Patent GB-1093314-A (GB)
Title: Improvements in or relating to the formation of felt
IPC: D04H17/00
Filed: 1966-01-26
Abstract: A method of felting a preformed felt bar, or a mass of fibres packed into a flexible bag for formation into a felt bar, comprises restraining the bar substantially parallel to the face of a felting hammer which strikes the felt, or fibrous mass, to effect transverse compressions thereof, the position at which the bar is struck by the hammer being varied, preferably by intermittent or continuous rotation of the bar.  The felting is preferably carried out by a pair of hammers arranged to strike the bar alternately in mutually perpendicular directions.  When felting a tube of felt, a core is positioned within the felt, which core may be hollow and initially expanded by fluid pressure which is reduced as the diameter of the material decreases. Apparatus comprises a pair of hammers and associated anvils, the hammers striking substantially at right angles.  The hammers are connected by a link so that when one hammer moves towards its anvil, the other moves away from its associated anvil, one hammer being connected to a reciprocating drive means. The distance between the hammer and its anvil may decrease in the direction of feed of the felt bar for the continuous felting or forming of felt bar or tubes.  In the case of continuous formation of felt tubes a fixed progressively decreasing core may be provided between the hammer and its anvil.  The apparatus may include a series of pairs of hammers arranged to strike at 45 DEG  to the positions of strike of the preceding pair.

Title: Method for the production of cellulose from maize stalks or other grasses
IPC: D21C3/06
Filed: 1938-02-04
Abstract: 510,716. Food for animals. DORNER, B. Feb. 4, 1938, No. 3592. [Class 5 (ii)] [Also in Group IV] Forage is obtained as a by-product during the production of cellulose for paper-making from maize-stalks, straws, and grasses. The raw material is washed, mechanically disintegrated until it assumes a hay-like state, and then further disintegrated in a rag-engine until the bulk of the non-cellulosic organic matter is in the form of a slime which is then removed by the filter-drum of the rag-engine. The slime is submitted to settling or centrifuging to separate the water and the residue is used for forage. The fibrous material and parenchyma are then removed from the rag-engine and submitted to a boiling underpressure in presence of sulphurous acid. The parenchyma reduced to powdered condition by the chemical treatment is then separated from the fibrous material and may be used as forage. Separation may be effected by floating the material in water on to an endless screen belt, the fibrous material remaining on the belt, and then centrifuging the parenchyma suspension or allowing it to settle. The quantity of forage material from the rag-engine may be increased by passing steam through the materials and neutralising with alkali. After removing the slime, the liquid is acidified, whereby a precipitation of more organic material suitable for forage is obtained. The quantity of forage obtained in the boiling step may be increased by effecting a. more vigorous treatment, subjecting the material to a further boiling after adding alkali and effecting a rapid bleaching. On acidifying the liquid after the alkali treatment, pentosans are precipitated in colloidal form. These may be centrifuged with or separately from the other colloidal organic byproducts and used for forage.

Abstract: 139,582. Boddy, G. M. Feb. 17, 1919. Body attachments, buoyant. - In reversible life-saving appliances comprising front and back compartments of substantially the same amount of buoyancy, the compartments are constructed, and filled with buoyant material, such as kapok, cork, or reindeer hair, so that they have a maximum buoyancy at the bottom and a minimum at the top, whereby the buoyancy is not materially impaired, in case the top of the compartment is not immersed. In the form shown in Fig. 2, the compartments 1, instead of being approximately rectangular, are made considerably wider at the bottom 3 than at the top 2. In the modification shown in Figs. 4 and 5, which may be combined with that shown in Fig. 2, the compartments 4 more nearly approximate to the rectangular form, but are made substantially thicker at the bottom 5 than at the top 6, as shown in side view in Fig. 5. Additional buoyant compartments may be suitably attached to those above-described. The buoyant material may be secured in position within the compartments by stitching through the material, or by smocking &c.

A thermoplastic bottle crate is moulded in one piece to have bottom, top, side, and end walls, 1, 2, 3, 4 respectively, and the bottles are separated by apertures 2A, with skirts 2B, in the top wall, and walls 5, 5A, 6 formed integrally with the bottom wall, parallel to the side walls. The walls 5, 5A, 6 have high points 12 at their intersections and lower points 11 therebetween, and run down into the bottom wall at their ends 13, see Fig. 4, At certain of the high points the walls connect with projections 8 depending from the top wall to form reinforcing struts, and these have holes 20 which assist drainage during washing of the crate, as do holes 19 in the bottom wall 1. The end walls 4 have hand holes 15 in recesses 18 and the walls 5A, adjacent the ends have low points 11 not so low as in the walls 5, and 6, to provide more strength. In a second embodiment, Fig. 7, the walls 5, 5A, 6 are absent and the bottles are spaced by ridges 36 surrounding flat square, or V-shaped, areas 37A level with the crate bottom. The skirts of the apertures in the top wall may be deeper and have vertical slits so that they grip the bottles more firmly. In further embodiments the bottle separators are projections of various kinds integral with the top and/or bottom walls. A preferred separator is shown in Fig. 16 and has a frusto-conical top portion and a cruciform lower part which provides support for the bottles.

Title: Improvements in or relating to composition comprising vinyl fluoride polymers
IPC: C08K5/098
Filed: 1959-02-06
Abstract: Vinyl fluoride polymers are stabilized by the incorporation of an alkali metal formate, e.g. sodium, potassium or lithium formate.  The polymer composition must be free from peroxidic compounds.  The polymer may be a homopolymer or a copolymer of a major proportion, preferably at least 85% wt. vinyl fluoride, with, for example, vinyl chloride, ethylene or tetrafluoroethylene.  It is preferred that the inherent viscosity of the polymer is at least 1, and for the formation of self-supporting films 2.5 to 4.5.  1 to 10% wt. of formate may be added as an aqueous solution to an aqueous polymer dispersion, which, after filtration and washing losses yields 0.1 to 1% wt. of formate in the dry polymer.  The polymer composition may also contain other resins, plasticizers, pigments, fillers and other conventional ingredients.  The compositions may be used to form films, foils, sheets, ribbons, bands, tubes, coatings, laminates, fibres and filaments.  Specifications 605,445, 653,822 and U.S.A.

Title: Oriented films of substituted oxacyclobutane polymers
IPC: B29C55/00
Filed: 1955-02-14
Abstract: Unsupported molecularly orientated films are made from polymers of 3 : 3-bis-(chloromethyl)-oxacyclobutane, the polymers having a specific viscosity greater than 0.3 when measured as a 0.1 per cent solution in cyclohexane at 50 DEG  C. (corresponding to a molecular weight of at least 10,000).  Sheets or ribbons of the polymer are extruded at 160-260 DEG  C., rapidly quenched to 0-80 DEG  C. within one minute, preferably within 10 seconds, and then subjected, at 0-50 DEG  C., to strain in one direction or, either simultaneously or in succession, in two directions substantially at right-angles to each other. Alternatively, the films may be prepared by solvent casting, fused at 160-260 DEG  C. on a chrome plate coated with a silicone oil to prevent sticking, and then orientated by drawing as already described.  The film, prepared by either process, may then be heat-set at 60-125 DEG  C.  Stabilizers may be added to the polymer against, for example, the action of light or heat, and phenols are suitable for this purpose; a long list of suitable phenols is given. Plasticizers may also be added, and many alkyl esters, oils, polyethers, and halogenated hydrocarbons are specified.  If desired, pigments may be incorporated before the formation of the film.  The process may also be applied to copolymers of 3 : 3-bis-(chloromethyl)-oxacyclobutane with other 3 : 3-disubstituted oxacyclobutanes, and several such copolymers are described. Specification 758,450 is referred to.  Reference has been directed by the Comptroller to Specification 723,777.
