The space defined by the sensor housing (1) and the cover (7) is hermetically divided by a sensor housing cover (9) in such a way that inside a front measurement volume (11) a pressure sensor means (15) is placed. This pressure sensor means has a substantially flat shape. It is connected to the interior walls of the front volume by means of tubes (23) which are slender or slim, that is have a small section in relation to the area of the pressure sensor means (15). The carrying means (23) are preferably realized as metal tubes and in their interior the electrical connections (31) for the pressure sensor means pass. By this construction the exterior surface of the whole of the pressure sensor means (15) will be subjected to the measuring pressure.

The electrical connections are also well protected against corrosion by the measurement medium and obtain an electrical shielding.
Patent SE-8803311-D0 (SE)
Filed: 1988-09-19
Abstract: A long coded pulse is transmitted, and the reflected pulse is received back, then reduced to the base band. The signal is fed to the delay connection (F) of a transversal filter. Along the delay connection are several outlets (1,2....n). Their output signals are multiplied by their respective wts. -(W1, W2...Wn) and fed to a summation unit (Sigma). In this unit, for each sample incidence is formed a number of sums with changing time-bandwidth products from successive outlets. The sums are fed to a comparator which selects in each case the greatest signal envelope, and thus the greatest degree of pulse compression. Alternatively, the max. quotient is selected between the largest sum and one based on a low time-bandwidth product. In this case, the quotient comprises directly the filter output signal, and the time variable gain is automatically obtained.

Abstract: The circuitry of the present invention taps a DS0 data stream and outputs a timing signal to drive terminal multiplexers. Even if the data bit stream is lost, the present invention continues to provide proper clocking signals. A composite clock (bit and byte clock) is provided by the present invention with the bit clock at 64 KHz and the byte clock at 8 KHz in the preferred embodiment. To avoid the problem of phase shift over long distances (limiting cable length) the present invention phase adjusts the digital bit stream clocking signal with a 360 degree delay, giving the appearance of advancing the signal in phase. An additional delay of one frame width is applied to the signal. A negative phase delay equivalent to cable runs from 0-1500 feet in 500 foot increments is also applied. In the preferred embodiment, a shift register is tapped in reverse order to accomplish this phase delay.

Abstract: To minimize the clearances and the spread of the clearances between the interacting rotors in rotating machines of displacement type, working as compressors, expanders, pumps and similar machines, the flanks of at least one of the rotors (22) is in a preparative manufacturing operation given an overdimension (17) by cutting, chemical, electrical or plastic treatment which results in a rotor surface with closely located elevations in shape of ridges (19) or pyramides with a preferred run parallel to the run of the sealing zone between the interacting rotors. By rolling down against a special tool (30) or against the interacting rotor (20) itself, the elevations thereafter are pressed down to a part of their height to the contour (18) which gives the wanted minimized clearance towards the flank surfaces of the interacting rotor. The recesses between the elevations (19) can be filled with ceramic, polymeric or metallic material. At an alternative application on precision gears the clearance between the teeth (15, 16) is reduced in an analog way.

Abstract: Method and arrangement for determining a pitch frequency in an analog acoustic signal, which forms part of a mixed analog signal lying in a speech frequency range and composed of a plurality of acoustic signals with different pitch frequencies. The mixed signal is first converted to a digital signal in a sampling unit (22). The signal is filtered in a filtering element (24), which is adapted to the speech frequency range, and then analysed with regard to the pitch frequency. The invention is characterised by the fact that the digital signal from the sampling unit (22) and the filtering element (24) can interact so that adjustment to different pitch frequency ranges is made possible during filtering. By filtering the digital signal in the filtering element (24) a first set of filtered signals is obtained for each respective pitch frequency range. Each of the signals in the said first set of filtered signals for each respective pitch frequency range is half-wave rectified in a half-wave rectifier (26) and bandpass filtered in a bandpass filter (27), by means of which a fundamental frequency component for each respective pitch frequency range is filtered out prior to analysis of the pitch frequency.
