Title: Production of anhydrous sodium metasilicate
Inventor: MOCKRIN ISADORE
IPC: C01B33/32
Filed: 1956-05-25
Abstract: Anhydrous sodium metasilicate in the form of filterable crystals, e.g. 30-40 microns in size, is prepared by adding caustic soda, preferably aqueous or fused, to a silicate solution consisting of 11-22% Na2O, 24-38% SiO2 and 42-60% H2O to provide a liquid composition consisting of 27-42.5% Na2O, 10-22% SiO2 and 43-60% H2O which is heated to and maintained at at least 140 DEG  C., e.g. 160-200 DEG  C. to precipitate said crystals.  The initial silicate solution may be prepared by digesting silica, e.g. a -quartz or sand in aqueous caustic soda, preferably at a temperature of 130-150 DEG C. for two hours and then at at least 180 DEG  C. to avoid iron contamination from the reaction vessel.  The liquor remaining after removal of the crystalline precipitate may be used in forming the initial solution.  The solution from which the crystals have been precipitated may be cooled to 80-100 DEG  C., and after separation by centrifuging or filtration the crystals are preferably washed with a hot aqueous solution containing 35-40% sodium metasilicate. Thereafter the crystals may be dried, preferably in an atmosphere free from CO2.  In the example, the process (starting from silica and sodium hydroxide) is performed in an autoclave equipped with a stirrer and pressures of 110 and 52 p.s.i.g. respectively are generated in the formation of the two sodium silicate solutions at a temperature of 180 DEG  C.  Both in the initial mixture and the components forming the pregnant solution, sodium nitrate was present. The product was dried at 150 DEG  C.  It is stated that if the silicate solution is added to the caustic soda instead of vice versa, the crystals which separate are finer and more difficult to separate from the mother liquor.

Filed: 1948-06-22
Abstract: 649,366. Fixing bristles in brushes. TETLEY, T. H. June 22, 1948, No. 16740. [Class 19] In a method of mounting bristles of fusible material, for example nylon, for the manufacture of a brush, the bristles are assembled in a metal or other heatproof holder of tubular shape one end of which is flared or bell-mouthed, and heat is applied to the holder in the region of the flared part to fuse the ends of the bristles at that part to form a solid mass on cooling. In the Figures showing the construction of a shaving brush the bristles are assembled in a tubular holder 1 and trimmed level with the bell-shaped end 2. The holder is then clamped upright by means of clamp 3 and the bell-shaped end is heated, e.g. by means of a flame 5 causing the bristles to fuse whilst gases escape through the holes 6. On cooling the fused portion of the bristles a hard, solid stock 7 results. The tube 1 is removed, the stock trimmed to fit an annular piece 10 which is passed over the bristles to engage it. The annular piece 10, the stock 7 and the handle 8 are then cemented together. The manufacture of brushes of other cross-sections, e.g. oval or rectangular is mentioned. Specification 550,229 is referred to.

Title: Improvements in or relating to epoxy resins
Inventor: HOWE BRIAN RUSSELL
IPC: C08G59/08
Filed: 1954-06-09
Abstract: Epoxy resins soluble in ketones and hydrocarbons are obtained by reacting a styrenated oil-insoluble novolak resin with a haloepoxy alkane, e.g. epichlorhydrin.  The styrenated novolaks are produced as described in Specification 750,286.  Catalysts for the reaction are acids, e.g. sulphuric, hydrofluoric, fluorosulphonic acids; borofluoro acetic acid complexes, stannic chloride, boron trifluoride and their complexes; mixtures of boric acid and dicarboxylic acids or hydroxycarboxylic acids; dihalohydrins may be used instead of the epoxyalkanes.  The etherification reaction is carried out by adding the alkali in stages.  The resins obtained may be cured with the usual agents, e.g. polyamines, amides and carboxylic acids.  In examples: (1) 100 parts phenol mixture containing 50-52 per cent cresol and conforming to Grade C.B.S.S. 521/1955, 64 parts 40 per cent formalin and 0.6 parts oxalic acid in 1 part water are refluxed and distilled under vacuum at 80 DEG  C.; 500 parts of the novolak thus obtained are melted with 500 parts styrene and after distillation to remove water are reacted in presence of 1.2 parts boron trifluoride acetic acid complex; 200 parts of the styrenated novolak are dissolved in 465 parts epichlorhydrin and reacted with the addition of 6 parts of NaOH pellets at 20-minute intervals.  A brittle, yellow brown resin of m.p. 37 DEG  C. and soluble in xylol, acetone and raw wood oil is obtained.

In the form shown, the arm P is rockingly mounted on a shaft D carrying the rammer E, this shaft being rearwardly moved by the gun during recoil to the position shown in Fig. 6, where the shaft is held by a catch H to cock the loading spring G. The. support P is held rearwardly of the rammer E against the action of a spring Q within a casing d<9> by a catch p<5> engaging a movable stop S on a shaft M slidable with the rammer in a casing b<3>. The rammer E, spring mounted transversely in the rammer head D', is also retained in the retracted position shown by Fig. 5 by a catch K engaged by an arm m<1> on the shaft M. Towards the end of the run-out (Fig. 6), an incline a<5> on the gun engages an arm m<2> on the shaft M and rocks the shaft to release simultaneously the catch K retaining the pusher E and the catch p<5> retaining the support P. The support P then moves towards the rammer, and by means of a cam groove d<11> is rotated from the position shown in Fig. 4, in which it leaves a clear passage for the ejection of the spent case, to the position shown in Fig. 8, where it is ready to support a cartridge with the rammer E behind the base thereof. On operating the handle H<2> to release the catch H, the rammer pushes the cartridge into the gun, the rammer passing through a gap a<2> in the breech whilst the support P is stopped by the rear of the gun to cock the spring Q and cause the cam slot d<11> to rotate the support clear of the breech. The breech is then automatically closed, the wedge breech-block C engaging the rammer E to return it against the catch k. Specification 3790/03 is referred to.

Abstract: 594,501. Indicating-apparatus. ELECTRICAL INSTRUMENT CO. (HILLING- TON), Ltd., and MORRIS, W. July 3, 1945, No. 16950. [Class 106 (iv)] [Also in Group XXXVI] The dial of a measuring instrument is capable of rotary adjustment so that any sector can be brought within the range of movement of the pointer, the tension of the controlling spring being correspondingly adjusted. In the moving coil instrument shown, a rotatable bush supported by a cross-bar i of the movement frame carries on its inner and outer portions respectively a radial arm n and a circular graduated dial m so that anti-clockwise rotation of the latter according to the range of measurement required increases proportionately the tension of a control spring k fixed to the outer end of the arm n. Movement of the dial m in the opposite direction shifts the pointer l from its initial position so that the instrument can then be used as a current direction indicator.
