Abstract: An active four-wheel steering system for motor vehicles, with steering arrangements for the front and rear wheels is described. These arrangements act as a function of driving-condition variables fed to an electronic control unit. A variable steering-lock angle ratio with respect to the front wheels is set, a first function converter of the control unit being supplied with the input signal relating to the steering-wheel angle by a steering-wheel angle sensor and with the further signal relating to the vehicle speed by a speed sensor. This function converter produces a first output signal for the lateral acceleration, which is fed as an input signal, together with the further input signal relating to the vehicle speed, to a second function converter. To allow for a change in the driving speed, the output signal relating to the lateral acceleration is fed, together with a signal derived from the change in the driving speed, to the third function converter. This input signal, calculated in the first function converter, and the input signals relating to the change in speed, calculated in the third function converter, are converted into an output signal for an additional rear-wheel steering angle, which is superposed on the output signal for the rear-wheel steering angle. The sum of these output signals is fed as steering-angle signal to the control unit for the purpose of controlling the hydraulic steering arrangement for the rear wheels. <IMAGE>

Abstract: The containers (1) are closed at the top by a removable lid (2), which is pressed by tensioning levers (3) against a seal, and have in the lower region a funnel (5) which merges into an outlet pipe. The latter is guided out in an arc shape to restrict the construction height. In the known containers, the difficulty occurs that the cleaning, especially of the funnel-shaped region, is complicated after emptying and the lid retainers are unreliable in rough transport and at risk of causing injury. A good handling of a container (1) for viscous substances can be achieved in that the outlet pipe is detachably connected to the funnel (5) by means of a flange (9, 10) in each case and bolts. In respect of the lid attachment, the good handling is achieved in that the lid has a peripheral seal in its edge region and a vertical peripheral flange which surrounds the upper edge of the container (1) with spacing and in which several slots (18) are present in the lid flange, in which slots the retaining claws (19), connected to the tensioning levers (3), engage. <IMAGE>

Abstract: A method and circuitry are disclosed for suppressing additive transient disturbances in a data channel; e.g., due to thermal transients caused by an MR transducer contacting a moving storage surface. Positive and negative envelope detectors (11, 12) each have their inputs connected to the channel, and provide respective outputs which are summed (13) and contain an envelope component and a residue component. A buffer (14) interconnects the detectors to allow both detectors (11, 12) to follow rapid positive excursions of the data channel signal. A nonlinear signal-adaptive filter (15) is connected to the summed output to further reduce the residue component. The data channel signal (or preferably the output from a delay means connected to the channel) is summed with the output from the filter. The relative amplitudes of these two outputs is set such that the resulting summed output signal is free of additive disturbances.

Abstract: Capillary zone electrophoresis systems are separated into two zones, one primarily for electro-­osmotic flow generation and the other dominated by electrophoretic effects, by the use of appropriately selected capillary materials for each region. Detection of the solute zones occurs in the electrophoretic region, minimizing or eliminating entirely the entry of the solutes into the electroosmotic region. The benefit achieved is avoidance or minimization of the adsorption of charged solutes by the capillary wall in electroosmotic flow.

Abstract: A polyarylene sulfide resin composition comprising a resin composition obtainable by polymerizing 40 to 0.1 part by weight of an unsaturated polyester and 0.01 to 30 parts by weight of a monomer having one or more ethylenic unsaturated bonds in the presence of 100 parts by weight of a composition comprising 1 to 99 wt.% of a polyarylene sulfide resin and 99 to 1 wt.% of a themopalstic polyester. Since the poly­arylene sulfide resin composition of the present invention is in a state wherein the polyarylene sulfide resin and thermoplastic polyester are uniformly mixed, the constituent components are uniformly dispersed and mixed to such a degree that the composition shows no phase separation even if it is passed through molding processes such as extrusion molding, injection molding, etc. carried out under normal conditions. Consequently, the composition of the present invention is very superior in that the adhesive property of paint film (paintability), which the conventional polyarylene sulfide resins do not have well, has been improved without a large reduction in the excellent properties of the poly­arylene sulfide resin.

Abstract: Device for testing and/or measuring a test object with a signal transmission being arranged between a movable trans­ducer/sensor (1) and stationarily located equipment, for ex­ample an electric cabinet. The transducer is in the form of a carriage or placed on/in a carriage which moves, for exam­ple backwards and forwards across a test object (2). By mounting a conductor (16) in parallel with the path of move­ment of the transducer and allowing this stationary conduc­tor to constitute a winding on a transformer ring-core (13), placed on the carriage and thus being movable along the con­ductor (16), signals can be transmitted without galvanic signal connection between the carriage and, for example, stationary equipment. A consequence of this signal transmis­sion is that the transducer (1) can move as a so-called shuttle across, for example, a hot steel strand (2) with no other means of driving than its own kinetic energy, which may, for example, be supplied by means of compressed air im­pulses when the transducer is positioned outside near the edges of the steel strand. The signal transmission can ad­vantageously be made bidirectional, and one field of appli­cation is the so-called eddy current testing, in which the signal transmission problem often constitutes a greatly lim­iting factor. In simplified terms the signal transmission device can be regarded as a transformer with a movable wind­ing, in its simplest embodiment.

Abstract: An air/fuel ratio feedback control system for an internal combustion engine sets an air/fuel ratio feedback correction coefficient on the basis of an air/fuel ratio for an air/fuel mixture introduced into a combustion chamber of the engine, to causes the air/fuel ratio to approach a set point thereof. The correction coefficient consists of a rich control proportional component P R , a lean control proportional component P L  and an integral component I. When the air/fuel ratio set by the feedback control system deviates from an initial set point (the stoichiometric value) due to deterioration of an oxygen sensor for detecting the air/fuel ratio, the feedback control system compensates for the deviation to cause the air/fuel ratio to approach the initial set point, by varying a ratio of the rich control proportional component P R  to the lean control proportional component P L  in accordance with magnitudes of rich and lean detection levels, or by correcting a balance between the rich and lean control proportional components P R  and P L  on the basis of a relationship between signal level varying speeds of the proportional components P R  and P L , a relationship between rich and lean control times, a relationship between rich and lean detection levels or the like.
