Title: Improvements in or relating to phosphorescent materials
IPC: C09K11/06
Filed: 1962-02-01
Abstract: A water-resistant organic phosphorescent composition is made by incorporating an organic phosphor in cyanuric acid, an ester or salt thereof, or in melamine; all in the unpolymerized state. Examples of phosphors are 2 - naphthylamine - 7 - sulphoric acid; 2 - naphthylaminoacetyl - 7 - sulphonic acid; paraaminobenzoic acid; para-hydroxybenzoic acid; phthalic acid anhydride; terephthalic acid; naphthalene - 2 - carboxylic acid; 2 - naphthylamine - 6,8 - disulphonic acid; 2 - naphthol - 6,8 - disulphonic acid; fluorene; anthracene; ortho-phenylphenol. Esters of cyanuric acid used may be those of phenol, naphthol, benzylalcohol, low aliphatic alcohols such as methanol or ethanol, methylammonium or trimethylbenzylammonium. The cyanuric acid is preferably formed in the presence of the phosphor, e.g. by cyclization of urea or hydrolysis of cyanuric acid chloride. The proportion of phosphor may be 0.1 to 15%, preferably 0.5 to 8%. The composition may be incorporated into papers, plastic materials, lacquers, impregnating compositions, typewriter ribbons, printing inks, paints, pencils or chalks; a particular application is to coding of record cards and other articles. Fourteen detailed examples are given.

Reversible locks and latches.-The fore-end plate of a reversible rim lock is slidably mounted on a fixed end plate and protrudes at one side of the casing for attaching to the edge of the door. The casing A has a fixed fore-end plate a attached by the tongues a', d' on the casing A and cover-plate respectively. In the form shown, the tongues a', d<1> space the fixed plate a from the end of the casing so that a plate D can slide between the casing-end and the fixed plate a. The plate D may be moved by hand to protrude at the back or front of the casing A, as shown in Fig. 1, so that screws may be inserted through the corner holes into the edge of the door to help to secure the lock. Holes d allow the lock- and latch-bolts to pass through the plate D in either of its positions, and also from guide-slots for the plate when it is slid into position. The tongue a<1>, d' act as stops to limit the motion of the plate. In a modification, the plate D may be arranged to slide over the outer face cf the fixed plate a. The latch bolt C has an inner yoked part c carrying the tail c<1> of the latch head. To reverse the latch it is pulled outwards against its spring c' to bring the circular part c<4> into the rectangular hole in the end plate turned through 180‹, and released.

Title: Improvements in or relating to magnetic data-stores
Inventor: BARNET PETER ALAN
IPC: G11C11/06
Filed: 1962-02-01
Abstract: In a magnetic storage matrix comprising a woven assembly of magnetic strips or threads and insulated electrical conductors (see Division H3), the strips or threads are formed from nylon which is coated with a thin film of ferro-magnetic material after the assembly is woven. The nylon strips or threads are sensitized by immersion in a solution of stannous chloride, followed by washing, and immersion in a solution of acidified palladium chloride.  The ferro-magnetic film is then deposited on the threads by immersing them in a solution of nickel chloride, cobalt chloride, sodium hypophosphite and sodium bitrate in the respective proportions of 51, 34, 100 and 125 grammes per litre, the temperature being 85  DEG C. and the pH value 11.2. The pH value is obtained by using concentrated ammonia.  The resulting thin film has a thickness in the order of 3000 Angstrom units and contains 45% nickel, 45% cobalt and 10% phosphorus.  The pattern of the coating may be controlled by the use of a resist which is printed or sprayed on the woven structure. The magnetic coating can be endowed with a preferred axis of magnetization by applying currents to the matrix conductors during the deposition process. To obtain the required value of coercivity the film may be heat treated for 2-3 minutes at a temperature of 150  DEG C. Specification 972,846 is referred to.

Title: Improvements in or relating to the production and separation of sulphonated organic compounds
IPC: C07C309/28
Filed: 1949-02-19
Abstract: The sulphonic acid obtained by reacting an aromatic compound with oleum or sulphur trioxide in the presence of liquid sulphur dioxide as a solvent is recovered by a process which comprises adding to the solution before or during distillation an inert volatile organic compound which is mobile at -10 DEG  C. and distilling off all the sulphur dioxide and some of the organic compound.  In one form of the invention the organic compound is added to the liquid feed to the distillation zone.  Compounds mentioned for this purpose include paraffins of at least 4 and preferably 4-8 carbon atoms, naphthenes of 5-8 carbon atoms such as methyl cyclohexane and aromatic hydrocarbons such as toluene, aliphatic ethers having not more than 4 carbon atoms such as methyl, ethyl, and methyl-propyl ethers, cyclic ethers such as furan and low molecular weight halogenated hydrocarbons such as chloroform, ethylene dichloride, carbon tetrachloride and methylene dichloride.  It is preferable that the organic compound should form a minimum constant boiling mixture with sulphur dioxide at atmospheric or lower pressures.  This procedure may be carried out batchwise in which case the solution of sulphonic acid in liquid sulphur dioxide is diluted with 2-3 times its volume of organic compound and distilled in a pot still below 0 DEG  C.  In continuous operations the solution of sulphonic acid in sulphur dioxide is fed to a column in which the organic compound is being refluxed.  The overhead product is settled and the liquid sulphur dioxide lower layer removed.  The organic compound for this method of carrying out the invention should be of low solubility in sulphur dioxide.  Compounds mentioned include paraffins of 3-7 carbon atoms and ethers such as methyl ethyl ether and diethyl ether.  An apparatus for carrying out the invention is shown in diagram form, and two examples are given.  Specification 680,613 is referred to.
