Abstract: 1,052,431. Laminates and laminating. ENGLISH ELECTRIC CO. Ltd. May 31, 1963 [June 5, 1962], No. 21672/62. Heading B5N. [Also in Division F2] A laminated article made in one continuous length and having a rigid fibre-reinforced resin layer on opposite sides of a core material, is made by feeding two layers of fibre reinforcement through a bath of heat-settable resin to impregnate the reinforcement, and feeding the core material with the layers of impregnated reinforcement on opposite sides thereof continuously through a heated die to cure and harden the resin and to bond the layers to the core material. The reinforcement may be of glass fibre, sisal or other material. In the production of a sheet article, Fig. 1 (not shown), the core material 18 may be a honeycomb of paper, a polyurethane foam material, or a board made from wood or asbestos material. The die has a heated zone 13 between cooled entry and exit zones 12, 14. Tension is applied by a take-off gear 19. In a modification, Fig. 2 (not shown), the core is formed of a material which can be foamed in the die and is fed in through a pipe 20. In the production of an article forming a pipe, Fig. 3 (not shown), the core is formed by a plastics or rubber pipe 21, and the layers 15, 16 of impregnated reinforcement are formed by concave rollers so that together they just surround the pipe. The pipe may be cooled by passing air or water through it.

Abstract: 1,054,815. Fusing metal oxides UO 2 , ZrO 2 , ThO 2 , TiO 2 , CeO 2 . COMMISSARIAT A L' ENERGIE ATOMIQUE. Jan. 23, 1964 [Jan. 31, 1963], No. 3038/64. Heading C1A. [Also in Division B1] Refractory compounds, e.g. UO 2 , ZrO 2 , ThO 2 , TiO 2 , CeO 2  or mixtures thereof, having a fusion temperature at least equal to 1900 C., and at the fusion point a thermal conductivity which is less than 0À05 cal./soc./ C./cm. and an electrical resistivity at most equal to 100 ohmcm.<SP>2</SP>/cm. and preferably between 100 and 0.001 ohm-cm.<SP>2</SP>/cm., are melted by converting the compound into a substantially cylindrical sample, preheating at least part of the sample to a temperature close to the melting-point, and then passing through an induction coil disposed about said sample an HF current the frequency of which is such that the ratio between the radius of the sample and the depth of penetration of the current into the sample is at least equal to 1.5 and preferably between 1.5 and 3 at the fusion point. The result of this activity is that the middle of the sample melts, leaving an outer skin which acts as a "crucible" to protect the molten material from contact with the atmosphere or other impurity. The " crucible " may be tapped by utilizing a secondary heater to form a hole in the shell or skin and running the molten material into a mould, or alternatively the sample can be shaped so that one end forms no enclosing crust and the molten interior can either be pulled out on a seed crystal or run out into a mould. The method can be applied to a rod of the material, when by moving either the rod or the coil a molten zone traverses the rod. If desired, after melting, the molten material may be allowed to solidify in situ when the material which remains solid for the duration of the process is machined away or otherwise removed. As a result of the melting process, refractory compounds having an increased density may be obtained; these materials may then be reduced to a desired particle size.

Abstract: 1,228,558. Piece of jewellery. G. ALBERT. 27 Feb., 1970 [5 March, 1969], No. 9550/70. Heading A3H. A piece of jewellery, such as a finger ring, ear ring and the like, comprises a housing 1 in which a gem 2 or other decorative piece (which may be spherical, cubical &c.) is able to slide. The end 3 of the housing is open to allow the gem to be seen but has a raised portion 5 to prevent the gem from passing through the opening. At the other end there is an aperture 4 through which the gem is inserted or withdrawn. In the case of a finger-ring, the wearer's finger locks the gem in place, but other embodiments have some mechanical locking device such as a spring ring.
