Title: Dummy bars
IPC: B22D11/08
Filed: 1970-05-13
Abstract: 1317041 Continuous casting SCHLOEMANN AG 13 May 1970 [16 May 1969] 23278/70 Heading B3F [Also in Division E2] Adjacent sections (1, 2) of a starter bar for use in a continuous casting machine (see Division B3) are joined by a releasable connection comprising two connectors 3, 4 with projections 6, 5 for mutual interdigitation, the projections 6 having aligned bores 9 each communicating by a slot 10 with the projection edge and each being fitted with a rotatable cylinder 11 having a groove 12 alignable with and of the same width as the slot 10 to receive similarly-shaped reduced portions of a pin 13 journalled for rotation in sleeves 8 in aligned bores 7 of the projections 5 of the other connector. For interconnecting the connectors 3, 4, the reduced portions of the pin 13, exposed between the projections 5, are aligned with slots 10 and aligned grooves 12 so that the projections 5, 6 can be interdigitated before the pin 13 is rotated through 180 degrees to carry the cylinders 11 with it to the position shown, whereby the connectors are locked together, that is until the pin is rotated through a further 180 degrees to align the openings of the grooves 12 with the slots 10 to permit transverse withdrawal of the pin 13 with the projections 5. The connectors 3, 4 are hinged to the starter sections (1, 2). The end of the pin 13 has a square head 16 so that the pin can be turned by a spanner before a locking plate 17 is inserted in a recess 18 in the connector 3 to hold the head 16 against rotation. Grub screws 15 in the projection 6 engage grooves 14 in the pin 13 and in the cylinders 11 to hold the pin and cylinders against axial displacement. To prevent the slots 10 from being widened by force and to make the connector joint rigid, the connector 4 has locating pins 19 which fit into openings 20 in the connector 3. The interconnection can be released without extraction of a pin and in the guide apron.

Title: -a--ß- peltatin glucosides and process for their manufacture
IPC: C07H17/04
Filed: 1955-08-12
Abstract: The invention comprises a - and b -peltatin glucosides (C27H30O13, m.pt. 168-71 DEG  C., and C28H32O13, m.pt. 156-9 DEG  C., respectively) and a process for their extraction from Podophyllum peltatum L. characterized by extracting the drug with a water-soluble lower alkanol, concentrating the extract and then diluting it with water, treating the solution with tannin-precipitating agents, e.g. lead acetate, to separate the tannin-glucoside complex, separating the precipitate, freeing the residual solution from organic solvent, diluting it with water, removing impurities by extraction with a water-immiscible solvent, particularly chloroform, then shaking out the aqueous solution with a water-immiscible solvent containing approximately 1-10 per cent by volume of a water-soluble aliphatic alcohol, which extracts a mixture of glucosides containing Podophyllotoxin glucoside and b -peltatin glucoside (which mixture is then separated and the b -peltatin glucoside purified) and further extracting the remaining aqueous solution with a water-immiscible solvent, particularly chloroform, containing approximately 10-30 per cent by volume of a water-soluble aliphatic alcohol, thereby extracting a -peltatin glucoside and isolating it in solid form by distillation of the solvent.  Any resinous material in the powdered drug may be separated (either before or after the tannin removal) by extraction with a chlorinated hydrocarbon.  The mixture of Podophyllotoxin and b -peltatin glucosides is preferably separated by partition between water and water-immiscible solvents, e.g. chlorinated hydrocarbons or lower esters, either in a Craig counter-current apparatus or on a chromatogram column containing an absorbent, e.g. silica gel, diatomite or kieselguhr, and eluting with similar solvents containing a little of a lower alcohol.  In addition Podophyllotoxin glucoside can be isomerized with ammonia or other mild alkali into the relatively insoluble picropodophyllin glucoside and the unchanged b -peltatin glucoside then separated by extraction with water.  The crude a -peltatin glucoside fraction obtained after distillation of the solvent is similarly purified on a silica gel column, eluting with aqueous ethyl acetate and recrystallizing the glucoside from acetone.  Detailed examples are provided. Specification 768,919 is referred to.
