Abstract: ABSTRACT OF THE DISCLOSURE          The present invention provides for an improved process wherein an olefin, an alcohol, or an ester, halide or ether derivative of said alcohol is reacted with car-bon monoxide in a liquid phase in the presence of a cata-lyst system that contains (a) a rhodium component, and (b) an iodine or bromine component.  By passing at least a portion of the liquid reaction mass from the reaction zone to a separation zone of substantially lower CO partial pres-sure, at least a portion of the carbonylation products, as well as unreacted carbon monoxide, inert gases, and un-reacted olefin, alcohol, or alcohol derivative are vapor-ized and can be withdrawn from the separation zone.  Pre-cipitation of the rhodium catalyst under carbon monoxide deficient conditions is prevented or retarded by addition to the system of a stabilizer which 1.  is selected from N,N,N',N'-tetramethyl-o-phenylenediamine and 2,3'-dipyridyl, or 2.  is a dibasic or polybasic carboxylic acid having the formula   wherein Yl is of the ormula (CX1X2)m in which m is 2 to 10 and wherein Y2, Y3, Y4 and Y5 are of the formula (CX1X2)n in which n is 1 to 10, and X1 and X2 are inde-pendently selected from hydrogen, a halogen, lower alkyl, aryl, hydroxyl, carboxyl, amino, hydroxy-substituted alkyl and carboxy-substituted alkyl.

Abstract: Abstract of the Disclosure The timing cam is advanced for switching purposes by the large reciprocating pawl acting on the ratchet teeth molded on the timing cam.  When the program requires a timed period during which conditions remain the same the ratchet teeth are spaced so the pawl cannot pick up the next tooth until the cam is advanced by the small pawl acting on the separate ratchet provided with small, closely spaced teeth.  This ratchet has a pinion gear driving the ring gear molded inside the timing cam.  The steps imparted to the timing cam by the small pawl and ratchet are very small and consume appreciable time - the length of time taken to position the next tooth for engagement by the large pawl being determined by the space between the large teeth.

Abstract: Abstract of the Disclosure Feedback equalization is employed for digital repeaters of transmission systems having twisted-wire pairs, in order to reduce intersymbol interference while minimizing near-end crosstalk gain.  Previously the incoming signal was selec-tively amplified at the higher frequencies in order to negate intersymbol interference, with subsequent near-end crosstalk gain.  According to the present invention the intersymbol interference element of an incoming signal is cancelled, prior to amplification in an adder by means of a compensation signal derived from the output signal of a regenerator and a retimer. An output stage serves to amplify and shape the resultant signal to a form suitable for transmission.  The compensation signal comprises the inverted output of a filtering and scaling network.

Abstract: ABSTRACT OF THE DISCLOSURE           The invention describes a novel process for the hydrogenation of hydrocarbons, with three and more carbon atoms and several double bonds or with triple bonds in monoene-containing hydrocarbon mixtures.  These compounds are selectively hyarogenated to monoenes in a practically quantitative fashion.  Before beginning the hydrogenation, a small amount of carbon monoxide and once to twice the stoichiometric quantity of hydrogen are homogeneously dissolved in the hydrocarbon mixture.  The mixture is hydrogenated as a homogeneous liquid phase on a fixed palladium catalyst under a moderately high pressure and at a moderately high temperature.  No isomerization can be found in the monoenes and no side reactions or secondary reactions occur.

Abstract: ABSTRACT OF THE DISCLOSURE    A clutch brake arrangement for farm working machinery includes a boss parallel with an output shaft extending from an engine mount, a rotary member rotatably mounted on the output shaft, and a pressure plate mounted on the boss in such a manner that it is slidable along the axial direction of the output shaft.          The plate is provided for pressing a lining plate rotatable with the rotary member.  A brake spring is resiliently disposed between the engine mount and the pressure plate.  A cam plate is provided on the boss and cam balls are arranged between the pressure plate and the cam plate.  A retaining ring holds the cam plate on the boss.  In this way, these parts can be arranged near the engine mount, whereby the length, as viewed in the axial direction of the output shaft, and hence size of the arrangement can be decreased.  Furthermore, since the movement of the operating mechanisms along the axial direction of the output shaft is slidably guided by the boss, the parallel movement thereof is made so smooth and reliable that clutch engagement and disengagement can effectively be carried out.  In one embodiment a dust cover for covering the arrangement is attached directly to the engine mount.  Between the duct cover and the pressure plate is resiliently disposed a brake spring, by which the dust cover is engaged with, and held on, the engine mount.

Abstract: A B S T R A C T:     In NMR tomography, the nuclear spins of a selected type present in a selected area of a body are selectively excited by applying first a selection gradient field and exciting thereafter the nuclear spins by a HF signal which initially effects a rotation of the nuclear spins situated in a selected plane by an angle .alpha. of less than 90°, then a rotation of all selected nuclear spins by 90° and finally again a rotation of the nuclear spins contained in the selected plane by an angle of 90° - .alpha..  As a result thereof, the nuclear spins contained in the selected area have resumed at the end of this excitation their original orientation determined by a homogeneous magnetic field, while nuclear spins located outside this area lie within a plane extending almost vertically thereto.  Thereafter, a measuring gradient field may be switched on without disturbing the orientation of the nuclear spins contained in the selected area. With the measuring gradient field switched on, the nuclear spins are now excited by a 90° pulse or usual pulse sequences to produce an induction signal. The measuring processes are carried out in pairs, with the selection gradient field applied, using different excitation signals so that the nuclear spins contained in the selected area are alternately oppositely directed which means that the induction signals generated by them are phase-shifted by 180°, whereas the nuclear spins situated outside the selected area are shifted in the same sense, so that they supply identical signals, if any.  By subtracting the induction signals gained in two successive measurements, the signals supplied by the nuclear spins situated outside the selected area are eliminated, whereas the signals supplied by the nuclear spins situated in the selected area are opposite in phase and, therefore, added up.

Abstract: REACTIVE POWER COMPENSATOR            Abstract of the Disclosure Reactive power compensators are used for capacitive or inductive reactive powers in alternating-voltage networks.  For this purpose, a capacitor is connected to an alternating-voltage network for a short time by means of a thyristor switch .  In order to reduce the voltage load on the thyristor switch, a discharge circuit is connected in parallel with the capacitor.          Via this circuit, the capacitor can discharge, after being disconnected from the alternating-voltage network, with such a speed that the voltage occurring at the thyristor switch is no greater than about 1.5 times the maximum network voltage. In the discharge circuit, a variable inductive reactive resistance is arranged.  This can be a discharge circuit choke having an iron core or the primary winding of a transformer.  When the capacitor is connected to the alternating-voltage network the discharge circuit choke is unsaturated and its reactive resistance is large (or the transformer secondary is open) so that no significant leakage current can flow via the discharge circuit.  After the capacitor is disconnected from the alternating-voltage network, the discharge circuit choke is saturated and its reactive resistance is small (or the transformer secondary is short-circuited) so that a large discharge current can flow.  No switching element is required in the discharge circuit. In order to limit the rectifier current of the thyristor switch and to change this rectifier current with time, an air choke is provided.  The maximum rectifier voltage is limited by surge dissipators of zinc oxide.

Abstract: ABSTRACT OF THE DISCLOSURE      In a method for the mathematical, digital measurement of the phase difference of two periodic or cyclic       signals U and V of the same frequency by averaging from n elementary measurements Mi, a timing signal of a much higher frequency and asynchronous with signals U and V is counted between directly succeeding zero passages of signals U and V in the same direction.          An elementary calibration Ci is performed in each cycle of U, in which an elementary measurement Mi is performed by counting the timing signals during the complete cycle of U.  An overall phase difference is determined, in that the mean value of all the elementary measurements Mi is divided by a mean value of all elementary calibrations Ci and is multiplied by the cycle.
