Patent EP-0205944-A2 (EP)
Inventor: STELZENMULLER WILLIAM KARL
IPC: H03M7/46
Filed: 1986-05-23
Abstract: A method is disclosed for thresholding the luminance component of color picture elements (pels) prior to compression. The method is most effective when used with discrete color images, such as documents having areas of nominally constant color. The method uses spatial information rather than histrog- ram information to threshold the image data. Each scan line is defined as having a series of pel runs. A pel is considered to be in a run if its luminance is within a certain range of an average luminance based on preceding pels. Each run may end in a transition region wherein the luminance of each pel differs from the luminance of the preceding pel by more than a predetermined amount. Where a transition region is found, a local threshold is set based on the average luminance of the preceding run and of the following pel. All pels in the transition region are assigned a luminance value equal either to the average luminance of the preceding run or the actual luminance of the following pel.

Abstract: A method for the complete inversion of magnetization by adiabatic fast passage during an NMR experiment on a sample having a selected nuclear specie with a Larmor frequency ω o . A radio-frequency magnetic field is generated with an amplitude B 1  and an instantaneous frequency ω(t) which is non-linearly swept, as a function of time, from a minimum frequency ω 1  substantially at a maximum offset frequency Δω below the Larmor frequency ω o , through the Larmorfrequency, to a maximum frequency ω h  substantially at the maximum offset frequency Δ ω  above the Larmor frequency. The non-linearly swept, monotonic RF signal is applied to the sample-being-investigated for a sweep time interval sufficient to invert the magnetization of the selected nuclear specie. The preferred sweep is a tangential function:     or ω(t) = ωo±γB 1  tan (ω s t)  
where ω s  = ayB i , y is the gyromagnetic ratio of the selected nuclear specie and O<α≤1.

Abstract: A twin-roll type continuous casting apparatus comprises a pair of rotatable drums (1, 1') and a pair of sidedams (6, 6', 7, 7') disposed on both axial ends of the drums (1, 1') so that a pool of molten steel is defined by the drums and the side dams. As the drums are rotated in counter directions, the molten steel is cooled so that the molten steel is partially solidified to form solidification shells which are then pressure-bonded to each other as they pass through the narrowest gap (4) defined between the drums (1, 1'), so that a steel sheet is formed by continuous casting. the side dam is composed of a side refractory part (6, 6') which functions to maintain the pool of molten steel and a metallic member (7, 7') which supports the side refractory part and which serves as a cooling plate for cooling the steel. The side refactory part (6, 6') is projected inwardly of the pool from the metallic member and arranged so that the lower end thereof is positioned in the vicinity of a point where the pressure-bonding of the solidification shells is commenced, the point being lacated above the narrowest gap (4) defined between the drums (1, 1').

Abstract: An essentially self-contained mobile tube cleaning machine (10) which is remotely operable so that there is no need for operating personnel to be in close proximity to cleaning nozzles (160) or other high pressure lines during tube cleaning operations. As a consequence, significantly higher water pressures and significantly higher water flow rates can be utilized thereby not only accelerating the rate of cleaning but also the efficiency and the effectiveness of the cleaning operation. Through the provision of a nozzle head at the end of an ar­ticulatable boom (410), it is possible to adjust the loca­tion of the nozzle (160) through movement of the boom (410) in order to clean the face of a tube bundle, the shell side of a tube bundle and the interior of the tubes themselves.

Abstract: A digital data separator for a recovery apparatus of binary information recorded on magnetic media in FM or MFM comprises a measuring unit which in correspondence with a read pulse n in input, supplies in output an information representative of the actual duration of interval N between pulse n and the previous read pulse n-1, a media speed error recovery unit as to the nominal speed which corrects such duration according to a code representative of the media speed error, a "peak shift" recovery unit which depending on the peak shift of pulse n-1, determined on the basis of the temporal history of the most recent pulses n-3, n-2, n-1 and of such corrected duration supplies in output a duratipn information related to such interval and an information representative of the direction and the entity of the peak shift of the read out pulse n, and a speed error measuring unit defining a code representative of such error as the difference between the actual duration of a period constituted by a suitable number of subsequent intervals between read pulses and their nominal duration. 
     This difference is corrected as to the peak shift of the pulses defining the beginning and the end of the period and it is further "normalized" according to the nominal duration of the period. 
     The speed error code is applied to the speed error recovery unit. The nominal duration of interval N is applied in input to a logic unit generating a "window" signal and reconstructing the read pulse in a suitable phase relation with the window signal.

Abstract: The present invention relates to a control system for an engagement pin employed in a drum-type weft storage unit which is mainly employed in a jet-loom for storing the weft and for measuring the same in length. A novel control system for an engagement pin employed in a drum-type weft storage unit is provided. An engagement-time is compensated on the basis of a difference in time between a target-time later than the engagement-time of the engagement pin by a normal time-lag, to make it possible that the engagement-time is always set to be optimum in spite of the existence of variation in shuttling speed of the weft, so that is possible to keep the variation in length of the delivered weft minimum while the weft feeler is employed in place of the disengagement sensor.

Abstract: A buckle for fastening slings (16) and similar lashing-down straps. The buckle comprises a plate-like frame (12) and one pair of bars (18) which are mounted one on either side of an aperture (14) formed in the frame (12). The bars (18) are pivotally mounted and are arranged to be pivoted from an outer position to an inner position in which they abut against the frame, clamping said sling (16) to the buckle.
