Title: Arrangement for tuning a single sideband receiver
Inventor: FRITZE BERND DIPL-ING
IPC: H03J7/02
Filed: 1982-03-19
Granted: 1983-11-24
Abstract: For fast and accurate tuning of a single sideband receiver to a speech-modulated transmission, the respective speech frequency spectrum is determined repeatedly in succession by means of a fast Fourier transformation from the time function of the demodulated sideband signal, this spectrum is then checked for the presence of a plurality of amplitude maxima with the same frequency interval within a narrow tolerance range and frequency grids underlying these spectra are then determined therefrom, whereupon the frequency value which is common to most of these frequency grids is identified and the receiver tuning is then modified by this frequency value identified in this way. <IMAGE>

Title: Initiating device for speed regulation
Inventor: HEINTZ THEO
IPC: F01D21/02
Filed: 1982-11-16
Granted: 1984-06-07
Abstract: The invention relates to a device for speed regulation of a machine to which a flowing medium is applied, especially a steam turbine, having a speed regulator which is preferably of mechanical-hydraulic construction, having a hydraulic actuating motor, and having an actuating valve for the flowing medium. The ever-increasing power density of such machines results in particular difficulties in speed regulation since, on the one hand, there must be sufficient stability in all operating modes and, on the other hand, the speed regulation is required to react powerfully and quickly for the initiation of loading and, especially, unloading processes. In order largely to avoid the compromises which were necessary in the past for optimisation, it is proposed that the speed regulator, which is known per se, is matched to normal speed changes throughout the adjustment range, while a higher-lever regulating device is provided for larger and, in particular, faster speed changes outside the said limits in the region of the rated speed. This regulating device has an actual value signal from a speed sensor applied to it and it generates an output signal for rapid operation of the actuating valve for the larger cases of unloading, or loading as well, and accelerations or decelerations. <IMAGE>

Title: Monitoring aircraft projectile or missile - using two extrapolation units to predict flight path
Inventor: SCHUMACHER WOLFGANG DIPL-ING D
IPC: G01S13/72
Filed: 1984-01-13
Granted: 1991-05-02
Abstract: A measuring unit (114) establishes the instantaneous location and movement parameters of a flying object.  A first extrapolation unit (118) predicts future values of the parameters, if necessary under the assumption that one of the parameters stays constant. A second extrapolation unit (120,122,124,126,130) considers an extrapolation error as a difference between the parameters calculated for a certain time and the parameters received from the object itself for this time, minimising the error so that it matches an error model in a continuous run of values. USE/ADVANTAGE - Improved accuracy of prediction.  Suitable for military use.

Title: Method and device for testing the structural stability of chipboard
Inventor: ROSENKE UDO DIPL-ING
IPC: G01N3/00
Filed: 1984-01-28
Granted: 1985-08-14
Abstract: In this method, a flat test body (2) is driven into the central plane of the narrow face of the chipboard (1) and is then twisted with a predefined torque. The angle of twist of the test body (2) in the chipboard (1) resulting therefrom is a reliable measure of the structural stability of the chipboard, which in its turn is essentially determined by the gluing strength between the chips. The device for implementing the method comprises a blade-like test body (2) of flat material, which is attached to the end of a rotatably mounted shaft (3). The shaft (3) can be moved, by means of a cylinder (5) actuatable by a pressure medium, so as to drive in the test body (2). For the purpose of twisting the shaft (3), the latter carries a rotor disk (6) which is arranged within the stator (7) of an electric twisting drive. <IMAGE>

Title: All-wheel drive motor vehicle
Inventor: BARSKE HEIKO DR
IPC: B60K17/348
Filed: 1985-05-10
Granted: 1986-06-26
Abstract: In a motor vehicle with a front and a rear axle, each drivable by way of a differential, and a transmission driving the differentials, which transmission produces a possibly different drive torque distribution to the axles, in order to obtain an optimum cornering control as a function of the steering angle of the front wheels, the drive torque distribution can be reduced to 15% or on the rear wheels increased to 85%. The drive torque is varied smoothly as the steering angle increases and where necessary with increasing drive power output of the internal combustion engine.

Title: Method of converting the picture frequency of television signals of a first television standard to the picture frequency of television signals of a second television standard
Inventor: EBNER ANDREAS DIPL-ING
IPC: H04N7/01
Filed: 1985-09-04
Granted: 1987-01-08
Abstract: To convert the picture frequency of television signals of a first television standard to the picture frequency of television signals of a second television standard, it is proposed that the picture frequency of the television signals of the first television standard should be doubled before conversion. This is done by interpolating an intermediate picture from in each case two successive half-pictures. The doubled picture frequency is then converted to the picture frequency of the television signals of the second television standard partly by omitting intermediate or half-pictures, and partly by interpolation of intermediate pictures and neighbouring half-pictures, in a sequence which corresponds to the ratio of the doubled picture frequency and the picture frequency to be generated.

Abstract: In the annealing of steel strip of low carbon content under a carbon-containing blanketing gas, black annealing edges occasionally appear due to residues from cooling lubricants during rolling. To avoid these black annealing edges, the carbon-containing blanketing gas is replaced during the annealing by a carbon-free blanketing gas such as nitrogen or hydrogen.

Abstract: In a known teleconferencing system, a noise-adapting threshold circuit is used to generate a voltage level which is representative of the background noise and is compared with the microphone signal of a relevant microphone in order to ascertain whether the microphone is receiving speech. The invention is designed to enable clear identification of speech signals. To achieve this, after micro-individual bandpass filtering in the fundamental voice frequency range, the speech envelope is detected from the composite microphone signal adjusted according to the ambient noise, the level of the bandpass-filtered microphone signals is monitored and the microphone signal with the highest level, depending on the speech envelope detection signal, is passed onto the transmission path. The method according to the invention is particularly suitable for use in hands-free conferencing devices in noise-filled rooms, where the remote station is connected to the hands-free conferencing device via a telephone circuit. <IMAGE>

IPC: C06D3/00
Filed: 1993-10-29
Granted: 1995-03-02
Abstract: In a continuously burning pyrotechnic charge, compounds of graphite serve as additional charge components which are capable of thermal expansion in the c-axis perpendicular to the lattice plane and expand in the reaction zone of the pyrotechnic charge and are liberated with the reaction products of the burning pyrotechnic charge.

The balloon surface penetrates the annular space where the thread guide runs. Also claimed are an appts. for implementation and an alternative form of combined spin-twister.  Pref. removal of fibre from the annular space occurs at a spot opposite the feed point or at a spot displaced in the balloon rotation direction. The fibre feed entry is displaced w.r.t. the feed exit in rotation direction. There are pref. three ring connecting spokes, of circumference greater than half the longest fibre and the annular space is subjected to low pressure and sealed against inner, outer housings.
