Title: Inhibitors of farnesyl-protein transferase
Inventor: CICCARONE TERRENCE M
IPC: C07D521/00
Filed: 1996-03-25
Abstract: The present invention comprises peptidomimetic compounds which comprise a suitab ly substituted aminoalkylbenzamide moiety. The instant compounds inhibit the farnesyl protein transferase enzyme and the fa rnesylation of certain proteins. Furthermore, the instant farnesyl protein transferase inhibitors differ from those previously described a s inhibitors of farnesyl-protein transferase in that they do not have a thiol moiety. The lack of the thiol offers unique advantages in terms of improved pharmacokinetic behavior in animals, prevention of thiol-dependent chemical reactions, such as rapid autoxidation and disulfide formation with endogenous thiols, and reduced systemic toxicity. Further contained in this invention are chemotherapeutic compositions containing these farnesyl transferase inhibitors and methods for their production.

Abstract: Des noyaux (12) polymères réticulés non conducteurs ayant une surface sulfonée échangeuse de cations sont soigneusement séparés en fractions de taille et de densité égales. Chaque fraction est plaquée séparément, de préférence avec un cation de cuivre, de palladium, de nickel, de titane ou de tout autre métal, qui se réduit avec de l'hydrazine pour former un revêtement métallique pelliculaire conducteur (14 ou 24). Les microsphères à placage pelliculaire sont à nouveau séparées en fractions de taille et de densité égales. Chaque fraction reçoit alors un placage métallique supplémentaire, d'abord de nickel (16 ou 26), ensuite de préférence de palladium (18 ou 28), puis une couche de support du palladium, suivie de préférence par une couche métallique stabilisatrice (32) telle que du chrome. Les microsphères ainsi plaquées (10 ou 22) présentent un placage d'épaisseur uniforme et présentent une superficie maximisée pour la quantité de métal plaqué, ce qui les rend particulièrement utiles en tant que catalyseurs ou dans des produits ou des processus électriques. Des microsphères pourvues d'un placage de palladium (18 ou 28) présentent une amélioration considérable de l'adsorption d'hydrogène à la fois quantitativement et pour ce qui est de la vitesse. Une couche interne de nickel (16 ou 26) entre le revêtement pelliculaire de cuivre (14 ou 24) et la couche de palladium (18 ou 28) et une couche externe de nickel (20 ou 30) sur la couche de palladium servent à stabiliser structuralement la couche de palladium pendant un cycle de production de chaleur, sans inhiber l'adsorption de l'hydrogène par ladite couche de palladium.

Filed: 1996-07-02
Abstract: Products with a wall (1) comprising at least one layer (11) of ferromagnetic material may be tested by magnetizing the layer using magnetizing means (30) to generate therein a remanent magnetization (H) parallel to the wall surface, then moving magnetic field sensors (2) along the wall and measuring, in the presence of the remanent magnetization (H) alone, the magnetic field adjacent to the product surface, whereby changes in the field measured along the wall indicate defects (22) in the layer of magnetic material. The method is particularly suitable for testing elongated products in which the layer to be tested is not on the surface.      Specifically, the method is suitable for testing pipelines or tubes for transporting petroleum.
Patent CA-2227689-A1 (CA)
Title: Improved simulated solid fuel element
Inventor: JAMIESON DONALD REGINALD
IPC: F24C3/00
Filed: 1998-01-20
Abstract: An improved fireplace assembly is described having a sheet metal burner and an associated set of simulated logs to create different sizes and shapes of flames, or flame patterns. The flame patterns generate hot exhaust gases which heat portions of the simulated logs to glow. The glowing appearance of these portions is enhanced by the use of filaments, whether in strands or in mat form. The filaments are attached to, embedded in, or wound about the visible face of the simulated solid fuel element. When heated sufficiently the filaments glow. The burner ports used in the assembly to generate suitably attractive flame displays may include large or non-circular apertures or slots having local reinforcement to resist deformation of those apertures.

Patent CA-2228190-A1 (CA)
Title: Programmed method of and apparatus for screening debris
Inventor: MEURER DOUGLAS LEE
IPC: E02B8/02
Filed: 1998-01-29
Abstract: A programmed bar screen cleaner removes debris from a screen positioned in a channel to prevent the flow of the debris to a liquid treatment. A rake has tines for engaging the screen to move the debris toward and past an upper end of the screen to remove the debris from the screen. Automatic and controllable raking operations are provided to handle the situation in which there is debris jammed in the screen.  The jammed debris resists the movement of the rake along the screen, which is sensed via rake motor overloaded, indicated by motor current in excess of a limit. The existence of a jammed rake causes positive release of the rake from the face of the bars, and further movement of the rake is controlled according to the nature of the problem which caused the jamming. If the rake jams during a raking stroke, the jam is sensed, and according to the nature of the problem, the rake may be positively removed from the face of the bars, and then either returned to an original position at the beginning of the stroke, or advanced in the direction of the original stroke and then returned to the face for completion of the stroke, or advanced in the direction of the original stroke, then returned to the face, and then moved toward the original position at the beginning of the stroke to remove the cause of the jamming from the face of the bars.

Title: Receiver for determining a position on the basis of satellite networks
Inventor: GUILLARD PATRICE
IPC: G01S1/00
Filed: 1996-10-15
Abstract: The invention relates to GPS and GLONASS satellite positioning receivers. A  novel receiver architecture is provided for receiving signals from and calculating a position using both GPS satellites and GLONASS satellites. Said architecture comprises a radio reception chain with an antenna (10), frequency conversion circuits (18), an ultra-high-rate analog-to-digital converter (38) for the GLONASS channel, and a signal processing circuit with a plurality of service-integrated channels for receiving both GPS and GLONASS signals. Said circuit (40) uses a programmable pseudo-random code generator and a phase servo loop using a local oscillator to produce a local translated carrier frequency. The oscillator is controlled in such a way that a starting frequency is set for satellite signal acquisition. The resulting receiver avoids dependence on one or other of the satellite networks as one network may be used should the other fail.
