Abstract: A self-venting valve having its principal parts molded of nylon reinforced with glass fibers is mounted in the bottom of a fuel filter assembly to drain water and other contaminants from the assembly. The self-venting valve includes a plunger portion with a bore therethrough for draining water from the fuel filter assembly and a valve body member which receives the plunger. The valve body member has a vent hole therein which communicates with the interior of the housing to let air into the housing so that as the water drains from the housing a partial vacuum is not created which might interrupt the flow of water. The plunger is biased to the valve closed position by a coil spring, however the valve may be held in the open position by misaligning lugs on the plunger with slots in the valve body member.

Abstract: A graphical symbol encoding a numerical value may be accurately read even when placed on a non-planar surface. The marker (120) is imaged with an inventive apparatus and analyzed using an inventive method which translates the graphical image into a unique number for article identification purposes. The marker (120) in its preferred embodiment includes an outer ring (210) having a continuous perimeter in one or more concentric data tracks disposed within this outer ring (210). A timing track is used to determine angular relationships about the center of the marker. Distances (D1-D4) between points associated with the outer ring (210) in a particular data track are used in conjunction with these angular relationships to locate a digitally encoded visual pattern associated with a particular data track. This pattern is being used to store at least a portion of a numerical code used to identify each marker-bearing article.

Abstract: A driveshaft includes a center portion having a larger diameter, an end portion having a reduced diameter, and a diameter reducing portion positioned between the center and end portions. The reduced diameter end portion of the driveshaft is secured to a reduced diameter tube yoke. This facilitates the introduction of tooling during assembly of a universal joint. The driveshaft is formed by a method which involves first heat treating the driveshaft to a relatively soft temper, then swaging the end portion of the driveshaft, and thenheat treating the driveshaft again to a relatively hard temper. In more detail, a driveshaft is provided having a predetermined first diameter, the driveshaft being heat treated to achieve a relatively soft temper so as to possess a desired elongation factor. This allows the end portion of the driveshaft to be swaged toreduce the diameter thereof to a second predetermined diameter. After swaging, the driveshaft is heat treated again to achieve a relatively hard temper to meet the strength requirements for use.

Abstract: The object of the invention is a magnet arrangement for the treatment of ski n or tissue regions of the human body close to the surface, having several mechanically connected magnetic mouldings (M1, M2) forming an effective surface at or near which use is made of the magnetic field there. Use has lo ng been made in therapeutics of flexible magnets of plastic-bonded hard ferrite  having at least one north and one south pole on their effective surface faci ng the patient, where the pole configuration is differently arranged in accordance with the therapeutic purpose. It is thus possible to generate magnetic inductance only in regions of the skin or tissues close to the surface. A magnet arrangement of several magnetic mouldings of high coercive  field strength with different energy densities is proposed to attain locally  limited higher magnetic inductances.

Abstract: In a method for real time speech input of a destination address into a navigation system, the speech statements that are entered by a user are recognized by a speech recognition device and classified in accordance with their recognition probability.  The speech statement with the greatest recognition probability is identified as the input speech statement, with at least one speech statement being an admissible speech command that activates the operating functions of the navigation system associated with this speech command.  (All the admissible speech statements being stored in at least one database.)  According to the invention, at least one operating function of the navigation system comprises an input dialogue.  Following activation of that operating function, depending on the input dialogue, at least one lexicon is generated in real time from the admissible speech statements stored in at least one database, and the generated lexicon is loaded as vocabulary into the speech recognition device.

Abstract: Injection molding apparatus and method wherein a number of cylindrical inserts or plugs each having a curved melt duct therethrough are accurately aligned and securely mounted in spaced cylindrical openings through a melt distribution manifold. An alignment and retaining pin made of a very strong material extends from a bore in the manifold into a bore in the insert. The manifold is heated and the inserts and pins are cooled prior to insertion into place to provide very tight fits when they are at the same temperature which very accurately aligns the melt ducts through the inserts. The combination of the inserts fitting tightly in the openings and the strength of the pins is sufficient to withstand the rearward forces from the pressurized melt being injected through the curved melt ducts to retain the inserts in place.

Abstract: Des mesures particulières doivent être prises pour fixer un composant soumis à la pression d'un fluide, si ce composant est constitué d'un matériau résistant à l'usure, dur et donc, en général, cassant, et peut être détruit par des tensions localement élevées. Un tel composant constitué, par exemple, de silicium/verre, est disposé dans une pièce moulée en élastomère, constituée par exemple d'un caoutchouc à la silicone dont la partie intérieure correspond à la forme extérieure du composant à fixer et dont les contours extérieurs correspondent au contour intérieur d'un élément de fixation. Grâce à cette "fixation flottante" aucune pointe de tension locale inacceptable est possible et le composant ne subit aucune déformation. Ce dispositif convient particulièrement à la fixation d'un tel composant miniaturisé constitué de verre ou de silicium, devant être soumis à des pressions élevées.

Granted: 2007-02-20
Abstract: A desalination plant (10) is disclosed which includes a pump for pumping water at a pressure of between 50 and 65 Bar to a generally cylindrical filter element (30) which includes a plurality of reverse osmosis membranes defining salt passages. Immediately upstream of the filter element (30) there is a disc (40) with a plurality of holes (44) in it.  The disc (40) forms an obstruction which causes a pressure drop between the upstream side thereof and the downstream side. It also divides the water flow into a series of separate streams which impinge on the end of the filter element and flow into the salt passages. The water downstream of the obstruction is not only at a lower pressure than the water upstream of the obstruction but also is flowing turbulently.  The disc (40) and filter element (30) are in a cylindrical casing (12). The brine which emerges from the filter element, and which is still at a substantial pressure, can be fed through a device such as a Pelton wheel to recover some of the residual energy therefrom.

Abstract: A multi-door enclosure for housing electrical equipment has a mechanical interlock device that interacts with a main primary door of the enclosure and the existing latch mechanisms of each of the remaining secondary doors to prevent such secondary doors from being opened unless the primary door is first opened.  The interlock includes a lever arm that engages and is displaced by the primary door when closed.  Such movement of the lever arm is transmitted via a mechanical linkage system to move one or more latch disabling members into disabling relation with the latch mechanisms of each of the secondary doors in order to retain the latch mechanisms in their latched positions and thereby lock the secondary doors in the closed position. Opening the secondary door allows the lever arm to return to its initial position which in turn retracts the latching members and allows unlatching and opening of the secondary doors.
