摘要： An improvement to a cathode used in an electrorefining or electrowinning of copper. The cathode has a solid copper head bar (2) with a horizontal groove (6) on its undersurface. The upper edge (9) of a stainless steel flat sheet has several holes (13) along its width and is vertically inserted into the groove. The stainless steel sheet is then mechanically attached to the copper head bar (2) by pressing the copper head bar against the stainless steel at the perforated points along the head bar. To increase the joint strength, the stainless steel sheet may be welded to the copper head bar as its upper edges at the underside of the head bar.

摘要： The present invention is concerned with an electric downhole heating system (10) for formation heat treatment in the field of oil and gas production. The heater (10) contains separate wiring chamber (12), heating chamber (16), and cooling chamber (14), the latter being inserted between the wiring chamber (12) and the heating chamber (16). The heat treatment is carried out by inserting the heater (10) in a borehole to be treated. A gas, preferably nitrogen or air, is brought to the heater with a hose or tube (24). The gas goes through the wiring chamber (12) and cooling chamber (14), and is heated by following a tortuous path in the heating chamber (16) before it is expelled from the heater (10).

摘要： A system for measuring the charge distribution on a photoreceptor plate which has been exposed to X-ray radiations to form an image of an object thereon is dis­closed. The system comprises a transparent sensor electrode adapted to be positioned over the photoreceptor plate, means for scanning a pulsed laser beam through the transparent sensor electrode to discharge the photorecep­tor surface charge pixel-by-pixel and so induce a cor­responding voltage on the sensor electrode to be read by a suitable read-out device, such sensor electrode being of sufficient width so as to achieve good capacitive coupling with the region around the area to be discharged by the laser, and means for moving the sensor electrode or the photoreceptor plate step by step or continuously trans­versely of the laser scanning direction for reading out the image impressed on the photoreceptor surface.
