Title: Improvements in or relating to polyurethanes
Inventor: HAMPSON HORACE NEIL
IPC: C08G18/48
Filed: 1960-10-03
Abstract: In a process for the preparation of a polyurethane from an organic polyisocyanate or polyisothiocyanate reactant and a polyether reactant, the polyether reactant comprises a polyol having an average molecular weight of at least 4,000 and formed by reacting (1) a condensation product of an alkylene oxide reactant and an organic compound having at least three active hydrogen atoms in the molecule with (2) at least 1% but less than 10% of ethylene oxide (by weight of the alkylene oxide content of the condensation product). "Alkylene oxide reactant" means any organic compound or compounds, except ethylene oxide, which contains in the molecule an epoxy group capable of reacting with the active hydrogen atoms of an organic compound having a plurality of active hydrogen atoms in the molecule to form a condensation product.  Polyurethane foams can be prepared by the one shot or prepolymer methods.  Prepolymers containing either free isocyanate or hydroxyl radicals can also be converted into polyurethane plastics.  In preparing the polyols there can be used nucleating agents containing active hydrogen as part of hydroxyl, phenolic, carboxylic, mercaptan, thiophenol or thiocarboxylic groups. Examples are glycerol, pentaerythritol and sucrose.  The condensation products reacted with the ethylene oxide can be random or block copolymers obtained from a plurality of alkylene oxides other than ethylene oxide.  In preparing prepolymers up to 0.5% water can be present to give a "water-branched" prepolymer, The reaction can be effected in inert gas atmosphere. The propolymer can be converted to synthetic rubber by heating with inorganic or organic bases or to plastics by reaction with water, glycols, diamines, dicarboxylic acids, hydroxyamines, hydroxy acids or amino acids.  Foams can be prepared by reacting the prepolymers with water, hydrogen sulphide, carboxylic acids, or esters or polyesters containing free carboxylic groups.  A film of a solution of prepolymer in benzene, toluene, xylene, solvent naphtha, gasoline, carbontetrachloride ethyl acetate or amyl acetate can be exposed to atmospheric moisture or reacted with an organic compound containing active hydrogen atoms to give a polyurethane sheet.  In examples the polyols are prepared (1) to (5) by reacting glycerol in the presence of potassium hydroxide with propylene oxide and reacting the product with different amounts of ethylene oxide. They are converted to foams by the one-shot method by reaction with tolylene diisocyanates, water, silicone fluid and mixtures of (1) triethylene diamine, dibutyl tin laurate and stannous octoate, (5) triethylamine, triethylene diamine and dibutyl tin laurate. Specification 868,996 is referred to.

Title: Metal powders
Inventor: WEST DE WITT HENRY
IPC: C22B23/06
Filed: 1964-08-19
Abstract: Carbonyl nickel powder in which the particles are substantially spherical is produced by decomposing the carbonyl in the presence of sufficient 'active' nitrogen to give a powder containing at least 0.01% nitrogen.  The 'active' nitrogen may be produced by the reaction of nitrous oxide and hydrogen but is preferably formed from ammonia and oxygen in the range 0.75-4 parts ammonia to one part of oxygen by volume.  Nitrogen may readily be removed from the powder by heating it to a moderate temperature (e.g. 250 DEG C).  If the reaction is performed in a reactor having nitrided steel inner surfaces the formation of high carbon particles is avoided.  The powder may be in the 'A' form (i.e. discrete spheres) or the 'B' form (i.e. interlocking chains of interconnected spheres).

A fuel assembly for a boiling nuclear reactor comprises an outer container tube 2 of zirconium alloy in which a plurality of fuel rods 20 are arranged in concentric circles, means being provided for causing coolant to flow outwardly radially with respect to the tube 2 past the fuel rods 20. The invention is described with particular reference to a reactor in which heavy water is used as a combined coolant-moderator. The fuel assembly is built up from a number of subassemblies 29 each comprising spaced annular treys 30 with upturned edges, through openings in which trays the fuel rods 20 pass, a grid disc 26 fitted to the bottom of each of the fuel rods 20 and a grid tray 28 with upturned periphery fitted to the top of each of the fuel rods 20, the top grid trays 28 accommodating the bottom grid discs 26 of the adjacent subassemblies 29. The subassemblies 29 are stacked around an inner header tube 14 having perforations 16, water flowing up the tube 14 and radially through the perforations 16 past the fuel rods 20, finally passing up the inside wall of the container tube 2 past radial supports 36 adjacent the grid trays 28 to the upper region of the tube 2 where a spiral deflector 38 of zirconium alloy is situated. This causes rotation of the upcoming steam and water mixture, driving the water outward towards the tube 2 and through a steam separator 44 which comprises an outer sleeve 46 disposed around the top of the tube 2 having an inwardly extending lip 56. Perforated support rings 50, 54 allow the water to pass down between the tube 2 and the sleeve 46 to join the main body of water surrounding the tube 2 while the steam passes up along the axis of the separator 44. The upper portion of each tube 2 (Fig. 3) fits snugly into an upper grid 42 while the lower portion (Fig. 2) accommodates a lower grid fitting 4 of zirconium alloy supported by a lower grid 6. The top 12 of the grid fitting 4 has a recess to house the grid disc 26 of the lower subassembly 29 and a bore to house the header tube 14, this being closed at the top by a disc 18. The fuel rods 20 comprise rods of natural uranium 93.5%, zirconium 5% and niobium 1.5% by wt. encased in sheaths of zirconium alloy. Specification 886,874 is referred to.

Abstract: 980,066. Hospital refuse shoots. MATTHEW HALL & CO. Ltd. Dec. 6, 1963 [Sept. 6, 1962], No. 34239/62. Heading B8S. Hospital refuse is discharged from the ward through door 4, the door being opened either by means of pedal 8 or of handle 9. The refuse lodges in chamber 1. The operator then rotates handle 36 in steps of 90 degrees at a time, the door 4 being closed and maintained closed by engagement of plate 37, and as handle 36 is thus rotated to cause the rotation of shaft 21, three things are thereby effected in time sequence. Firstly, the rotation of cam 34 causes water from tank 28 to be released to flush chamber 1. Secondly, the rotation of cam 20 releases catch 17 to allow bottom door 5 to swing open so that the refuse and water descends down pipe 3 into pipe P and so into a furnace beneath. Thirdly, and lastly, the rotation of cam 27 causes lever 25 to close the bottom door 5 so that the system is now reset for further use. The furnace.-The refuse and water descends down pipe P, the water being discharged at 46 and the refuse being delivered by rollers 43 on to endless belt conveyer 47, which delivers the refuse on to belt 49. As the refuse is being conveyed on belt 49 gas burners 52 (which are brought into operation by photo-cell 55) operate to burn the refuse and the resultant ash is discharged either at 53 or at 40. A photo-cell 59 operates if the refuse is not being burnt to give signals positioned at the doors 4 to warn that further refuse should not be discharged theredown.

To facilitate the removal, from a hole in sheet metal, of a piercing punch which is not fitted with a stripper the punch is constructed so that it expands radially when pressure is applied to the punch head and is free to contract radially during the return stroke. The punch consists of a shank 1, a restraining member 3 which has a bore 5, a punch head 6 which is divided into segments 7 and an extension of the shank which has a conical end 9. The cone 9 co-operates with a similarly shaped surface 8 on the segments 7. Axial movement of the segments on the shank is limited by a flange 10 on the shank which engages a groove 11 in the segments. A removable centre 12 carries a centre-punch 13 which facilitates positioning of the work. Operation.-When pressure is applied to the shank 1 the pressure of the cone 9 on the surface 8 causes the segments to expand a few thousandths of an inch until they abut the wall of the bore 5. When the pressure is released the segments are free to move radially inward as the punch is withdrawn from the work. The construction is stated to be suitable for punches which are 5/8 inch or more in diameter. To sharpen the punch, the centre 12 is removed and replaced by a screw and washer which moves the segments against the cone 9.
