Title: Method for controlling heating boilers having multistage burners, and a control device for carrying out the method
Inventor: BRENNER LOTHAR
IPC: F23N5/02
Filed: 1981-03-13
Abstract: The "DESIRED value" formed by means of resistors (15, 18, 19) is compared with the ACTUAL value measured at the total feed sensor (10), and the positioning motor (2) is set rotating in the event of a difference. When the DESIRED value is undershot, the switching means (3) are moved left in the direction of the cam-operated switch (5). After the latter has been switched, the first stage of a burner is started. If the quantity of heat supplied, as measured at the total feed sensor (10), does not effect a change in the positioning command and a shutdown of the positioning motor (2), after a specific time the second stage of the burner is started by the switched cam-operated switch (6). Should a temperature difference still be present, the cam-operated switch (7) then required opens the butterfly valve of the water system leading to the second boiler. The switch (8) sets the first stage of the second burner operating. In order to avoid continuous oscillation, the switch (6) switches off the second stage of the first boiler. As a result, the positioning motor (2) rotates further without being decreased. It provides the necessary link for the oscillation between the first stage of the second boiler and the second stage of the first boiler. This control device permits an arbitrary number of heating boilers to be used automatically for multistage heating operation consistently and in a way which saves energy. <IMAGE>

Patent DE-3128751-A1 (DE)
Title: Stop for windows and french windows
Inventor: DELECKER WILLY-MAX EDUARD
IPC: E05C17/18
Filed: 1981-07-21
Abstract: Patent Application P 3128751.4 describes a stop for windows and french windows, consisting of a retaining rod which is firmly screwed to the window or french-window frame by means of a retaining-rod fastening angle so as to be pivotable in the latter. Seated on this retaining rod is a housing which slides to and fro on the retaining rod when the window or french window is opened or closed. Located in the housing is a retaining peg fastened to the cover which is held freely on the housing under the pressure of the cover-holding spring. Depending on the opening position of the window or french window, the retaining peg engages into a retaining notch located on the retaining rod and thus detains the window or french window. By means of a cover lifter located on the housing, the cover, together with the retaining peg located on it, can be raised and the retention is cancelled. In the closed state of the window or french window, the retaining peg is seated in the first retaining notch. This ensures that an intruder cannot swing open the window or french window, and his free entry into the house is thus prevented. Sheet 1, Figure 1, of the drawing illustrates clearly a front view of the stop for windows and french windows in its device, with the window or french window closed. <IMAGE>
Patent DE-3132512-A1 (DE)
Title: Simplified device, without any losses caused by the principle of operation, for ridding electrical or electronic one-way switches of a high power loss stress while they are switching on and off as well as ridding them of an increased cut-off voltage stress in conjunction with their switching off
Inventor: BOEHRINGER ANDREAS PROF DR ING
IPC: H03K17/0814
Filed: 1981-08-18
Abstract: Simplified device, without any losses caused by the principle of operation, for ridding electrical or electronic one-way switches of a high power loss stress while they are switching on and off as well as ridding them of an increased cut-off voltage stress in conjunction with their switching off. With respect to the best possible utilisation of their electrical limit data and taking into account their thermal stress and the losses caused thereby, electrical and electronic one-way switches may not be subjected to any considerable power loss stress while they are switching over. As a consequence of this, switching-on relief inductors are used which limit the rate of current rise after switching on. The energy which is stored in these switching-on relief inductors can (according to German Patent Application P3113655.9) be fed back into the supplying DC voltage system without any losses resulting from the principle of operation. If such a device is combined with a switching-off relief network in accordance with one of the German Laid Open Specifications 2649385, 2650673 or 2710938, then the one-way switch is rid of any high power loss stress while it is changing over, without any additional losses resulting from the principle of operation. However, in this case, premature charge reversals of the switching-off relief capacitors may be noticeable in an interfering (disturbing) manner. The device according to the invention specifies solutions by means of which such premature discharges are reliably prevented. This is achieved, by way of example, in Figure 37 in that the additionally inserted ring-back reverse diode (177) prevents premature discharges and the additionally inserted changeover enabling thyristor (178), which can be switched off, enables correct charge reversal. <IMAGE>

In order, in a device of this type, to achieve an especially good transmission of heat to the parts to be heated, it is proposed, according to the invention, that the heating element have a profiling corresponding to the key belonging to the lock, and that the heating plate be embedded into a heat-insulating body which leaves only its top side free.
Patent DE-3136367-A1 (DE)
Title: Monostable multivibrator, particularly for control devices of electrical heating charge regulators
Inventor: ROHN KLAUS DIPL ING
IPC: H03K3/284
Filed: 1981-09-14
Abstract: In monostable multivibrators having a duration of the metastable phase which depends on a control voltage, the phase is switched to the stable phase by an electronic switch (2) becoming conductive after the end of a discharge of a capacitor occurring during the metastable phase. In many cases, monostable multivibrators in which the duration of the metastable phase depends precisely on the value of a control voltage are required for electronic circuits, particularly for control devices of electrical heating charge regulators. To achieve this aim, the multivibrator branch (1, 3) containing a resistor (3) carrying an auxiliary voltage and blocked during the stable phase is connected to the output of an amplifier (4), to which the control voltage is applied. In addition, the capacitor (10) determining the control potential of the electronic switch (2) in the multivibrator branch blocked during the metastable phase is connected, on the one hand, to this resistor (3) and, on the other hand, to a regulating circuit (11) which keeps its charging current at a constant value. <IMAGE>
Patent DE-3137566-A1 (DE)
Title: Device for heat exchange
IPC: F28D1/06
Filed: 1981-09-22
Abstract: For the exchange of heat on containers with spherically curved walls, e.g. for cooling liquids, tube coil systems have previously been used. These have to be adapted to the respective surface curvatures. Additionally, they only come into contact with the container wall in a linear manner. The degree of efficiency during heat exchange is thus unsatisfactory. The invention now uses heat exchanger plates made up of two sheets, the one sheet being completely flat and channels for the heat exchange medium being impressed in the other sheet. Such heat exchanger plates have a transverse incision from at least one longitudinal side or are provided with relief slots. As a result, they can easily be adapted to spherical surface curvatures. In this case, the flat side comes snugly into contact with the container wall. As a result, a surface contact is achieved with a considerable increase in performance compared to tube coil systems.
