Title: Alternating pressure adsorption of several differing crude gas streams - using separate adsorber groups cross connected at outlet side
Inventor: BENKMANN CHRISTIAN DIPL ING
IPC: C01B3/56
Filed: 1980-12-09
Abstract: Two or more crude gas streams of different compositions are broken down in a single adsorption plant comprising a number of adsorbers operated cyclically with pressure changing; each cycle includes an adsorption phase and a regeneration phase comprising expansion, scavenging and repressurising. For each crude gas stream there is a group of adsorbers, through which the stream is conducted and decomposed; each adsorber belongs to only one group and, at least during a stage of expansion, the expansion gas produced in an adsorber which is in the regeneration phase is conducted to another group. Used for decomposing several gas streams of different compositions. The process makes optimum use of the available adsorbers and results in high efficiency for a given size of plant. This is due to the particularly high yield of the non-adsorbed components, resulting from a more detailed breakdown of the regeneration phase into individual steps. The basic feature is that groups of adsorbers are connected together at the outlet side. One typical application includes the obtaining of hydrogen from a hydrogen-hydrocarbons mixture with steam reforming of the hydrocarbons, followed by adsorptive separation of the hydrogen produced.

Title: Exhaust flow back pressure system
Inventor: SCHMIDT MARTIN
IPC: F02M26/01
Filed: 1981-02-04
Abstract: In order to reduce the fuel consumption and the proportion of pollutant emissions in the exhaust gases in the idling and partial load range, at least one throttle element producing and controlling the necessary exhaust flow back pressure and controllable for all operating phases of the internal combustion engine is incorporated into the exhaust outlet downstream of the exhaust valve of the internal combustion engine in such a way that, depending on the charge of the internal combustion engine, an advantageous exhaust gas stratified charge is produced by means of the throttle element in order to reduce the fuel consumption and the proportion of pollutant emissions in the exhaust gases. In addition, this also permits a reduction of the idling speed of the internal combustion engine when idling, the throttle element being mechanically or vacuum-controlled, preferably by electronics, as a function of the operating phases and the speeds of the internal combustion engine.

Title: Device for the optimum angular adjustment of vehicle devices
Inventor: SHINOHARA TOSHIO
IPC: B60N2/48
Filed: 1981-09-29
Abstract: Automatic angle adjustment device for adjusting vehicle devices which are to be adjusted to an optimum angular setting with respect to a driver, for example for adjusting the degree of play of a mudguard, an interior mirror, outlet nozzles of an air-conditioning system, a loud speaker or a display device. The adjustment values, i.e. the degrees of adjustment of parts of a vehicle seat, are detected with the aid of position detectors and the optimum angles of the vehicle devices, the size of the driver or the eye position of the driver are calculated on the basis of the position signals supplied by the position detectors in order to adjust the vehicle devices automatically to the desired angular position. When the size or the eye position of the driver is calculated, the calculation of the optimum angles is also based on the calculated size or eye position.

Title: Process for manufacturing double-shell prefabricated concrete parts as prefabricated elements with window and door openings and form for carrying out this process
IPC: B28B1/00
Filed: 1981-10-26
Abstract: A process for manufacturing double-shell prefabricated concrete parts as prefabricated elements with window and door openings is described, in which, with the aid of mutually adapted forms for the shells, an opening is in each case cast around in these, there being cast on one shell by means of a divided hollow form a concrete inner face which, during the last production stage, is immersed by a given amount into the still soft second shell, and the second shell setting in this positional relationship to the first shell. There is thus created an opening inner face consisting of concrete which bridges the two shells in a circumferential and closed manner in the region of the door or window openings. The forms necessary for manufacturing these prefabricated elements can be reused so that manufacture of such elements becomes economical. Moreover, with the prefabricated concrete part according to the invention, the concrete casting pressure, which thus far rested on the window frame during filling of the shell cavity, is absorbed by the solid concrete inner face so that it is possible to manufacture a qualitatively superior window and door recess, into which a window can now be cast even as early as during manufacture of a shell.

Patent DE-3146088-A1 (DE)
Title: Plate heat exchanger
Inventor: DIETZ RAINER ING GRAD
IPC: F28F3/12
Filed: 1981-11-20
Abstract: A plate heat exchanger has a stack of partitions, which are arranged at a distance from one another and form between themselves flow channels for the fluids participating in the heat exchange. If a fluid under high pressure is to be guided through such a plate heat exchanger, it is necessary for the partitions to have an appropriately thick-walled and stable design. However, the result of this is that the transmission of heat through the partitions is very poor. Consequently, according to the invention at least one of the flow channels is constructed to be more resistant to pressure than the remaining flow channels, and serves to conduct the highly pressurised fluid.

Title: Fault current trip device for DC, pulse and AC fault currents
Inventor: ULLMANN BERND DIPL ING
IPC: H02H3/33
Filed: 1982-02-16
Abstract: A fault current trip device for DC, pulse and AC fault currents having at least one summing current transformer whose secondary winding forms the inductance of an oscillator. The object of the invention is to create a trip device which has a virtually identical tripping sensitivity for fault currents from a pure sinusoidal current to a pure DC current, without adaptive external involvement. The invention is that, if the geometric sum of the primary currents differs from the value zero, the summing current transformer influences the quality of the oscillator tuned circuit as a consequence of a change in its magnetic values, and the change in the amplitude of the oscillator output voltage resulting from this is used as a fault signal. In order to prevent voltages being induced in the oscillator circuit when AC fault currents occur, either two summing current transformers with windings in opposite senses or one summing current transformer with two magnetic circuits are provided. <IMAGE>

Title: Device for controlling the speeds of the driven wheels of a motor vehicle
IPC: B60T8/175
Filed: 1982-09-16
Abstract: On a motor vehicle the speeds (nR, nL) of the driven wheels (10, 11) are compared with one another. If a predetermined difference in the speeds is exceeded, the wheel brake (14, 15) of the wheel rotating more quickly is triggered by a control unit (17) causing a differential lock to function. At the same time a sensor (24) for the lock angle of the steering wheel (23) is also provided which is likewise connected to the control unit (17). In order to prevent accidental actuation of the differential lock when cornering, the difference in speed at which the one wheel brake (14, 15) is triggered is fixed as a function of the lock angle. <IMAGE>
