Cultivation is preferably at pH 6À5-7À5 and 26-32 C. submerged in aerated liquid medium. The antibiotic may be isolated by filtering off the medium, drying the mycelium and washing it with an organic liquid in which the antibiotic is insoluble, e.g. butyl acetate, drying the mycelium in vacuo, and extracting the Nyphimycin therefrom with a suitable solvent, preferably aqueous ethanol. The ethanol is distilled off under reduced pressure to leave an aqueous suspension of the antibiotic, which is cooled, filtered and the filter cake washed with water and dried to give the required antibiotic. Pharmaceutical compositions having antifungal activity comprise Nyphimycin together with a pharmaceutical carrier, and may be in unit dosage form. The antibiotic also inactivates herpes virus and inhibits the growth of carcinoma cells.

Abstract: 425,504. Vehicle spring-suspensions. BAILEY, R. W. H., 36, Ashbourne Road, Derby. Jan. 29, 1934, No. 3001. [Class 108 (ii)] In road vehicles an independent wheel suspension is provided in which both the inclination of the wheel to the horizontal and the distance of the wheel from the chassis frame are maintained constant. The chassis a carries a member g, Fig. 3, to which are pivoted upper and lower lovers or chassis brackets a<4> of equal length to keep the inclination of the wheel constant. To the outer ends of these brackets are centrally pivoted vertical levers g3, to the lower ends of which are pivoted radius rods g<2> pivoted at their other ends to extensions g<1>. The upper ends of the levers g<3> carry the stub axle member h. In operation on upward and downward displacement of the wheel axle e the centres of the levers g<3> approach the chassis frame a. Meanwhile, the lower ends of the lovers g<3> also approach the chassis frame a to a greater extent since the radius rods g<2> are shorter than the brackets a<4> causing the upper ends of the levers g<3> and with them the stub axle e to recede from the chassis frame, maintaining a constant distance if the parts are correctly proportioned. In another form the brackets a<4>, Figs. 6 and 7 are journalled to a member in which is fulcrumed a lever j<2> connected by a radius rod d to the extension d<1>. At the other and divided end of the lover j<2> is fulcrumed at k<1> a lever k connected by the other radius rod d to a similar extension. The inner end of lever k carries the pivot l for the stub axle which is maintained at a constant distance from the chassis frame.
