Abstract: Un procédé permet de protéger contre le vol des bateaux, notamment des yachts à voile et à moteur mouillés dans une zone délimitée dans l'espace, par exemple un port. On utilise à cet effet une unité fixe d'émission/réception et une unité d'émission/réception située sur le bateau. L'unité d'émission/réception située sur le bateau émet un signal d'identification propre au bateau lorsqu'elle est interrogée par l'unité fixe d'émission/réception. Afin d'obtenir un procédé efficace de protection de bateaux contre des utilisations illicites, le signal d'identification contient une caractéristique de base d'identification du bateau et les signaux d'identification de tous les bateaux mouillés dans le port sont enregistrés dans un ordinateur central. Afin de légitimer l'utilisation d'un bateau, on fournit avant le départ un code de légitimation à l'ordinateur central. L'ordinateur central vérifie si l'utilisation du bateau est légitime sur la base de l'interrogation effectuée par l'unité fixe d'émission/réception et déclenche le cas échéant un programme d'alarme et d'information.

Title: Servo-driven mud pulser
Inventor: FRITH TERRENCE G
IPC: E21B47/24
Filed: 1997-01-22
Abstract: An improved servo-driven pulser is disclosed, for use in measurement while drilling applications. In the pulser, a battery powered on-board DC electric motor is used to operate a servo-valve, which in turn adjusts internal tool fluid pressures to cause operation of a main valve to substantially reduce mud flow to a drill bit, thereby creating a positive pressure pulse detectable at the surface. De-energizing the motor driving the pilot valve results in re-adjustment of internal fluid pressures, causing the main valve to reopen, thereby terminating the pressure pulse.

Title: Factors and methods for reducing biological activity of a multimeric protein and methods of screening therefor
Inventor: RIOPELLE RICHARD J
IPC: C12N5/08
Filed: 1997-05-09
Abstract: Factors and methods for disrupting or inhibiting the association of protomers of a multimeric protein are described. Such inhibition reduces the biological activity of the target protein, which is desirable in the case of certain physiological disorders. Particularly, novel neurotrophin antagonists are described. In one aspect of the invention, peptides that inhibit the association of protomers of a growth factor having a cysteine knot, such as a neurotrophin, aredescribed. In another aspect, the antagonist is bicyclic peptide preferably derived from the internal reverse turn region of a member of the structurally similar neurotrophin family including NGF, BDNF, NT-3, NT-4/5 and NT-6 and functional equivalents thereof. Generally, the antagonist comprises amino acids from positions 68-58 and 108-110 of a neurotrophin, in which the amino acid from position 68 is covalently bound to the amino acid from position 108 and theamino acid from position 58 is covalently bound to the amino acid at position 110 to form a bicyclic structure. In another aspect of the invention transition metal ions are provided for selectively altering the geometry of the receptor binding domains of neurotrophins which allows functionality and activity of the neurotrophins to be selectively reduced. For example Zn2+ alters the conformation of NGF rendering it unable to bind to p75NTR or TrkA receptors or to activate signal transduction and biological outcomes normally induced by thisprotein. Molecular modelling studies predict that Zn2+ binding to NGF will induce structural changes within domains of this neurotrophin which participate in the recognition of TrkA and p75NTR N. Ni2+ on the other hand selectively alters the conformation of NGF rendering it unable to bind to TrkA but does not affect binding to p75NTR Similar actions of Zn2+ are also observed with other members of the NGF family, suggesting a modulatory role for the metal ions in neurotrophin function.
