Abstract: An automatic power line disconnect apparatus has a sensor pin for signaling the separation of the plug from the disconnect apparatus. The operative movement of the sensor pin is shorter than the length of the male electrical connectors on the apparatus, thereby insuring that the apparatus is disconnected from the power line before the electrical connectors' contact is broken to reduce electrical connector erosion from arcing. A motor driving a rack and pinion gear combination responds to an engine starter signal by driving the rack in a direction that disconnects the power line plug from the automatic disconnect apparatus. Further circuits are provided to lock out low voltage starter signals, photoelectric detectors to control movement of the rack, and timer circuits to limit the duration of the motor operation and to lock out starter signals when the disconnect apparatus is being separated from the power line plug.

Abstract: An apparatus includes a connector which, in use, is connected to a shore cable. The shore cable provides power to a vehicle. A connection in the apparatus to the vehicle's starting circuit actuates an ejector mechanism when the vehicle's engine is started. The ejector mechanism ejects the shore cable from the apparatus and a switch interrupts the current prior to the completion of the ejection action, thereby preventing arcing at the connector and assuring long contact life.

Abstract: This automatic battery charging circuit has two independent channels for charging first and second batteries respectively. Circuit control means in the battery charging circuit enable it to provide charging current in proportion to the state of charge of the two batteries. First and second electronic bar displays are connected to the two channels by wires. The channels provide readings which indicate the state of charge of each battery. The state of charge of each battery is sensed only when no charging current flows to each battery. Computer components in the circuit control means compute the charge level of each battery and this charge level is indicated by the respective bar displays.

Abstract: A fabric-marking system employs applicator pads resiliently urged into opposed contact with upper and lower surfaces of a fabric for affixing a defect marker onto one or both surfaces of the fabric. The defect markers are supplied on a tape-type carrier strip. The defect markers include a pressure-sensitive adhesive and the carrier strip includes a release coating to permit the defect markers to be stripped therefrom. A leading defect marker is partly stripped from the carrier strip by being passed over a stripper bar. The partially stripped defect marker is disposed between the fabric and its applicator pad. The applicator pad is urged into contact with the portion of the defect marker that projects between the applicator pad and the fabric. Continued motion of the fabric strips the remainder of the defect marker from the carrier strip and the applicator pad irons it in place as it slides therepast.

Abstract: A decal transfer press for transferring thermally transferable images from paper backings to cloth articles such as T-shirts has an upper platen which is motor driven into pressure engagement with a lower platen when an operator depresses a control lever after initiating a brief start-up interval during which a heater of low thermal mass fastened to the underside of the upper platen attains a preset decal applying temperature. The upper platen is automatically stopped in the down position by deenergizing its drive motor when the pressure the upper platen applies to the lower platen, as manifested by the drive motor armature current, exceeds a preset amount.
