Title: Achieving water release zone for dewatering thick fine tailings based on shearing parameter such as camp number
Inventor: WEISS MARVIN HARVEY
IPC: C02F1/52
Filed: 2013-06-21
Granted: 2016-01-12
Abstract: Various techniques are provided in relation to flocculation and dewatering of thick fine tailings, with shear conditioning of flocculated tailings material in accordance with a pre-determined shearing parameter, such as the Camp Number. One example method of treating thick fine tailings includes dispersing a flocculant into the thick fine tailings to form a flocculating mixture; shearing the flocculating mixture to increase yield stress and produce a flocculated mixture; shear conditioning the flocculated mixture to decrease the yield stress and break down flocs, the shear conditioning being performed in accordance with the pre-determined shearing parameter to produce conditioned flocculated material within a water release zone where release water separates from the conditioned flocculated material. The conditioned flocculated material can then be subjected to dewatering, for example by depositing, thickening or filtering. The design, construction and/or operation of a flocculation pipeline assembly can be facilitated.

Title: Automated label and verification systems and methods for filling customer orders of medical items
Inventor: CARSON BRADLEY E
IPC: G16H20/13
Filed: 2013-07-16
Granted: 2021-08-24
Abstract: Systems and methods for filling a customer order. An automated label and verification machine is used to print and apply patient labels to products containing medical items and then verify the product label and patient label on each of the products. In order to supply the automated label and verification machine with a batch of different products making up the customer order, a user is sent to a storage carousel and prompted to pick the products from storage locations rotated into location adjacent to a door in the cage surrounding the storage carousel. The use of the storage carousels maximizes the number of distinct products and amount of those products that may be stored in close relation to the automated label and verification machine, thereby making the process more space and time efficient.

Abstract: Des adresses réassociables universelles peuvent être signalées depuis de multiples points dans l'Internet ou dans d'autres réseaux publics. Une adresse universelle peut être associée à une ou plusieurs adresses internes pour un fournisseur de sorte que, lorsqu'un trafic est reçu en un emplacement de réseau, le fournisseur puisse déterminer si le trafic doit être traité dans l'emplacement de réseau courant ou dans un emplacement de réseau différent, il est également possible de déterminer d'employer un processus statique ou processus dynamique sur la base d'un facteur parmi de nombreux facteurs. Si le trafic est destiné à un emplacement de réseau différent, le trafic peut être réassocié et acheminé à cet emplacement de réseau. Dès que le trafic est à l'emplacement destination déterminé dans le réseau, le trafic peut être réassocié et fourni à la destination finale. Les réassociations et les emplacements destination du réseau peuvent être ajustés à tout moment, sur la base d'un facteur parmi de nombreux facteurs, sans risque significatif d'interrompre le trafic.

Abstract: Apparatus and methods for providing reduced channel switching delays in a content distribution network. In one embodiment, switching delays are reduced by caching background content at reduced quality and/or resolution. A manager entity is provided which manages which, and how many, background channels are cached. Additionally, the manager entity may classify each device in the network according a status thereof. When a particular device is in one status or mode, background content is cached; however, when the device is in another status or mode, it will no longer require background content caching. The provision of background content and the determination of a status may be based on for example the user or device behavior and patterns, user preferences or favorites, bandwidth availability, time of day, subscription level, type of program, recentness of channel change requests on the device (or associated devices), etc.

Abstract: The present invention provides a method for production of cellulose ethers in a high solids process substantially without use of organic solvents as reaction and/or washing medium. In the method of the invention the first alkalization step is carried out by using high solids content cellulose pulp and solid sodium hydroxide. This is followed by an etherification step where the solids content is preferably further increased and the use of solid etherification reactant is preferred. As no organic solvents are used as reaction media the invented method enables production of cellulose ethers directly from never dried pulp with significant savings in energy and investment costs. The method is especially suitable for the production of carboxymethyl cellulose sodium salt (CMC) with low degree of substitution (DS < 0.3). The use of the resulting none or low water soluble carboxymethylated cellulosic fibres is suitable for example for producing microfibrillated cellulose.
