Abstract: This invention relates to novel anthelmintic compositions containing as the essential active ingredient, a compound of the formula: ##STR1## wherein R.sup.1 is cylcoalkyl, or optionally substituted aralkyl, aryl, pyridyl, or pyrazinyl;R.sup.2 is hydrogen, alkyl, cycloalkyl, alkoxyalkyl, alkylthioalkyl, cyanoalkyl, alkenyl, or optionally substituted aralkyl or aryl;R.sup.1 and R.sup.2 taken together with the nitrogen atom to which they are attached form an optionally substituted morpholino or piperidino group;R.sup.3 is hydrogen, alkyl, cycloalkyl, alkenyl, or optionally substituted aralkyl or aryl;R.sup.4 is alkoxy, haloalkoxy, dialkylamino, alkylthio, phenoxy or phenylthio; andR.sup.5 is alkyl, alkoxy, haloalkoxy, dialkylamino, alkylthio, phenyl, phenoxy or phenylthio; andX is oxygen or sulfur;And pharmaceutically acceptable metal salts and metal salt complexes thereof, and to methods of employing them in the treatment of intestinal parasites in animals, e.g. mammals, fish, and birds.

Abstract: Method and apparatus to heat fix a heat fusible xerographic powder image to a final support material in which the powder image is first transferred to a final support material and the image-bearing support material then brought into contact with a bath of hot liquid metal for a period of time sufficient to fix the image to the support material. The temperature of the bath is maintained at a temperature high enough to fuse the image but below that at which the support material is damaged. The liquid metal bath has floating on it a layer of molten non-metal to prevent oxidating of the metal and to precoat the support material on its entry into the bath to prevent particles of the liquid metal from embedding in the support material. The relative high density of the molten metal acts as a wringer to keep the plasticized coating very thin when drawn out of the bath.This is a division of application Ser. No. 500,411 , filed Aug. 26, 1974.

Abstract: A contact fuser assembly for use in an electrostatic reproducing apparatus wherein toner images are formed on various types of substrates, for example, plain paper and transparency materials such as cellulose acetate or polyester film. The fuser assembly is characterized by a provision of a plurality of fuser rolls forming a pair of nips through which the substrates pass in order to fuse the toner images thereto. Transport mechanism is provided for conveying the substrates to one or the other of the nips depending upon the particular material of the substrate. The surface of the roll provided for contacting the plain paper comprises a hard metal surface and the roll for contacting the toner images carried by the cellulose acetate, etc. comprises an elastomeric surface.

Abstract: Stripping apparatus for stripping copy sheets bearing electrostatic developed images from a heated pressure fusing roll after fusing of the images to paper sheets. The stripping apparatus comprises a flexible blade member supported by a retaining device and positioned into contact with the heated fusing roll surface. The tip of the blade has a hollow ground edge of a radius slightly greater than the fuser roll. The blade is slideably positioned to enable lateral expansion axially relative to the retaining device. A modification of the stripping device consists of a comb design with blade and retaining members having inter-locking tines.
