Patent DE-3831994-A1 (DE)
Title: Antenna system
Inventor: OTTO BERNHARD
IPC: H04N7/173
Filed: 1988-09-21
Abstract: When a satellite antenna is subsequently installed, the installation of the expensive coaxial cable is associated with problems. This is why the satellite receiving unit is arranged under the roof in the vicinity of the parabolic antenna. Although the modules required for this can be calibrated, they cannot be remotely controlled. This is why the satellite unit arranged under the roof is made to be remotely controllable in that, for example, signals switch the various modules via the antenna cable. This can be done, for example, via the infrared remote control. The control signals can also be transmitted via the mains line. Remote control with the aid of an RF transmitter is also possible.

Patent DE-3907351-A1 (DE)
Title: Mould with pouring-in funnel
Inventor: GROTHE HORST
IPC: B22D11/04
Filed: 1989-03-08
Abstract: It is known that the change in shape, required in each case, of the strand shell of a cast strand in the pouring-in funnel of a mould is not evenly distributed from the start of solidification until the cast metal strand leaves the mould, especially a short distance below the surface of the metal bath. This leads not only to the formation of cavities into which liquid slag can penetrate, leading to unevenly intense cooling of the strand shell and resulting in depressions and cracks, but also causes signs of separation of the strand shell from the mould wall. According to the invention, however, these disadvantages are avoided in that the contour (9) of the inner wall of the pouring-in funnel (2) is constructed in the strand flow direction such that its radii (R1, R2), becoming gradually larger in the strand flow direction, merge into the contour (9') of the inner wall of the mould (1). As a result of this construction of the pouring-in funnel according to the invention, the manufacture of metal strands with homogeneous, defect-free surface condition of high quality is made possible. <IMAGE>

Title: Device for milling the sheet edges of a clamped sheet stack
Inventor: TSCHIERS BERNHARD
IPC: B26D7/02
Filed: 1989-06-16
Abstract: The invention relates to a milling device for machining the sheet edges (2) of sheet stacks (1). The sheet stack (1) clamped between clamping jaws (7, 8) is moved passed the rotating milling head (10) and has to be supported against the cutting pressure. The friction occurring thereby and the cutting force of the milling head (10) have to be overcome by the drive force for the advance of the sheet stack (1). However, safety regulations demand the automatic cut-out of the advance when a relatively low resistance is reached. In order to satisfy these conditions, the sheet stack (1) is supported relative to the milling head (10) by supporting discs (14) mounted on ball bearings, and there is provided, in the advance drive for the clamping station (3), a safety slipping coupling (37), the slip moment of which is lower than a frictional resistance which would occur if the sheet stack (1) were supported on fixed guides. This makes it possible to comply with the safety regulations. <IMAGE>

Patent DE-3927620-A1 (DE)
Inventor: DOBBERSTEIN JOACHIM DIPL ING
IPC: H02J13/00
Filed: 1989-08-22
Abstract: In ripple-control transmitting installations, which consist of a ripple-control centre and a plurality of decentralised substations, each substation containing a ripple-control transmitter which supplies a ripple-control message into a current supply network, it is intended that the ripple-control message be supplied synchronously by the individual transmitters. The invention proposes a method for transmitting a data message from the ripple-control centre to the substations and for synchronised generation of a ripple-control message in the substations which corresponds to the data message. In this method, the data message is transmitted in the multi-point traffic from the ripple-control centre to the substations, acknowledgement of receipt of the data message is asked for and, if necessary, the data message is transmitted repeatedly. In the substations, receipt of a data message initiates the start of a delay period after which the ripple-control message is transmitted provided no countermand message, transmitted by the ripple-control centre, occurs before the delay period has elapsed. <IMAGE>
