Title: Antibiotics produced by fungi of the genus ustilago
Filed: 1950-11-14
Abstract: Ustizeain, a mixture of antibiotics, is produced by the submerged culture of fungi of the genus Ustilago in a nutrient medium containing the PO4 ion.  The nutrient medium comprises (a) a non-nitrogenous mineral base containing an aqueous solution of a number of the following ions: PO4, Mg, SO4, K, Na, Fe, Ca, Cl and Zn; (b) an organic carbon source selected from glucose, fructose, sucrose, cerelose, grape sugar, molasses and flour, and (c) a source of nitrogen especially KNO3, (NH4)2SO4, NH4Cl, NH4NO3, urea, yeast extract and fish solubles. Preferably, buffers, e.g. calcium carbonate and barium carbonate are present to prevent the pH falling below 4.5.  Growth factors such as yeast extract, distillers solubles, corna steep liquor and thiamin hydrochloride may also be present.  Grain infected with the fungus are shaken over sterile nutrient agar which is incubated at 28 DEG  C. for several days and pure colonies of the fungus Ustilago isolated therefrom.  The nutrient medium having a pH 3 to 8 is inoculated with the pure colonies and agitated with aeration at 15 DEG  to 35 DEG  C., and preferably 28 DEG  to 30 DEG  C., for 3 to 5 days.  The permeated medium may be centrifuged, the centrifugate treated with activated carbon and diatomaceous earth and the adsorbed antibiotics eluted with aqueous mineral acid.  The eluate is adjusted to pH 6.0 to 7 by alkali, treated with carbon and earth and eluted therefrom with aqueous acid ethanol at pH 6.0.  Alternatively, the fermentation liquor (and solids) may be extracted with water-immiscible solvents such as ether, chloroform, ethyl acetate and amyl acetate.  Ustizeain may be obtained by extracting the culture solids with methanol, adding water to the extract so formed, and extracting the dry precipitate with ether.  Ustizeain A is removed in the ether extract. Specified fungi of the genus Ustilago are Ustilago zeae, Ustilago avenae, Ustilago hordei, Ustilago kolleri and Ustilago spp.

Title: Improvements relating to brake gear for electric winches
IPC: B66D5/00
Filed: 1927-10-21
Abstract: 285,762. Demag Akt.-Ges, March 15, 1927, [Convention date]. Winches; driving-gear; self-sustaining gear.- A brake for winches is applied automatically by the load when hoisting ceases, but is released electrically when lowering under power. In the illustrated form the brake 20 is released during hoisting and power lowering by an axial movement of the shaft 11 towards the left caused by the magnetic tension of the stator field of the motor 8. When the motor is switched off, the magnetic field becomes inoperative and the shaft moves towards the right under the resultant pressure of the inclined teeth on the wheels 12, 13 to re-apply the brake. A spring 28 applies the brake with sufficient force to hold the unloaded hook or a light load. In winches fitted with motors without axially-movable armatures, a. separate magnet would be employed to release the brake.
