Title: Catalyst and prepolymer used for the preparation of polyolefins
Inventor: BAILLY JEAN-CLAUDE ANDRE BP CH
IPC: C08F10/00
Filed: 1990-12-13
Abstract: The present invention relates to a solid catalyst suitable for polymerizing olefins in a heterogeneous process, the catalyst being obtainable by a process comprising (1) contacting a support containing MgCl₂ and an electron donor (D1) free from labile hydrogen with an electron donor (D2) containing labile hydrogen, and (2) then contacting the solid resulting from (1) with a zirconium metallocene, optionally with an organoaluminium compound which is preferably an aluminoxane. The solid catalyst may be used as such in olefin polymerization, or in the form of a prepolymer comprising a (co-)polymer of ethylene, the solid catalyst and an organoaluminium compound. The (co-)polymer of ethylene produced with the solid catalyst or with the prepolymer has a narrow molecular weight distribution and a low zirconium content and is in the form of a powder with a high bulk density, preferably consisting of spheroidal particles with a narrow particle size distribution.

Abstract: The method for stapling layers of paper is based on a bond under ultrasonic action. The sheets of paper are pretreated by means of a bonding agent by printing on, spraying on or impregnation with droplets before, during or after the printing. The ultrasonic action is performed by means of a [lacuna] comprising an ultrasonic vibrator 20 and a control device. The vibrator has a conical or blade-shaped stapling tool, the sonotrode 24. The latter is pressed during the ultrasonic action against the layers of sheets 26 which, in turn, rest against a plate-shaped or ridge-shaped counterbearing 27. <IMAGE>

Abstract: The invention relates to a procedure for determining the mass flow of the individual components of a flow consisting of at least two liquids and a gas in a pipe. According to the invention, a sequence of high frequency magnetic pulses is applied to the flow, and the emission of the nuclear paramagnetic magnetisation, and thus the nuclear spin, is measured from the internal volume of the high frequency coil of a nuclear magnetic resonance spectrometer, giving the average speed and the volume fraction of the liquid phase; a free induction decrease in the flow is then produced and measured by means of a short high frequency single pulse, and its frequency dependence is analysed using a Fourier transform. Finally, the individual volume fractions of the liquid components are determined by computer analysis of the Fourier spectrum. <IMAGE>

Abstract: A microcomputer having a high speed access memory and a compiler capable of producing a compact object including a high speed variable operation is disclosed. As to an input source program, variable areas used by subroutines are calculated by a variable area analyzing part, and a flow graph of an interrelation of callings of the subroutines is produced by a flow graph producing part. Then, the maximum variable area used by a whole program is calculated from the sizes of the variable areas and the flow graph by a maximum variable area detecting part. When the calculated maximum variable area size of the whole program is smaller than the memory size of the high speed access memory, an output part outputs the object information with variables allocated in the high speed access memory.

Abstract: The present invention has the object to provide a fingerprint data processing method possible to calculate easily the significant reference point of a fingerprint image, and distinguish and reduce a false end point generated around the frame of an image on inputting a fingerprint. 
     The steps for calculating the reference point is: i) binarizing a fingerprint image, ii) scanning the binarized image in two directions and counting edges of ridges crossing scan line, iii) calculating distribution of a value counted in ii), as well as calculating a maximal value in both directions among peaks with distribution equal to or more than a predetermined value, iv) settling cross points of the maximal value as a reference point. 
     The steps for distinguishing and reducing the false end point is: i) binarizing a fingerprint image, ii) generating an image in which ridges are fused by expanding the binarized image, iii) scaling down the contour by shrinking the fused image, iv) inputting minutiae of an original image using the image generated by the steps from i) to iii) as a mask.

Abstract: A hand-held device which provides an instrument for reading a bar code symbol. Print quality parameters including print contrast signal (PCS), ANSI (American National Standards Institute) Grade, and other parameters, are obtained by the analysis of the signal resulting from code reading in an internal computer having memory contained in the instrument. A graphic display includes a display device such as a liquid crystal having a matrix of elements arranged in areas which provide a message containing a plurality of dot matrix characters, other areas where the elements are formed into segments for display of alphanumeric characters and still other areas where the elements are formed into legends. The display is driven by a graphics driver. The computer has memory in which data corresponding to a multiplicity of text messages some of which are fixed and others variable, being provided by the results of the print quality analysis. The instrument contains controls for operating the display to provide a menu of instructions and to indicate the analysis parameter being displayed. A graphics driver has an array of storage elements arranged correspondingly to the elements of the display. Data is transferred from memory under program control via the computer to the display. The display is selectively orientable (flippable) to present messages in the message area, characters in the segment area and graphics in other areas in upright position and in proper orientation for readability by use of the controls to set the display to present the messages either in left or right-handed orientation. The instrument can be handled in either the right or left hand and the display presented in readable position. The areas are arranged so as to be mirror-wise symmetric about a longitudinal axis through the instrument so that when the computer writes data into the array of the graphic driver, it is written in an orientation and ordered so that the display presents the graphics upright and in order (left to right in the American system) for viewing.

Abstract: A method and apparatus for detecting and locating a quench zone (13) in a superconducting coil (11) is provided. A sensor (5) is positioned adjacent to and in heat transfer communication with the superconducting coil (11) along the entire length of the superconducting coil (11). When a portion of the superconducting coil (11) becomes normal, the adjacent portion (15) of the sensor (5) becomes resistive. A series of electrical pulses are sent along the sensor (5). At a normal zone, the discontinuity in impedance which occurs at such a zone, causes a reflective pulse (43) to be sent back along the sensor (5). In addition, the sensor (5) may be short-circuited at one end so that a return pulse opposite in polarity (45) to the transmitted pulse will be reflected from that end. Alternatively, the sensor may be open-circuited at the end and a return pulse of the same polarity (50) as the transmitted pulse is reflected back. Yet a further embodiment includes a resistive component (16) of a predetermined value at the termination end. The reflective pulses and the echo pulses are detected by an associated receiver (25) and processor (27) which calculate the location of the resistive zone (13) along the sensor (5) and the corresponding quench zone (13) along the superconducting coil (11) using information derived from the pulses. A second embodiment provides two sensors (61, 63) which are adjacent to and in heat transfer communication with the coil (11) which are pulsed from opposite ends. This provides additional information about the quench zone (84) and also provides redundancy in the system. An associated method is also provided.
