A storable, hydraulically-active, cementitious slurry is made and used to cement within subterranean foundations for oil and gas wells. The slurry is made from a hydraulically-active cementitious material, a suspending agent, and, as a retarder, boric acid. The boric acid is present in the cementitiou s slurry in an amount sufficient to lower the pH of the storable cementitious slurry to at least ...

The air cleaning robot includes a robot body, a driving part for driving a plurality of wheels disposed at lower portions of the robot body, an air cleaning part disposed in the robot body, for drawing-in dust-ladened air from a cleaning area, air filtering, and disc...

The robot cleaner has a cleaner body (12) which travels automatically around a cleaning area, a driving unit for driving several wheels mounted on a lower part of the cleaner body, and a suction unit mounted in the cleaner body to draw in dust on a floor. A negative-ion generation unit (11) is mounted in the cleaner body to generate negative ions, and a control unit is provided. While the robot cl...

The invention relates to a method and an apparatus for cooling a material to be removed from the grate of a fluidized bed furnace. Material at a high temperature is passed from the grate of the fluidized bed furnace into a fluidized bed cooler in charges of a given size by measuring the quantity of the material accumulating in the fluidized bed cooler. When the quantity of the material in the cool...

A washing machine is provided. The washing machine includes a tub, a sensor operatively coupled to the tub and configured to sense a conductivi ty of a fluid in the tub and a controller operatively coupled to the sensor for controlling an amount of the fluid in the tub based on the conductivity of the fluid.

Latch composed of a box (1, 4) inserted in which is a slider (2) controlled in translation by a spring (3) and comprising a hook (18) to catch a pin (9) placed on a guide of a drawer. A cam groove on the cover (4) of the box is travelled along by a ball (23) disposed on the slider (2) and held pressed by a spring (22) against the bottom of the groove to determine the four open, closed, released an...

Between two layers ( 10, 12 ) of Bretonstone(TM) mix-formed by inert materials ( 11 ), a hardening resin and a filler ( 13 )-at least one fibrous middle layer ( 14 ) is arranged which consists of linear elements or inorganic filaments ( 15 ), preferably made of glass and in the form of continuous non-woven elements, pre-impregnated with a resin of the same kind as, or compatible with that forming ...
