Abstract: CIRCULATING BED CELL            Abstract of the Disclosure In order to control the size distribution of electroconductive particles that constitute a particulate electrode in an electrochemical cell, the particles are extracted and subjected to elutriation.  The flow of elutriating fluid is such that particles larger than a given size settle against the flow of fluid while other particles are carried along by the fluid flow and then are returned to the cell after separation, if necessary, from the elutriating fluid.

Abstract: ABSTRACT OF THE DISCLOSURE          In a convergence device for the three primary-color projection type color television system with three cathode-ray tubes, it is known to use two separate cores respectively for dynamic and static convergence correction. In the present invention a single core is used and the core is provided with eight pole pieces aligned along the vertical, horizontal and two diagonal axes and each pole piece has a winding therearound. The vertically and hori-zontally aligned pole pieces are used to correct horizontal and vertical dynamic convergence respectively.  The diagonal-ly aligned pole pieces are used for both the horizontal and vertical static convergence correction by producing magnetic fields horizontally and vertically.  The construc-tion is much more simple, and the correction of the dynamic and static convergence which is required as a result of a difference in incident angles of electron beams projected to a screen can easily attained.

Abstract: ABSTRACT OF THE DISCLOSURE: This invention relates to a tape transport mechanism, particularly an improved contact winding tape transport system modified to protect it against tape transport disturbances occasioned by mechanical impacts. A shock-resisting coupling means is provided which is allocated to the reel carriers and which allows slow movements of the carriers toward and away from a drive capstan during normal working of the mechanism but prevents sudden movements of the carriers induced by mechanical shocks for instance. Piston/cylinder assemblies and magnetic rope/drum arrangements are disclosed as such shock--resisting means. The transport mechanism can be used advantage-ously in portable apparatus, preferably in magnetic tape recorders and especially in video cameras.

Abstract: ABSTRACT OF THE DISCLOSURE         Control apparatus for a hydraulic lift which permits a pair of lifting cylinders to be raised equal amounts and which permits lowering of the lift without expenditure of energy and without the necessity of the pressure source being in service.  Two single acting lifting cylinders are powered by a common pressure source.  Two valves in the lines from the pressure source to the cylinders are rigidly interconnected and are attached to a cable which engages pulleys on the lift.  Deviation of the lift from a level position alters the position of the end of the cable and operates the valve, in such a manner as to permit flow of fluid to one cylinder only to return the lift to a level position.  Non-return valves are situated in the pipe between the valves and the cylinders to prevent return flow of fluid from the cylinder.  A manually operated valve is connected to lines from the cylinders to the reservoir to control downward movement of the lift.
