Title: Methode et dispositif pour le reglage automatique de l'allumage d'un moteur a allumage commande
Inventor: DOUAUD ANDRE
IPC: F02P3/04

Abstract: ` L'invention concerne un dispositif et une méthode pour régler automatiquement l'allumage d'un moteur à allumage commandé à sa valeur optimale correspondant à la puissance maximale et au rendement maximal du moteur, dans laquelle ce réglage est modifié pour que le maximum de pression dans l'un au moins des cylindres du moteur apparaisse pour une position augulaire déterminée de l'arbre moteur.  On détecte les accélérations auxquelles la culasse au moteur est soumise et on délivre un premier signal représentatif de ces accélérations.  On intègre ensuite ce signal de mesure pour obtenir un second signal, qui est également intégré pour obtenir un troisième signal dont on repère la valeur maximale par rapport à la position angulaire de l'arbre moteur.  On modifie enfin le réglage de l'allumage en fonction de la valeur angulaire de la position de l'arbre moteur pour laquelle le troisième signal a une valeur maximale.

Abstract: TEMPERATURE SENSITIVE TIMING DEVICE        FOR TOASTER APPLIANCE     Abstract of the Disclosure A temperature sensitive timing control device for a toaster appliance includes a main  bimetal element and a compensating  bimetal element, both mounted on a support member mounted for pivotal movement in first and second directions, but biased toward the first direction.  The main  bimetal element includes a trigger arm normally engaging a latch release member to maintain the member in a set position.  The latch release member when released by the trigger arm, in turn releases the bread carrier latch mechanism.  The free end of the compensating  bimetal element rests on a limiting screw which determines the extent of movement of the support member in the first direction.  A locking member, operated by the toaster bread carrier when the latter is moved into a toasting position, engages the support member to secure it against movement in the first direction.  When the bread carrier is moved to the toasting position, the  bimetal  elements are heated.  The main bimetal element moves the trigger arm in a direction opposite the first direction of movement of the support member, out of engagement with the latch release member, permitting the latter to release the bread carrier latch mechanism for movement of the bread carrier to the nontoasting position and to cause the locking member to be disengaged from the support member.  The compensating  bimetal when heated, moves away from the limiting screw to permit the released support member to move in the first direction, repositioning the trigger arm of the main  bimetal into engagement with the latch release member which is reset by the bread carrier as it returns to the nontoasting position, thereby permitting virtually immediate initiation of the next toasting cycle.

Abstract: NON-TWILL PAPERFORMING FABRIC                    Abstract of Disclosure A paperforming fabric of synthetic, monofilament threads is shown as woven in five, or a greater number of harnesses, the warp and weft threads of which it is comprised being interwoven in a non-regular twill pattern with the threads of each thread system interlaced through the fabric to have sufficient crossovers on each fabric face to produce an even sided fabric.  The knuckle length for the resulting fabric is relatively shorter than for other weaves of five or more har-nesses, and the fabric results in minimal diagonal marking of paper being produced thereon.

Abstract: TURBINE BAND COOLING SYSTEM                Abstract A gas turbine engine comprising a number of annular wall sectors which form a complete circular wall defining a hot gas passage is provided with a cooling system incorporating a plurality of hollow impinge-mint vessels disposed in a circular array within an annular chamber behind the wall. Cooling fluid is routed to the self-contained impingement pressure vessels which are provided with perforations to disperse the cooling fluid into impingement upon the wall. Unlike prior systems, the impingement vessels are not physically attached to the band but, rather, are supported by a structural frame which partially defines the annular chamber and, in the preferred embodiment, also supports the wall sectors. Since the impingement vessel, and not the backside of the wall, is the pressure vessel for the pres-surized cooling fluid, leakage between adjacent wall sectors is greatly  reduced with no loss in cooling effectiveness when compared to conventional cooling systems. Thus, turbine cycle performance is improved.

Abstract: ABSTRACT      In a screw capped bottle, a protuberance cooperates with a notch     in a notch-bearing member so that as the cap is screwed on, the protuberance bears on the notch-bearing member and one or both deforms to accommodate the threading movement until the protuberance snaps into the ntoch to terminate the movement.  When screwing the cap off, there is an initial resistance to movement while the protuberance and/or notch-bearing member deforms.  The protuberance then snaps out of the notch and the cap may be removed.

Abstract: ABSTRACT OF THE DISCLOSURE             A diazo film developer which has a developing chamber that is kept at a temperature above the dew point for the film.  Feed rollers disposed adjacent an intake opening of the chamber are maintained at a temperature above the dew point and advance film to be developed to the chamber. Exit rollers at an outlet opening for the chamber withdraw developed film from the chamber.  The rollers are sealed with respect to the chamber to prevent the escape of aqueous ammonia vapors.  The portion of the exit rollers disposed outside the chamber is subjected to relatively low temperature airstream to cool the rollers below the dew point for the aqueous ammonia vapor.  The exit rollers are continuously rotated so that aqueous ammonia vapor can condense on surface portions of the rollers disposed interiorly of the chamber.  The condensate is then transported by the rotating rollers to the exterior of the chamber and the cooled airflow removes, e.g. evaporate the condensate before it is re-introduced into the chamber.

Abstract: Abstract A digital electronic spark timing control for an inter-nal combustion engine.  Independent parameters  such as engine speed and manifold pressure are measured and encoded as multibit digital words.  A digital memory stores spark advance angle as a function of two inde-pendent parameters.  The digital memory is addressed by the most significant bits of the multibit words to ob-tain coarse values of spark timing.  Interpolation is performed on the coarse values according to the least significant bits of the digital words to produce the spark advance angle appropriate for the measured para-meters.  Means synchronized with engine position, i.e., top center, convert the spark advance angle to spark initiation signal.

Abstract: ABSTRACT           A method and apparatus for the quantitative recovery of solids suspended in a fluid from such fluid involving continuous flow centrifugation.  Samples of the fluid with the particles suspended therein, are simultaneously pumped from a plurality of source locations into a common chamber wherein they become mixed while being continuously fed thereto.          The samples from the mixing chamber flow to a sample splitting chamber from which  a portion is diverted to a continuous flow centrifuge and the remaining diverted to waste.  The quantity of mixed sample fed to the centrifuge is determined so that the quantity of solids collected in the centrifuge can be related-thereto.  The apparatus includes a plurality of pump units, each having a water inlet and a water outlet, a sample mixer consisting of a chamber having inlets thereto for receiving the water samples from the pump units.  The sample mixer com-municates directly with a sample splitting chamber having a first outlet open to atmosphere and a second outlet downstream thereof which is connected to the inlet of a continuous flow centrifuge.
