Title: Improvements in or relating to the manufacture of plastics from alginates
IPC: C08L5/04
Filed: 1945-04-25
Abstract: Moulded plastic compositions are produced by taking a moulding powder which comprises a water-insoluble metal alginate, an ammonium-yielding ingredient, water sufficient to make the mixture mouldable and a filler if desired, moulding under heat and pressure, preferably at a temperature of about 100 DEG C. and a pressure of one ton per sq. in. and upwards, and, after moulding, eliminating ammonium alginate from the product.  The alginate is preferably zinc alginate, but ferric, beryllium, aluminium, copper, nickel or cobalt alginates may be used.  The ammonium-yielding ingredient is preferably a salt of ammonia with a weak organic acid, such as ammonium acetate, formate, tartrate or citrate, or 0.880 solution of ammonia may be employed if borates are employed as ammonium alginate eliminating ingredient, these ingredients being substances introduced into the powder to react with ammonium alginate after moulding, and reconvert it to an insoluble form, and may be the borate of an alkali or alkaline earth metal, trioxane, or an alkali chromate such as potassium chromate.  The first Provisional Specification describes also the use of biborates.  The fillers may be woodmeal, metallic powders, oxides, pigments or dyestuffs.

Abstract: 1314598 Electromagnets CLIFTRONICS Inc 22 April 1971 [27 Nov 1970] 10745/71 Heading H1P A rotary solenoid comprises a ferromagnetic housing 12 formed with annular groove 14 in its upper surface within which annular solenoid winding 18 is positioned. A torsion return spring 24 removably and reversably fixed at 28 to the underside of the housing surrounds and acts on a rotary output shaft 26 mounted in central bearing 32. Armature 36 is flexibly hinged to the top surface of the housing 12 under dustcover 38, and its movement is limited by adjustable screw 42 in opening 40. Movement of the armature on energization is converted to rotation of the shaft 26 by positioning ball 46 between opposedly inclined recessed cams 48, 50 formed in a lower surface of the armature 36 and in an upper surface of the shaft 26. The cam in armature 36 comprises first and second conjoined opposedly inclined cam surfaces 52, 54, and in shaft 26 first and second opposedly inclined cams 58, 60; wherein on de-energization the ball contacts surfaces 52, 60 (Fig. 3) with the shaft spring biased for clockwise rotation. Similarly (Fig. 5, not shown) with the shaft spring biased for counterclockwise rotation the ball contacts surfaces 54, 58. On energization the ball is impelled to contact the junctions of the two pairs of cam surfaces at their deepest points, whereby the shaft is rotated in the predetermined sense. A detent may be provided at the junction. Alternatively (Fig. 6, not shown) the armature and shaft may respectively have sunk double cams comprising a 90 degree L.H. section and a 15 degree R.H. section facing 90 degree R.H. section and 15 degree L.H. section; the latter cams extending slightly further into the members or (Fig. 7, not shown) a double armature cam section facing a single shaft cam section or vice versa. Alternatively (Fig. 8) the surface 79 of the shaft 26 may have two pairs of sunk bidirectional cams comprising a 90 degree L.H. cam 80 joining a 15 degree R.H. cam 82 and a 90 degree R.H. cam 84 joining a 15 degree L.H. cam 86; the depressed junctions being indicated at 83, 87 and the pairs of cams being located in diametric opposition. Lines 80A, 82A, 84A, 86A represent the ball centre line in its deenergized position. Other combinations of single and double cams or of differing cam angles are usable.

Patent GB-481465-A (GB)
Title: Improvements in manufacture of diaryl arylene diamines
Filed: 1937-04-16
Abstract: N : N1-Diarylarylene diamines are made by heating an aromatic aminohydroxy compound with at least 2,5 molecular proportions of a primary aromatic amine until the evolution of ammonia is substantially completed, and then heating the mixture further to effect elimination of water; the reaction product is then distilled to recover the diarylarylene diamine.  The proportion of aromatic amine is preferably 5-16 mols. per mol. of aminohydroxy compound, but a part of the excess of amine may be distilled from the mixture after ammonia has been eliminated and before the elimination of water.  The process may be effected in an autoclave or under reflux, and a halide catalyst may be present; specified catalysts are aluminium chloride, ammonium chloride, ammonium iodide, ammonium bromide, ferrous iodide, cuprous chloride, cuprous iodide, zinc chloride, diphenylamine hydrochloride, and dimethylamine hydrochloride.  In an example, p-aminophenol and an excess of aniline are heated in an autoclave with ammonium chloride; ammonia is evolved when the temperature reaches 250-275 DEG  C., and is allowed to escape, with part of the aniline, through a valve which maintains the pressure in the autoclave below 200 lb. per sq. in.; the temperature is allowed to rise to 300 DEG  C., at which point most of the ammonia has been evolved and the evolution of water begins; the temperature is maintained at 300 DEG  C. until no more water is evolved, and the mixture is then cooled and treated with an alkali in a proportion sufficient to convert the combined chlorine into alkali chloride, which is filtered off; the filtrate is then fractionally distilled in vacuo to recover N:N1 - diphenyl - p - phenylenediamine; if the process is effected under reflux, the elimination of ammonia may be effected at about 190 DEG  C. and the elimination of water completed at 220-240 DEG  C.  Other products which may be similarly obtained are N:N1 - diphenyltoluylenediamines, N:N1-ditolylphenylenediamines, N:N1 - dixylylphenylenediamines, N:N1 - dixenylphenylenediamines, N:N1-diphenylnaphthylenediamines, and N:N1-dinaphthylnaphthylenediamines.

Title: Improvements in or relating to enclosed dynamo-electric machines which are cooled by a circulation of hydrogen
IPC: H02K9/24

Abstract: 270,315. Metropolitan-Vickers Electrical Co., Ltd., (Assignees of Penney, G. W.). April 30, 1926, [Convention date]. Void [Published under Sect. 91 of the Acts]. Dynamos and motors, cooling; enveloping in special media; indicators and alarms, applications of.-An enclosed dynamo-electric machine cooled by the circulation of hydrogen has an apparatus connected with the casing for measuring the density of the hydrogen so as to detect. the presence of foreign gas. The pressure developed by a fan running at constant speed in the gaseous medium is utilized to give a measure of the density since the pressure is directly proportional to the density. The Figure shows the invention applied to a turbo-generator having fans 6, 7 which draw the gas from chambers 3, 4 at the rotor ends and discharge into chambers 8. 9 at the stator ends. The cooling medium circulates through passages in the stator core as shown by the arrows and discharge into a pipe 17 from which it passes into the chambers 3, 4 through a cooling device 18. To indicate the presence of oxygen or other heavy gas, a differential pressure gauge 19 is provided comprising two chambers connected separately with the suction and delivery sides of the fan 6 and separated by a flexible diaphragm 20. Excessive pressure denects the diaphragm and closes a relay or indicator circuit 23 which may actuate a valve and permit the cooling medium to escape. A gas pressure device 26 i conjunction with a hydrogen supply 27 may be provided to maintain the minimum pressure at the suction side of the fan preferably above that of the atmosphere. The device comprises a. pair of inverted bells 28 floating in an oil bath and mounted on a beam 31. Pipes 30 connect the upper portions of the bells respectively with the machine and with the atmosphere, and the pointer of the beam has electrical contacts 32 for engaging a solenoid actuating the valve of the hydrogen tank 27. For measuring the purity of the hydrogen beforestarting a separate fan 35 driven by a small motor 36 may be employed. Pipes connect the suction and delivery sides of the fan with the machine and with a pressure gauge comprising a glass tube 42 containing liquid. The glass tube may be calibrated directly in the percentage air admixture in the hydrogen and is preferably provided with electrodes 45 whereby a relay circuit is .closed if the pressure delivered by the fan is excessive. The small fan may be used continually instead of the device 19 and the pressure indicating means may be interchanged. A modified, device for responding to excessive densities comprises a flexible vane arranged adjacent the periphery of the fan so as to be deflected by the impinging stream of gas; the vane closes a relay circuit when flexed to a predetermined amount.
