Title: Methods of preparing substantially pure cannabinoids and cannabinoid acids from plant material
Inventor: FLOCKHART IAN RONALD
IPC: A61P27/06
Filed: 2003-09-23
Abstract: Methods of preparing substantially pure cannabinoids and cannabinoid acids, or products enriched in them, from plant material comprise obtaining an extract containing the cannabinoid or cannabinoid acid and subjecting it to a chromatographic step to produce a partially purified extract. The partially purified extract is dissolved in a first solvent, any insoluble material and the solvent are removed, the product thus obtained is dissolved in a second solvent and insoluble material and solvent are removed to obtain the substantially pure cannabinoid or cannabinoid acid or products enriched in the cannabinoid or cannabinoid acid. The first and second solvents are different. One solvent is substantially more polar than, and the other is substantially less polar than, the cannabinoid or cannabinoid acid to be purified. In particular, one solvent may be an alcohol, preferably methanol, and the other a C5-C12 alkane, preferably pentane. Substantially pure preparations of   W  9 tetrahydrocannabinolic acid, cannabidiolic acid,   W  <9> tetrahydrocannabinol,   W  <9> tetrahydrocannabivarin, cannabigerol and cannabicliromene are disclosed.

IPC: F41G7/30
Filed: 2003-05-08
Abstract: A system and method (32) for measuring line-of-sight angular rates for all-weather precision guidance of distributed projectiles (16) and a guidance system (10) based thereon. In accordance with the novel method (32) for measuring line-of-sight angular rates, first the range rates of the target (14) relative to at least two projectiles (16) is determined, as well as the position and velocity of each projectile (16). Then, the line-of sight angular rate of the target (14) relative to at least one projectile (16) is computed from the range rates, positions, and velocities. In the illustrative embodiment, the range rate of the target (14) relative to a projectile (16) is determined based on a monostatic target Doppler measurement, a monostatic projectile Doppler measurement, a bistatic Doppler measurement of the target (14) by the projectile (16), and the earner frequency of a data link (26) between the projectile and the shipboard system. The guidance system (10) of the present invention includes a monostatic radar (18) illuminating the target (14), bistatic receivers (44) aboard at least two projectiles (16) fired at the target (14), and a system (32) for determining line-of-sight angular rates to the target based on the monostatic measurements and the bistatic measurements from at least two projectiles. The guidance system (10) further includes a system (34) for computing guidance command signals for at least one projectile based on the line-of-sight angular rates, and a projectile steering unit (52) aboard at least one projectile for steering the projectile based on the guidance command signals.

Title: Electromagnetic MWD telemetry system incorporating a current sensing transformer
Inventor: WISLER MACMILLAN MORGAN
IPC: E21B47/12
Filed: 2004-07-06
Abstract: An electromagnetic telemetry system for transmitting data from a downhole assembly 10, which is operationally attached to a drill string 25, to a telemetry receiver system 30. The data are typically responses of one or more sensors 14 disposed within the downhole assembly. A downhole transmitter 12 induces a signal current 36 within the drill string 25 and this signal current is modulated to represent the transmitted data, the induced signal current is measured directly with the telemetry receiver system 30. The telemetry receiver system 30 includes a transformer, that surrounds the path of the current and an electromagnetic current receiver. The transformer preferably comprises a toroid that responds directly to the induced signal current. Output from the transformer is input to an electromagnetic current receiver located remotely from the downhole assembly and typically at the surface of the earth 22. Alternately, voltage resulting from the induced signal current can be measured with a rig voltage receiver and combined with the direct current measurements to enhance signal noise ratio.

Filed: 2004-09-17
Abstract: A method for imaging a sample wherein the surface of the sample is irradiated with a source of coherent, continuous THz radiation in the frequency range 25 GHz to 100 THz. The radiation is detected once it has been reflected by or transmitted though the sample. A secondary reference beam is also detected which has a phase related to that leaving the source. The detected radiation is analysed for a characteristic feature within the radiation, such as the maximum detected amplitude, so that any change in phase of the characteristic feature can be monitored to derive structural information about the sample as a function of depth from the surface of the sample.
