Patent CA-2348773-A1 (CA)
Inventor: RAYHORN PAUL
IPC: C07K17/08
Filed: 1999-11-02
Abstract: L'invention concerne des variants de la protéine hedgehog comportant des modifications N-terminales, capables de bloquer la fonction hedgehog, ce qui leur permet ainsi de jouer un rôle d'antagonistes fonctionnels. Ces peptides comportent une séquence primaire d'acides aminés ne pouvant pas éliciter une réponse dépendant du hedgehog dans les cellules C3H 10T1/2, mais pouvant néanmoins se lier au récepteur hedgehog, patched-1. Sont également décrites des techniques de production de ces antagonistes fonctionnels et des techniques concernant leur utilisation.

Patent CA-2363878-A1 (CA)
Title: System and method for monitoring corrosion in oilfield wells and pipelines utilizing time-domain-reflectometry
Inventor: KOHL KRISTOPHER T
IPC: E21B47/00
Filed: 2000-03-08
Abstract: The present invention provides a system and method for in-situ monitoring of corrosion in a conduit which carries fluids that have corrosive effects on the materials utilized for the conduit and/or equipment disposed in the conduit. The conduit may include a well carrying hydrocarbons from subsurface formation or a pipeline transporting hydrocarbon. A cable of sufficient lenght having a conductor that is susceptible to the corrosive effects of the fluids in the conduit is deployed along a lenght of the conduit. The conductor is exposed to the fluid continuously or at selected spaced apart locations. The distance of each of the exposed locations from an accessible end is known. A signal generator coupled to the cable induces a pulsed signal into the cable. The transmitted signals are reflected by location on the cable where the impedance differs from the normal impedance. Such locations include each of the exposed conductor locations and the termination point.     The reflected signals are received by a receiver and then processed and analyzed by a processor to determine the extent of the corrosion at each of the exposed locations.     This information is then used to estimate the nature and extent of the corrosion of components in the wellbore or the pipeline, as the case may be. The cable may be a single conductor cable or a twisted pair of wires, each having a known impedance per unit length.

Filed: 2000-08-24
Abstract: This invention provides a method for enhancing the growth of acid-fast microorganisms in culture comprising growing the acid-fast microorganisms in the presence of an aliphatic organic acid of 8-10 carbon atoms. The diagnosis of tuberculosis and many other mycobacterial diseases has been hampered by the slow growth of these organisms using currently available culture methods. The addition of octanoic acid to currently available agar and broth media formulations utilized for the cultivation of pathogenic mycobacteria results in a marked reduction in generation time with an increase in growth yield. The growth promoting activity of octanoic acid offers the potential for significantly more rapid diagnosis, and treatment of these diseases.

Title: Aircraft spiralling mechanism - 2
Inventor: KUSIC TOM
IPC: B64C9/00
Filed: 2002-06-19
Abstract: An aircraft 1 in the form of an aeroplane with a spiral inducing assembly 2 which is capable of inducing the aeroplane to travel in a continuous spiralling motion without rolling. Two fins 3 and 4 are attached to a tube 5 that is able to rotate around the encircled part of the fuselage. The fins 3, 4 are able to rotate in a pivoting manner on the rotatable tube 5 with respect to the rotatable tube 5, thereby changing their pitch relative to the longitudinal axis of the rotatable tube 5. Fin 3 is larger than fin 4. The diferene in sizes between the fins makes the larger fin 3 exert a greater force on the rotatable tube 4 than the smaller fin 4 when the fins are pitched in unison. The aerodynamic imbalance between the fins thus casues the rotatable tube 5 to rotate. When pitched at an angle to the longitudinal axis in unison, both fins 3, 4 would exert a lateral force on the rotatable tube 5. Thus, as well as forcing the rotatable tube 5 to rotate, the fins 3, 4 would also push the rotatable tube sideways. But as the rotatable tube is pushed sideways, it rotates, and hence the lateral direction of push constantly revolves, causing a spiralling motion when in flight.

Abstract: The present invention relates to an apparatus and a process to extract heat and to solidify molten material particles.  A flow of molten material is traversed by a high pressure dispers-ing/cooling flow to form particles of molten or semi-molten ma-terial. The particles impinge against a transporting device, which transport them to a collecting place. The transporting device is provided with a vibrator, which provides a vibrating movement to the transporting device to prevent the particles which are still cool-ing-off from being agglomerated again. A flow of a low pressure dispersing/cooling could be provided, which substantially trans-versely traverses said flow of particles of molten or semi-molten material which fall towards the transporting device, in order to en-hance the dispersion and cooling-off effects of the particles. A  hopper could be provided to collect the particles and to carry them to the transporting device. Cooling water pipes could be provided to eject a flow of cooling water onto the internal walls of the hop-per and also onto the transporting device, which assist cooling of the dispersed particles.
