Abstract: The present invention relates to an electrical distribution board. The electrical distribution board comprises at least one incoming conductor terminal, at least one outgoing conductor terminal, at least one longitudinal bus conductor connected to the at least one incoming conductor terminal, at least one lateral conductor tab connected to the at least one bus conductor for distributing electrical power from the at least one bus conductor to the at least one outgoing conductor terminal, and at least one isolation mechanism for electrically isolating the at least one outgoing conductor terminal from the at least one lateral conductor tab. The at least one isolation mechanism is moveable between a first position in which the at least one outgoing conductor terminal is electrically isolated from the at least one lateral conductor tab and a second position in which the at least one outgoing conductor terminal is electrically connected to the at least one lateral conductor tab.

Abstract: A shock prevention device for an electrical distribution board having at least one incoming terminal and one or more bus conductors for distributing electrical power from the incoming terminal to a plurality of outgoing conductor terminals projecting from a housing of the distribution board, the shock prevention device comprising an insulating body adapted to receive and shroud at least one conductor terminal; a moveable element moveable relative to the body so as to place the device in one of a first configuration in which the device can be fitted to or removed from the distribution board so as to cover the exposed terminal and a second configuration in which the device is braced between the conductor terminal and part of the distribution board housing, whereby removal of the device is prevented; and means for locking the moveable element in the second configuration.

Abstract: Fluorinated alkoxy compounds of copper, copper-calcium, copper-strontium, and copper-barium having the structure:Cu.sub.W (OR).sub.X Y.sub.Y L.sub.Z ; orM.sub.a Ci.sub.b (OR).sub.c,in which 1.ltoreq.w.ltoreq.4; R is a fluorinated alkyl group; x.gtoreq.1; Y is an alkoxy or alkyl group without beta-hydrogen; y.gtoreq.0; w.ltoreq.(x +y).ltoreq.2w; L is a Lewis base; 0.ltoreq.z.ltoreq.2w; M is Ca, Sr, or Ba; and 1.ltoreq.a.ltoreq.4; 1.ltoreq.b.ltoreq.4; (b+2a).ltoreq.c.ltoreq.2(b+a), have exceptionally high volatilities, and hence low vaporization or sublimation temperatures, at 10.sup.-5 torr. They are superior precursor compounds for chemical vapor deposition of thin films on substrates under vacuum, and for sol-gel processing.

Abstract: The invention relates to precursors useful for the preparation by CVD of superconducting thin films. The precursors are the volatile alkoxides of the formula M(OR).sub.2, wherein M is selected from the group consisting of Ba, Ca, and Sr, and R is selected from the group consisting of unsubstituted alkyl groups of 6 to 13 carbons and halogen substituted alkyl groups of 3 to 4 carbons wherein the halogen is selected from the group consisting of fluoride and chlorine and at least two of the halogen substitutions are fluorine. The secondary or tertiary alkyl groups are preferred and the tertiary alkyl groups are most preferred.

Abstract: The invention relates to volatile mixed metal alkoxides of the formula M'.sub.x M.sub.y Cu.sub.z (OR).sub.x+2(y+z) wherein M is selected from the group consisting of Ba, Sr, and Ca, M' is an alkali metal, x=0-6, y=0-4 and z=1 to 6, and x and y are not 0 at the same time, and R is selected from the group consisting of CMe.sub.3, CMe.sub.2 Et, CMeEt.sub.2, CMe.sub.2 Pr, CMeEtPr, CEt.sub.3 or combinations of these substituents. Volatile alkoxides of Y and Cu are known. These volatile alkoxides can be used in a CVD process where stoichiometric quantities of the material are sublimated, transported to a substrate and decomposed to an oxide with or without the presence of oxygen. The oxides are then treated in a known manner to produce the superconducting film.
