Abstract: A process is proposed, in which the air/permanent gas mixture (crude medium) is passed to a first gas separation membrane and is separated into a gas stream enriched in (permeate) organic compounds and a gas stream depleted of (retentate) organic compounds, in which the organic compounds are recovered from the enriched gas stream passed over a recovery apparatus. In the process the pressure of the primary air/permanent gas mixture is increased prior to entry into the first gas separation membrane and the pressure of the enriched gas stream is reduced after exit from the first gas separation membrane and the depleted gas stream leaving the gas separation membrane is released into the surroundings, a gas stream leaving the recovery apparatus being returned to the air/permanent gas mixture, after the pressure of this has been increased.

Abstract: The subject of the invention is a heater preferably designed as a tiled stove, which makes possible on the one hand the production of hot air for room heating and on the other hand the production of hot water. To this end, the heater contains a heating chamber (3) for combustion of fuel as primary heat source and a heat exchanger (1) which can be supplied with water to be heated and, via a blower (2), with hot air obtained by means of the heating chamber (3). According to the invention, to ensure on the one hand a high degree of efficiency for the primary heat utilisation and on the other hand a heat accumulation-free operation, there is provided a common housing (12) for two hot air circuits (I and II) which are in heat exchange with one another in the housing (12) and can be interconnected directly via a flap system (8, 9) which opens and closes depending on the operating state of the blower (2), the first hot air circuit (I) surrounding the heating chamber (3) and containing the heat exchanger (1), while the second hot air circuit (II) receives air to be heated from the environment via an inlet (14) and can give off hot air to the environment via an outlet (7). <IMAGE>

Abstract: In known folding machines, which collect the articles trimmed after the first longitudinal fold at a collecting cylinder and subsequently pass them by means of a transport device 2 to a second longitudinal folding apparatus, the collected articles lying on top of one another are perforated at the level of the following second longitudinal fold to secure their position relative to one another. For this purpose, a transfer cylinder of a substantial diameter is arranged downstream from the collecting cylinder, which transfer cylinder has an annular perforating groove, with which a perforating blade of a perforating cylinder applied to the transfer cylinder interacts. Despite the large diameter of the transfer cylinder, the perforation undertaken in the curvature of said diameter tends to come apart when the articles are straightened on the subsequent belt line. The perforating cylinder and the second longitudinal folding apparatus each have to be adjusted individually when being set to the centre of the article, which is troublesome. 
<??>Due to the fitting of the collecting cylinder with lifting fingers (14) and the displacement of the perforating blade cylinder (22) and the cylinder (23) with the annular perforating groove into the horizontally arranged system of band guides (7, 17, 24, 25, 26, 27, 28), a transfer cylinder can be omitted completely. The perforation takes place in the straightened position; the cylinder with the annular perforating groove has a very small diameter. By the arrangement of the band guide and drive cylinders (18, 19, 20, 21) and of the pair of perforating cylinders (22, 23), together with the second longitudinal folding apparatus (29, 30), in an auxiliary frame (34), which is movable perpendicular to the second longitudinal fold, they can be adjusted synchronously.

Abstract: A power steering system includes a motor (13) for power assisting the steering motion induced by an operator. The motor (13) is coupled to a steering rack (6) via a speed reduction gear (15,16,18) and first and second clutches (14,17). The operation of the motor (13) and the clutches (14,17) are controlled by signals supplied from a control unit (109). The system includes a torque sensor (3), a vehicle speed sensor (10), a deceleration sensor (119), an acceleration sensor (120), a power sensor (121), and a battery sensor (122). These sensors supply the control unit (109) with signals thereby enabling the system to control operation of the motor (13), and hence the power steering operation, in dependence upon the acceleration or deceleration of the vehicle, the steering torque applied to the wheel (1) by an operator, the vehicle speed, the battery power and the power supplied by an alternator. A vehicle height sensor (19) may also be included to enable control of the power steering in dependence upon the vehicle height. The control of the steering in dependence upon signals from these sensors enables the system to allow   improved travel stability of the vehicle, particularly when the vehicle is travelling over uneven roads or when insufficient power is available from the battery (11) or alternator.

Abstract: A high bandwidth RF sampler using equivalent time sampling comprising an RF coplanar waveguide integrated with sampling diodes on a gallium arsenide substrate. A monolithic, integrated nonlinear transmission line is integrated on the same substrate to receive sample pulses. These pulses are reshaped by the nonlinear transmission line to have a very fast edge. This edge is differentiated by a shunt inductance of a short circuit termination of a slot line portion of the RF signal coplanar waveguide. The resulting delta function sample pulses cause the sample diodes and integrated capacitors to develop an intermediate output frequency which is a replica of the RF signal at a lower frequency and no voltage conversion loss. RF signals of up to 300 Ghz can be sampled using this circuit.

Abstract: A waveform encoder/decoder comprising an encoder having an input (2) for an audio signal to be encoded, and an output (3) whereby the digitally encoded signal is passed to a transmission link (not shown) and thence to a corresponding decoder (also not shown). The encoder comprises detectors (25,26) for monitoring the digital output signal for slope overload and idle pattern respectively and setting a corresponding value in a state machine (27). The value stored in the state machine (27) is used to control a pulse width generator (28) which in turn controls the enable time of a tri-­state gate (23) connected in the feedback path from the output (3) back to the input. An R.C. filter (22) is used to reconstruct the digital output from gate (22) to form an estimate of the audio input signal, and this estimated signal is compared with the actual input signal in a comparator (10). A D-type flip-flop (11) is used to digitise the output from comparator (10) to generate the signal to be output to the transmission link. The circuit, being fully digital, ensures improved repeatability and is particularly convenient and low in cost.

Abstract: An electric power steering apparatus for an automotive vehicle has an interrupter (25) which cuts off the power to a drive motor (14) when a dangerous situation is detected. In one form of the invention, the interrupter (25) cuts off power to the drive motor when a ground fault sensor (27) detects a ground fault of a motor driver (10) and there is disagreement between a directional drive signal to the drive motor and the direction of torque applied to the steering wheel by the driver.

In a third form of the invention, the interrupter (25) cuts off power when the motor current exceeds a prescribed level and disagreement of directional signals is detected.
