    摘要: A switch contact arrangement for a power switch is provided with a device for increasing the contact force acting between switch contacts. The device includes a cavity which is made in a stationary conductive element of the switch contact arrangement in such a manner that the direction of the current in the conductive element adjacent to the stationary switch contact runs essentially perpendicular to the longitudinal direction of the conductive element and therefore essentially parallel to the direction of current in an associated displaceable conductive element. The above-mentioned arrangement is suitable for low-voltage power switches with a selective form, whereby the switch contacts thereof allow a short-circuit current to be guided without premature opening.

    摘要: A method and a device for ascertaining and mapping data representing the optical imaging properties of an eye of a person, in which n different test images are displayed individually in succession on an electronically controllable monitor unit, are seen by the person from a settable viewing angle and at a settable distance, and are identified by means of an input comprising: a) ascertaining a characteristic viewing angle value at a given distance, at which a first probability for correct identification of the test images is achieved, b) ascertaining a characteristic distance value while maintaining the ascertained characteristic viewing angle value, at which a second probability for correct identification is achieved which is greater than the first probability, c) repeating steps a) and b).

    摘要: A circuit breaker has at least one housing having at least one opening, and at least one pair of contacts located in the housing, the contacts of the pair of contacts being mobile in relation to each other for opening and closing an electric circuit. An open-pore metal foam (20) is interposed between at least one of the pairs of contacts and at least one housing opening (11), the metal foam being electrically insulated from the current-carrying elements of the circuit breaker (1). An open-pore metal foam (20), produced of a zinc base alloy or aluminum base alloy, can be used as a cooling structure for the dissipation of heat from switching gases that are produced by an electric switching process.
