Abstract: There is provided a lifting robot suitable for lifting and transferring a person. Especially there is provided a patient lift apparatus with collapsible vertical and horizontal columns that allows the apparatus to change its height and width. Specifically there is provided a patient lifting robot having a frame for lifting and carrying persons. The frame has adjustable length and width, since the frame comprises two vertically collapsible columns for adjusting the height of the frame, and one horizontally collapsible beam for adjusting the width of the frame.

Abstract: A modular flow reactor is formed of a plurality of modules, wherein each module comprises a body having at least one conduit passing therethrough, and wherein a plurality of said modules are aligned along a longitudinal axis such that said conduits of said modules are aligned to form a passage for fluid, wherein each module has a length along said longitudinal axis which is less than the length of the module perpendicular to the longitudinal axis. The modules are “slices” rather than “tubes” and a plurality of said modules can be aligned linearly so that the conduits form a tube.

Abstract: The invention relates to a method for compressing a compressible medium, in which at least two displacement elements, each having at least one limiting face extending helically in the cross section, are orbited in relation to each other under formation of at least one chamber, the volume of the chamber being changed by the orbiting movement, performing a cycle with a suction phase, a compression phase and a discharge phase, the chamber being opened and forming a suction chamber during the suction phase. It is endeavoured to improve the thermodynamic conditions during compression of a compressible medium. For this purpose, for the duration of the suction phase, the suction chamber is reduced by a volume limiting element in such a way that at the end of the suction phase the chamber has a volume of at least 90% of a maximum volume appearing during the suction phase.
