Abstract: A printer blank for a computer system printer is disclosed. The blank has a contiguous pressure adhesive backed label section and may also have a larger plain paper section separated from the label section by a perforation line. The label section is comprised of a plurality of adhesive backed labels and a backing sheet, including a main label portion and at least one smaller auxiliary label. A preferred blank comprises a plurality of auxiliary labels. In use, at least one, but preferably not all, of the auxiliary labels on such a preferred blank are simultaneously removed from the backing sheet with the main label portion. Any auxiliary label(s) simultaneously removed with the main label but not printed upon are readily separated from the main label.

Abstract: A tape dispensing apparatus including a tape container having tape dispensing apertures and a plurality of slots for partitions between rolls of tape. The partitions in the slots are individually formed from portions of boxes for the tapes. The portions of the boxes are integral with the boxes with the tapes therein but have lines of demarcation from the remainders of the boxes for being torn therefrom.

Abstract: A method and device for qualitatively detecting the presence of blood in urine by comparing the color of the urine to a plurality of colors corresponding to the relative blood content of the urine, which enables a health care provider to roughly identify the stage of hematuria and to decide on an appropriate course of action.

Abstract: A cover for servicing holes in automotive service stations consists of a band of pivotably connected support members, the ends of which are supported on the longitudinal hole edges. The band is displaceable longitudinally in opposite directions by at least one motor drive to open and close the servicing hole. During the opening movement the band is moved downwardly at one front end of the longitudinal hole. In order to avoid a broadening of this region of the hole the support members are telescopically assembled and are compressed to a reduced length in this region than in the covering region of the servicing hole.

Abstract: A dental floss applicator is composed of a U-shaped frame of resilient material having a plurality of parallel slits in each one of the pair of holding arms. A plurality of unit lengths of dental floss are fastened in the slits of the arms thereby forming a dental floss curtain. The unit lengths ae provided with caps or beads at their ends and are of equal length. The interspace between a pair of caps or beads of each dental floss unit has an over-dimension with respect to the space between the arms of the frame. The unit is fastened at the frame by turning the unit at least partly around the base of each arm not containing the slit of slits thereby forming a 180.degree.-half-loop or a 360.degree.-whole-loop of the unit. The dental floss curtain provides for a better cleaning operation between the teeth and the new fastening mode guarantees a secure arrangement of the unit at the frame even when the unit is in a slack condition.

Abstract: In a wrap-around packaging machine by means of which a film loop is wrapped around a plurality of objects, the film passes through a slit provided in a rotary tensioning roller at an end of which a driving pulley is fastened. A rope is wound around the driving pulley. One end of the rope is connected to a traction device and the other end is connected to a restoring device. The tensioning roller by the operation of the traction device can be rotated from a first defined position in which the film freely passes through the slit of the tensioning roller into a second position in which the film is clamped at the tensioning roller and the film loop is tensioned. Then after welding or heat sealing of the film loop the traction device is made inoperative and the restoring device operates in order to move back the tensioning roller into its defined first position.
