Title: Coded data enhancer systems
IPC: H04L25/49
Filed: 1973-08-06
Abstract: 1435929 Inserting parity bits BELL & HOWELL CO 6 Aug 1973 [4 Aug 1972] 37152/73 Heading G4C Apparatus for inserting parity bits into a stream of n bit binary words at terminal 12 (Fig. 1) each associated with n clock pulses from a source 48 includes circuitry 87 (Fig. 2) for deriving for each word a parity bit and circuitry for deriving from n clock pulses from the clock 48 n+ 1 clock pulses to allow accommodation of the parity bits into the stream. As described 7-bit NRZ words are clocked into a first shift register 36. Parity generator 87 comprising exclusive NOR gates 88, exclusive OR gates 89, AND gates 92 and NOR gates 93 derives a signal at terminal 96 if the shift register contains an even number of "1" bits (check after amendment). The shift register 36 is connected via seven gates 51 to a second eight-bit shift register 37, the output from the parity generator being fed via an eighth gate 51 to the first stage of the register 37. The clock pulses from clock 48 of frequency f are fed together with feedback signals from a counter 161 (Fig. 3) to a phase detector 101 connected via an amplifier stage 102 to a voltage controlled oscillator 103 deriving at terminal 147 a clock signal having a frequency 8f. This signal is fed to two counters, a divide-by-7 counter 167 and the divide-by-8 counter 161. The output signal 81 of counter 167 which is consequently a frequency 8/ 7 f is used to read-out the second shift register 37. Parallel transfer of data from the first shift register to the second occurs when a count of four in counter 167 coincides with a count of seven in counter 161, this condition being detected by a NAND gate 155.

Title: A bobbin stripping and winding device for use with a loom
IPC: B65H73/00
Filed: 1960-10-28
Abstract: 949, 949. Bobbin stripping and winding devices for use with looms. RUTI MACHINERY WORKS Ltd. Oct. 28, 1960 [Oct.29, 1959], No. 37199/60. Headings D1F and D1J. A bobbin stripping and winding device for use with a loom includes a holder for receiving a substantially exhausted bobbin from the loom, a stripper for removing remmants of weft from a held bobbin and means of winding said bobbin with fresh weft whilst on said holder. A used bobbin in a shuttle 1, Fig. 1, is forced out by a wound bobbin from a supply magazine 3. The used bobbin passes down a slideway to a point where grippers 10a on a conveyer belt 10, carries the bobbin up to an assembly point 6 from which the bobbins are transferred by a feed lever 5 to a winding device 4. The waste yarn on the bobbin is first removed by rotating the bobbin in a direction B, Fig. 2, to unwind the yarn thereon, a rotary brush 19 being moved against the bobbin to assist in the clearing of the yarn which is then passed into a suction pipe 22. During the unwinding period the yarn . supply 13, extending to a wound bobbin 24, passes over a guide roller 21a that holds the yarn away from the bobbin that is being cleared. The wound bobbin 24 corresponds to the bobbin 11 in Fig. 1. When the bobbin being unwound has been cleared, it is rotated in the opposite direction A, the brush 19 moves away from the bobbin, and the guide-roller 21a moves to the position 21. This movement of the guide-roller moves the yarn supply to the line 13 and the bobbin holder is given a brief axial displacement to cause hooks 17,18, on a thread-finder ring 16, to catch the yarn and commence the winding operation. When the bobbin is fully wound it moves to the position 24 and the wound bobbin already at the position 4 is moved into the magazine 3, Fig. 1. A feeler 15 determines whether the yarn waste has been removed at the end of an unwinding operation. If the waste has not been completely removed the feeler controls a mechanism adapted to separate the not fully cleared bobbins from the cleared bobbins. Instead of the single winding device 4 there may be two, one for clearing and the other for winding a bobbin.
