Title: Method and mould for making ornamental plastics articles
IPC: B44C3/04
Filed: 1976-08-11
Abstract: 1518379 Moulding decorative articles B WALTERS 11 Aug 1976 33413/76 Heading B5A A decorative plastics article is made by filling the pockets of a first mould form 28 with particulate plastics material 52, the pockets being defined by a base 30, a peripheral wall 32 having the outline of the article, and internal walls 34. A powdered plastics material is applied to a second mould form 40, having a pheripheral wall shaped to telescope over the peripheral wall 44 of the first mould form, and is heated to form a tacky layer 56. The second mould form is then applied over the first (Fig. 11D) and the assembly thus formed is inverted to cause a layer 56 of the particles 52 to adhere to the tacky layer. The assembly is re-inverted, the mould form 40 removed, the composite layer retained by the form 40 heated to cause the component layers to bond but not sufficient to cause the particles of layer 56 to coalesce completely, and the resultant decorative article removed from the form when it has cooled. A variety of easily reproducible decorative effects are attained by using different coloured particles in different pockets of the first mould form. If desired a third form 40 having inked walls 50 may be pressed on to the composite layer on the second form to enhance the decorative effect, the pressure being hard enough to emboss the surface if desired. The heating of the powder in the second mould form may be effected by an oven 58, a liquid bath, or by a radiant heater or alternatively by the residual heat if the form is preheated. The walls 50 of the third form 40 may be inked by passage under a roller 60, 62. The powder may be applied electrostatically to the second mould form.

Abstract: 1,269,101. Lasers. NIPPON SELFOC CO. Ltd. 3 July, 1969 [6 July, 1968; 18 Nov., 1968], No. 33600/69. Heading H1C, [Also in Divisions C1 and C4] A glass or plastics laser active medium has an inherent graded refractive index which decreases outwardly from its longitudinal axis, the grading being in accordance with a quadratic law and produced by a thermal ion substitution process. The active medium may be a glass fibre of about 0�2 mm. diameter formed, in weight per cent, of 20% Tl 2 O, 12% Na 2 O, 15% PbO, 3% Nd 2 O 3 , 2% UO 2  and 48% SiO 2 , the ion substitution being effected by immersing the fibre in a heated bath of potassium nitrate so as to produce a graded substitution of potassium ions for the thallium and sodium ions. An alternative is the use of 5% Nd 2 O 3  in the above composition and the omission of UO 2 . Alternative laser glasses are silicate glass, borate glass or phosphate glass which include activatable ions such as neodymium, ytterbium, erbium, samarium and holmium ions. Other suitable materials are SiO 2 -K 2 O-BaO glass or SiO 2 - K 2 O-PbO glass which is doped with neodymium. In a modification, Fig. 3 (not shown), a glass fibre formed in weight per cent, of 20% Tl 2 O, 12% NaO 2 , 16% PbO, 4% Nd 2 O 3  and 48% SiO 2  is inserted in and fused to a glass tube formed, in weight per cent, of 20% Tl 2 O, 12% Na 2 O, 20% PbO and 48% SiO 2 . In the compound active medium so formed, lasing is restricted to the core portion while the graded refractive index produced by ion substitution extends over the whole medium. It is stated that the graded refractive index restricts the loss of light transmitted through the active medium. A laser is shown in Fig. 4 in which the glass active medium 9 is in the form of a helix surrounding a straight optical pumping source 10. A cylindrical reflector (not shown) is optionally provided. The glass fibre active medium may be optically pumped by a source 15, Fig. 5, and form one or more amplifiers in an optical system comprising a laser oscillator 11, light guide portions 13 and a receiver 14. A single light guide formed of the graded refractive index fibre described may be used with doping by active ions restricted to the zones where amplification by optical pumping is to take place.

Filed: 1936-12-10
Abstract: Phosphorus, sodium, silicon, sulphur or aluminium are obtained from their ores or compounds by the process described in the parent Specification in which the ores &c. are treated with excess of graphitic carbon, preferably in granular form, and heated in a closed still by means of high frequency induction to a temperature above the boiling point of the element to be recovered but below the boiling point of the ore body, the still being maintained at a pressure below atmospheric, e.g. of the order of 0,1 cm. Hg.  The element is distilled off continuously, and condensed and collected in a suitable receiver.  Frequencies of the order of 300,000-500,000 cycles per second are used.  Low grade phosphoric iron ore may be treated at about 600 DEG  C. under a pressure below 180 mm. Hg., e.g. at 50 mm. Hg., using a frequency of 300,000 cycles per second.  Phosphorus and sulphur are distilled off and may be recovered, e.g. by bubbling the gases through water.  The residual mass is then further heated, while maintaining the vacuum, to melt the iron which is tapped off.  The product is free from phosphorus and silicon.  The silicates appear to separate and float on the molten iron.  Other examples describe the production of aluminium from bauxite at a pressure of 20 mm. Hg. and the production of silicon from quartz at a pressure of 76 mm. Hg.  A frequency of 380,000 cycles is used in both cases.  The aluminium vapour may be shock-cooled, e.g. on to cooled glass to give a mirror-like surface.ALSO:Sodium or aluminium are obtained from their ores or compounds by the process described in the parent Specification in which the ores &c. are treated with excess of graphitic carbon, preferably granular formed, and heated in a closed still by means of high-frequency induction to a temperature above the boiling point of the element to be recovered but below the boiling point of the ore body, the still being maintained at a pressure below atmospheric, e.g. of the order of 0,1 cm.
