Abstract: A laminator for applying pre-printed labels to a single face corrugated web to form double face corrugated sheets utilizes a control system including accurate leading and trailing edge detection of the labels to custom cut the corrugated web to match the label length in a manner which assures complete and uniform coverage of the glued flute tips of the corrugated web by the labels. The labels are fed non-stop as a series of spaced sheets into a laminating nip to join the leading edge of the traveling single face corrugated web. A positioning nip upstream of the laminating nip varies the speed of the incoming sheets to accurately match sheet leading edge to web leading edge. Detection of the sheet trailing edge triggers operation of the web cut-off knife to accurately match the corresponding cut trailing edge.

Abstract: A proving switch is provided for an electromagnetic device for brakes and clutches having an energization coil energizable to attract an armature to a magnet body, the coil exhibiting increasing current flow therethrough upon application of an energization voltage thereacross, and exhibiting a momentary dip upon engagement of the armature and magnet body. Detection circuitry senses the current dip and provides a status signal in response thereto, confirming the engagement.
Abstract: A combustion apparatus utilizing an auger having an integral air supply system. The apparatus includes a cylindrical combustion chamber containing a rotatable auger. Waste is delivered to one end of the combustion chamber and is conveyed through the chamber by the auger, and ash and the non-combustible residue is discharged from the opposite end while the waste gases are discharged through a cyclone separator to remove fly ash. The auger is composed of a tubular shaft and a hollow spiral flight. Air is introduced into the downstream end of the shaft and flows through the hollow flight and exits through outlet holes in the flight into the combustion chamber. A portion of the air is introduced into the mass of waste being conveyed by the auger to provide primary air for combustion, while a second portion of the air is discharged from the flight into the upper zone of the combustion chamber above the level of the waste, to provide secondary combustion of the waste gases.
Abstract: An elevator system selectively moves and stops an elevator car at a plurality of landings in response to the operation of a signaling system wherein a controlled rectifier operates with a control circuit to command the stopping of an elevator car at a floor in response to the manual movement of a call button. An electromagnet has a coil connected to the gating circuit of the remotely located controlled rectifier and includes a core element having a first end connected to a first pole of a permanent magnet and a second end providing a pivotal support to an armature removably connected to a second pole of the permanent magnet. The manual call button is connected to a flexible, resilient member which is connected to the armature at a position located between the electromagnet and the permanent magnet and provides a snap action response.
