Title: Electrically assisted partial oxidation of light hydrocarbons by oxygen
Inventor: CZERNICHOWSKI M ALBIN
IPC: C07C5/327
Filed: 1998-08-28
Abstract: The purpose of the process and device (1) to assist with gliding electric discharge plasma (4) the partial oxidation of hydrocarbons, accompanied by their steam reforming and/or reforming with CO2, is to produce gases rich in CO and H2 that may also have high contents of C2H4 and C2H2, without any formation of soot or coke. This mixture of products is achieved in a plasma reactor with gliding electric discharges (1) that glow in the compartment (15a) brought to a temperature lower than 1200 ° C and at a pressure of less than 6 bars.  The discharges act directly in an oxothermic reactive medium consisting of hydrocarbons mixed with gaseous oxygen of any origin, and possibly with H2O and/or CO2. The flow of products activated by the plasma and exiting the zone (15a) comes into contact with a metal or ceramic material (19) placed in the compartment (15b) that is brought to a temperature not exceeding 1100 °C. This material becomes active in the presence of the flow of products and, as such, it contributes to the enhancement of the conversion of the products exiting the plasma compartment (15a) into the final product.
Patent CA-2301086-A1 (CA)
Title: Animal feed containing carboxylic acids
Inventor: BAKER DAVID H
IPC: A23K1/175
Filed: 1998-07-01
Abstract: An animal feed containing a carboxylic acid either as the sole active ingredient or in combination with 1.alpha.-hydroxylated vitamin D compounds and/or phytase. The carboxylic acid or the combination of carboxylic acid with vitamin D compounds and/or phytase causes improved utilization of phosphorus, calcium, potassium, magnesium, zinc, iron and manganese in animal feed so as to minimize, or perhaps eliminate, the need for supplemental quantities of these minerals in an animal diet. In addition, low phosphorus containing animal feeds reduce the polluting effects on the environment since less phosphorus is excreted in the animal's feces which are then spread on agricultural land.

Title: Bi-centered drill bit having improved drilling stability, mud hydraulics and resistance to cutter damage
Inventor: TRUAX DAVID
IPC: E21B10/26
Filed: 2000-06-23
Abstract: A bi-center drill bit includes pilot and reaming blades affixed to a body at azimuthally spaced locations. The blades have PDC cutters attached at selected positions.  In one aspect, the pilot blades form a section having length along the bit axis less than about 80 percent of a diameter of the section. In another aspect, selected pilot blades and corresponding reaming blades are formed into single spiral structures. In another aspect, shapes and positions of the blades and inserts are selected so that lateral forces exerted by the reaming and the pilot sections are balanced as a single structure. Lateral forces are preferably balanced to within 10 percent of the total axial force on the bit. In another aspect, the center of mass of the bit is located less than about 2.5 percent of the diameter of the bit from the axis of rotation. In another aspect, jets are disposed in the reaming section oriented so that their axes are within about 30 degrees of normal to the axis of the bit. In another aspect, the reaming blades are shaped to conform to the radially least extensive, from the longitudinal axis, of a pass-through circle or a drill circle, so the cutters on the reaming blades drill at the drill diameter, without contact to the cutters on the reaming blades when the bit passes through an opening having about the pass-through diameter.
