Title: Process for preparation of ultrapure thorium fluoride.
IPC: C01F17/00
Filed: 1983-01-27
Abstract: The specification discloses a process for the preparation of ultrapure thorium fluoride (ThF4) having minimized water content and consequent maximized optical transmission of 10.6 micrometer radiation.

The hydrated thorium fluoride is exposed to a reactive atmosphere of hydrofluoric acid vapor and a selected fluoride compound in the gas phase at elevated temperature for a predetermined period of time. The reactive atmosphere removes substantially all of the water and water-derived impurities from the hydrated thorium fluoride to produce ultrapure thorium fluoride which is highly transmissive to 10.6 micrometer radiation.

Patent ES-8706453-A1 (ES)
Title: Catheter for the treatment of constrictions, for instance in a blood vessel.
IPC: A61F2/958
Filed: 1986-04-03
Abstract: A catheter for opening constricted regions in the cardiovascular system includes an expandable dilatation zone comprising three dilatation elements arranged around a support tube. The dilatation elements are of tubular configuration, and each communicates at one end with a passage in the support tube leading to a pressure-suction pump. Constricted regions in the cardiovascular system may be enlarged or opened by introducing the dilatation zone into the affected site in a folded condition and expanding it peripherally therein. Upon expansion of the dilatation elements flow passages are formed between these elements, through which body fluid (for example blood) can pass with little resistance. The supply of body fluid to organs and tissues downstream of the affected site is thereby maintained. Interruption of the dilatation treatment is not required to insure this supply, thus permitting a substantial reduction in the overall duration of the medical procedure. The catheter may be employed, for example, to dilate blood vessels constricted by arteriosclerotic lesions and in valvuloplasty procedures, and may also be employed for treating constrictions in the esophagus.
