A low pressure suction side refrigerant to liquid refrigerant heat exchanger, located in the refrigeration circuit in such a way that the sensor (and external equalizer tube, if applicable) is located downstream of the low pressure refrigerant outlet of the heat exchanger, provides for effectively eliminating both the superheat and flash gas loss regions of the evaporator which in turn increases the mass flow through the evaporator and increases the refrigerating capacity of the evaporator at very little increase in compressor power thereby providing for increased system efficiency for refrigerating or cooling purposes. On the heating side, heat rejection capacity of a heat pump is increased even more dramatically because of the heat reclaim of the flash gas loss heat, which provides for even greater efficiency increases for heating applications.

The present invention involves a cover for a spraying device of a robot which is formed from a polymer with enhanced residue retention properties. The polymer may be processed to increase the surface energy of the polymer. For example, the polymer may be subjected to a corona treatment in order to increase its surface energy. The corona treatment process may be performed on the polymer as received, prior to cutting or otherwise manipulating the polymer. Also, the polymer may be embossed to provide the enhancement. To assemble the polymer into a robot cover, the polymer as received may be cut into individual sections for assembly. The sections may then be assembled to one another by heat sealing the sections together. The heat sealing provides a bond between the individual sections of polymer that secures the individual sections together to create the robot cover. The polymer may also be formed into tubular sections for securing to the spraying device.

The invention relates to a multi-layered radiation converter, a radiation detector comprising such a converter as well as a radiation-based imaging system using such a detector. Each converter layer (32) in the radiation converter is adapted for interaction with incident radiation to cause the emission of electrons into drift holes defined in the converter layer. The drift holes of one converter layer (32-1) are staggered with respect to the drift holes of another converter layer (32-2). By mutually shifting the converter layers such that the drift holes of two different layers are no longer well-aligned, but rather staggered with respect to each other, the effective conversion area will be increased, and the probability of incoming radiation passing through the stack without interaction with the converter layers will be significantly reduced. In this way, high absorption efficiency for incident radiation inside the multi-layered converter structure is ensured, while still maintaining transparency for emitted electrons through the drift holes.
