Abstract: An oil supply system for an internal combustion engine includes an oil pump, a heat exchanger, an oil feed line and two oil outlet lines, for conveying the oil from the oil pump through the oil feed line to the heat exchanger and from the latter through the two oil outlet lines. In a system of this type, there is provision for the internal combustion engine to be configured as a piston engine and for the heat exchanger to be configured as a water/oil heat exchanger, and for one oil outlet line to be connected to oil spray nozzles of the piston engine and for the other oil outlet line to be connected to a main oil line of the piston engine. An oil supply system of this type is distinguished by its simple design and functionality, and permits optimum cooling and lubrication of the relevant components of the engine.

Abstract: A method and device for the pretreatment of polymer surfaces of components to be painted. At least one polymer surface of at least one component is preheated to a temperature that minimizes condensation on the component when the component is subsequently cleaned inside a pretreatment cell and then treated with an oxidizing flame. The cleaning of the polymer surface as well as the treatment of the polymer surface with an oxidizing flame are performed inside the same pretreatment cell.

Abstract: Self-pumping spring and damper unit (13) with automatically activated ride level control system for chassis of vehicles having a pump which is driven as a result of the distance between the articulation points (14, 15) which changes as a result of the spring compression and spring extension of the vehicle, wherein an elastic connecting element (35) is arranged between at least one pump part (33) and the associated articulation point (14) in such a way that it at least partially elastically compensates the distance between the pump parts (32, 33) which changes when the vehicle experiences spring compression and spring extension.

Abstract: An air spring and shock absorber unit for bicycles or motorbikes includes operator control elements which are accessible from the outside and are disposed on an outer surface of the air spring and shock absorber unit. The operator control elements are disposed so as to be rotatable about a common axis and relative to a position of articulation points.

Abstract: Disclosed is a ride level control system for a motor vehicle composed of a pneumatic spring (1), a connecting line (3) which connects the pneumatic spring (1) to an atmospheric port (5), and a first valve (2) which, in a first switched state, disconnects the connecting line (3) and, in a second switched state, clears it, wherein a vessel (4) is arranged in the connecting line (3) between the first valve (2) and the atmospheric port (5).

Abstract: An air spring has three air spring spaces (1, 2, 3). the first and the third space increase and decrease in the same direction, while the second space increases when the other two decrease and vice versa. Connectin channels(14) between the first and the second space as well as between the first and the third space are provided with adjustable restrictors (13, 13’) to control the air flow between the chambers.

Abstract: A hierarchical QAM system allows the transmission of different sources by embedding the relative constellation points. A QAM transmitting system, includes a source of a level 1 and a level 2 data stream, each data stream carrying successive symbols. A hierarchical QAM transmitter, coupled to the level 1 and level 2 data stream source, generates a hierarchical QAM signal in which a level 1 symbol is represented by a data point in one of four quadrants in the I-Q plane, and a level 2 symbol is represented by the data point in one of four sub-quadrants surrounding a center point of the quadrant containing the level 1 data point. The level 2 data point is spaced away from the center point by a grouping factor set to more closely match the bit error rate performance of the level 1 and level 2 data streams.

Abstract: A OAM receiver includes a source of a received hierarchical OAM signal. The hierarchical OAM signal represents successive data points in the I-Q plane, each data point being in one of four quadrants. Circuitry, coupled to the hierarchical OAM signal source, calculates the location in the I-Q plane of the center-of-gravity of successive received data points in a quadrant. A level 1 decoder is responsive to a received data point and detects the quadrant in the I-Q plane of a received data point. Further circuitry, coupled to the hierarchical OAM signal source and responsive to the calculating circuitry, translates the received data point in the I-Q plane such that the center-of-gravity of the detected quadrant is translated to the origin of the I-Q plane. A level 2 decoder is then responsive to the translated data point for detecting the quadrant of the translated data point.

Abstract: Generic spring/damper units are either too big or require too much mounting space or have only relatively small spring/damper compartments and are therefore not sufficiently efficient. To improve the ratio between the overall size of a spring/damper unit and the size of the damper or spring/damper compartments of the spring/damper unit, the overflow throttles (21, 22) are arranged in the cylinder housing (1) between the damper compartment (10) that is increased in size during spring compression and the spring compartment (17) that is reduced in size during spring compression, thereby reducing the dimensions of the separating piston (6) and the piston rod (7) and making the overflow throttles (21, 22) more accessible from the exterior.

Abstract: A hierarchical QAM system allows the transmission of different sources by embedding the relative constellation points. At the transmitter the constellations generated by the different sources are remapped by a grey coder and then combined. At the receiver, the different source data are decoded by using a corresponding grey code demapper.
