Abstract: A differential relay includes two apparatus (1,3) each associated with a different monitoring point on the line (5) being protected by the relay. Each apparatus includes means for deriving digital data representative of the current monitored at the respective point, at time intervals defined by a clock within the apparatus. The two points are linked by a digital data communication channel (7), and information transmitted between the two points is used to compute digital data for the two points at substantially the same time, from digital data derived at different instants at the two points.

Abstract: A preloaded check valve disposed in a valve body (1) between an ink reservoir (3) and a printhead (11) has a valve opening pressure or "cracking" pressure at least sufficient to overcome the hydrostatic pressure due to gravity of ink in the reservoir (3). This prevents depriming or leakage of ink at the orifices of the orifice plate (116) forming part of the ink ejecting mechanism. Ejection of ink during printing creates a pressure differential across the valve sufficient to cause it to open and replenish the ink supply at the ink ejecting mechanism.

Abstract: Width restoring to eliminate unintended width variations in pulse width modulated data in combination with a phase lock loop allows pulse width modulated data in high density optical recordings. The width restoration is accomplished by detecting the timing relationship of the leading and trailing edges of pulses relative to expected timing for the leading and trailing edges. Expected time is derived from a phase locked loop or the original write signal. The detected timing is compared to the expected timing and the timing of the leading and trailing edge signals is corrected. Either analog or digital width correction techniques are used. Width restoration may be used while reading data or while writing the data.

Abstract: A computer-based linguistic analysis method and apparatus is disclosed which includes a compilation of a classification table for all the words in a dictionary and the compilation of a plurality of inflection pattern tables, each inflection pattern table being referenced by a particular classification number which is output from the classification table. In operation, an input word can be applied to the classification table and the corresponding classification number for the input word identified. Thereafter, the classification number can be used to point to a particular inflection pattern table having the various inflected forms for the suffix or prefix of a word. When the particular inflection pattern table has been identified by its classification number, a matching operation is carried out between the input word and the ending forms or prefix forms which appear in the inflection pattern table. For example, if the inflection pattern table contains the various ending forms for the relatives of the input word, the matching operation compares from the back of the input word toward the front, the characters of the input word with the characters which appear in the various forms of the inflection pattern table. When a successful match is achieved, then the correct grammatical form for the input word is identified. In addition, the remaining portion of the input word exclusive of the matched ending portion found in the inflection pattern table,   becomes the invariant root of the input word. The invariant root of the input word can be used to build the related forms of the input word by combining the invariant root with the various ending forms which appear in the inflection pattern table. This technique can be used to advantage in a variety of applications including standalone linguistic analysis, synonym generation, document classification and retrieval, grammar checking, parsing, and other linguistic applications. The invention can be applied to virtually any indo-European language.

Abstract: A liquid leakage detector line for detecting any leakage of a liquid such as sulfuric acid or strong alkali from a transportation pipe line or storage tank comprises a pair of wiry electrodes each including a conductor (2) covered with an insulating layer (4) made of a macromolecular material inclu­ding an ester bond, the electrodes being disposed substantial­ly in parallel with each other, and a liquid-absorbent materi­al (3) covering these electrodes. The liquid-absorbent materi­al (3) may be a braided body layer made of a liquid-absorbent yarn which is disposed outside of the pair of wiry electrodes, or may be a braided body layer disposed at the outer periphery of each of the wiry electrodes. If a sulfuric acid or alkali liquid leaks, the liquid-absorbent material (3) covering the electrodes will absorb such leakage liquid which will cause the insulator layers to dissolve to short-circuit the conduc­tors (2). The insulation resistance between the conductors (2) is measured from one end of the detector line. The resultant decrease in the insulation resistance will be detected as a liquid leakage.

Abstract: A continuously variable belt-driven transmission includes a hydraulic torque converter (10), a variable diameter displaceable input pulley (14), a variable diameter displaceable output pulley (16), forward and reverse planetary gearing, a differential mechanism (20) and half shafts driven from the differential mechanism. A slipping lockup clutch (42) is hydraulically actuated to connect and disconnect selectively the impeller (26) and turbine (28) of the torque converter. The radial position of the drive belt that engages the input and output pulleys (14,16) is determined by selectively pressurizing and venting a cylinder (58) to move displaceable sheaves (52) of a pulley. Hydraulically actuated clutches are selectively engageable to produce forward drive or reverse drive from the output pulley (16) to the differential mechanism. Various sensors produce electric signals as input to a microprocessor (172) indicate the position of the engine throttle, the magnitude of engine speed, primary pulley speed, secondary pulley speed, converter lockup clutch pressure, belt load pressure, line pressure and the position of a PRNDL gear selector (182). A valve body (174) hydraulically actuates, in accordance with the output produced by the computer, the forward clutch (118), the reverse clutch (120), the torque converter lockup clutch (42) and the displaceable sheaves (52) of the input pulley (14) and output pulley (16). An electronic feedback system controls the slip, engagement and disengagement of the torque converter lockup clutch (42).

Abstract: A bevel gear 15 secured on a spindle 16 is driven in rotation by a motor. On the spindle is disposed a grinding disc held by a retaining nut and the bevel gear is formed with two recesses 21 into which a plunger can be depressed. A barrier plate 27 is disposed about the spindle and is capable of a degree of lost motion with respect thereto, the plate 27 also having two slots 29 through which the plunger can extend. The leading edges 31 of the slots are raised so that depression of the plunger during use of the tool causes the plunger to engage the edges 31 thereby causing the plate to take up said lost motion and cover up the recesses 21 to prevent the plungerfrom engaging therein. Sudden stopping of the spindle and its dangerous consequences are thus avoided.

Abstract: An arc plasma generating system includes components for adjusting spacing between the cathode (20) and the anode (18). A piston (96) affixed to the cathode is slidingly positioned in a cylinder partitioning therein a first chamber (108) and a second chamber (110). The first chamber (108) is receptive of discharging cooling fluid at reduced pressure. A first valve (162) selectively infuses pressurized control fluid into the second chamber (110) such as to move the piston (96) against the reduced pressure and thereby move the cathode (20) axially in a first direction. A second valve (164) selectively discharges the control fluid from the second chamber (110) such that the reduced pressure in the first chamber (108) moves the piston (96) opposite the first direction. Telescoping tubing (144) affixed between the piston (96) and the end wall (96) of the cylinder (80) is located within the cylinder (80) and conveys cooling fluid to the cathode. A flexible electrical cable (166) connected between the cathode and a source of arc current is located within the cylinder member such as to be cooled by fluid therein.
