IPC: G03B42/04
Filed: 1971-01-01
Abstract: 1308892 Dishwashing machines FRAME SA 1 Jan 1971 [29 Jan 1970] 180/71 Heading A4F A spraying rotor for an industrial glassware or dishwashing machine has a main arm 1 rotatably mounted at its centre for rotation by the reaction of liquid expelled from a jet 7 Fig.2 (not shown), and carrying at each end a rotary sprayer 3 supplied with liquid through the arm 1, and thrust in each sprayer 3 in opposition so that imposed by the fluid pressure within it is provided by openings 19 in the sprayer wall 10; located around its axis of rotation and through which liquid passes to form a liquid cushion between each sprayer 3 and a cap 14. The latter is fastened to the axle 12 on which the sprayer 3 is rotatably mounted, and a plastics sealing ring 20 is secured to the wall 10 adjacent a flange on the cap 14. Similarly a plastics ring 18 surrounds the space between the apertures 15, 16 through which liquid passes from the arm 1 to each sprayer 3. The sprayers 3 are rotated by the reaction of the jets of fluid discharged therefrom, one sprayer having two inclined nozzles 4, and the other having one inclined nozzle 4, a laterally directed nozzle 6, Fig. 2, (not shown) and a vertical nozzle 5. The nozzle 5 may be coupled by a rod 25, Fig. 7 (not shown), to the axle (24) on which the main arm 1 rotates, so that the nozzle 5 moves in a circular path above which inverted glassware may be arranged in a circle. In an alternative embodiment the axle 12 is secured to the lower wall of the arm 1.

Title: A new antifungal antibiotic hamycin and process for its manufacture
Filed: 1961-01-03
Abstract: <PICT:0950351/C2/1>   The invention relates to the production of the antibiotic Hamycin, by inoculating an aqueous nutrient medium containing inorganic salts, nitrogenous compounds and carbohydrates with a culture of an antibiotic Hamycin-producing strain of Streptomyces pimprina, allowing aerobic fermentation to take place and recovering "Hamycin" from the fermentation broth. The fermentation is preferably carried out at 26-28 DEG C. for 72-84 hours. The Hamycin is isolated by filtering the fermented broths washing the mycelium with chloroform and extracting the washed mycelium with an aqueous aliphatic alcohol containing 1 to 5 carbon atoms. The extract is concentrated, the solid formed separated and washed with benzene, water and methanol. The washed product is dissolved in a hot aqueous alcohol of 1 to 3 carbon atoms and activated charcoal is added and the product filtered to give amorphus Hamycin. The antibiotic Hamycin is characterised by (a) I.R. maxima at 3, 3.45, 4.35, 5.8, 5.85, 6.1, 6.15, 6.21, 8.5, 9.35, 9.9, 11.8 and 12.5 microns (see Fig. 1) (b) U.V. maxima at 230, 285, 345, 363, 383 and 406 mm  in 80% methanol (see Fig. 2); (c) no definite melting point; (d) elemental analysis of 58.2% carbon, 8.3% hydrogen and 2.1% nitrogen and (e) insolubility in water, benzene, chloroform and <PICT:0950351/C2/2> dry aliphatic alcohols of 1 to 5 carbon atoms but solubility in basic solvents e.g. pyridine and collidine, in aqueous aliphatic alcohols of 1 to 5 carbon atoms and in 2% methanolic calcium chloride.

Filed: 1944-01-12
Abstract: 608,124. Casting composite articles; powder metallurgy. GENERAL ELECTRIC CO., Ltd., PRICE, G. H. S., and WILLIAMS, F. M., [Representative of WILLIAMS, S. V.]. Jan. 12, 1944, No. 603. [Classes 83 (i) and 83 (iv)] In a process for making a metal body comprising at least one metal of relatively high melting point such as tungsten or molybdenum and at least one metal of relatively low melting point such as copper or silver, a compound of the high melting point metal is first reduced in a container and is then soaked while still in the container with a low melting point metal in molten form. The invention is intended more particularly for making contacts for circuit-breakers or welding electrodes. Tungstic oxide is lightly packed in a recess or recesses in a graphite slab and is heated for approximately two hours at a temperature of 1000‹ C. in an atmosphere of wet hydrogen to reduce the oxide to tungsten. In order to strengthen the porous mass of tungsten produced, the temperature is raised to 1300‹ C. for 30 to 60 minutes to promote sintering, which may be facilitated by the addition to the tungstic oxide of nickel or nickel oxide powder in such quantity that the percentage of nickel does not exceed ¥ per cent of the tungsten content. The tungsten is then saturated with copper or silver while still in the graphite container, either by dropping molten metal on to it or by placing pieces of the metal on the surface of the tungsten and then melting them. Approximately 76 per cent copper or 78 per cent silver may be absorbed. Specification 564,905 is referred to.
