Title: Pharmaceutical radioactive capsules and method of producing same
IPC: A61K51/02
Filed: 1955-03-08
Abstract: A pharmaceutical radioactive capsule comprises walls of a non-toxic, water soluble thermoplastic material, e.g. gelatine, methyl cellulose, polyvinyl alcohol, having a thin film of a radioactive compound adsorbed on a part or the whole of the internal surface of the walls of the capsule.  The radioactive compound which is absorbable in the gastro-intestinal tract, is introduced into the capsule in the form of a solution in a volatile organic solvent which may contain up to 20 per cent water, e.g. 85 per cent and 95 per cent ethanol, methanol, acetone, dioxane, 50:50 methanol ether, which is allowed to evaporate leaving the radioactive compound as a thin firmly adherent film on the interior surface of the walls.  Specified radioactive compounds are alkali metal iodides having radioactive alkali metals, e.g. sodium, potassium, rubidium, or radioactive iodine atoms, potassium di-hydrogen phosphate having radioactive prosphorus atoms, ferric chloride having radioactive iron atoms, sucrose having radioactive carbon atoms, tritiostreptomycin (in the form of chloride) having radioactive hydrogen atoms, penicillin containing radioactive carbon and sulphur and radioactive calcium, zinc and copper.ALSO:A pharmaceutical radio-active capsule comprises walls of a non-toxic water soluble thermoplastic material, e.g. gelatin, methyl cellulose, polyvinyl alcohol, having a thin film of a radio-active compound adsorbed on a part of the whole of the internal surface of the walls of the capsule.

Title: A process for the production of boron trihalides
Inventor: WOOD ANTHONY ARTHUR ROBINSON
IPC: C01B35/06
Filed: 1957-03-01
Abstract: Boron trihalides, especially BCl3 and BBr3, are produced by passing a halogen over granules of an intimate mixture of boric oxide, boric acid or other oxygenated boron compound which forms boric oxide at or below 350 DEG C., carbon and a carbohydrate binder at a temperature of at least 600 DEG C., preferably 1000-1500 DEG C. in a reactor, e.g. a tube provided with a carbon lining, and collecting the boron trihalide from the exit gases in a cooled receiver.  Boric acid, boric oxide or other oxygenated boron compound and carbon are mixed together with a binder, e.g. starch or sugar, pasted with water, and dried at 140 DEG C.  The dried mixture is granulated into particles of from 0.3 to 0.6 inch diameter.  The granules are heated to 350-500 DEG C., preferably in an inert atmosphere, e.g. N2, A or Co, to clear the binder and thereby produce granules containing boron oxide supported on a carbon framework.  The total proportion of carbon to boron (calc as B2O3) is preferably 1:1.  In a modification ready formed boron nitride may be used in place of part or all of the boron compound/carbon mixture and granulation is such as to produce particles of 0.125 to 0.375 inch diameter. Finished granules from either mixture are placed in a rigid graphite or carbon-lined reaction chamber and are heated in a stream of halogen which may be carried in a current of inert gas free from hydrogen, oxygen or water vapour.  The rate of flow of halogen gas and the length of the heated portion of the chamber are adjusted so that no free halogen appears in the exit gases. To prevent rapid deterioration corrosion of the chamber those parts which come into contact with the halogen are maintained above the boiling point of the halogen.  The boron trihalide is collected in a cooled reservoir and any traces of free halogen removed therefrom by treatment with aluminium followed by distillation.

Cleaning matrices.-Amachine for cleaning type-bar matrices or other articles comprises a laterally movable magazine 46 containing several stacks of matrices &c. which are fed one by one between felt cleaning-pads 12, 14, 16, Fig. 3, by pusher-blocks 8 on an endless chain 6. The blocks 8 are spring-supported and are depressed by a fixed guide 9 so as to engage only one matrix. A spring-pressed stop 66 holds back the overlying matrices. The lower felts are carried by supports 13, Fig. 3, from the frame 1, and the side and top felts 14, 16 are carried by yokes 18, 23 which slide on rods 19 and are pressed down. wards by springs 20. The felts are in two secticns separated by a space 26a, the right-hand section being partially saturated with a cleaning liquid and the left-hand section being dry. Cleaning-liquid is supplied from a reservoir 27 under the control of a valve which is oscillated at intervals by a cam. When stack of matrices is exhausted, a spring latch 57 carried by a weight 56 passes through an aperture in the magazine and is engaged by a reciprocating member 58 by which the magazine is moved laterally to bring the next stack of matrices into position. The cleaned matrices pass down a shoot 67 by which they are inverted so as to fall on their feet, and are pushed by a. star-wheel 70 into a delivery receptacle 80 having shelves 81. Sliding weights 92 support the matrices on the shelves. When a shelf is full, the weight 92 strikes a pin 91 and withdraws a stop from a supporting arm so that the receptacle falls until the next shelf is in receiving position. A station. ary door 85 closes the filled shelves.
