Patent CA-2308790-A1 (CA)
Inventor: SHURTLEFF EDWARD C
IPC: B01D3/32
Filed: 1998-10-23
Abstract: An apparatus and method for reclaiming a useful oil product, from waste oil provides an evaporation chamber in which waste oil is heated and vaporized, preferably at a temperature which causes some cracking of the oil. Hydrogen is injected into the vaporized oil, so to cause saturation of at least some of the olefins in the vaporized oil. The vaporized oil is then condensed and recovered as a useful oil product. The apparatus operates at substantially atmospheric pressure, or a pressure only slightly above atmospheric pressure. Hydrogenation of the vaporized oil stabilizes the recovered oil, and prevents formation of tars and other heavier hydrocarbons, which can cause difficulties in use of the recovered oil.

Title: Waste water treatment method and apparatus
Inventor: LAMBERT LAWRENCE
IPC: C02F1/467
Filed: 2000-05-19
Abstract: A method for separating contaminants from a aqueous source containing contaminants. In one embodiment, the method involves the use of a high powdered oxidant dissolved within the aqueous system. The gas is dissolved within a reservoir in the aqueous solution and the pressure within the reservoir is controllable. This allows maximum contact of the oxidizing dissolved gas with the contaminant material. Once oxidized, the outlet of the reservoir is adapted to permit hydraulic cavitation. The net effect of the cavitation is to induce a foam formation which foam transports a floc into a separate phase from the aqueous solution. In this manner, the process is effectively a dissolved oxidizing gas mass transfer process. In another embodiment, the process may be augmented by electrocoagulation. This involves the use of an electric cell which is disposed within the reservoir containing the oxidant material. By providing electrodes and exposing the electrodes to a source of current, the contaminants within the aqueous solution are either oxidized or otherwise degraded and this complements the oxidation by the dissolved gaseous oxidant. An apparatus is also disclosed to effect the methods set forth above.

Title: Method for in vitro amplification of circular dna
Inventor: RUFFNER DUANE E
IPC: C12Q1/6844
Filed: 1999-01-09
Abstract: A method for generating and amplifying closed circular DNA having a specific sequence in vitro in a cell-free system is disclosed. Prior to the invention of this method, closed circular DNA could only be amplified in vivo in appropriate host cells. The essence of the method is the inclusion of a thermostable DNA ligase in a PCR reaction. This procedure is referred to as ligation-during-amplification (LDA), in which the fully extended DNA strands are ligated by the DNA ligase and used as templates for subsequent amplification. Closed circular DNA having a specific sequence can be selectively amplified exponentially by the use of two sequence-specific primers in the LDA reaction. In addition, one or more site-specific mutations can be introduced into a closed circular DNA by the use of one or more mutagenic primers in the LDA reaction. Various thermostable DNA  polymerases and thermostable ligases can be used for LDA apmlification. Any primer position and orientation, either inward or outward, can be used in LDA amplification, as long as there is at least one primer complementary to each strand of the circular DNA. This method has applications in the areas of mutagenesis, cloning, DNA detection, DNA modification, genehunting, gene therapy, and cell-free DNA  production.

Filed: 2000-11-15
Abstract: During the cooling of high-temperature superconductor arrangements in which a polymer-composite-based electrically conducting transitional layer 3 is provided between a superconductor 1 and an electrical bypass 2, thermomechanical stresses occur in said transitional layer. To reduce these and to prevent the formation of cracks, the coefficient of thermal expansion of the transitional layer 3 is reduced. This takes place by adding a suitable filling material 32, for example particles of Si02, Al2O3 or AIN, to the polymer composite material.
