Title: Polymerization of stryrene
IPC: C08F32/00
Filed: 1957-02-23
Abstract: Isotactic polymers of styrene are made by adding styrene to a catalyst made by adding an organo-metallic compound of a metal of Group II or Group III of the Periodic Table to a halide of a metal of Group IV(a), V(a), or VI(a), in which the halide has its maximum valency either during the formation of the catalyst or to the preformed catalyst. The organometallic and the styrene in solution in an organic solvent may be added dropwise to a solution of the halide in an organic solvent. The halide is preferably titanium tetrachloride and the organometallic compound triethyl aluminium. The polymerization may be effected in the presence of an organic solvent such as benzene or tetrahydronaphthalene. The reaction may be terminated by the addition of methyl alcohol and. he non-isotatic polymer extracted with acetone.

Title: Process for the production of alkenylpyridines and catalyst therefor
IPC: C07D213/127
Filed: 1959-10-13
Abstract: A catalyst comprising zinc oxide together with iron oxide, chromium oxide, and one or more of the compounds:- aluminium oxide, alkaline-earth metal oxides, and alkali metal oxides, hydroxides, and salts, is employed in the production of alkenyl pyridines from alkyl pyridines (see Group IV(b)). Preferably the catalyst contains a major proportion of zinc oxide. It may be composed of ZnO (40-90%), Fe2O3 (5-45%), CaO (1-20%), Al2O3 (1-15%), alkali metal oxide (0,5-10%), and Cr2O3 (0,2-5%). The catalyst may be prepared by mixing zinc and calcium oxides with hydroxides of aluminium, chromium, and iron, which have been coprecipitated from solutions of their sulphates by means of ammonia, adding concentrated caustic potash solution, and submitting the product to oven-drying until a consistency suitable for extrusion is obtained the mass is extruded into rods which are then cut into small cylinders and dried at 700 DEG -750 DEG C. in a stream of nitrogen.ALSO:Alkenyl-pyridines are obtained by subjecting a heated vaporized mixture of an alkylpyridine and an inert gas or steam to dehydrogenation in the presence of a catalyst based on zinc oxide together with iron oxide, chromium oxide, and one or more of the following compounds:-aluminium oxide, alkaline-earth metal oxides, and oxides, hydroxides, and salts of alkali metals. Dehydrogenation may take place at 500 DEG -800 DEG C. The alkyl-pyridine may be 2-ethyl-, 3-ethyl-, 4-ethyl-, 2-methyl-5-ethyl-, 4-methyl-5-ethyl-, 2,4-diethyl-, 2,5-diethyl-, or 2-methyl-5-propylpyridine, or it may be a butyl-pyridine. The preferred catalyst preparations are those containing a major proportion of zinc oxide. In an example, a mixture of superheated steam and vaporized 2-methyl-5-ethyl pyridine is introduced into a reactor tube and passed over a catalyst containing ZnO (80%), Fe2O3 (18%), K2O (1.2%), and Cr2O3 (0.8%) the dehydrogenation temperature is 580 DEG C. in a first test and 600 DEG C. in a second test. The effluent vapours are condensed and methyl-vinyl-pyridine is recovered from the condensate. Pyridine, picolines, 3-ethyl pyridine, and 2,5-dimethyl pyridine are obtained as byproducts. Other examples describe the use of catalysts containing calcium oxide together with the oxides of zinc, iron, chromium, and potassium, and the dehydrogenation of 4-ethyl-pyridine, and 4-methyl-5-ethyl pyridine.

Title: Tubular and porous fibres
IPC: D01F1/08
Filed: 1969-10-29
Abstract: A tubular fibre containing a continuous hollow channel disposed co-axially or parallel to the axis and having a "skin", in which any pores are less that 500 in diameter, over its external and/or internal surface, and having in contact with the skin or skins a network of mutually intercommunicating pores of 500 to 30,000 diameter and being substantially and preferably entirely free of vacuoles (non- communicating voids), the said network being at least a quarter the thickness of the fibre, the remainder of the fibre if any being different from the vacuole-free network may be made by (a) extruding a fibre-forming polymer solution from an annular orifice spinneret, (b) gelling the external and/or internal peripheral zone and (c) simultaneously or subsequently subjecting one or both of the surfaces whether gelled or non-gelled to the action of a coagulating agent. In the examples the "skin" was from 0.5Á to 100Á thick. The fibre may be a polymer of acrylonitrile (AN), AN/methyl methacrylate (MMA) or particularly AN/ MMA/ potassium p-vinyl oxy benzene sulphonate or a polyurethane or polyvinyl chloride. The tubular fibres according to the invention may be used in reverse osmosis, in separation of gases and in ultra filtration. Thus in the examples nitrogen is transmitted through the fibre wall at internal pressures in excess of 1.5 to 2.5 bars and, a water pressure of 2.0 bars gives a flow rate through the fibre walls of 6 to 55cc/hour/metre of fibre.

Patent ES-426347-A1 (ES)
Title: Random access memory system and cell
IPC: H03K5/02
Filed: 1974-05-16
Abstract: In an array of memory cells having the cells in each column coupled together by one of a plurality of address buses, the ground reference potential for each cell is provided by coupling a storage capacitor in each cell to an adjacent address bus. Since only one address bus is addressed at any selected time, the adjacent address buses remain at ground potential so that coupling of the storage capacitors in each addressed cell to the adjacent, grounded address buses supplies the required reference ground for each addressed cell. Refreshing, or restoring of the charges on the storage capacitor in each memory cell is accomplished by a plurality of sense-refresh amplifiers. Each sense-refresh amplifier can be coupled to a selected cell capacitor in a row of memory cells, and includes a first pair of MOSFET devices cross-coupled in a flip-flop configuration. In one embodiment, single phase clock signals are applied to the first pair of MOSFET's through an ON biased second pair of MOSFET's. The clock signals thus applied synchronize the read, write, and refresh functions of the memory. Alternatively, single phase clock signals can be applied to a third pair of MOSFET's coupled in parallel with the first pair, or a clock pulse can be used to short a pair of circuit nodes during an initial time period to bring a pair of load capacitances to a desired, low initial potential. Data signals are applied to and read-out from only one side of the sense-refresh amplifier, and the sense-refresh amplifier also serves to invert the data stored in memory cells on the opposite side, and to re-invert the data on read out.

Title: Method of refurbishing turbine vanes and the like
IPC: F01D5/00
Filed: 1977-06-03
Abstract: A method for repairing turbine vanes and the like which have become worn or cracked after extended periods of use. The method embraces the steps of applying molten metal containing a predetermined quantity of silicon to the cracks, and overall to the worn or eroded areas of the vane to build up the same beyond its original surface, sintering the vane in a furnace at a temperature of over 2,000 DEG F thereby burning off some of the silicon, allowing the vane to cool, and thereafter placing it in a high pressure furnace and subjecting it simultaneously to heating to a temperature in excess of 2,000 DEG F and a pressure in excess of 15,000 PSI to drive the build-up material into all of the cracks of the vane and simultaneously effect a densification of the material as well as improving the bond to the original eroded surfaces. Thereafter the vane is removed and allowed to cool, and the built-up surface of the vane is ground down so as to restore the dimensions of the piece substantially to those of a new part.
