Patent DE-2318064-A1 (DE)
Title: Hot-drawing branched containers - using semi-circular gas burners and heat-insulated tool
Inventor: DIETRICH JOHANNES
IPC: B21C37/29
Filed: 1973-04-06
Abstract: When enlarging the side opening in tubes or containers for e.g. high-tension switchgear filled with an insulating-gas, gas burners are used to heat the metal and a drawing tool with a heat-insulated zone is used to reduce heat-loss through the tool. When a T-junction is required in a tubular container, an elliptical hole is made and a conical drawing tool pulled through the hole to make a circular outlet collar. In the initial heating stage, two semi-circular burners heat the metal round the hole and, when the collar is partly drawn, the first set of burners is replaced by a second pair which heat the collar. The number and direction of the jets in the burners are designed for uniform heating to the correct temp. The drawing tool is a three-part tool where the conical core is fitted with a wire cage which forms a gap between the core and the outer cap of the tool, the resultant air gaps acting as a heat-insulator. Alternatively, the surface of the core can be machined so that it consists of horizontal or vertical grooves that form air gaps between core and cap.
Patent DE-2329903-A1 (DE)
Title: Liquid fuel cracking system - by compression and catalyst with exhaust as carrier gas
Inventor: AUGUST PAUL DIPL ING DR
IPC: F02M27/02
Filed: 1973-06-12
Abstract: A liquid fuel for I.C. engines is converted into a gaseous fuel by applying pressure, heat and a catalyst in conjunction with an inert carrier gas (exhaust gases), in two successive stages. The first stage initiates the cracking of the fuel carried by the inert gas during a short period, assisted by a piston compressor. The second stage completes the cracking in a catalyst connected to the inlet manifold of the I.C. engine. This method produces an exhaust gas which is non-toxic and free from CO, NO and other toxic matter proscribed by the antipollution laws of some countries. The fuel is converted into high-octane gas which, combined with layered charging, allows a higher compression ratio and results in greatly reduced fuel consumption.

Title: Delay time switch for car interior light - with electronic circuit to maintain light for set time after doors closed
Inventor: HIMMELHEBER ERNST
IPC: B60Q3/02
Filed: 1974-03-27
Abstract: The time delay circuit is a compact solid state system incorporating a flip-flop and a special resistor which decreases in resistance as it warms up. The circuit is coupled in parallel to the door switches and requires only two contacts i.e. between the light cable and earth. When the interior light is switched on by opening the door, the change in potential on the input of the circuit causes it to switch to a conducting mode, which it retains until the resistor has warmed sufficiently to switch the circuit back to the non-conducting mode. The time interval is chosen to enable the user to have sufficient time to fasten the seat belts, or to leave a garage at night. The system uses no current when in the non-conducting state.
