Title: Process for the separation and purification of tetracyclines antibiotics
IPC: C12P29/00
Filed: 1965-01-01
Abstract: A tetracycline antibiotic is isolated from a culture liquid by solubilizing the antibiotic present in a culture liquid at pH 2-3, precipitating the tetracycline antibiotic by the addition of an inositolhexaphosphoric acid salt and adjustment of the pH to 7.0 to 7.5 with ammonia, separating the precipitate and treating it with a solution of a complexing agent and ammonia at pH 9.0 to 9.5 to bind any heavy and alkaline earth metals present in the precipitate, adding oxalic acid to pH 2.5 to 3.5 to convert the tetracycline antibiotic into its oxalate and extracting the resulting precipitate with a solvent appropriate to the desired tetracycline antibiotic. It is preferred to use calcium, or calcium and magnesium, inositolhexaphosphate.  The sequestering agent is ethylene diamine tetraacetic acid.  The antibiotic may be tetracycline, oxytetracycline, chlortetracycline or bromtetracycline.

Title: Means for automatically operating capstan lathes or other machine tools
IPC: B23Q11/00
Filed: 1942-01-05
Abstract: 551,594. Lathes. COHEN, R. Jan. 5, 1942, No. 153. [Class 83 (iii)] An automatic control-mechanism which may be embodied in an attachment to an existing capstanlathe or other machine tool normally operated by hand, comprises fluid pressure cylinders controlled by oscillating valves actuated automatically in any desired sequence. Thus in Fig. 6 the chuck-operating mechanism 6, the capstan slide 4, and the cross slide 5 may each be operated by a cylinder m mounted on the machine. The supply to the cylinders is controlled by a number of oscillating valves b each comprising' a fixed bar c and a bar d which can oscillate on a pivot o, Fig. 3. The fixed bar has ports h leading to atmosphere and ports e connected to pressure supply lines g. Pipes k connected to ports f in the rocking bar lead to opposite ends of the cylinders so that one end of the cylinder is connected to pressure and the other to exhaust. To reverse the cylinders the bar d is rocked alternately in opposite directions by strikers s on cam discs r arranged on a pair of intergeared shafts p. The shafts p are driven at a variable speed from the lathe drive-shaft x through worm gearing w and friction wheel u adjustable radially with respect to a friction disc t. The shaft of the wheel u is supported in an adjustable frame z and carries a freely rotatable wheel which prevents deflection of the friction disc. Instead of forming an attachment the control may be built into the machine. In some cases only a single cam-disc-carrying shaft may be employed. The device may also be modified for the use of oil or other fluid instead of compressed air.

Abstract: 587,104. Pulse generating systems. RADIO GRAMOPHONE DEVELOPMENT CO:, Ltd., and COURT, E. T. Jan. 4, 1945, No. 399. [Class 40 (v)] [Also in Group XXXV] In an arrangement for generating an elongated impulse in a circuit controlling the flow of A.C. for adjustable short periods, a starting circuit which may comprise a switch 13, condenser 34 and resistance, 35 is energized from a D.C. supply 15, 16 by the closure of the switch 13 to produce a positive impulse which is applied to the grid 33 of a valve 12 which is normally held non-conducting by bias voltage in a cathode resistance 29 common to valve 12 and a valve 11 which normally carries a high current. Valve 12 becomes conducting and reduces the potential at the anode of 24 and the current through the normally conducting valve 11 rapidly falls until valve 12 reaches a saturated condition. This stable state is maintained for a period dependent upon the time constant of the coupling circuit between the two valves, comprising condenser 25, resistance 32 and potentiometer 30, after which period both valves return to their original stable states.

Title: Separation of ore and clay-like materials
IPC: B07B13/00

Abstract: 1,069,471. Concentrating ores. W. R. GRACE & CO. Jan. 6, 1965 [Feb. 20, 1964], No. 623/65. Heading B2H. A mineral ore is separated from a mixture of the ore and clay-like material by subjecting the mixture to pressure between two surfaces, at least one of which is elastically deformed by the ore in the mixture, and separating the two surfaces to release the pressure and to permit removal of the separated ore from the clay-like material adhering to one or both of the surfaces. The process may be applied to the separation of ores such as diamonds and barites but is particularly useful in the treatment of phosphate ores. The term "clay-like material" is defined as including clays, i.e. hydrous silicates of Al, Fe or Mg, and similar sediments or sedimentary rock obtained when mining the ore. The apparatus may include rotating belts or reciprocating plates but, preferably, the mixture, which may be a slurry of phosphate ore matrix in water, is fed continuously from a hopper 8 through the nip of a pair of rollers 1, 3 of which one has a surface 3 of elastically deformable material, e.g. rubber, and the other has one of solid, smooth steel. Alternatively, both rollers may have electrically deformable surfaces. As the rollers are rotated by drive means 4, the mixture is pressed and flattened by them, the clay-like material adhering to one or both of the roller surfaces while the ore deforms the or both surfaces and falls freely between the rollers. Water may be sprayed on the roller surfaces through nozzles 10, 11 to help remove the clay therefrom in conjunction with fixed or movable scrapers 5, 6. The spacing between the rollers may be adjusted by means 7 connected to one of the rollers. The speed of rotation of the rollers may be varied.

Title: Picture-in-picture image storing method
Inventor: GUILLON JEAN-CLAUDE
IPC: G09G1/02
Filed: 1997-05-22
Abstract: Image display system with storage of data of images to be displayed. Image display systems are known which can at the same time display an image of a first source (MP) and an image of a second source (RP), with the image of the second source (RP) being reduced in its spatial dimensions. In order to permit a simultaneous image display, the two images are separately stored and processed. According to the invention, the two images are stored in a single memory (4). Prior to the storage a processing of the image of the second source is carried out and this image is stored on a consecutive-line basis in the line scan gaps of the image of the first source in the common main memory. The line scan gaps of the image of the first source are utilised for storage. During the period of the line scan gaps, a) that line of the second source which is to be stored is split up into two parts or b) the subsequent line of the first source is delayed (21). The invention is employed in image display systems. <IMAGE>
