Patent GB-795894-A (GB)
Title: Alkoxysilylpropylamines
IPC: C07F7/18
Filed: 1956-01-16
Abstract: Fibrous glass material is sized or finished by applying thereto a solution obtained by adding an alkoxysilylpropylamine having the formula: <FORM:0795894/IV (b)/1> where R is an alkly group, R1 is a hydrogen atom or an alkyl or aryl group, and x and y are each 0, 1 or 2, to water or to aqueous organic mixtures.  In solution, the silanes are converted to aminopropylpolysiloxanes.  The treated glass fibres are particularly useful for the preparation of reinforced plastics, e.g. laminates.ALSO:The invention comprises alkoxysilylpropylamines of the formula <FORM:0795894/IV (a)/1> where R is an alkyl group, R1 is a hydrogen atom or an alkyl or aryl group, and x and y are each 0, 1 or 2.  They are prepared by reacting ammonia with a gamma-chloropropylalkoxysilane at a temperature of at least 90 DEG C. and at superatmospheric pressure. The products are mixtures of mono-, bis- and tris-amines, the proportion of monoamine being greater with greater mol. fractions of ammonia in the reactants.  The proportion of reactants may vary from about 1 to 20 mols. of ammonia per mol. of silane.  The compounds are hydrolysable to siloxanes which form clear, stable solutions in water or in aqueous organic mixtures which are useful as sizes for fibrous glass material.  The compounds may also be reacted with compounds containing methylol groups and the products subsequently hydrolysed.  In the examples: (1) gamma - chloropropyltriethoxy silane (0.3 mols.) is heated with ammonia (3.0 mols.) at 100 DEG  C. under autogenous pressure, and a fraction of the product is identified as mono-(triethoxysilylpropyl)amine; (2) the mono-, bis-and tris-(triethoxysilylpropyl)amines are identified after a similar reaction as in (1); (3) 50 per cent yield of the mono-amine is obtained using 20 mols. of liquid ammonia per mol. of silane; (4) the mono-amine is hydrolysed in water and the polysiloxane is obtained in glassy and in powder form, both of which form clear solutions in water.  The Specification also discloses an aminopropylmethyl polysiloxane and a dimer of aminopropyldialkyl siloxane.

Abstract: 498,359. Variable - speed gearing. GREGOIRE, P. J. Jan. 15, 1938, No. 1389. Convention date, Jan. 20, 1937. [Class 80 (ii)] Automatically-variable epicyclic gearing comprises a pair of planet pinions 5, 6 carried by a driven (or driving) member 2 and meshing with a driving (or driven) annulus 1, the pinions having crank arms 7, 8 which are of different lengths but which are always parallel to each other. The cranks are connected by rods 15, 16 to points 13, 14 on a lever 12 pivoted to one end 11 of a lever 10 pivoted on the member 2. A spring 17 is interposed between the other end of the lever 10 and an adjustable abutment 18 on the member 2.

Patent GB-1536474-A (GB)
Title: Method for the manufacture of twistless or substantially twistless yarn and yarn manufactured by the application of that method
IPC: D01F6/14
Filed: 1976-01-15
Abstract: 1536474 Drafting; false twisting and autogeneously bonding sliver; autogeneously bonded composite yarn HOLLANDSE SIGNAALAPPARATEN BV 15 Jan 1976 [10 Feb 1975] 01642/76 Headings D1F and D1W A twistless or substantially twistless yarn is produced by forming a fibre strand comprising an assembly of staple fibres and a potentially adhesive fibre component, at least the staple fibre assembly having been wet drafted, false twisting and supplying liquid to the strand, and thereafter bonding the strand by activating the, potentially adhesive component by heating the strand. in a confined space in which an equilibrium is reached between the liquid content in the strand and in the surrounding space and then drying the strand after it has left the confined space. Preferably the strand is a sliver. The heating may be accomplished by passing the' sliver through a tube situated in the resonant cavity of a radio-frequency furnace. Alternatively the sliver may be passed over a drum partly covered by a shield and either the drum or the shield is heated. If the shield is heated contamination of the drum by the adhesive component is reduced. The drum surface may be of polytetrafluoroethylene in order to reduce contamination. Only a small amount of moisture has to be evaporated from the sliver to saturate the tube or the space between the drum and the shield. This allows rapid heating of the sliver to above 70C without undue loss of moisture, thereby attaining the optimum conditions of moist heat for activating the adhesive component and maximising the yarn strength. The bonded sliver is pre-dried, i.e. its moisture content reduced below the point at which the adhesive component is activatable, on the unshielded portion of the drum or after leaving the radio-frequency tube. It is then wound on a bobbin and dried. The sliver may comprise multicomponent staple fibres in which at least one component is potentially adhesive, such as specially netted flax or a synthetic fibre with a polyvinyl alcohol sheath, or a mixture of non adhesive fibres (e.g. cotton, viscose rayon, polyester, polyacrylonitrile and stabilised polyvinyl alcohol) with hot moisture activatable fibres (e.g. alginate fibres or fibres or a continuous filament of unstabilised polyvinyl alcohol) or hot organic solvent activatable adhesive fibres (e.g. cellulose diacetate and triacetate). The continuous unstabilised polyvinyl alcohol filament is preferably added at the last rollers of the sliver drafting means.

Title: An improved process for the continuous production of hollow articles of plastic material
Inventor: JEAN CARDOT
IPC: A61J1/06
Filed: 1952-01-23
Abstract: 757,691. Making ampoules &c. SOC. ANON. DES MANUFACTURES DES GLACES ET PRODUITS CHIMIQUES DE ST.-GOBAIN, CHAUNY ET CIREY, Jan. 23, 1952 [Jan. 23, 1951], No. 1893/52. Class 56 [Also in Group V] Successive portions of a moving tube of plastic material are enclosed in a mould and sucked against the walls of the mould. Figs. 5 to 7 illustrate a three-stage method of making ampoules in which (1) an extruded tube 2, which may be of glass, descends between two open mould halves 3, which are then closed around the tube as in Fig. 5. Each mould half is carried by a jacket 5 pivoted at 10 (Fig. 8). (2) Suction is applied to the mould space 8 through passages 7, 6, 9; whereby the tube takes the shape of the mould (Fig. 6). During this suction stage two fingers 11 descend to draw out the lower point of the ampoule 12 being made (3). The mould is opened (Fig. 7) and a second pair of fingers 14, initially disposed above the mould, descend and draw the formed ampoule down, the fingers 11 being moved aside. The fingers 11, 14 then move back to the Fig. 5 position and the sequence is repeated. The ampoules thus moulded, form a chain, and may be separated from the chain (as shown, in pairs) by a blowpipe 15 which also seals the ends. The chain may be cut into long lengths, all the ampoules therein being later filled at the same time. As shown, the mould is hexagonal in cross-section and volumetric graduations A are formed on the ampoule. If the mould jams it may be prised open by inserting a tool into a gap 10a between the halves. In a modified process, Fig. 9, the extruded tube is engaged by a series of travelling moulds, one mould being shown in five successive positions. Between the third position 19b and the fourth 19c,  the mould moves faster than the extruded tube, whereby the neck portions are drawn out. In another modification (Fig. 10, not shown) for making flat-bottomed bottlelike ampoules, cutting edges on the base of the two mould parts form the flat bottom of the ampoule. Flasks and bottles may be made. The direction of extrusion may be upward or in a direction inclined to the vertical.
