Patent GB-1121137-A (GB)
Title: Improvements in or relating to the production of peroxy compounds
IPC: C07C45/30
Filed: 1965-08-06
Abstract: Organic peroxy compounds are obtained by oxygenating unsaturated compounds which are (a) olefin derivatives of the formula R3R4C = CR5-CHR1R2, (b) cisoid compounds of the formula <FORM:1121137/C2/1> or (c) polycyclic aromatic compounds of the formula <FORM:1121137/C2/2> wherein X is an oxygen atom, a propenylene radical or a radical of the formula >C = O or <FORM:1121137/C2/3> where n is an integer, R1 to R13 are hydrogen atoms or electron-donating moieties which are alkyl, alkenyl, cycloalkyl, cycloalkenyl, alkoxy, aryloxy, acyloxy, aryl, aralkyl or aralkenyl radicals which may be suitably substituted and, in (a) or (b), wherein any such group may be joined with any other such group in the same molecule to form a ring, and R14 and R15 are each divalent organic moieties which form an aromatic ring in fusion with the centre ring, provided that no more than one of R3, R4 and R5 is hydrogen, by mixing the organic compound, hydrogen peroxide and a positive chlorine, bromine or iodine compound and isolating the organic product obtained. Suitable positive halogen compounds are hypohalous acids, hypohalites, hypohalite esters, N-haloamides, imides and other N-halo compounds. The process may be carried out in solution, in which case the addition of a water-miscible organic solvent may be necessary, or in a two-phase system using a water-immiscible diluent.  If desired, the primary (hydro) peroxy product may be transformed in situ to some other oxygenated derivative before isolation. The process may be applied to the oxygenation of terpenes and steroids of the formulae (a) or (b) above.
Patent GB-338318-A (GB)
Abstract: 338,318. Frenkel, I. J. Oct. 21, 1929. Cellulose xanthate, making filaments and films from.-The evolution of disagreeable gases in the manufacture of artificial silk and films from viscose is avoided by dissolving nitrocellulose in the viscose during its treatment with alkali. The nitrocellulose is decomposed into cellulose and sodium nitrite which reacts with the sulphuretted hydrogen and other noxious gases liberated in the coagulation bath. A small quantity of hydrazine is formed and it is preferred to add iron salts to the coagulation bath in order to remove the hydrazine in the form of a harmless complex iron salt. In an example nitrocellulose is mixed with cellulose xanthate and caustic soda in an agitator for several hours until completely dissolved, the proportion of nitrocellulose added being about twenty per cent of the amount of alpha-cellulose contained in the xanthate. The proportion of cellulose in the solution is thereby raised from about 7.5 per cent to more than 8 per cent. The solution is ripened and spun into a coagulation bath containing 0.2 per cent of an iron salt such as ferrous sulphate. The filaments are of a chocolate colour when first prepared but after desulphurizing assume the normal colour.

Title: Digitising system
IPC: G01S17/87
Filed: 1974-09-25
Abstract: 1470293 Optical measurement of position CETEC SYSTEMS Ltd 25 Sept 1974 [18 July 1973] 34144/73 Heading G1A The digital co-ordinates of a point on an object, e.g. a map, on a platen are found by two interferometers co-operating with two mirrors; either the interferometers are fixed to the platen and the  mirrors are mounted on a cursor 10 placed over the point, as in Fig. 1, or the interferometers are mounted on the cursor and the mirrors are fixed to the platen as in Fig. 8. The Fig. 8 embodiment allows direct measurement of the co-ordinates by moving the cursor from a reference point and counting the fringes in each interferometer 16, 16A. These interferometers are similar to those used in Fig. 1, but this latter requires triangulation to determine the co-ordinates. In Fig. 1 light from laser 20 passes to interferometers 17, 17A and then via steerable mirrors 18, 18A to reflectors mounted on cursor 10. The reflected light passes back to the interferometers where it interferes with the outgoing light to cause fringes. These fringes are detected by two photo-cells in each interferometer, arranged to have a phase difference of about 90 degrees to give directional information, Fig. 3 (not shown). The photo-cell signals are  counted to give a digital measure of the path length from the interferometers to the cursor, and the co-ordinates are found by triangulation in an associated computer, Fig. 7 (not shown). The computer can give cartesian or polar information, or may show how far the cursor has been moved from a given point. The mirrors 18, 18A in Fig. 1 are controlled by photo-detectors 67, 67A which respond to the reflected light; the mirrors thus track the cursor. If a reflected beam is blocked by an extraneous object this is also detected by the detectors and the computer is disabled; the mirrors are then rotated until the beam is unblocked and tracking resumes.

Title: Improvements in or relating to separable fasteners and to the manufacture of same
IPC: B29D5/02
Filed: 1931-12-09
Abstract: 393,940. Sliding-clasp fasteners. CORNER, G. H. C., 507, Walsall Road, Perry Bar, and LIGHTNING FASTENERS, Ltd., Witton, both in Birmingham. Dec. 9, 1931, No. 34201. [Class 44.] In the manufacture of sliding-clasp fasteners having the fastening members cast directly on the edge of the stringer, the members are formed by moulding from a relatively viscous coldsetting plastic such as quick-setting zinc oxychloride cement, compositions of silicates, artificial porcelain, or hard-setting plastic wood. The material, suitably coloured, is worked up cold to the approximate consistency of pottery clay, and is then formed into beads, each of the size required to form one member. Each bead is then pushed into an aperture in the die. The mould may be slightly warmed before or during the casting process. The stringer tape may be of hairy or plush-like fabric, or may be open weave or net material. A suitable mixture for use in moulding the fasteners may be made by pasting with aqueous solution of acid phosphate or free phosphoric acid a strongly basic aluminium silicate prepared by blending alumina with fluorides and fluosilicates, with or without addition of oxides or hydroxides of calcium, beryllium, strontium, potassium, sodium, silicon, boron, phosphorus and titanium. The basic aluminium silicate should be fused at 1100- 1400‹ C., cooled, and ground to powder before pasting.

IPC: B65H5/06
Filed: 1967-07-26
Abstract: 1,156,960. Feeding sheets. INTERNATIONAL BUSINESS MACHINES CORP. 26 July, 1967 [27 July, 1966], No. 34210/67. Heading B8R. Sheet feeding apparatus includes two coacting freely rotatable balls A and B, first drive means 13, for rotating the balls so that a sheet introduced between them is moved in a first direction, second drive means 14, for rotating the balls so that the sheet is moved in a second direction and means for coupling the balls selectively to the first or second drive means. As shown, a sheet 7 is inserted between sets of balls A and B, whilst balls B are being driven by rollers 13, and is thereby pulled downwards until it abuts the channel 40. Spring 31 which pulls the assembly holding the balls A and B against rollers 13 exerts a pull such that the balls slip on the sheet as soon as it abuts channel 40. A relay may then be energized (manually or automatically) which pulls the ball-holding assembly away from rollers 13 and causes balls A to contact driving belt 14 fed over pressure rollers 18, thereby forwarding the sheet to outfeed rollers 35. In further embodiments belt 14 may have a reversing mechanism for feeding sheets in either direction along channel 40, or channel 40 may be dispensed with and sheets may be selectively fed either straight through or deflected laterally.

Abstract: 733,135. Bottling. SOC. NOUVELLE DES ANCIENS ETABLISSEMENTS F. WENGER and ETABLISSEMENTS VIDUS-HUET & CIE. Dec. 14, 1953 [Dec. 13, 1952], No. 34812/53. Class 125 (2). Apparatus for filling bottles with liquids comprises a liquid reservoir 1 in which a constant level of liquid is maintained by a float 5 and in which a reduced pressure is maintained by suction applied to a connection 2 and filling heads each comprising a sleeve 6 extending upwardly from the reservoir bottom, a conical member 8 disposed over the sleeve and a tube 9 extending into the bottle for conveying the displaced gas into the upper part of the reservoir. In operation, outside air flows through the tube 9 and the liquid inside the member 8 has the level B-B. When a bottle is raised to engage the gasket 12, Fig. 5, at the top of sleeve 6, the reduced pressure draws liquid up between the sleeve and the member 8 and discharges it into the bottle until the level reaches the bottom of tube 9, into which a small quantity enters. When the bottle is lowered, the atmospheric pressure forces down the liquid level under the member 8 and causes the liquid in tube 9 to be forced out of the top and back into the reservoir. In the practical construction, Fig. 5, the gasket 12 is carried by a body 13, the member 8 is attached to the tube 9 and is connected to the sleeve 6 by a bayonet joint 8a and the bottle is guided by a sleeve 11 slidable within the sleeve 6. Ribs 14 space the member 8 from the body 13 and the tube 9 carries a deflector 15 for the incoming liquid. In a modification, Fig. 10, the gasket 12 is carried by a body 19 formed with passages 21, 20 for the liquid flow. A conical member 16 overlies the body 19 and its upper part 17 co-operates with tube 9 to form a restricted, calibrated opening communicating with the gas space of the reservoir. This allows a higher vacuum to be maintained in the reservoir.
