Abstract: The piston has a top land (1) and a second land (3) between which a ring groove (2a) is formed. A chamfered surface (3a) at the upper peripheral edge of the second land (3) has a width (C₁) larger than that of a chamfered surface at the lower peripheral edge of the top land (1). A compression ring (2) having a butt-type ring gap is disposed in the groove (2a) to be slidably contacted with the cylinder wall. With this structure, the oil consumption is effectively suppressed in both a high pressure condition and a negative pressure condition of the combustion chamber.

Abstract: An expandable transluminal atherectomy catheter is disclosed having forwardly directed cutting means (24) on the end of a catheter (22) which can be introduced into the artery into the proximity of the stenosis along a guide wire (32). During insertion the cutting means (24) is collapsed by an outer sleeve (40) which can be retracted after insertion to permit the cutting means to expand to fill the artery. The catheter is then advanced into the stenosis to cut away the plaque which is flushed back down the catheter. To retract the catheter the sleeve (40) is advanced to collapse the cutting means prior to withdrawal of the catheter. Preferably the guide wire (32) is hollow and carries a balloon (34) at its distal end which can be inflated to block the artery downstream of the stenosis to prevent removed plaque flowing further down the artery.

Abstract: Les convertisseurs d'une installation haute tension de transmission en courant continu ou d'autres installations de convertisseurs nécessitent fréquemment des circuits de réglage pour plusieurs grandeurs de réglage. Un seul circuit de réglage détermine alors l'angle de retard à la commande, cependant que les autres circuits de réglage doivent être maintenus en attente, afin de relayer ce circuit de réglage lors de variations rapides de l'état de fonctionnement. Conformément à l'invention, les différences de réglage de toutes les grandeurs de réglage sont saisies et, pour chaque grandeur de réglage, les paramètres de réglage d'une structure de réglage pré-programmée de façon générale sont disponibles. Il n'existe toutefois qu'un seul régulateur à structure de régulation pré-programmée de façon générale. Ce régulateur est constamment opérationnel, mais n'agit qu'à une valeur minimale ou maximale des différences de réglage, et utilise à chaque fois les paramètres de réglage appartenant au circuit de réglage activé respectif.

Abstract: L'invention concerne un procédé et un moyen de production d'une force antigravitationnelle comprenant un moyen de production d'une source de matière ayant une courbure d'espace-temps opposée à celle d'un corps en gravitation, de sorte que les courbures opposées produisent des forces antigravitationnelles répulsives mutuellement, ainsi qu'un procédé et un moyen d'application d'une force sur la matière courbée de manière opposée provenant de la source, dans lesquelles dans le cas de la Terre, l'équilibre des forces résultantes produit un travail gravitationnel répulsif sur la matière courbée de manière opposée et le champ gravitationnel du corps en gravitation dans la première courbure positive d'espace-temps. La courbure opposée, ou négative de matière est produite selon une variété bidimensionnelle de courbure négative dérivée d'une nouvelle théorie atomique cohérente avec la mécanique de Newton, les équations de Maxwel, la théorie atomique, la Relativité Générale ainsi que les forces nucléaires faibles et fortes, ce qui permet le calcul de n'importe quelle matière, énergie, ou force exprimé en constantes fondamentales de nature. Selon l'invention, la variété d'espace-temps de courbure négative est une solution des équations et des conditions limites de la nouvelle théorie atomique comprenant, en partie, une équation d'ondes tridimensionnelles. La variété satisfait la condition limite que sa transformation de Fourier d'espace-temps ne contient aucune composante qui soit synchrone avec des ondes se déplaçant à la vitesse de la lumière, par conséquent, la variété est non radiative. Selon un mode de réalisation, la matière de courbure négative produite par la source se déplace à une vitesse constante à un équilibre des forces, afin de produire un travail utile contre le champ gravitationnel du corps en gravitation, pour constituer un appareil utile pour produire une lévitation et une propulsion. Selon un mode de réalisation, on transforme la force électromagnétique en force gravitationnelle, puis on la convertit en

Abstract: The invention concerns an air blower (20) including a centrifugal fan (220) which is driven by an electric motor (210). The blower (20) has a two-part blower housing (22, 24) comprising an upper housing (22) which encloses the motor (210) beneath the motor cap (230) and a lower housing (24). The centrifugal fan (220) is disposed in the chamber between the upper and lower housings (22, 24). The plenum (54) around the fan (220) leads to an outlet (161) from the blower (20). An intake shield (120) extends across and blocks undesired entrance of objects into the inlet opening (86) in the bottom (84) of the lower housing (24). The blower (20) may be seated on a lid (180) across an opening in it. An adapter (140) in the lid (180) receives the intake shield (120) and has its own air inlet (146) to the blower (20). The orientation of the blower (120) with respect to the lid (180) is rotatable. Cooperating flanges (132, 166) on the blower and the adapter hold the blower to thelid (180) at two rotative locations and a button latch arrangement (190) (Fig. 12) latches the blower (20) at each of the two arrangements. Between the two latched orientations, the blower (20) may be lifted free of the lid (180).
