Title: Charged particle beam apparatus having means to observe a stereo-image of a specimen
Inventor: OKANO HIROSHI
IPC: H01J37/28
Filed: 1970-04-07
Abstract: 1300624 Electron microscopes HITACHI Ltd 7 April 1970 [9 April 1969] 16405/70 Heading H1D In an electron microscope the angle of incidence of the beam on the target may be varied to enable stereoscopic images to be obtained. In Fig. 5 the beam is focused by a lens 3 on a specimen 6 over until it is scanned by a coil 5, and passes through one of two apertures in a diaphragm 10 according to the position of an adjustable shutter 11; the apertures are on either side of the axis so that the angle of incidence of the beam is different for the two apertures, and if desired a third aperture may be disposed on the axis for use when stereo pictures are not required. In a modification, Fig. 6 (not shown), the beam is divided into two by an electrode (12), the two beams passing respectively to two apertures in a diaphragm and one of the beams being deflected away to an inoperative position by a deflection means (13, 14). This arrangement allows high speed scanning and direct display of the two images in different colours on a colour picture tube. In another arrangement, Fig. 7 (not shown) a magnetic deflection means is provided in the image plane preceding the lens 3 and energized to give two alternate paths for the beam through the lens. In a modification, Fig. 8 (not shown), the deflection means is preceded by a diaphragm and is located after the image plane; in this case the scanning coil 5 must be supplied with a waveform inverse to that supplied to the deflection means to compensate for the displacement of the beam. This waveform may be synchronized with the scanning wave (Fig. 9, not shown) but this is not essential.

Abstract: 1487113 Packaging ETUDE ET REALISATION DE CHAINES AUTOMATIQUESERCA 22 April 1975 [25 April 1974] 16590/75 Heading B8C A container 6 is sealed by a profiled lid 12 and a cover sheet 42, the lid comprising an inner dished portion seated freely on the rim of the container and connected by at least one tongue to an outer ring portion sealed to the container rim, the cover sheet being sealed only to the outer ring portion. A container band 5 is heated at 1, thermoformed at 2 and filled at 3. A lid band 10 is similarly heated and thermoformed and then the inner portion is partially cut away from the outer portion leaving either a continuous or discontinuous join along the leading edge or a tongue in the middle of each side. The lid band carries the lids around a semicylindrical guide plate 30 and positions them over the containers. After the cover sheet band is placed over the lid band the three bands are welded at 44 and the closed containers cut out of the bands at 45. Each lid is formed with a central gripping button for opening the lid after the cover sheet which may be of an aluminium-thermoplastic film has been unpeeled. The tongue(s) at the leading side may form a hinge and those at the sides may be weakened to arrest breaking.

Title: Improvements in or relating to safety devices for lifts, skips, cages and the like
IPC: B66B5/20
Filed: 1942-11-24
Abstract: 563,591. Catch gear for lifts. MACLEAN, G. R., and BARDER, H. Nov. 24, 1942, No. 16651. Convention date, Dec. 23, 1941. [Class 78 (iii)] A safety device for lifts, mine cages, and the like, comprises a cross-bar that extends between and slides on opposite guides in a lift shaft, and brake shoes pivoted to the cross-bar and to a lever pivoted in the lift cage, the arrangement being such that the shoes are held out of contact with the guides when the haulage cable is intact but are forced against the guides if the cable should break. The brake blocks are covered with a layer of soft, readily fusible metal. The cross-head 6, Fig. 1, is provided at its end with runners 7 that engage the shaft guides 3. The brake shoes 12 are pivoted at 10 to the runners 7 and also to links 16 which are pivoted to the sides of the cage 1. Springs 14 urge the brake shoes into contact with the guides 3, but a loop 5 of the haulage cable 2 passes through holes 20 in the ends of the links 16 and normally holds the brake shoes in the position shown. If the cable 2 should break, the shoes are swung downwards into contact with the guides by the springs 14 and by gravity, and when the fall of of the cage'is arrested, its weight keeps it in the arrested position. A canopy 23 with inclined sides is fitted to the cross-bar 6 to protect the cage from damage by a falling cable. Each brake shoe 12 is fitted with a pair of inclined brake blocks 25, Fig. 4, a curved leaf spring 25a arranged between them, and a body 26 of readily-fusible metal moulded over the blocks. When the brakes come into action, the friction between the guides 3 and the bodies 26 heats and melts the fusible metal, and the braking-friction is brought into action gradually.

Title: Improvements in or relating to the production of films of thermoplastic materials
Inventor: SAMWAYS BRUCE
IPC: B29C48/10
Filed: 1952-07-07
Abstract: <PICT:0744977/IV(a)/1> <PICT:0744977/IV(a)/2> Apparatus for making films of thermoplastic material in the form of rolls comprises an annular extrusion die for extrusion of the thermoplastic material in the form of a seamless tube, means for cooling and processing the tube, means for flattening the cooled and processed tube, means for winding the tube in flattened form as a roll, the winding and flattening means rotating in one unit, and means adapted to cause continuous or reciprocatory rotation of the flattening and winding means relative to the die, or of the die relative to the flattening and winding means, about an axis perpendicular to the plane containing the orifice of the die and coinciding with that passing through the centre of the die.  As shown in side elevation in Fig. 1, molten polyvinyl chloride is extruded vertically upwards from the fixed die 11 at a speed of 0.5 feet per second to form a seamless tubular film 12.  This tube, after cooling, is flattened by passage through the pair of driven nip-rollers 13, 14 to form a double sheet 15 having creased edges which are trimmed off by two knives, one of which is shown at 17.  The two sheets 18, 19 thus formed, after passing between nip-rollers 20, 21, are wound on the two driven mandrels 22, 23 to form rolls 24, 25.  The creased edges 26, 27, which were trimmed off by knives 17, are discarded to waste.  The nip-rollers 13, 14, 20, 21, the knives 17 and the mandrels 22, 23 are mounted on the turntable 28 which is rotated (by means not shown) continuously at a steady rate of 0.005 revolution per minute about an axis perpendicular to the plane containing the orifice of the die and passing through the centre of the die.  In the modification shown in plan view in Fig. 4, the upwardly extruded seamless tube of thermoplastic material, after passage over the cooling and stretching mandrel 32, is cut by knives 33, 34, 35 mounted in a frame (not shown), and the three strips thus formed are led over rollers 36, 37, 38 to individual wind-ups 39, 40, 41.  All the rollers and knives and the wind-up mechanism are so mounted that they may together be caused to rotate simultaneously about an axis perpendicular to the plane of the die and passing through the centre of the die, as in Fig. 1.  The material of the films may be polythene, polyvinyl chloride, polystyrene, copolymers of vinyl chloride with ethylenic compounds, cellulose acetate, cellulose acetobutyrate, superpolyamides such as methoxymethyl nylon, polyesters such as polyglycol terephthalate, or polyurethanes. The preferred rate of rotation or reciprocation in radians per second is 0.01 to 0.00001 of the speed of forward travel, in feet per second, of the extruded tube, divided by the diameter of the latter in feet.  The invention reduces variations in the total thickness of rolls of the film across the width of the rolls.

In the manufacture of water gas, the vaporous hydrocarbons generated in the distillation or preheating zone during the blasting period owing to the heat left therein from the previous steaming period, are condensed by conducting them through and over a stock of cold fuel, the latter and condensed material being then subjected to the usual gasefication. The carbonization zone A is blasted with air at D and the gas passed through offtake F to regenerators. During the " blow " period, off - take K is closed and offtake G sufficiently opened to allow the gas produced in the distillation retort B by the heat generated during the previous "run" to escape to the holder, tar being condensed on the coal. Steam is admitted at H and the water gas generated in zone A mixes with distillation gas in zone B and escapes through offtake K to regenerators. The offtake K may extend into the middle part of the distillation chamber and also serve for introducing carburetting agents.
