Patent FR-2213984-A1 (FR)
Title: Multipass zone refining plant - esp for silicon has smaller diameter coil than bar
IPC: C30B13/28
Filed: 1973-01-11
Abstract: For rapid traverse of the coil position from the tap end of the bar to the initial position at the base, between passes, the top clamp of the bar includes a bayonet coupling which is separated to allow the coil to be swung out of alignment with the partially refined bar of Si material. The coil has a dia less than that of the bar and the molten zone is waisted. The current supply to the coil is via slip rings outside the vacuum chamber along the vertical mounting pillar which has a turning drive mechanism for swinging the coil out of line, and then reintroducing through a molten gap in the seed crystal.

Title: Miniature chuck with longitudinal slots - has replaceable spring loaded jaws and and central shaft ejection
IPC: B25B9/00
Filed: 1973-03-28
Abstract: The fixture or chuck, is for use in production assembly of miniature cylindrical components.

Title: Three-phase supply phase asymmetry detector - converts two phases into coincident square waves for passing to logic detector
IPC: G01R25/00
Filed: 1974-09-20

In the case of neuroleptics, TRH potentiates their antipsychotic activity while reducing their extrapyramidal side-effects. Component (a) can be (i) a thymoleptic, e.g. imipramine, desimipramine, chlorimipramine, amitriptylin, protriptylin, prothiadene, doxepin, nomifensine or mianserin, or aMAO inhibitor, e.g. tranylcypromin, pargylin, phenelzin or nialamide; or (ii) a neuroleptic, e.g. chlorpromazine thioridazine, perphenazine, chlorprothixene, haloperiodol, reserpine, clozapine or sulpiride. Component (b) can be TRH itself, a 1-6C alkylamide of TRH, (pyro)-Glu-His-OH or its (alkyl)amide, (pyro)-Glu-His-pyrolidide. (pyro)-Glu-4-aminobutyric acid, or other derivs. of pyroglutamic acid. e.g. pyrrolidone-N-acetic acid and its amide.
