Abstract: The present invention describes a device and method for the determination of one or more operating features of a rail-bound vehicle. A magnetic strip is attached to the rail and provided with alternating areas with and without magnetic flux. The vehicle is equipped with a magnetic sensor which detects the alternating magnetisation areas on the magnetic strip while the vehicle moves on the rail. The output signal of the sensor is processed by a control unit, during which the speed, the location and the distance of the vehicle from a predetermined point is determined. The system can be advantageously used in various areas of industry: in arrangements for the automatic conveyance and distribution of materials, in material stacking and material conveying devices, in control devices for cranes and similar. <IMAGE>

Abstract: In a continuous-flow analysis method for determining the contents of samples (FIA) which are introduced into a carrier flow and reacted with reactants, the carrier flow feeds a reaction product which is relevant to the detection to a detector. Sample and reactant (which are preferably adjusted to each other in time) are fed to two monitored time-programmed carrier flows which are brought together via a separating layer which is semipermeable for the component to be determined and/or the reactant(s). The carrier flow containing the reaction product is then fed to the detector. In particular, a porous dialysis membrane 10-25  mu m thick having a selective pore size in the range between 0.02 and 10  mu m is used as separating layer. As contacting cell, in which the sample and reagent flows are brought into contact via a membrane, use is made, in particular, of a dialysis cell or a gas-diffusion cell. The new technique is notable for high selectivity and insensitivity to sample matrix effects. <IMAGE>

The computer system includes an instruction compounding unit located intermediate to the higher-level storage unit and the cache storage unit for analyzing the instructions and adding to each instruction a tag field which indicates whether or not that instruction may be processed in parallel with one or more neighboring instructions in the instruction stream. These tagged instructions are then stored in the cache unit. The computer system further includes a plurality of functional instruction processing units which operate in parallel with one another. The instructions supplied to these functional units are obtained from the cache storage unit. At instruction issue time, the tag fields of the instructions are examined and those tagged for parallel processing are sent to different ones of the functional units in accordance with the codings of their operation code fields.

Abstract: A method of starting a free piston combustion engine (16) is described in which the free piston unit (16) consisting of the combustion pistons and the piston rod connecting them is set in motion by alternately pressurizing the hydraulic cylinder spaces (161) of a double-acting piston and cylinder arrangement (16) whose piston or piston is or are connected to the piston rod. For this purpose pressure from a hydraulic accumulator (5) used for starting the engine is supplied as a control pressure to the check valve members (8,9) of the one way outlet check valves of the hydraulic cylinder spaces to keep those check valves closed during starting of the engine. This control pressure supplements the spring pressure supplied by springs in the check valves biasing the check valve members towards their closed positions. Simultaneously a directional valve is used to channel hydraulic fluid from the hydraulic accumulator directly to the cylinder spaces in turn, thereby bypassing the one way inlet check valves to the cylinder spaces. In this way the free piston unit is set in motion. Once the free piston has performed a predetermined number of reciprocating movements or has attained a sufficient magnitude of inertial energy the hydraulic accumulator is disconnected so that the inlet and outlet valves can perform their normal function, while simultaneously or just before or just after this moment fuel combustion is initiated to maintain the engine in operation. An electronic controller (34) responsive to signals from sensors mounted on the engine from which can be derived information about the position and speed of the free piston unit can be used to control starting and operation of the engine.
