Abstract: Containers are transported on rotatable support plates which are arranged in a circle on a rotating turntable. The leading edge of a label is adhered to a container as it orbits past a vacuum-type label transfer drum. A curved guide which is tangential to the cylindrical body of the container as the orbiting and rotating container passes it causes the label to wrap completely around the container. One of a circular array of heat sealing elements which are rotating with the turntable adjacent each support plate is cammed radially outwardly of the turntable into contact with the region on the container where the trailing end overlaps the leading end of the cable. This fuses the ends of the labels together. The cam profile is adjustable in length to keep the time during which the heat sealing member is in contact with the label ends overlap constant independently of the rotational speed of the turntable.

Abstract: A system for remotely sensing the delivery of mail to a mailbox uses a transmitter mounted on the mailbox. The transmitter generates a prescribed signal when the door of the mailbox is opened. The system also uses a receiver adapted for placement at a location remote from the transmitter. The receiver has two receiving circuits. The first receiver circuit generates a mail arrival output in response to receipt of the prescribed signal from the transmitter. The first receiver circuit maintains the generation of the mail arrival output regardless of continued receipt of the prescribed signal, until receipt of a prescribed termination command entered by the user. This way, the user knows when the mailbox door has been opened. The second receiver circuit generates a receiver locator output separate from the mail arrival output in response to receipt of the prescribed signal from the transmitter.
