Title: Improvements in devices for making cups and similar vessels of a thermoplastic material
IPC: B29C51/34
Filed: 1963-01-25
Abstract: 1,023,062. Sheet drawing. J. G. H. OLLIER, G. F. GROSSHANS, and R. G. MASSON. Jan. 25, 1963 [Feb. 1, 1962], No. 3225/63. Heading B5A. A hollow cup - shaped article is produced from thermoplastic material in two stages, the first stage resulting in an article with a flat bottom 21, Fig. 3, and the second stage comprising depression of the bottom to the level of the inward projection 11. The jacks 5, Fig. 1, are operated to move the support 3 so that the thermoplastic sheet 1 is clamped between the mould 2 and the box 16. The jack 10 is then operated to lower the plunger 8 and at the same time air is blown through the conduit 18 so that the sheet is applied against the inside wall of the mould 2 causing the article to assume the shape shown in Fig. 3 with the flat bottom 21 and projection 11a. The jack 14 is then operated to move the counter plunger upwardly to the level of the projection 11a. The jacks are then operated in the reverse sequence to allow removal from the mould.

Title: Improvements in or relating to Interference Protection Arrangements for Inverters
IPC: H02M7/516
Filed: 1967-01-23
Abstract: 1,174,116. Inverting; supply systems for gas discharge lamps. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 23 Jan., 1967 [25 Jan., 1966], No. 3284/67. Headings H2F and H2H. [Also in Division H3] An inverter for supplying gas discharge lamps 17, 18 is fed from a D.C. supply through an inductance 4 considerably greater than the input inductance of the inverter, and is shunted by a capacitor 5; if one of the controlled rectifiers 11 and 14 fails to become non-conducting at the proper time due to interference, the capacitor 5 discharges in an oscillatory manner through the inverter and switches off the affected rectifier when it reverses its charge, and means are provided for temporarily inhibiting conduction of the rectifiers. In the arrangement shown in Fig. 1, when the charge on capacitor 5 reverses, the diode 37 conducts and charges a capacitor 31, thereby applying a bias between common terminal B and terminals A and C which supply the triggering pulses to thyristors 11 and 14 and so nullifying the triggering pulses. The latter are produced by an oscillatory circuit 24-26 coupled to the oscillatory circuit of the inverter via inductance 27 and to terminals A-C via a ferrite core pulse transformer 26. An initial start pulse is produced by the start unit 21. Another type of inverter, Fig. 2 (not shown), uses a single thyristor (45) and includes in its input circuit the primary winding of a transformer (46) having its secondary winding connected through a diode (56) and a Zener diode (57) to a capacitor (58) in the triggering pulse supply circuit. If excessive current flows through the transformer, the Zener diode conducts and allows the capacitor (58) to charge and thereby nullify any triggering pulses.

Title: Improvements in or relating to a process for the production of substantially iron free aqueous solution of phosphoric acid
IPC: C01B25/238
Filed: 1965-01-27
Abstract: 1,051,521. Removing iron from aqueous phosphate-containing liquor. ISRAEL MINING INDUSTRIES-INSTITUTE FOR RESEARCH & DEVELOPMENT. Jan. 26, 1965 [Feb. 20, 1964], No. 3320/65. Heading C1A. A substantially iron-free aqueous acidic solution containing phosphate, chloride and sulphate anions, and cations present in phosphate rock, which may be further processed to produce phosphonic acid is produced from an aqueous liquor containing the above ions and also iron, by extracting the liquor with a solvent selected from the group consisting of aliphatic alcohols, ketones, and esters of limited mutual miscibility with water, the total volume of solvent used being less than the volume of said liquor, and separating the iron containing extract from the liquor. The volume of solvent is preferably 1 volume to 5-10 volumes of liquor. Solvents preferred are iso-amyl alcohol, aliphatic alcohols with more than 5 carbon atoms and esters containing from 5 to 18 carbon atoms, particularly amyl acetate, other solvents detailed are di-isobutyl ketone, hexanol, octanol and cyclohexanone. The solvents may be mixed with an organic liquid with dielectric constant from 27 to 45, e.g. nitrobenzene. The starting liquor preferably contains 40-80 grams per litre of hydrochloric acid. The organic extract may be stripped of any coextracted P 2 O 5  by contacting with an aqueous recycle containing ferric chloride and hydrochloric acid and the iron may then be removed from the organic extract by washing with water. Alternatively the organic extract may be treated to reduce any trivalent iron to bivalent iron and the bivalent iron may be removed from the extract by precipitation or by extraction with water.

Title: Laminated articles
Inventor: HULSE GRAHAM
IPC: B29C51/14
Filed: 1956-02-03
Abstract: 822,609. Laminates. MONSANTO CHEMICALS Ltd. Jan. 9, 1957 [Feb. 3, 1956], No. 3463/56. Class 140. Laminated articles are produced by a vacuum-forming process in which two or more superimposed sheets of thermoplastic material are used, each sheet other than the one farthest from the mould being perforated so that air can be withdrawn from between the sheets during the moulding operation. The thermoplastic material may be modified polystyrene, e.g. toughened by natural or synthetic rubber, polyvinyl chloride or cellulose acetate, and the sheets may be of different materials or thicknesses. The perforations may be small and may be made with a needle. They may be in a part of the sheet or sheets which in the finished laminated article can be trimmed off. An interlayer, which does not prevent the sheet farthest from the mould from being drawn on to the mould may be inserted between the sheets before moulding. The interlayer may provide strength or may be ornamental and may be of, e.g., paper, fabric, metal foil, filaments of metal or polymers, glass fibre mats or woven glass cloth. In a preferred form of the invention the interlayer is ornamental, the thermoplastic sheet on one side of it is transparent and that on the other side is opaque, the sheet farthest from the mould may be of P.V.C. or toughened polystyrene and the other or others of transparent cellulose acetate. A bonding agent, e.g. an adhesive, particularly a resin adhesive, or one of several specified solvents for the thermoplastic materials, may be employed to bond the layers together, or the laminµ may be bound together by external means or by pressure at the edges. In a modification, instead of forming the superimposed sheets simultaneously on the mould, a sheet other than that farthest from the mould is separately drawn on to the mould and is perforated after it has been drawn, and another sheet is subsequently drawn on to the perforated sheet. If necessary this sheet may then be perforated and other sheets added to the laminate in the same way. Interlayer material can be inserted between the moulded sheets either before the second sheet is drawn, or if the sheets are not bonded together, after the forming is completed.
