Patent CA-2424356-A1 (CA)
Inventor: MULLER ADAM
IPC: B01D11/00
Filed: 2001-10-16
Abstract: The invention relates to a method for producing an extract from cannabis plant matter, containing tetrahydrocannabinol, cannabidiol and optionally the carboxylic acids thereof. According to said method, the dried plant matter is ground and subjected to a CO2 extraction and the primary extract obtained is separated. The inventive method permits .DELTA.8 or .DELTA.9 tetrahydrocannabinol to be selectively obtained both from industrial hemp and from drug-producing hemp, optionally after dissolving the primary extract in ethanol, separating undesirable waxes and removing the solvent under reduced pressure.
Patent CA-2425273-A1 (CA)
Inventor: MORGAN JOHN
IPC: E01B27/16
Filed: 2003-04-11
Abstract: A conversion device that is structured to be coupled to the rotating axle of a motor and to an output assembly. The output assembly has an elongated shaft with an axis extending generally perpendicular to the axis of the motor axle. The output assembly further is coupled to a frame to resist movement in an axial direction. The conversion device includes an eccentric hub having a disk with a sidewall extending from the perimeter thereby forming a recess and a yoke having a shaft and an attachment pin. The disk is coupled to the motor axle. The yoke shaft is disposed within the eccentric hub recess and the attachment pin is pivotally coupled to the output assembly. As the eccentric hub is rotated by the motor, the hub causes the yoke moves in a circular path. The circular path of the yoke has directional components that are parallel to the axis of the output assembly shaft and perpendicular to the axis of the output assembly shaft. The attachment pin allows the yoke to pivot in a direction parallel to the axis of the output assembly shaft. Thus, only the motion perpendicular to the axis of the output assembly shaft is transferred to the output assembly shaft. This motion is a reciprocal rotational motion about the axis of the output assembly shaft.

Abstract: The present invention provides methods and apparatus for cutting tubulars in a wellbore. In one aspect of the invention, a cutting tool having radially disposed rolling element cutter is provided for insertion into a wellbore to a predetermined depth where a tubular therearound will be cut into an upper and lower portion. The cutting tool is constructed and arranged to be rotated while the actuated cutters exert a force on the inside wall of the tubular, thereby severing the tubular therearound. In one aspect, the apparatus is run into the well on wireline which is capable of bearing the weight of the apparatus while supplying a source of electrical power to at least one downhole motor which operates at least one hydraulic pump. The hydraulic pump operates a slip assembly to fix the downhole apparatus within the wellbore prior to operation of the cutting tool. Thereafter, the pump operates a downhole motor to rotate the cutting tool while the cutters are actuated.

Inventor: VANAMBURG DARRYL M R
IPC: A63J5/12
Filed: 2003-07-09
Abstract: A levitation device for performing illusionary magic. Manually controlled by a three way valve switch concealed in the hand. Extending from the valve and running up the sleeve of the arm are three air lines in which the CO2 passes. One line is the supply line which comes from the CO2 tank that is strapped to the person's waist with a belt and straps, the secondary line or waste line provides for the release of air pressure as the person slowly descends to the ground. The third line leads down the side or back of the person into and down the pant leg eventually connecting to the shoe lift cylinder, which is custom fitted into the heel of the shoe. Activating the three way valve slowly increases the air pressure enabling the shoe cylinder piston shaft and platform to extend out from the heel bottom and downwards towards the ground, lifting the person four to six inches creating an illusionary floating like effect. With the slow release of gas pressure the person slowly descends to the ground.

Inventor: NOVIKOV LENNY M
IPC: H05B39/08
Filed: 2004-01-21
Abstract: A dimmer control system has a communication control loop that connects a master unit in series with a plurality of remote units, and it is superimposed in series on the dimmer load line so as to allow two-way communication between the master unit and remote units without affecting the operation of the load. Communications from the master to the remote units are encoded in loop current fluctuations, whereas communications from any remote to the master unit are encoded in loop voltage fluctuations. The master unit has a switched power supply, for use during normal LOAD ON operation, in tandem with a capacitive power supply, for use during LOAD OFF operation of the control units so as to minimize hum. The master unit power supply circuit provides an output rail voltage comprised of a reference voltage for the load superimposed with a control loop voltage for the voltage drop across the series-connected remote units. The master unit has a POWER OFF detection circuit and a non-volatile memory for storing system status information, so that when power is restored, the system can be restored to its former power level. The switch units are formed with a cover frame mounting a switch plate on a hinge axis allowing ON/OFF movement of an opposing side thereof. An array of LED light pipes is mounted in the switch plate aligned with the hinge axis, in order to minimize displacement of the light pipes during actuator movement.
