    Abstract: Disclosed is a filter assembly which includes rigid, perforated stainless steel tubes each of which is received in a removable, nylon mesh bag. Also disclosed is a still for reclaiming dry cleaning solvents which includes a free running auger component which is angularly reciprocated over the base of the still to dislodge the residue of the distillation process so that it can be flushed from the still by hot water.

    Abstract: This invention involves the orthodontic movement of live teeth in the mouth by using the forces of magnets. A magnet is attached to the teeth by conventional methods such as adhesive bonding or dental appliances. The magnets are placed on the teeth in such a manner to employ the attraction and repulsion characteristics of a magnetic field. These forces may be employed to align teeth, tilt teeth, move root positions and angulations, torque teeth, and erupt impacted or partially impacted teeth into the correct position in the mouth. The technique may be used alone or in combination with other conventional orthodontic techniques for either major or minor tooth movement. The magnets may be attached anywhere on a tooth, but preferably in an inconspicuous position. The magnets themselves may have tapered edges to insure the teeth move to the proper position. In the movement of a single tooth normally a magnet will be attached to the single tooth with the other magnet which creates the repulsion or attraction force being attached to several teeth in combination.

    Abstract translation: 本发明涉及通过使用磁体的力使活牙在口中的正畸运动。 磁体通过诸如胶粘剂或牙科器具的常规方法附着到牙齿上。 以这样的方式将磁体放置在齿上,以采用磁场的吸引和排斥特性。 可以使用这些力来对准牙齿,倾斜牙齿,移动根部位置和角度,扭矩齿以及爆发的冲击或部分冲击的牙齿进入口中的正确位置。 该技术可以单独使用或与用于主要或次要的牙齿运动的其它常规矫正技术组合使用。 磁体可以附着在牙齿上的任何地方,但优选地在不显眼的位置。 磁体本身可以具有锥形边缘以确保齿移动到适当的位置。 在单个齿的运动中,通常磁体将与另一个磁体连接到单个齿,从而产生组合地附着到多个齿的排斥力或吸引力。

    Abstract: An adjustable hinge is disclosed. The adjustable hinge includes a door jamb or frame leaf hinge plate and a door leaf hinge plate. The adjustable hinge includes at least one height adjustment spacer configured to a move a position of the door leaf hinge plate relative to the jamb hinge plate. The jamb or frame leaf incudes a set of holes for receiving spacers or shim buttons for adjusting a spacing of the jamb or frame leaf hinge plate relative to the door jamb. The door leaf hinge plate includes slots for receiving mounting hardware for adjusting a position of the door leaf hinge plate relative to the door's edge.

    Abstract: A method of lithium sorption recovery from natural brines and wastewaters. The method comprises introducing a feed lithium-containing brine to a sorption-desorption concentrating module in a form of a vertically mounted column filled with an inorganic granulated sorbent, being a chlorine-containing lithium aluminum double hydroxide. After the sorption, residual lithium-containing feedstock is drained from the column, then washing is made at a rate of at least 6 column volumes per hour in the amount of 150-250% of the sorbent volume, in the same direction as of the feed lithium-containing brine flow. Then lithium desorption from the sorbent is performed with desalinated water in the same direction as of the feed lithium-containing brine flow to obtain a lithium enriched solution. The obtained solution containing almost pure lithium chloride concentrate. The method results in reduced lithium losses with the washing solution and increased purity of the target LiCl concentrate.
