Abstract: A double layer forming fabric for use in a paper-making machine has a warp ratio of at least six strands and a shute ratio of at least twelve strands. The warp strands bind with the lower layer at locations distributed according to a satin weave pattern whose ratio is equal to the warp ratio; the warp strands bind with the upper layer at locations distributed according to a pattern whose aggregated ratio is equal to the warp ratio and which is constituted by the association of several weave patterns each having a warp ratio lower to 6 strands. There are at least two shute strands of the upper layer between two successive points where a warp strand comes down from the paper contacting face across the upper layer and then comes up again, respectively.

Title: Digital data processor with fault-tolerant bus protocol
Inventor: HENDRIE GARDNER C
IPC: G06F11/16
Filed: 1982-09-30
Granted: 1987-04-09
Abstract: A fault-tolerant computer system provides information transfers between the units of a computing module, including a processor unit (12) and a memory unit (16) and one or more peripheral control units (20, 24), on a bus structure (30) common to all the units. Information-handling parts of the system, both in the bus structure and in each unit, can have a duplicate partner (14, 18, 22, 26). Error detectors check the operation of the bus structure and of each system unit to provide information transfers only on fault-free bus conductors and between fault-free units. The computer system can operate in this manner essentially without interruption in the event of faults by using only fault-free conductors and functional units. Arbitration circuits of unusual speed and simplicity provide units of the computing module with access to the common bus structure according to the priority of each unit. The units of a module check incoming and outgoing signals for errors, signal other module units of a detected error, and disable the unit from sending potentially erroneous information onto the bus structure.

Title: Method and device for manufacturing a cored yarn
Inventor: VIGNON LOUIS
IPC: D02G3/36
Filed: 1984-05-15
Granted: 1987-07-09
Abstract: A twist is imparted to fiber slubbing (1) exiting from drawing rollers (2) by means of twister (4). Oriented, parallelized fibers (F) are applied to rotating fiber slubbing (1) in front of or within twister (4), the fibers (F) wrapping themselves around core thread (1). Because of these fibers (F), the twist of fiber slubbing (1) no longer unravels completely after twister (4), so that a spun thread (12) of great strength is obtained. The feed of fiber (F) to fiber slubbing (1) occurs by means of rotating feed element (8). It has a circular perforated surface (9), behind which a negative pressure is maintained to keep fibers (F) on the surface. The oriented, parallelized fibers (F) exit from drawing rollers (10) and are conveyed to perforated surface (9). The rotating fiber slubbing (1) comes into contact with surface (9) and then draws fibers (F) from surface (9). So that fibers (F) remain oriented and drawn during transfer, the speed of movement of perforated surface (9) is greater than the rate of feed of drawing rollers (10) and less than the circumferential speed of fiber slubbing (1).
