Title: Circuit arrangement for switching lamps over in an interruption-free manner, especially in the display panel of a car radio
Inventor: FISCHELMAYER HEINRICH
IPC: H05B39/02
Filed: 1985-02-14
Abstract: A circuit arrangement is described for switching lamps over in an interruption-free manner, especially in the display panel of a car radio, which circuit arrangement makes it possible to display a new state (for example frequency and/or colour) immediately in a simple but effective and power-saving manner. This is achieved in that a preheating voltage is supplied to the lamps which are not activated in each case, via a controllable switching stage which is connected to a driver stage, while the other lamps are just activated, and in that, furthermore, the lamps are connected in series. In consequence, the lamps are switched over in an interruption-free manner, especially display illuminations for frequency and/or colour, in conjunction with wavebands which are set on a car radio, no heating problems occurring, either, as a result of the use of only one circuit. In addition, the voltage of the illumination device which is not switched on completely is used for the second illumination device. As a result of the immediate illumination of the new state, the car driver is diverted from the traffic situation for only a very brief time and does not adversely affect road safety.

Title: Process for coating and impregnating electrical components with synthetic resins
Inventor: KNECHT ARMIN DIPL ING
IPC: C09D5/46
Filed: 1985-11-15
Abstract: A process is proposed which serves for coating and impregnating rotationally symmetric electrical components, which have wire coils, such as rotors or stators, with synthetic resins. The synthetic resins used can be both powder coatings and reactive liquid resins. The electrical component, after a preceding heating, is dipped into the impregnating agent to the extent that only the wire coils are reached by the impregnating agent and the component is simultaneously rotated. As a result it is achieved that the coating only proceeds where it is necessary, that is on the armature stampings having the wire coils, but that the commutator with its bars and the axle are not coated. It is particularly advantageous for the powder coating if the heating of the component is carried out by passing a current through the wire coils so that the sections of the component to be coated heat up to the desired temperature by this resistive heating. When reactive liquid resin is used, it has proved to be more expedient to carry out the heating in an oven or inductively.
Patent DE-3542427-A1 (DE)
Title: Socketed-pipe connection
Inventor: MUECHER HORST A
IPC: B28B21/56
Filed: 1985-11-30
Abstract: A socketed-pipe connection consists of a socket, a tip end and a sealing ring, which is preinstalled on the socket of the one pipe and consists of elastomeric material. In the final installed position, the sealing part of the sealing ring seals the socket gap, which is situated between the two pipes, elastically. After the pre-installation, the retaining part (which is situated on the axially front end of the sealing part) is inserted into an annular groove which is open towards the end wall of the socket or obliquely towards the socket inner edge and already exists on the socket at the start of pre-installation. The axial wall projection (which is situated between the annular groove and the socket inner edge or inner wall of the socket) has a stiffness in the radial direction which allows it to absorb the radial tensile forces which originate from the sealing ring, on the wall projection during and possibly after installation. The pre-installation of the sealing ring on the socket does not need to take place until shortly before dispatch or laying of the pipes, so that reductions in the quality of the seal caused by excessively long storage in the open air are avoided.

Title: Device for the exchange of substances between two flowing liquids
Inventor: ODEHNAL ERVIN DIPL ING
IPC: A61M1/36
Filed: 1986-06-18
Abstract: The invention relates to a device for the exchange of substances between two flowing liquids, e.g. blood and dialysate. The device is especially suitable for haemodialysis, but also for dialysis, filtration, ultrafiltration and heat exchange. The invention resides in the creation of an optimised membrane holder. This optimisation resides in the fact that such a geometrical arrangement of the housing and the membrane holder at the given mechanical parameters of the membrane is found that little air is incorporated in the sieve meshes and there are only low pressure drops on the blood and dialysate side, and that optimum leading array of the two functional liquids on the membrane surface and hence maximum efficiency are ensured.
Patent DE-3622156-A1 (DE)
Title: Digital regulator for adjustable state variables
Inventor: LAMBERTI HANS
IPC: G05D23/19
Filed: 1986-07-02
Abstract: A digital regulator for state variables, especially for heaters with different modes of operation, has an adjustment device for the required temperature values and for other state variables for two or more modes of operation. The required temperature values can be increased or reduced by depressing one of the two keys of a pair of keys and then appear in a display field. In order to be able to carry out such an adjustment of the required value, a corresponding shift-key must be depressed, which carries out the selection of the desired mode of operation. However, depressing the shift-key is not necessary for a selected mode of operation, for example the day program. On the contrary, the adjustment of the required value in this selected mode of operation is already selected automatically by depressing one of the two keys of the pair of keys. The same applies when other state variables are adjusted by the digital regulator to a prespecified adjustable required value in two or more modes of operation.
