A process for recovering weight material for reuse in drilling fluids from a previously unavailable source of feed stock. The process described herein includes a process of cleaning drilling waste through either low temperature thermal or solvent washing to remove hydrocarbon or water based drilling fluid contamination. The cleaned drilling waste, substantially free of liquids is sifted and the bulk fraction is further treated by employing conventional separation technology to recover a high gravity solids phase while discarding low gravity solids phase as tailings. Additionally, described is a process where the recovered high gravity solids phase can be reused as a high density weight material, or lower cost weight material, either of which is desirable to the drilling of modern oil and gas wells. The process of adding drilling fluid back into the recovered weight material to simplify the process of transporting the weight material into an active drilling fluid system is also described.

A devices (10) and method for pasteurizing and/or sterilizing particulate material. The device contain at least one electron source (20) for generating an electron beam and a treatment zone (19) in which the material is pasteurized and/or sterilized by the electron beam. The device (10) comprises a vibration surface (11) which vibrates to convey and individualize the material. The first vibration surface (11) has a plurality of grooves (12) into which the material is conveyed and individualized. The device (10) has a material channel (21) in which the material is pasteurized and/or sterilized by the electron beam in the region of the treatment zone (19). The device (10) has at least one auxiliary channel (22) through which a fluid flows, between the electron source (20) and the material channel (21), and is separated from the material channel (21). A cartridge (24) for pasteurizing and/or sterilizing particulate material is also disclosed.

A carrier link to convey at least one pellet-shaped article along a predetermined conveyer path in a direction of travel includes at least one pocket adapted to receive a pellet-shaped article and a lead-in surface provided to an upper exterior surface of the carrier link and extending into leading edges of the pocket. Each pocket includes a longitudinal axis that is transverse to a direction of travel of the carrier link. The lead-in surface provides a ramped or declined surface into the pocket to facilitate entry of the pellet-shaped article into the pocket. The lead-in surface is ramped or declined towards a side of the carrier link to facilitate rotating, guiding, and/or orienting of the pellet-shaped article into the pocket.

The device (10) has a good channel (21) in which the material is pasteurized and/or sterilized by the electron beam in the region of the treatment zone (19). The device (10) has at least one auxiliary channel (22) through which a fluid flows between the electron source (20) and the good channel (21) and is separated from the good channel (21). A cartridge (24), for pasteurizing and/or sterilizing particulate material, is also disclosed.

A material sorting system sorts materials utilizing a vision system that implements a machine learning system in order to identify or classify each of the materials, which are then sorted into separate groups based on such an identification or classification determining that the materials are composed of either wrought aluminum, extruded aluminum, or cast aluminum.

A method for the optimized operation of a transport container conveyor system for items of cargo, in particular of an airport luggage conveyor system, includes: a) introducing an item of cargo into the conveyor system at an introduction point; b) providing larger transport containers of a first category and smaller transport containers of a second category for receiving a respective item of cargo; c) automatically recording a dimension of the item of cargo; d) depending on the recorded dimension, automatically assigning the item of cargo to a transport container of a first or second category; e) automatically loading the assigned transport container with the item of cargo; f) transporting the transport container loaded with the item of cargo on active conveyor sections; g) repeating the above steps for further items of cargo. There is also described a novel conveyor system.

A mail item sortation system and method that includes an external controller for culling candidate letters in a mailing job to produce groupings of letters based on industry average weights and/or thicknesses in order to place all the candidate letters going to a single address adjacent to each other, an internal controller, interfaced with the external controller, that utilizes the groupings of letters to manage multiple letter sorters, wherein a specific letter sorter is selected to pair a calculated number of pockets to accommodate the groupings with an actual number of pockets in the selected letter sorter, and a transfer process for moving letters within the letter sorter pockets to a StatementPack machine.
