Abstract: ABSTRACT OF DISCLOSURE          A METHOD TO AUTOMATICALLY DETERMINE THE SIZE DISTRIBUTION             OF SHIVE AND ANALYZER THEREFOR    An apparatus to automatically determine on-line, the shive content and shive size distribution of a wood pulp:          The apparatus includes a line having an inlet and outlet, and a plug for closing the line.  A motor and gear displaces the line with respect to the plug for defining a gap.  A transducer measures the size of the gap.  A sensor monitors impedances in the line caused by the accumulation of oversized shives at the gap.  Responsive to the sensor is a device for releasing the impedance by rapidly enlarging the gap, each release during a time period being registered by a counter.  A controller correlates each of the counts with the corresponding size of gap to establish the content and size distribution of the shives.  The method comprises passing through a measured variable gap a measured flow of wood pulp, measuring the pressure increase caused by the shives exceeding the size of the gap, enlarging the gap to allow the passage of all shives when the pressure has reached a predetermined level, repeating the same while automatically varying the size of the gap and registering over time the number of occurrences the gap is enlarged for each gap size and correlating the number of occurrences and the sizes of gap to automatically determine on-line the shive content and shive size distribution.

Abstract: ABSTRACT OF THE DISCLOSURE    A digital recording medium formed of a thermoplastic substrate having a regular array of microscopic optically-alterable mirrors each supported by a mesa protecting from one surface.  The parallel rows of the mirrors are the same distance apart as the mirrors in each row.  A layer of transparent plastic over the mirrors provides dust pro-tection.  The medium can be formed from a single transparent thermoplastic substrate with an array of indentations in a first surface.  The bottom of each indentation is coated with a reflective material.  When viewed from the opposite surface of the substrate, the indentations become mesas.    Recording is by exposure to a laser beam that reduces the reflectivity of selected mirrors.  After exposure to the recording laser beam, the mirrors retain enough reflectivity to be distinguishable from the intervening valleys.  The mirrors serve as timing and tracking markers prior to and during recording, and during read-out. The area and location of each information bit is determined prior to recording: not as a result of the recording process. The mirrors are scanned diagonally across the rows that make up the array. Scanning is accomplished by reciprocating movement of the medium.   6b-1

Abstract: ABSTRACT OF THE DISCLOSURE    The invention concerns a delivery device for continuous threads having a storage member to which the thread is fed in circumferential direction and from which it is withdrawn overhead and on which a given adjustable number of thread turns is stored as storage quantity between feed point and withdrawal point, a light monitor which scans the circumferential surface of the storage member and controls the rotary drive for the feeding of the thread being provided in order to determine the number of thread turns.          In order to make the thread tension uniform upon the applying of the thread to the storage member and in order to reduce the stresses acting on the braking device, it is proposed that the speed of rotation of the rotary drive be controlled as a function of the light intensity (amount of light) measured on the light monitor receiver.

Abstract: Abstract Arc-over in the cathode ray tube of a digital television receiver produces a large current pulse which, when it discharges via the chassis ground, disrupts the reference ground potentials of other circuitry coupled to the chassis ground.  The affected circuitry includes digital data storage elements which may experience random state changes caused by the fluctuating ground potential.          The CRT arc-over condition is detected by circuitry which applies a pulse to the reset terminal of the microprocessor, causing it to restore the potentially corrupted data in the data storage elements using preset data stored in a less volatile programmable read only memory.

Abstract: The post profile possesses two profile legs extending at a distance from one another in the profile longitudinal direction and inter-connected by a web. The profile legs are joined to the web via spring portions. The spring portions are hairpin-like material strips which are folded at the longitudinal edges, remote from one another, of the web on the side facing away from the free ends of the profile legs and then merge into marginal strips of the profile legs which project beyond the plane spanned by the web. On deflection of the regions, remote from the web, of the profile legs into the hollow space enclosed by the undeformed post profile, the profile legs strike the said outer longitudinal edges of the web, which then serve as stops for limiting the spring excursions of the profile legs. <IMAGE>
