Title: Process for the ultra-violet stabilisation of synthetic resins
IPC: C08K5/00
Filed: 1964-11-18
Abstract: High molecular weight thermoplastic polycarbonates of aromatic dihydroxy compounds are stabilized against ultra-violet radiation by adding a benzophenone derivative and/or a benzotriazole derivative to the polycarbonate after it has been made weakly acidic to an extent corresponding to that produced by adding 0.001-0.5 wt. per cent of phosphoric acid.  The weak acidity may be produced by adding an acid or an ester having an acid reaction at an elevated temperature to a weakly basic or neutral polycarbonate.  Suitable acids and esters are phosphorus acids and boric acid and their esters, e.g. orthophosphoric acid, metaphosphoric acid, mono- and di-phenyl phosphates, tri-isooctyl and tri-decyl phosphates, phenyl metaphosphate, boric acid, the boric acid ester of hexane-1,6-diol, and boron phosphate.  The benzophenone and benzotriazole additives are known U.V.-absorbing additives, e.g. 2-hydroxy-4-methoxy-, 2,21-dihydroxy-4-methoxy-, and 2,21-dihydroxy-4-octoxy-benzophenone and the 2-(21-hydroxy-51 - methyl - phenyl)-, 2 - (21-hydroxy - 51 - tert. - butyl - phenyl)-, and 2 - (21 - hydroxy - 31, 51-dimethyl-phenyl)-derivatives of benzotriazole. Amounts of 0.1-5% of the U.V.-absorber may be used.

Title: Apparatus for indicating error in digital signals
IPC: H03M13/19
Filed: 1964-12-02
Abstract: 1,056,029. Checking arrangements. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 2, 1964 [Dec. 30, 1963], No. 48890/64. Heading G4A. Apparatus for indicating error in a digital signal in which the information is repeated completely at least once comprises a first comparing device for comparing the digits which correspond with one another and for indicating the number of pairs of inconsistent digits, a second comparing device for comparing, in accordance with a predetermined code, the digits which do not correspond, and an output device responsive to both comparing devices for indicating error in the signal. The code may be any Bose-Chaudhuri cyclic code, the particular embodiment using a singleerror-correcting Hamming code of six data bits and four parity check bits. Each bit is present in the message twice, in true and complement form respectively. The twenty bits of the message are stored in a buffer shift register 182 (Fig. 2B, not shown) from which the true bits are passed to a true shift register 200 (Fig. 2A, not shown) and the complement bits to a complement shift register 236 (Fig. 2E, not shown). Corresponding bits in these last two shift registers are compared in ten modulo-2 adders feeding inverters (Fig. 2C, not shown) the ten inverter outputs all going to each of three majority logic blocks which produce outputs if at least 1, 2 and 3 respectively of the inverters have produced outputs thus indicating the number of true-complement pairs containing an error. Four modulo-2 adders (Fig. 2A, not shown) perform parity checks on the true bits, the outputs of the adders being ORed together to produce a true error signal and also being supplied directly and after inversion to a set of ten AND gates the outputs of which insert ONES in corresponding stages of an errorcorrecting shift register 376 (Fig. 2B, not shown). Another four modulo-2 adders (Fig. 2E, not shown) perform parity checks on the complement bits, the adder outputs being ORed together to produce a complement error signal. If there are no errors the contents of the true shift register are shifted to an output line 387 (Fig. 2E, not shown). If there are errors in both true and complement bits, and an output from the " 1 " majority logic block but not from the " 2 " block, and also in the case where there is an output from the " 3 " block, an alarm is given indicating a non-correctable error and the output line is blocked. Otherwise, if there is a true error but no complement error, the contents of the complement shift register are shifted out, inverted, and passed to the output line, and if it is not the case that there is a true error and no complement error, the output line is supplied from a modulo-2 adder the two inputs to which are fed from the true shift register and the error-correcting shift register shifted out in synchronism. Thus the latter effectively inverts the erroneous bit in the former. Actually the true, complement and error-correcting shift registers are always shifted out together, but those outputs not required are blocked.

In automatic bobbin-exchange apparatus having mounted on an overhead rail system above the spindles of a spinning-frame grippers for full and empty bobbins, cutting means are associated with the grippers to sever the yarn between the spindles and the grippers for the full bobbins after the full bobbins have been doffed and empty bobbins donned. As shown, rails 4, 5 suspended from a crane by ropes 6, 7 respectively carry grippers 10, 15 for empty and full bobbins. A cutting bar is attached to the line of grippers 15 for full bobbins, levers 24 connecting it to a continuous shaft 21 connected at 21 to some of the grippers. The shaft can be rotated to swing the cutter by a handle 23. The rails 4, 5 can be separately raised and lowered, rope 7 passing through a hole in rail 4. Each of the grippers 15 comprises a hollow rubber cylinder connected at 18 to a continuous air-pipe 16. When the cylinders are inflated, the bobbins are gripped; when they are vented, the bobbins are released. At the end of a set, the crane is so positioned that the grippers 15 fit over the filled bobbins, and the cylinders are inflated to grip the bobbins. The crane is now moved to fit the grippers 10 each previously fitted with an empty bobbin over the spindles and remove the grippers 15 to the front of the machine. The yarns extending between the filled bobbins are held down by the empty bobbins, and the cutter is operated. The filled bobbins are then released.
