Patent GB-156606-A (GB)
Title: Improvements in and relating to winding machines for yarn and the like
IPC: B65H54/54
Filed: 1921-01-06
Abstract: 156,606. Barber-Colman Co., (Assignees of Colman, H. D.). May 12, 1916, [Convention date]. Winding-machines; stop-motions; thread guides; creel arrangements.- In a yarn-winding machine, wherein the yarn mass being wound is pressed against the rotating means or retained in spaced relationship thereto by movable, means which coacts with a projection on the means for supporting the yarn mass, the movable means comprises a lever which so engages the projection that it may alternatively press the yarn mass against the rotating means or oppose a forcible initial or renewed contact of such mass and means; this lever with the parts cooperating therewith constitutes improvements in the mechanism described in Specification 156,605. The invention is described as applied to a machine for winding yarns from bobbins a. Fig. 1, on to tubes b. A lug 12, Fig. 2, on an arm 6 which carries the tube engages a notch 11 in a spring-pressed lever 8 when the cheese is in contact with the driving- drum. The arm 6 is operated to remove the cheese from the drum upon exhaustion of the yarn by means described below whereupon the lever is drawn rearwardly by its spring and the lug 12 rides on the surface 10 and thus prevents the return of the cheese. For piecing, the arm is swung by the operative so that the cheese is in the position shown in dotted lines on the right hand side of Fig. 1, and is retained in such position by the engagement of a lug with the lever 8. To reset the parts the lever 8 is drawn forward manually to bring the upper wall of the notch into contact with the lug 12, and is then allowed to move rearwardly under the action of its spring, a dash pot 26, which checks the action of the spring, in co-operation with the manual operation opposing forcible movement of the cheese towards the drum. Upon exhaustion of the yarn a looped link 14 depending from the arm 6 is moved into the path of an oscillating hook 18 by an arm 24 on a spring-controlled shaft 20, whereupon the arm 6 is operated to remove the cheese from the drum. The arm 24 is normally withheld from the link by the engagement of the yarn with a feeler device 21 on the shaft 20 which is turned into position to receive the new yarn by the engagement of the lever 8 during its backward movement with an arm 27 on the shaft 20. If the cheese has attained the desired diameter it moves a gauge 32 as it is thrown out of the operative position and thereby moves a stop 40 behind the lever 8 and prevents its movement. A guide 28, Figs. 1 and 3, is provided with a flaring entrance 29 and a hook 30 which serves to hold the yarn from a new bobbin in position to be engaged by the feeler fingers as they are moved into the operative position. Defective yarn masses may be rewound by placing them on a stand 47, Fig. 5. arranged on the floor beneath the bobbin holder A and leading the yarn therefrom between guide-wires 49 and through a tension device 51.

Title: Dynamic ram with on-chip ECC and optimized bit and word redundancy
Inventor: BARTH JOHN EDWARD JR
IPC: G11C29/42
Filed: 1997-05-08
Abstract: A DRAM having on-chip ECC (30) and both bit and word redundancy that have been optimized to support the on-chip ECC. The bit line redundancy features a switching network that provides an any-for-any substitution for the bit lines in the associated memory array. The word line redundancy is provided in a separate array section (20), and has been optimized to maximize signal while reducing soft errors. The array stores data in the form of error correction words (ECWs) on each word line. A first set of data lines (formed in a zig-zag pattern to minimize unequal capacitive loading on the underlying bit lines) are coupled to read out an ECW as well as the redundant bit lines. A second set of data lines receive the ECW as corrected by bit line redundancy, and a third set of data lines receive the ECW as corrected by the word line redundancy. The third set of data lines are coupled to the ECC block, which corrects errors encountered in the ECW. The ECC circuitry (30) is optimized to reduce the access delays introduced by carrying out on-chip error correction. The ECC block (30) provides both the corrected data bits and the check bits to an SRAM (40). Thus, the check bits can be externally accessed, improving testability of the memory chip. At the same time, having a set of interrelated bits in the SRAM (40) improves access performance when using multi-bit access modes, which compensates for whatever access delays are introduced by the ECC. To maximize the efficiency of switching from mode to mode, the modes are set as a function of received address signals. <IMAGE>
