Abstract: 1,173,501. Moulding hollow articles. UNIROYAL Inc. 24 Jan., 1967 [24 Jan., 1966], No. 3633/67. Heading B5A. [Also in Division B7] To render a hollow spherical body (25), Fig. 1 (not shown), capable of withstanding high external pressure, the wall thereof is constituted by a plurality of pieces of a synthetic resin e.g. an epoxy, phenolic, melamine or maleic alkyd/ styrene copolymer polyester resin, reinforced with radially-orientated fibres made of e.g. glass, asbestos, boron, carbon, sapphire or tungsten, spaces between said pieces being filled with a cured resin e.g. an epoxy resin. The body may be used as an underwater-exploration vessel. In a method of making the body aforesaid, a plurality of sheets 27, Fig. 6a, of said fibrereinforced resin are cut to a suitable shape before a sheet 28 of backing material having an adhesive substance on both sides thereof is attached thereto, the resin being subsequently cut into a multiplicity of square or rectangular pieces 27a, Fig. 5, without severing the backing material. The sheets of resin are then assembled upon a hemispherical form or mandrel 29 with the sheets 28 adjacent thereto, the spaces between the said pieces being filled with resin in vacuo when the assembly is complete. After curing the resin, the mandrel 29 is removed and the backing material is stripped off the interior of the resultant hemispherical body, two of such bodies being attached to each other by e.g. an epoxy resin, to form the spherical body. The mandrel 29 may be made of an alloy having a low melting-point e.g. Wood's metal, so that it can be removed from the interior of the hemispherical body by rendering it molten. The sheets of resin can be cut to any shape convenient to assembly thereof. As shown in Fig. 5, the shape may be such as to be half that of a lune of the sphere when the sheet is applied to the mandrel. Alternatively, the shape is such that each sheet constitutes one twelfth part of the wall of the hemispherical body, Figs. 8 to 10 (not shown). As another alternative, the sheets merely have rectangular shapes, Figs. 11 to 15 (not shown). As a further alternative, the sheets are cut and assembled in the manner of barrel-staves with a cement therebetween to form a part-cylindrical body 44, Fig. 18, which is subsequently cut along the phantom lines 46, 46a to provide a plurality of curvilinear strips, the latter being thereafter put together with epoxy resin therebetween to form the spherical body, Figs. 20 and 20a (not shown).

Abstract: 1494122 Oscillator circuits; magnetic field generators PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 29 Jan 1975 [1 Feb 1974] 3903/75 Heading H3B [Also in Division H2] A circuit for generating a series of cycles in a coil L 20 , particularly a magnetic bubble drive field coil, comprises a potential source POW 1 connected in series with a controlled current source T23, a rectifier D23 and a parallel resonant circuit consisting of the coil L 20  and a capacitor C 20 , a further rectifier D22 and resistor R20 connected across D23 and L10 to critically damp oscillations at the end of the halfcycle following termination of oscillation by the control circuit CTR 1. In the quiescent state, T 23  is turned on by T 22  establishing a high impedance current mirror source maintaining bubbles in a stable position relative to an overlay. When control unit CRT 1 cuts off T 22  and thereby T 23  the circuit performs a half cycle during which D 23  is forward but D 22  reverse biased owing to the transfer of charge to capacitor C 20 . At the beginning of the second half, D 23  reverses and T 23  may again be turned on and its current superimposed on the oscillation to introduce R 20  as the critical damping resistor. The circuit can perform another cycle after a half-period rest. A modification (Fig. 4) includes extra switching transistors and diodes paralleled with those of Fig. 3 to allow choice of current and therefore rotating field directions. A further modification (Fig. 5) has the diode D23 connected between the capacitor and coil and antiparallel to another switching transistor (T 24 ) which is actuated during the first halfcycle.
