Granted: 1993-05-04
Abstract: ABSTRACT         This invention relates to a method of improving the dewatering of alumina trihydrate obtained by the Bayer process.  The method comprises treating the alumina trihydrate with the product of mixing an alkaline liquor and a C8 to C20 fatty acid, fatty acid precursor such as an ester or amide, or a fatty acid blend.  The product, a fatty acid salt, is an effective dewatering aid.         The alumina trihydrate may be washed with a liquor including said product, or the product may be added to a sayer liquor slurry prior to filtration of the alumina trihydrate.         The invention also contemplates a dewatering aid consisting of the product of mixing an alkaline liquor with a C8 to C20 fatty acid or fatty acid precursor.

Abstract: ABSTRACT    A strap comprised of a layer of magnetic material on a layer  of nonmagnetic  conductive metal  comprises a self-regulating heater, which is wrapped around a  length of heat recoverable  tubing disposed around a terminal being terminated to a conductor wire, or a pair of  wires being spliced.   When energized,  the strap  generates thermal energy melting solder  of a preform  within the tubing, terminating the terminal to the wire, or the  two wires  together,   and  sealing   the  termination simultaneously.  A plurality of terminals in a  connector housing include solder tails extending rearwardly from the housing so  that respective  wire ends  may be  placed therealong within solder preforms within heat recoverable tubing therearound.  A strap comprising a self-regulating temperature source is wrapped around the array of  solder tails and wire ends and is energized to solder the  array and seal the terminations.  A high frequency  alternating current induced in or transmitted to the magnetic layer of the strap causes the  strap to generate  thermal energy sufficient to melt the solder and shrink the tubing.  The strap may have  several layers and may be shapable  to conform to the outer  surfaces of the  heat recoverable tubing lengths.  A strap may seal an open end of a length of heat  recoverable tubing  having a  sealant preform therewithin, when wrapped therearound and energized.

Abstract: Objects constituted by a porous web-like material, such as a paper web, a granular material, such as peat, or a solid material such as wood, are dried by placing the same in contiguity with a fine porous liquid suction surface which itself is in liquid communication with a liquid volume with the latter being in communication with apparatus by which the liquid in the liquid volume is maintained at an underpressure relative to the pressure of the liquid in the object to be dried so that liquid flows from the object into the fine porous suction surface. The liquid flow can be enhanced through the application of an over pressure or through the direction of radiation onto the object to be dried. In one embodiment, the fine porous liquid suction surface comprises the surface of a rotatably mounted cylinder whereby a web-like object, such as a paper web, can be dried as the same is carried on the cylinder surface.

Abstract: Wellbores are cemented with a cement composition formed from drilling fluid occupying the wellbore by circulating a quantity of drilling fluid mixed with a cement material and a dispersant such as a sulfonated styrene copolymer with or without an organic acid into the wellbore to displace the drilling fluid and to continuously convert the drilling fluid into the cement composition. The cement composition may be recirculated through the space in the wellbore to completely evacuate any drilling fluid not converted to cement so as to minimize any faults in the cement composition occupying the wellbore. A preflush composition containing the dispersant and being rheologoically compatible with both the drilling fluid and the drilling fluid converted to cement slurry may be used as a displacement fluid.

Abstract: An apparatus monitors an a.c. motor (12), a door (14) operated by the motor, a frequency converter (16) for supplying electric power to the motor (12), and a control and signal-processing means (32) which causes the frequency converter (16) to control the door in accordance with a desired movement. The movement of the door is continously detected. The control and signal-processing means (32) compares the desired movement of the door with the detected movement, in order to emit an alarm signal (L) when the difference is too considerable. A switch means (28) thus blocks the power supply to the motor (12). A sensing means (31) senses whether the power supply to the motor (12) is blocked. The alarm signal (L) is repeatedly emitted in order to establish a possible malfunction of the switch means (28).
