The process is carried out in such a manner that the cooling medium is atomised into microdroplets and the mist thus formed is led over the surface of the extrudate. A cooling device for carrying out the process consists in providing a structural unit which is formed from a water tank, a blower and an oscillator and can be connected to a feed line for supplying the water mist to the extrudate.
Patent DE-3416932-A1 (DE)
Title: Catalyst installation
Inventor: NAEGELER GERD
IPC: F01N3/24
Filed: 1984-04-30
Abstract: The combustion gases flow from the engine block (1) through a bend (5) and a manifold (6) through a filter sieve (7). They then flow into a reduction apparatus (8) for cleavage of the nitrogen oxides NxOy into N2 + O2. In the subsequent oxidation apparatus (9) having a continuous ignition device (13, 17, 18), CO and CnH(2n+2) are subjected to afterburning to form CO2 and H2O. The conventional silencer (10) is arranged subsequently to the reduction chamber, at the end of which silencer the exhaust gas return (16) is connected to a fan (12). The fan sucks in fresh air via a suction channel (14) and conducts this together with the incompletely combusted exhaust gases via the channel (15) back to the oxidation chamber (9). The entire installation is closed to the exterior by a cleaning filter (11) which retains suspended matter. The continuous ignition device has the task of aiding the afterburning. This installation was created for motor vehicles which can be powered even by lead-containing petrol. <IMAGE>

Patent DE-3433943-A1 (DE)
Title: Sight for sporting weapons
Inventor: GEHMANN MARKUS
IPC: F41G1/04
Filed: 1984-09-15
Abstract: When aiming using an aperture front sight, the white surface (which surrounds the firing disc mirror) frequently leads to dazzling of the person firing and hence to aiming errors. In addition, as a result of the bars which are generally provided in such a sight, lead away from the aperture front sight (which is in the form of a circular ring) and make it possible to monitor the horizontal position of the weapon, a part of the target field is covered. In order to overcome these disadvantages, it is proposed to fit a disc consisting of optically polarising material around the aperture front sight, from which disc bars which lead away can be fitted, possibly likewise consisting of optically polarising material, this disc preventing the dazzling by the light reflecting the white surface. <IMAGE>

Title: Telecommunications system with a plurality of subscriber stations accessing a common transmission medium
Inventor: ZELLER CHRISTOPH
IPC: H04L12/433
Filed: 1984-11-15
Abstract: In a local area network with a plurality of subscriber stations accessing two optical waveguides which are operated in opposite directions, are separated at one point and form a loop bus, the access authorisation is forwarded in decentralised polling from station to station by through-connection of station-individual address counters, the access authorisation, if there is no response from one station within a predefined time period, being passed on to the next station and a subscriber station transmitting a useful telegram which is to be output only if access authorisation is granted when its address is displayed by its address counter; the address of the sender contained in each useful telegram transmitted is compared in each subscriber station with the address which has just been output by the station-individual address counter, the counter reading being corrected accordingly if said addresses do not match.

Patent DE-3447988-A1 (DE)
Title: Method for transmitting a colour television signal in time-division and frequency-division multiplex
Inventor: HOLOCH GERHARD DIPL ING
IPC: H04N11/06
Filed: 1984-09-27
Abstract: To transmit a colour television signal which contains a luminence signal component and a modulated colour subcarrier, only the luminence signal is transmitted with the full band width of the transmission channel during an arbitrary line and during the subsequent line a frequency division multiplex is transmitted which consists of the line width-reduced luminence signal and the modulated colour subcarrier. The high-frequency luminence signal components and the modulated colour subcarrier are thus transmitted in time-division multiplex. In each line, a colour synchronisation signal (burst) is also transmitted. At the receiver end, the undelayed, wide-band luminence signal component and the wide-band luminence signal component delayed by one frame are used as luminence signal in alternating lines.

Title: Power semiconductor module with a plastic casing
Inventor: NEIDIG ARNO DIPL PHYS DR
IPC: H01L23/053
Filed: 1985-02-14
Abstract: The invention relates to a power semiconductor module with a plastic casing having clips moulded thereon and a ceramic substrate inserted as a baseplate. Modules of this type are screwed onto a heat sink. The rigid mechanical coupling arising in conventional modules, between the attachment point and the substrate pressing onto the heat sink, may result in fracture of the substrate or inadequate contact to the heat sink. It is proposed to couple the substrate (7) with the housing (1) via a thin lip (5, 17), resulting in more favourable contact conditions. <IMAGE>
