Abstract: A locking device is used for doors of cabinets or cupboards and, more parularly, for doors of modular cupboard systems. In order to create an operationally reliable, inexpensive locking device which is suitable for narrow counterstops and which permits an installation independently of the fixing side, as well as an inexpensive conversion when the fixing side is changed, the locking device is given a bipartite construction with a handle positioned in the vicinity of a door plate and a bolt mechanism operable by a tumbler. The device has a first door plate area receiving the handle and a second door plate area. A locking movement, initiated by the handle, is subject to a deflection, preferably of approximately 90.degree., in the direction of a counterstop and a closed or open position of at least one locking element in a cabinet or cupboard-side receptacle is obtained.

Abstract: An apparatus for determining the relative positions of power outlets within a multi-outlet electrical circuit and, specifically, for determining the first occurring power outlet in a multiple-earth-neutral power system in which earth and neutral wires are interconnected at a distribution point. The apparatus incorporates circuitry for generating a current pulse and probe means for injecting the pulse into a wiring loop which extends between neutral and earth contact terminals of each of the power outlets. The probes are also employed for detecting the voltage drop which occurs along the wiring loop as a consequence of the current flow through the loop, and circuitry is provided for generating a signal which is representative of the voltage drop along the wiring loop.

Abstract: A fan slide-in unit, module or chassis of the type used for cooling electronic assemblies. The fan slide-in unit constructed in modular manner having a plurality of fan installation locations arranged in rows and which comprises two half-shells made from substantially acoustically inert material. The number and location of the individual fans can comply with the needs of the particular individual, the installation locations left free being made air-impermeable. The ready electrical connection possibility provided for each installation location permits an easy changeover. In addition, the mounting of the individual fans in the half-shells takes place in solid-borne sound-decoupled manner, so that essentially there is only the noise caused by the air flow. The fans used are controlled in unitary manner by a manually adjustable control block, which can be guided in a temperature or parameter-dependent manner.
