Abstract: A hydraulic system for a mobile working machine includes a hydraulic pump, a steering valve, a steering actuator controlled by the steering valve, a first hydraulic line which extends between the hydraulic pump and the steering valve, and a hydraulic storage unit which is connected with the first hydraulic line via a second hydraulic line). So as to optimize a pressure state for the hydraulic system, a throttle connected in parallel with a check valve is located in the second hydraulic line. The check valve permits one-way fluid flow in a direction away from the hydraulic storage unit.

Abstract: The construction element (1) has a hollow body (2) which extends along a longitudinal axis (A) and has substantially rectangular cross-section, possibly with rounded corners, and at least a first (3a) and at least a second (3b) strut element, wherein the first strut element (3a) extends from a first edge of the hollow body (2) to the second edge which lies opposite it with respect to the longitudinal axis, and the second strut element (3b) extends along the other diagonal between the associated edges. The strut elements (3a, 3b) are advantageously designed and arranged such that they absorb compressive forces but not tensile forces. A semi-finished product (1a) which has the strut elements (3a, 3b) and a tubular sleeve element (4) which extends along a longitudinal axis (A) can be arranged inside the construction element (1). The hollow body (2) and the strut elements (3a, 3b) can be fabricated completely from a fiber-reinforced plastic.

The expanding walls of the chambers are disposed transversely to the bearing axis (A). The inner bearing part is segmented with respect to the longitudinal axis (A) of the bearing and includes a center main segment with bearing core and bearing body and two end segments, each having an inner ring, an outer ring, and an interposed elastomeric element forming expanding wall of a chamber. The end segments are pressed with inner ring onto axial ends of the bearing core so that the material overlaps between the elastomeric elements of the end segments and the ribs of the bearing body. The channel is formed outside of the bearing body in a channel carrier element.

Abstract: A hydraulic circuit includes a pump and at least a first, second and third actuator, supplied on demand by the pump via respective load pressure lines. Each actuator is connected to the pump by a respective control valve and supply line. A first, second and third supply priorities are assigned respectively to the first, second and third actuators. In order to safeguard priority of the actuators, and to control the supply priority levels, the supply lines of the second and third actuators are connected to each other via a connecting line, and a load pressure-controlled priority valve is arranged between the pump and the connecting line in the supply line to the third actuator. Also, a flow-reducer is placed in the supply line to the second actuator). The connecting line also includes a check valve which prohibits flow from the second supply line to the third supply line.

Abstract: A panel-type construction element comprises a substantially rectangular base panel (1), which is particularly suited, for example, for use as a covering for facade scaffolding. Numerous dimples (2) can preferably be configured on the upper face of the base panel parallel to the longer side of the panel and continuous transversal areas (3) that are devoid of dimples and that respectively run at intervals in the longitudinal direction of the base panel are configured over the entire width of the latter. In the areas (3), transversal ribs (7), which project downwards and are connected to the underside and the respective abutting areas of flange surfaces (4) provided on the underside of the base panel to project downwards from the two longer sides of the base panel. The combination of longitudinal and transversal elements permits a simple, rigid and light-weight construction element, which if configured in plastic exhibits excellent weather and corrosion-proof properties and is extremely stable.

Abstract: A method for transmission of location-specific information is described. Content transmitters are positioned at different locations and information which is specific for this location is stored in a content memory for each content transmitter. Each content transmitter transmits this location-specific information in a spatially narrowly bounded transmission area. On entering the transmission area, a mobile receiving unit receives the location-specific information, processes it further and causes it to be displayed.

Abstract: An aqueous liposome system comprises at least one phospholipid, a non-phospholipidic substance which is a bile acid or derivative thereof, and, optionally, a non-toxic organic solvent. The mass ratio of phospholipid to the non-phospholidic substance is in the range between 1:0.001 and 1:0.1. The diameter of the liposomes formed in this liposome system is in the range between 35 and 90 nm. The liposome system is stable over large periods of time, e.g., several months or years, and is highly transparent. The liposomes may be loaded with a pharmaceutically active ingredient.

Abstract: A device and method for packaging a web roll, having a longitudinal axis, with a packaging sheet. The device includes a packaging sheet dispenser which dispenses the packaging sheet to produce a body packaging by dispensing, on at least a portion of a longitudinal extent of the web roll, the packaging sheet. The packaging sheet dispenser is positioned to dispense the packaging sheet to form an acute angle between the lateral direction of the packaging sheet and the longitudinal axis.
