Patent GB-565011-A (GB)
Title: Improvements in and relating to the treatment of casein or the like protein fibres
IPC: D01F4/00
Filed: 1943-01-25
Abstract: <PICT:0565011/IV/1> <PICT:0565011/IV/2> A tow of casein or like protein fibres is treated with a hardening liquid of specific gravity greater than that of the fibres by continuously feeding the tow in convolutions on to the surface of a bath of the liquid so that the convolutions of the tow float on or in the liquid, allowing the tow to accumulate in the liquid for a sufficient time to produce the desired effect and thereafter continuously withdrawing the tow from the liquid at a rate about equal to the rate of feed by removing the tow from the underside of the mass of convolutions and then conducting the tow out of the liquid through guiding means so that entanglement of the tow is avoided.  To remove the tow from the liquid, it may be conducted through a tube, the entrance of which is situated below the mass of convolutions.  The tube may pass through the side wall of the bath and the exit may be above the level of the liquid in the bath or it may be at or below the liquid level so that a flow of liquid through the tube may facilitate passage of the tow. Pulleys, hooks, or bars may be used for guiding the tow.  The treating liquid may be contained in a cylindrical tank and it may be given a slow circular motion.  A long rectangular tank may be used and a slow current of liquid may be maintained to float the tow along to the exit tube.  The pressure above the tank may be reduced in order to remove objectionable vapours.  The tow may be fed on to the surface of the liquid by traverse feeding mechanism. The tow may be a bundle or thread of continuous filaments or staple fibres derived from milk casein, soya bean protein, or pea-nut protein.  The treatment liquid may effect a preliminary hardening and it may be an aqueous solution of formaldehyde containing a high proportion of sodium sulphate, or it may complete the hardening of the casein fibres and render them resistant to boiling water and boiling dilute acids and it may be an aqueous solution containing sulphuric acid, sodium sulphate, and formaldehyde.  The treatment liquid may be an esterification mixture, e.g. it may comprise acetic anhydride and a liquid such as carbon tetrachloride which is of high specific gravity so that the casein fibres will float on the mixture.  Such an acetylation treatment produces a hardening effect on the casein so that the fibres are more resistant to the action of hot liquids.  As shown in Fig. 1, the feeding device comprises a shaft 1 over which is loosely fitted a tube of glass 4.  The thread passes over the tube 4 and is fed to the surface of the liquid.  As shown in Fig. 3, the thread 6 forms convolutions 8 which float in the liquid 7 and it is continuously removed through tube 9.  Instead of the tube 9, guide hooks may be provided in the treatment bath for leading the thread away from the convolutions.  Specifications 494,184 and 549,642 are referred to.

Title: Improvements in the manufacture of hard or highly viscous materials
IPC: C08L95/00
Filed: 1933-01-14
Abstract: A modification of the process described in the parent Specification for producing a solid electrically-insulating material by making a mixture which is liquid or semi-liquid at normal temperatures and sets at a definite slow rate after mixing and which comprises rosin, a liquid vehicle and a base in the form of an oxide or hydroxide of an alkaline earth or other metal comprises replacing the rosin wholly or in part by certain fatty acids and certain products of the destructive distillation of organic materials.  The fatty acids are those which occur in or are derived from natural oils, fats and waxes and which are substantially insoluble in water and of an oily or wax-like nature; examples are oleic, stearic and palmitic acids.  The distillation products must have a substantial acid content, be capable of mixing with mineral oils, and substantially insoluble in water; examples are pine tar, Stockholm tar, rosin pitch and rosin oil.  In an example, to a mixture of 25 parts rosin, 7 parts stearic acid, 36 parts petroleum residual pitch and 32 per cent transformer oil is added 14 parts of a hardening paste consisting of equal proportions of transformer oil and calcium hydroxide. The mixture slowly hardens.  Five other examples are given.  When the fatty acid or destructive distillation product is liquid at normal temperatures the proportion of the liquid vehicle in the mixture may be reduced.

Filed: 1972-01-12
Abstract: 1380645 Moulding foamed articles CONTINENTAL GUMMI-WERKE AG 12 Jan 1972 [12 Jan 1971] 1370/72 Heading B5A A method of obviating " dome " formation when producing foamed polyurethane blocks comprises using an open topped mould having means for producing a partial vacuum at the edge regions of the mould, i.e. at the edges of the rising foam, relative to the central area. The vacuum counteracts effects such as skin formation and surface tension of the rising foam and produces a block having a flat top. The embodiment shown in Fig. 2 has a stationary mould 1, and a blower 4 which extracts air from the area above surface 2<SP>1</SP> of the foam. A vertically displaceable conduit 5 guides the air flow as shown and produces curved regions 3 at the edges of the block. An induction pipe 6 having an associated valve controls the degree of vacuum produced. Fig. 3 shows apparatus for the continuous production of foamed webs. A conveyer having moving side and base mould walls has fixed conduits 10 at each side spaced from the foam surface by a gap 9, and air entering through the gap is extracted by a fan 12. Fig. 5 shows an alternative arrangement for continuous production in which a closed arrangement is used to continuously recirculate air extracted from the edges of the block by blower 5. A baffle 18 guides the air flow at the edges of the block. In addition to producing flat topped blocks, the method of the invention may be used to produce blocks having ribs on their upper surface.

Title: Improvements in or relating to venetian blind ladder webbing and the like
IPC: D03D1/08
Filed: 1938-03-17
Abstract: 512,835. Fabrics. FRENCH & SONS, Ltd., T., and FRENCH, G. F. March 17, 1938, No. 1449. [Class 142 (iv)] In weaving Venetian blind webbing &c., instead of forming all the cross straps 3 in each row from one set of warp threads as in the usual practice shown in Fig. 1, two or more sets of warp threads, for example three, are used so that the distance along which each cross strap is passed into the webbing may be increased and be independent of the distance between successive cross straps. Thus, after interweaving at 5, Fig. 2, with the weft in the lower banding, one set of warp threads may form a cross strap 6, enter the upper banding at 7, interweave therewith at 8, cross to the lower banding at 9 and interweave therewith at 10 and then repeat. A second set of warp threads forms the cross straps 16, 20 and a third the cross straps 13. As shown, where a set of cross strap warp threads enters an outer banding, it may interchange with the warp threads thereof. Thus at 7 the warp threads 5 of the straps 6 interchange with the warp threads 11 of the straps 16. The entering warp threads may however be superimposed on the other warp threads or both methods may be used. The cross-over parts 18, 9, 15 are cut as usual. In a modification, three sets of warp threads forming straps 27, 9 and 23, Fig. 5, and three other sets forming straps 45, 39 and 59 may be used forming reinforced parts in the outer bandings between 43 and 44 and between 47 and 54 &c. In this case, the two sets of cross straps instead of being staggered, may be placed in alignment as shown in Fig. 6. The intermediate section 64 may be of twill weave. Modifications are decribed wherein a series of lengths of cord braid or narrow tape &c. are used instead of warp threads to form the cross straps. A modification is also described wherein two series of warp threads are used. The cross straps may be wholly or partly weftless, or be woven with weft throughout. There may be only one row of cross straps The straps in one of the two rows may be slightly in advance of those in the other row and allow of a blind lath passing between them. The invention may be applied to webbing used in helmets for holding pieces of cloth or pith.

Abstract: 586,108. Mechanical follow - up devices. VICKERS-ARMSTRONGS, Ltd., and WATSON, J. P. Jan. 16, 1939, No. 1478. [Class 118 (ii)] A mechanical follow-up power system comprises a pair of friction clutches adapted to drive an output shaft in opposite directions, and the normally disengaged. displaceable members of which are moved to engage one or other of the clutches in accordance with the movement of an input or control member by means of an element which is re-set to normal position by the output shaft. As shown in Fig. 1, a control shaft 16 rotates through gearing 15, 14 a screwed sleeve 12 which is prevented from axial movement by abutments 13, but displaces a shaft 10 carrying clutch members 17, 18, one or other of which is thus engaged with oppositely rotating discs 5, 6 geared to motor 1. The consequent rotation of shaft 10 drives the output shaft 23 and causes its own axial displacement to the position in which neither clutch is in engagement. A modification, Fig. 2 (not shown), comprises the use of the cam and scissor-lever devices described in Specification 586,106 for controlling the axial displacement of the shaft 10.
