Filed: 1943-05-05
Abstract: 565,415. Etching. WALPOLE, G. S., and MAUNDER, C. A. May 5, 1943, No. 7116. [Class 100 (ii)] In the production of nameplates, dials, dies, &c. by etching, the resist is applied to the surface to be etched by transfer under heat and pressure from a carrier bearing the resist. The resist on the carrier may be in the form of the required design or may be a coatng from which the required design parts are transferred by means of a heated die. In preparing an intaglio die, nameplate, &c., a foil coated with a resist is pressed by means of a heated die of the required design against a sheet of cardboard or other waste material. The resist remaining on the foil and corresponding to the background of the design is then pressed against the surface to be etched by a heated platen to effect the transfer. The resist may be strengthened against the action of the acid by rubbing the surface with grease, e.g. a candle, and then wiping, the grease thereby being removed from the areas not covered by the resist. After etching and removal of the resist, the intaglio areas may be filled with a coloured material, such as wax, paint or enamel. In preparing a relief die, nameplate, &c., the first transfer from the coated foil is made direct on the material to be etched and not on to a sheet of waste material. The remaining resist on the foil may be used to make a counterpart intaglio die.

In Fig. 4 the yarn catching members are hooks 14. When it is required to catch an end portion of the yarn 3 on the bobbin 1, a guide rod 11 is turned to a projected position shown in solid lines to displace the yarn 3 toward the cradle arm 2a. Thereafter the yarn 3 is turned over the bobbin 1 as shown in Fig. 4. When the cradle 2 is lowered towards the split drum 8 and the bobbin 1 is rotated by the drum, one of the hooks 14 catches a free end portion of the yarn 3 so that a wind-up of the yarn commences on an end portion of the bobbin. When a tail end has been wound the rod 11 is returned to its inoperative position shown in dot-dash line. This permits the yarn to be caught by a guide split of the split drum 8 so that normal traverse is commenced. In Fig. 9 the hooks 14 are replaced by cut-out portion 21 in the base disc portion 13c. The cradle arm 2a has a cut-out portion 22 in which is a cutter 23. To commence a wind-up operation the yarn is introduced into suction means above the cradle and a loop is drawn out over the bobbin 1 and manually introduced towards the cradle arm 2a in such a way that the yarn 3 enters the cut-out portion 22. In this condition the yarn is caught by one of the cut-out portions 21 and the free end of the yarn is cut by the cutter 23. The tail end is then wound as before.

Title: Process for the preperation of fusafungine
Inventor: SERVIER JACQUES
IPC: C07G11/00
Filed: 1963-02-25
Abstract: The antibiotic fusafungine is produced by cultivating Fusarium Lateritium WR, CSB 119.63 in a conventional culture medium therefore by deep culture with aeration at a rate of from 0.7 to 0.9 litres of sterile air per minute per litre of nutrient solution and simultaneous agitation, the pH of the culture medium being maintained within the range of 4.5 to 7.0 by means of one or more buffers.  A typical medium is an aqueous solution of saccharose, glucose, ammonium nitrate, sodium chloride, dihydrogen potassium phosphate and magnesium sulphate. Temperature of cultivation is 25 DEG  to 33 DEG C. and duration is 60 to 70 hours. The antibiotic is isolated from the mycelium or whole broth by extraction with a solvent such as methanol, methylethylketone, ethyl acetate or hexane. Further purification may be obtained by counter-current extraction of a hydrocarbon solution by a methanol-water mixture, followed by crystallization by the addition of water.  Fusafungine has antibacterial and anti-inflammatory properties and may be applied topically in the form of a solution, aerosol or ointment.
