Title: Cooling water regulator for internal combustion engines
Inventor: WAHLER DIETER DIPL ING
IPC: G05D23/13
Filed: 1983-04-27
Abstract: A cooling water regulator for internal combustion engines is proposed with a thermostat valve with expansion material thermostat for the actuation of the valve element controlling the valve seat. The plunger of the expansion material thermostat is supported by means of an abutment, whilst the housing with valve disc can be displaced against a return spring in the event of expansion of the expansion material. The abutment is formed from a movable, adjustable control element which can be actuated by means of a control device operating as a function of an external variable of a medium, especially the temperature. As a result it is possible to automatically vary the operating point of the thermostat valve as a function, for example, of the temperature of the oil or exhaust gas of the internal combustion engine or the ambient air, so as to advance or delay opening of the valve, with automatic adjustment to temperature changes.

Title: Seal for a pitched-roof window
Inventor: SIEBEL HELMUT
IPC: E04D13/03
Filed: 1983-10-18
Abstract: The invention relates to a seal for pitched-roof windows, which is located on the bottom edge of the window pane between the window pane and the window frame. The window pane lies on this seal in a narrow region. This narrow bearing region is according to the invention kept free from moisture and any moisture which nevertheless penetrates is quickly caused to flow off or evaporate by good ventilation. The good ventilation is achieved in that the pane rests on somewhat projecting parts, such as e.g. knobs, between which there are recesses which are connected to the external air. Additionally, any condensation water forming and running down on the inside of the window pane is diverted, by a sealing lip pointing upwards on the seal, downwards to the inside of the window frame, from where the water is collected in a collecting plate covering the front side of the window case and conducted to the outside between the closing joint between window frame and collecting plate. <IMAGE>

Title: Monitoring system for heating devices
Inventor: STANZEL ERWIN
IPC: H02H5/04
Filed: 1983-11-08
Abstract: The invention relates to monitoring systems for the serviceability of heating systems, especially for electrical, self-regulating heating strips. According to the invention, the problem is solved by measuring electrical inductance or capacitance at the end of the heating circuit, with a connection to an alarm device, or by the connection of an ammeter with an electronic circuit for determining current changes, having a connection to an alarm device. A further solution is represented by the connection of a transmitter to the end of a heating circuit, which transmitter superimposes a high frequency on the heating current, the interruption of which high frequency in the event of a failure of the heating current is recorded in the supply part in the receiver. The problem is furthermore solved by guiding an optical fibre having temperature-dependent transmission properties along the heated object, said optical fibre being coupled to an alarm device.

Title: Optoelectronic component, in particular a laser diode or a light-emitting diode
Inventor: ENNEN HELMUT DIPL PHYS
IPC: H01S5/30
Filed: 1983-12-07
Abstract: A laser diode or a light-emitting diode has a semiconductor crystal doped with lanthanides (4f ions). As a result of doping InP, GaAs, GaP, Si and Ge with lanthanides, a light-emitting diode is able to produce incoherent radiation and a laser diode coherent radiation whose wavelength is longer than the band gap of the host crystal and is primarily determined by the 4f ion (lanthanide) and not by the band gap of the semiconductor. Doping with erbium results in a semiconductor component emission wavelength of 1.54  mu m, which approximately corresponds to the wavelength for minimum attenuation in a glass fibre such as is used for glass-fibre communication.

Patent DE-3418085-A1 (DE)
Title: Iron production process
Inventor: BOGDANDY LUDWIG VON PROF DR IN
IPC: C21B13/14
Filed: 1984-05-16
Abstract: The process relates to the production of iron from an iron-oxygen compound, preferably ore, which, in an ore reduction vessel, is reduced, using essentially the reaction gases from the smelting vessel, to a metallisation degree of approximately 50%. In a separate smelting vessel, said prereduced ore is smelted with the addition of carbon-containing fuels and oxygen-containing gases, for example oxygen or air. The reaction gases escaping from the liquid iron undergo afterburning to from 30 to 40% in the smelting vessel, and the heat produced in the process is largely transferred to the melt. The reaction gases are further cooled on their way from the smelting unit to the ore reduction vessel by reduction with reductants.
Patent DE-3419288-A1 (DE)
Inventor: REINIGER JUERGEN
IPC: G06K15/12
Filed: 1984-05-23
Abstract: The invention relates to an improvement in a method for the synchronization of a material web, particularly a photosensitive material web in a photo typesetting process. Typically, an optical path is transverse to the direction of motion of a material web normally transportable with an approximately constant transport speed. The web is deflected into deflection lines, and if necessary scanned, to have images exposed. The transport speed and the deflection speed are controllable by common clock pulses. At the beginning of each deflection line, a reference signal (SOL) for time and deflection position is generated. In order to retain, in case of an interruption of the scanning, the regular scanning structure of the scanning on the material web, the following steps are provided as an improvement. In case of an interruption of the scanning, reference signals are generated while line-wise deflection of the optical path is continued. The material web beginning with a first selected reference signal after the interruption is slowed down by n clock pulses to standstill. Beginning with a subsequent reference signal, the material web is accelerated by n clock pulses to an identical return speed opposed to the transport speed. Subsequently it is reset by p clock pulses with the return speed up to a subsequent reference signal. Starting from the last-mentioned reference signal, the material web is slowed down by n clock pulses to standstill. After a variable interval up to a reference signal, the material web is accelerated by n clock pulses to the transport speed and subsequently, by p clock pulses up to a following reference signal, is passed with the transport speed into a scanning position which is equal to the scanning position with the first selected reference signal.
