Abstract: A method of monitoring a brake system which is equipped with anti-lock control (ABS) and a system for electronic control of brake force distribution (EBV). The system includes two brake circuits in a black/white brake circuit split-up, the EBV function or control is principally released only when the vehicle deceleration exceeds a predetermined limit value (GWN). To identify a front-axle brake circuit failure, acceleration criteria, i.e., criteria responsive to the acceleration behavior of the vehicle wheels, are predetermined and monitored. Further, slip range monitoring in conjunction with acceleration range monitoring is performed.

Abstract: A hydraulic pump driven by an internal combustion engine is an externally pressurized radial piston pump, which is internally driven by an eccentric. The hydraulic pump is integrated within the cylinder head of an internal combustion engine.

Abstract: A hydraulic system with a hydraulic pump driven directly by an internal-combustion engine reduces the dimension, weight and number of component parts used in the state of the art systems while optimizing energy exploitation. A plurality of elements, one of which is a cam shaft adjusting device, are supplied with hydraulic pressure fluid by one and the same pump. A series of simplified hydraulic connections enables equivalent devices to be driven simultaneously by one or more pump circuits.

Abstract: An electrolytic process and apparatus are disclosed for regenerating separate bed ion exchange resins used to demineralize aqueous solutions, preferably softened water, without the use of additional chemicals. The cation exchanger is regenerated by applying a DC electric voltage between an anode and a cathode across the cation exchanger whereby hydrogen ions produced at the anode displace cations previously absorbed on the cation exchanger during the previous demineralization cycle. The displaced cations move towards the cathode under the influence of the electric voltage and there form a caustic solution with hydroxyl ions produced by the cathode. The cathodically generated caustic solution is then used to chemically regenerate the anion exchanger in a traditional manner. Two embodiments of the invention are disclosed, one of which is an intermittent system of demineralization and regeneration and the other is a continuously operating system.

Abstract: A method of regenerating an ion exchanger which is used to treat a solution introduced to the ion exchanger in a downward charging direction. The ion exchanger comprises a non-constrained bed of ion exchange material in the form of ion exchange granules and has a concentration profile through the ion exchange material after the solution has been introduced to the ion exchanger in the charging direction. The method in one embodiment comprises passing a regenerating solution upwardly through the non-constrained bed of ion exchange material in an intermittent pulsed flow comprising a pulse or up flow of regenerating solution, a subsequent non-flow pause time, followed by a down flow pulse in a direction opposite to the up flow.

Abstract: A suction-restricted radial piston pump is described, in particular for use with automotive vehicles. The pump delivers a flow constant over a broad speed range and involving low losses in output and generating only negligible noise. In one embodiment, a control slot (13), on the pressure side, is subdivided into several grooves (27,28) which at least in part are in communication, through check valves (32), with the pressure connection (20). An alternative embodiment provides a shape of the pressure-sided control slot in which the introducing end thereof is comparatively narrow to reduce noise at a high speed and the outlet-sided end thereof with a wider width sufficient to meet the required output. According to a third embodiment, the suction-sided slot (12) is provided with a narrow width section and a subsequent wider width section.

Abstract: A hydraulic actuating system and method comprises a pump which continuously circulates hydraulic fluid out of a reservoir into a pressure line limited to a predetermined maximum pressure by a pressure-limiting valve and a control valve connected to the pressure line controlling flow of hydraulic fluid to an operating cylinder. A clearance volume in communication with the pressure line collects compressed air entrained in the hydraulic fluid flow which upon opening of the inlet valve expands to displace a portion of the volume of flow of hydraulic fluid required for actuation of the operating cylinder.

Abstract: A hydraulic power steering system for automotive vehicles wherein the hydraulic power assistance takes place only above a predetermined steering power. A power cylinder (6) is coupled to a mechanical steering assembly, a pump (19, 36), and a control valve (12). In order to achieve safety in operation and a simple arrangement of the power steering system, a slide of a component (2) of the mechanical steering assembly is slidable with respect to the vehicle body. The slide is effected by the steering power overcoming a prestressing power, serves for the mechanical actuation of the control valve (12).

Abstract: A temperature compensated differential between electrical conductivity measurements of a filter medium during passage therethrough of liquid being treated and measurement of the liquid alone after treatment, is utilized to calculate a conductivity ratio based on a reference value reflecting a minimum electrical conductivity measurement under ion saturation conditions in an ion-exchange filter. The filter is switched from an operational mode to a regenerating mode in response to detection of a predetermined conductivity ratio corresponding to approach of the filter to a clogged condition.

Abstract: Process and apparatus adds counterions into the aqueous solution of an electrode chamber of an electrolytic desalination or demineralization unit. In the demineralization unit, oppositely charged ions are electrolytically generated within electrode chambers and defused into the stream of aqueous solution to be demineralized. In their migration in response to the application of an electric potential, the ion streams are subjected to displacement steps in cation and anion exchange masses separated by selectively permeable ion exchange membranes. A counterion-containing liquid is subjected to an electrical voltage field, separate or in conjunction with the desalination unit, and the counterions to be added are passed through a selectively permeable ion exchange membrane into the respective electrode chamber of chambers of the desalination unit.

Abstract: Process and apparatus are provided for demineralizing aqueous solutions without using regenerating chemicals. Oppositely charged ions are electrolytically generated within electrode chambers and diffused into the stream of aqueous solution to be demineralized flowing in cross-current thereto. In their migration in response to the application of an electric potential, the ion streams are subjected to displacement steps in cation and anion exchange masses separated by selectively permeable ion exchange membranes. The aqueous solution alternately passes through the cation and anion exchange masses resulting in a demineralized aqueous stream and an enriched brine stream.

Abstract: The invention refers to a process and a device for the performance of a process for the treatment of liquids, particularly for the demineralization of aqueous solutions, whereby the liquid being treated is conducted through successive chambers of treatment, wherein in a first stage of the treatment demineralization takes place by means of ion displacement and in a second stage of post-treatment by means of ion desorption the salts that are removed from the treated liquids are led into so-called brine chambers, and are washed out of these chambers into a channel or other receiver by means of a transporting liquid.
