Title: Rotary piston engine ignition system - avoids ignition by incandescence and uses alternating spark plugs
Inventor: DIETERLE HANS
IPC: F02P15/02
Filed: 1973-09-04
Abstract: In order to permit a cooling phase between each spark, two spark plugs are fitted to the combustion chamber and regulated by a conventional contact breaker distributor to give an alternative spark at each working phase. The contact breaker cam is set very slightly out from its radial symmetry to compensate for the different plug positions. Three or more spark plugs could be used on the same principle. Alternatively four spark plugs could be used with two ignition units so that two spark plugs would be ignited simultaneously and alternating with the other two. Three spark plugs could also be used, one pausing while the other two simultaneously ignite.

Title: Afterburner with combustion chamber and heat exchanger - has cylindrical combustion chamber arranged coaxially with heat exchanger with tubes
Inventor: WILKES ERNST
IPC: F23G7/06
Filed: 1973-09-28
Abstract: The afterburner system is used for purification of waste gases and especially for elimination of smoke and smelling compounds. The afterburner unit is highly compact because the combustion chamber is arranged within the heat exchanger. The preferred version of the combustion chamber is cylindrical and the heat exchanger encloses the combustion chamber coaxially as a cylindrical envelope. The heat exchanger has a cluster of pipes. The central combustion chamber accommodates the afterburner flame. Hot gases from this tubular combustion chamber are ducted into an annular space around the combustion chamber and from there into the annular chamber which accommodates heat exchanger tubes. The tubes are held on support plates which impart a twisted path to the hot gases before they reach the outlet. Raw waste gas enters the heat exchanger and passes through the tubes and joins the flow into the burner.

Patent DE-2406530-A1 (DE)
Title: Restrictor valve with elastic valve tube - has varying wall thickness of tube to produce uniform bending stress
Inventor: REICH HEINZ ING
IPC: F16K7/07
Filed: 1974-02-12
Abstract: A restrictor valve has an elastic valve tube held inside a rigid sleeve by two flanged rings. By pressurizing the space between the sleeve and the valve tube, the tube is deflated towards its axis, thus closing the valve. Since the areas where the tube is held by the flanged rings experience the highest bending moment, it is the region where the tube fails first. To prevent this weakness, the tube wall is tapered with increasing thickness towards the ends. This produces an approximately equal bending stress over the whole tube length, thus increasing its useful life.
Patent DE-2421397-A1 (DE)
Title: Safety valve - ignition button for gas burning appts - has thermocouple sensor generating current to activate internal valve control electromagnets
Inventor: PEHAU PIERRE
IPC: F23Q9/14
Filed: 1974-05-03
Abstract: A gas safety valve with flame sensor thermocouple has a push button top linked to a shaft via springs to a metal plate forming the keeper of a small electromagnet. A similar plate forms the keeper of a second electro magnet. Both electromagnets are activated by the current generated by the thermocouple sensor. To ignite the gas at some distant point, the button is depressed against springs opening the gas valve. Ignition of the gas varies the temperature of the thermal probe at the flame source and the current generated retains the keepers against the electromagnets allowing gas flow to continue. Should the gas flame be extinguished the immediate direction of current flow in the sensor de-activates the magnets and spring pressure closes the valve.
Patent DE-2421518-A1 (DE)

Title: Drying of malodorous organic materials - partly air-dried in vortex pipe-system before chemical treatment
Inventor: MENGE WILHELM
IPC: F26B25/00
Filed: 1974-05-25
Abstract: The malodorous material is introduced into an annular piping system, having a vortex mechanism and a circulating hot air stream, generated by a blower, acting on the piping system. The material floats in the air-stream, until its moisture content and, in certain cases, its particle size, have been reduced to a predetermined value. The air-stream, emerging from the annular system and containing the material, is passed, by way of a separation-unit, to a sewage-field, where the malodorous components, retained by the air-stream, are converted into substances without objectionable odour, e.g. by spraying with a carbonate suspension and treatment with chlorine or sulphur dioxide.

Filed: 1974-08-20
Abstract: A press for the prodn. of cakes of soap includes a cross with four dies which can be turned in steps from a blank feed station to a press station, a discharge station and a die cleaning station. The rectangular dies are open at both ends and have closed sides which leave a gap all round against the circumference of the press mould halves which enter them. The cross with the four dies is simple to mfr. The dies are made of standard sections and need not be machined on the inside. There is little waste of soap material because a small gap between die and mould is enough to fix the cake of soap securely.
Patent DE-2444053-A1 (DE)
Title: Vacuum cleaner electric cable storage drum - has series wound spiral springs to maximise rotary movement in restricted space
Inventor: FAHLEN KARL LENNART
IPC: B65H75/48
Filed: 1974-09-14
Abstract: Space is restricted but an adequate length of cable must be contained for drawing out and automatic recoiling. Two spiral springs wound in opposite directions are employed. The outside of the first spring is anchored to the body of the vacuum cleaner and its inner end to a freely rotatable shaft. The inner end of the second spring is anchored to the shaft and its outer end is fixed to the cable drum. A pull on the cable winds up the spring from the outside tending to rotate the shaft and to wind up the spring from the outside. Thus the available spring movement of the two springs is added together.
