Patent CA-2254346-A1 (CA)
Inventor: BOYTER RUBEN C
IPC: E21B7/06
Filed: 1997-05-09
Abstract: A sectional drive system for transmitting power linearly or in a curved path to an output, which system includes multiple tapered and splined, interlocking driving segments (17) which are nested and stacked as a segment string (10) that is rotatable in a guide path. The top one of the segments cooperates with a drive mechanism (12) to effect rotation of the nested segments in concert and the bottom one of the segments connects to a suitable output such as drill bit (42). Articulation of the segments with respect to each other due to matching asymmetrical splines (19) and companion spline slots (24) facilitates dampening of drive vibration and bending of the segment string in the guide path in any desired direction to facilitate transmitting power in a curved path of desired magnitude from the drive mechanism to the output. In a typical application the interlocking driving segments are incorporated in a downhole drilling apparatus designed for insertion in a well bore to facilitate drilling holes at selected angles in an uncased hole or through the well casing (7), cement sheath and producing interval to enhance well production.  The driving segments and bit will continue travelling in a straight line and continue on the same path presented when existing the guide path from the downhole drilling apparatus.

IPC: E05B11/00
Filed: 1999-01-07
Abstract: An apparatus having two barrel and tumbler locks which are longitudinally overlapped and conjoined to operate in combination with each other. When the first lock is moved to an open position it becomes frozen with the key snagged therein. The second lock is used to unfreeze and release the key from the first lock. Both locks are of the type having a barrel and tumbler. The first lock has a barrel having a ramped circumferential groove segment having a shallow end portion. A groove wafer extends from the tumbler into this groove. The second release lock has a circumferential groove segment in its barrel similarly having a groove wafer extending from the tumbler into this groove. The groove segments are arranged so that the shallow end portion of the first ramped groove segment meets an end portion of the groove on the second lock so that when the first lock is rotated from a closed position to an open position its groove wafer moves from the ramped groove downwardly into the groove segment in the second barrel, thereby preventing the barrel from being rotated back to an open position to release its key. The first lock may only be released when the groove wafer in the second lock is used to push the first groove wafer out of the groove segment in the second barrel.

Title: Control of microsporogenesis by externally inducible promoter sequences
Inventor: HUFFMAN GARY A
IPC: C12N15/82
Filed: 1991-05-13
Abstract: An inducible promoter is used to regulate expression of a gene which is known to be critical in microsporogenesis, i.e., the production of pollen. The selected gene's control sequences are modified so that it is normally "off" and as a result the plants are male sterile. When it is desired to reproduce the male sterile plants, male fertility is restored by treating the plants with a non-phytotoxic chemical which induces expression of the critical gene.

Title: Method of gasifying solid fuels in a circulating fluidized bed
Inventor: LOEFFLER JOHANNES
IPC: C10J3/84
Filed: 1997-12-01
Abstract: Combustible fuels, for example waste substances, biomass or coal, are gasified in a circulating fluidized bed with the addition of oxygenous gas at temperatures ranging from 700 to 1000 ~C. A fuel gas is obtained which contains dust and hydrocarbons, including higher hydrocarbons (C6+  hydrocarbons), and has a calorific value of between 2000 and 8000 kJ/m3. The dust-laden gas is passed through a separation chamber in which the higher hydrocarbons present in the gas are largely separated by the addition of gaseous oxygen at temperatures ranging from 800 to 1200 ~C and below the temperature of the ash melting point. The content of C6+ hydrocarbons present in the gas emerging from the separation chamber is at most 10 wt % of the initial content. The gas from the separation chamber is cooled and dedusted and passed through at least one bed or at least one reactor with granular solids which bind with pollutants. The gas-purification process is carried out without forming waste water.

IPC: B65D83/58
Filed: 1998-10-07
Abstract: A dispensing apparatus for dispensing a product from a container under pressure of a propellant by means of a composite piston (138). The apparatus has a valve (104) operated by means of an actuator (108) and a lever (166).  The actuator cooperates with the valve and lever by means of a screw thread arrangement (110), such that turning actuator relative to the lever varies the flow rate of product out of the apparatus. The valve is a hollow cylindrical tube (104) which is open at one end and closed at the second end, either permanently or by means of a flap valve (112) which allows insertion of the product. A number of ports (116) are arranged around the circumference of the tube (104) adjacent to the second end to allow product to flow through the valve when the lever is operated. The composite piston (138) comprises a first piston (140a) coupled to a second piston ( 140b) by mutually engageable central stems (142a, b) and enclosing between the pistons a viscous substance which contacts the inside wall of the container to provide an effective seal. The piston arrangement of the apparatus stays together without the need for "necking in" the can and the apparatus can be filled with product by the manufacturer.
