Abstract: On the basis of a finding that a magnetic hysteresis of a metal material, among magnetization characteristics changing with secular degradation of the metal material, shows a clear correspondence with the degree of degradation of the metal material, a change in such a magnetization characteristic is measured to estimate the degree of secular degradation of the metal material. In a typical embodiment, a superconducting quantum interference device (33; 340) is used to detect the magnetization characteristic of a measuring object (1; 11). According to the present invention, the degree of embrittlement of a metal material used in an environment of high tempera­tures can be quickly detected in a non-destructive fashion so that the danger of brittle fracture of the metal material can be reliably prevented.

Abstract: Each drill pipe (3, 3') has an outer tube (11), an intermediate tube (9) and an inner tube (7). The inner tube (7) encloses an inner passage (6) for pressure fluid. There is an intermediate passage (8) for return fluid between the inner tube (7) and the intermediate tube (9), and an outer passage (10) carries flushing medium between the outer tube (11) and the intermediate tube (9). The inner tube (7) can be displaced downwards against the force of a restoring spring (48) and as a result likewise pushes the axially aligned inner tube (7) of the lower drill pipe (3) downwards into a second end position. Only in the second end position can pressure fluid flow from one inner passage (6) into the inner passage (6) located below it via a first connecting passage (30), and the return fluid can pass from one intermediate passage (8) into the intermediate passage (8) located above it through a second connecting passage (31). In the other, first end position of the inner tube (7), the inner passages (6) and the intermediate passages (8) of each drill pipe (3, 3') are shut off so that no fluid can be lost. <IMAGE>

Abstract: A part of a tube (1A), through which a fluid passes, is cooled by means of an elec­tronic cooling element (2) and a flow rate of said fluid is measured on the basis of the temperature of a surface of said cooled tube (1). 
     Not only the flow rate of the fluid flowing through the tube (1) can be determined in a contactless manner and a very small flow rate of the fluid can be determined but also the tube (1), through which the fluid passes is cooled by means of the electron­ic cooling element (2), so that no bubbles are generated. Thus the measurement of the fluid, which is apt to generate gases, such as low boiling point liquid, is possi­ble. In addition, the measurement is not influenced by gases dissolved in the fluid and merely the temperature difference resulting from the flow of the fluid, that is the rise of the temperature of the fluid, is detected to prevent the measurement from being influenced by the assembling position of the flow meter, so that the high-precision measurement is possible. 
     Consequently, a stable and sure controlling of the flow rate is possible.

Dem unmittelbar auf die Wägezelle (9) einwirkenden Uebersetzungshebel (7) ist ebenfalls ein mit Lenkern (3, 4) parallelgeführter Lastaufnehmer (5) zugeordnet. Dadurch lässt sich der mit der Wägezelle (9) zusammenwirkende Uebersetzungshebel (7) und der diesem zugeordnete Lastaufnehmer (5) zusammen mit der Wägezelle zu einer baulichen Grundeinheit (1) vereinigen, die eine selbständige Waage niedriger Nennlast darstellt und in den übrigen mechanischen Teil (13 bis 20) der für eine höhere Nennlast bestimmten Waage eingesetzt ist.

Am zusätzlichen Lastaufnehmer (5) kann sich der Kraftangriffspunkt für ein zuschaltbares Kalibriergewicht (23) befinden. Es ergibt sich damit eine von der Lage des Kalibriergewichts unabhängige Krafteinleitung in den an den Lastaufnehmer (5) angekoppelten Uebersetzungshebel (7).

Abstract: A method and apparatus for introducing a pan and scan feature to a multiple-signal high definition television (HDTV) system, so that a compatible signal received by a standard TV receiver may be a panned version of a wide aspect ratio HDTV signal, and so that high quality recombination of the compatible and augmenting signals by an HDTV receiver is possible. A pan and scan data word representing the relative movement of the compatible portion of the HDTV signal is inserted during the vertical blanking period of each frame of the HDTV signal, for causing panning synchroniza­tion between an HDTV transmitter and an HDTV receiver. The pan and scan data word corresponds to the beginning read address of a fixed coefficient memory containing video attenuation coefficients, which determine the degree of signal attenuation, to be applied at each pixel location along an HDTV scan line. The coefficient memory is addressed in a wrap-around manner, so that if the starting address in the read cycle is other than zero, the reading continues until the highest address in the memory is reached, and then address zero et seq. are read on up to the address before the starting address. By changing the points of pas­sage, attenuation and suppression along scan lines, panning occurs.

Abstract: An improved method and apparatus is provided for estimation of absolute velocity in active or semi-active suspension systems. A controller (12) produces a signal estimate of absolute velocity which can be implemented by a control algorithm to attenuate motion between spaced members (14,16), such as in vehicular suspension systems.

A digital feedback or offset means (38) is utilized to stabilize the signal and constrain the constant and relatively low frequency components of the analog integrated signal about an oscillatory voltage range. A digital filter means (40) receives the stable signal and removes selected constant and low frequency components of the signal to produce a signal indicative of absolute velocities for a frequency range of interest further stabilized about a selected mid-range voltage value.
