This disclosure provides a pre-mixed lost circulation treatment that can be pre-mixed ahead of time at a plant and delivered to a drilling site in one or more transport containers because the pre-mixture having a shelf life of at least one month and possibly longer. Because the components of the lost circulation treatment are mixed at a controlled mix site, the consistency of the lost circulation treatment is improved and can be better maintained from one lost circulation treatment to another. Further, one or more of the components of the pre-mixed treatment can be placed in a portable tote container that can be quickly and easily transported to the drilling site upon demand, or the tote can be delivered to the drilling site before a lost circulation zone is actually encountered.

A blender has a tubular mixing chamber that is provided with an interior and is arranged horizontally. A fill opening and an outlet opening communicate with the interior of the tubular mixing chamber. The fill opening and the outlet opening are spaced apart from each other in an axial direction of the tubular mixing chamber by a length distance. A rotatably driven shaft extends in the axial direction lengthwise through the interior of the tubular mixing chamber and is provided with mixing members that are projecting radially outwardly into the interior of the tubular mixing chamber. The shaft has a region without mixing members, wherein the region without mixing members is located in front of the outlet opening and adjoining the outlet opening. The region without mixing members has a length that amounts to between ⅕ of the length distance and ½ of the length distance.

A bowl assembly for a base driven appliance, the base driven appliance providing a primary drive coupling for the accessory assembly. The accessory assembly including: a bowl element that defines a reservoir; and a gear-box element having a secondary drive coupling and a secondary driven coupling. The bowl element defines a lower recess that removably receives the gear-box element, such that the primary drive coupling can engage the secondary driven coupling when the bowl assembly is supported by the base driven appliance. The secondary driven coupling is couplable to an accessory element that is operated within the reservoir, and such that the accessory element is operable by rotation of the primary drive coupling.

A magnetic mixing apparatus is disclosed. A magnetic mixing apparatus according to one embodiment of the present invention comprises: a shaft which passes through a driving motor unit and which is rotatably coupled to the driving motor unit; a first housing which is coupled to one side of the driving motor unit and which is provided outside a stirring container to accommodate an upper part of the shaft; a rotary rotor which is coupled to the end of the shaft at a stirring container side during normal operation and which has a first permanent magnet; and an impeller unit which is arranged inside the stirring container and which has a second permanent magnet magnetically coupled to the first permanent magnet during normal operation, wherein the first housing includes a magnetic separation rotary rotor support part formed to protrude inward so as to support, from the downward direction, the rotary rotor, which is down-driven so as to move downward from the shaft, when there is magnetic separation by which magnetic coupling is released through magnetic deformation of the first permanent magnet and/or the second permanent magnet.

A blender includes a container body to receive food; a blender body to support the container body; a container lid removably mountable to the upper surface of the container body to open and close the upper surface of the container body; and a discharge part provided at the blender body to guide the discharge of liquid or foreign matter accumulated on the upper surface of the blender body to the outside. Accordingly, foreign matter or liquid accumulated on the upper surface of the blender body is prevented from being introduced into a motor assembly, among others.
