Abstract: A vacuum pump, in particular to a turbomolecular pump, has a pump inlet, a pump outlet and a pump space for a gas to be pumped arranged between the pump inlet and the pump outlet, and at least one cooling gas inlet for a cooling gas for cooling the vacuum pump, the pump further having one or more hollow regions for the cooling gas connected in a gas conducting manner to the cooling gas inlet and arranged outside the pump space, wherein the or each hollow region is bounded by at least one component of the vacuum pump to be cooled.

Abstract: A vacuum pump includes a pump inlet, a pump outlet, a rotor rotatable about an axis of rotation, at least one process gas pump stage for conveying a process gas present at the pump inlet from the pump inlet to the pump outlet, a motor space, and a drive motor which is arranged in the motor space, is configured for rotationally driving the rotor and which has a motor stator, wherein at least one gas path is provided for the process gas from the pump inlet to the pump outlet which leads through the motor space and which leads at least sectionally along the motor stator or through the motor stator.

Abstract: A clothes hanger bar is readily mountable and dismountable between a wall and a horizontal member, such as shower curtain rod or upper edge of a shower stall door. The hanger bar consists of a clothes-supporting portion for disposition horizontally having a bracket at one end that engages the horizontal member and also prevents sideways rotation. The other end of the rod is of Z shape with the clothes-supporting portion as an extended lower leg while the upper leg carries a wall-engaging member. The point of contact with the wall is above the point of intersection of the axis of the clothes supporting portion with the wall, so that the clothes-supporting portion is mounted in suspension and the weight of the clothes forces the wall-engaging member into firmer contact with the wall. The wall-engaging member may comprise a sleeve that can accommodate extension members of different lengths to adjust the effective length of the hanger bar.
