Patent EP-0370209-A1 (EP)
Inventor: KLEES GARRY W
IPC: F02K7/12
Filed: 1989-10-03
Abstract: A jet engine for use in a hypersonic aircraft. A fuel rich injectant is injected into the mixing zone of a duct at a substantial downstream angle to form an ejector. The temperature of the injectant is sufficiently low that spontaneous combustion of the injectant is delayed until the injectant reaches the combustion zone of the duct. In order to prevent combustion from propagating upstream from the combustion zone, the equivalence ratio of the mixture of injectant and ambient air flowing along the wall of the duct is maintained at a relatively high value, and the velocity profile of the flow along the wall of the duct is maintained at a relatively high value.

Abstract: In a modulo  p  arithmetic apparatus operands are represented as powers of a generator so that multiplications can be performed as simple additions. However, this makes actual addition difficult. Additions are therefore performed by means of a modulo (p-1) subtractor circut (1), a Zech table (2) and a modulo (p-1) adder circuit (3). In order to reduce the size of the Zech table which would otherwise be required, specific values of the output of the subtractor circuit are converted to their negatives modulo (p-1) by means of a converter circuit (15) prior to their application to the Zech table, making use of the fact that each negative modulo (p-1) maps directly to a unique positive number which is often different from the number which was orignally converted. For each number which is converted a multiplexer (18), which normally feeds that input operand (y) which is subtracted in the subtractor circuit to one input (12) of the adder circuit, is switched to feed the other input operand (x) to the adder circuit instead.

Abstract: The invention relates to a process for manufacturing a tubular reinforcing fabric (12) comprising one or more layers of parallel reinforcing yarns (19, 20, 21)  which are optionally shiftable in axial direction while interconnected by binder yarns. The binder yarns are provided by knitting or stitching. In the former case a tubular inlay fabric is formed. In the case of a multilayer fabric it is preferred that subsequent layers of reinforcing yarns have different axial directions and, optionally, are also shiftable in different directions, e.g. through 0°, +45°, -45°, 90°. In tubular or opencut form said fabric can be used as fibre reinforcement for composites.

Abstract: Dans un indicateur de niveau (12), notamment pour réservoirs (10) de carburant de véhicules à moteur, des ondes de flexion (17) sont appliquées à un conducteur de son (11) par un émetteur (13). On détermine les valeurs de mesure grâce à la réaction générée, qui est fonction du niveau (h) et qui influence les dimensions du champ sonore dans le conducteur de son (11) au niveau de l'émetteur (13) ou à proximité de celui-ci (immittance sonore). A cet effet, on évalue les modifications de l'impédance transversale. On obtient un gradient linéaire des mesures qui correspond de manière univoque au niveau (h), à un demi-angle de changement d'angle de phase près.

Abstract: The electrical insulator contains a thermoset matrix in which a filler predominantly comprising powdered materials is embedded. This insulator has a long service life in spite of high mechanical load at temperatures of up to 105 DEG C.

Abstract: A device for controlling a fuel feed pump (A) com­prising a fuel spill passage (40) and a spill control valve (42) arranged in the fuel spill passage (40). The spill control valve (42) is controlled by the pressure of fuel in a pressure chamber (48), and the pressure of the pressure chamber (48) is controlled by the piezoelectric element (47). When the piezoelectric element (47) is driven, the pressure of the pressure chamber (48) is increased, and thus the spill control valve (42) is closed. When the engine speed is high, the piezoelectric element is driven at each 360 degrees of rotation of the crankshaft. Conversely, when the engine speed is low, the piezoelectric element is driven at each 120 degrees rotation of the crankshaft.

Abstract: A method and a device are described for controlling the fuel injection on a high pressure fuel pump. Solenoid valves determine the quantity of fuel to be injected into the internal combustion engine. During the delivery phase of a pump element, the solenoid valve is controlled in such a way that pre-injection is first carried out and then main injection. In certain operating states the control unit determines the duration of the control pulses for the solenoid valve at which precisely one pre-injection occurs. On the basis of the duration of the control pulses, it forms balancing signals for control pulses, which produce a pre-injection, and stores them. …<IMAGE>…

Abstract: A method is disclosed for the quantitative removal and concentration of desired molecules or ions, such as gases, anions and amino acids, from a source solution which may contain larger concentrations of other molecules. The method comprises bringing the source solution into contact with a solid cation-ligand-matrix consisting of a cation complexed to a ligand molecule covalently bonded to a matrix consisting of an organic spacer bonded to a solid inorganic support through a silicon atom. The cation has an affinity for the desired molecules to form a complex between the desired molecules and the cation portion of the solid cation-ligand-matrix at binding sites initially held by H₂O or other weakly coordinated ligands or via ion pairing. The desired molecule complex is broken releasing either the desired molecules or desired molecules complexed with the cation by contacting the solid cation-ligand-matrix-desired molecule complex with a much smaller volume of a receiving solution in which said desired molecules are soluble. The concentrated ions or molecules thus removed may be analyzed and/or recovered by known methods. The process is useful in measuring the concentrations of molecules originally present at parts per billion levels; in the removal of low levels of toxic molecules such as ammonia or anions such as chromate from potable and saline water; in the preparation of ultrapure salts and gases; and in the recovery of valuable molecules present in low concentrations as in the separation of amino acids, etc.

Openings (25) located about the first part pass through the body from the inside to the outside surface. Adhesion means (26) on a section of the inside surface is juxtaposed when the first and second parts are folded along the line. The openings in the first part are on another section apart from the adhesion means. A reinforcement (34) as a thicker area of the first part has ears (35) for the openings. The ears are adjacent a pair of opposite edges, each of which defines an elongate dimension of the body. At least two ears are disposed near each edge with one ear near each edge and the line.

Abstract: An over-pressure relief valve to be positioned within an opening of a vessel (V), the relief valve having a valve member (12) with a closed end which is positioned within the opening (0) and which carries an O-ring (20) adjacent to the closed end. The O-ring (20) normally engages the vessel (V) in a circumferential pattern surrounding the opening (O) to seal the opening (O). The valve member (12) further has a second end  (16) within the vessel (V) and the second end (16) is resiliently biased toward the interior of the vessel (V) by a coil spring (24). The coil spring (24) is trapped between a radial flange of the valve member (12), which is positioned at the second end thereof, and the inside of the vessel (V). An over-pressure condition within the vessel (V) overcomes the effect of the coil spring (24) and moves the valve member (12) to break the sealing engagement between the O-ring (20) and the vessel. An initial, limited degree of venting occurs through an annulus (A) which is formed between the opening and the valve member (12). Further venting occurs, if needed, by way of an internal passage (26) in the valve member (12) which extends from the second end (16) to an opposed pair of radial passages that are positioned entirely within the vessel when the O-ring (20) is in sealing engagement with the vessel.

Abstract: An enclosure for electrical switchgear is a box like structure made up of side panels (2, 4) front and rear panels (6 & 7) and external panels (28).

Thus if the gas filled circuit breaker chamber (20) explodes as a result of a fault developing, the enclosure (14) is relieved of the resulting pressure generated by the expanding gases by venting to a ventilation system via the apertures (22, 24) and the chimneys (26).
