Title: Improvements in or relating to the treatment of polymeric materials
IPC: C08K5/17
Filed: 1943-08-31
Abstract: The tensile strength of a vinyl chloridevinylidene chloride copolymer prepared from 10 to 25 per cent of vinylidene chloride and 90 to 75 per cent of vinyl chloride is increased by incorporating an amine therein and heating to 240-360 DEG  F.  Their solubility in solvents such as methyl ethyl ketone and tendency to cold flow are also reduced.  Amines specified are hexamethylene tetramine, monomethyl and monocyclohexyl propylene diamine, m-phenylene diamine, di-3-aminopropyl methylamine, sym-dicyclohexyl dipropylene triamine, monohexadecylamine, triethylamine, tributylamine, triamylamine, triethanolamine, di - 3 - amino - propyl ether, morpholine, piperidine, piperazine and dibenzylamine.  There may be added acid acceptors, e.g. magnesium oxide, calcium oxide and sodium carbonate, plasticizers, e.g. dibutyl sebacate, methoxyethyl oleate, dioctylphthalate and tributyl phosphate, and pigments, e.g. carbon black.  In an example, granular or powdered copolymer is hot milled with dibutyl sebacate, magnesium oxide and carbon black, the mill is cooled, hexamethylene tetramine milled in and the composition sheeted out. The sheets were then present at 320 DEG  F. under 1500 pounds per square inch pressure.  Symdicyclohexyl dipropylene triamine is prepared by reacting equimolar proportions of cyclohexylamine with acrylonitrile and reducing with hydrogen.  Di - 3 - amino - propyl ether is prepared by reducing di-cyano ethyl ether with hydrogen. Di-3-aminopropyl methylamine is prepared by condensing acrylonitrile with methylamine and reducing with hydrogen.

Abstract: 146,392. Ammann, O. Feb. 25, 1918, [Convention date]. Computing scales for gunnery calculations. - A gunnery calculator for showing the relations bet w e e n quadrant elevations, heights of targets and other quantities comprises a transparent or other card on which are drawn curves L connecting points of equal heights on the trajectories represented in the plan bv lines a, b, c, d radiating from the gun position A to an arcuate scale p of quadrant angles. Fig. 1 shows the trajectories in elevation to illustrate the manner in which the " contour lines " L are obtained by projection. Lines such as f joining points of equal time flight, angle of descent or other quantities may be superposed. By means of a linear seale the distance between adjacent contour lines may be converted into angles of descent. Instead of actually drawing a number of trajectories an arm pivoted at A and graduated in ranges may be employed. In a modification the trajectories and curves are plotted in rectangular co-ordinates and a parallelmotion straight-edge substituted for the radial arm. According to the Specification as open to inspection under Sect. 91 (3) (a) the curves may be plotted with inclined co-ordinates, or for plotting results upon a map the trajectories may be drawn in elevation upon a penetratable transparent plate as in Fig. 1 but with polar coordinates so that the trajectories are spaced out to give clearer reading. Fig. 8 (Cancelled) shows a board provided with two charts, a radial range arm, and a scale for conversion of the distances between " contour lines " into angles of descent. This subject-matter does not appear iu the Specification us accepted.

Patent GB-1076125-A (GB)
Title: Improvements in or relating to the waterproofing of fabrics
IPC: D06M15/263
Filed: 1965-04-08
Abstract: Woven or knitted fabrics capable of absorbing water at ambient temperature in an amount of not less than 90% of the weight of the dry fabric are waterproofed by coating at least one surface of the fabric with a first synthetic resinous material, the liquid absorptive power of the fabric being reduced by a preliminary treatment in which the fabric is impregnated with a second synthetic resinous material having an affinity for the first synthetic resinous material in an amount such that there is present in the dry preliminarily treated fabric 0.8 to 4% of the second synthetic resinous material whilst the softness and feel of the fabric are not affected.  The fabric may be made of natural fibres, or of a mixture of natural and synthetic fibres.  In the examples, fabrics of cotton fibres, and mixed cotton and polyester fibres with plain weave are used.  The second synthetic resinous material may have a linear or two-dimensional structure and may be acrylic, vinyl, urea, melamine resins.  The first synthetic resinous material may be resinous material capable of further polymerisation to form a three dimensional structure and may be an acrylic, or modified acrylic, polyurethane, or polyester resin. The two resinous materials may interact such that one is a plasticizer for the other to make say the coating more flexible. A repelling component e.g. a silicone, may be added to the second synthetic resinous material to attain a predetermined equilibrium condition between the receptivity and repellency of the fabric towards the resinous material subsequently used to coat the fabric.  It is thus possible to control and restrict the absorbing power toward the resinous material in the coating.  The preliminary treatment may be carried out by impregnating with a dilute solution of the resin e.g. acrylic resin in ethyl acetate, and then removing the solvent.  The impregnation may be carried out in vats or baths, or by spraying.  The repellent material may be added simultaneously as a solution in say hexane.  The coating may be applied by say blade-spreading, calendering, spraying, casting.  The coating may then be dried to remove solvent and promote further polymerization.  Multiple coatings may be applied with or without intermediate drying.  Finishing coats may be applied, e.g. a silicone coating, on one or both sides of the fabric.

Abstract: 749,012. Electric indicating systems. SPERRY GYROSCOPE CO., Ltd. May 13, 1954 [May 28, 1953], No. 14874/53. Class 40(1) An alarm is operated according to the magnitude of the lack of correspondence (isogonalisation error) between the indicating elements or shafts driven by two identical navigational instruments. As shown Fig. 1 a system comprising a gyromagnetic compass G1 driving a remote indicator X1 through a known form of transmitter Tl e.g. servo controlled, is duplicated at G2, T2, X2, the isogonalisation error being measured by a mechanical differential 14 which drives an indicator 16 in accordance with the differential displacement of the two transmitter shafts 12, 13. The indicator may operate a visual or audible alarm at some predetermined error value. The differential may, alternatively be electrical and fed from synchro devices driven by the respective transmitters, Fig. 1A (not shown). In another embodiment, Fig. 2, the isogonalisation error is indicated by a synchro system, the transmitter rotor R1 of which is driven by the transmitter T1 and energized from a source 24. The stators S1, S2 are coupled in the usual way and the receiver rotor R2, driven by the transmitter T2, is mounted on its shaft at right angles to the rotor R1-when the error is zero-so that a centre zero instrument 25 connected to the rotor R2 will indicate the magnitude and sense of the error. This error detecting arrangement may be actuated from the remote indicators X1, X2 instead of the transmitter T1, T2 Fig. 3 (not shown) and in either case, instead of mounting the rotors R1, R2 at right angles, they may be mounted parallel to each other and the necessary 90 degree phase displacement effected by:- (a) a differential synchro connected between the stators S1, S2 Fig. 4 (not shown), (b) an autotransformer connected between the stators Fig. 5 (not shown), (c) using resolver type synchros and cross connecting the stators thereof, Fig. 6 (not shown), (d) using synchros having two rotor windings mounted at right angles, Fig. 7 (not shown).
