Patent DE-3744691-A1 (DE)
Title: Assessing method for received radar pulses
Inventor: GAILER JAMES MARTIN
IPC: G01S7/02
Filed: 1987-08-19
Abstract: The assessment method involves comparing a value of each characteristic for a currently received pulse with a mean value for previously received pulses to provide a currently measured increment. The latter is subjected to a probability process to provide a confidence value for the associated pulse and characteristic. The confidence values for the set of characteristics w.r.t. the associated pulses are combined to provide an overall confidence value for the associated pulse. The pulse characteristics include at least two of: the target angle; the pulse power level; the pulse width; and the pulse repetition interval. The target angle and associated probability process can take account of an estimated thermal noise component of the currently received pulse in determining an angle confidence value.
Patent DE-3802579-A1 (DE)
Inventor: BRUENLE SIEGFRIED DIPL ING
IPC: H04Q3/68
Filed: 1988-01-29
Abstract: A three-stage non-blocking switching array having twice the number of inputs and outputs for its sub-arrays of its input and output stages as the number of lines to be switched, and having one more sub-array in its intermediate stage than the minumum required to form a non-blocking switching array. The additional or redundant inputs and outputs are connected with the non-redundant inputs and outputs such that the redundant inputs are each individually connected with a non-redundant input of a respective other sub-array of the same respective stage. This construction maintains the non-blocking characteristic of the switching array even if one of the sub-arrays fails since, in such use, redundant substitute paths are available.

Patent DE-3806550-A1 (DE)
Title: Dialling device
Inventor: ARCISZEWSKI KASIMIR
IPC: H04M1/724
Filed: 1988-03-01
Abstract: A dialling device contains a first memory part (2), data which correspond to complete dial signals and, in a second memory part (4), speech signals. The data of the first memory part (2) are output with a first retrieval and addressing device (6) to a dial signal generating circuit (8) by means of which corresponding dial signals are output to a dial signal line (10). The speech signals of the second memory part (4) are accessed by means of a second retrieval and addressing device (12), the speech signals associated with each data element of the first memory part (2) being output with a listening device (18). By means of a controller (14), an operator can invoke the "actuate" function with an actuation device (16), whereby the selected dial signal is output by the dial signal generating circuit (8). However, if the "move to next" function is invoked, the next speech signal stored in the second memory part (4) is output with the listening device (18). With a list of telephone numbers pre-entered in a list memory (28), the actuation device (16) can be controlled in such a way that speech signals and/or keyword speech signals characterising the subscriber are in each case output only when one of the required dial-up connections has been set up. <IMAGE>

Patent DE-3809189-A1 (DE)
Title: Method and device for the measurement of flow velocity using ultrasonic waves
Inventor: CHUBACHI NORIYOSHI
IPC: G01F1/66
Filed: 1988-03-18
Abstract: The invention proposes a method and device for the measurement of the flow velocity of a fluid flowing through a pipe. A pair of ultrasonic transducers which are arranged at two places on a pipe section emit alternating ultrasonic waves in order to obtain the phase velocity and the group velocity. A measurement is made of the difference between time durations which the ultrasonic waves need to be propagated through the fluid until they are received, by which means the sound velocity is obtained. The flow velocity is determined from the sound velocity, the phase velocity, the group velocity and the measured time difference by means of a predeterminable calculation. In addition to the ultrasonic convertors, the device is provided with a signal-processing unit for the calculation of the phase velocity, the group velocity, etc., and with a circuit for obtaining the difference between wave-receiving time durations. <IMAGE>

Title: Device for safely installing and removing the front springs (shock absorbers) of motor vehicles
Inventor: MEINHARD WOLFGANG
IPC: B25B27/30
Filed: 1988-03-25
Abstract: Device for safely, easily and quickly removing and installing front springs in motor vehicles. The device is characterised in that it ensures particularly safe handling and can be used universally: this is particularly favourable with respect to costs. It is also favourable that the lifting device (pressure component) can be replaced by a customary vehicle body press. By means of the horizontal insertion of the cable in an intermediate space of the spring and subsequent rotation of the same, the cable is moved in the Y direction until the loop fits over both rollers. By fastening the device to the spring, slipping is prevented. By means of a pressure device (cylinder) the cable is tensioned in such a way that the spring is compressed. The length of the spring is reduced and the spring can be removed easily. By maintaining pressure the spring can also be inserted again if a new one is not to be inserted.

Title: Method for controlling a hydrogen electrolysis arrangement
Inventor: KREUTER WALTER DIPL ING DR
IPC: C25B15/02
Filed: 1988-09-30
Abstract: A hydrogen electrolysis arrangement is controlled, using the through-flow quantity of the product gases, after separating off entrained electrolyte. By means of detectors for the through-flow quantity, which detectors are connected via signal lines to the rectifier unit of the system, the current for the electrolysis can be continuously regulated between 0 and 100%. In the case of high gas consumption, i.e. high through-flow quantity, the current intensity is increased, while the current intensity is reduced in the case of falling demand. This control can advantageously be used in pressure electrolysis systems, since through controlling the production power of the electrolysis via the consumption, intermediate storage of the product gases can be obviated.
