Title: Fuel injector with a silicon nozzle
Inventor: GARDNER ROBERT C
IPC: F02M61/18
Filed: 1992-02-19
Abstract: Abstract of the Invention A fuel injector for use in an internal combustion engine is provided and comprises an injector body having a first portion with an inlet for communicating with a fuel source, a second portion having an outlet for ejecting fuel from the body, and an inner passageway which communicates with the inlet and the outlet.  A fuel valve is located within the inner passageway for controlling fuel ejection from the outlet.  A silicon nozzle is positioned adjacent to the second portion for metering and dispersing fuel as it is ejected from the outlet.  A retainer is connected to the injector body for retaining the nozzle against the second portion.  The retainer includes a side portion and a base portion extending at an angle relative to the side portion for applying a spring-biased force against the nozzle to retain the nozzle against the second portion, thereby substantially sealing the interface between the nozzle and the second portion from fuel leakage.

Title: Antibodies to complexes of ligand receptors and ligands and their utility in ligand-receptor assays
Inventor: BUECHLER KENNETH F
IPC: G01N33/541
Filed: 1991-09-04
Abstract: Methods and test devices for detecting the presence or amount of target ligand in non-competitive sandwich ligand-receptor assay processes. Antibodies which bind to the complex of ligand receptor and target ligand but do not bind significantly to the ligand receptor and which bind the target ligand with substantially less affinity than the complex are taught and their uses described.  These assays can be used to eliminate the "hook" effect in non-competitive sandwich assays. Furthermore, the antibodies are selected and assay methods described so that, as a result of the assay process, no detectable response is observed due to the binding of antibody and ligand receptor in the absence of target ligand.

Title: Circuit breaker with protection against sputtering arc faults
Inventor: MACKENZIE RAYMOND W
IPC: H02H1/00
Filed: 1992-09-25
Abstract: A circuit breaker includes an electronic trip device which responds to sputtering arc-type faults. Level detectors compare the current in the protected circuit to a plurality of threshold levels and timers time the intervals that the current remains above each threshold, with the threshold levels and intervals selected to generate a response envelope for a trip signal which approximates, with a selected margin, the response of the protected circuit to introduction of a selected inductive load such as the starting of a motor into the circuit. If the sensed current falls below a threshold level which was being timed, the associated timer is not cleared unless the current falls below the lowest threshold, so that if the sensed current increases above the associated thresholds timing resumes where it left off, and a trip signal wall be generated sooner than for an initial excursion above the threshold.      Both analog and digital timer implementations are presented.

Title: Improved system and method for jacketing cross-domain calls in a multi-code execution and debugging system within a multi-architecture environment
Inventor: ILES MICHAEL V
IPC: G06F11/28
Filed: 1992-03-05
Abstract: A cross-domain call jacketing system is provided in a computer system that embodies a first hardware (X) architecture to executing X-code in an X-domain and which simulates at least a second computer hardware (Y) architecture executing Y-code in a Y-domain. Cross-domain routine calls are jacketed for services in the cross-domain and for returns after the requested services have been performed. After jacketing X routine calls are transmitted for implementation by the simulating subsystem and Y calls are transmitted for implementation in the X domain. Call parameters are transformed from a representation that uses the call conventions of the calling domain to another representation that uses the call conventions of the called domain. Data in the mem-ory is generally globally accessible and the Y calls include data references that require memory access handling in the X domain. A first jacketing table is provided for each executable routine in the X domain. A second jacketing table is provided for each ex-ecutable routine in the Y domain. A run-time jacketing routine is driven by the jacketing tables to drive the call parameter trans-formations needed to complete cross-domain calls.

Title: Method and system for setting the hydraulic pressure influencing a grab member
Inventor: KOLARI PEKKA
IPC: B66F9/18
Filed: 1991-07-01
Abstract: The object of the invention is a method and a system for setting the hydraulic pressure influencing a hydraulic grab member by using adjustment members. The setting of the maximum value of the pressure takes place automatically by reading the identifying information on the piece (6) being handled by means of a reading device (1), on the basis of which the control unit (3) linked to the reading device (1) directs the adjustment member (4). When the operator of the system starts raising the hydraulic pressure from the hydraulic tank (13) by means of the operating valve (9) of the grab member (5), the adjustment member (4) limits the hydraulic pressure going to the compression cylinder (8) of the grab member (5) and thus a compressive force of the correct magnitude is directed onto the piece (6) being handled.

Abstract: D E D I V U L G A T I O N L'invention concerne un train d'atterrissage relevable, avec caisson d'amortisseur et tige coulissante. Conformément à l'invention, le train d'atterrissage comporte une balancine latérale articulée sur le caisson et équipée d'une roue à son extrémité libre, ainsi que des moyens mécaniques d'accouplement associés à cette balancine latérale , de telle façon que d'une part la descente du train déploie la balancine latérale pour que sa roue complète en position train bas les roues du train de roues et constitue en plus un stabilisateur latéral lors du roulage de l'avion, et que d'autre part le relevage du train replie la balancine latérale pour permettre un logement d'ensemble en position train haut. Il devient dès lors possible d'agencer le train d'atterrissage sous le fuselage de l'avion, ce qui permet d'obtenir des trains extrêmement courts. Figure 1.

Inventor: LEVESQUE JACQUES
IPC: F23G5/08
Filed: 1993-03-04
Abstract: FORMULE 24 (Art. 21, 31, 34 et 142) Dans une chambre d'incinération de déchets, on sait que la torche au plasma est placée sur l'un des côtés de la chambre d'incinération suivant un angle d'élévation de plus ou moins 45.degree.. La chambre d'incinération se retrouve rapidement obstruée par les résidus de déchets qui ne sont pas tout à fait éliminés. Ce qui provoque également l'obstruction de l'ouverture de la chambre d'incinération. Dans la présente invention la torche au plasma est placée à la base de la chambre d'incinération de déchets. Un tel positionnement permet d'utiliser la force de la gravité afin de permettre l'élimination totale des déchets devant faire l'objet de la combustion. Le déchet à être éliminé se trouve ainsi en tout temps très près de la torche et de l'emplacement où la chaleur est la plus élevée. L'effet de pression des gaz de plasma dégagé par la torche permet ainsi d'éviter toute obstruction de la chambre d'incinération. L'utilisation d'air comprimé lors du refroidissement de la torche assure qu'en tout temps l'ouverture demeure dégagée.

IPC: A61F2/90
Filed: 1991-11-22
Abstract: A stent (10) for transluminal implantation comprising a single-piece tubular member (12) having a fenestrated sidewall (18) exhibiting a pattern of uniformly spaced openings defined by intersecting strands (20, 22) where the strands (20, 22) are in-tegrally joined together at their points of intersection whereby the tubular member (12) can be radially compressed from a larger diameter to a smaller diameter by the application of a uniform inwardly directed radial force and which self-expands to a larger diameter when the radial compressive force is removed. The compression and subsequent self-expansion occurs without an ap-?reciable change in the stent's length. By forming the stent (10) from a thermoplastic material, it may later be resected by carving ?up into small pieces preferably using an electrosurgical instrument.
