Patent DE-3275052-D1 (DE)
Title: Tone detector and multifrequency receiver using this detector
Inventor: GODARD DOMINIQUE
IPC: G01R23/02
Filed: 1982-06-25
Granted: 1987-02-12
Abstract: The purpose of the receiver is to indicate the reception of a multifrequency signal and to identify said signal. A multifrequency signal is a signal combining two predetermined pure tones, one belonging to a high-frequency range, the other to a low-frequency range. The received signal is sampled at 8 KHz and digitally converted. The signal provided by the converter is simultaneously processed by two tone detectors. Each tone detector comprises: a bandpass filter covering the high- or low-frequency range and supplying the components (x, y) of the filtered signal in Cartesian coordinates; decimation means at the output of said filters; a converter converting the Cartesian coordinates (x, y) into polar coordinates ( rho ,  theta ); and logic circuits analyzing the variations of said  rho  and  theta  over fixed periods of time to derive therefrom an identification of the received tone.

Title: Method and arrangement for detecting a particular bit configuration in a serial bit stream
Inventor: SPAGNOL VICTOR
IPC: H04L69/40
Filed: 1984-06-29
Granted: 1988-11-03
Abstract: The bit sequence is stored as a decision table in a memory (60), consulted at the address given by a counter (34) as each bit is received on the serial transmission line (12). If the bit found at that address coincides with the one received, the address counter is incremented and the next bit awaited. If the specified address is zero it is held at that value while another bit is awaited; and if not, the counter is reset to zero and the bit on the line is presented to the table again at the zero address. The complete sequence is detected when the count attains the number of bits sought and the last comparison is positive.

Abstract: A continuous wave laser light beam is directed at the refractory lining within a furnace vessel, and the displacement as measured by a self-scanned linear array of the scattered light beam from a nominal or reference position measured to provide an indication of lining wear or damage. The video signal received by the linear array receiver provides information for mapping the worn or damaged areas of the vessel lining so that such areas may be repaired by a gunning spray nozzel. The inspection apparatus includes an optical filter which is temperature controlled to prevent wavelength shifts away from the nominal laser wavelength. The electronic processing circuitry includes a voltage controlled oscillator responsive to the average background level for modifying the scan rate of the linear array to compensate for changes in background level. The threshold against which the reflected laser beam video signal is compared is also a function of background level. Consequently, the system is self-compensating for changes in background radiation temperature. The apparatus may be lowered into a hot furnace vessel following each heat without the need to cool the furnace vessel. The inspection apparatus is mechanically scanned vertically and angularly within the vessel to provide a large number of inspection data points.

Abstract: A method of treating clay with acid to beneficiate the clay for increased capacity of filtration of oil-soluble colorant compounds from oil. The clay is ground to a particle size distribution such that more than 50% by weight of the clay, on a dry basis, passes through a 200 mesh screen and less than 5% by weight of the clay, on a dry basis, is finer than 5 microns. After grinding, the ground clay is directly contacted with an acid solution to form an acid slurry of the clay. The clay acid slurry is agitated for a time sufficient and at a temperature sufficient so that the acid reacts with a portion of the clay and, thereafter, the acid treated clay is separated from the acid solution; the clay then is washed to remove most of the acid solution from the clay; filtered to a liquid content less than about 60% by weight and thereafter dried to a liquid content less than about 20% by weight.

Abstract: A catheter for opening constricted regions in the cardiovascular system includes an expandable dilatation zone comprising three dilatation elements arranged around a support tube. The dilatation elements are of tubular configuration, and each communicates at one end with a passage in the support tube leading to a pressure-suction pump. Constricted regions in the cardiovascular system may be enlarged or opened by introducing the dilatation zone into the affected site in a folded condition and expanding it peripherally therein. Upon expansion of the dilatation elements flow passages are formed between these elements, through which body fluid (for example blood) can pass with little resistance. The supply of body fluid to organs and tissues downstream of the affected site is thereby maintained. Interruption of the dilatation treatment is not required to insure this supply, thus permitting a substantial reduction in the overall duration of the medical procedure. The catheter may be employed, for example, to dilate blood vessels constricted by arteriosclerotic lesions and in valvuloplasty procedures, and may also be employed for treating constrictions in the esophagus.
