Title: Cephalosporin salts and injectable compositions
IPC: C07D/
Filed: 1986-08-01
Abstract: Cephalosporin Salts and Injectable Compositions Crystalline sulfuric, di-nitric, mono-hydrochloric, dihydrochloric, and di- and sesqui-orthosphosphoric acid addition salts of 7-¢.alpha.-(2-aminothiazol-4-yl)-.alpha.-(Z)-methoxyimino-acetamido!-3-¢(1-methyl-1-pyrrolidinio)-methyl!-3-cephem-4-carboxylate are stable even at elevated temperatures. The crystalline sulfuric acid addition salt is made by forming an admixture of (a) at least one molar equivalent of sulfuric acid with (b) zwitterion in an amount so as to be present in the admixture at a concentration of greater than 25 milligrams/ml, causing crystallization, separating the crystals, washing and drying. The crystalline monohydrochloride, dihydrochloride, and orthophosphate salts are prepared by dissolving the zwitterion in the appropriate amount of acid, causing crystallization by adding acetone and isolating the crystal. Physical admixtures of the salts with certain bases in proportions to give a pH ranging from about 3 5 to about 7 on dilution with water provide injectable compositions on dilution. Brief Description of the Drawing Figure 1 is a graphical representation of the infra red absorption spectrum of crystalline 7-¢.alpha.-(2-aminothiazol-4-yl)-.alpha.- (Z)-methoxyiminoacetamido!-3-¢(1-methyl-1-pyrrolidinio)methyl!-3-cephem-4-carboxylate sulfate salt measured on a KBr dilution thereof.

Patent BR-0211775-B1 (BR)
Inventor: ACKERMAN MICHAEL COLIN
IPC: B23K26/00
Filed: 2002-08-07
Abstract: A method of forming a workpiece (18) comprises: holding the workpiece adjacent a mould (20); using a laser (30) to heat at least a part of the workpiece to a temperature sufficient induce superplasticity; and applying a fluid pressure to the workpiece, so that it takes the shape of the mould. This has the advantage that the superplastic properties of the material can be used to form the workpiece precisely to the required shape, without needing to heat all of the processing chamber to the superplastic temperature. Before using the laser to heat the workpiece to its superplastic temperature, the laser can be used to heat the whole of the workpiece to a substantially uniform temperature to anneal it. Similarly, after using the laser to superplastically form the workpiece, the laser is used to heat the whole of the workpiece to a substantially uniform temperature to remove any residual stresses. This has the advantage that the whole of the forming can be carried out as a single process, in a single processing apparatus.

Inventor: KALIAGUINE SERGE
IPC: C01G49/00
Filed: 1999-07-15
Abstract: Metal oxides having a perovskite or perovskite-like crystal structure are prepared by a process comprising subjecting a mixture of starring powders to a high energy milling sufficient to induce chemical reaction of the components and thereby directly mechanosynthesize said metal oxide in the form of a perovskite or a perovskite-like material having a nanocrystalline structure as determined by X-ray diffractometry. The process according to the present invention is simple, efficient, not expensive and does not require any heating step for producing a perovskite that may easily show a very high specific surface area. Another advantage is that the perovskite obtained according to the present invention also has a high density of lattice defects thereby showing a higher catalytic activity, a characteristic which is highly desirable in their eventual application as catalysts and electronic conductors.
