The mixture of polymers is formed by conventional dry or wet mixing methods and stabilizers, anti-oxidants or compounds to inhibit chain scission may be included.  The desired shaped article is formed in known manner.  Degradation may be effected with water or specified alcohols containing less than 20 carbon atoms preferably mixed with water optionally in the presence of specified inorganic or organic bases at a temperature typically in the range 100-140 DEG  C. The product may be in the form of bearings, gaskets or filters and may be impregnated with specified lubricants.ALSO:Filters are formed from oxymethylene polymers by preparing an intimate mixture of an oxymethylene polymer resistant to degradation at an elevated temperature by aqueous and/or alcoholic liquids under non-acid conditions and another oxymethylene polymer not so resistant, moulding a shaped article from the polymer mixture under heat and pressure and thereafter subjecting the article to treatment with a non-acid aqueous and/or alcoholic liquid to destroy the oxymethylene polymer not resistant to degradation and endow the article with a cellular structure.

Patent GB-193490-A (GB)
Title: Improvements in and relating to electric switches
IPC: H01H33/55
Filed: 1921-11-23
Abstract: 193,490. British Thomson-Houston Co., Ltd., (General Electric Co.). Nov. 23, 1921. Oil-break switches have an outer vessel 10 containing oil from the insulating cover 12 of which is suspended a pressure accumulating chamber 15 in which the circuit is broken. The inner chamber 15 is built up from a cylindrical metal wall 19 with top and bottom plates, the top plate 16 of insulating material and the bottom plate 18 of conducting material being held together by a number of bolts 25. The chamber thus formed is suspended from the cover 12 by insulated bolts 14 at least one of which conveys the current to the lower plate 18. Centrally secured to the lower side of the plate 18 is an annular conducting member 27 carrying segmental contacts 29 connected thereto by flexible leads 31 and provided with springs 32<1> through which projects the rod 32 which forms the movable contact member. On the upper face of the member 27 is supported an annular conducting member 35 fitting in a central shoulder perforation 34 of the plate 18, the member 35 having an airing surface 36 arranged above the upper contact surface of the contacts 29 and separated from 18 by a ring shaped insulator 30. When the circuit is broken by upward motion of the rod 32, an arc is struck between its end and the contacts 29 which is immediately transferred to the arcing surface 36. The rise of pressure within the inner chamber forces a stream of oil across the arc which is prevented from moving to the upper surface of the plate 18 by a sheet 40 of insulating material. As the movable contact member 32 leaves the upper orifice of the pressure chamber it passes through a passage 51 in the insulator 43 carried by the plate 16, and if the arc still persists a second blast of oil will be directed from the chamber up through this passage and into the path of the arc. The material ejected at the upper orifice is directed by a tube 45 against an insulating baffle plate 46, openings 50 in the cover plate 12 being provided to allow the arc gases to escape. In an alternative construction the lower end of the member 27 may he closed, and lateral openings provided therein for the ejection of the arc gases. An insulating sleeve 41 surrounds the chamber 15.

Patent GB-316315-A (GB)
Abstract: 316,315. Durand & Huguenin Akt.- Ges. July 28, 1928, [Convention date]. Acridine dyes.-Excess of nitric acid is used in the process for making Acridine orange, which comprises nitration of tetraalkyldiaminodiphenyl-methane, reduction of the resulting dinitro to the corresponding diamino compound, forming the acridine ring by elimination of ammonia, and finally transforming the leuco compound so produced to the dyestuff bv oxidation. It is believed that the excess acid, which should not exceed two molecules, attacks the alkyl groups with formation of formaldehyde, which then takes part in the reaction. After the nitration and dilution with ice water, the reduction is effected as in the production of Acridine orange. In a modification of the process, the dinitrotetraalkyldiaminodiphenylmethane is used as the starting material, which is treated with 2 mols. of nitric acid and then reduced etc. as before. According to an example, tetramethyl- or tetraethyl-diaminodiphenylmethane dissolved in sulphuric acid is treated, while cooling, with nitration acid (4 mols.) and the product, after pouring on ice, reduced with zinc dust. Ring closure is effected by heating under reflux, and the resulting leuco compound oxidized by means of ferric chloride. The dyestuff, obtained on salting out, dyes tannin-mordanted cotton red brown tints, and natural silk, copper red shades. It withstands hydrosulphite, and is suitable for direct as well as discharge printing on cotton and silk. In a second example, 3 mols. of nitric acid are used for the nitration and iron shavings and zinc dust used for the reduction. The product gives orange and copper red shades on silk and cotton.

[Class 39 (ii)] Illuminating bodies or filaments are made by coiling helically into compact shape a long thin sleeve or tube having its walls formed of a number of fine wires of refractory metal, woven, plaited, or braided together. For example the wires may be plaited upon a mandrel, preferably of cylindrical cross-section, and then coiled helically upon a secondary mandrel, these mandrels consisting of brass, copper, steel or molybdenum, so that either or both of them may be removed chemically or otherwise, in known manner, after completion of the filament. Alternatively the mandrels may consist of infusible and refractory materials, e.g. asbestos, which are bad conductors of electricity but adapted to emit luminous radiation. The fine wires or component elements of the metal sleeves may be of circular, oval, rectangular, or other cross-section. The example shows a method of forming a metal sleeve by winding wires 1, 2 along parallel helices upon a mandrel a with wires 3, 4 along parallel helices of opposite hand to the first two, these pairs of helices crossing one another. When completed the wires form a closely plaited sheath upon the mandrel, as shown in Fig. 2.
