Abstract: ABSTRACT         Magnesia partially stabilised zirconia materials, having a cubic phase zirconia content in the range 70 to 25 per cent (by volume) and a metal oxide additive which forms an insoluble zirconate,  and a microstructure in the form  of  grains  of  stabilised  cubic  phase  zirconia containing precipitates of tetragonal phase zirconia,  are produced for use at low  (less than 400°C)  intermediate (between 400°C and 700°C),  high (700°C to 1000°C) or very high (greater than 1000°C) temperatures.  The higher the temperature of use of the ceramic material,  the more the tetragonal  precipitates  need  to  be  transformed  into monoclinic  phase  zirconia.   The  extent  to  which  the tetragonal precipitates are transformed is controlled by the way in which a fired,  pressed mixture of the ceramic components is cooled from about 1400°C to about 1000°C. An "ageing" of the ceramic material may be effected by an isothermal hold,  preferably at 1350°C and then at 1100°C, in   the   course   of   cooling   to   room   temperature. Alternatively  the  ageing  may  be  effected  after  first cooling the material to below 800°C.

Abstract: ABSTRACT OF THE DISCLOSURE        A hybrid phase-controlled rectifying bridge includes both controlled and uncontrolled electric valves referred to as thyristors and diodes, respectively. Each of a pair of thyristors is periodically fired at an "angle" that can be advanced or retarded as desired, whereupon load current commutates to the thyristor from the corresponding diode. Subsequently the thyristor is turned off at a desired extinction angle by the action of cyclically operative forced commutation means. To avoid reverse recovery overvoltages across a diode when the desired extinction angle is only slightly larger than the firing angle, means is provided for temporarily preventing any turnoff action during the diode-to-thyristor commutation interval and for an additional interval that gives the diode sufficient time to fully recover its reverse blocking capability.

Abstract: ABSTRACT      A wide range, variable rate clock recovery circuit for NRZ data is provided having a PLL and a frequency synthesizer which share control of a common VCO in single loop realization.  Narrow PLL bandwidths and short acquisition time may be achieved employing the frequency synthesizer to initially control the VCO to produce an estimate of the data frequency which is accurate to within the bandwidth of the PLL.  Once this VCO frequency is attained, the PLL disables the fre-quency synthesizer control of the VCO and provides fine tuning control of the VCO output frequency itself. Single loop realization is achieved with a wide range VCO which includes a narrow range VCO, a frequency divider, and an auto-ranging circuit.

Les additifs selon l'invention permettent d'une part de maintenir en dispersion toute la gamme des paraffines, améliorant les propriétés d'écoulement des bruts et d'autre part, d'empêcher le dépôt des paraffines plus lourdes sur les parois. Le procédé est donc efficace aussi bien pendant le stockage que le transport du pétrole brut.

Abstract: ABSTRACT           A gate closure device for drawing a stretch gate taut during the opening and closing of the gate.  The device includes a pair of U-shaped members each having a post engaging loop or bight portion, one for receiving a stationary or fence post and the other a movable  post of the gate, and a lever member including a pair of substantially parallel legs joined by a bight portion.  The outer ends of the legs of a first one of one of the U-shaped members are connected one each to the legs of the lever member for pivoting of the lever relative to the one U-shaped member about a first transverse axis.  The outer ends of the legs of the second U-shaped member are connected one each to the legs of the lever member at a second transverse axis spaced a distance inward from the first transverse axis for relative pivoting of the second U-shaped member relative to the lever member. Thus when the lever member is pivoted from a position wherein it is projecting upwardly from the first U-shaped members to a closed position wherein it is substantially in the same plane as the first U-shaped member, the second axis is moved to a position disposed on the far side of the first transverse axis relative to the loop ox bight portion of the second U-shaped member so that the post engaging portions of the U-shaped members are drawn closer together. at least two of the members, and possibly all three, have openings which align in the closed position for receiving a lock, such as the loop of a padlock.  One of the U-shaped members may be in the form of a flexible member, preferably having one end which is readily detachable from the lever member.  The device can be readily locked with 2 conventional lock and when a flexible U-shaped member, such as a length of chain is utilized, the device can be used as a portable closer which can be moved from gate to gate.

Abstract: Abstract of the Disclosure A motion-adaptive intepolation method for a motion video signal includes the steps of computing a representative motion vector of a moving object by using a certain number of motion vectors, and implementing a modification of the representative motion vector such that a variation of the representative motion vector at a present frame period with respect to the representative motion vector at a previous frame period is limited to a predetermined range, thus increasing the number of the frames per unit of time by using the modified representative motion vector.  Further, a device for implementing the motion-adaptive interpolation includes motion estimation circuitry for evaluating an estimated motion of the motion video signal.  The motion estimation circuitry has a function to compute the representative motion vector by using original motion vectors, a function to implement a modification of the representative motion vector so as to limit its variation of a present representative motion vector with respect to a previous one, and a function to create a motion vector for motion-adaptive interpolation.  Thus, it is possible to provide an excellent smooth movement reproduction and high resolution in the moving area within the frame of the motion video signal.
