IPC: B65H75/10
Filed: 1965-03-24
Abstract: 1,107,593. Bobbins. MINNESOTA MINING & MANUFACTURING CO. 24 March, 1965, No. 12556/65. Heading B8M. A core for a roll of adhesive tape or other sheet material comprises inner and outer concentric annuli in slidable contact with each other, whereby the outer annulus can rotate on the inner annulus when tape is withdrawn from the roll, the inner annulus being formed with a gap, Fig. 2 (not shown). Sheet material may be adhered to the inner or outer surface of the inner annulus so as to cover the gap. A core of this construction may be mounted on a conventional dispenser so that the annuli function as a unit or the sides of the gap may be pushed toward each other so that the outer annulus can rotate on the inner annulus. The cores may be sliced to appropriate width from a tube formed from a plurality of helically wound adhesively bonded plies of chipboard. jute paper or the like, the interface between two of said plies being free from adhesive. A ply lying radially inward of said interface is helically wound with a gap between adjacent lateral edges, Fig. 3 (not shown). One or both of the plies which contact to form the interface may be formed from sheet material having a comparatively smooth surface e.g. calendered parchment or plastic coated paper.

Title: Improvements in kinematographic apparatus
IPC: G03B41/06
Filed: 1919-05-21
Abstract: 153,033. Buss, E. May 21, 1919. Kinematograph apparatus.-In continuousfeed apparatus of the rocking-mirror type, lateral movement of the projected ray is largely prevented by giving the mirror an additional movement perpendicular to its plane. The shutter may be eliminated by employing two or more mirrors so mounted that one begins to operate as the other approaches the end of its operation. As shown in Figs. 5 and 6, two mirrors f are rocked about an axis o by cams q, q<1>, 180 degrees cut of phase, so that their angular movement equals half the angular movement of the ray, and, in addition, they move perpendicularly to their plane. A crank disk wand connecting-rod x reciprocate the shaft o and the mirrors f, the cam-rollers p of which are flanged to engage the cams q, q' and slide along their shafts p<11>. As the film E travels upwards, a picture unit is projected by the mirror f in a stationary direction through the prism g to the screen, the other mirror gradually coming into action and projecting the next picture unit. At the end of its downward motion, the first mirror makes a quick ascent and is then ready to transmit its next picture unit as it comes back into the beam. Any part of the adjacent picture reflected by the mirror is cut out by the diaphragm F so that only the correct unit for each mirror is projected. Fig. 9 shows a modification in which the mirror J, J' are mounted on a wheel of which th does not lie in the plane of the vertical beam, the component in the plane serving to move the mirrors across the beam and the component at right-angles to give the angular motion compounded with the movement perpendicular to the face of the mirror. The mirrors themselves must be perpendicular to the vertical middle plane when they are operating and to secure this they are mounted on radial shafts H and' rocked by levers, the rollers L of which run on the cam N. The correct speed for the wheel is determined by experiment.

Title: Polymerisation of vinyl organic esters
IPC: C08F18/04
Filed: 1941-10-08
Abstract: Vinyl organic esters alone or together with a minor proportion of one or more other specified polymerizable compounds are polymerized in aqueous media in the presence of a water-soluble persulphate and a water-soluble salt of an oxyacid of sulphur with reducing properties. Specified other polymerizable compounds are other polymerizable compounds containing the group <FORM:0574449/IV/1> , e.g. vinyl chloride, unsymmetrical dichlorethylene, styrene and esters (other than vinyl esters), nitriles and amides of acrylic, methacrylic, fumaric and maleic acids.  The vinyl organic esters are derived from monocarboxylic acids, specified are formic, acetic, propionic, butyric, lauric, benzoic, methacrylic and monochloracetic acids. Specified persulphates are the ammonium, sodium and potassium salts of peroxydisulphuric acid (J.C.S. 1940, pp. 1408-9), and conveniently 4 per cent based on the aqueous medium is taken.  Specified salts of sulphur oxyacids are sulphites, hydrosulphites, bisulphites and thiosulphates, particularly the sodium salts; addition compounds with aldehydes and ketones may also be used, e.g. sodium formaldehyde sulphoxylate.  The amount of the reducing agent used is such that there is present both persulphate and reducing agent throughout a substantial proportion of the polymerization.  The polymerizable material is dispersed and/or dissolved in the aqueous medium, which is preferably weakly alkaline.  Emulsifying agents may be used; specified are soaps, water-soluble salts of sulphonated animal and vegetable fats and oils, water-soluble esters of fatty alcohols and water-soluble colloidal materials, e.g. cellulose ethers.  Preferably the polymerization is carried out in a closed vessel or one from which the air has been displaced by an inert gas, e.g. nitrogen, carbon dioxide.  In example vinyl acetate is polymerized in an aqueous dispersion containing sodium bicarbonate, ammonium persulphate, the sodium salt of sulphated sperm oil alcohols and sodium (1) hydrosulphite, (2) bisulphite, ((5) without sodium bicarbonate), (3) sulphite and (11) thiosulphate, in (6) the dispersion contains ammonium persulphate, sodium hydrosulphite and methyl ethyl cellulose, and in (7) polymerization in ethanol-water solution is carried out. Interpolymers of vinyl acetate and (8) vinyl chloride, (9) methyl methacrylate and (10) acrylonitrile are also described.

Title: Agents for treating molten metal
Inventor: GOODRICH CHARLES BRUCE
IPC: C22C1/04
Filed: 1967-03-20
Abstract: A briquette for the addition of magnesium to molten metal contains in percentage by weight .Mg.4-20 .Fe.0-25 .C.0-2 .Cu.0-20 .Ni.balance and has a porosity of 20%-50% with an average pore size of 50 - 500 microns.  It preferably also has a surface area: volume ratio of at least 8:1. The briquettes are formed from carbonyl nickel powder having a particle size not exceeding 10 microns, iron if present not exceeding 150 microns and magnesium at least 40 microns but preferably not exceeding 1000 microns; the compacts are desirably formed by isostatic compression, as by the use of moulds formed by cup-like cavities in a slab of rubber, a number of such slabs being stacked together in a rubber casing. Sintering must be of the liquid-phase type, and is therefore carried out in the range 510 DEG - 650 DEG C., while to avoid cracking the subsequent cooling rate should be at least 1% per minute.  As exemplified compaction is carried out at 30000 p.s.i. and sintering at 540 DEG C. in hydrogen. The briquettes are primarily used in the production of S.G. iron, but may also be used with nickel, copper or ferrous base alloys for deoxidation, desulphurization, or alloying.

Patent GB-1077661-A (GB)
Title: Treatment of ferrous metals
Inventor: COOK LESLIE
IPC: C21C1/00
Filed: 1962-04-05
Abstract: Iron for the production of castings is produced by melting a solid charge by means of a fuel-oxygen burner, refining by blowing with oxygen in the presence of a lime-based flux and simultaneouly or subsequently recarburizing the metal by the addition of powdered carbonaceous material. The process may be carried out in a converter or in a ladle and the fluxing constituents, which may include fluorspar and iron oxide, may be added at least partially in the oxygen stream.  Carburization may then be brought about by the injection of powdered carbonaceous material such as graphite in an inert gas.  Alternatively carburization and refining may be carried out simultaneously by using separate jets or two passages of a multiple jet; fluxing materials may be dispensed into the oxygen stream and carbonaceous material into an inert gas stream, which may be nitrogen, or all of the solid matter may be added with the inert gas.  Carbon in powdered form may also be added during the melting step to reduce the melting point of the charge; it may be mixed with flux materials or with ferro-silicon.  When carburization is complete any necessary alloying additions may be made, possibly by injection in a stream of inert gas.
