Abstract: 1446914 Blow-moulding; orientation MONSANTO CO 24 Aug 1973 40244/73 Heading B5A A biaxially oriented thermoplastic container is formed by extruding a tubular parison, closing a first mould thereon to thereby pinching its lower end, blowing the parison against the cooled surfaces of the mould cavity to form a pre-form having a cooled surface, transferring the pre-form to a zone where the entire wall thickness is reduced in temperature and stretching it longitudinally to orient it and finally blowmoulding the pre-form in a cooled blow-mould. A parison (12, Fig. 1, not shown) is extruded from extrusion head (14) having an axially movable mandrel (16), movement of which may be programmed to produce a varying wall thickness as at 81, Fig. 2. The parison is then enclosed in halves 34, 36, Fig. 2, of a first blowmould 32, and pinched shut by portions 118, 120 thereof. The parison is blow-moulded in cavity 38 by air from a needle 50 mounted on a piston 52 moved when air is supplied through duct 54, into pre-form 80 having neck threads 39 and shoulder 41. Mould 32 is cooled at 43. The pre-form is then gripped about its upper flash portion (51, Fig. 3, not shown) by means (74) and transferred automatically or manually to temperature conditioning means (56) having a housing (58) with inlet (60) and outlet (62) for conditioning air and holders (64) for the preforms on a rotary carrier plate (66). The cooled pre-form is then transferred to a final blowmould 82, Fig. 4, having halves 86, 88, cooling ducts 92, and a shaft 96 having a central duct 100 for blowing air. The pre-form 80 is stretched longitudinally by foot 98 of shaft 96 and blowmoulded against cavity 84. The mould is sealed by resilient member 102 mounted on retaining ring 104 and compressively seated on the upper surface 106 of the mould. The material is preferably a polymer comprising at least 60% by wt. of polymerized nitrile monomer, e.g. acrylonitrile or methacrylonitrile, the remainder including at least one polymerized ethylenically unsaturated monomer, e.g. styrene. Many other comonomers may be used. Many impact-modifying resins may be incorporated.

Title: Process for recovering potassium from brines
Inventor: DUNSETH MARIA GARCIA
IPC: C01D7/02
Filed: 1962-10-25
Abstract: Potassium values are recovered as potassium magnesium phosphate from potassium containing brines, especially sea water, by adding magnesium ions (if necessary) and a source of orthophosphate ions such that the molar ratio of orthophosphate ions to magnesium and calcium ions together is at least 0.8, and then raising the pH of the solution to above 7.5 to precipitate potassium magnesium phosphate. A base which may be inorganic or organic is used to raise the pH but the base must not yield a phosphate salt which is less soluble than potassium magnesium phosphate.  The precipitates obtained may be separated and treated with an aqueous solution of an ammonium salt which yields a precipitate of magnesium ammonium phosphates and a solution of potassium salt. Phosphate ions may be provided as orthophosphoric acid or tri-, di-, or mono-sodium salt of said acid. Bases used are the oxides, hydroxides and carbonates of sodium and potassium; organic bases are generally amines.  Ammonium salts specified are chloride, bromide, iodide, fluoride, carbonate, bicarbonate, cyanide, ferrocyanide, ferricyanide, bifluoride, nitrate, nitrite, phosphate, sulphate, sulphite or sulphide.

Abstract: 1,190,285. Mounting rectifiers in dynamo-electric machines. WESTINGHOUSE ELECTRIC CORP. 26 Aug., 1968 [11 Sept., 1967], No. 40636/68. Heading H2A. [Also in Division H1] A diode is held in pressure contact between two heat sink plates which also serve as electrical contacts, at least one of the plates being resilient; a heat resistant insulating spacer is disposed between the plates and about the diode to physically support and electrically insulate the plates. Twelve diodes may be arranged in series-connected pairs as a bridge rectifier for feeding excitation current from a 3-phase alternator to the rotating armature winding of a 3-phase main alternator. The two alternators are on a common or linked shaft 15 (which also carries a pilot exciter) bearing the two rectifier wheels 25, 25<1> of the bridge. Current from one of the exciter phases 31 is fed to a rigid conductor 34 linked by a conductor 51 to one of the six diode pairs 40 and by a conductor 53 to the corresponding diode pair 40<1> on the other wheel. As shown, each diode 20 is clamped between a rigid heat sink plate 46 and a resilient plate 44, the spacers 47 and plates 44 being chosen such that the pressure applied to the diodes with the wheel stationary is sufficient to allow the bridge to be tested and such that the pressure obtained during normal rotation is the optimum value. Diode pairs are interconnected with those on the same wheel via its rim 28. In a variant, both heat sink plates in contact with each diode may be made resilient. In another embodiment (Fig. 4, not shown) each of the solid heat sink plates is replaced by a plurality of plates. Here, the rigid heat sinks are formed of plates separated by peripheral and central conductive spacers, and the resilient sinks are formed of nesting dished plates in mutual contact at their centres and separated by peripheral conductive spacers.
