摘要:
The present invention provides a skylight frame design that is adapted to receive at least two panels of glass. The skylight frame comprises a stepped frame section that includes a lower step surface and an upper step surface. The lower step surface is adapted to receive a first glass panel so that a section of the first glass panel lies flush against the lower step surface. Similarly, the upper step surface is adapted to receive a second glass panel so that the second glass panel lies flush against the upper step surface. The skylight frame design of the invention is either incorporated into a skylight frame that may be attached to a curb unit on a roof or it may be an integral part of a skylight frame-curb assembly that also contains a curb section. In another embodiment of the invention, a skylight frame design which directly incorporates one or more panels of glass during molding is provided.
摘要:
The invention concerns a cyclic ether derivative of the formula I, ##STR1## wherein Ar.sup.1 is optionally substituted phenyl or naphthyl;A.sup.1 is (1-6C)alkylene, (3-6C)alkenylene, (3-6C)alkynylene or cyclo(3-6C)alkylene;Ar.sup.2 is optionally substituted phenylene, or a 6 membered heterocyclene moiety containing up to three nitrogen atoms;R.sup.1 and R.sup.2 together form a group of the formula --A.sup.2 --X--A.sup.3 -- wherein each of A.sup.2 and A.sup.3 is (1-6C)alkylene and X is oxy, thio, sulphinyl, sulphonyl or imino; andR.sup.3 is (1-6C)alkyl, (2-6C)alkenyl, (2-6C)alkynyl or substituted (1-4C)alkyl;or a pharmaceutically-acceptable salt thereof.The compounds of the invention are inhibitors of the enzyme 5-lipoxygenase.

摘要:
Apparatus for the continuous measurement of oxygen contained in a molten metal which comprises A. A SOLID OXYGEN ELECTROLYTE TUBE; B. A REFERENCE ELECTRODE HAVING KNOWN OXYGEN POTENTIAL IN CONTACT WITH THE INNER SURFACE OF THE TUBE; C. MEANS FOR MEASURING THE ELECTROCHEMICAL POTENTIAL PRESENT BETWEEN THE INNER AND OUTER SURFACES OF THE TUBE; AND D. INSULATING MEANS TO PROTECT THE SOLID OXYGEN ELECTROLYTE TUBE AGAINST CHEMICAL ATTACKS, THERMAL SHOCKS AND MECHANICAL STRESS DUE TO THE CONTACT WITH THE LIQUID MOLTEN METAL. The insulating means is a tube made of a metal containing substance having a high resistance to mechanical stress, to thermal shocks, to chemical attack, to splashing of the metal which is to be tested and to the slag of the metal which is to be tested. In addition the insulating means closely surrounds the solid oxygen electrolyte tube and is open at the bottom so that the outer surface of the tube can be directly contacted with the molten metal which is to be tested.
