Abstract: Method and apparatus for controlling a machine which is operable in cycles, the machine carrying out a plurality of functions during each cycle. Values representing the stages of the machine in its cycle are generated as the machine progresses through a cycle, the values being determined by the actual stage of the machine independently of time. Starting and stopping points in the cycle for at least one of the functions of the machine is preset in terms of the generated values. The generated values are compared with the preset starting and stopping point values. The machine function is initiated and maintained when the generated values are greater than the preset starting point value but are less than the preset stopping point value and the function is stopped when the generated values equal or are greater than the preset stopping point value. Apparatus and method for computing starting and stopping points for an eyespot window using only a single set of delay switches is also disclosed.

Abstract: A liquid dispensing package from two continuous abutting strips having opposed recesses provided with spaced holes and forming substantially cylindrical chambers for individual ampoules. The strips are heat sealed together and non-woven fabric is heat sealed to the outer sides of said strips. Individual liquid dispensing packages are die-cut from strips with each having a peripheral flange. The liquid dispensing package can be manually crushed whereby the liquid in the ampoule penetrates through said fabric.

Abstract: A resealable package, comprising: a first, transparent member having a receptacle portion, a brim around the receptacle portion and structure forming one part of a snap-in lock formed in the brim; a second, flat member substantially co-extensive with the foldably connected to the transparent member along an edge of the brim opposite the snap-in lock structure, the second member having structure forming the other part of the snap-in lock, the first and second members being thereby detachably connectable; and, a removable sheet member, large enough to at least correspond in size to the first and second members and of relatively stiff material, interposed everywhere between the first and second members for reinforcing both the receptacle portion and the brim, the removable member having an opening through which only a portion of only the snap-in lock structure projects, whereby the members are held securely but releasably together.

Abstract: A stack of flexible packaging bags, such as used in the meat packing industry in conjunction with automatic and semiautomatic packaging apparatus, made by assembling a multiplicity of flattened stacked wicket-holed bags on a flexible tubing binding threaded through the bag wicket holes to define a severable loop handle element, shank elements passing through the wicket holes in the stacked bags, and shank portion extensions adapted to secure the shank portions of the binding to wicket mounting means and to mount bag stack securing means.

Abstract: Packing machines for the manufacture of packing containers frequently produce these from web-like material, which is supplied to the machine in the form of a roll. During the production the material web is advanced through the machine along a path defined by guiding rollers, guiding rails and similar elements. These guiding elements obstruct in an undesirable manner the movement of the material web through the machine. This difficulty is eliminated in accordance with the invention in that a front and a back part of the material web are advanced alternately. In accordance with the invention, moreover, an arrangement is proposed with first and second web-advancing elements, which operate with alternating working strokes.

Abstract: Overlapped foil wrappers are formed by feeding a foil web (1 or 21) at uniform speed from an upper pair of rollers (2 or 22) to a lower pair of rollers (5,6 or 25,26) rotating at a uniform slower speed. A first cutter (3,4 or 23,24) between the upper and lower rollers cuts the web at intervals of the overall length of a wrapper, and such that an overlap is formed by the time the newly cut leading end of the web is engaged by the lower rollers. A second cutter below the lower rollers cuts the web downstream of the overlap to form the short wrapper piece (loose front foil). The lower roller (6) may move away from the other roller (5) while the overlap is forming, allowing the distance between upper and lower rollers to be reduced.

Abstract: A button cell package in which button cells are releasably retained in position by an adhesive surface layer on a laminated structure having a resilient layer between the adhesive layer and a nonresilient base. An additional layer having preferential barrier properties is used with cells of the metal-air type and is located between the adhesive surface layer and the resilient member. The adhesive layer seals the metal-air cell to increase cell shelf life and prevents inadvertent dislodgment and loss of cell capacity, yet permits small amounts of evolved hydrogen to diffuse from the cell. The resilient layer serves as a cushion and provides a means for obtaining maximum surface contact between the adhesive surface layer and the button cell surface to maintain the cell in impact-resistant, releasable adhesive contact with the adhesive layer. The method of assembling the package is also described.

Abstract: This invention relates to an improvement in a sheathed, hollow, cylindrical stick composed of a flexible tube folded by longitudinal shirring, the improvement comprising a cylindrical, flexible jacket means enveloping said stick and projecting over the ends thereof, parts of the projecting portions touching end walls of said stick with their inner sides, annular disc means on said projecting portions, and said projecting portions being inverted outwardly around said disc means in a manner such that the inner walls, the end surfaces and the outer walls of said disc means are tightly covered, and said inverted portions being parallel to said jacket means and close to the exterior thereof. The invention also includes an embodiment wherein annular disc means are inserted inside the jacket means and adjacent to the end walls of the stick, the projecting portions of the jacket means are inverted around the annular disc means and clamping means are inserted in the opening of the annular disc means.

Abstract: Apparatus and method for opening an envelope upon three sides. The apparatus employs a circular rotating wheel which supports a plurality of complementary pairs of paddles which are designed to open at predetermined times to receive an envelope and close upon the envelope in a protective manner. The envelope is first received in the paddles with the leading edge thereof slightly exposed. As the paddles progress in their circular motion, the leading edge is engaged by means which weaken the edge. Thereafter, the paddles are opened and a conveyor below the paddles repositions the envelope between the paddles so as the trailing and bottom edges thereof are slightly exposed. As the paddles progress, the trailing and bottom edges are likewise weakened after which the envelope is discharged to an opening means.
