Title: IC engine suction air storage - involves feeding suction air during compression stroke into air reservoir for use on demand
Inventor: JAUCH ERNST DIPL PHYS
IPC: F02D17/02
Filed: 1980-11-05
Abstract: The suction air storage and utilisation is intended for combustion engines, with which the cylinders can be switched off. The suction air, even from a turbocharger, is supplied into an air reservoir from the disconnected cylinder, still running with the engine, during the compression stroke. This air is supplied to the place of corresponding demand. In order to prevent flashback of the stored air, a non-return valve is mounted behind each disconnectable cylinder. The reservoir pressure is determined by the compression ratio of the cylinders. On demand the stored air can be supplied to the suction manifold via a throttle, with safeguards against reserve air flow. The throttle control depends e.g. on the reservoir pressure, the engine speed, the accelerator pedal position, the turbocharger speed etc.

Title: Circuit arrangement of a generator for charging a battery of a motor vehicle
Inventor: BARTTENBACH GERD
IPC: H02J7/14
Filed: 1981-02-11
Abstract: A generator for charging a battery of a motor vehicle, which is driven by an internal-combustion engine, has a circuit arrangement with a switch (5) in the excitation circuit of the field winding (2). When the vehicle is decelerating, the switch (5) connects the field winding (2) to the exciter source (6). When the vehicle is not decelerating, the switch (5) isolates the field winding (2) from the exciter source. The switch (5) can be connected between the field winding (2) in the rotor of the three-phase generator and the voltage regulator. The electrical switch (5) can also be monitored by an operating characterisric of the engine. This may be, for example, the pneumatic reduced pressure (vacuum pressure) in the engine induction tube. The switch (5) can thus be constructed as a reduced-pressure switch (membrane switch) whose switching state is a function of the reduced pressure in the induction pipe (14) of the engine. It can be advantageous to bridge the switch (5) by a threshold-value switch (15) which holds the exciter circuit closed in all operating conditions of the vehicle when the voltage of the battery (11) is less than a selected minimum. The circuit arrangement according to the invention is primarily used for reducing the fuel consumption which is required to drive the generator, without the generator having to be mechanically decoupled from the engine.

Patent DE-3108945-A1 (DE)
Title: Wind wheel
Inventor: BROCKMANN HEINRICH ING GRAD
IPC: F03D7/06
Filed: 1981-03-10
Abstract: The invention relates to a wind wheel based on the known, so-called Darrieus rotor, with a plurality of blade profiles arranged around a common vertical axis and also aligned vertically. In order to enable such a rotor to be started at low incident wind speeds, the position of the blade profiles relative to the wind direction must be adjustable by means of an appropriate linkage, controlled by a wind vane. Wind wheels of this type have a multiplicity of advantages over other power generating machines making use of the wind but in their speed of rotation are for the time being directly dependent on the wind speed at any particular time. In the event of a storm, that is when a certain wind speed limit is exceeded, this can lead to destruction of the wind wheel under the effect of the large centrifugal forces occurring. In order to prevent the speed of rotation of the wind wheel from increasing correspondingly when a certain wind speed limit, dependent on the design, is exceeded, a preloaded spring of corresponding dimensions is fitted in each of the rods of the adjustment linkage for the individual blade profiles, for automatic and maintenance-free braking. <IMAGE>

Title: Hydraulic control device
Inventor: HONIG ERNST-AUGUST DIPL ING
IPC: F16H61/00
Filed: 1981-03-17
Abstract: A hydraulic control device for a motor vehicle automatic transmission has a main pressure control valve for generating a main pressure varying as a function of the load condition of the engine, the control piston of which can be acted upon by an engine load-dependent, upwardly limited control pressure. In order to achieve improved adjustment of the main pressure to, for example, a parabolic torque curve of the engine, in which relatively high torques are achieved even at low throttle valve angles, it is proposed to provide a piston arrangement loaded by the control pressure with at least two active surfaces, of which, up to a predetermined mean level of the control pressure, both operate in order to transmit pressure to the control piston, and thereafter only one. For this the piston arrangement may have a first piston, designed for direct actuation of the control piston and a second piston, held concentrically and axially displaceable on the first piston, the said second piston acting on the control piston by way of a spring and coming to bear on a stop fixed to the housing when the predetermined mean control pressure level is reached. <IMAGE>

Patent DE-3119876-A1 (DE)
Title: Infrared transmitting/receiving system
Inventor: HAFNER HERBERT DIPL ING
IPC: H04B10/114
Filed: 1981-05-19
Abstract: To extend the field of application of infrared receiving systems, for example light barrier arrangements or remote control systems so that, in particular, a number of systems can be used superimposed, that is to say so that the radiating ranges of different transmitters of different systems can overlap without causing interference, the present invention creates a multiple encoding for the infrared information signals. Various possibilities for the multiple encoding are specified. The encoding is effected, for example, in such a manner that an identification is added to the information signal, for example in the form of a start code or in the form of a particular carrier frequency. It is now possible to use a number of systems, which have a completely identical structure per se, in parallel, for example by using additional start codes. In the field of space surveillance, for example, the transmitters can operate with wide radiating cones, one or more receivers then being used, for example, for each transmitter in order to achieve efficient and unobtrusive surveillance. <IMAGE>
