Abstract: A safety shut-off device is provided for a liquid gas system for vehicles and/or vehicle trailers, in order to avoid an inadvertent release of gas. The device includes an electromagnetic gas valve for supplying/shutting off the gas, an electronic unit for activating the electromagnetic gas valve, and a flow sensor for determining a current gas flow being discharged from a storage tank. Furthermore, the device includes an evaluation unit for comparing the current gas flow to a previous gas flow or to a gas flow which is indicated by the gas consumers and is to be expected. If, during use, the evaluation unit determines a current gas flow which differs by more than a maximum permissible rate of change from the previous gas flow or from an expected gas flow, the electromagnetic gas valve is activated via the electric unit in order to shut off the supply of gas.

Abstract: To improve on a vent plug system for a cell opening of a storage battery containing a plug element with an inner cartridge and a valve element, to where it is possible without the need for maintaining excessive physical tolerances to assemble it with a minimal number of components m simple fashion while still assuring reliable operation without any major effort, the plug element is provided as a cup-shaped unit with an outer contour shaped to fit into, and seal, the cell opening, with an internal cavity and with a gas port between the cavity and an outside surface. The inner cartridge is essentially cylindrical, has an outer contour shaped to permit insertion in the cavity of the plug element and is provided with a gas passage that opens into the cavity, while the valve element is a separate element retainable in the cavity by the inner cartridge and, as a function of the gas pressure, establishes a gas-flow connection between the gas passage of the inner cartridge and the gas port of the plug element.

Abstract: The invention concerns a plug arrangement for gas-tight closure of a cell vent of a storage battery. To provide a plug arrangement that to the greatest possible extent prevents acid from running out when a storage battery is tipped or turned and at the same time permits sufficient degassing and can also be produced economically, is easy to install and can be adjusted to different battery designs, this invention purposes a plug arrangement for gas-tight closure of a cell vent of a storage battery including a plug that can be used for a seal in the cell vent, an inside of the cell is connected by fluid mechanics to a hollow space made between upper and lower covers of a housing cover for acid deposition through a plug vent in a generating surface of the plug that has a two-way sealed membrane.

To provide a plug arrangement that to the greatest possible extent prevents acid from running out when a storage battery is tipped or turned and at the same time permits sufficient degassing and can also be produced economically, is easy to install and can be adjusted to different battery designs, this invention proposes a plug arrangement for gas-tight closure of a cell vent (2) of a storage battery composed of a plug (4) that can be used to seal the cell vent (2), whereby the inside (3) of the cells is connected by fluid mechanics to a hollow space (5) between the upper and lower covers (6, 7) of the housing cover (17) for acid deposition through a vent (10) in the generating surface (11) of the plug (4) that has a two-way sealed membrane (12).

Abstract: A cooking assembly has a main burner, a pilot burner mounted in it and having a vent, a gas valve having separate main and pilot gas outlets, and a main-burner controller including a temperature sensor on the main burner, a control unit on the valve capable of varying gas output from the main gas outlet, and a capillary tube connected between the sensor and the control unit. This controller can vary gas flow from the main outlet in accordance with the temperature of the main burner as sensed by the sensor. An electrical igniter on the main burner can be energized by a switch on the valve. A pilot-burner controller connected to the switch includes a thermoelectric sensor in the pilot vent and blocks gas output from the gas outlets when insufficient heat is detected by its sensor and the switch is not closed.

Abstract: A cooking unit has a ceramic cooking surface, a gas burner underneath the surface, a gas supply including a solenoid valve for feeding a combustible gas to the burner, and an electric igniter juxtaposed with the burner and electrically energizable to ignite the combustible gas issuing from the burner. An electricity supply is connected to the igniter and to the gas supply for electrically energizing the igniter whenever the valve is open and supplying gas to the burner. In addition an electronic controller connected to the valve and to the electric supply monitors current consumption of the igniter and closes the valve when the current consumption of the igniter indicates same is malfunctioning. The controller includes a digital circuit that is also typically operated by the user of the cooker to turn the burners on and off and control their temperatures and an analog circuit connected parallel to each other. At least one of these circuits controls opening and closing of the valve.

Thus the burners can heat the respective spots of the panel. An equipment plate in the housing spaced underneath the burner plate defines therewith an intermediate compartment also opening upward into the passage and defines beneath itself in the housing a lower compartment that is open to the outside at the front of the housing. Control equipment is mounted in the lower compartment of the housing along with a blower having an intake in this lower compartment and an outlet in the vent passage.
