Abstract: A process for the continuous manufacture of seamless tube by confining a selected length of metal strip (11) in the form of a tube (25) and with at least two longitudinal abutting edges (26) and heating (31) to completely melt a selected length of such tubular form to form a seamless tube and cooling (32) the formed seamless tube. The cooling is preferably in a controlled atmosphere (50) of nitrogen and the temperature is reduced to about 700°F before further processing takes place. In a preferred process the material is a single strip of metal formed (20) into a tube with only one longitudinal seam and it is moved (20) continuously through a mould heated by induction heating (31) selectively controlled to cause the tube to preheat (31A) to a selected temperature and then be subjected (31B) to a temperature bringing the metal to its molten state to form a seamless tube and while the seamless tube is moving it is cooled (32) downstream from the melting zone solidifying the metal and bringing it to a selected temperature before exiting the mould.

Abstract: An electrostatic latent image (21) on a photoconductor(11) of an electrophotographic device (10) is developed by a grey scale monocomponent nonmagnetic development system using a combination of AC and DC bias voltages applied to a developer roller (13) and a monocomponent nonmagnetic developer applied to the developer roller (13) by an adder roller (14). The developer (17) comprises a mixture (45) of toner particles (46) charged to one polarity and transparent beads (47) charged to the opposite polarity, by triboelectric charging in bulk in an alternating field between the two rollers (13) and (14), rather than by friction contact with apparatus (12) surfaces. The adder roller (14) applies the charged mixture (45) to the developer roller (13) for developing the latent image (21) in an electric field to an image density determined by the magnitude of the DC bias. A DC bias may be applied to the adder roller (14), especially to provide a gradient relative to the DC component (50) of the developer roller (13) bias for driving the bulk charged mixture (45) onto the developer roller (13). A doctor blade (15) is usable to smooth the toner (17) into a selective thickness layer on the developer roller (13). The developer roller (13) may have an uncoated semiconductive surface layer (27), or one covered by a non-conductive coating (28). The system provides greater uniformity of triboelectrical charging and reduced sensitivity to surface contamination.

Abstract: In a method and apparatus for address translation for translating a 64-bit virtual address into a real address, the 64-bit virtual address comprises a segment number (60), a page index (62) and a page offset (64). When this virtual address is translated into a real address, high order bits of the segment number are first input to a hash generation circuit (34) to obtain a hash address of a link table (22), and this link table (22) is retrieved by an address obtained by adding lower order bits of the segment number as an offset to obtain tag information of the virtual address and a base address of a page table (26). Next, the tag information of the virtual address obtained in this manner is compared with the original segment number, and the base address of the page table (26) is judged as correct when they coincide with each other. The page table (26) is retrieved by an address obtained by adding a page index (62) as an offset to this base address to obtain a page frame number, and the virtual address is obtained by combining the original page offset (64). According to this construction, address translation can be carried out at a higher speed while maintaining compatibility with the 32-bit virtual address.
