Title: Balancing device for rotating bodies
Inventor: KLAMT KLEMENS DR
IPC: F16F15/36
Filed: 1997-04-22
Abstract: At least two weights (6) are arranged on the running track (5), and are freely movable above the critical speed of the body or its bearing system. All weights may be held in fixing devices (11,12). The weights are stopped in fixed positions below a predetermined first rotation speed, in which the sum of their centrifugal forces on the rotation axis is equal to nil. The weights are free to move when the body is rotating above the predetermined first rotation speed. The predetermined first rotation speed corresponds approximately to the critical speed of the body or its bearing system. The weights are circular segment in shape. They are supported on springs controlling their movement in a radial direction within the running track.

Patent DE-19717588-A1 (DE)
Inventor: DZUBAN STANISLAV DIPL ING
IPC: H04W8/18
Filed: 1997-04-25
Abstract: According to the inventive method for the administration of supplementary services (SS), a subscriber self-input (SCI) is initiated in a communications terminal (MS ) by the subscriber for the supplementary service concerned. Said subscriber self-input (SCI) causes at least one structured container message (USSD-M) to be produced by the communications terminal (MS). Said container message is then sent to a memory unit (HLR) of the communications network (KN). Once it has been received by the memory unit (HLR) the container message (USSD-M) is transmitted further via an interface (SH-IF) which links the memory unit (HLR) to the service control point (SCP). The interface implemented between the memory unit and the service control point enables the container message to reach the service control unit by means of the subscriber self-input (SCI) for the additional service, for service administration.

Patent DE-19742430-A1 (DE)
Inventor: HEIN GERD DIPL PHYS
IPC: H04L25/02
Filed: 1997-09-25
Abstract: The invention relates to a data transfer system for transmitting a digital control signal (SSt) or the feedback signal (SRSt) thereof. According to the invention, said data transfer signal comprises a transmitter device (2) with a constant power source (16) and a first current switch (18), a transmission channel (4) with a maximum of four lines (8, 10, 12, 52) and a receiver device (6) with a control signal decoupling device (30). The first current switch (18) is connected to a first output of the constant power source (16) on the input side and to a forward line (8, 10) on the output side, on whose signal input (24) a control signal is located, wherein the control signal decoupling device (30) is connected to both forward lines (8, 10) on the input side and to a return line (12) on the output side, on whose signal output (38) the transmitted control signal (SSt) is located and wherein the return line (12) is connected to a ground terminal (GND<+>) of the transmitter device (2). The data of the control signal (SSt) is thus transmitted using a single current loop in a three or four line connection with no coupled grounding line. Said data transfer system displays higher interference immunity in a wider temperature range owing to the permanent flow of constant current in the current loop.

Patent DE-19744246-A1 (DE)
Title: Portable videomicroscopic observation of suspended particles in gas or liquid stream
Inventor: SUHR HAJO PROF DR
IPC: G01N15/14
Filed: 1997-10-07
Abstract: Flow in the channel ahead of the observation point, passes a sensor zone where particles are detected optically or electrically. The detector signal triggers circuitry causing image recording by the video microscope. A delay circuit is incorporated, so that the image is not taken until the particle is located in the imaging frame. An Independent claim is included for the apparatus implementing the method. The detector is a miniature condenser (7) ahead of the imaging microscope (13). On particle (5) arrival between its electrodes, resulting capacity difference produces a measurable signal pulse (8) in the condenser circuit. Preferred Features: Particle detection takes place at the focus of a light source in the flow channel. Here a flash of light is caused by particle entry into the intensely illuminated zone. A sensitive photodetector, e.g. a photomultiplier, registers and signals the event. A CCD camera processes the image signal. This is an intelligent camera, analyzing the image and characterizing the particles and their calculated parameters. No external computer is required. The result is a compact, portable and fully autonomous particle measurement apparatus. Imaging takes place on a standard video monitor, or on an integral small screen of the camera. Results of numerical analysis from the intelligent camera, are displayed on a standard monitor or a miniaturized video monitor. They can also be made available as analog signal outputs. Digitized images may also be input to external computers for further analysis and documentation. The intelligent camera can be computer controlled, from remote locations.

Title: Vehicle wheel suspension
Inventor: DOERR ERNST-LUDWIG DIPL ING
IPC: B60G17/04
Filed: 1998-03-04
Abstract: The piston/cylinder vehicle wheel suspension system has a crossing channel (14,15) link between the units, with a flow-direction dependent valve assembly (24,25) giving a generally loss-free flow between the working chambers (10,13;11,12) from each of the second chambers (11,13) to the first chambers (10,12), between the second chambers (11,13) and their equalizing vol. spaces (22,23). When each piston/cylinder unit is in a pressure working stage, where the piston is pushed in, the valves throttle the flow in the flow direction to the equalizing vol.  According to the sway motion of the vehicle, the pressure in the flow is altered so that the pressure action in one piston/cylinder unit gives a withdrawal of the piston in the other piston/cylinder unit.
