摘要:
A self-contained vacuum apparatus having a housing with an air inlet aperture for receiving debris, a dustbag in the housing communicable with the air inlet for storing received debris, a suction motor communicable with the air inlet aperture for generating suction at the aperture to draw the debris into the dustbag, an air outlet aperture communicable with the suction motor to exhaust air from the vacuum apparatus, and an on/off switch for activating the vacuum apparatus, the vacuum apparatus being mountable in a cavity to locate the air inlet aperture adjacent a floor surface so that debris urged towards the air inlet aperture is drawn into the dustbag upon activation of the on/off switch.

A lighted architectural mesh includes a plurality of interconnected wires forming a plurality of transverse openings. At least one light carrier is slidably received within at least one of said transverse openings. The at least one light carrier includes light nodes emitting light through the interstices on the front and/or rear side of the architectural mesh. The at least one light carrier further comprises a plurality of connecting elements, wherein the light emitter nodes of the at least one light element are releasably interconnected in series by the connecting elements.

An architectural mesh sunscreen panel having at least a first portion including a first architectural mesh assembled from a plurality of first interwoven helically-wound spiral units and first connector rods; and a second portion including a second architectural mesh assembled from a plurality of second interwoven helically-wound spiral units and second connector rods. The first architectural mesh defines a first shading characteristic that is different from a second shading characteristic defined by the second architectural mesh.

Dyestuffs of the formula: ##SPC1##In whichR.sup.1 is H, benzyl, sulphobenzyl or an alkyl group of 1-4 carbon atoms which may be substituted by OH, CN, OSO.sub.3 H, CO.sub.2 H, halogen, SO.sub.3 H or NHQ, Q representing a cellulose-reactive group,R.sup.2 is H, or an alkyl group of 1-4 carbon atoms which may be substituted by OH, CN, OSO.sub.3 H, CO.sub.2 H, halogen or SO.sub.3 H, orNr.sup.1 r.sup.2 is the N-linked radical of a nitrogen-containing heterocyclic compound containing 5 or 6 atoms in the heterocyclic ring,R.sup.3 is H or an alkyl group of 1-4 carbon atoms which may be substituted by OH,R.sup.4 is benzyl which may be substituted by SO.sub.3 H or NHQ, an alkyl group of 1 to 4 carbon atoms which may be substituted by OH, SO.sub.3 H or NHQ or a phenyl radical which may be substituted by SO.sub.3 H, CO.sub.2 H, halogen, alkyl or alkoxy of 1 to 4 carbon atoms or NHQ, and the benzene ring A may be further substituted by an alkyl or alkoxy group of 1-4 carbon atoms, halogen, NO.sub.2 or NHQ, and wherein NR.sup.1 R.sup.2 and NR.sup.3 R.sup.4 are different and the dyestuff as a whole contains 1 or 2 cellulose-reactive groups and at least one further SO.sub.3 H group.The dyestuffs are particularly suitable for dyeing cellulose textile materials in the presence of alkalies to give bright reddish or violet shades having good fastness to washing. The light fastness of the new dyes is much better than could have been expected from the known fastness of basic xanthene dyes applied to cellulose with the aid of mordants.
