Abstract: A packaging apparatus (e.g., otherwise described as a mailer apparatus with a material feeder assembly, a product supply assembly, a folding assembly, a sealing assembly, and/or a packaging apparatus system (e.g., including a controller thereof) for controlling the operation of the packaging apparatus. The packaging apparatus is configured for delivering products and material at the same time, and forming a package (e.g., a mailer, or other package) directly around the products. A material feeder assembly of the packaging apparatus supplies material for packaging and a folding assembly receives the plurality of products and folds the material around the products. The sealing assembly seals the material around the at least one product to form packages (e.g., makes a longitudinal seam, forms a transverse seam, and/or separates the material at the transverse seam).

Abstract: It comprises one or more cylinders with pistons therein and mutually opposed power cams connected to respective first and second rotary shafts. The reciprocating pistons act on the power cams to impart a rotating motion to the rotary shafts. An attachment device is provided for connecting the rotary shafts to each other. The attachment device includes a shifting device for changing the relative angular position of the first and second rotary shafts. The result is engine distribution and compression ratio are changed dynamically.
