Feeding device for feeding burned lime to a reaction vessel for causticizing soda liquor to caustic soda. The feeding device, in its upper part, has an inlet for receiving slurry of the burned lime and the soda liquor for formation of said slurry inside said feeding device. The system further comprises a tall and slender feed vessel having a lower part having an outlet defined therein for the slurry. The outlet, via a pump, is operatively connected to the reaction vessel. The process and the feeding system utilize the feeding device, in which process the slurry is created of the burned lime and a first part of the soda liquor, a second part being preheated before addition to the slurry, whereafter slaking and causticizing reactions are completed under elevated temperature and pressure.

An improved paint roller frame that permits switching between two paint rolling directions or between two tilted painting angles. The frame comprises a roller cage assembly, a shaft for receiving the roller cage assembly, and a handle for supporting the shaft. The handle or its extension pole comprises two substantially elongated members being releasably fastened with a fastening means. Each of the mating ends of these two handle members has an oblique end section to which the normal is inclined with respect to the longitudinal axis of the corresponding handle member at an angle of approximately 5 to 45 degrees. The roller handle or its extension pole may optionally have a second set of oblique sections, to which the normal is inclined with respect to the handle axis at an angle of approximately 5 to 45 degrees. The second set of oblique planes are inclined at an angle of approximately 45 to 90 degrees with respect to the first set. One set of the oblique planes can be used for tilted painting angle adjustments while the other for paint rolling direction adjustments.

Paint roller frame with an adjustable handle

A handle for a paint roller that can be used to paint horizontally (left and right, or 90-degree direction), vertically (up and down, or 0-degree direction), or any angle between 0 and 90 degrees by simply adjusting the roller handle-shaft configuration; said configuration possessing one of the following features: (1) having at least one transverse hole, making an angle of approximately 90 degrees or less with the handle length, which can accommodate a telescopic rod; (2) comprising two detachable handle segments wherein one segment has at least one transverse hole to accommodate one end of the second handle segment or a telescopic rod; (3) comprising at least a wire coil, female thread, near one end of the shaft, that constitutes a transverse hole to accommodate the male thread of a handle or a telescopic rod to facilitate horizontal paint rolling. In each case, the opposite end of the handle could optionally have one vertical hole to accommodate a telescopic rod.
