Patent EP-0805295-A1 (EP)
Inventor: KHADIM NEIL M
IPC: F02M21/06
Filed: 1997-04-30
Abstract: The invention relates to an "instant-on" valve assembly incorporating a manual override, designed to be connected to a tank containing high pressure gaseous fuel, for example for use in a gas powered vehicle. The valve assembly and manual override allows the tank to be alternately closed off, vented, or allows the gas in the tank to bypass the instant-on valve. The instant-on valve assembly can be repaired or replaced without venting the tank. 
     The instant-on valve assembly (8) has a main valve (16, 18) and a bleed valve. The main valve has a primary plunger (16), and a secondary piston (18) that opens and closes a main orifice (40). The bleed valve has a bleed valve stem (52) that opens and closes a bleed orifice (50) and is connected to the primary plunger (16). The main valve (16, 18) is slidably mounted within a housing (20, 32) and has a chamber (38) at one end and a zone (76) at another end. Both the zone (76) and the chamber (38) have access to high pressure gaseous fuel within the tank when the main and bleed valves are closed. High pressure gaseous fluid within the zone (76) can be drained when the bleed valve is fully open. Activation of a solenoid (24) displaces the primary plunger (16) which in turn displaces the bleed valve stem (52) to open the bleed valve. When the pressure within the zone (76) is sufficiently reduced, the pressure within the chamber (38) will cause the main valve to open by sliding into the zone. A spring (66) moves the main valve towards a closed position when the solenoid (24) is deactivated. Since the volume of the zone (76) is relatively small, the main valve opens within one second after the solenoid is activated.

Abstract: A method and apparatus for defining a system design specification by using a
finite set of templates that have a format for accepting a set of system expression such
that a selected template, when filled with the system expressions, defines an expected
behavioral attribute of the system. In one illustrative embodiment, each template has a
set of qualifiers and a set of entry blanks, wherein each qualifier is associated with an
entry blank. In such an embodiment, the set of entry spaces may comprise a fulfilling
condition entry space for accepting a system expression that defines a required or
assumed event of the system model, an enabling condition entry space for accepting a
system expression that defines a precondition for starting a check of the required or
assumed event, and a discharging condition entry space for accepting a system
expression that defines a condition after which said fulfilling condition is no longer
required or assumed by the system model. Filling the entry spaces of a selected
template with the appropriate system expression can form an expression that defines an
expected behavior of the system model. Thus, a set of filled templates can define a set
of expected behaviors of the system model (i.e. a system design specification). The
system design specification can then be used to generate computer-executable code (e.g.
automata) for testing the expected behavioral attributes of the system. For example,
each filled template of the system design specification can be converted to an automaton
by a given subroutine.

Abstract: The assembly takes place with the aid of an adapter (D) placed between a tool (1) and an actuator (2). The adapter has two parts (3,4) that slide one relative to the other along a longitudinal axis between an extended position and a closed position. A spring (7) is placed between these two parts of the adapter and tends to keep the two parts in the extended position. A detector (11) fitted to the adapter delivers a bi-state signal depending whether the adapter is opened or closed, and a second detector (18) fitted to the adapter measures its position relative to the required end of travel position. The two signals are used to confirm correct assembly.

Abstract: L'invention concerne un procédé simplifié pour mettre en évidence des différences dans l'abondance d'acides nucléiques (par exemple de niveaux de leur expression) entre deux échantillons ou davantage. Le procédé consiste à préparer un système contenant un grand nombre (par exemple supérieur à 1000) de sondes oligonucléotidiques différentes choisies arbitrairement, où la séquence et l'emplacement de chaque sonde sont connus. Les échantillons d'acide nucléique (par exemple d'ARNm) de deux échantillons ou davantage sont soumis à une hybridation avec les sondes du système et le motif d'hybridation est déterminé. Les différences dans les motifs d'hybridation entre les échantillons indiquent des différences dans l'expression des diffèrents gènes, entre ces échantillons. L'invention concerne également un procédé pour marquer l'extrémité d'un acide nucléique. Dans une forme d'exécution, le procédé consiste à choisir un acide nucléique et un oligonucléotide marqué et ensuite à lier l'oligonucléotide à l'acide nucléique par voie enzymatique. Ainsi, par exemple, quand l'acide nucléique est un ARN, on peut lier l'oligonucléotide marqué en utilisant une ARN-ligase. Dans une autre forme d'exécution, le marquage terminal peut se faire en choisissant un acide nucléique et des nucléosides triphosphates marqués et en liant les nucléosides triphosphates à l'acide nucléique à l'aide d'une transférase terminale

Abstract: A single cell, multi-electrode high performance double layer capacitor includes first and second flat stacks of electrodes adapted to be housed in a closeable two-part capacitor case which includes only a single electrolyte seal. Each electrode stack has a plurality of electrodes connected in parallel, with the electrodes of one stack being interleaved with the electrodes of the other stack to form an interleaved stack, and with the electrodes of each stack being electrically connected to respective capacitor terminals. A porous separator sleeve is inserted over the electrodes of one stack before interleaving to prevent electrical shorts between the electrodes. The electrodes are made by folding a compressible, low resistance, aluminum-impregnated carbon cloth, made from activated carbon fibers, around a current collector foil, with a tab of the foils of each electrode of each stack being connected in parallel and connected to the respective capacitor terminal. The height of the interleaved stack is somewhat greater than the inside height of the closed capacitor case, thereby requiring compression of the interleaved electrode stack when placed inside of the case, and thereby maintaining the interleaved electrode stack under modest constant pressure. The closed capacitor case is filled with an electrolytic solution and sealed. A preferred electrolytic solution is made by dissolving an appropriate salt into acetonitrile (CH3CN). In one embodiment, the two parts of the capacitor case are conductive and function as the capacitor terminals.
