Title: Lighting reflectors
IPC: F21V7/09
Filed: 1945-08-18
Abstract: 595,542. Trough-shaped reflectors. GARRARD, A. Aug. 18, 1945, No. 21130. [Class 75 (ii)] A trough-shaped reflector is so shaped and positioned relatively to a long light source that light reflected from each half of the reflector is distributed over a field extending approximately equally on both sides of the lamp. In Fig. 1, the two sides of the reflector meet at 0 at a reflex angle, each side being formed by a number of circular arcs 0-2, 2-5, 5-6, 6-7, 7-8, 8-9.5 whose centres lie respectively at points (0-2), (2-5), (5-6), (6-7), (7-8), (8-9.5) outside the light source. The curve may, however, be a smooth curve, and the points (0-2) ... (8-9.5) be replaced by a curve of centres which lies outside the light source. In a modification, Fig. 2, the arcs 0-2 and 0-21 meet each other at an acute angle and the sides at a reflex angle, the centres (2-0) and (21-0) lying outside the light source, but each on the opposite side of it from its corresponding arc. In both embodiments, either side of the reflector distributes light over the whole of the field to be illuminated. The surface of the reflector may be formed with a number of shallow irregularities to ensure uniform illumination.

Inventor: SENGER NORBERT GUNTHER BRUNO
IPC: D06P5/12
Filed: 1960-06-16
Abstract: A process for resist-colouration of cellulose textile fabrics comprises applying locally to one side of the fabric a thickened printing paste which contains (a) a nitrogenous resin precondensate and (b) a curing agent, heating to cure the resin and thereafter applying to the same surface of the fabric (c) a water-soluble reactive dyestuff.  Many components are specified; the preferred compounds (a) are 4,5-dihydroxy-1,3-dimethylol-2-imidazolidone and tetramethylol acetylene diurea, and (b) ammonium chloride or nitrate, diethanolamine hydrochloride, ammonium thiocyanate and especially 2,4-dichloro-6-(51-sulpho-11-naphthylamino) -s-triazine.  The printing paste may preferably be thickened with alginates or water-in-oil or oil-in-water emulsions and may contain other additives including methylol stearamide as lubricant or softening agent.  The curing step may be carried out at 140-170 DEG C. and is preferably preceded by drying at 75-125 DEG C. On a preferred embodiment of the invention a water-soluble reactive dyestuff is included in the printing paste.  The dye (c) may be of the anthraquinone, nitro, phthalocyanine and azo series and may preferably contain a dichloro-s-triazine radical.  It may be applied as a medium containing acid-binding agents resin precondensates, thickeners and other known additives by cover-printing or the "nip-pad" process.  Fixation is effected by known methods.  Examples of resist-colouring are given. Specifications 785,120, 785,222, 826,405, 846,505, 850,559, 888,905 and 947,222 are referred to.

Abstract: 440,819. Sharpening razor blades. SUTHERLAND, L., 23, Queens Road, West Gorton, Manchester. July 21, 1934, No. 21361. [Class 60] A device for holding safety-razor blades during sharpening by a grinding stone 14 comprises a block 1, having straight edges 2, 3 at its ends and a projection 4 in its flat surface placed unsymmetrically with respect to the edges 2, 3. A blade 9 is held by headed pins 5 and a rotatable pin 7 slotted at 8, which engage the holes in, or the edges of the blade so that its cutting-edge extends slightly over the edge 2 or 3, the stone 14 then being moved over the cutting-edge whilst resting on the projection 4. In operation, the blade is first placed at the edge 3 and the stone is used to grind away the shoulder 15 from the blade ; the blade is then placed at the edge 2, and since the projection 4 is nearer that edge than the edge 3, the blade is sharpened by movement of the stone 15 over its cutting-edge. The block 1 may have recesses to receive the backing- portion of a backed single-edged blade.

Title: Method of accelerating the speed of sedimentation of solid particles contained in solutions of electrolytes
IPC: C02F1/52
Filed: 1951-09-11
Abstract: Sedimentation of solid particles in brines or solutions of electrolytes is accelerated by adding to the solutions a colloidal carob bean flour solution prepared by heating carob bean flour with water to 70 DEG  to 130 DEG  C., and adding a solution of an electrolyte before, during or after said heating.  The flour may be treated with at least one of the electrolytes contained in the brine to be treated.  For accelerating the sedimentation of clay in a brine containing potassium and sodium chlorides, carob bean flour solution is treated with a solution containing boric acid, sodium hydroxide and potassium chloride.  For a similar purpose or for accelerating the sedimentation of phosphate residues in acid brines containing monocalcium phosphate the carob bean flour solution may be treated with a solution containing boric acid, sodium hydroxide and disodium phosphate.ALSO:Sedimentation of solid particles in brines or solutions of electrolytes is accelerated by adding to the solutions a colloidal carot bean flour solution prepared by heating carot bean flour with water to 70 DEG  to 130 DEG  C. and adding a solution of an electrolyte before, during, or after the said heating.  The added electrolytes which give the best results are stated to be solutions of boric acid and its salts with or without salts of phosphoric acid. In certain cases tannin may be used.  The carot bean flour may be treated with at least one of the electrolytes contained in the brine to be treated.  The method of the invention may be used in the treatment of colliery waste waters.  For accelerating the sedimentation of clay in a brine containing potassium and sodium chlorides, carot bean flour solution has added thereto a solution containing boric acid, sodium hydroxide and potassium chloride.  For a similar purpose or for accelerating the sedimentation of phosphate residues in acid brines containing monocalcium phosphate, the added solution may contain boric acid, sodium hydroxide and disodium phosphate.
