Patent EP-0385851-A1 (EP)
Inventor: DELICH DAVID LEE
IPC: C01B32/55
Filed: 1990-02-27
Abstract: For producing and holding CO₂ snow, first and second cylindrical horns (4, 6) connected to an open ended vertical discharge duct (8) to form a generally Y-shaped continuous expansion chamber. First and second nozzles (34, 36) axially positioned at the tops of the snow horns have tangential fluid discharge passages (33..35) which are mutually oppositely oriented to produce oppositely oriented spiral flows of CO₂ snow within the snow horns. The two oppositely oriented spiral flows meet in a mixing region where their spiral components are cancelled, leaving only a vertical component of motion so that the snow is discharged through the vertical discharge duct by gravity. The discharged snow can be stored in a snow receiving container without blowing or wastage.

Filed: 1990-02-21
Abstract: Procédé pour produire une bande contenant de l'aluminium, pouvant être emboutie et étirée, et peu sujette à la formation de cornes. On introduit une bande contenant de l'aluminium, coulée en continu, dans une machine à fraiser à chaud de manière à en réduire l'épaisseur d'au moins 70 pour cent, la température de sortie de la bande étant abaissée. On laisse ensuite se cristalliser la bande de manière à obtenir des grains à texture recuite. Puis on soumet cette bande à un laminage à froid de manière à en réduire l'épaisseur d'au moins 30 pour cent. On recuit la bande laminée à froid à une température intermédiaire de recuit. Enfin, on soumet la bande à une seconde opération de laminage à froid destinée à en ajuster au mieux l'équilibre entre formation de cornes à 45° et limite d'élasticité.

Abstract: An electrosurgical instrument for use in combination with an endoscope for cutting tissue and cauterizing/coagulating the resulting wound area is described. The instrument comprises an elongated flexible tubular member having a proximal end, a distal end, and plural lumens extending therebetween. Affixed to the distal end of the tube is a bullet-shaped ceramic tip member 22 having a centrally-disposed longitudinal bore 26 passing through the side wall of the tip member. The ceramic exterior surface of the tip member is covered with a conductive layer 28 forming a first inactive electrode. An electrical conductor 44 joined to that electrode surface feeds back through a lumen of the tube to its proximal end where it may be coupled to an electrosurgical generator. Also running through a lumen in the tube is another conductor 32, 42 which can be made to project outwardly through the opening in the tip member. A hub 36 having a spring-loaded plunger is affixed to the proximal end of the tube with the plunger joined to the wire 32 so that when the plunger is depressed, the distal end 42 of the wire will project a short distance beyond the extremity of the tip member. By coupling this second conductor to an electrosurgical generator, it becomes the active electrode of a bipolar pair.

Abstract: An internal combustion engine comprises: a valve operating system (18) connected to a pair of intake valves (V I1 , V I2 ) and arranged mainly when in a low speed rotation region of the engine to open one of the intake valves (V I1 ) by only a small amount such that the one intake valve (V I1 ) is brought into a substantially inoperative state during a suction stroke; a fuel injection valve (55) capable of injecting fuel toward a pair of intake ports (8) independently corresponding to the intake valves (V I1 , V I2 ); and a control means (67) for controlling the operation of the fuel injection valve (55), the control means (67) being arranged to control the fuel injection valve (55), with a fuel injection completion time (ΘFE) determined within a suction stroke, when one of the intake valves (V I1 ) is in the substantially inoperative state. This ensures that when one of the intake valves (V I1 ) has been brought into its substantially inoperative state, the injection of fuel by the fuel injection valve (55) can be completed when in the suction stroke, so that the injected fuel can be sequentially introduced into a combustion chamber (5) in a condition of the other intake valve (V I2 ) being open, thereby achieving an axially stratified air charge to provide improved combustibility.

Inventor: SCHNEIDER EDWARD T
IPC: B25J9/14

Abstract: A pressure vessel (A) is defined by end walls (16) and side walls (18). In the interior, a plurality of fins (12) define an assembly of thin passages (10) that are filled with a material (26) that expands as it changes from a solid to a fluid state. The passages are thin, on the order of 0.01 inches such that heat is transferred relatively quickly into and out of the material. The passages communicate with a manifold area (14) to a piston bore (40) or other structure (B) for converting fluid pressure into mechanical movement. The piston bore holds a low durometer seal (44), a higher durometer seal (46), and a movable piston (42). To generate rotary motion, the piston and vessel assembly are mounted for rotation about an eccentrically placed member (68). As the pressure vessel goes through heating and cooling reservoirs, the pistons expand and contract causing rotation (FIGS. 4-6). In another application, at least two of the assemblies are interconnected by a heat pump (74) such that heat can be moved back and forth between the two. Additional heat pumps are provided for moving heat from the ambient air or other sources of heat to the pressure vessels (FIG. 7). The actuator is also used to control a two position valve (FIG. 9) and a three position valve (FIG. 10). A pair of actuator vessels (160, 162) are connected by a common heat transfer device (164) for causing differential movement between pistons (166, 168), (FIG. 12).
