Title: Method and apparatus for vacuum skin packaging
Inventor: YOUNG WILLIAM EDMUND
IPC: B65B11/52
Filed: 1968-10-02
Abstract: 1,242,726. Vacuum skin packaging. W. E. YOUNG. 2 Oct., 1968 [2 Oct., 1967], No. 46718/68. Heading B8C. A method of packing includes the steps of placing a product 108 to be packaged upon a lower packaging member 104 having an upper surface adapted for heat sealing to an upper thermoplastic film, heating the film to a softened condition for draping, moving the product 108 and the film relative to each other to cause the film to drape over the product, bringing each side of the film to a condition of substantially equal reduced pressure either before or after the film is draped over the product and relaxing the reduced pressure above the film so that the film is urged by the increased pressure against the product and the packaging member to form a heat sealed skin packaged product. In the construction shown the apparatus for carrying out the above method comprises an upper housing member 122 and a lower housing member 126 which co-operate to form an hermetically sealed chamber, means for moving the housing members relative to each other, to close and open the chamber and fluid conducting means 134, 144 for evacuating and venting to atmosphere the chamber. Means are provided for feeding a strip 106 of thermoplastic film between the housing members 122, 126 to form the upper thermoplastic film and means 120 for heating the film to warm the film to a draping condition. Means for feeding the lower packaging member 104 having the product 108 thereon to between the housing members 122, 126 are provided such that on the bringing together of the housing members or on moving the product into the film (Figs. 1 to 9, not shown) the film drapes about the product. Both sides of the film within the chamber are brought to substantially the same reduced pressure and then the upper part of the chamber is vented to atmosphere closely followed by the venting of the lower part. The strip 106-is fed to the chamber between continuous roller chains 114 and cooperating endless belts 115. A supplementary heating means may be provided within the chamber. The sealed package is transferred to a severing end discharge station 128 where by means of a hot wire trimmer 166 the package is cut from the film 106 and passes on a platform 170 from the line of movement of the package carrier 102. In a further embodiment (Figs. 1 and 15, not shown) the lower package member is formed from a continuous film which passes through the apparatus. The chamber may be formed of two or three parts (Figs. 1, 2, not shown), heaters being pivotally mounted in the upper housing member (Figs. 1 to 5, not shown) or mounted in the lower housing member (Figs. 6 to 8, not shown).

Title: Production of light-weight concrete products
Inventor: BOWLIN GABRIEL PETER
IPC: C04B28/26
Filed: 1964-11-20
Abstract: Light-weight concrete is produced by moulding and drying an aqueous admixture of Portland cement, an inorganic calcium salt, sodium silicate and pretreated fibrous cellulosic material, the cellulosic material being pretreated by saponification with alkali metal hydroxide, washing and drying.  A mixture of calcium carbonate and calcium chloride may be employed as calcium salt. The concrete products may be cured by subjecting them to a heating and cooling cycle to a maximum temperature of 180 DEG  F. for several hours.ALSO:Cellulosic fibres are treated for use as concrete additives (see Div. C1) by saponification with alkali metal hydroxide, washing, and drying free of surplus moisture; the resulting fibres are substantially pure cellulose.  The process is applicable to crude or partially refined fibres such as sugar cane bagasse, branches and leaves of trees and plants, bamboo and wood shavings, and hemp fibres.  The fibres may be cut up, and then boiled with an aqueous solution of NaOH containing 1 - 3 lbs NaOH per 50 gallons water for 10 - 30 mins; the floating foam is skimmed off, the fibres rinsed with water, pressed, and then further dried, e.g. by warm air, to 5 - 20% moisture content.

Title: Process for controlling dusting of solid powdery materials
IPC: B01J2/30
Filed: 1972-10-17
Abstract: 1413329 Controlling dusting of powdery materials KEWANEE OIL CO 17 Oct 1972 [19 Sept 1972] 47744/72 Heading C1A [Also in Division C4] Dusting of a normally high-dusting solid, powdery material other than polytetrafluoroethylene resin is controlled by mixing the material with an effective amount of particulate fibrillatable polytetrafluoroethylene resin, working the mixture at a temperature at which fibrillation of the polytetrafluoroethylene resin can occur until the desired amount of dust control is achieved, and recovering the product as a powder having a particle size at which, without such treatment, the powder would exhibit highdusting characteristics. The working involves a masticating action without necessarily effecting a change in the primary particle size, e.g. by gentle simultaneous shearing and mild compacting action, by kneading action or during spray drying. In a modification a dispersion of the material in a liquid having dispersed therein an effective amount of particulate fibrillatable resin is spray dried at such a temperature and in such a manner that fibrillation of the resin occurs. In the examples various pigments are rendered essentially non-dusting by (1-15) slurrying the pigment in a hot liquid processing aid (water or mineral spirits) to yield a smooth slurry, adding fibrillatable PTFE resin, blending manually or in a mechanical blender, filtering, drying and gently working in a slow speed electric mixer or by manually spatulating the material; (16-18) dry-blending the pigment with fibrillatable PTFE resin in a blender and working in a pug mill, a mixer or manually ; and (19-22) spray-drying a slurry of the pigment, a liquid processing aid and fibrillatable PTFE resin. In Examples 23-26 potassium fluoroborate powder is blended with PTFE and mineral spirits and gently worked.

Title: Processing of olefin polymers
Inventor: HOUSER CLARENCE G
IPC: C08F10/00
Filed: 1963-12-12
Abstract: Olefin polymers which can be processed into substantially streak-free film are made by catalytically polymerizing at least one mono-1-olefin to a solid polymer and treating it with a diketone to remove catalyst residues, and then contacting the treated product with water vapour at a temperature of from 220 DEG  to 275 DEG  F. for a period of time sufficient to yield a polymer product which when extruded into film will produce a substantially streak-free film. The water vapour may be mixed with an inert gas. The catalyst is generally of the Ziegler-Natta type.  The 1-olefin may be ethylene, propylene, 1-butene, 1-pentene, or 3-methyl-1-butene. The process may be effected continuously and the polymerization effected in the presence of hydrogen.  The Specification contains a long list of diketones of which acetylacetone is preferred. The Specification also describes in detail a continuous bulk process of carrying out the process and illustrates it with a flow diagram.
