Granted: 2000-11-28
Abstract: L'invention concerne un dispositif permettant de centrer un coussinet (4) constitué d'un matériau sensible aux contraintes de traction, tel que la céramique, sur un arbre (1) présentant à basse température de service un jeu par rapport au coussinet (4). L'invention vise à assurer un centrage correct du coussinet (4), même sur une plage de température élevée. A cet effet, au moins une bague de centrage (5), constituée d'un matériau non sensible aux contraintes de traction par rapport à l'arbre (1), est solidaire de l'arbre (1) sans jeu. Cette bague de centrage (5) agit de l'extérieur sur le coussinet (4) afin d'assurer le centrage de ce dernier. Il est prévu, de façon appropriée, de placer deux bagues de centrage (5) sur la face du coussinet (4). Afin qu'une dilatation thermique n'affecte pas l'entraînement en rotation du coussinet (4) par un blocage entre les bagues de centrage (5), la dilatation thermique des pièces (5, 6) du côté du coussinet doit être pratiquement égale à celle de la partie de l'arbre correspondante.

Granted: 2003-02-18
Abstract: A method of measuring the density of an earth formation penetrated by a wellbore. The method includes irradiating the earth formation with gamma rays from a source, detecting Compton scattered gamma rays at a plurality of locations spaced apart from the source along the wellbore, calculating an apparent density of the formation from the detected gamma counting rate at each of the locations, calculating differences in apparent density between pairs of the apparent densities, calculating a correction for the apparent density from a distal one of the locations by scaling the differences in apparent density according to an empirical relationship, and calculating the density by combining the correction with the apparent density from the distal one of the locations. In a preferred embodiment, the empirical relationship is determined by measuring the apparent densities and differences in apparent density at a plurality of known values of density of the formation and a plurality of values of density and thickness of a medium interposed between the formation, and the source and the spaced apart locations. Scaling coefficients are determined by minimizing the value of an error function representing the difference between the known value of the density and the density determined according to the empirical relationship.

Title: Marking and screening telephone calls
Inventor: HOLIDAY MATTHEW R II
IPC: H04M3/436
Filed: 1998-12-09
Granted: 2008-10-21
Abstract: A system and method that controls calls, such as telephone solicitations, by a calling party to a called party. A switch receives a call from the calling party and marks the call to identify it as a telephone solicitation. Such marking can be performed in various ways, such as altering a forward call indicator of an IAM message if the switch is using an ISUP procedure, or providing a station type with information digits used in multi-frequency signaling. After the call has been marked, it can then be identified by a switch serving the called party as a telephone solicitation. Once identified, the switch then analyzes a profile for the called party and determines how to complete the call. For example, if the profile indicates that the called party does not want to receive telephone solicitations, the call will not be completed to the called party, but instead will receive alternate treatment.

Title: Methods for the production of protein particles useful for delivery of pharmacological agents
Inventor: MAGDASSI SHLOMO
IPC: A61K9/14
Filed: 1997-08-19
Granted: 2010-03-30
Abstract: A method has been developed for the formation of submicron particles (nanoparticles) by heat-denaturation of proteins (such as human serum albumin) in the presence of multivalent ions (such as calcium). Also provided are novel products produced by the invention method.  An appropriate concentration of multivalent ions, within a relatively narrow range of concentrations, induces the precipitation of protein in the form of colloidal particles, at a temperature which is well below the heat denaturation temperature of the protein (as low as 60 °C for serum albumin). Temperatures at which invention method operates are sufficiently low to permit incorporation of other molecules (e.g., by co-precipitation), into submicron particles according to the invention, including compounds which cannot withstand high temperatures.  Invention methods facilitate the production of protein nanoparticles and microparticles containing various molecules (such as nucleic acids, oligonucleotides, polynucleotides, DNA, RNA, polysaccharides, ribozymes, pharmacologically active compounds, and the like) useful for therapeutic, diagnostic and other purposes. The addition of multivalent cations serves both to induce precipitation, and to allow linking of negatively charged molecules, such as DNA, to the negatively charged protein.

Abstract: A dielectric-loaded loop antenna for operation at frequencies above 200 MHz has an elongate cylindrical core with a relative dielectric constant greater than 5, a pair of co-extensive helical antenna elements, a coaxial feeder structure extending through the core from a proximal end to a distal end where it is coupled to the antenna elements, and a balum formed on the core cylindrical surface and connected to the feeder structure at the proximal end of the core. Each helical antenna element is bifurcated at an intermediate position so that proximally, it is formed of two generally parallel branches each of which is coupled to a respective linking path around the core to meet a corresponding branch of the other elongate element therefore forming a conductive loop between the two conductors of the feeder structure. The two conductive loops have different electrical lengths as a result of, for example, the branches being of differents lengths. In a preferred embodiment, the linking paths around the core are formed by the rim of a split conductive sleeve constituting the balum. The sleeve is formed in two parts separated by a pair of longitudinally extending diametrically opposed quarter wave slits each of which extends from the space between the branches of a respective helical antenna element to a short circuited end adjacent the proximal end of the core.
