Patent DE-2062193-B2 (DE)
Title: Forced commutation of thyristor in DC circuit - employing shunt connected saturable transformer and auxiliary thyristors
IPC: H02M1/06
Filed: 1970-12-17
Abstract: The circuit comprises a saturable transformer with a square loop characteristics whose primary winding is connected to the d.c. source via a commutating thyristor and a capacitor. The transformer secondary is connected across the main thyristor and controlled by a pilot thyristor. The commutating voltage pulse is applied to the main thyristor by firing the pilot thyristor shortly after the commutating thyristor as, or just after, the core saturates. The capacitor is chosen such that the current flowing is reduced to below the holding current of the commutating thyristor at the start of saturation. The reset current for the transformer secondary winding is less than the pilot thyristor holding current.

Title: Determination of molecular orientation of material surfaces - enables rotation of test-piece under hardness probe for optical projection of indentation profile
IPC: G01N3/42
Filed: 1971-01-20
Abstract: The surface hardness tester comprises an adjustable support table (7a) which allows the test piece to be orientated under the probe (1). By this means a series of hardness readings can be obtained for determination of the molecular structure of anisotropic materials. The support point (7a) is fixed but a supporting table with central aperture aligned directly over the pillar allows the specimen to be moved in all directions. A light source (4) illuminates the point of depression via an infrared filter (3) and fibre optic light guide (2). A lens (8) focusses the profile onto a ground-glass or matt screen.

Title: Pusher heat treatment furnace - with slag removal pockets in floor of equalising zone
IPC: F27B9/22
Filed: 1971-07-28
Abstract: The equalising zone connected to the furnace has pockets in its floor which serve for the removal of slag collecting on the floor. The pockets have slanted bottoms and have an outlet to atmosphere at the lowest point, near which is fitted a burner for melting any slag that may have collected at the bottom. Pref. the burner is fitted to a removable access door to the bottom of the pocket. Melting of the slag in the pockets obviates the need for chipping off any adhering slag. The pockets are flush with the slide bars in the pushing direction. Used for steel ingots or suchlike.
Patent DE-2152875-B2 (DE)
Title: Triggering circuit for controlled semiconductor - limits interference switching harmonics by creating artificial zero voltage crossover point
IPC: H02M1/08
Filed: 1971-10-23
Abstract: The system is used to control loads, for example heaters, fed from a two phase supply, in which the switching is to take place at zero voltage in order to limit the generation of interference harmonics. The load is controlled by changing the ratio between fully conducting and fully blocking periods of the controlling semi-conductor, for example a triac (2). As there is no reference point available an artificial one is created between the two phases (R, S) and the control circuit (3) arranged to detect the point of zero difference between the two phase voltages. This information is then used to determine the zero voltage point where switching of the current to the load (4, 5) can take place without generating noise.

Patent DE-2853422-B2 (DE)
IPC: H02J7/02
Filed: 1978-12-11
Abstract: The invention relates to an electronic timepiece provided with an electroacoustic transducer for transmitting acoustic signals to indicate a time of alarm, and also for receiving information in the form of acoustic signals to control different functions of the timepiece. Coded acoustic information is delivered to the transducer, for example, by a special apparatus intended for that purpose, and serve to control different functions of the timepiece through a watch and transducer control logic network. The logic network is interconnected with the frequency divider chain, a display control circuit, and a transducer. The logic network includes a selector which connects the transducer either to the output of an alarm logic circuit for delivering alarm signals to the transducer at the time of alarm, or to a transducer detector for transmitting the electrical signals delivered by the transducer acting as a microphone to a watch logic circuit. The watch logic circuit, in turn, controls the alarm logic circuit, the frequency divider chain, and the display control circuit of the timepiece.

Abstract: A method of tissue compression is disclosed herein where the device to cause such compression is composed of a fastener bar and receiver. The device has the capability to self-adjust to tissues of varying thicknesses to cause hemostasis. This tissue gap variability allows for compression of regions of tissue where thick and thin tissue are both present. This variability also enables the same device to be used on a wide variety of tissues of different thicknesses. The tissue fastener bar of this invention contains a series of cut-out portions which distribute the compressive forces along the device in an alternating, staggered manner. The receiver is of a generally U-shaped configuration with the fastener bar being contained at least partially within the U-shape. Compression occurs between the side walls of the receiver and the fastener bar and variability in gap is accomplished by flexure of the side walls of the receiver. Varying side wall flexure is enhanced by cut-out portions in the receiver which allow each segment to flex somewhat independently. A number of options also exist for configuration of the fastener bar and/or receiver with the same basic method of compression being unchanged.

Abstract: PROBLEM TO BE SOLVED: To realize a semiconductor manufacturing jig contributing to the downsize of semiconductor elements and a method of mounting the semiconductor elements, using the jig. SOLUTION: A semiconductor manufacturing jig for gripping and carrying a square semiconductor element 101 has four grips having corners, corresponding to the side faces of the four corners of the element 101, so that the grips engage with the four corners. According to such a constitution, the top end of a collet 102 enters into facings at only the four corners of the element 101 and in the vicinity thereof and it suffices to consider only regions, corresponding to the four corners periphery of the element 101 where the top end of the collet 102 enters. Hence there is no need for forming larger facings over the entire periphery of the element 101, such as in prior art, the element 101 may be disposed nearer a pad 106 on a circuit board, and a semiconductor device can be greatly downsized.

Abstract: PROBLEM TO BE SOLVED: To obtain high-quality analysis parameters by subjecting the musical tone waveform data to be analyzed to a spectral analysis, determining the central frequencies and band widths of the respective filters of a filter bank and obtaining the analysis parameters by using this filter bank. SOLUTION: Since the frequencies of the respective partial tones of piano tones are deviated from integral multiple of a pitch, the central frequencies of the respective filters are set according to the degree of the deviations of the respective partial tones of the actual piano tones and the passive band widths of the respective filters are successively widened according to the ways of the deviations so that the band over the entire part of the filter bank is evenly covered. The central frequencies of the respective filters are determined by actually analyzing the piano tones, determining the degrees of the deviation of the frequencies of the respective partial tones and determining the central frequencies according to thereto. When the frequencies of the respective partial tones are determining by mathematical expressions, the central frequencies of the respective filters may be determined according to these mathematical expressions. Further, the combination use of a method for determining the frequencies of the respective partial tones by actually analyzing the original tones and a method for determining the central frequencies by using the mathematical expressions is equally well.
