Title: Demountable roof for swimming pool - is assembled from arch sections with transparent areas and solar energy heated coils
Inventor: KOHNKE HANS JUERGEN DIPL ING
IPC: F24J2/04
Filed: 1975-09-09
Abstract: The swimming pool (1) has a domed roof which is assembled from arch sections (3) fixed together in a row. The sections are made of plastics and some are completely transparent.

Title: Fuel injection motor vehicle engine with swirl chamber - pumps air into swirl chamber by exhaust driven injection pump
Inventor: RENGER UDO DIPL ING
IPC: F02B27/00
Filed: 1975-12-19
Abstract: A cylinder (1) has a main inlet (7) and a swirl chamber (5) with a separate inlet (11). Fuel is injected (12) into the inlet pipe (10) leading to the swirl chamber where it is ignited by a sparking plug. Air is supplied to the swirl chamber inlet (10) from an injection pump (15). This has a nozzle (21) through which exhaust from the cylinder outlet (13) flows and which is surrounded by an annular air inlet (17). The flow of exhaust through the nozzle pulls air in through this and forces it out at above atmospheric pressure through an annular outlet (20). This increases the air to the swirl chamber at high loads and makes it possible for the whole of the fuel to be supplied through the swirl chamber.

Title: Electronic max. value monitoring device - generates signal when energy consumption exceeds adjustable value to operate load shedding relay after set delay
Inventor: BARTELS HELMUT
IPC: G01R21/133
Filed: 1976-04-28
Abstract: The electronic max. value monitoring device has adjustable waiting time and is controlled by pulses of a pulse counter proportional to the energy consumption. A time-base circuit generates the nominal values. Its response value is adjustable and its output delivers signals when maxima are exceeded. Loads are disconnected after an adjustable waiting time has elapsed. Waiting time generation is based on readings of a digital nominal value counter. It is digitally compared with a value adjustable by a coding switch so that, when a preselected value is reached, a bistable stage stores a signal. When a max. is exceeded, this signal is linked to the excess signal delivered by a comparator, and a load shedding relay is operated.

Title: System for preheating liq. fuels for combustion - using heat from liq. and vapour phase of fluid electrically boiled
Inventor: NEUMAYER HANS
IPC: H05B3/60
Filed: 1976-05-05
Abstract: The system for preheating liquid fuels for combustion is applicable to a wide variety of fuels which cannot be satisfactorily atomised at ambient temp. The heater is a thick-walled cylindrical vessel (1) of conducting material, with a pipe coil (2) for the fuel in the wall. The vessel is partially filled with an electrolyte (4) whose b. pt. is somewhat above the preheat temp. required. An airtight cover with a pump connection (7), press. gauge tapping (8) and immersible electrode (5) in an insulating cuff (6) is then fitted and the internal press. reduced as appropriate to the fuel. Current through the electrolyte then produces a mixture of liquid and vapour at boiling point; the lower specific heat of the vapour reduces thermal shock for the fuel entering at the top.
