Patent DE-3138579-A1 (DE)
Title: Structural component made of iron
Inventor: KAES GUENTER
IPC: F16K31/06
Filed: 1981-09-28
Abstract: The structural component proposed has a structural element (9) which is merely bonderized and a zinc-plated add-on piece (12). By drawing the zinc-plated add-on piece (12) onto the bonderized structural element (9) the latter is provided with a surface protection achieved as a result of the distant effect of zinc. When such a structural component is used as a housing (9/10) of an electromagnet (3), transfer of magnetic lines of force from a core (9) to a magnetic sleeve (10) is unimpeded and a magnetic air gap can be made very narrow because the zinc layer is omitted. <IMAGE>
Patent DE-3141068-A1 (DE)
Title: Follow-up controller for an antenna rotor
Inventor: ROTHER PETER DIPL ING
IPC: G05D3/14
Filed: 1981-10-16
Abstract: The invention relates to a follow-up controller for an antenna rotor, which is connected via only three control lines to a control unit, whose DC motor is set in motion by the setting of a rotation angle for a desired antenna direction on a variable electrical resistor which is installed in the control unit, and automatically comes to rest when a variable electrical resistor, which is followed-up by the motor, has reached the value associated with the desired antenna direction. In order to accommodate the entire electronic control device, with the exception of the followed-up resistor, in the control unit, and for precise direction setting of the rotor with as little outlay on electrical components as possible, the said follow-up controller is constructed in such a manner that, depending on the difference between two control voltages which are applied to the inputs of an operational amplifier, which difference is determined by the setting of the two variable resistors, one of two transistors connected to the outputs of the operational amplifiers is switched on and the motor is set in motion by the collector current of this transistor.

Title: Method and device for lowering the harmful-substance content after heat generators
Inventor: KREMER ROBERT
IPC: F23L7/00
Filed: 1981-11-14
Abstract: In a method and a device for lowering the harmful-substance content of the waste gases of heat generators fired with gaseous and/or liquid fuels, in particular the content of harmful nitrogen oxides is to be lowered. This is achieved in that the temperature in the combustion chamber is lowered during operation. The temperature lowering is achieved in particular by injecting water into the burner flame. The sensible heat and the condensation heat of the waste gases can be recovered in a downstream heat recovery device. At the same time, the condensation water arising during heat recovery can be used for injection into the burner flame.

Title: Actuator
Inventor: GULDE BERND DIPL ING
IPC: F16K31/126
Filed: 1982-04-24
Abstract: The invention relates to an actuator, in particular for a valve, having a spindle and a diaphragm disc fastened to the spindle. In the actuators which have become known previously, the making of the connection between the diaphragm disc and the spindle involved a comparatively large effort. Collars, shoulders and the like were created by the machining of a workpiece having a comparatively large diameter, the finished spindle then having a substantially smaller diameter overall. In order to obtain a reliable connection which can be made cost-effectively, it is proposed according to the invention that the spindle consist of a prefabricated bar having an essentially uniform diameter, that this spindle have an annular groove or the like, and that a holding element consisting of at least two parts engage in the annular groove, to which holding element the diaphragm disc is connected. <IMAGE>

Title: Method for driving an electro-optical display device and circuit arrangement for carrying out this method
Inventor: TAUER KARL DIPL ING
IPC: G09G3/18
Filed: 1982-09-21
Abstract: It is proposed to realise a two-step multiplex method with the following pulse diagram: the selected line (X1, X2) initially receives a voltage 2Ux and is subsequently applied to 0 V; both time periods are equally long. A non-selected line (X1, X2) receives the voltage Ux during the same time. The columns (Y1 to Y28) receive data pulses "zero", "one", the first of which corresponds in phase position and shape to the scanning pulse and the second of which is inverted with respect to the latter. These voltage sequences can be generated with three-level switches (4) on the line side and simple on/off switches approximately in the form of exclusive OR gates (7) upstream of the columns. The circuit is thus relatively simple and can be constructed from commercially available components. The optical contrast is hardly any weaker than in an optimised, more complex addressing system. The main area of application is multi-digit seven-segment numerical displays, in particular liquid crystal displays which are suitable for calibration.

Title: Electrical melting fuse
IPC: H01H85/08
Filed: 1983-01-22
Abstract: In electrical melting fuses having a melting conductor which has connecting ends on both sides of its strip-shaped, flat response region, which is constructed with constriction points, which connecting ends are electrically connected to the contact elements of the fuse, the power loss in operation can be significantly reduced without any detrimental effect on the response characteristic in that at least one of the connecting ends is constructed thickened, by enlarging the conductor cross-section, but without significantly enlarging the conductor surface and the melting conductor regions with respect to the strip-shaped response region. This thickened construction can be carried out by: folding together a blank which is enlarged in the region of the connecting end or electrically conductively applying an additional conductor strip onto the connecting end, or using a conductor strip which is pre-profiled in a thickened manner in the region of the connecting end, or providing connecting ends in the form of round wires or pins, the strip-shaped, flat response region being capable of being formed in a blank in the form of a wire or pin by pressing together between the connecting ends which remain in the original profile.
