Title: Mobile concrete mixer having automatic control
Inventor: PHILIPP RAINER DIPL ING
IPC: B28C5/42
Filed: 1988-07-19
Abstract: During the filling of the mobile concrete mixer drum, the motor speed must be set to the maximum value. If the filling takes place batch-wise via 1 m<3> compulsory type mixers, for example, then the vehicle drive or separate drive runs for approximately 5-10 minutes at the hitherto manually set maximum speed. According to the invention, the noise generation, the wear and the energy requirement during filling are reduced in that, immediately after a charge has run in, the idling speed of the drive motor and, synchronously with the latter, a low drum speed is automatically set. The setting of the in each case lower speed is executed, in this arrangement, at the mixing plant 1 or by the operator 18 at a removal conveyor belt 17, via wireless control. Conversely, the rotational speed is automatically raised, under control (for filling). <IMAGE>

Patent DE-3837487-A1 (DE)
Inventor: HENSEL BERND
IPC: C23G5/00
Filed: 1988-11-04
Abstract: An etching method whereby a sufficiently high etching rate is attained, in a uniform surface treatment that is very gentle on projecting edges of the substrates. Also the substrates are held at or brought to a sufficiently high temperature by the etching process. The method for etching substrates with a magnetic-field supported low-pressure discharge is characterized in that the magnetic field is decoupled from the substrates such that the magnetic field strength at the substrates is less than 6000 A/m. In the space between the substrates and the magnet system at least one electron emitter is disposed at a location at which a magnetic field strength is present that is greater than the field strength at the substrates but equal to or less than 12,000 A/m. On the side of the substrates facing away from the at least one electron emitter, at least one anode is disposed with an anode potential of +10 to +250 V with respect to ground. An etching potential between -100 V and -1000 V with respect to ground is applied to the substrates. The ratio of the gaps between the substrates and the surfaces of the substrates projected onto a projection plane carried through the gaps amounts to at least 0.1. The potential difference between the at least one emitter and the at least one anode is selected so high that an electron current (primary and secondary electrons) flows through the substrate gaps to the anode.

Patent DE-3907098-A1 (DE)
Inventor: HEGENDOERFER MAX DIPL ING
IPC: H04N5/782
Filed: 1989-03-07
Abstract: To simplify the preprogramming of receivers, particularly of video recorders, taking into consideration timeshifts in the programme contribution concerned, it is known to generate additional information items such as programme source information, day of the week, start time and end time at the transmitting end, which are transmitted together with the television signal. These additional information items are also contained in the programme tables of a teletext signal and can be input into a memory of the receiver on command. When the transmission is shifted, for example by one "VPS day" or more, a further additional information item is generated at the transmitting end, by means of which updating, in particular correction, of additional information items already stored in the receiver is made possible. The novel method can also be used for controlling receivers which only contain a VPS decoder for decoding the additional information items. <IMAGE>
