The frequency of the alterning field is varied to obtain the optimum results.
Patent CA-2093549-A1 (CA)
Title: Drain Trap
Inventor: LAI SHU-YING
IPC: E03C1/282
Filed: 1993-04-06
Abstract: A drain trap includes an L-shaped inlet tube, a cap, a vertical discharge tube and a garbage blocking member. The inlet tube includes a vertical portion, a horizontal portion having an end integral with the lower end of the vertical portion, an open upper end and an open lower end. The cap closes the open lower end of the inlet tube so that water falling from the open upper end of the inlet tube strikes an inner wall of the cap. The discharge tube has an open upper end and is connected securely to  the upper surface of an intermediate section of the horizontal portion of the inlet tube so that the drain trap is generally F-shaped,  thereby defining a return area in the horizontal portion of the inlet tube near the cap. The return area permits water that is blocked by the inner wall of the cap to flow upward into the discharge tube.          The garbage blocking member is fitted detachably in the intermediate section of the horizontal portion of the inlet tube under the discharge tube. Accordingly, water flows through  the garbage blocking member from the inlet tube to the discharge tube two times so as to hold garbage on the garbage blocking member for disposal.

Abstract: An improved, light-transmitting, plastic shelter cone or terrarium is provided for the germination of seed and growth of seedlings. The cone has a lower soil-engaging flange at its base and a vent opening at its top. The vent opening is covered with a hinged flap which is an integral part of the cone and to which seed may be secured using a water soluble adhesive. When placed in the field, the flap is pressed down into engagement with sidewall indentations which hold the flap and seed in a generally vertical orientation within the cone chamber. Stiffening ribs are formed in the cone wall, protruding outwardly and forming grooves within. Seed may be secured within a groove with water soluble adhesive. When the cone is used, rainfall will dissolve the adhesive, whereby the seed may drop to the soil below. Latching the flap ensures that it does not return to block the vent opening.          Preferably, the plastic is sunlight degradable and is further colored translucent red to modify the transmitted light.

Title: Agglomeration of oil/coal coprocessing feed coal using mixture of coprocessing product oil and heavy oil as bridging agent
Inventor: COLEMAN RICHARD D
IPC: C10G47/00
Filed: 1993-08-03
Abstract: Abstract An improved process is described for agglomerating ground coal in which a bridging oil is used as the agglomerating vehicle.  This bridging oil is a mixture of a heavy gas oil obtained from coal/oil coprocessing and a minor proportion of a heavy hydrocarbon oil, such as bitumen or heavy oil.  The agglomerated product is mixed with additional heavy oil or bitumen and it becomes the feedstock to a coal/oil coprocessor, with heavy gas oil being formed as one of the product streams.  At least part of this heavy gas oil product stream is recycled to the agglomeration stage as the heavy gas oil component of the bridging oil.  This agglomeration procedure has the advantage of providing an agglomerate of excellent quality, while carrying out the agglomeration in a short time at ambient temperature and using less than 10% by weight of bridging oil.

Title: Improved Deinking Method Using Ink Agglomeration
Inventor: MARKHAM LARRY D
IPC: B01D21/00
Filed: 1992-10-02
Abstract: Deinking of printed paper is accomplished by repulping printed wastepaper in an aqueous medium containing a deinking chemical. The presence of the deinking chemical causes initial agglomeration of ink particles to produce an ink pulp medium. Agglomerated ink particles are removed from the ink pulp medium by size and density separation procedures to separate coarse ink and produce a fine ink particle stream. The fine ink particle stream is recirculated to cause additional agglomeration of ink particles. The reagglomerated ink particles are removed from the fine ink particle stream by size and density separation procedures to produce a substantially ink free pulp medium. The invention provides agglomeration processes with high ink removal from printed paper.
