Abstract: Devices and methods for shotshell cartridges, particularly shotshell cartridges with biodegradable components. One or more of the casing, shot wad, spacer, and powder wad may be formed of biodegradable materials. A biodegradable shot wad is manufactured of cellulosic fibers and wax to provide obturation and gas seal properties at high pressures with high reliability.

Abstract: A method of operating a DNP system comprising: a cryostat (1); a magnetic field generator (2) located in the cryostat for generating a magnetic field in a working volume; a microwave cavity (8) within which the working volume is located; and a waveguide (18) for supplying microwave power to the microwave cavity; the method comprising: a) locating a sample in the working volume and subjecting the sample to a magnetic field generated by the magnetic field generator; b) supplying liquid coolant to the working volume to cool the sample; c) irradiating the sample with microwave power so as to hyperpolarize nuclear spins in the sample; and d) warming the sample following the irradiation step by expelling liquid coolant from the working volume while leaving the sample in the working volume.

Abstract: A cutting apparatus includes a mandrel insertable in a food product container. The mandrel supports the container in a fixed position by contacting an inner surface of the container. The mandrel is locatable on a support apparatus so that as the mandrel and container are rotated on the support apparatus, the container remains in a fixed axial position. Spaced-apart cutting knives contact an outer surface of the container to cut the sample therefrom while the mandrel and container are rotated.

Abstract: An easy-open, spiral wound container for packaging refrigerated dough products includes a spirally wound fibrous core layer, forming an unbonded spiral butt joint. The container also includes an inner liner layer and an outer label layer, each having a seam. The outer label layer is weakened along the butt joint to facilitate opening of the container. An end closure member seals an end of the container.
