Abstract: Devices and methods for Intra prediction are provided. The method includes: obtaining a value of an indication information of a current block. When the value of the indication information indicates the intra prediction mode of the current block is not comprised in the set of most probable modes, deriving the intra prediction mode IntraPredModeY[ xCb ][ yCb ] of the current block by the following ordered steps: i. IntraPredModeY[ xCb ][ yCb ] is set equal to intra_luma_mpm_remainder[ xCb ][ yCb ], ii. The value of IntraPredModeY[ xCb ][ yCb ] is incremented by one. The method can improve the efficiency to determine the intra prediction mode of the current block.

IPC: C07C409/24

Abstract: The invention provides a process and apparatus for liquid-liquid extraction in which a first liquid phase is passed continuously through a series of extraction stages (10) whilst a second liquid phase is passed continuously through the series in counter-current to the first phase. In each stage the second phase is dispersed as by a sieve plate (11) and then allowed to coalesce into a settled body (14) from which the second phase is withdrawn and passed to the next adjacent stage. The invention is characterised by the fact that the flows of the two phases in each stage are generally transverse to each other. Preferably the first phase flows through the series of stages under gravity whilst the second phase is pumped (16) from stage to stage to control its inter-stage transfer. 
     The invention combines the features of separate control of residence time characteristics of an extraction column with the safety aspects inherent in a mixer/settler battery.

Abstract: Die Erfindung liegt auf dem Gebiet der Flüssigkristallanzeigen und bezieht sich auf die Herstellung einer Orientierungsschicht, in die zueinander parallele Rillen mit Hilfe eines ebenen, stehenden Wellenfeldes eingebracht werden. Erfindungsgemäß ist vorgesehen, das Wellenfeld aus Ultraschallwellen aufzubauen. In einer bevorzugten Verfahrensvariante haben benachbarte Rillen einen Abstand, der etwa der halben Wellenlänge des Beleuchtungslichtes entspricht, und enthalten die zwischen benachbarten Rillen befindlichen Wälle der Orientierungsschicht jeweils einen Streifen aus einem leitfähigen oder dichroitischen Material. Eine solche Schicht orientiert und polarisiert. Die Streifen können dadurch erhalten werden, daß man dem Schichtmaterial einen leitenden oder dichroitischen Zusatz beigibt oder daß man auf die Orientierungsschicht in einem weiteren Schritt ein Streifenmuster aufbringt. Das vorgeschlagene Verfahren eignet sich für alle Arten von Flüssigkristallanzeigen.

Abstract: A synthetic vascular graft of internal diameter in the range of 0.1 mm to 20 mm and wall thickness between 0.075 mm and 2.0 mm is preferably made by electrostatic spinning of polymeric material. Under an elongation of between 5% and 25% over its unstressed state, the change in internal pressure from a first pressure to a second pressure, the difference between the first and second pressures lying in the range between 20 mm Hg and 75 mm Hg, undergoes a change in internal diameter substantially equal to the change in internal diameter experienced when a corresponding natural artery stretched to an extend experienced in vivo is subjected to the same change in internal pressure. The graft is made by electrostatically spinning an organic polymer material.

Abstract: A TW-EDM method and apparatus wherein a continuous electrode wire (1) is axially transported from a supply side to a takeup side to travel trough an electrically conductive workpiece (2) while a relative displacement is effected between the travelling wire (1) and the workpiece (2) such that the wire (1) is advanced in the workpiece (2) along a prescribed cutting path (4) transverse to the travelling axis of the wire (1) as electroerosive material removal proceeds by the action of electrical discharges across a machining gap (g) flooded with a weakly conductive aqueous machining fluid (F) and maintained between the advancing wire (1) and the workpiece (2), thereby progressively cutting the workpiece (2) along the cutting path (4) and developing a groove of cutting (2a) behind the advancing electrode wire (1).

Abstract: Electronic starter circuits for discharge lamps have been proposed employing the pulse producing properties of a non-linear dielectric element.

The starter includes a semiconductor switch (S) and a diode steering circuit (D1, D2, D3) which connects the switch across the circuit input terminals (4, 6) in one polarity to pass preheating current through the lamp cathodes (2, 3) and in another part of the starting cycle connects the switch (S) in the opposite polarity in series with the non-linear dielectric element (CV) to apply an ignition voltage pulse across the lamp (1).

Abstract: In a quadrupole ion store or ion trap type mass spectrometer, significantly improved mass selection is achieved by scanning the applied RF and DC voltages or the frequency ω sequentially to render unstable trapped ions. These are passed out through apertures in an end cap to a high gain electron multiplier to provide a signal indicative of the ion mass. Sensitivity and mass resolution is also enhanced by operating the ion tape at a relatively high pressure in the range 1 X 10 -1  to 1 X 10 -5  torr. The presence of collision gas molecules, such as helium, improves sensitivity and mass resolution. In addition, the structure itself is built of stacked units, sealed by 0-rings, which are easily disassembled for cleaning.

Abstract: Piezo-ceramic articles, in particular small piezo-ceramic tubes, are metallised, in which the piezo-electric sintered material consists of lead zirconate/titanate and, to obtain a piezo effect, the small hollow-cylindrical tube must be coated on the inside and outside in the radial direction with conductive layers. Such small tubes have hitherto been individually provided manually with metallic layers. Currentless metallisation, though promising, has hitherto led to unsatisfactory results, since the metal layers were not resistant to stripping and, because of the increased contact resistance, higher voltages were required to obtain the piezo effect. According to the invention, the workpiece is subjected in a separate process step before the metal coating to an ultrasonic treatment in an alkaline solution containing a wetting agent, optionally preceded by ultrasonic treatment in water which likewise contains a wetting agent. An alkali metal carbonate or hydroxide and/or an alkali metal phosphate is preferably used for the alkaline solution.

Abstract: @ An apparatus for transferring a relatively flat object from a first station (10) to a second station (60) includes a support (11) for the object at the first station, a substantially closed housing, and a piston disposed therein for sliding movement from a normal position to an activated position. An actuator (112) extends through the housing and is integrally formed with the piston for sliding movement thereby. Compressed air is selectively directed into the housing for movement of the piston to the activated position, whereby the actuator (112) strikes a blow edgewise of the object for propelling it toward the second station along a predetermined path (116). A pair of fingers (130) disposed at the second station define therebetween a portion of the path along which an incoming object enters the second station. Each finger includes a path wall having an end surface extending generally inwardly from the finger for blocking the object path for halting object movement. A spring pawl extending partially into the path from each finger prevents rebounding of the object from the end surfaces.
