Abstract: ABSTRACT       A laterally translatable roll apparatus supporting a continuous web of material, albeit for supply or take-up, is designed to maintain a roll in proper alignment as the web is paid from or rewound onto the roll. The apparatus comprises a pair of frame members to rotatably support the roll therebetween. A roll drive means has a drive shaft extending to one end of the roll. An interengagable coupler means is provided on both the output end of the roll drive shaft and the one end of the roll to permit the roll to be rotatably driven by the roll drive shaft while not being directly secured thereto. Means is axially mounted at the one end of the roll and biased to move axially outward away from the roll for engagement against the output end of the drive shaft. This axially mounted biased means may comprise a spring loaded plunger mounted in one end of the roll. Lateral translation drive means is mounted on the other of the frame members with translation output means engaging but not secured to the other end of the roll. Circuit means controls the lateral translation drive means to laterally translate the lateral output means which results in lateral translation of the roll without interfering with the rotational operation of the roll via the roll drive means. The lateral translation drive means may comprise a stepper motor mounted on the other frame member with its drive shaft in axial alignment with the rotational axis of the roll to apply translatory motion to the roll via the translation output means. An application for the laterally translatable roll apparatus is lateral translation of a recording medium roll in an electrographic printing or plotter system as the recording medium is paid from or rewound onto a medium roll to properly align the medium for desired aligned movement through one or more stations comprising such a system.

Abstract: ABSTRACT OF THE DISCLOSURE        Zeolite-metal catalysts having a substantial amount of catalytically active metal, e.g. iron, deposited in the cavities of the zeolite in zero-valent, small cluster form, are prepared by vaporizing the metal under low vapor pressure conditions in the vicinity of an organic liquid solvent, e.g. toluene, such that the metal dissolves in the solvent as a labile solvated zero-valent metal complex.  This complex is contacted with the zeolite so that the complex diffuses into the cavities of the zeolite.  Upon subsequent warming the solvated metal complex decomposes, leaving zero-valent small metal clusters in the zeolite cavities.

Abstract: ABSTRACT OF THE DISCLOSURE        Disclosed is a process for shirring tubular casings, in particular sausage casings, in which the casing is conveyed in the direction of its longitudinal axis and shirred against a counterforce by means of a shirring tool. The shirred tubing portion is divided into individual shirred sticks of a predetermined length and,  if appropriate, the cut-off shirred sticks are further compressed.  While being shirred and in the shirred state the casing is internally supported.  For cutting-off a shirred tubing portion, the transport of the casing in the direction of its longitudinal axis is momentarily interrupted, the internal support is withdrawn from the severing region, and the unshirred or deshirred tubing section is severed at the rear aperture of the shirring tool.  During severing, the not-yet-shirred casing surrounded by the shirring tool is permanently internally supported.       The apparatus for performing the process comprises a shirring mandrel composed of two mandrel members disposed within the tubular casing which, during the transport of the casing, are brought into flush contact.  The second mandrel member, seen in the direction of shirring, may be exchanged for at least one further mandrel member.

Abstract: ABSTRACT      Indoor pollutants such as formaldehyde can be removed from a house by a reactive method consisting of a coating on a furnace filter in a forced air heating system.  The coating is a polymeric substance with specific functional groups which react with the pollutant and which in the case of formaldehyde or other aldehydes such as acrolein or acetaldehyde would be a polymeric amine such as polyethylenimine.  In other cases it is possible to incorporate such polymeric amines into a paint which when applied to walls and ceilings can act as a reactive "sink" for aldehydes.
