Abstract: A pressure threshold sensitive adhesive product which exhibits substantially no adhesive tack except upon the application thereto of a threshold pressure, e.g. about 50 pounds per square inch is disclosed. This adhesive product comprises a substrate having coated thereon a layer of a normally tacky, pressure-sensitive adhesive and a top layer of microspheres, preferably hollow microspheres, in an amount sufficient to cover the immediate adhesive layer. The application of the threshold pressure causes the microspheres to be displaced thereby exposing the normally tacky adhesive. The adhesive product is preferably manufactured by preparing a suspension of the microspheres in the normally tacky adhesive composition, coating the suspension on the substrate and promoting the microspheres to migrate to the top of the suspension and to form the top microsphere layer.

The bars are printed on a bright white substrate and have a width of at least one-eighth inch so as to permit at the least eight lines per inch of type to be printed on the form. The bars are of at least two different repeating colors and of such a spacing as to effectively avoid confusion and minimize eye fatigue when reading lines of type spaced as closely as eight or more per inch.

Abstract: Apparatus for controlling the infeed speed of a web of material relative to the outfeed speed so that damage to the web will be minimized. The control apparatus senses the length of a loose loop formed by the web and includes a moving belt provided with perforations along its length and which is, in part, positioned between a vacuum chamber and the downwardly depending portion of the web loop. The downwardly descending portion of the web loop is held in contact with the adjacent surface of the perforated belt by a low level vacuum in the vacuum chamber and the position of the loop, with respect to the number of the holes in the belt covered by the downwardly descending portion of the loop, regulates the degree of vacuum in the vacuum chamber. As the loop lengthens, the vacuum increases in a vacuum chamber behind the belt, conversely, when the loop shortens, the vacuum in the chamber decreases. A signal corresponding to the vacuum in the vacuum chamber is communicated to a pressure transducer-amplifier.
