Title: Reducing troublesome effects of salts deposits in the tube systems of steam generators
IPC: B01J39/00
Filed: 1955-11-07
Abstract: A method of reducing troublesome effects of salts deposits in the tube system of a steam generator which normally operates at or above the critical point of the working medium comprises first preparing the water by a so-called total salts elimination treatment and thereafter, by means of an additional ion-exchange, replacing, predominantly by potassium ions, the metal ions of the traces of salts still present in the prepared feed water.  In one example the so-called total salts elimination treatment is effected by passing the water through a cation exchanger and an anion exchanger in series.  The additional ion-exchange is then provided by a cation exchanger which has been regenerated by a potassium compound, preferably the chloride or sulphate. Alternatively the water may be purified by precipitation softening followed by vaporisation, the resulting steam being passed through a condenser and the resulting condensate being passed through a potassium cation-exchanger before being fed to the generator.  In a closed circuit, water from a feed water tank is pumped to a steam generator whence steam passes to a turbine and thence through a condenser, the condensate being returned to the feed water tank: in this instance a potassium cation-exchanger is interposed between the condenser and the feed water tank.

Patent GB-1480617-A (GB)
Title: Data stores
IPC: G11C17/00
Filed: 1974-07-18
Abstract: 1480617 Data storage systems SPERRY RAND CORP 18 July 1974 [19 July 1973] 31860/74 Heading G4C [Also in Division H3] The system includes a matrix of variable threshold insulated-gate field-effect transistors and means for selecting a word row of the matrix. The word in the selected row is gated to a register. Further gates control the readout or write-in to the register. The gates and transistors are controlled by a source of a cyclic sequence of voltages such that the following 4-step cycle occurs: (a) a word is gated from the selected row to the register (b) the transistors in the selected row are set to their maximum threshold (c) the transistors in the selected row are set to their minimum threshold (d) the word in the register is read in to the selected row. Step (b) ensures that the selected transistors are not subjected to an accumulation of positive Write pulses which could set them to a positive threshold, whereby they could be turned on without having been addressed. The source of the sequence of voltages is shown at 25, Fig. 2. To select a row of transistors in the matrix 11 (of which only one transistor of two rows is shown) a multibit address is applied to unit 13 which applies it in true and complement form to a decoder 15 comprising an assembly of NOR gates. During step (a) the voltages are such that a low positive voltage is applied to the output line (e.g. 47) corresponding to the address, and such that buffer 17 places a high voltage, about half the Write voltage, on the corresponding row line 63. When load voltage L becomes high a bi-stable 69 in each stage of the register assumes the state of the corresponding transistor in the selected row. For example, if transistor 31 is on, i.e. if the threshold of transistor 31 is low, node line 93 assumes a low voltage and node line 79 a high voltage. During step (b) the voltage C3 applied to buffer 17 is substantially higher than in step (a) so that the maximum negative voltage is applied to all the transistors in the selected row. During step (c) the voltages change so that a low voltage is applied to the selected row line 63 to change the threshold levels of the transistors in that row to their minimum threshold. The array is isolated from the register during steps (b) and (c) since L and P are low. During step (d) the selected row line changes to the Write voltage, and a transistor in that row is switched to its maximum threshold if node line 93 in bi-stable 69 is high, i.e. the data in the register is written in to the matrix. Data can be passed to and from a stage of the register via an I/O buffer when a transistor (e.g. 81) associated with the stage is rendered conductive by a bit-line decoder fed with a multi-bit address word (Fig. 3, not shown).

Title: Process for lining metallic tubes with thermoplastic material
Inventor: LENO JOHN ALBERT
IPC: H01P3/13
Filed: 1955-11-08
Abstract: 778,034. Lining metallic tubes. STANDARD TELEPHONES & CABLES, Ltd. Nov. 8, 1955, No. 31897/55. Class 99(2) A process for lining a metallic tube with thermoplastic material comprises the steps of inserting the thermoplastic material in the form of a tube within the metallic tube, forcing the plastic material against the internal surface of the metallic tube by a gaseous medium under pressure within the plastic tube, externally heating the metallic tube and plastic tube assembly with the plastic material forced against the internal surface and cooling the assembly. Such tubes can be used as high frequency electric wave guides. As an example the application of a thin tube of polyethylene 1 to the inner surface of a copper tube 2 is described. The internal surface of the copper tube is treated for example either by vapour degreasing in trichloroethylene followed by acid pickling and a thorough washing in water or by the electrodeposition of a flash coating of cadmium or by the formation of a controlled oxide film. The tube is then dried for 2-3 hours at 110-115‹C. with the inside at a reduced pressure of less than 1 mm. of mercury. The inside of the polyethylene tube and the space between this tube and the copper tube are evacuated to less than 1 mm. of mercury. A dry compressed gas such as nitrogen or air is then applied to the inside of the polyethylene tube. For a polyethylene tube with a wall thickness of 0.0127 cms. the pressure is gradually increased to 0.3515 kgms/sq. cm. The vacuum pump is then disconnected from the tube 11 which is closed by a plug having one end flush with the internal surface of the copper tube. The pressure is then increased to 1.406 kgms./ sq. cm. The heating process is then carried out in a thermostatically controlled air circulating oven and. the pressure of the nitrogen is maintained throughout the heating and cooling. The assembly is placed in a cold oven and the temperature slowly increased to about 130‹C. after 1¢ hours. This temperature is maintained for approximately ¢ hr., after which time the heat is switched off and the assembly allowed to cool. The initial dia. of the polyethylene tube is 5 to 15 per cent less than the internal dia. of the copper tube and the wall thickness of the polyethylene tube is substantially within the range 0.00254 cms. to 0.0254 cms.

Abstract: 1,105,185. Recovery of monomers from polymers. MONSANTO CO. 27 July, 1965 [24 Aug., 1964], No. 32048/65. Heading BIB. Unreacted monomers are recovered from a polymer slurry formed by the polymerization of acrolonitrile and another mono-vinyl monomer, by subjecting the slurry to continuous countercurrent steam distillation in a column 20 to vapourize the monomers, condensing the vapours withdrawn and separating the monomers from the condensed water which is fed back to the column as reflux, and separating by filtration the polymer from the remainder of the slurry withdrawn from the base of the column. The slurry may be produced by the emulsion polymerization of acrylonitrile and vinyl acetate in a reactor with the addition of potassium persulphate catalyst, a sulphur dioxide activator and sodium bicarbnate. After the desired dwell period in the reactor, the slurry leaves through a V-shaped line 18 into which oxalic acid is fed to prevent further polymerization and steam to preheat the slurry and to prevent plugging. Monomer separated from the condensed water in the decanter is recycled back to the fresh monomer being introduced into the reactor. The steam feed rate to the column 17 is such as to maintain a vapour head temperature of approximately 90C.
