Disclosed is an improved assembly or matrix in which a plurality of open-ended, glass-ceramic tubes are disposed in axially parallel relation. The tubes are rigidified into a matrix structure, with the tubes being integrally bound to each other at their tube contact areas. Additional glass-ceramic material at and just below the surface of the matrix structure and arranged in a predetermined pattern across the open-ended face of the matrix integrally binds together the surfaces of the tubes facin...

A cabinet and kit for making the cabinet are disclosed in which the walls are structurally interlocked so that the cabinet can be assembled easily and quickly without tools. One of the interlocks comprise a pair of orthogonal channels and mortices which mate with orthogonal tenons. Another interlock comprises a mortice and tenon wherein a strap spans part of the mortice and locks with a bracket mounted in a recess in the tenon.

A container having a top, bottom and side panels and a locking closure, wherein the locking closure includes a closure panel and a tuck flap having foldable ears for engaging the underside of the closure panel.

A process for preparing alkoxides of the lanthanide elements, such as lanthanum, cerium, praseodymium and neodymium, in high yields and at increased reaction rates, is provided by reacting a lanthanide element with isopropyl alcohol in the presence of a catalytic amount of mercuric iodide or a mixture of mercuric chloride and mercuric acetate.

A refractory comprising 30 to 70% by weight of coarse refractory grain, and as an indispensable ingredient, of bonded structure for the coarse refractory grain titanium nitride, silicon carbide and alumina which are formed therein.

A knitted fabric provided with piles formed between the face and back side structures which are stitched to each other. The knitted fabric is manufactured by a way of knitting a bulky knitted fabric while forming piles and using a pile forming yarn doubled with one or both of a face structure forming foundation yarn and a back structure forming yarn between wales at which these yarns are all stitched together. The knitting is accomplished using a knitting machine wherein needle beds for pile for...
