Title: Self-heating or self-cooling containers
Inventor: SEARLE MATTHEW JOHN
IPC: A47J36/28
Filed: 2000-10-16
Abstract: A self-heating container (10) has an internal cavity (22) for its contents a nd an external cavity (20) for a heating mechanism, for example, comprised of first and second chemically reactive materials which are arranged to be mixe d when heating is required. A protective cover (52) is engaged on the can over  the top end member (14) to prevent access to a ring-pull opener (50). The protective cover (52) has been shrunk onto the can such that it cannot be removed normally. However, when the can and its contents have been heated to  the predetermined temperature by operation of the heating mechanism, the protective cover (52) expands in size relative to the can (10) and is removable. The ring-pull opener (50) may then be opened to enable the conten ts to be dispensed. After opening, the cover (52) may be reengaged on the can t o provide an insulated drinking lip which protects the consumer against the he at of the can and provides a more pleasant surface to drink from than the edge of the can itself.

Title: Activation synergique d'elements regulateurs par des proteines rel et un recepteur de steroide
Inventor: BOERSMA CHRISTINE J C
IPC: C07K14/705
Filed: 2001-03-06
Abstract: L'interaction de protéines Rel et de récepteurs de stéroïdes est connue pour mener à la répression de gènes cibles. L'invention concerne un mécanisme dans lequel des protéines Rel et des récepteurs de stéroïdes agissent en synergie en activant un élément régulateur. On montre que ce mécanisme influence l'expression du récepteur 5HT1A spécifique du cerveau dans lequel le récepteur d'oestrogène agit en synergie avec le facteur nucléaire kappa B en augmentant l'activité du promoteur pour le gène du récepteur 5HT1A. En outre, on a observé des effets de synergie de protéines Rel avec le récepteur de minéralocorticoïdes, ce qui montre qu'une synergie avec des protéines Rel peut être attendue aussi bien avec des récepteurs d'autres stéroïdes. L'effet de synergie entre des protéines Rel et un récepteur d'oestrogène ou un récepteur de minéralocorticoïde constitue un outil pour le développement de composés qui interagissent avec le récepteur d'oestrogène ou de minéralocorticoïde d'une telle façon que seul l'effet de synergie est modulé alors que d'autres effets ne sont pas touchés. De tels composés sont inestimables pour le développement de médicaments destinés au traitement de maladies du système nerveux central ou du système cardio-vasculaire ainsi qu'au traitement d'autres troubles dans lesquels les protéines Rel jouent un rôle.

IPC: A61M60/822
Filed: 1998-10-23
Abstract: A blood pump for assisting a heart is provided having a stator and a rotor.  The rotor is magnetically radially supported creating a suspension gap between the stator and the rotor. The rotor can be supported axially by a Lorentz force bearing and can be magnetically rotated. The stator can have a single or double volute pump chamber and the rotor can have an impeller portion for pumping blood. The rotor can have a center bore as a primary blood flowpath. The suspension gap can be a secondary blood flowpath. The blood pump can also have an axial position controller and a flow rate controller. The axial position controller can cause the axial bearing to adjust the position of the rotor. The flow rate controller can have a member for measuring a dimension of a heart ventricle to control the flow rate to avoid overly distending or contracting the ventricle. A method of operating the flow rate controller to create a pulsatile flow rate is also provided. Additionally, the blood pump can be part of a cardiac assist and arrhythmia control system. Moreover, a method of operating the flow rate controller can be provided which reduces the amount of energy needed to treat fibrillation. The method can include operating the flow rate controller to reduce a radial dimension of the ventricle prior to delivering defibrillation energy such that the ventricle contains less blood which absorbs less energy so that a larger fraction of the energy is delivered to the heart.

Abstract: A solid fuel burner using a low oxygen concentration gas as a transporting gas of a low grade solid fuel such as brown coal or the like and a combustion method using the solid fuel burner are provided. The solid fuel burner comprises a means for accelerating ignition of the fuel and a means for preventing slugging caused by combustion ash from occurring. Mixing of fuel and air inside a fuel nozzle 11 is accelerated by that an additional air nozzle 12 and a separator 35 for separating a flow passage are arranged in the fuel nozzle 11, and the exit of the additional air nozzle 12 is set at a position so as to overlap with the separator 35 when seeing from a direction perpendicular to a burner axis, and additional air is ejected in a direction nearly perpendicular to a flow direction of a fuel jet flowing through the fuel nozzle 11. An amount of air from the additional air nozzle 12 is varied corresponding to a combustion load. By increasing the amount of air from the additional air nozzle 12 at a low load operation, an oxygen concentration of a circulation flow 19 formed in a downstream portion outside the exit of the fuel nozzle 11 is increased to stably burn the fuel. By decreasing the amount of air from the additional air nozzle 12 at a high load operation, a flame is formed at a position distant from the fuel nozzle 11 to suppress radiant heat received by structures of the solid fuel burner and walls of the furnace.
