Abstract: A method and a device for controlling the movement of a combined alumina feeding and crust breaking chisel in an aluminum production cell, wherein the chisel is moved downwards and upwar ds by means of a pneumatic cylinder which is alternatively fed with pressurized air, wherein electrical contact between t he chisel and the melt is detected when the chisel reaches the melt, wherein it is monitored whether said electrical contact has been reached within a predetermined time interval, and if not, air at a second, high, pressure is fed to said first, and wherein air at hig h pressure is fed to the second side of the cylinder after said electrical contact has been established so as to quickly withdraw the chisel from the hot melt in order to minimize heat transfer from the melt to the cylinder.

Abstract: An optical beam path directing system has a field-flattening optically transmissive wedge installed in spatially dispersed beam paths upstream of the planar surface of a micro electro-mechanical switch (MEMS) or liquid crystal array. The parameters of the field-flattening wedge and its location in the diffracted beam paths are defined such that the wedge effectively rotates a 'best fit' planar surface approximation of the curvilinear focal plane of a concave reflector into coplanar coincidence with the optical signal-receiving surface of the MEMS. As a result, loss variation is essentially flat and minimized across the optical signal transmission band.

Patent CA-2400986-C (CA)
Inventor: ISRAELSSON MARIA
IPC: A01H5/00
Filed: 2001-03-02
Granted: 2007-07-03
Abstract: Important aims in nearly all tree-breeding programs around the world are to produce plants with increased growth rates and stem volumes, and shorter rotation times. Such trees would yield more biomass per area unit. Here the present inventors have shown that when over-expressing a key regulatory gene in the biosynthesis of the plant hormone gibberellin (GA) in hybrid aspen (Populus tremula x P. tremuloides), improvements in valuable traits such as growth rate and biomass are obtained. In addition, these trees also have longer xylem fibers than unmodified wild type plants.  Long fibres are very desirable in the production of strong paper, but it has not (as yet) proved possible to influence this trait by traditional breeding techniques. A further advantage of the present invention is that it may reduce or eliminate the use of growth influencing chemicals in forestry.

Granted: 2006-07-11
Abstract: A stationary exercising device which promotes cardiovascular exercise yet minimizes impact to critical joints. A base frame supports a pair of reciprocating members which are displaced in a horizontal direction parallel with the floor at one end yet reciprocate in a circular motion at the other end through a coupling system attached to the frame. Structure is included which permits each foot of the user to move in a generally elliptical path during the climbing exercise. This provides for more natural movement of the knee and ankle joints minimizing unnecessary stress on the joints yet permitting a cardiovascular workout. The device may include linkage to facilitate a corresponding upper body exercise involving movement of the arm in which case each hand of the user is displaced along an arc or a substantially elliptical path, again promoting a more natural movement of the ankle, knee, elbow and shoulder joints and permitting a cardiovascular workout.

Inventor: WENZEL WILLIAM R
IPC: E21B4/00
Filed: 2003-11-07
Granted: 2010-02-16
Abstract: An apparatus for controlling a downhole drilling motor assembly includes a tubular housing having an interior sidewall which defines an interior bore. A mandrel is rotatably mounted within the interior bore of the housing. The mandrel has an exterior surface. A hydraulic dampener assembly is disposed between the interior sidewall of the housing and the exterior surface of the mandrel. The hydraulic dampener assembly limits the rate of rotation of the mandrel within the housing, thereby providing a preset resistance to reactive torque. The described apparatus can also be used as a steering tool by the addition of a feature that selectively blocks the flow of hydraulic fluids through the hydraulic dampener, thereby locking the mandrel in a selected directional position.
