Title: Electromagnetically actuated, hydraulic high-speed manipulating valve
Inventor: WOBBE JENS-PETER DIPL ING
IPC: H01F7/16
Filed: 1986-03-22
Abstract: A hydraulic high-speed manipulating valve with at least one pressure-relieved cone seat valve is described, the valve body (8) of which is arranged in the central bore of a guide bush (7). The valve is actuated electromagnetically by a pot magnet, the armature (22) of which is arranged on a pin (20) of the valve body (8). The armature (22) forms a parasitic air gap (30) with an annular pole shoe (27) of the pot magnet and forms the working air gap (31) with its end face opposite the end face of the magnet core (23). The valve body (8) and its guide bush (7) are essentially free of magnetic field and can therefore be dimensioned without regard to the magnetic properties of their material. <IMAGE>

Title: Rapid-action tripping device for line protection circuit breakers
Inventor: BROICH HANS-JOSEF
IPC: H01H71/24
Filed: 1986-06-07
Abstract: In the case of the magnetic rapid-action tripping device (10) for line protection circuit breakers, the magnet yoke (11) consists of a magnet bracket (20), which is bent approximately in a U-shape, is in the form of a clip and has a base part (21) and limbs (22, 23) projecting therefrom, and of a closure plate (24) at the end, with the contact element (9) which is bent away integrally therefrom. In addition, a holding claw (25) is bent laterally out of the base part (21) of the magnet bracket (20), engages over the recess (13) for the magnetic armature (14) from the outside, and holds together the assembly formed by the magnetic armature (14), the tripping plunger (15) and the restoring spring (19), during installation on the magnet yoke (11). The rapid-action tripping device (10) thus forms a prefabricated assembly which can be handled easily, can be pushed in between supporting pins (30) or supporting tabs (31) projecting inwards from the circuit breaker housing (7), and can in this way be fixed in the circuit breaker housing (7), a corresponding abutment web (28) for the magnetic armature (14) on the circuit breaker housing (7) ensuring that, after assembly of the rapid-action tripping device (10), there is an air gap (29) between the magnetic armature (14) and the holding claw (25) in order in this way to ensure the magnetic flux during tripping of the circuit breaker. <IMAGE>

Title: Articulated trough with limited movement for chain conveyors
Inventor: ADAM UDO
IPC: B65G19/28
Filed: 1986-07-03
Abstract: Chain conveyors used in underground working and in tunnelling can be swivelled to a limited degree in particular in the transfer region when the central metal sheet and the bottom metal sheet and lateral profiles are divided in the transverse direction of the trough and together form a bamboo knot joint in which the metal sheets are designed so as to be in engagement with one another and guided past one another and, at the centre of rotation, are held together so as to be axially fixed and capable of horizontal rotation. When the side profiles are also correspondingly designed, a very stable joint is formed, which ensures that the individual parts are guided past one another practically in two circular regions so that a perfect swivelling, in particular of the discharge head of such chain conveyors, is provided. The discharge head can at the same time also be raised and lowered, namely in that a further bamboo knot joint with a vertically running axis (as an additional pivot joint) or with a horizontally running axis is arranged in the region of the central metal sheet and in that the upward or downward guides of the lateral profiles are formed so as to be arc-shaped and at the same time to overlap one another. By these means, a crossing of the chain assemblies or of the drivers is ensured, so that the discharge head can be raised or lowered by approximately 15 DEG . The swivelling joint can be realised particularly advantageously at, for example, the connection to curved channels of the rool curves or both joints at the discharge heads of delivery conveyors, via the ...

Title: Hazard warning device for reversing vehicles
Inventor: JOECKEL ULRICH DIPL ING
IPC: B60Q1/22
Filed: 1986-10-30
Abstract: A hazard warning device for reversing vehicles is described, having a digital television camera which is arranged at the rear of the vehicle and transmits a series of images during reversing to a monitor in the driver's compartment via an amplifier. The object is, with a warning device of the type mentioned at the beginning, to detect an independently moving object in the region of the camera, and to trigger an alarm device. The object of the invention is achieved in a successful manner in that, starting from a digital image scan, identical image pulses corresponding to a stationary vehicle or proportionally changing image pulses when the vehicle is reversing are fed via an amplifier to evaluation electronics, changes which deviate from the proportionality of the image pulses triggering an alarm device. This process exploits the fact that when the vehicle is stationary the contents of the image always have constant differences in brightness distributed over the width of the image. However, when a moving object penetrates the image area when the vehicle is stationary a change of brightness values deviating from the previous fixed values is brought about so that an alarm device is triggered.

Title: Method for determining the location of a transmitter and a direction-finding receiver for such a method
Inventor: SAUR HERMANN DIPL ING
IPC: G01S5/02
Filed: 1986-12-05
Abstract: The location of a transmitter can be determined by determining the direction of a wave which is reflected on an ionospheric layer, if the ionospheric data are known. Prognoses of the ionospheric data are available for this purpose, but they do not contain the irregular fluctuations of the ionospheric properties so that considerable errors in the location calculation can result from the deviation between the predictions and the actual conditions. It is proposed according to the invention to store the frequency and range of known transmitters at the location of the direction-finding receiver and confirm the direction of these known transmitters at regular time intervals during a measurement phase. Actual measurements of the relationship between the vertical frequency and the virtual height of the ionospheric layers can be obtained from the elevation angles measured in this case and the stored transmitter data. The predicted ionogram is matched to the actual measurements by varying the parameters, layer heights and limiting frequencies, and the ionogram corrected in this way is used as the basis for subsequent determinations of the locations of unknown transmitters.

Title: Process for controlling underfloor heating
Inventor: STUMPFROCK KURT
IPC: G05D23/19
Filed: 1987-03-16
Abstract: In known underfloor heating systems, the heating circuits are preadjusted corresponding to the calculated heat power by throttling. Because of the throttling, the heater pipes no longer give off heat over their entire length. This results in cold and warm zones on the floor surface. The novel process will make it possible to achieve preadjustment of the calculated heat power and adaptation to the requirements of the operator with a uniform floor surface temperature. The heater circuits of a room are preadjusted by periodic switching on and off of the volume current of water, and are matched to the requirements of the operator by a manual switch or a room control. Control of a floor heater with liquid heat carrier medium.
