Abstract: A continuous motion sealer of a type typically employed for applying metallic foil seals to the mouths of containers for fluid comestibles is disclosed. The device includes means for cutting a flat seal of predetermined profile from a roll-supplied heat activated material, and transport the seal to the containers or other parts following which it is heat sealed. Improved camming means is provided which enables the sealing heater to engage a seal in the absence of other than vertical motion. A punch and die assembly includes a programmable electronic material advance mechanism. Each sealing head assembly includes an electronic band heater and thermocouple, as well as a vacuum pickup for individual seals. The thermocouple communicates with a separate sealing head temperature controller, programmable with regard to temperature setting, and an alarm connected to a system shutdown in the event of failure.

Abstract: A bank of PC board mounted low-power electric switches applicable to variety of functions is packaged in a common enclosure. The switches have a common matrix but are controlled independently of each other by respective sliders displaceable due to space limitations by pointed objects.
