Title: Paper and process for producing same
IPC: C08F8/00
Filed: 1959-09-28
Abstract: 873,560. Paper &c. made from pulp of high freeness. AMERICAN CYANAMID CO. Sept. 28, 1959 [Oct. 6, 1958], No. 32847/59. Class 96. Paper, e.g. for newsprint or towelling, or cardboard &c. is made from a paper pulp suspension on to the fibres of which has been precipitated a hydrous alumina complex as by the addition of alum, or aluminium chloride, bromide, nitrate or benzoate, followed by alkali, e.g. sodium hydroxide and then, (e.g. at the head box), by e.g. 0.0001 to 0.01% of a water-soluble, anionic, linear carbon chain polymer of molecular weight in excess of 5,000,000 substantially composed of carbamyl alkylene and carboxy alkylene linkages of not more than 4 carbon atoms each, 2 to 20% of which linkages are carboxy alkylene. Rosin size may be added at the beater, after the alum. The aliuninapolymer complex is stated to form practically instantaneously an agglomeration of the fines in the pulp, thereby increasing the freeness of the pulp and thus allowing high-speed paper formation. The pulp may include some fibrillated synthetic fibres, pigments, dyes, and fillers. The invention is applicable to asbestos pulp for making fire barriers, or pipe wrappings &c.

Title: Improvements in epoxide resin compositions
IPC: C08F283/10
Filed: 1953-11-27
Abstract: A synthetic resin composition comprises (1) an epoxide resin, and (2) triallyl cyanurate.  The composition cures on heating, but curing may be accelerated by including a known curing agent for the epoxide resin, e.g. a polycarboxylic acid, an amine, sodium hydroxide or phenoxide, a urea or melamine resin, dicyandiamide or benzyl guanidine, a preferred curing catalyst being a normal alkylamine containing 8-18 carbon atoms.  A vinyl polymerization catalyst for the triallyl cyanate may also be included, e.g. a peroxide or a perbenzoate.  The epoxide resin and triallyl cyanurate may be interacted simultaneously with other copolymerizable ingredients, e.g. styrene, acrylyonitrile, methyl methacrylate or ethyl acrylate, preferably in presence of a vinyl polymerization catalyst.  The composition may also contain a "plastisol" i.e. a finely divided dispersion of a halogen containing vinyl resin (preferably of particle size 10-100 microns) in a plasticizer.  Suitable vinyl resins are polychlorotrifluoroethylene, polyvinyl chloride, polyvinylidene chloride, copolymers of vinyl chloride and vinylidene chloride and copolymer of vinyl halides and vinyl esters (e.g. vinyl acetate or propionate).  Suitable plasticizers are dibutyl phthalate, tricresyl phosphate, dioctyl phthalate, dibutyl sebacate, dinonyl phthalate, di-2-ethylhexyl phthalate or glyceryl monostearate. The plastisol may also contain stabilizers, surface-active agents, other polymerizable ingredients, e.g. diethylene glycol maleate, dipropylene glycol fumarate, styrene, acrylonitrile, diallyl phthalate or methyl methacrylate or other ingredients as disclosed in U.S.A.  Specification 2,567,719.  An exemplified composition comprises 25 parts epoxide resin, 25 parts triallyl cyanurate, and 50 parts of a plastisol which is a finely divided copolymer of vinyl chloride and vinylidene chloride suspended in a dialkyl phthalate. Solutions of the compositions of the invention may be prepared in acetone, cyclohexanone, methyl ethyl ketone and ethylene dichloride to which benzene or toluene may be added.  The compositions or their solutions may be used for surface coating, e.g. for coating metals by dipping; as adhesives; for impregnating cloth, paper, asbestos or mica; for preparing laminated products; as sealants, e.g. for cracked glass surfaces; for potting electrical components; or for coating. The compositions may be moulded with fillers or fillers may be coated with the composition.  Suitable fillers are titanium dioxide, clays, iron oxide, carbon graphite, asbestos fibres, glass fibres, mica flakes or mica powder.  Specifications 518,057 and 579,698, [both in Group IV], also are referred to.

Title: A new or improved calculating instrument, particularly for use in field surveying
IPC: G06G1/14
Filed: 1956-10-30
Abstract: 842,450. Calculating-apparatus. STEPHENSON, H. W. Oct. 30, 1957 [Oct. 30, 1956], No. 33112/56. Class 106 (1). A calculating-instrument for the simultaneous solution of two equations having common variables comprises a base carrying two nomograms representing the respective equations, scales representing values of the common variables being common to the two nomograms, and a slider sliding along one of said scales, an arm being pivoted to said slider and the slider and arm carrying reference lines, the arrangement being such that when the slider and arm are set to given values the required solution of the equation for those values can be read off by means of the reference lines. As described, for the reduction of tacheometric readings by the " Williamson Method," the values of B, the reduced level of the observed point and d the horizontal distance of the point from the tacheometer are found from the relations the additive constant of the tacheometer being taken to be zero. In the relations, a is the vertical angle (i.e. the reading of the vertical circle of the tacheometer), e is the reading of the lower stadia hair, A is the reduced level of the tacheometer, and s is the generating number, i.e. the product of the multiplying constant of the tacheometer (which is 100 in the example described) and the reading of the stadia staff intercept. The instrument is provided with five scales A-E, of which scale A is marked on a slider 2 provided with holes 7 at intervals of five units, through which holes may be seen numbers 0, 5, 10 ... on a flat tape which is moved relative to the scale to provide registration of the reduced level value of the tacheometer with the lower hair setting, usually one foot, on the scale E. The instrument is then ready for use and in operation, a slider 9 is moved in its guides 4, 8 until a hair line 11 thereon registers with the appropriate vertical circle reading α on the scale B. An arm 10 pivoted to the slider 9 is then rotated until a reference line 12 thereon intersects with the appropriate generating number on the scale C. The intersection of the reference line 12 with the scale A then gives the reduced level of the observed point, and the intersection with the scale D gives the difference between the horizontal distance of the observed point from the tacheometer and the generating number. The useful range of vertical circle readings, say - 20 to + 20 degrees, is split up by allotting the range range - 5 to + 5 degrees to an expanded scale and, correspondingly, the scales B, C and D are each provided with two ranges of readings. The scales A, B and C provide a nomogram for the reduced level of the observed point, and the scale D is so arranged that an approximate nomogram for the difference between the generating number and the horizontal distance (which is usually a small quantity) is provided.

Title: Improvements relating to apparatus for producing foam, particularly for fire-extinguishing
IPC: B01F5/06
Filed: 1935-11-29
Abstract: 466,574. Making foam. CONCORDIA ELEKTRIZITATS-AKT.-GES. Nov. 29,1935, No. 33194. Convention date, Dec. 8, 1934. [Class 47 (ii)] A refining device for attachment to a foamproducing apparatus, particularly for fireextinguishing, comprises a tube a in which mixing bodies, such as balls b, are retained between perforated plates c, c<1>. The plate c<1> is slidable under control of an eccentric d, so that the balls can be pressed together and caused to occupy the entire cross-section of the tube, as shown, or can be spread out to leave a part of the tube free. By this means, the consistency of the foam can be varied. The balls may be of glass, or of indiarubber. In the latter case, reduction of the passages between the balls by compression of the balls allows very fine foam to be obtained. In a modification, a holder for the balls b is mounted on the tube a and has a closable connection therewith, so that more or less balls may be admitted to the tube so as to occupy the crosssection thereof to a variable degree.
