Abstract: A discharge apparatus for discharging materials from a container onto a field, the apparatus comprising a power discharge device disposed adjacent to a discharge outlet defined by the container, the arrangement being such that when the apparatus is being used to spread the materials onto the field, the materials move from the container through the outlet towards the discharge device. A motor is drivingly connected to the discharge device for rotating the discharge device. A sensor senses the power used by the motor and a control controls the rate at which the materials are spread. A programmable device associated with the sensor and the control regulates the control. The arrangement is such that the programmable device dependent on the sensor regulates the control for controlling the rate at which the materials are discharged so that when the container is moved across the field, the materials are discharged onto the field at a varying rate in order to optimize usage of the materials.

Title: System and method of automatic call barring in a radio telecommunications network
Inventor: ASSI GHASSAN
IPC: H04W12/06
Filed: 1997-04-18
Granted: 2006-08-15
Abstract: A system for reducing fraudulent use of a mobile telephone number in a radio telecommunications network. The system automatically bars call originations from the mobile telephone if the mobile telephone does not register with the network for a predetermined time period, or if the mobile telephone does not originate a call for a second predetermined time period. The system determines when a mobile telephone originates a call, measures a predetermined time period with a timing mechanism, and starts the timing mechanism when the mobile telephone originates a first call. The system then determines whether a second call originated from the mobile telephone during the predetermined time period and restarts the timing mechanism at the time that the mobile telephone originates a second call upon determining that the second call originated from the mobile telephone during the predetermined time period. The system reauthorizes the mobile telephone to originate calls in the network upon verification of a personal identification number entered by the subscriber.

Abstract: A three-dimensional ultrasound imaging system includes an ultrasound probe to direct ultrasound waves and to receive reflected ultrasound waves from a target volume of a subject under examination. The ultrasound probe is swept over the target volume and the reflected ultrasound waves are conveyed to a computer wherein successive two- dimensional images of the target volume are reconstructed fo form a three-dimensional image of the target volume. The three-dimensional image is displayed on the monitor of the computer. A user interface allows a user to manipulate the displayed image. Specifically, the entire displayed image may be rotated about an arbitrary axis, a surface of the displayed image may be translated to provide different cross-sectional views of the image and a selected surface of the displayed image tray be rotated about an arbitrary axis. All of these manipulations can be achieved via a single graphical input device such as a mouse connected to the computer.

Title: Roulement autolubrifiant
Inventor: PETIT DOMINIQUE
IPC: F16C33/20
Filed: 1998-07-11
Granted: 2002-10-29
Abstract: L'invention concerne un roulement autolubrifiant (110) fabriqué sous la forme d'un substrat métallique (112) et de plusieurs structures saillantes (113), formées intégralement avec ledit substrat et se présentant comme un prolongement orthogonal de celui-ci. Une couche de glissement ou de roulement en polymère fluoré (114) est posée sur le substrat; des structures saillantes sont enfoncées dans ledit substrat. Les structures saillantes servent à maintenir en place la couche de roulement afin de l'aider à ne pas glisser le long de la surface lorsque le roulement est sollicité. Cet ancrage dans le substrat permet d'utiliser une couche de roulement relativement épaisse; ainsi la tendance au fluage se trouve-t-elle relativement réduite. En variante, les structures saillantes permettent de créer un roulement possédant durant toute sa vie un coefficient de frottement relativement constant et une couche de roulement relativement mince, lesdites structures pouvant fonctionner comme des ponts thermiques et électriques pour assurer une conductivité thermique et électrique relativement élevée entre le substrat et l'article qu'il supporte, par exemple, un arbre en rotation. Les structures peuvent se trouver également en contact direct avec l'article qu'ils supportent, et ce afin d'empêcher le grattage. A cet égard, les roulements possèdent un coefficient de frottement relativement bas, une durée de vie plus longue et une meilleure résistance au fluage et aux contraintes mécaniques; en outre, ils conduisent la chaleur et l'électricité.

Abstract: This invention is of a composition comprised of a smectite clay modified with an organic chemical composition and a polymer. The composition consists of an organic chemical/smectite day intercalate that has been ion-exchanged and reacted and intercalated with one or more quarternary ammonium compounds and an anionic material and further blended into a polymer resin to make a nanocomposite composition. This material can be blended into a wide variety of polymers. This kind of system gives improved dispersion over conventional organoclays, intercalates or hybrid clays described in the literature, especially in non-polar resins. The defined organoclay has been found to be highly dispersible in a variety of polymers, whether polar or non-polar.
