Patent EP-0052953-A1 (EP)
Inventor: JANDRASI FRANK J
IPC: F16K1/20
Filed: 1981-10-29
Abstract: A shut-off valve (10) for high temperature solid or liquid erosive flow comprises a valve body (16) formed with an inlet passageway (18), an enlarged internal chamber (20) and an outlet (22). The entry (24) of the passageway (18) into the chamber (20) defines a valve seat (26) formed with an outwardly tapering surface, and a valve member (30) has a correspondingly tapered surface adapted to seat with the surface of the valve seat (26). The valve member (30) is coupled to a shaft (14) which is powered for rotating the valve member (30) into engagement with the valve seat (26) for closing the valve, or back out of the path of direct flow through the passageway (18) when the valve is open. For accomodating thermal growth and contraction of the parts, the valve member (30) is coupled to the shaft (14) by a loose coupling permitting a degree of universal movement to the valve member (30). The design of the inlet passageway (18) at the entry (24) into the chamber (20), and the arrangement of the valve seats, is such that erosion of the valve body commences upstream of the valve seats and can reach substantial proportions without detracting from the effectiveness of the valve.

Abstract: On a measuring table (1), a bridge (2) extends over a printed sheet (5) to be measured. A measuring carriage (3) carrying a three color-simultaneous measuring head is arranged on the bridge (2) for linear movement in a back-and-forth manner along a desired path on the printed sheet. For control of the movement of the measuring head during measuring runs and for the evaluation of the measured data, a computer (7) with an integrated image display terminal and a processor system (6) controlled by the computer, is provided with the necessary interfaces. The analysis of a color measuring strip (MS) located along the desired path on the printed sheet is effected in two phases. In a first, so-called recognition run the measuring strip is scanned stepwise with high resolution in all three color channels, for the purpose of an analysis of its configuration. By means of flat locations in the density variations, effective positions (e.g., the centers) in the measuring fields are determined as possible measuring positions for subsequent measuring runs. During the measuring runs the measuring strip is measured only at the measuring positions determined during the recognition and the measured data obtained in this manner are transmitted for processing and/or display to the computer (7). By the division of the measurements into a recognition and a measuring run, coupled with the determination of measuring positions by means of flat locations in the density variations, a practically completely automatic evaluation of the color measuring strips independently of their configuration and without the need of prior knowledge of the strips by the apparatus, is rendered possible.

IPC: H04B1/66

Abstract: A method and a circuit for narrow band voice transmission is proposed which leads to a particularly large reduction of the required transmission bandwidth. The method emerges from a voice frequency band (VF) which is divided up into three frequency bands, namely a lower frequency band (FBU), a centre frequency band (FBM) and an upper frequency band (FBO). The lower frequency band characterises the vowels of the voice, the centre frequency band the lower frequency range of the consonants and the upper frequency band the upper frequency range of the consonants. The centre frequency range is excluded from transmission. The envelope curve frequency band (FBO') is derived from the upper frequency band and is converted into a frequency range which is adjacent to the lower frequency band. In this way, in the case of analogue signal transmission, instead of the original voice frequency band (VF), only a frequency band which is smaller by approximately two thirds is transmitted. <IMAGE>

Abstract: The present invention relates to a loom control system operable to stop the loom in the presence of a yarn breakage. This loom comprises a feeding device 1 having a yarn storage drum 2 for temporarily storing the yarn and a yarn store sensor 6-9, 20, 30 sensing the quantity of yarn stored on the drum of the feeding device for transmitting an electric sensor signal representing the quantity of yarn stored on the drum to the feeding device to control the operation of the feeding device and to thereby control the quantity of yarn stored on the drum. 
     Prior art loom control systems required complicated, costly and unreliable sensors for detecting whether a yarn breakage has occured or not. 
     The present invention improves this state of art by providing a loom control system of the above-mentioned kind with a monitor means being electrically connected to the yarn store sensor for receiving the sensor signal, wherein said monitor means derives information on yarn breakage before and/or after the feeding device from said sensor signal or its variation with respect to the time to generate a stop signal for the loom.

Abstract: The charge is smelted, then treated metallurgically or secondary- metallurgically and afterwards cast into ingots which are then mechanically deformed. To reduce waste or to eliminate it entirely and to simplify the overall process up to the finished blank, the cast ingots are cooled until they have solidified throughout, the temperature of each ingot in all zones always being above that critical temperature at which stress cracking can occur. The solidified ingots are then heated to the forming temperature and formed immediately after this heating. In installations for carrying out the process, which comprise a melting furnace, a metallurgical vessel, a casting stand and a forming device, a heating furnace is located in the immediate vicinity of the casting stand, the heating furnace being followed by a forming device, preferably a hydraulic forging machine, which ensures controlled forming through to the core of the material.

Abstract: A clock signal regenerator comprising a frequency control loop (1,2,3,4) which comprises a variable-frequency clock signal generator (2) is inter alia used in digital telephone exchanges, when a local clock signal must be generated from incoming clock signals (1-1, 1-N). The clock signal regenerator comprises a very stable auxiliary signal generator (9) and a first difference signal producer (11) for determining the frequency difference between the generated clock signal and the auxiliary signal. This frequency difference is determined periodically and written into a storage device (13). ln addition, the regenerator comprises a second difference signal producer (14) in which the difference is determined between a new frequency difference determined in the first difference signal producer (11) and the preceding frequency difference stored in the storage arrangement (13). Afther the incoming clock signals (1-1,...1-N) have dropped out the difference signal produced in the second difference signal producer (14) is applied as a control signal to the clock signal generator (2), the content of the storage device (13) not being changed. This has the advantage that the stability of the clock signal regenerator is then the same as the stability of the auxiliary signal generator.

Abstract: A focus state detector has light receiving transducers (6A, 6B) formed so that the light levels received on the respective light receiving surfaces (5A, 5B) differ depending on the distance from an object that is to be viewed or photographed. 
     In conventional focus state detectors for detecting whether an optical image of an object is in a correct focusing state with the image clearly formed at a predetermined image forming surface, if the object to be photographed is dark, or if a dark-ground optical system is used, the detector output of the or each light receiving transducer element will generally be so small that focus state detection is virtually impossible, or at best the precision of the focus state detection will be relatively low. 
     To overcome this problem means project a light onto an object (9) through a small aperture (4) to provide a spot illumination for focus state detection, and the light receiving transducer means (6A, 6B) are so formed that the light levels reaching the respective light receiving surfaces (5A, 5B) differ depending on distance from the object (9).
