Patent DE-2844037-A1 (DE)
Title: Water or aircraft propulsion device - is rotating body of revolution, rotated with helical grooves angled rearwards about axis to act as screw
Inventor: BECKESCHAT REINHOLD
IPC: B64C11/00
Filed: 1978-10-09
Abstract: The water- or aircraft propulsion device is for fitting to a conventionally powered rotating shaft (2). It comprises an elongated solid of revolution (1) coaxial with the shaft, pref. oval with the smaller end downstream, into whose surface have been cut three or more- pref. helical grooves running parallel (3).

The device may have a shroud.
Patent DE-2844089-A1 (DE)
Title: Flat iron protective circuit - with trigger switch and mercury switch in handle for preventing fires by deposition in wrong position
Inventor: WIENANDT REINHOLD
IPC: D06F75/26
Filed: 1978-10-10
Abstract: In addition to the protective control circuit for domestic flat irons described in the Parent Patent No. 2806808, the handle of the flat iron is equipped with a mercury switch or other switch which responds to a tilting motion. This extra switch is connected in parallel to the trigger operated switch in the handle which is depressed to switch on the heat. Release of the trigger cuts off the heat because the mercury switch is also in the off position in the ironing period. The mercury switch will close its contacts only if the flat iron is deposited on edge. i.e. at right angles to the ironing position. This provides a simple means of ensuring that fires cannot be caused by depositing the flat iron in the wrong position. If the price is no object, the trigger switch can be replaced by a sensor.

Title: Safety circuit on electro-medical instrument - has control panel with logic circuit blocking functions until tests are successful to prevent incorrect use
Inventor: FARIN GUENTER ING GRAD
IPC: A61B18/12
Filed: 1980-02-02
Abstract: The safety circuit is for an electrical medical instrument and provides protection against incorrect operation. The connected instrument can only be activated when the necessary operating measures have been taken based on criteria relevant to safety. The control panel of the instrument (18) is fitted with a logic circuit (20). The logic circuit prevents the instrument from being activated when the mains (1) is switched on. It also prevents a built-in therapy clock (29) from functioning until all the test questions have been actuated. The pushbutton actuator elements operate signal lamps (5,6,7) which come on if the necessary criteria are fulfilled. The switching conditions of the pushbuttons are stored in a logic circuit until the instrument is switched off or until a mains cut-out exceeds a given time interval.

Title: Emergency telephone with pushbutton switch=over - changes from high-ohmic quiescent state to low-ohmic speak state
Inventor: KONOPKA PETER ING GRAD
IPC: H04M11/04
Filed: 1980-02-06
Abstract: The emergency telephone uses a code to change its mode from quiescent to voice. A sprung pushbutton changes the telephone (NRT) from high ohmic to low ohmic in order to establish a voice connection. The line is briefly interrupted to mark the change in mode. The interruption is accomplished by interrupting the hold-current circuit of a switch (A) using a contact (T1) belonging to the pushbutton. The resistance of the switch and its parallel capacitor (C) determine the duration of the interruption. Once the switch has returned to normal, the mode changeover switch (B) is operated by another contact (T2) belonging to the pushbutton and the low-ohmic state produced.
