Patent GB-991039-A (GB)
Title: Data processing apparatus
IPC: G06F5/00
Filed: 1962-12-28
Abstract: 991,039. Electric selective signalling. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 28, 1962 [Dec. 28, 1961], No. 48747/62. Heading G4H. 8-bit bytes are converted to a 6-bit bytes and vice-versa. Data from a storage unit SU is handled in 6-bit bytes (actually characters) whereas data is handled in processor DP in 8-bit bytes. The bytes to be converted are transferred successively to register 1DR from where they are gated to a conversion register CR and an output register ODR. The size of CR is critical and is defined as the sum of the lengths of the bytes to be converted less the HCF of their lengths. The larger byte must be less than twice the length of the smaller byte. In the embodiment shown the length of CR is 12 bits = (6 + 8 - 2) bits. In transferring data from SU to DP the following steps take place: in succession two 6-bit bytes are transferred through IDR to fill CR; the first 8-bit byte is taken from positions T1 to T8 of CR to ODR; a third 6-bit byte is read into CR; the second 8- bit byte is taken from positions T9 to T12 and T1 to T4 of CR, the output gating Og being such that the bits occupy positions 1 to 8 respectively of ODR; a fourth 6-bit byte is read into CR and the third 8-bit byte is read from positions T5 to T12 of CR to ODR. Transfer from DP to SU is very similar, the input gating 19 being such that the second 8-bit byte is caused to occupy positions T9 to T12 and T1 to T14 of CR. The gating is described in detail with reference to Figs. 3 to 7 (not shown).

Abstract: 1,108,108. Electric cut outs. S. & C. ELECTRIC CO. 14 Nov., 1966 [24 Jan., 1966], No. 50979/66. Heading H2G. A cartridge fuse comprises a main fuse element 51 connected in series with a plurality of auxiliary fuse elements 40 and corresponding spark gaps 73 connected between the free end of the main fuse element and intermediate junctions 67 on the auxiliary fuses. The fuses 40 are each rated below the main fuse but in combination in parallel rate above it. When the main fuse 51 blows a potential difference is applied to the spark gaps 73 and one breaks down at random as indicated at 84. The whole current then passes through the corresponding auxiliary fuse 40, the major part of the current passing through the portion 68 (which is only a small portion) and through the other auxiliary fuses. The portion 68 breaks down and the whole current passes through the remaining portion 69 blowing this also. The remaining spark gaps break down in turn successively blowing the corresponding auxiliary fuses in similar manner. As shown in Figure 1, a cartridge fuse has a main fuse 50 comprising a silver wire 51 and a strain wire 52 connecting a fixed terminal 47 to a terminal 53 on an indicator tube biased to be forced outwardly by a spring 55 on blowing of the fuse. Spring contacts 58 connect between the indicator tube (and thus the terminal 53) and a fixed terminal 14 for external connection. The auxiliary fuse elements are nickel or silver alloy tapes 40 perforated as a 41 to facilitate break down, wound on an insulating ceramic former 38 and connected in parallel between the terminal 47 and a terminal 25. Metal contacts 66 engage the tapes 40 as indicated at 67 to form the intermediate junctions and have portions which project into openings 71 in an insulating flange 63 and co-operate with a conductive flange 20 to form the spark gaps. The fuse tube 65 is of fibre or inorganic material carrying a material which evolves an extinguishing gas when heated by blowing of the fuse.
