Title: Method of production of synthetic material from starch or starch containing substances
IPC: D01F9/00
Filed: 1947-01-15
Abstract: Film or fibrous material, for use as packaging sheets, strips, filaments, cartons, and the like, is formed by mixing starch or starch-containing materials, e.g. corn, potato, soya, rice, or the like, with water, an additional softener, e.g. a hygroscopic substance such as glycerine, calcium chloride, magnesium chloride, or the like, and/or a flux, e.g. an organic compound having a melting-point above 50 DEG C. such as urea, forming the mixture into a pasty mass, removing excess water and shaping the mass under heat and pressure.  The softener may be present in amounts from 30 to 50 per cent of the weight of the starch.  The flux may be ground together with the starch in a colloid mill.  The starch is preferably gelatinized, before shaping, in the presence of the minimum quantity of water, not exceeding 50 per cent by weight of the starch, this being effected either by rolling the mixture of starch, water, and auxiliary substances between heated cylinders or by extruding through a nozzle having zones of differing temperatures.  Other auxiliary substances such as colouring-materials and fillers, e.g. wood flour or cellulose fibres may also be added prior to gelatinization.  The mass may be extruded into the air or into baths of liquid which do not dissolve starch, e.g. methanol, which do not cause the starch to swell, e.g. acetone, or which act as as softeners, e.g. glycerine. A photochemically sensitive compound such as a chromium or silver compound may be added to the starch to produce a material which can be used in photography, on a material which, after subjection to ultraviolet light, will be less liable to swelling.

Title: Improvements in or relating to plaster moulds
IPC: B28B7/34
Filed: 1943-01-28
Abstract: The moulding surface of a plaster mould for making pottery or (from aqueous dispersions) rubber or synthetic resin articles, is constituted by a thin lining of hard microporous rubber adhering to the plaster mould.  To increase the bond between the plaster and the rubber, re-entrant cavities may be provided in the latter. The lining may be made by thickening (by filtering under pressure) a suitably compounded aqueous dispersion of rubber, applying it with a spatula to a model of the mould, setting the dispersion by means of boiling water or oven heat, vulcanizing, and applying plaster, to the required thickness, to the lining.  When producing a multiple-piece mould, the thickened rubber dispersion is applied to the model, set, cut with a razor at the places where the mould sections are to be separated, bound to the model with fabric, and vulcanized; the pieces are then separated and backed with plaster. If the plaster part of a mould is broken, it can be repaired by applying fresh plaster to the lining.  The aqueous rubber dispersion may comprise "Revertex" (Registered Trade Mark), aqueous dispersion of sulphur and aqueous solutions of casein and calcium formate.

Abstract: 1364791 Conveying and transferring tampons DR CARL HAHN GmbH 12 Jan 1972 [15 Jan 1971] 1484/72 Heading B8A Tampons 1 are transferred from carriers 2 to pre-shaped cups 12 in a foil on a drum 13 by means of an intermediate endless conveyer 8. The carriers 2 are integral with links of a chain 3 which passes around a sprocket 21 (Fig. 2). The latter is coaxial with a sprocket 24 carrying the conveyer 8. Also coaxial with the sprockets 23, 24 is a drum carrying cam tracks 20, 20a. These engage cam follower rollers 18, 18a, each pair of which is mounted on a pusher 17 which carries a pusher rod 5. Thus as the tampons pass around the sprocket 21 they are projected by pusher rods 5 from their carriers 2, into coaxially aligned carriers 7 carried by the conveyer 8. The carriers 7 are conveyed around a drum 10, the periphery of which carries pushers 11. Each of the latter is successively reciprocable by the action of a cam follower 30 rigid with each pusher 11, and a fixed, circular, cam track 29. The pusher 11, at the right moment passes radially outwards through a slot 7g in the carrier 7 so as to push the tampon from its position in a recess 7c of the carrier 7, into a cup 12 of the drum 13. Instead of being shaped as shown in Figs. 4 and 5, the carriers 7 may be formed (Figs. 6-8, not shown) with a flat internal end 7d. Also in this embodiment, the shape of the slot 7g is modified so as to receive a pusher (27b), which is modified in shape with a view to transfer not only the tampon, but also a withdrawal tape.
