Patent EP-0247805-A2 (EP)
Inventor: ROGERS MICHAEL JOHN
IPC: H03K9/06
Filed: 1987-05-22
Abstract: A demodulating circuit includes an exclusive OR gate 1, which has an input 2 for a frequency-modulated signal. An input 3 of the gate 1 is initially low, so that a signal 4 is generated to enable a pulse generator 5 whenever the input 2 is high. The pulse generator 5 generates a train of pulses of predetermined length and frequency and, on the nth pulse, an output 16 of a "frequency divider" circuit 15 causes the input 3 of the gate 1 to go high, thereby disenabling the pulse generator 5. The pulse generator 5 is then re-enabled when the input 2 of the gate 1 goes low, thereby indicating a zero-cross-over point, in the negative-going direction, of the frequency-modulated signal.

Abstract: A method of rolling bar sections, such as beams or girders, in a rolling mill including a reversing roughing or blooming stand and downstream universal stands, universal stand groups or two-high stands. Initially, the bar sections are pre-­rolled in n-passes into beam-blank sections in the reversing blooming stand. Subsequently, the pre-rolled bar sections are cropped at one or both ends. The cropped ends of the bar sections are then introduced into the universal stand, the universal stand group, or the two-high stands located downstream where they are finish-rolled. Cropping of one or both ends of the bar sections takes place after n-1 or less passes in the reversing blooming stand followed by additional passes in the same reversing blooming stand until the n-passes have been completed.

Abstract: A method and apparatus for substantially eliminating measuring inaccuracies in a storage tank leak detection system (22) caused by temperature-induced volumetric changes in the stored fluid product (18) is described. In a preferred embodiment of the method, a limp bladder (34) is connected to an end of a pressure tube (24) having an inlet (30) and a substantially hollow core (32). The pressure tube (24) and the bladder (34) are filled with a medium (42) having a temperature coefficient substantially lower than the temperature coefficient of the fluid product. The pressure tube (24) and the bladder (34) are then supported in a substantially vertical manner in the storage tank (10) such that a first portion of the medium is supported in the bladder (34) in static equilibrium with respect to a second portion of the medium supported in the pressure tube (24). The large disparity between the temperature coefficients of the medium (42) and the fluid product (18) insures that temperature-induced volumetric changes in the fluid product do not vary the level of the medium in the pressure tube (24). Accordingly, variations in the medium level in the tube represent a true indication of leakage of the fluid product out of the storage tank or leakage of a foreign product into the storage tank (10).

Abstract: To equalise the distribution of voltage at a series circuit of gate-controlled semiconductors (V1, V2) having turn-off times of different length, it is first determined by delivering the turn-off signals at the same time, with a low current flowing through the series circuit, which of the semiconductors (V1, V2) is the last one to turn off. Then the deliveries of the turn-off signals to the semiconductors (V1, V2) which previously turned off earlier are in each case delayed at higher currents until, finally, at full operating current, until these semiconductors turn off at the same time as the semiconductor with the longest turn-off time. This delay can be compensated via load-current-dependent correction elements (K1, K2) at the ratio of the instantaneous turn-off current values of two successive conductive phases of the series circuit. <IMAGE>

Abstract: In a speech recognition system, a technique is disclosed for segmenting multiple utterances of a vocabulary word in a consistent manner, to determine a Markov model representation for each segment. Plural utterances of a word are converted to label strings. One is selected as prototype, and represented by a sequence of Markov models. All other strings are aligned against the prototype, using stored probabilities, thereby determining substrings and thus segments which correspond to the labels of the prototype sequence. Corresponding segments of all strings are commonly evaluated to determine finally a suitable Markov model representation for each segment. The concatenation represents the baseform for the word.

Abstract: A radiation protection (50) system is operative within an optical section of a radiation imaging system (20) for protection of an array of detectors (22) of the radiation. The protection system is formed of one or more spark boards (80) arranged in series along a path of radiation propagation, the spark boards having a central window (84) through which the radiation propagates. On a front side of each spark board are arranged a set of electrodes (90) disposed about a periphery of the window. Ground pads are disposed on a back side of each board in registration with the electrodes on the front side to form therewith a set of capacitors. A capacitive-discharge power-supply circuit (70) is connected to a first pair of electrodes in a first one of said boards. In the presence of excessive incident radiation power, a capacitor of the power supply circuit is switched to apply a high voltage across said first pair of electrodes, the voltage being high enough to initiate an arc across the window in said first board. The capacitors and electrodes are connected serially to allow a current of one arc to charge a succeeding capacitor which, upon being charged, initiates a further arc in a process which continues until all arcs have been struck. The array of arcs blocks radiation propagation so as to protect the detectors.

Abstract: In a pattern selecting device for use in combination with a pattern collating device for collating an input pattern with a plurality of registered patterns to produce first through N-th candidate pattern signals indicative of first through N-th candidate patterns which have first through N-th candidate degrees of similarity relative to the input pattern, where N represents an integer which is not less than two and is not greater than the number of the registered patterns, a processing unit processes (n+1)-th through the N-th candidate pattern signals and produces an approximation signal representative of an approximation variable related to (n+1)-th through the N-th candidate degrees, where n is variable from 1 towards N. An estimating unit estimates an n-th estimated degree for an n-th candidate pattern with reference to the approximation variable to produce an estimated signal representative of the n-th estimated degree. A deciding unit decides whether or not a ratio of the n-th estimated degree to the n-th candidate degree is not smaller than a predetermined value and produces an output numeral representative of n-th candidate pattern when the ratio is not smaller than the predetermined value. Instead of the ratio, it is possible to use a weighted mean value of the n-th candidate degree and the ratio of the n-th estimated degree to the n-th candidate degree.

Abstract: The method of making a flat wiring harness consists of a pre-shaping process, a shaping process, and a wire bonding process. In the pre-shaping process, the intertwined wires are combed to be smoothed and straightened out and are pushed by a press block into parallelly arranged grooves in a series of longitudinally lined jigs and kept therein by a cover. In the shaping process, the group of wires thus laid in parallel lines in a series of the grooved jigs are shaped into a desired pattern of the flat wiring harness by moving any desired grooved jigs horizontally along guide slots formed in a holder plate, on which the grooved jigs and associated components are mounted. In the bonding process, the shaped flat wire group is applied with adhesive on one side through a screen which is patterned according to the shape of a final flat wiring harness. As the adhesive hardens, the wires are bonded together and a flat wiring harness of a desired two-dimensional shape is obtained. This method allows the wires of different sizes to be bonded together. It also permits the formation of branch wires at any locations from the trunk.
