Patent EP-0309003-A2 (EP)
Inventor: STOKES ROBERT BRUCE
IPC: G01R23/17
Filed: 1985-02-07
Abstract: A surface acoustic wave (SAW) device con­figured to operate as a spectrum analyzer, and having an array of input transducers disposed on a substrate in such positions as to produce a focused beam of acoustic energy at a focal arc, each position on the arc being representative of an input signal frequency. Output transducers produce electrical signals corres­ponding to the energy received at successive segments of the focal arc. The disclosed device includes various combinations of input transducer array improve­ments, some of which are to provide amplitude weighting of the input array, including aperture width weighting, capacitive weighting, resistive weighting, series­parallel weighting, and source withdrawal weighting. Another improvement in input array configuration eliminates close or overlapping electrodes of opposite polarities and thereby reduces parasitic capacitance and acoustic radiation between electrode elements. The use of curved input transducer fingers improves opera­tion of the tranducers as point sources. Other im­portant improvements include the use of acoustic transducers before to transmit the focused output energy from the focal line to conventional output transducers, thereby improving frequency resolution, and the use of electromagnetic waveguides to transmit energy from output transducers located on the focal line.

Abstract: The gas (7) to be cleaned is blown at high velocity by jets (6) against one or more gas-impermeable collecting mats (8) which are arranged directly in front of the jets, and which have, on the side facing the gas to be cleaned, an absorption layer that is gas-permeable and can absorb liquid to a high degree. Particles contained in the gas thus remain suspended in the layer mentioned, while the gas flows off through the spaces (24) round the collecting mat. The collecting mat (8) can be formed as a circulating endless belt, dipping at its lower end into a liquid (17), in which the contaminants are washed out and the mat is again charged with liquid. Alternatively, a plurality of collecting mats may be present, of which each is stretched on its own rotating roller. <IMAGE>

Abstract: The deburring of moulded articles brittle at low temperatures by cooling and applying a blasting medium has hitherto been carried out in rotating drums or conveying belts with circulating devices. In an intermittent mode of operation with prolonged stoppage times, considerable coldness is required for cooling down the deburring device to the operating temperature, since both the movable and the fixed parts of the device have to be cooled down. Since the mass of the rotating or circulating parts of the device is very large with regard to the mass of the moulded articles to be deburred, considerable drive power is also required. …<??>In order to make possible an energy-saving mode of operation during continuous and intermittent operation, the moulded articles are circulated in a fixed circulation container (1) by means of a cold delivery-gas flow directed in the circuit. The circulation container can be subdivided into a vertical acceleration zone (4) and an adjoining expansion zone (5) from which the moulded articles pass back into the acceleration zone after every circulation. …<IMAGE>…

Abstract: An output of an electric driven blower (2) in a cleaner main body (1) is controlled in response to a detection value of a pressure sensor (12) which detects an operation condition in the cleaner main body (1). A change-over level setting value (C₁ , C 1′ ) is provided as an control value for the sensor (12) so as to form a judgement point for changing over a control condition of the blower. A return level setting value (C R′  C 2′ ) is provided as a control value for the sensor so as to form a judgement point for returning to a previous control condition of the blower (2) from a changed-over condition of the blower. When the detection value of the sensor (12) is more than the change-over level setting value, the return level setting value is set higher than the change-over setting value, thereby the output of the blower (2) is increased, or the return level setting value is set a lower than the change-over level setting value, thereby the output of the blower is decreased.

Abstract: A method of administering secure access to files of a computer system. For a process-file pair, a first security label associated with the process is compared with a second security label associated with the file in response to a request to read or write the file. If the security label of the destination (file or process) of the read or write operation does not dominate the security label of the source (file or process), the security label of the destination is dynamically raised accordingly. If the security label of the file or process is raised, an indicator associated with this process and with this file is set to a first state representing that the file is safe for this process-file pair. Indicators associated with every other process linked with this file are set to a second state representing that the file is unsafe for those process-file pairs. The steps of testing the security labels of a file and a process on a read or write operation are omitted when the indicator associated with the process-pair is set to the safe state. 
     The security labels of certain files are assigned a frozen status. These security labels of such files cannot be altered in response to attempted read or write operations. Therefore, an attempt to write a file having frozen status is denied when the security label of the writing process dominates that of the file. This mechanism is used to guarantee that files cannot be written to media external to the system, such as terminals, disk drives, tape drives and the like, unless the security label of the external media clears the media for access to the file.

Abstract: A process for impregnating a glass fiber mat (18) with a resin (16), and for producing composite structures having impreg­nated glass fibers, is provided which substantially reduces the number of voids in the resulting structure, provides fast and efficient heating of the materials, and requires low cap­ital cost equipment to perform the process. The process includes heating a glass fiber mat (18) and an RF-sensitive resin (16) in a radio frequency electromagnetic field to quickly heat the mat and resin, the resin flowing into voids in the glass fiber mat, thereby impregnating the mat; forming the result­ing composite structure into a desired end shape; and cooling the structure. Reduction in the number of voids is advanta­geously accomplished by impregnating the resin into the mat under vacuum, which removes air and decomposition products which result from the RF heating of the resin. Impregnation, molding of the shape, and cooling of the structure may all be performed in a mold if desired, and elongated profiled parts may be continuously produced from elongated sheet stock by passing the heated structure through roll forming dies.

Abstract: A FM signal is applied to a variable gain amplifier (5) of an FM demodulator. The gain of variable gain amplifier (5) is varied in response to a gain control signal. The output signal of variable gain amplifier (5) is applied to an FM demodulating circuit (7) constituting a PLL circuit via a BPF (6). The output signal of BPF (6) is also applied to a synchronous detector (12) via a 90° fixed phase shifter (11). The output signal of a VCO (10) included in the PLL circuit is applied to synchronous detector (12) as the reference signal. The synchronous detector (12) is responsive to the reference signal for synchronous detecting the output signal of 90° fixed phase shifter (11). The output signal of synchronous detector (12) is applied to variable gain amplifier (5) via a LPF (13) as the gain control signal. Thus, variable gain amplifier (5) is responsive to the output signal of synchronous detector (12) for making the amplitude of the FM audio signal included in the FM signal constant.
