Abstract: A liner-less seal application system is programmed to generate a real time seal, the serial number of which is data-matched with product label data on an approach product article. The image is printed in the required position (to suit the article being sealed), onto the adhesive surface of the seal tape. A vacuum drive belt has both low and high vacuum sections to assist in moving the sealing tape along a vacuum drive belt toward the print head. The real-time seal is printed while the belt drive indexes the tape, and the cutting action is done while the system collects data and the belt drive is stationary. There is only one stepper motor employed to drive the vacuum belt. The vacuum belt drive pulls the tape from the unwind assembly and feeds the tape through the print head and onto the vacuum drum applicator. A perforator device bursts perforation across the round element of the seal image. This is to apply a weak point on which the seal will break if tampered with.

A perforator device bursts perforation across the round element of the seal image, as an anti-tampering measure.

Abstract: A label application system for liner-less pressure sensitive adhesive-backed labels comprises a label sensor disposed at a junction between a drive roller and a vacuum belt. When the leading edge of a passing label is detected, the drive roller is stopped, while the vacuum drive belt continues to advance, thus pulling the label in question distally, relative to its trailing connected label, which is stopped on the drive roller. This applied force functions to separate the label from its trailing label, along a micro-perforation between the two labels, following which the separated leading label travels along the vacuum belt and is applied to an article passing on an adjacent conveyor system.

Abstract: A process and apparatus for automatically monitoring or adjusting, or both, the concentration of total reducers (i.e. reduced sulfur-containing constituents which consume iodine) in an aqueous medium (e.g. waste water stream) whereby the time period for iodine titration of an untreated sample of the aqueous medium is automatically measured by measuring a time of light being transmitted through a titration sample cell and this time measurement is automatically translated into an output signal to either a monitoring means or a process adjustment means (e.g. oxidant chemical feed pump) or both.
