Title: Prefabricated roof frame for the construction of buildings
Inventor: SEITZ KARL
IPC: E04B7/02
Filed: 1984-01-25
Abstract: The prefabricated roof frame, for the construction of buildings, for different roof shapes and roof pitches, comprises a principal-girder part (1) and a roof-girder part (2), adapted to the roof shape and roof pitch in question, which is placed on top of the principal-girder part (1). The principal-girder part has parallel upper-chord and lower-chord edges (3, 4) and, on its bearing ends (13, 14), upper-chord slopes (5, 6) which are trapezoidally inclined from the upper-chord edge to the lower-chord edge. The ends (9, 10) of the roof-girder part (2) preferably adjoin said upper-chord slopes with the same angles of inclination. In order to connect a support and a bearing end of the roof frame, the support exhibits a connecting bar which projects from the bearing surface of the support and engages in a through-hole in the bearing end of the roof frame, which through-hole is filled in when assembly has been completed. Canopy structures can be suspended on the connecting bar by means of reinforcing bars, which structures are supported on an outer end surface of the roof-frame end and of the support. <IMAGE>

Title: Auxiliary arrangement for an optoelectronic module housing
Inventor: HABERLAND DETLEF DIPL PHYS DR
IPC: G02B6/38
Filed: 1984-02-17
Abstract: Auxiliary arrangement for an optoelectronic module housing (G/K), comprising a glass fibre (S/L) having a tip (S), the so-called taper (S), and a stiff tube (R), specifically comprising the tube (R) which surrounds, protects and aligns the glass fibre (S/L) and, for its part, is to be plugged through a wall opening (W) of the module housing (G/K), and a section of the glass fibre (S/L) which is mounted in the tube (R) in such a way and - at least in the vicinity of the first tube end (VR) to be directed in the module housing (G/K) onto the optoelectronic component (D), specifically at at least one point - is fastened to the tube (R) in such a way that the glass fibre tip (S) still projects out of the tube (R) at the first tube end (VR). In order to provide the taper (S) at the first tube end (VR) by pushing the taper through the tube (R), e.g. by means of compressed gas, while reducing the risk of contamination and/or damage to the taper (S), the glass fibre (S/L) is surrounded in the vicinity of the taper (S) by a spacer element (AK) whose outside diameter is smaller than the inside tube diameter given at a location remote from the first tube end (VR). <IMAGE>
Patent DE-3409873-A1 (DE)
Title: Control arrangement
Inventor: KOETTER WOLFGANG DIPL ING
IPC: F15B11/16
Filed: 1984-03-17
Abstract: In a control arrangement (13), several directional control valves (14, 15, 16) are connected to a neutral circuit (17). In the flow position, a first directional control valve (14) controls the entire pressure-medium flow, delivered by a pump (10), to a single-acting consumer. A pressure-medium flow reduced by an adjustable restrictor (33) arranged in the neutral circuit (17) passes to the directional control valve (16). This pressure-medium flow is always greater than the pressure-medium flow passing to the directional control valve (15), the latter pressure-medium flow being adjustable by a restrictor (22). But the restrictor (22) also influences the control pressure at an operating valve (24), which is able to shut off the passage (23). Thus the working pressure at the consumer connected to the directional control valve (15) and the control pressure at the operating valve (24) can be adjusted with one and the same restrictor (22). The control arrangement (13) can easily be adapted to consumers connected to the directional control valve (16).

Patent DE-3430749-A1 (DE)
Title: Swath widening and data reduction in synthetic aperture reconnaissance radar (SAR)
Inventor: BRAUN HANS MARTIN DR
IPC: G01S13/90
Filed: 1984-08-21
Abstract: Until today, SAR was considerably restricted in its swath width, owing to the requirement that, for a desired geometrical resolution in the direction of flight, a minimum pulse repetition frequency had to be chosen, automatically fixing the maximum swath width previously possible. The method described here allows this swath width to be expanded n times without substantially increasing the data rate in the transmission of the SAR raw data to the ground. This is significant since, without this increase in swath width, the transmission rate of the SAR raw data is at the limit of current technology with the systems which can be realised today. The method utilises the fact that the Doppler history for targets from different distance ranges has slight differences. It allows the echoes from different distance ranges (ambiguity zones) to be temporarily interfolded and transmitted to the ground as just an echo. On the ground, this method allows the one echo to be broken down again into the echoes from the various distance ranges, it being possible to achieve a good signal-to-noise ratio.

Patent DE-3438159-A1 (DE)
Title: Process and apparatus for generating ozone
Inventor: HEUSER CLAUS DIPL ING
IPC: C01B13/11
Filed: 1984-10-18
Abstract: The bleaching and oxidising agent ozone is produced in Siemens ozone generators. The efficiencies of conventional ozone generators are low, since the temperature of the gas to be ozonised is too high in the discharge gap. The present process according to the invention uses a heat exchanger for additional cooling of the reaction gas in the discharge gap by convective heat transport. The gas to be ozonised flows through a discharge gap, which is short in the direction of gas flow, at high gas flow velocities and is subsequently cooled in a heat exchanger. To generate sufficiently high, industrially useful ozone concentrations, the gas flows several times in circulation through the discharge gap. For this purpose, it is driven by a fan. Using the process according to the invention, large quantities of ozone relative to m<2> of electrode area can be produced per unit time at high efficiencies.

Patent DE-3514346-A1 (DE)
Title: A calibration fluid having a constant CO2 content
Inventor: ZANDER ROLF PROF DR MED
IPC: G01N33/96
Filed: 1985-04-20
Abstract: For the purpose of calibrating and standardising CO2 analysis instruments for measuring carbon dioxide in liquids, an aqueous solution is described whose overall CO2 content does not change in contact with atmospheric air. In addition to physically dissolved carbon dioxide (CO2), the liquid contains bicarbonate (HCO3<->) and carbonate (CO3<-->), the original sample weight concentration of carbonate ranging, depending on the overall CO2 content, from 0.8 to 0.9% of the square of the bicarbonate concentration. The concentration of physically dissolved carbon dioxide establishing itself generates a CO2 partial pressure which corresponds to that of atmospheric air, which precludes the absorption or release of CO2, so that the pH of the solution remains unchanged.
