Contaminant gases or vapours may also be gettered by the released material. Body 30 may be sintered (e.g. W), supporting rod 31 may be W or Mo and further cavity 35 includes electron emissive material 34. Element 36 may control dispensing of material 33 during heating or ion or electron bombardment. Choice of material may control dispensation e.g. barium iodide of high b.p. and dissociation temperature is unaffected by lamp manufacture temperatures and requires intentional heating. A single pellet may be a composite of generating and emissive materials, or pellets of both types may be in the same or different cavities. In a method of introduction of the metal or halide, the closed body with source in the cavity, is fitted into the lamp during manufacture. After processing, e.g. introduction of rare gas plus Hg, and sealing, the tube may be operated either separately or in its outer envelope, as a seasoning stage. At this stage, or by induction heating or passage of current for example, the materials may be evaporated. The dispensing component may not be an electrode and may for example be heated by passage of current from either or both electrodes to the component. Reference is made to lamps with Hg and Na (respective partial pressures of 2 and 0À5 atmos.) and Hg with halides of Al, Dy, Ga, In, Se, Na, Tl, Th or Sn, and electron emissive materials of oxides or aluminates of alkaline earths.

Title: Polyethylene films and method of making the same
IPC: B29C48/10
Filed: 1956-01-23
Abstract: Thin, self-sustaining, unsupported, flexible films are produced by melt-extruding polyethylene through an annular orifice to form a tube whose diameter is then increased by introducing a gaseous medium into the tube at superatmospheric pressure and blowing the tube while in the plastic formative stage in accordance with the formula: orifice opening= K (blow ratio)2 wherein the orifice opening is the difference between the radii of the inner and outer lips of the die and is at least 0.007 inch, K has a value in inches, not greater than 0.0018, preferably not greater than 0.0012, e.g. 0.0005 to 0.0010, and the blow ratio is defined as flat width of flattened tubing divided by the outer diameter of the orifice and is 3.5-8.0.  The polyethylene may have a melt index value of 8.5 or less, a value of 0.5-2.5 being preferred (A.S.T.M. Method D1238-52T).  The density of the polyethylene (at 25 DEG C. and corrected for air buoyancy) is preferably below 0.9165, e.g. 0.9130 to 0.9150 when subsequently shrinking the film at 99-100 DEG C., and below 0.9230 when subjecting the film to shrinkage by heating it to above 100 DEG C., e.g. 105 DEG to 108 DEG C.  The temperature of the die may be 270 DEG  to 500 DEG F. and particularly 270 DEG  to 390 DEG  F.  The film produced according to the invention may be used as a protective packaging material, the item to be packaged being inserted in a covering consisting of the film and the package being suddenly subjected to heat to cause the film to shrink, as by suddenly immersing the package in a liquid such as boiling water, propylene glycol, glycerine or aqueous glycerine at 100 DEG C.  Alternatively, saturated aqueous sodium chloride or sodium acetate solution, or aqueous corn syrup, aqueous propylene glycol, aqueous glycerine or tetraethylene glycol may be used at temperatures of 102-108 DEG film.  The film produced may have an extensibility of at least 100 per cent in either the transverse or longitudinal direction without necking down and an elastic recovery of at least 55 per cent.  U.S.A.

Filed: 1976-01-20
Abstract: 1525332 Colouring cementitious articles in a mould P RITTER 20 Jan 1976 02233/76 Heading B5A A cementitious article is provided with a glazed and coloured surface by supplying the cementitious material to a mould having at least part of its surface formed from expanded polystyrene which has been surface patterned or textured and provided with an area or areas of a composition coloured differently to the material. After the cementitious material (concrete or plaster) has set, the expanded polystyrene is partially removed from the article by a solvent, leaving the coloured composition mixed with a solution of the polystyrene on the article to form a patterned, coloured and glazed surface after evaporation of the solvent. Flower pots, vases, lamp bases, sculptings, buildings, bridges, tunnels and panels are moulded. As described for moulding a concrete panel, a mould is used comprising a base and side walls of expanded polystyrene, or a tray having a removable, insert base sheet of expanded polystyrene. The moulding surface of the polystyrene is textured by spraying a small quantity of an organic solvent (toluol or petrol) through a mask, or by applying an electrically heated printing tool, which impresses a pattern or is drawn over the polystyrene to burn out grooves. A mixture of dye and a polystyrene adhesive are applied to the patterned surface, or paint and solvent are sprayed so that the solvent evaporates before touching the surface. The mould is assembled and the concrete cast and left to set, whereafter the expanded polystyrene is removed from the concrete article by (a) dipping the article and polystyrene into a solvent, leaving a small quantity of polystyrene solution and colouring matter on the article, for forming a dull, coloured glaze after the solvent has evaporated; or (b) solvent is sprayed or brushed on to the polystyrene to provide a high glaze from a mixture of the solvent, polystyrene and colouring; or (c) the polystyrene is saturated with an inflammable solvent that is ignited to melt away part of the polystyrene. The concrete panel can be removed from the mould and placed in its in-use position before removing the polystyrene, which acts as a protective packing.

Abstract: 469,431. Toothed gear; printing - machines. HOE & CO., Ltd., R. (Hoe & Co., Inc., R.) Jan. 25, 1936, No. 2426. [Class 80 (i)] [Also in Group XVI] Gears mounted on axes, the distance apart of which is adjustable, are tapered in opposite directions and are mounted for relative axial movement to enable them to be adjusted as to mesh to compensate for changes in the distance apart of the axes. The invention is more particularly applicable to the cutting and folding cylinders of printing machines. In the form shown, the cylinder 16, Fig. 1, is mounted in fixed bearings 22, 23, and drives through the tapered gears 26, 34 the cylinder 15, which is mounted in bearings 29, 31 slidable by pin and slot devices 32 on the fixed frame 17. The gear 34 is slidably keyed to the shaft 27 of the roller 15 and can be traversed by a fork 36 on a rod 41 having a screwed end 49, Fig. 4, engaging an axially-fixed nut 52 having external worm threads engaging a worm wheel 57 on an indicating drum 61. When the nut is turned, the rod 41 moves axially, the squared end 40 of the rod slides in a hole in the frame, and an inclined projecting rib 47 thereon engages an inclined slot in the movable bearing 29 of the cylinder 15, thus varying the gap between the cylinders. The slot is nearly parallel to the taper of the teeth of the gear 34, which thus remains correctly in mesh with gear 26. A movement equal to that recorded by the drum 61 is given to the bearing 31 by a screw 63 rotating past a fixed pointer 70. After the adjustment, the bearings 29, 31 are clamped by nuts 33a. The gears 34, 26 have involute teeth, the hob used in generating them being moved towards or away from the gear axis as it moves axially. The gears may be helical.
