摘要:
A household appliance, particularly a clothes dryer or a washing machine with an air-conducting and/or a water-conducting system of individual structural elements, through which suds, a gas flow, or the like can be conducted. The disinfection of water-conducting or air-conducting elements is simply successful if the surface facing the suds-conducting area of at least one of the structural elements is anti-microbially or bacteriocidally coated and/or the surface is anti-microbially or bacteriocidally doped, or if the surface facing the air-conducting area of at least one of the structural elements is anti-microbially or bacteriocidally coated and/or the surface is anti-microbially or bacteriocidally doped.
摘要:
A cooking appliance with a glass-ceramic hob having a plurality of cooking zones at least one of which cooking zones is designated as a rapid cooking zone. The cooking zones can be heated essentially by electrically operated heating devices, and the rapid cooking zone is formed by a ceramic hot plate integrated into the glass-ceramic hob.

The armored or bulletproof glass include a transparent plate laminate, which includes one or more transparent glass ceramic plates made from a green glass body of the Li2O—Al2O3—SiO2 system, optionally one or more additional plates made of plastic material, and optionally one or more glass plates. The glass ceramic plate preferably has a thermal expansion coefficient of −0.05×10−6/K to −0.10×10−6/K at 30 to 700° C. and a brightness value for transmitted normal light at an angle of 2°≧80 for a 4-mm thick plate. The transparent plate laminate preferably has a total of 4 to 8 plates and a thickness between 40 and 80 mm. A bulletproof vest, a fire prevention glazing, a fireplace viewing window pane, a cooktop, a magnetic storage plate or a substrate for semiconductor materials also advantageously include the transparent plate laminate described here.

A transparent plate laminate, which is used as armor or in a bullet-proof vest and which contains one or more of this glass ceramic plate together with optional glass and/or plastic plates, and a process for making the glass ceramic plate, are also described.
摘要:
A circuit arrangement for an electric appliance, having a control device and a power supply connected with an electric current supply connector for supplying functional units to be controlled of the electric appliance. A switching device for the separation of the power supply from the electric current supply connector at the primary side is provided at the electric current supply connector, which has a comparator, which can be activated by an electrical activation signal (A). It is used, for example, in electronically controlled household appliances.
摘要:
In a touch switch with a keypad 2, a tactual feedback of its operation, perceptible to the user, is said to be achieved. For this purpose a transducer 7 is provided, which upon a touching of the keypad 2 impressed a movement on the latter.
摘要:
A transport shield is provided for brittle glass and glass ceramic panels susceptible to scratching and fracturing to be integrated into a cooker, in particular as cooking surfaces. The transport shield remains permanently joined to the panel during installation, assembly and operation and is formed to act as a protector during mounting, a positioning aid, a separator, an elongation compensating medium and/or a sealing member and/or an inspection window in profiled panels.
摘要:
A gas radiation burner has a burner plate, and a safety element providing an ignition safety for non-burnt discharging gas for igniting gas or interrupting a gas supply. The safety element is formed as a temperature measuring resistance which contacts the burner plate via electrical conductors and is composed of a material of the burner plate.
摘要:
A process for separating mixtures of gases, vapors or liquids by diffusion through membranes. The object, the improvement of the degree of enrichment and of the separation characteristics, is accomplished by irradiating membranes with heavy ions perpendicularly or at an angle to their surfaces to produce latent nuclear traces. Without etching away the nuclear traces, the membranes are charged from one side with the mixture, a pressure differential is set-up, and the substances from the mixture are removed downstream from the other side, independently of the concentration difference, separating the components according to their rates of diffusion. The process has the further advantage that the components of the mixture to be separated are neither thermally stressed nor chemically changed. The process is suitable for the separation of a multitude of atomic and molecular mixtures.

The process for producing a transparent lithium aluminosilicate glass ceramic plate includes ceramicizing a green glass body of the Li2O—Al2O—SiO2 system using a ceramization program, which includes heating it, for the purpose of nucleation, to a temperature of 750° C.±20° C. and maintaining the temperature for 20±15 minutes, further heating the green glass body, for the purpose of ceramization, to a temperature of 900±20° C. and maintaining the to temperature for 20±15 minutes and then cooling to room temperature. The transparent plate has a thermal expansion coefficient (CTE) from −0.15×10−6/K to +0.15×10−6/K at 30 to 700° C. and a brightness value observed at an angle of 2° of ≧80 for a 4-mm thick plate for transmitted normal light.
