Patent GB-1278237-A (GB)
Title: Data handling systems
IPC: G06F11/10
Filed: 1970-09-04
Abstract: 1278237 Error handling INTERNATIONAL BUSINESS MACHINES CORP 4 Sept 1970 [30 Sept 1969] 42417/70 Heading G4A A data handling system includes an (n-k) stage feedback register arranged for operating in relation to an (n, k) cyclic error code, and means for forming logical functions of (n-k) sub-combinations of c code integers (where n>c>n-k) and applying such functions to respective stages of the register. A computer communicates with peripherals via a control unit, data transfer between computer and control unit being parity checked, and that between control unit and peripherals being checked and corrected using an (n, k) shortened cyclic error-correcting code as follows using the Fig. 1 apparatus in the control unit. For encoding, a k-bit word (from the computer) and n-k zeros are supplied, c bits at a time, on inputs I 1 -I c  (top left), being connected into an n-bit buffer 26 via connector 27, and various combinations of the stages of an (n-k)-bit shift register FSR in parallel being EXCL-ORed at 15, 20, 21 with respective combinations of the current group of c bits the results being loaded into the register FSR. Finally, the (n-k) bits in the register FSR are gated in parallel via gates 28 into buffer 26 to form an n-bit word with the k data bits, this word being sent to the peripheral via lines 8a. For decoding, the n-bit word from the peripheral is placed in buffer 26 and supplied, c bits at a time, via gates 22a and lines 22, to units 20, 15, FSR, 21 with EXCLORing and feedback as during encoding. A zero result indicates no error. A non-zero result causes saving of the FSR contents in a backup register (not shown) for subsequent correction of burst errors by table look-up, programmed system diagnostics or retry (all not described), and also a parity test on the FSR contents. If the parity is even, an even-number-of-errors (uncorrectable) indication is given. If the parity is odd, indicating an odd number of errors, (n-k) AND gates at 30 look for respective patterns of ones and zeros in FSR. If any is found, the respective AND gate energizes a respective EXCL-OR at 59<SP>1</SP> to correct the erroneous bit as the first c of the k data bits are supplied in parallel from buffer 26 via connector 27a and gate 59a to output 7b (which feeds the computer via a buffer not shown). If none of the patterns is found at 30, FSR is shifted with feedback via 21 but without input to 20, and the AND gates at 30 look for their respective patterns in the result to correct, at 59<SP>1</SP>, a bit in the second group of c data bits from buffer 26, if one of the patterns is detected, but if not, shift occurs again, and so on. The whole k-bit word is accepted once a single error has been corrected in this way, but if the whole word is exhausted without one of the patterns having been detected at 30, a "non-correctable error" indication is given.

Abstract: 932,908. Continuous production of synthetic resin plates. MITSUBISHI RAYON KABUSHIKI KAISHA. Dec. 29, 1959, No. 44132/59. Class 87(2). A plant for continuously producing thermoplastic resin plates, e.g. of styrol or acrylic resin, using glass moulds comprises a water bath type polymerizing apparatus followed by an air bath type polymerizing apparatus and devices for automatically feeding the moulds to, conveying them through and delivering them from the polymerizing apparatus. The moulds into which the synthetic resin in monomer or semi-polymer form is poured comprise plates A1 having a gasket A2 interposed between them and sealed with clamps A3 to which a protecting and guiding cover A4 is attached. The moulds are stacked on trucks carried by a conveyer means 2 to an elevator device C which lowers them into a water bath type polymerizing apparatus B through which they are pushed by means of a device E. At the far end of the apparatus B, the trucks H are removed by an elevator device D similar to the device C after which they are pushed through an air bath type polymerizing apparatus G by a device F. The trucks then pass via an unloading device 4 and a conveyer means 3 to a chain conveyer 5 which carries them back to the conveyer means 2 via a loading device 1. The water and air bath type polymerizing apparatus are both required since the polymerization of synthetic resins such as styrol and acrylic resins comprises a stage in which much heat is generated followed by a stage in which polymerization takes place at a temperature above 100‹C. If an air bath type apparatus was used for the first stage, unevenness of the polymerization might occur due to the low thermal conductivity and thermal capacity of air, but the use of such an apparatus is advantageous for the second stage.
