compartment 26. In a modification, the tubes are heated by the hot gases from an oil burner in the central space 8, and the inlet trough is arranged over the ends of some of the outer tubes.

Title: Packaging snack food products
IPC: B65B43/44
Filed: 1975-05-21
Abstract: 1499419 Packaging groups of articles GENERAL MILLS Inc 21 May 1975 [3 June 1974] 21992/75 Heading B8C Apparatus for packaging chip-type food products comprises means for dividing an elongate array of chips into curved segments and means for inserting a series of segments into a container to form a packaged curved array. Chips are supplied under gravity down a track 31 defined by a platform 32 and rails 33, 34, and are gripped by driven belts 36, 37 which feed them to a profiled guideway 43, Fig. 15, and thence, aided by a driven belt 46, on to a gate 103, Fig. 7, located above a container feeding star 191, Fig. 5. Above the gate 103 is located a series of carriages 72, constrained for rotation with a carrousel 52 arranged to be driven by a motor 122 through gears 138, 114, 116, 64. The carriages 72 are vertically movable during rotation by rollers 92 running on a track 110a and springs 1106 surrounding rods 67 b  linking the carriages 72 to the carrousel 52 for rotation urge the rollers 92 into camming engagement. Each carriage 72 has a blade 92 for engaging a leading chip in a respective fed segment, and as rotation of the carriages 72 proceeds during feeding, the blade 92 of the succeeding carriage descends under the control of the track 110a to enter between two succeeding chips to divide the segment from the following one. Movement of the gate 103 to allow the segments to drop into containers fed below the gate 103 by the star wheel 191 is effected by a further series of carriages 71, similarly mounted for rotation with the carrousel 52 and for vertical movement governed by a cam track 110b. As the segment of chips forms above the gate 103, a projection 79 on a respective carriage 71 engages a projection 106 to rotate a hub 101 bearing the gate 103 against the action of a spring 104. When the blade 92 enters between the chips to define the segment, the carriage 71 moves downwardly to disengage the projections 79, 106, whereupon the spring 104 retracts the gate 103, and a pusher 83 pushes the segment downwardly to enter the container, which is filled with a series of segments similarly supplied in turn. Containers are fed from a nested stack in a hopper 163, Figs. 1 and 2, by a de-nester (167), Figs. 17 and 18 (not shown), to be engaged by the star 191 and positioned in turn below the carrousel 52, where they are raised by a camoperated elevator 301 for filling. A chip divider 107 is provided to locate the respective segments in the container until it has been filled completely.

IPC: B65B53/02
Filed: 1961-06-20
Abstract: 986,846. Packaging. GORDON JOHNSON CO. June 20, 1961, No. 22171/61. Heading B8C. An article, e.g. a dressed chicken, is placed within a tray 14, Fig. 9, of thermoplastic heatshrinkable material, e.g. of orientated polystyrene, to which a lid of similar material is applied, and the opposed abutting marginal portions 24, 30, 32 of the tray and lid are heated to soften them, after which the softened portions are brought to a higher temperature and pressed together whereby those portions are melted and fused together. The tray, which is opaque, has reinforcing ribs 22 and indentations 26 extending along the marginal portion or flange 24, and the top 28 of the lid conforms to the shape of the article; the lid is transparent. Apparatus for heat sealing four packages simultaneously includes a housing with openings in its top wall to accommodate heating elements 48, each of which receives two containers and is shaped correspondingly. The cross-sectional shape of the walls of the elements 48, Figs. 5-7, are as shown; they have electrical resistance heating elements embedded in them and are grooved to receive the marginal portions of the container during the sealing operation. Two apertures are provided in each element, and each aperture receives a vertically adjustable container support or platen 130 mounted on a rod 128 slidable in a cylinder 94 secured to a wall 88. A sleeve 104 within the cylinder carries a plate 108 supporting a tray member 110. The lower end of each rod abuts a horizontal rod 142 reciprocated vertically by two double-acting fluid operable piston and cylinder assemblies 172. A vertically reciprocated ram head 156, Figs. 5-7, is associated with each platen and is attached to a cross-bar 154 mounted on rods 150 secured to the rod 142. Fluid supply to the piston and cylinder assemblies, thence the drive of the platens and ram heads, is controlled electrically, and the arrangement is such that initially the platens are raised to the position shown in Fig. 5. Filled containers are placed upon the platens which, together with the ram heads, are driven downwardly and cause the containers to be placed in a pre-heat position, shown in Fig. 6. In this position the container margins are held between flanges of the ram heads and the rims of the tray members 110, and those margins are heat softened. Further downward movement of the rod 142 is then effected, after a predetermined period, to force the ram heads downwardly still further, whereupon the tray members and platens are urged against the action of springs 107 in the cylinders 94 to the position indicated in Fig. 7. The container margins are urged into close engagement with the grooves of the heaters whereby those margins are melted, shrunk and fused together. The platens 130 are then raised for the removal of the sealed package and the reception of unsealed ones.
