A lift-off adhesively erasable typewriter ribbon contains, in a pigmentatious layer on the substrate strip, in addition to the pigment and a resin binder, a halogenated hydrocarbon modifier containing at least 14 carbon atoms serving to embrittle the resin binder and facilitate transfer of the layer from the ribbon to the paper during the writing process and to allow clean and adhesive removal of print if a correction is required.
摘要:
The invention relates to a tube dispensing device (10) for squeezing out the content of a tube using two pressure plates (12, 13), which are disposed transverse to each other at the pressure sections (15, 16) thereof, at least in the case of a lack of a tube to be squeezed, wherein a base (11) is provided, from which the pressure sections (15, 16) protrude. In this manner the tube may be stored standing up, and may be completely emptied.
摘要:
A pressure-sensitive copying material consisting of a sheet-like base to which has been applied a coating comprising microcapsules containing dyes. The microcapsules are filled with a solution or suspension of a salt of a dye base and an organic carboxylic acid in an organic water-immiscible solvent. The copying material is distinguished by exceptional non-smudging characteristics and is particularly suitable for the production of business forms.

摘要:
In a method or filling paste tubes and apparatus therefor, the ointment is filled into a plastic skirt designed for once-only use and then introduced into the tube by means of this plastic skirt. During the filling of the ointment into the tube, a part of the plastic skirt not moistened by the ointment is made to cover the inner parts of the bottom end of the tube, so that these parts are protected against being moistened by the ointment. The method and apparatus may be used for the manual filling of tubes with a pasty mass, especially when making up prescriptions.

A method of treating viral diseases in a human subject is disclosed. The method involves applying effective amounts of the compound: ##STR1## wherein X is an azido group, a methoxy radical or a fluorine atom and B is thymine, uracil, guanine, cytosine, purine or hypoxanthine if X is methoxy or fluorine, and B is guanine, purine or hypoxanthine if X is azido or a pharmaceutically acceptable salt thereof. Also disclosed are compositions and compounds useful in the method.
