Title: Detection and correction of errors in information words
IPC: G06F11/10
Filed: 1972-07-10
Abstract: 1402613 Digital data error correction INTERNATIONAL BUSINESS MACHINES CORP 10 July 1972 [10 July 1971] 32158/72 Heading G4A Digital electric apparatus detects and corrects errors in information words read from a data store 1 (e.g. of monolithic semi-conductors), the words each having check bits.  Each word has 16 data bits and 6 check bits (e.g. Hamming code) which bits allow the correction of single errors and the detection of double errors. A word is read out of the store and, of a double error is detected, the word is read out again, If the word has only sporadic errors it will probably be correct or only have one, correctible error when read-out again, but, if at least one error is permanent, then the or one of the permanent errors is corrected as described below using circuit KS5 and the sporadic error is later corrected in a known manner by circuit FKS3. Correction of Permanent Error.-In a first step CPU of the processor generates a first data pattern, the first bit being 1 and the rest zero, 6 check bits are generated for these, and the 22 bit word is stored in the location having a double error. Subsequently the stored word is read out and applied to error correction circuit FKS3. If a single error is detected, counter Z9 is incremented and a 1 passes to shift register 10 which is shifted once each checking step. In a second step the CPU generates a 16 bit data pattern where the second bit is 1 and the rest are 0 and the process is repeated. This continues for 16 steps (or however many data bits there are in the word), after which register 10 contains a pattern of 0's and l's (Fig. 4, not shown) used for correction in circuit FKS5 comprising n + k Exclusive OR circuits. A read only store FWS11-FWS16 generates checkbits P from the pattern in SR10 and applies them to correction circuit KS5.

Title: Improvements in or relating to fluid pressure operated blowers for cleaning the tubes of steam generators and the like
IPC: F28G3/16
Filed: 1934-11-13
Abstract: 447,199. Soot blowers. MOSES, R. 1., 37, Bassingham Road, Wembley, Middlesex, and IVOR POWER SPECIALTY CO., Ltd., 418, Strand, London. Nov. 13, 1934. No. 32690. [Class 99 (ii)] A soot blower comprises a nozzle 3 which is mounted on the end of a blower tube 1 concentric with a pressure-fluid supply pipe 2 and is advanced into and withdrawn from its operative or blowing position by a rotatable shaft 31 locating a longitudinally - movable gear wheel 27 which engages a gear 22 on a collar 8 secured on the inner end of the blower tube. The collar 8, which is provided with an end plate 21 engaging a groove 29 in the gear 27, is recessed at 17 to receive a nut 16 which engages threads 15 on the pipe 2 and is formed with a lip or projection 25, Fig. 2, to be engaged by a lip 26 in the recess 17. The collar 8 also carries a freely mounted ring 36 which is provided with a cam 37 for actuating the spindle 38 of the pressure-fluid supply valve 45 and with a lug 42, Fig. 3, adapted to co-operate with a pair of driving pins 43 on said collar. In operation, assuming that the blower tube is in its inoperative position with the collar 8 at the extreme right-hand end of the conduit 2, the shaft 31 is rotated by a shaft 33 and gears 32 to effect rotation of the collar 8 and also rotation of the nut 16 and ring 36 by engagement of the lips 25, 26 and the lug 42 with one of the pins 43 respectively. Consequently the nut 16 moves to the left projecting the blower into its operative position, in which position the valve 45 is opened by the cam 37. Rotation or oscillation of the blower tube through practically 360‹ without longitudinal movement may now be effected by rotation of the shaft 31 in the opposite direction until the lip 26 engages the other side of the lip 25, the valve 45 remaining open until the second pin 43 engages the lug 42, and the blower then returned to its inoperative position by continued rotation of the shaft 31 in this direction. By providing a single pin 43 on the collar 8 the valve will be retained open during a complete rotation of the blower tube ; similarly, the angle of free rotation of the blower tube may be restricted by providing the collar with a second lip 26. As shown the valve 45 is slidable in a chamber 52, into which leakage of pressure fluid is permitted, located in the pressure-fluid supply casing 49, and it is bored axially at 54 to receive the spindle 38, the upper end of which is fluted, and counterbored at 56 to provide a seating for a ball 57. The valve is normally held closed by the fluid pressure acting on the flange 46 of the valve and also by the pressure in the chamber 52 acting on its upper face ; when the spindle 38 is raised however the ball is moved away from its seating to permit release of the pressure in the chamber 52 and consequently easy opening of the valve during continued movement of said spindle.
