Abstract: Epipodophyllotoxin - benzylidene - # - D - glucoside (I) is prepared either by (i) reacting epipodophyllotoxin - # - D - glucoside (II) with benzaldehyde in the presence of an acid catalyst, or (ii) methylating 41-demethyl-epipodophyllotoxin - # - D - benzylidene glucoside (III) with diazomethane. Compound (II) is obtained by alcoholysis of tetra-o-acetyl-epipodophyllotoxin-#-D-glucoside (IV) in the presence of an anhydrous zinc salt. Compound (IV) is obtained either by (i) condensing epipodophyllotoxin with [alpha]-acetobromoglucose, in an inert organic solvent in the presence of zinc or mercury oxide or (ii) condensing epipodophyllotoxin or podophyllotoxin with 2,3,4,6-tetra-o-acetyl-#-D-glucose in the presence of boron trifluoride ethyl etherate in an inert organic solvent at a temperature below 0 C. The compound (III) is obtained by reacting 41 - demethyl - epipodophyllotoxin with benzyl chloroformate to give the 41-carbobenzyloxy derivative which is then reacted with 2,3,4,6- tetra-o-acetyl-#-D-glucose in the presence of boron trifluoride ethyl etherate to give the tetrao-acetyl glucoside. The tetra-o-acetyl-41-carbo - benzyloxy - 41 - demethylepipodophyllotoxin-#- D-glucoside is hydrogenated to remove the carbobenzyloxy radical and dealkylated by methanolysis in the presence of zinc acetate and the resulting 41-demethyl-epipodophyllotoxin- #-D-glucoside is reacted with benzaldehyde in the presence of an acid catalyst. Pharmaceutical compositions having cytostatic activity and containing the above compound are administered, orally, parenterally or as a suppository.

Patent ES-366284-A1 (ES)
Title: Capacitor charge transferring arragements and circuits
IPC: H03H11/26
Filed: 1969-04-21
Abstract: A change is transferred to a capacitor C 1 connected between drain and gate of a field effect transistor from a capacitor C 0 connected between source and drain by a switching voltage source connected between the gate and the adjacent electrode of capacitor C 0 . The figure shows a binary shift register or an analogue delay line operable as a filter. During the first negative half cycle of a pulse source So current flows from an input signal source V i through a selective large resistor R 0 to correspondingly discharge a capacitor C 0 . During the next positive cycle current flows through T 1 to restore the charge on C 0 to a value equal to the voltage So less the threshold voltage of the transistor and this charge is withdrawn from an equal capacitor C 1 . During the next negative half cycle, C 0 is again discharged to the level of the signal and the charge on C 1 is transferred to C 2 . In this manner the charge is transferred progressively along the chain of capacitors. Multiphase switching may replace the two-phase shown in which case the capacitors are connected to the phases in groups. An integrated arrangement is described in which the capacitors are the enhanced gatesource capacitance of the transistors.

Title: Device for manufacturing a plastic tube
IPC: B29C48/12
Filed: 1969-10-29
Abstract: A device for manufacturing a plastic tube with transverse or helical grooves comprised of an extruder, and a die consisting of two movable halves forming a mold cavity with a ribbed profile through which the tube is extruded. The halves of the die are each provided with semi-circular elongated heating elements or members for heating a region between the opening of the extruder and the beginning of the die forming the mold cavity. One embodiment of the present invention uses an inflatable member disposed interior to the tube which when inflated forces the tube outwardly causing portions of the tube to conform to the grooves in the mold cavity to form a ribbed profile in the tube. The inflatable member comprises a movable cylinder having an inflatable wall and two expandable spaced apart end discs. Another embodiment of the present invention comprises an inflating member having two spaced apart expandable closing discs which, when expanded, communicate with the interior wall of the plastic tube thus, creating a high-pressure chamber therein. A spring-loaded valve for controlling the ingress and egress of the inflating medium, such as compressed air, into and out of the pressure chamber is situated between the two closing discs. The inflating medium trapped in the chamber under high pressure exerts a force on the tube thus, displacing portions of the tube into the ribbed profile in the mold cavity to form transverse or helical grooves in the tube.

Patent ES-422573-A1 (ES)
Title: Image scanning converter for automated slide analyzer
IPC: G01N21/17
Filed: 1974-01-24
Abstract: In an automatic slide analyzer an analog to digital converter is operated at the optimum speed while an address generator continuously generates the correct location in memory for the storage of the digital words. The image read-in system has a television type image scanning detector, a high speed analog to digital converter and an interface to a high capacity digital memory. The image of a leukocyte on a blood smeared slide is magnified and optically filtered. This image is scanned at conventional television rates by a vidicon camera tube. A timing pulse generator produces pulses which operate the analog to digital converter at the optimum time. An address generator concurrently generates digital addresses in the sequence in which the converted digital words are to be retrieved. In storage, digital words from successive scan lines are interleaved in the memory so they are in the correct order upon readout.
