Patent EP-0094671-A2 (EP)
Inventor: ODAKA KENTARO
IPC: G06F11/10
Filed: 1983-05-16
Abstract: In the recording/reproducing of digital audio signals, errors are detected and corrected by using two parity words, one arranged at the center of the block formed of data words and the arranged at one end of the block. The probability that uncorrectable error will be present in the center of the block is relatively high, so placing the parity word there prevents loss of the more valuable data. Maximum correctable burst errors are determined by the length of the block, so placing the other parity word on the end of the block lengthens it and improves burst error correction. The parity words are arranged as indicated before adding a cyclic redundancy check (CRC) code to the data signal and then modulation coding the signal before recording. During playback, the reproduced signal is demodulated and the CRC code used to detect errors for which error pointers are generated. The reproduced data is read into memories (3,4) in accordance with generated addresses and the pointers prevent the writing in of words found to be in error, which error words are subsequently corrected if possible using parity codes originally encoded into the signals prior to recording.

Abstract: Transmitting/receiving device with a diode and an optical fiber optically coupled to an optical window of the diode, where the diode is positioned on a support with a lead-in for inserting the optical fiber. For such a transmitting/receiving device the optical fiber of the diode can be easily and accurately adjusted and subsequently permanently positioned. The invention makes provisions for a cone-shaped lead-in with the diode located at the larger opening of the lead-in. This results in an especially easy adjustment of the optical fiber with respect to the diode. The device can be used in opto-electronic receivers having a so-called "pigtail" connection.

Title: Force transmitting junction for wooden elements
Inventor: BERTSCHE PETER
IPC: E04B1/49
Filed: 1984-05-18
Abstract: To produce a junction for wooden elements, in particular one which can be put under tension, a bore for receiving a dowel is made in the surface of the wood adjacent to the joint. This dowel possesses force-transmitting members which are retracted on introduction of the dowel into the associated bore and are then extensible in such a way that they extend transversely to the dowel and penetrate into the wood surrounding the dowel to such a depth that they can transmit force between dowel and wood. The size of the force to be transmitted depends upon the smallest occurring cross-section of the dowel body and the number and form of the force-transmitting members. Instead of a dowel body, elongated strips separated from one another and reinforced by pins can also be used, the said strips being introduced into the bore and then pressed radially outwards by means of a tool. <IMAGE>

Title: A.C. supply converter
Inventor: MAYTUM MICHAEL JOHN
IPC: H02M5/14
Filed: 1984-04-05
Abstract: A direct a.c. supply converter for converting an N (2) phase input voltage system into an a.c. output voltage system of different frequency, amplitude, and/or phase using width-modulated contributions from the phases of the input voltage system to produce the output voltage system suffers from the disadvantage that the maximum output voltage amplitude can be limited to the minimum instantaneous voltage of the input voltage system because of the arbitrary timing relationship between the two voltage systems. This limitation is relieved by the addition of a component at the N th  harmonic of the input system frequency to the width-modulation so that the effective minimum instantaneous voltage of the input system is increased. An increase in the maximum outputvoltage amplitude can also be obtained by adding to the width-modulation a component at the P th  harmonic of the output system frequency; this can be used alone or in conjunction with the component at the N th  harmonic of the input system frequency.

Abstract: @ A coin testing apparatus subjects a coin inserted into a coin entry (1) and rolling down an inclined track (2) to testing at a testing station (3) comprising sensors (4,5,6) which may for example be inductive sensors. If a coin is found to be acceptable an accept signal is generated and this causes gate mechanism (8) to open to permit the coin to access accept path (9), the gate mechanism (8) being normally closed so that unacceptable coins can only access a reject path (10). A post-gate detector (11) in the accept path (9) senses the passage of an accepted coin and serves to close the gate mechanism (8) and also to determine allocation of a customer credit. A pre-gate detector (12) upstream of the gate mechanism (8) has its output logically processed with the accept signal produced when an acceptable coin is tested and/or with the output of the post-gate detector (11).

Abstract: Vehicles are measured and photographed from the direction in which they are travelling by a Doppler radar speed measuring device equipped with a camera. During a measuring stage after the vehicle enters the radar beam, a measured speed value is determined and when this exceeds a specific limit value, the camera is triggered. The Doppler signal for checking the measured speed value is then further evaluated over a verification distance. If the measured speed value is confirmed then it is printed on the photograph at the end of the verification distance, if it has not been confirmed, then a cancellation indicator is printed. The film is then advanced and the detection of the entry of another vehicle is awaited. As a result of this checking of the measured speed value, the measuring reliability when registering oncoming vehicles is substantially increased and overtaking in particular can be detected in the range of the radar beam.
