Abstract: Packing for a column for treating solid particles by direct contact between an ascending gas current and solid particles flowing countercurrent by gravity within the packing. The packing has an ordered structure, consisting of superposition of at least two stacking elements (1,12), each comprising shaped elements (2, 9) arranged parallel between themselves and with regular spacing, said spacing providing a passage opening between two neighboring shapes between 3 and 20 times, preferably 7 and 15 times, the average granulometry of said particles, and the vertical projection of the shaped elements completely covering a horizontal section of the column. This packing is very specially recommended in the presence of particles with a granulometry greater than 2 mm or having mediocre flow characteristics.

A gas insulated electrical apparatus is connected to a container for a cleaning solution including a volatile solvent. A conduit connects the container for the cleaning solution to the gas insulated electrical apparatus, and another conduit, including a filter apparatus, connects the gas insulated electrical apparatus to the container for the cleaning solution, for returning the cleaning solution, which has been used to wash the gas insulated electrical apparatus, to the container for the cleaning solution. Vacuum or pressure producing apparatuses may be provided for aiding in the transfer of the cleaning solution.

Abstract: A numerical controller having a memory device for storing a profiling program composed of a series of data blocks, each of which designates an incremental rotational amount of an oval workpiece and an incremental feed amount of a tool slide, and a digital computer for reading out the data blocks one by one from the memory device when no rough grinding is instructed, so as to provide, based upon a read-out data block, interpolation data of feed pulses which are to be distributed for tool slide feed in connection with feed pulses to be generated for workpiece rotation. In rough grinding, the digital computer reads out a predetermined number of the data blocks and accumulates profiling data included therein so as to provide interpolation data based upon the accumulated profiling data, thereby shortening processing time for providing the interpolation data in rough grinding.

Abstract: An electrode per bit (E/B) structure type charge transfer device in which N storage cell each consisting of a barrier region and a storage region are driven by N-phase clocks, one of N storage cells being empty and the remaining N-1 cells storing signal charge packets. The N-phase clocks are biased to a low level for storage and pulsed to a high level for transfer. The N storage cells are successively rendered in the transfer mode in the direction opposite to the charge transfer direction so that the empty cell is shifted to the adjacent preceding cell in the direction opposite to the charge transfer direction every time each of the N-phase clocks is pulsed. After one cycle of the N-phase clocks, all the signal charge packets are shifted to the succeeding cells respectively. A multiplexed electrode per bit (ME/B) structure type charge transfer device also is disclosed which employs the E/B structure and is operable by the clocks with small number of phases, providing a CCD memory with a large capacity.

Abstract: A hydraulic brake booster mechanism for use with an open or circulating fluid pressure system includes a divider valve for the fluid flow interposed between a source of continuously circulating fluid pressure and a power steering mechanism, a control valve operatively associated with a brake pedal for applying the brakes, and a change-over valve actuated by means of the displacement of the divider valve upon the failure of the source to deliver the fluid pressure from an accumulator to the control valve for assuring an emergency application of the brakes.

Abstract: An arrangement for semiconductor power components in an installation, in which at least one semiconductor power component is placed between contact pieces and is enclosed in a housing exhibiting an insulator and connecting pieces. The arrangement includes current conductors which promote safety and prevent explosion by absorbing electric arcs formed in the installation. The current conductors are placed laterally adjacent to the contact pieces and annularly surrounding the latter, separated from the interior wall of the insulator by narrow gaps. Additional embodiments of the present invention employ reinforcing elements around the housing, and explosion guards around the housing, thereby further enhancing installation safety.
