Abstract: A fluid ice protection system for an aircraft includes a plenum back wall and a fluid delivery network. The plenum back wall is affixed to an interior surface of an inlet cowl of a nacelle of the aircraft to define a plenum between the interior surface and a front surface of the plenum back wall. The nacelle surrounds a rotor assembly of an aircraft propulsion system. The inlet cowl defines a plurality of perforations through a thickness of the inlet cowl. The perforations are fluidly connected to the plenum. The fluid delivery network is coupled to the plenum back wall and configured to supply an anti-ice liquid into the plenum for the anti-ice liquid to penetrate through the perforations onto an exterior surface of the inlet cowl along a leading edge section of the inlet cowl.

Abstract: System (100) for generating and transmitting vibrations comprising a sound waves source (10) which emits an audio signal at a determined frequency and a transducer (20) operatively connected to the sound waves source (10). The transducer (20) converts the audio signal emitted by the sound waves source into harmonic vibrations. The system (100) comprises, furthermore, a body for propagating vibrations (5) having an elongated geometry, which protrudes along a vertical direction (105) for propagating the harmonic vibrations along determined directions. A transmission device (30) is, furthermore, provided for transmitting the harmonic vibrations produced by the transducer (20) to the body for propagating vibrations (5). The vibration transmission device (30) comprises a receiving portion (35) integral to the transducer (20) and an engagement portion (40) for removably engaging from above with the body for propagating vibrations (5) at respective contact surfaces (36,6) [Fig. 1].

Abstract: Nouveau type de foret pour canal radiculaire qui est, d'une part, assez flexible tout en ayant une resistance suffisante pour pouvoir aller vers le fond de canaux radiculaires incurves sans se casser et qui, d'autre part, possede une grande capacite d'extraction de matiere du canal radiculaire. Ce probleme est resolu par un foret pour canal radiculaire qui presente, le long de la partie qui travaille, deux bords tranchants helicoidaux et continus (8, 10) qui se deplacent l'un par rapport a l'autre sur la partie qui travaille dans le sens longitudinal, de telle sorte que chaque tour d'une des helices a bord tranchant se situe entre deux tours consecutifs de l'autre helice a bord tranchant. L'invention concerne aussi une methode de fabrication d'un tel foret consistant a meuler sur la surface externe d'une ebauche de foret deux cannelures helicoidales, continues (4, 6), ces cannelures se deplacant dans le sens longitudinal de l'ebauche l'une par rapport a l'autre, de telle sorte que chaque tour d'helice d'une des cannelures se situe entre deux tours d'helice consecutifs de l'autre cannelure et que les bords des cannelures forment, le long de l'ebauche, deux bords tranchants helicoidaux et continus (8, 10) qui se deplacent l'un par rapport a l'autre dans le sens longitudinal de l'ebauche. Le foret pour canal radiculaire est essentiellement destine aux soins dentaire pour effectuer des traitements de racines.

Abstract: Metallisierte, textile Flächengebilde aus synthetischen Polymeren oder nativen Fasern, auf denen nasschemisch eine Metallschicht stromlos niedergeschlagen worden ist, eignen sich besonders zur Abschirmung von elektromagnetischen Wellen im Bereich von 10 MHz bis 1000 GHz. Da die textilen Eigenschaften durch die Metallisierung wenig gestört werden, sind die Flächengebilde besonders für den Einsatz im medizinischen und nachrichtentechnischen Bereich geeignet. Ein mehrschichtiger Aufbau mit isolierenden Zwischenlagen und oberflächliche Kaschierungen können beispielsweise bei der Abschirmung relativ niedriger Frequenzen zweckmässig sein.

Abstract: In a frequency modulated carrier wave radar the detection of the beat frequency that represents range is interrupted for short intervals that occur near maxima or minima of the modulating signal (3a) that controls the frequency of the transmitted carrier wave. During these intervals of interruption the carrier wave is modulated in amplitude so that it can convey information (B) to the target that it illuminates. In a preferred embodiment, the amplitude modulation consists of a variable number of cycles of a voltage controlled oscillator (7) of which the frequency is controlled by an integrated signal which represents the beat frequency. Timing for the short intervals of amplitude modulation and somewhat longer intervals that extend before and after each interval of amplitude modulation is derived from a square wave signal (3b) that is produced by an oscillator that governs the frequency of the carrier wave.

Abstract: Transmission of data signals using an optical array keyboard. Light sources 1 and collimators 2 sequentially direct a light beam 8 along the rows of an array of beam-splitting elements, 3, controlled by keys 4. When an element 3 is placed in the path of a beam 8 it reflects part of it towards one of the detectors 7 placed in the columns of the array, but allows the other part to pass towards the other elements 3 situated downstream, thus permitting detection of the state of the other keys of the same row, and resolution of the problem relating to the situation where a key is depressed before the previous one is released. The keyboard can be used as a unit for inputing data into a data processing system. <IMAGE>

Abstract: A bridge plug tool for temporarily plugging off a well casing to perform a downhole operation, such as cementing, or acidizing which includes a mandrel (10) having separate and spaced threaded segments (29,30) thereon. During running-in of the tool into the well casing, one threaded segment (30) engages a set of control members (31) to keep the mandrel in place and to prevent it from shifting longitudinally with respect to the tool. In the set position the control members are disengaged from the mandrel and the other threaded segment (29) engages a set of lock members (32). By applying a weight on the mandrel after threaded engagement of the mandrel with the lock members, a set of slip members (36) and packing elements (19, 20, 21) are caused to engage an inner surface ofthe casing wall to set the tool in position in the well casing. When the downhole operation is finished, the mandrel is rotated to disengage from the lock members (32) and to re-engage the control members (31). This sequence disengages the slip members (36) and packing elements (19, 20, 21) from the casing wall (22) so that the tool (T) can be retrieved from the casing, or re-set at another position in the casing.

Abstract: In an apparatus for use in operating a mechanism such as a valve a single resilient means (29) is utilised for biassing, for example, a valve to both the open and closed positions dependent upon which position is selected. First and .second escapement means (31, 32) are cooperable with the housing (24) and actuator (26), and confine the resilient means (29) in compression. The first escapement means (31) is selectively operable to limit movement of one end of the resilient means (29) relative to the housing (24) or actuator (26), and the second escapement means (32) is similarly operable to limit relative movement of the other end of the resilient means (29). Said first and second escapement means (31, 32) alternatively secure opposite ends of the resilient means (29) to the housing (24) and actuator (26) in response to movement of the actuator (26), whereby the resilient means (29) alternately urges the actuator (26) in opposite directions, providing the desired biassing once a change in the position has been selected.
