    Abstract: A multi-use variable guard rail system for providing a safe working area is mountable on various surfaces, whether sloped (roofs), vertical (walls) or horizontal (floors). A rail support of the system has an upright pivotally engaged with a base, and a brace that locks the upright relative to the base in numerous positions ranging between an acute angle and an obtuse angle where the upright and base are linearly aligned. The upright has openings that hold rails such as various sizes of lumber in a vertically stacked array without the need to cut or fasten the lumber, and which allows for replacement of rails without disassembly of the rest of the system. The base has a tongue particularly suited for roof work, namely it is used to mount the rail support to the roof, yet allows the base to be lifted for placing shingles thereunder.

    Abstract: Polyamines containing at least two nitrogen atoms monosubstituted with pendant arms capable of coordinating metal cations, or with precursors of such pendant arms, all nitrogen atoms of the polyamines except two being fully substituted and the remaining two bearing one H atom each, are cyclized by reaction with a bridging agent that contains two sites that each bear a reactive group capable of undergoing a nucleophilic attack by one of the two N-H groups on the polyamine. Unlike the prior art, cyclization occurs in preference over polymerization of the polyamine, even in reaction mixtures in which the polyamine is at high concentration. A process is also disclosed whereby linear polyamines in which the terminal amine groups are primary amines are substituted with methylenephosphonate ester groups, with one such substituent on each nitrogen atom of the polyamine. The process involves the use of a trialkyl or triaryl phosphite, and unlike the prior art, monosubstitutions at all nitrogen atoms are achieved in preference over disubstitutions at the terminal primary amines. Finally, a novel class of N,N′,N″-tris(methylenephosphonate or methylephosphonic acid-substituted)-1,4,7-triazaheptanes are disclosed as new compositions of matter.

    Abstract: A dispenser/separator for contamination-free dispensing of a supply of cut-separable medical devices is disclosed which includes anti-contamination structure for enclosing the supply. The anti-contamination structure includes an exit port for allowing the supply to be pulled therethrough in a first direction to expose a device. Also disclosed is a cutter for separating such an exposed device from the supply by pulling the supply against the cutter in a second direction that is at an oblique angle relative to the first direction. In the preferred embodiment, the exit port takes the form of a resistance control aperture, and the cutter takes the form of a stationary knife blade that is positioned adjacent the aperture.

    Abstract: The sculpture is created by accreting successive layers of a vitreous material under close temperature control on a core to form a solid unified mass and of depositing pellicular images on one or more of said layers; said images, which may be photographically generated, being variously sinuous, discrete, diaphanous, colored and spaced apart from each other in both radial and axial directions of the solid mass which constitutes the sculpture and which is characterized by said images apparently floating freely within the mass composing a general design, scene, display or decoration.
