Patent DE-2938750-A1 (DE)
Inventor: HAGEN ROLF DIPL ING
IPC: H04L25/38
Filed: 1979-09-25
Abstract: A circuit arrangement is provided for the transmission of digital signals between transmitting and/or receiving stations which operate with differing data transmission procedures and with different data formats. The signal transmission respectively occurs by way of a converter unit which, like the transmitting and receiving installations, is connected to a switching system. In the train of the transmission of digital signals from a transmitting installation operating with a lower data transmission rate to a receiving installation operating with a higher data transmission rate, the digital signals emitted by the appertaining transmitting installation are first collected in the converter unit in order to be emitted to the appertaining receiving installation only given the existence of a sufficient plurality of such signals. The transmission of digital signals from a transmitting installation operating with a higher data transmission rate to a receiving installation operating with a lower transmission rate occurs in data blocks. A respective plurality of data signals forming a block or, respectively, a signal group, is emitted together with a signal group end mark by the appertaining transmitting installation to the converter unit which then relays the digital signals to the appertaining receiving installation. In order to minimize control expense, the converter unit checks its signal acceptance capability upon the occurrence of the group end mark. Only given existence of a sufficient signal acceptance capability in the converter unit is an acknowledgment character emitted to the transmitting installation, the acknowledgment character then causing the transmission of signals forming a further signal group or block. The invention is preferably employed for signal transmission between telex stations and office printergram or teletex stations.

Title: Closed cycle power producing process - has working gas in tubular circuit set in motion by single impulse to continue flowing
IPC: F24S90/00
Filed: 1980-05-16
Abstract: Gas is contained in four tubes connected to form a closed rectangular circuit in a vertical plane. There is a heat exchanger (W3) at the top of one vertical leg and another (W1) at the bottom of the other leg. When the heat exchangers are out of use the gas in the two vertical legs (K1,K2) is at the same conditions with increasing potential downwards. A single impulse sets the gas in motion round the circuit. As it flows it undergoes an adiabatic expansion (K2) followed by an adiabatic compression (K1). A turbine (T) in the top horizontal branch can extract useful work from the gas.
Patent DE-3019863-A1 (DE)
Title: Solar collector heat exchange plate - has pipes expanded against plate by internal medium pressure to remove gaps between parts
Inventor: HANDL AUGUST
IPC: F24S10/75
Filed: 1980-05-23
Abstract: The heat-exchanger plate is for a solar collector or for heating, having a metal baseplate to which pipes for a heat-exchange medium are fixed by strips. Each pipe (3) is of material expanding under the internal pressure from the medium, so as to bear when in use against the strip (2) and plate (1). This can cause the plate to distort where the pipe bears against it, and the pipe can assume a flat oval cross-section. This avoids the need for filling intervening spaces between the pipes and plate with heat-conductive material.
Patent DE-3030298-A1 (DE)
Title: Liq. dopant for coating substrates with doped oxide layer - esp. where semiconductor wafers are coated with mixt. of ethyl orthosilicate, solvent and boric acid
Inventor: KUISL MAX DR RER NAT
IPC: C30B31/02
Filed: 1980-08-09
Abstract: Liq. dopant is made by mixing an ester of orthosilicic acid, a solvent, and an aq. acid phase contg. a dopant. Before the liq. is used on a substrate, it is treated with a drying agent to remove water, so the volatility of the dopant out of the oxide layer is decreased. The pref. mixt. uses ethyl orthosilicate as the ester, whereas the dopant is either boric acid or arsenic acid. The drying agent is pref. a molecular sieve. Such mixts. are used in the "spin-on-technique" to form a doped oxide layer, but when the layer is stored in damp air the dopant volatilises. The invention avoids this problem. The mixt. used in the invention employs inexpensive dopants, esp. boric acid, and provides an oxide layer which does not readily lose boron.
Patent DE-3031438-A1 (DE)
Title: Equalising circuit for multiple channel analogue system - has timing circuits for each signal to avoid sudden output changes due to input signal failure
Inventor: MACHAC VLADIMIR DIPL ING
IPC: G05B9/03
Filed: 1980-08-20
Abstract: This equalising circuit is for a multi-channel analogue system, such as may be used e.g. for a pressure regulation in boiling water reactors, and solves the problem of sudden changes of output signal due to the absence of one of the input signals by the use of special timing circuits for each input signal. It will, however, still follow rapid changes of input signals. The output (A1) of an averaging circuit (1) together with one of the input signals (E1,2,3) is fed to timing circuits (9,10,11) whose output at first follow their respective input signals, but are subsequently reduced to a common value and averaged by a select circuit (22) whose output (A2) is linked with the output (A1) of the first circuit.
