Provided are a refractory article, an anti-redox coating composition, and a method of manufacturing the refractory article. The refractory article includes: a platinum (Pt)-based substrate; and a coating layer for preventing a redox reaction on a surface of the Pt-based substrate, wherein the coating layer for preventing a redox reaction includes on an oxide basis SiO.sub.2 in an amount of about 40 wt % to about 70 wt %, Al.sub.2O.sub.3 in an amount of about 20 wt % to about 52 wt %, B.sub.2O.sub.3 in an amount of about 3 wt % to about 6 wt %; and CaO in an amount of about 2.4 wt % to about 4.8 wt %.

Systems and methods have demonstrated the capability of rapidly cooling the contents of pods containing the ingredients for food and drinks.

A mixing blade for a mixer for concrete, mortar, powders, dry or semi-dry granulates, mixtures with a cement base or similar or comparable mixtures or mixes comprises a shank which develops along a longitudinal axis and a mixing wall connected inclined to one end of said shank, transverse to the longitudinal axis. The mixing wall comprises, on one side of the longitudinal axis, a first front mixing plate, and on an opposite side, a second front mixing plate angled backward toward the longitudinal axis with respect to the first front mixing plate, by an angle of inclination of the plate.

The present invention pertains in general to an apparatus and method for the infusing, agitation and dispensation of oils in a controlled manner to produce a desired potency of an infusion while remaining below an identified maximum temperature threshold.

There is provided apparatus (301) for mixing contents of a receptacle, the apparatus comprising a rotary shaft (302) equipped at a proximal end with a connection for removable attachment to a means of providing rotation. The rotary shaft has a mixing element (303) fixedly connected at a distal end of the shaft opposite to said proximal end. The mixing element comprises at least two arms (304) at the distal most end of the shaft, a corkscrew neck (306) on the shaft and a collar (305) on the shaft positioned in between the at least two arms and the corkscrew neck. The at least two arms are configured in a first partially-open resting position and are moveable to a second fully-open operative position. The mixing element further comprises a blade (307) positioned across the shaft more proximally than the corkscrew neck.

The present invention pertains in general to an apparatus and method for the drying and activating of infusing material, and the infusing, agitation and dispensation of oils in a controlled manner to produce a desired potency of an infusion while remaining below an identified maximum temperature threshold.

A mixing agitator, for industrial use in mixing processes, that overcomes disadvantages associated with glass coated mixing agitators in the prior art. In particular, the mixing agitator includes a glass coated metal hub radially symmetrical about a central axis. The hub is at least partially embedded within a fluorinated polymer. The fluorinated polymer extends beyond the hub and forms agitator blades that may be reinforced. The hub has a centrally located receiving portion for receiving a drive shaft for rotating the agitator. The agitator is lighter weight than prior art glass coated steel agitators yet still has excellent chemical resistance and good temperature resistance. The agitator of the invention reduces likelihood of glass damage and permits agitator blade shapes not useable by glass coated agitators in the prior art. The invention also includes a mixing apparatus incorporating the hub and a method for mixing using the agitator.
