Abstract: A continuously operating machine is provided for wrapping articles with a heat shrinkable plastic film automatically and sequentially. Articles are continuously, transferred along a horizontal pathway to a plurality of processing stations. At a first station, articles are tubularly overwrapped and sealed along a side edge thereof with excess film material being automatically trimmed away. Next, the articles are separated one from the other at a second station and at a last succeeding station, the resulting wrapped articles are subjected to thermal film shrinking. The side seal and trim apparatus includes a heat seal and trim unit which engages free side edges of the film tube to one another and trims excess away, the unit being sandwiched between drive and alignment members.

Abstract: A backfilling system for a liquid fuel tank of a vehicle using engine exhaust gas to prevent the accumulation of explosive vapors in the fuel tank. Exhaust gas is cooled, filtered and regulated in pressure before entering the fuel tank.

Abstract: An apparatus that consistently dispenses a predetermined volume of granular material into a receptacle, e.g., a coffee cup. The apparatus including container, guide, housing of three integral horizonal sections, plunger, spring and pin. Container stores granular material, e.g., sugar. Directly below container and secured tightly thereto cylindrical guide substantially same diameter as container neck and having vertically disposed opening therethrough. Guide can have funnel for directing granular contents toward opening. Directly below guide and tightly secured thereto is cylindrical housing. Upper section has guide way and stepped down opening in housing wall. Opposite this opening is pin partially embedded into housing wall and projecting into the guide way. Middle section of housing has vertically disposed outlet offset guide opening. Lower section of housing is substantially deep and has at least one perforation for directing steam out of housing.

Abstract: A kayak simulator machine is provided. The machine comprises a support assembly, a resistance-creating device coupled to the support assembly, a cord member coupled to the resistance-creating device, and a paddle-shaft coupled to the support assembly by the cord member. The paddle-shaft has opposite ends rotatably attached to the cord member whereby the paddle-shaft may be twisted relative to the cord member. The cord member is coupled to the resistance-creating device in such a manner that a pulling-resistance is imposed when the paddle-shaft is pulled, the pulling-resistance being greater than the pushing-resistance imposed when the paddle-shaft is pushed. The cord member is also coupled to the resistance-creating device in such a manner that the pulling-resistance is applied to the ends of the paddle-shaft. The paddle-shaft is coupled to the support assembly in such a manner that a center portion of the paddle-shaft may pivot in a three-dimensional pivot space.
