Patent DE-4335917-A1 (DE)
Title: Device for creating an oscillating movement, such as for ringing a bell - has motor with static relay and reversing relay in two phases, plus relay in third phase
Inventor: BODET PIERRE
IPC: H02P23/00
Filed: 1993-10-21
Abstract: A device for imparting an oscillating movement (e.g. for a bell) has an AC-fed motor with a control system comprising two optical or magnetic sensors for position, direction and speed inputting to a microprocessor, connected to two reversing relays for the motor. The motor is three-phase, and two phases each have a static thyristor relay and a reversing relay. There is a relay in the third phase which is always opened at the instant when the reversing relays in the other phases come into operation, thereby eliminating inductive voltages at the terminals of the static relays which would otherwise cause sparking at the reversing relay terminals. The coils of the reversing relays are in series. ADVANTAGE- No arcing at terminals of relays.

Title: Method and device for bringing about gentle and correctly timed deceleration or stopping with an automatic train control system
Inventor: KUBOTA KIYOTO
IPC: B61L27/00
Filed: 1994-03-21
Abstract: A method and a device relate to a high speed and simultaneously gentle deceleration or stopping of a train by means of a control using a system for automatic train control (ATC). According to the automatic train control, a permissible maximum speed in the form of a "condition of automatic train control" is provided for the actuation of the brake system of a train if this speed is exceeded. If a change in the speed of the train is necessary, a central control determines a feed-in section for which the condition of automatic train control is modified. Then, a message relating to the change in the condition of the automatic train control is fed to a substation which corresponds to the specific feed-in section. The message contains the imminent reduction in speed. As a function of this, the substation decelerates the train without using the automatic train control brake system provided in the train. If the train is subsequently braked to a sufficient degree that the change in the condition of the automatic train control does not bring about any activation of the brake system of the automatic train control, the change in the condition of the automatic train control has been effected.

IPC: F23G5/027
Filed: 1994-06-10
Abstract: The refuse treatment process involves burning some refuse in a smouldering drum (10), producing smoulder gas and smouldering residue. A carbon-rich fraction is separated from the smouldering residue. At least part of this is intended as fuel for a support flame to burn another part of the refuse. This combustion takes place in a revolving tubular furnace (2). The smoulder gas and the carbon-rich fraction of the residue not needed for the support flame can be burnt in a post-combustion chamber (3) of the furnace. A quite small tubular furnace will suffice. No external energy is required to heat it. <IMAGE>

Title: Electrophoretic process for the separation of biopolymers
Inventor: SCHUMACHER JUERGEN
IPC: G01N27/26
Filed: 1985-07-25
Abstract: The process for the separation of electrically charged biopolymers utilizes the property of these molecules to present difference structures in different conditions and consequently different electrophoretic mobilities. The separation takes place in at least two directions in a single gel matrix, in conditions which are now stabilizing, now distabilizing, as to the structure. It has been shown that by the use of said technique, nucleic acids such as viroid RNA may be very rapidly evidenced, without ambiguity and without previous washing of tissue extracts with a health-detrimental extraction medium. In view of the sensitivity of the method in relation to the silver coloration, it is possible not to use molecular hybridation techniques with radioactive isotopes. The test is thus appropriate as a routine process in series analysis.

Title: Process for operating a power switch
Inventor: PFLAUM ECKARD
IPC: H01H33/34
Filed: 1991-06-04
Abstract: In order to make synchronous switching possible in the operation of a high-voltage power switch fitted with a hydraulic drive by means of a triggering control device (16), the available hydraulic pressure in the hydraulic drive system (2) is used as a correction factor to determine the triggering delay. The hydraulic pressure in the hydraulic system repeatedly falls within a pump cycle (12) to a minimum, to be brought up to the maximum again by pumping in hydraulic fluid from a tank (7). As the pressure drop occurs according to a certain time function, it is possible to calculate the hydraulic pressure from the time elapsed since the beginning of the cycle. This obviates the need for continuous measurement of the hydraulic pressure. The invention may be advantageously used in synchronous switches.
