Patent number: 9494539Abstract: A metal detector (420) has a metallic enclosure (421) with entrance and exit apertures (430, 431) whose cross-sectional areas differ from each other. Inside the enclosure is a coil system with a transmitter coil (423) and first and second receiver coils (424, 425). The apertures and the coil system enclose a detection zone (428) around a travel path on which objects under inspection move. The asymmetric detection zone has a variable cross-section along the travel path and the coils differ in size from each other. The receiver coils are connected in series, but their windings are wired with the opposite sense of rotation relative to each other. Energizing the transmitter coil generates a primary electromagnetic field that induces a first voltage and a second voltage in the corresponding receiver coils. Despite the asymmetry, the respective voltages cancel each other when no metal is present in the object investigated.Type: GrantFiled: August 1, 2014Date of Patent: November 15, 2016Assignees: METTLER-TOLEDO SAFELINE LTD., TNA AUSTRALIA PTY LIMITEDInventors: Daren Butterworth, Alfred Alexander Taylor, Darren Ken Alchin

Patent number: 9122940Abstract: An assembly to deliver packaging film, having a barcode, to a packaging machine (10). Associated with the packaging machine (10) is a splicing machine (17) that joins film from rolls (14, 15) for delivery to the machine (10). A barcode scanner (19) extends transversely of the film, with the scanner (19) including a plurality of cameras (29). Once a barcode is detected, as an example ten images will be decoded and if six “readings” give the same result, then it can be assumed that the barcode has been correctly decoded.Type: GrantFiled: April 5, 2012Date of Patent: September 1, 2015Assignee: TNA Australia Pty LimitedInventor: Michael Don Bray
