Title: Method for regulating a central-heating boiler
Inventor: NOACK ROLF DR
IPC: F24H9/00
Filed: 1988-09-23
Abstract: In order to obtain a maximum saving of energy, but eliminate the occurrence of condensate, a regulating method is proposed in which a mixing valve (16) is switched completely from the return pipe (17) to the flow pipe (15) and the burner (18) is run on full load in a starting circuit until a minimum value of the boiler water temperature (at thermostat 13) slightly above the dew point is reached, with a low or normal heat demand, i.e. at desired flow values below the set value of sensor (20), the desired flow temperature is regulated by the mixing valve (16), and with a high heat demand, i.e. at desired flow values above the set value at sensor (20), the mixing valve (16) is switched completely towards the heating boiler and the burner (18) is run in modulating fashion with adjusted burner load. <IMAGE>
Patent DE-3832688-A1 (DE)
Title: Awning with solar cells
Inventor: PHILIPP THORSTEN
IPC: H02S30/20
Filed: 1988-09-27
Abstract: Awnings of the previous type of construction have been used, up until now, as protection against wind and inclement weather and as advertisement carriers. The latter usage, however, has been ruled out. They could be used only by the additional laying of 220-V-power lines and by installing lamps on the awning. The novel arrangement is intended to make it possible for the awning and the illumination to be regarded, in future, as a self-contained unit. The arrangement is composed essentially of the aluminium basic body (1) on which a special translucent film (3) is tensioned. This body is to be closed towards the bottom by a base panel (2) consisting of, for example, acrylic. Said base panel serves both as a visual termination of the arrangement and to receive the accumulator (4) of the lighting and controlling unit (5-6). Located in the upper region is the solar-cell module for generating power (8). The arrangement thus permits a friction-free mounting of the entire body without any additional installation work being necessary. By virtue of the controlling unit (5), fully automatic switching on and off of the lighting unit is additionally achieved. <IMAGE>

Patent DE-3835873-A1 (DE)
Title: Apparatus for the production of fancy yarn
Inventor: NOELLE WOLFGANG
IPC: D02G1/16
Filed: 1988-10-21
Abstract: In the known apparatuses for the production of fancy yarn, the distribution and nature of the points of increased thread accumulation can be varied in terms of individual spacing, distribution and dimensions to only a greatly restricted extent. Moreover, the changes in the thread pull take place abruptly, with the result that the risk of thread breaks increases. The invention is intended, in particular, to improve the possibilities of variation. The apparatus for the production of fancy yarn, with a constant guidance of the core thread and with a variable guidance of the fancy thread through an air-texturing nozzle, with the fancy thread being drawn out to form thread loops before it runs into the air-texturing nozzle, is characterised in that the amplitude of the thread loops is varied according to a predetermined programme. The diverse possibilities of variation afforded by the apparatus according to the invention lead to highly varied fancy yarns.

Patent DE-3911254-A1 (DE)
Title: Method for establishing the complex measuring capability of homodyne network analysers
Inventor: EUL HERMANN-JOSEF DIPL ING
IPC: G01R27/28
Filed: 1989-04-07
Abstract: The patent application relates to methods for establishing the complex measuring capability of network analysers operating in a homodyne mode. Both one-port and two-port measuring devices are treated in which the signal is detected by means of a linear mixing process. Using the proposed methods, it is possible to eliminate the defect of the homodyne detection process that it does not supply any direct information on amplitude and phase of the measured signal, by means of measuring arbitrary unknown standards. The required number of different unknown standards depends, inter alia, on the complexity of the measuring device used. One of the proposed methods operates without any standard.
