    摘要: A diving bell type control rod of sodium bond type. The control rod including a plurality of control elements each comprising a pellet chamber for packing B.sub.4 C pellets and disposed in a cladding tube, an intermediate plug disposed above the pellet chamber, an upper chamber formed above the intermediate plug, a vent tube allowing the pellet chamber to communicate with the upper chamber while penetrating through the intermediate plug, upper and lower vent holes formed in upper and lower two stages in the cladding tube at the upper chamber, a sodium inflow port opening to the upper surface of the intermediate plug, and a sodium introduction tube extending from the sodium inflow port to a position below the lower end surface of the intermediate plug while penetrating through the intermediate plug.

    摘要: A method for converting a multifilament bundle of a synthetic material into a sliver and an apparatus for effecting the method. The apparatus comprises: a feed roller device for feeding the bundle; a draft roller device consisting of a pair of draft rollers, the peripheral speed of which draft roller device is higher than that of the feed roller device, for stretch breaking the filaments in the bundle between the feed roller device and the draft roller device; and an apron belt, belted between one roller of the draft roller device and the intermediate portion of the feed roller device and the draft roller device, which is wound around the other draft roller. The broken filaments are smoothed between the apron belt and the other draft roller so that the evenness of the sliver thickness is improved and the uniformity in quality of the spun yarn obtained from the sliver is also improved. Accordingly, the method and apparatus has advantages when a multifilament bundle of a synthetic material is converted into a sliver at a high speed of not less than 200 m/min.
