Abstract: A hose built on a non-expanding, non-collapsing mandrel is removed readily lengthwise of and off the mandrel, facilitated by a tube of tough, flexible, thin anti-adherent film disposed in snug fitting contact with the length and girth of the mandrel. The tube is secured to the rigid metal member only close to the end thereof from which the hose is removed. Preferably, the tube is invaginated so as to provide inner and outer slidably juxtaposed walls. The hose built on such mandrel is moved lengthwise together with the outer wall of the tube which slides on the inner wall or the metal member. Lubrication, as by an air film, can facilitate the sliding, and does not contact the hose.

Abstract: This invention relates to apparatus and method for producing a composite container having a neck label or tubular sleeve mounted temporarily thereon adapted to be shrunken into final surface covering relation.

The sleeve preform comprised of heat-shrinkable plastic material is telescopically assembled onto the container while the latter is transported in spaced upright arrangement. The preform is moved downwardly by a pair of gripping vacuum cups moving downwardly and divergently to open the preform and place the same telescopically on the container upper portion. Alternately, the opened preform is placed on a cylindrical mandrel to more fully open the preform prior to its being mounted telescopically on the container neck portion.

Abstract: An article of manufacture for use in dental hygiene is disclosed. The device provides a leader, to which there is attached a thicker "mop" which can be comprised of a plurality of individual string members. The string members can be abrasive to enhance cleaning action.

Abstract: Circuit for controlling the program timer of a laundry dryer as a function of the moisture-dependent resistance of the laundry. A storage capacitor charged from a d-c voltage source together with laundry resistance resulting from wet laundry bridging two electrodes and resistance determine the duty cycle or frequency for an oscillator. The output of the oscillator is fed to a filter and from there as one input to a comparator. A reference value setter is fed to another input of the comparator. The output of the comparator is functionally connected to the program timer. This circuit arrangement makes possible measurement of low residual moisture values in the laundry and thereby permits the start of the post-drying phase without heating on reaching this low residual moisture value.
