Abstract: 1,231,437. Steam generators; heat exchangers. FOSTER WHEELER Ltd. 10 July, 1968, No. 32980/68. Headings F4A and F4S. The inlet channel 18 for high temperature gases, e.g. process gases from an NH 3 , H 2 C:CH 2 , CH 3 OH or H 2  producing plant, supplying a shell and tube heat exchanger 20 is provided with a helical gas cooling coil 52. The inlet tube plate 54 from which the heat exchanger tubes 22 extend has a refractory coating 70. The adjacent coils of the coil 52 are welded together and with the metal end seals 66 and 68 form a stagnation region between the coil and the channel wall 62 providing insulation. Water from a steam and water drum 28 is pumped to a flue gas heated economizer 24 and the coil 52 for return to the drum and water flows by natural circulation into the heat exchanger 20 for conversion to steam which flows to the drum. The outlet from the coil 52 may be connected directly to the exchanger 20. Water may be fed to the coil 52 in a once-through loop.

Abstract: 1,238,944. Electro-machining apparatus. MITSUBISHI DENKI K.K. Sept. 18, 1968 [Sept. 18, 1967], No.44436/68. Heading C7B. [Also in Division G3] A workpiece e.g. a turbine blade is electromachined with apparatus in which the flow-rate Q of electrolyte 106 supplied to the working gap between the workpiece 101 and working electrode 102, e.g. by pump 107 from reservoir 105 through conduits 108 and 109, is measured e.g. by electromagnetic flow-meter 110 and compared at 126 with a predetermined constant value Q o , e.g. from reference signal generator circuit 123, to produce an error signal # which controls two of the machining parameters determining the working gap, such as the operating voltage and current and means for feeding the workpiece towards the electrode, until the electrolyte flow-rate Q equals its predetermined constant value Q o  thus maintaining the working gap constant. As shown, the amplified error signal fires the circuit 128 to supply a gating signal to each of the anti-parallel thyristors 122a, b in control circuit 122 fed by a single phase A.C. source 121 which energizes a single phase rectifier bridge 119 connected to a control winding 118 inductively coupled to all the reactor windings 113a, b, c of a saturable reactor 113, connecting a three phase A.C. source 112 to a power transformer 114 in turn connected through a three phase rectifier assembly 117 to supply electrical energy across the working gap. The difference between a machining voltage applied across the working gap (and dependent upon variations of the error signal #) and a reference voltage V o  provided by a potentiometer 142 in a generator circuit 140 excites a valve operating winding 143 which actuates the changeover valve 136 of a hydraulic servo-feed system 130 which includes a hydraulic cylinder 131 and piston 132 for moving the workpiece toward and away from the electrode. Alternatively, a mechanism for feeding the workpiece toward the electrode at a constant feed-rate may comprise a rack and pinion Fig. 10 (not shown).

Abstract: 1,257,910. Laminating method and apparatus. KOPPERS CO. Inc. 15 Sept., 1970 [21 Oct., 1969], No. 44091/70. Heading B5N. A method of producing a laminate comprises applying a lamina of heat curable polyester material to a surface of a substrate, e.g. plywood, in which substrate there are present plugs of a heat-curable polyester material and applying heat and pressure to the resultant assembly. An apparatus for effecting the method comprises in combination a drilling machine 15 to drill holes in a substrate, a plug-inserter device 21 to insert heat-curable polyester material in the holes, means, e.g. rollers 63 to apply a lamina of heat-curable polyester material to a surface of the substrate and means, e.g. heated press 43 to apply heat and pressure to the lamina and substrate to bond them together. In a preferred embodiment, a lamina 53 is bonded to each surface of a plywood substrate 11. The heat-curable polyester material is preferably a composition of an ethylenically unsaturated cross-linking agent, e.g. styrene or vinyl toluene, a thickening agent, e.g. a mixture of calcium oxide with calcium hydroxide or magnesium hydroxide and a polyester derived from an ethylenically unsaturated dicarboxylic acid, e.g. fumaric or maleic acid, and a diol, e.g. ethylene, propylene, diethylene or polypropylene glycol, 1,2-, 1,3- or 1,4- butanediol, 2,2-dimethyl-1,3-propanediol, 1,4- cyclohexane dimethanol or adducts or reaction products of allylene oxides with bis-phenol A.

[Also in Division C3] Flame retardant hard polyurethane foams are made by coating the partially or completely hardened foam (e.g. by spreading, brushing electrostatic or air spraying or trowelling) with a solution or suspension of an ammonium polyphosphate of formula H( n-m ) +2  (NH 4 ) m  P n  O 3n+1 , wherein the ratio m:n is 0.7 to 1.1 in a solution of PVC in a solvent such as methylethylketone, cyclohexanone, tetrahydrofuran, dioxane or dimethylformamide and then drying the coating to a thickness of at least 0.05 mm. The foam may be roughened by emery disc or sand blasting before application of the coating. Preferably, at least 0.1 parts of ammonium polyphosphate per part of PVC is dissolved or suspended in the PVC solution, although this may be partly replaced by up to 30% wt of asbestos wool, ammonium bromide, red phosphorus or other flame retardants.

Abstract: 1,266,792. Sodium cyanide. E.I. DU PONT DE NEMOURS & CO. 4 June, 1969 [5 June, 1968; 28 April, 1969], No. 28229/69. Heading C1A. Granules of agglomerated sodium cyanide crystals are produced by a process comprising the steps of (1) compacting NaCN crystals having a moisture content of not more than 0À05% by weight under a pressure of 5000- 15,000 p.s.i. and at 125-225‹ C. into a translucent non-crystalline sheet or ribbon of sodium cyanide; (2) breaking the sheet or ribbon into granules having a maximum size of USS No. 4 and having no more than 10À25% by weight of the granules finer than USS No. 50; and (3) classifying the granules so that the granular product has no more than 20% by weight of USS No. 50 fines. The NaCN granules may then be compacted into articles e.g. briquets, comprising granules of agglomerated NaCN crystals in which the surfaces between granules exhibit bonds essentially as strong as the cleavage strength of a NaCN crystal. The briquets are formed at 125-200‹ C. and at a pressure of 333-3000 atm. The produced articles have a uniform D Shore hardness of at least 65 throughout and an external compacted portion of higher hardness, the article having a relative density of at least 0À97 and a solution rate equivalent of 8-11 minutes standard solution time. Step (2) is advantageously carried out by breaking the sheet or ribbon into irregular chips of 2À5-5À1 cms. in size which are then granulated. The fines remaining from the classifying step may be recycled to the compacting step (1). The process is also applicable to potassium cyanide.

As exemplified decarburization was effected in wet H 2  by annealing for 3 minutes at 800 C., or by open coil annealing for 5 hours at 750 C. The final anneal (at 870-1200 C.) should be in H 2  to remove Se, Te, and S. Other elements which may be present in the steel include B, Zr, Ti, Nb, Ta, Cr (preferably not more than 0À1% each), W (preferably not more than 0À5%), and V, Mn, Mo (preferably not more than 1% each).
