Patent DE-2604176-A1 (DE)
Title: Switching system for automatic gas firing system - monitors burnt gas flow with temp. sensor with time delay
IPC: F23N5/18
Filed: 1976-02-04
Abstract: The switching system is used in an automatic gas firing system provided with flame monitor whose burner has no blower. The current supply to fuel valve actuator is interrupted in absence of flame after a delay time. The flame monitor keeps fuel supply valve open for flame present before lapse of delay time. The apparatus used with automatic firing system is reliable and readily installed. The system has burnt gas return flow monitor with temperature sensor (43) with time delay. After this sensor has responded the power supply (65) is disconnected for a specified period. Alternatively the gas flow can be restricted. The burnt gas return flow monitor is automatically tested before or during each startup.

Title: Exhaust emission control for IC engine - has gas probe esp. for oxygen to help regulate mass ratio of mixture fed to engine
Inventor: WESSEL WOLF ING GRAD
IPC: F02D41/14
Filed: 1976-02-19
Abstract: Exhaust emission control for internal combustion engine uses an exhaust gas probe, esp. an oxygen probe to determine the composition of the exhaust gas and hence help regulate the mass ratio of the fuel mixture supplied to the engine. The output signal from the probe is fed to a variable gain amplifier for controlling the mixture adjusting unit. The signal is fed via a threshold circuit (3) whose control position determines the integration direction of the amplifier. The time lapse between two successive operations of the threshold circuit is detected by the charging or discharging of a store whose charging condition influences the time constant of the amplifier (4).

Title: Continuous prodn. of rolls of wound material - uses band material wound on sleeve formed from same material
Inventor: MERGELL WOLFGANG
IPC: B65H18/22
Filed: 1976-06-15
Abstract: Procedure for continuous prodn. of rolls of web of different length and width with or without a sleeve takes place in unwinding phase and winding on phase. The unwinding phase is carried out automatically in a free space corresponding to the form of the roll on a mandrel which is inserted sidewards in the free space. When the material reaches a predetermined number of layers the mandrel with the layers of material is transferred to a winding on station in which the mandrel is removed from the layers of material. The so formed sleeve is then used to wind on a further web of material by a system of guide rollers and a running endless guide belt. When a predetermined length of the band material is wound on the sleeve the web is cut through and the finished roll removed from the winding station.

Title: Floor tiles made of expandable clay and organic material e.g. wood - in which clay fills voids formed by organic material during baking
Inventor: SPORKENBACH GUSTAV ADOLF
IPC: C04B38/06
Filed: 1977-05-10
Abstract: Porous and/or cellular ceramic panels, esp. floor tiles, are mady be mixing expandable clay with materials (I) which can be burned out and baking. During or after baking the temp. is raised so the cavities formed by the burning of materials (I) are at least partly filled by the expansion of the clay. The temp. is pref. increased rapidly, so the pores in the surfaces of the panel are partly or completely closed by sintering; and the panel or tile may be clamped to produce a desired skin thickness; when the desired thickness of the outer skin on the panel is obtd., the clamping pressure is reduced or released. Method increases the mechanical strength of the tiles so they may be directly employed with no further mfg. operations. Conventional materials (I) are wood, coal, paper, cork, rice husks, and foamed polystyrene; on baking, these materials leave cavities which provide good thermal insulation but impair the mechanical strength of the tiles. The invention improves the strength.
