[Class 39 (i)] The luminescent properties of materials which have been impaired by fine grinding are improved by immersion in an easily volatilized acid solution, and thereafter drying so as to remove the solution. Screens so treated are more durable under electron bombardment. The concentration of the solution, time of immersion, &c. are determined empirically. The particles are ground small enough to pass through a screen of 200 to 400 mesh per inch. Synthetic willemite (Zn2Sio4Mn), cadmium phosphate, zinc carbonate, sulphate, or sulphide, uranyl fluoride, and calcium sulphide are mentioned as luminescent materials ; and for removal of the surface layer, solutions of carbonic, nitric, hydrochloric; phosphoric, or oxalic acid, and hydrogen sulphide. Material so treated may be applied to a support as by spraying, or with a brush, or by settling from air or liquid suspension ; and screens so formed may be used with X-ray apparatus, electron microscopes, image multipliers, or cathode-ray tubes. A method of forming a screen on a cathode-ray tube is described in which the particles are applied by settling from a suspension in an acid solution, so that the particles are treated at the same time as they are applied. The Specification as open to inspection under Sect. 91 states also that an alkaline solution may be used for removing the deleterious surface layer, and instances ammonium hydroxide, carbonate, or sulphide, tetramethylammonium hydroxide, and ethyl or other amine. This subject-matter does not appear in the Specification as accepted. Reference has been directed by the Comptroller to Specifications 410,159, [Group XX], and 456,755.

Title: Process for the preparation of new derivatives of penicillin
IPC: C07D499/26
Filed: 1948-09-14
Abstract: Penicillin is reacted with an organic base insoluble in water but soluble in organic solvents to form a derivative; pyrazolone bases, quinine and bases having the same ring-structure as quinine may be used and they may be natural or synthetic.  Alternatively, a salt of penicillin is reacted in an aqueous medium with a salt of quinine. In either method, there may be present a solvent which is partially miscible with water such as methyl ethyl ketone or chloroform.  In the examples: (1) aqueous potassium penicillin is acidified with phosphoric acid, extracted with chloroform and added to a chloroform solution of phenazone, when the desired salt is precipitated; (2) sodium, potassium or triethylammonium penicillin is dissolved in water and methyl ethyl ketone added; the solution is acidified, extracted with more methyl ethyl ketone and added to a solution of quinine hydrate in methyl ethyl ketone, the 1 : 1 salt being obtained by crystallization; (3) the quinine salt is obtained by the method of (1) from calcium penicillin, precipitation being caused by the addition of petroleum ether; (4) aqueous sodium or potassium penicillin is treated with methyl ethyl ketone and aqueous quinine formate added; the salt crystallizes out.  The penicillin used as starting material may be crude amorphous or pure crystalline, and may be a mixture of the various forms, penicillin G being specified. Cinchonine, cupreine and amidopyrine are also mentioned as suitable bases.ALSO:A salt of penicillin with a natural or synthetic base of the quinine or pyrazolone series is preparaed for injection by suspending it in oil or dissolving it in an organic solvent of higher viscosity than water, the resultant preparation being absorbed more slowly than a solution of a metallic salt of penicillin in a solvent such as B-phenoxyethanol.  There may be added wax or other agent acting by physical means.  Suitable bases are quinine, cinchonine, cupreine, phenazone and amidopyrine.  An example shows comparative rates of absorption of quinine penicillin in colza oil, calcium penicillin in phenoxyethanol and calcium penicillin in water.
