Title: Switching circuit for motor vehicle - reduces intensity of rear-window brake-lights by switching in resistors after given delay
Inventor: ROEBEN KLAUS
IPC: B60Q1/44
Filed: 1980-12-29
Abstract: The switching circuit switches the brake-lights behind the rear window of a vehicle from normal intensity to reduced intensity during long braking periods. To attain this reduction in intensity, the rear-window lights are switched via a delayed-response relay and resistors (or transistors), i.e. after a given time, e.g. 1-2 secs, the resistors are switched in to reduce the current supplied to the light. When the brake pedal is released, the relays are de-excited so that the process repeats itself when the brake pedal is next operated. The normal rear brake lights (low down near the wheels) are unaffected by this switching.

Title: Method and device for operating a monovalent heating installation
Inventor: GOEBEL PETER
IPC: F25B30/04
Filed: 1981-07-14
Abstract: A heating installation, in which fuel heat is used according to the absorption principle for room heating and/or service-water heating, works as a heat pump above a preselected outside-air temperature. At lower outside-air temperatures, the heat generated by the same primary energy carrier is transmitted directly to the heating medium. In order to improve the efficiency of such an installation, the coolant (16) expelled from the expeller (3) of the absorption heat pump is, before entry into the liquefier (6), rectified in the rectifier (5) in exchange with coolant-rich solvent (17). At the same time, the heating medium is additionally heated by heat exchange in the rectification by means of a return cooler (19) arranged in the head of the rectifier (5) as well as with smoke gas in the expeller (smoke-gas aftercooler 21). <IMAGE>
