Abstract: The accommodating device for a portable PC (24), particularly for a notebook and for peripheral devices such as a printer (22) and telecommunications devices, comprises a principle power supply unit (26) which can be connected to a voltage network for generating required operating voltages for the peripheral devices from the voltage network, and a separate PC power supply unit (28) which can be connected to the voltage network for generating the required operational voltages for the PC (24). Both power supply units (26,28) are arranged underneath the PC (24). Further, a cooling air flow generator (34) generates a cooling air flow to cool the principle power supply unit (26). The PC power supply unit (28) is arranged in the cooling air flow.

Abstract: The present invention relates to a fire brick for a rotary kiln, provided on one or both large surface area portions with at least one concavity extending in the radial direction of the kiln, and opening on at least the face.The present invention further relates to a fire brick for a rotary kiln as described above, further provided with a steel plate having a concavity of dimensions which the sum of the depth of the concavity of said brick plus an expansion absorbing tolerance, and applied to a maximum surface area and lying over the concavity.The present invention still further relates to a fire brick for a rotary kiln as described above, further provided with board or asbestos, etc., on the face end of the steel plate.
