Patent DE-4128365-A1 (DE)
Inventor: EVERTZ EGON
IPC: B22D11/04
Filed: 1991-08-27
Abstract: The invention relates to the repair of one-piece copper moulds 6 for the continuous casting of steel which have become unusable due to wear. The removal of the inner sides to the depth of the wear is known. However, as a result the mould (6) becomes thinner than before until, finally, it can no longer be used for thermal reasons and for reasons of strength. The invention restores all the original dimensions of the mould 6 by a process in which, first of all, the outer sides of the mould are coated with copper, a mandrel defining the inside dimension 2 of the mould 6 is inserted into the mould 6 and the latter is then drawn through a die so that its inner side rests against the mandrel and its length increases 5, the inside dimension 2 and the outside dimension 1 corresponding to the original dimensions. The mould is then shortened in length, thus reestablishing the length dimension as well. <IMAGE>

Patent DE-4226047-A1 (DE)
Inventor: PARK YONG-BO
IPC: G11C5/14
Filed: 1992-08-06
Abstract: A circuit for generating an internal voltage to be supplied to memory elements of a semiconductor memory chip during normal operation and for providing an external voltage to the memory elements during a burn-in test operation. The circuit may be constructed with a driver circuit (50) which receives an external voltage and is controlled to generate the internal voltage. A comparator (300) compares the internal voltage to a first reference voltage to produce a control signal G2 to control the driver circuit (50). An external voltage detector (100) compares a second reference voltage to the external voltage to generate control signal B2. A driver control circuit (200) is enabled by control signal B2, if the external voltage is less than the second reference voltage, to pass control signal G2 to the driver circuit and thereby enable generation of the internal voltage to be equal to, or less than, the operating voltage of the semiconductor memory chip. The driver control circuit is disabled by control signal B2 if the external voltage is greater than the second reference voltage, thereby preventing the control signal G2 of the comparator from controlling conduction by the driver circuit (50) to enable output of the external voltage exhibiting an elevated amplitude to the memory elements for burn-in test operation.

Title: Digital audio signal transmitter serving several programme- presenting stations - each allocated to DSR receiver, using received DSR clock pulse signal for synchronisation of digital audio signals
Inventor: KIRCHNER JOSEF DIPL ING
IPC: H04H20/51
Filed: 1992-11-05
Abstract: The DSR transmission system uses a satellite transmission path reducing the transmitted digital audio signals by MUSICAM coders, compatible with the human ear. They are transmitted to a ground station via a single channel per carrier channel of the satellite transmission path, and retransmitted as a DSR signal pack to the individual transmitters of the radio transmission network. Each programme-presenting station is allocated a DSR receiver, which uses the received clock pulse signal for synchronising the data reduced, digital audio signals to be transmitted. In the ground station, the so synchronised transmitted, data reduced, digital audio signals of the single channel per carrier channels are directly fed to a DSR modulator and transmitted as a DSR signal packet to the network transmitters. ADVANTAGE - MUSICAM coded signals transmission with small number of appts. without quality loss.
