Title: Tamper-indicating closure with drainage features
Inventor: GREGORY JAMES L
IPC: B65D41/04
Filed: 2000-04-19
Granted: 2007-02-20
Abstract: A tamper-indicating closure of integrally molded plastic construction that includes a base wall having a peripheral skirt with an internal thread for engaging an external thread on a container finish. A tamper-indicating band is connected to the edge of the skirt by a plurality of circumferentially spaced integral frangible bridges. A stop flange extends axially outwardly and radially inwardly from an edge of the band remote from the skirt for inversion and engagement with a bead on the container finish. The stop flange is in the form of a circumferentially continuous base of uniform thickness circumferentially of the band, and either uniform or increasing thickness radially and axially of the band. A plurality of circumferentially spaced lugs are integral with and extend from the base. The lugs widen uniformly from zero thickness at the band to a maximum thickness at the free edge of the flange. The lugs are thus disposed for opposed abutting engagement with the A1 diameter of the container finish beneath the A bead on the container finish. The channels or serrations between the lugs permit drainage of liquid from the area between the skirt and the container finish.

Title: An improved bulk material analyser for on-conveyor belt analysis
Inventor: SOWERBY BRIAN
IPC: G01N33/24
Filed: 1998-12-10
Granted: 2007-12-04
Abstract: The present invention relates generally to bulk material analysers suitable for the direct on-line analysis of materials such as coal and minerals. It is targeted particularly at direct on-conveyor belt analysis. It includes: a shielded enclosure defining an analysis zone within it and having a passageway through it to allow transport of bulk material through the analysis zone. At least one neutron source (1, 4) and at least two gamma-ray detectors (3, 5) are disposed within the enclosure to measure gamma-rays produced in the bulk material by both the neutron inelastic scatter and thermal neutron capture processes. A neutron source and a gamma-ray detector are arranged in either a transmission or backscatter geometry. A second gamma-ray detector is arranged either in a transmission or backscatter geometry with or without using a second neutron source. The arrangement of detectors is such that the bias in the spatial response of each, that is caused by the relative attenuation of neutrons and gamma-rays in the bulk material, at least partly compensates for bias in the spatial response of the other.
