Patent DE-3732869-A1 (DE)
Title: Power unit on trailers for electric cars
Inventor: KINDLER ADOLF DIPL ING
IPC: B60L50/15
Filed: 1987-09-30
Abstract: For the sake of cleaner air in towns, it would be desirable to equip a relatively large number of motor vehicles with an electric drive in order to reduce the effects of exhaust gases. Most motor vehicles are used for in-town commuting, that is to say for travelling from and to the driver's place of work and electric cars would be particularly suitable for this distance. However, since these motor vehicles should also be available for, for example, holiday trips, these vehicles cannot be replaced by electric cars with a strictly limited range. In order to compensate for this disadvantage of electric cars, it is proposed to provide the electric cars with a trailer for the long-distance trips which people wish to make, on which trailer a suitable power generator which is driven for example by an internal combustion engine is mounted.

Title: Circuit arrangement for protecting the electrical power supply to installations or apparatuses
Inventor: SUTTNER NORBERT DIPL ING
IPC: H02J9/06
Filed: 1987-11-24
Abstract: The invention relates to a circuit arrangement for protecting installations or apparatuses which are supplied from the supply network against a temporary power cut, and is intended for those installations in which at least individual installation parts can be switched on and off by hand. In this case, the circuit arrangement consists in a manner known per se of an electrical power supply installation (1) which is formed from a rectifier (2), rechargeable batteries (3) and an invertor (4). In order to make derating of the electrical power supply installation (1) to cope with switching-on surges superfluous, the individual apparatuses (9, 11) are switched on, according to the invention, via a zero-voltage switch (8, 10). In this way, it is sufficient to dimension the electrical power supply installation on the basis of the average rated load and not on the basis of the overcurrents which occur. <IMAGE>

Title: Process for cleaning and degreasing of material to be treated with solvents
Inventor: FUERST WERNER
IPC: B08B3/00
Filed: 1988-07-09
Abstract: In the cleaning and degreasing of material to be treated which is treated with solvents in a closed treatment chamber and then dried with dry heated air, the solvent-enriched air from the treatment chamber is cooled in a refrigerant cooler with condensation of the solvent and returned to the treatment chamber after heating, while the condensed solvent is recirculated for the next treatment. To decrease the heat requirement and the cooling power, the solvent-containing air from the treatment chamber is precooled by the clean air leaving the cooler and only then passed into the cooler, while the clean air preheated in such a way is heated to drying temperature in a condenser, in which at the same time the solvent vapour is condensed during the drying phase with a bypass of the treatment chamber and the condensate is fed to the recirculated solvent, while the clean air heated in such a way is fed to the treatment chamber as drying air.

Title: Circuit arrangement for supplying an electrical load from an AC voltage mains
Inventor: KAHLEN HANS PROF DR ING
IPC: H02M3/337
Filed: 1988-09-08
Abstract: In the case of known circuit arrangements for supplying a load from an AC voltage mains with sinusoidal current drain, relatively high losses occur owing to double conversion, namely in a step-up-converter arrangement and subsequently in an inverter. The object of the invention is therefore to disclose a circuit arrangement having improved efficiency. The solution according to the invention avoids a second conversion of the energy by carrying out a transformation of the energy from the step-up-converter arrangement into the load circuit. For this purpose, starting with a dual converter arrangement with balance coil, the balance coil is formed by the primary winding (19) of a transformer (18), the secondary winding (20) of which supplies the load circuit with the consumer (22). The circuit arrangement can be used in power supply devices and charging devices. <IMAGE>

Patent DE-3904300-A1 (DE)
Title: Safety barrier post
IPC: E01F13/02
Filed: 1989-02-14
Abstract: The safety barrier post for building sites and other prohibited areas consists of a support with a frame at its upper end, the frame being closed at the top. The support can be a driving-in bar for loose ground or a stand for firm ground. Transverse barrier means (in beam form: barriers made of wood or sheet steel; barrier bands, barrier chains or lines) can be introduced into the frame from below or from the side, or are fixed to the frame. The holding frame which is closed at the top prevents injuries, such as those which can occur in the case of known barrier posts. Barrier posts of the prior art are, without exception, constructed in the manner of forks with upwardly directed prongs or supporting arms. Typical is the so-called Neptune's hook with upwardly projecting trident-like points. Falling pedestrians or cyclists may skewer themselves or break bones, since the prongs act as bone-breaking bars. The safety barrier post sets new standards for a barrier post which is no longer liable to cause injury.

Title: Arrangement for the track guidance of a vehicle over passive guiding means
Inventor: GOETTING JUN HANS-HEINRICH DIP
IPC: G05D1/02
Filed: 1989-05-23
Abstract: For the track guidance of vehicles, sheet-metal strips or other electrically and/or magnetically conducting materials are suited as passive guiding means. Via sensors, the deviation can be established. As sensors coils are often used which detect the field alteration caused by the guiding means. The field is generated by a generator via an antenna. The invention makes possible track guidance using only one sensor. In an advantageous way, the reference signal for the phase position is picked off from the transmitter. The sensor is mounted in such a way that it is compensated in the central position. In the case of a deviation from the central position over the guiding means, a signal is generated which is a measure of the magnitude of the offset. The phase position of this offset signal to this reference signal indicates the direction. Equipment for the control of vehicles.
