摘要:
A touch contact switch has a sensor key or button with a spatially extended, electrically conductive foam or flexible plastic or rubber body. The switch is operated by contact or approach. The sensor button essentially forms one pole of a capacitor and is electrically connected to an evaluating circuit of the touch contact switch, wherein switching is initiated as a result of a capacitance change in consequence of approach or contact. The sensor button can be bonded directly on a mounting plate of the associated electrical evaluating circuit or can be engaged by a pin or the like. The body can be flush to the underside of a cover, which forms or contains the contact surface. The body can include an opening along the longitudinal axis in which is insertable a LED.

An electronic control arrangement for an electrical heating appliance with several separately heatable electrical loads, particularly cooking points or hotplates, contains an electronic master switch, which has its own power supply. The master switch is followed by a control unit having for each electrical load in each case one control subunit. For each hotplate the control unit has a temperature sensor, which responds if the control unit becomes too hot at this point.

A three-terminal capacitor having high and low voltage electrodes coaxially aligned in a housing which serves as a ground plane includes a non-gaseous dielectric material filling the cavity of the housing. In the preferred embodiments, the dielectric is either a suitable oil or plastic. A source of voltage, that can be used to power for example an external electrical measuring device, can be generated by arranging a tertiary electrode proximate to the high voltage electrode and suitably selecting the ratio of surface areas of the tertiary and high voltage electrodes to produce sufficient current to power the device. Various embodiments of the capacitor also include and internal current transformer which provides a current signal indicative of series current flow through the capacitor. This current signal and the signal appearing on the low voltage electrode can be used to readily provide an indication of the amount of power supplied by a power transmission line to a load situated downstream of the capacitor.

A floor conveyor vehicle, particularly a stacker, has a brake device and an adjustable floor panel guided in the vertical direction by way of a device and is held in several working positions by a locking device. The floor panel is guided in the vertical direction by a lifting frame on a column arranged on one side of the vehicle. The floor panel is constructed as an operating plate for a parking brake and, with a pedal plate for a service brake, is swivellably linked to the lifting frame on axes.

A circuit arrangement (11) has an activating circuit (13) for a sensor element (12) of a touch contact switch, which in one embodiment of the invention contains a frequency generator (16). The frequency generator (16) generates a frequency-modulated activating signal (17), which is applied to the sensor element (12). In another embodiment the forming of the activating signal (17) takes place in a microcontroller (48), containing eventually the activating part (13) and or the evaluation of the signal. Through passing through a large frequency range for the activating signal (17), the influence of extraneous signals, even when using a lower signal voltage, is minimized.

A cooking device including a cooking area, a door for closing the cooking area and a lighting system for lighting the cooking area. The lighting system includes a light source and at least one reflector arranged in the internal space of the door, which reflects light from the light source into the cooking area. In order to reduce mechanical strain applied to the light source, it is arranged outside the door and emits light towards the reflector inside the door to be reflected into the cooking area.

The present invention provides methods and materials related to immediate early genes. Specifically, the invention provides isolated immediate early gene nucleic acid, cells that contain isolated immediate early gene nucleic acid, substantially pure polypeptides encoded by immediate early gene nucleic acid, and antibodies having specific binding affinity for a polypeptide encoded by immediate early gene nucleic acid. In addition, the invention provides cDNA libraries enriched for immediate early genes cDNAs, isolated nucleic acid derived from such cDNA libraries, and methods for treating conditions related to a deficiency in a neuron's immediate early gene responsiveness to a stimulus.
