As described peripheral devices, e.g. CRT 14, printer 13, CRT 15, and magnetic tape 12, are connected to respective switching circuits 79, 80 which act, via two transfer channels 77, 78, to connect a selected one or more of their associated peripherals to read and write heads associated with tracks 83, 84, 87, 88 on a magnetic drum store. Three external magnetic disc stores 71-73 are connectable via switching circuit to write heads associated with tracks 87, 88. The data stored in this way may subsequently be transferred to a peripheral via switching circuits 89, 90, see above. The system is controlled by program data initially loaded in track 46 from discs 71-73 via switch 76 by means of control circuit 70 which distributes control signals to the remainder of the system. An additional working store 91 and an associated data processor 61 are connected to the system with transfers between store 91, discs 71-73, processor 61, and the peripherals being possible. The arrangement allows concurrent transfers between different peripherals &c. and respective ones of the storage tracks to take place.

Filed: 1965-06-30
Abstract: 1,079,074. Electric digital data storage. ANELEX CORPORATION. June 30, 1965 [Oct. 8, 1964], No. 27630/65. Heading. G4C. In a data handling system, n stages of a shift register are loaded every (n+1) cycles of a clock-driven counter with' binary signals, and a further stage is loaded by a particular value bit, the contents of the shift register being supplied to bistable means which is switched by each bit of said particular value. Binary data is recorded on a magnetic disc, tape or drum by producing a flux transition for each ONE bit, every n data bits being preceded by a framing bit which is always ONE, and n being preselectable. Recording data.-Referring to Fig. 3, clock pulses from a generator 7 are counted by counter flip-flops C1F, C2F. On a count of two or three, depending on the setting of a switch S2 (which thus selects n = 1 or 2), gates responsive to the counter gate one or two data bits respectively in parallel to one or two of flip-flops SR1, SR2 and set a flip-flop SR3 to ONE for a framing bit. The contents of the flip-flops SR1, SR2, SR3 constituting a shift register are then shifted and gated by the clock pulses to a write flip-flop WF, each ONE bit switching it. Reading data.-Clock pulses are derived from the read waveform and used to gate the output of a transition detector also responsive to it. The pulses from the gated output which correspond to framing transitions are then removed, and the remaining pulses sent to the shift register. Modifications.-Other values of n mentioned are 3, 6, 12.

Title: Improvements in the production of terephthalic acid
Inventor: SPEER WALTER
IPC: C07C51/265
Filed: 1959-08-17
Abstract: Terephthalic acid is prepared by oxidising p-xylene with a gas containing molecular oxygen at elevated temperature in the presence of an oxidation catalyst and in the presence of at least 5% by weight of dimethyl terephthalate with reference to the weight of the mixture to be oxidised and at a temperature above the melting point of the diester.  The reaction is preferably carried out by passing oxygen through the mixture at 140 DEG C.-200 DEG C. using about 20%-50% of the diester which is said to act as an oxidation promoter and to bring about oxidation to terephthalic acid in one step.  The starting material may be pure p-xylene, commercial crude xylene or xylene mixed with partial oxidation products, e.g. tolualdehyde, toluic acid, terephthalaldehydic acid or esters of the acids with alkanols of 1 to 4 carbon atoms.  The catalyst may be a copper, cobalt, manganese or cerium salt of a higher aliphatic acid or hydrobromic acid and may be dissolved in the xylene.  A lower alkanol, particularly methanol, may be introduced into the oxidation zone during the oxidation in amounts of 0.5% to 5% by weight based on the mixture to be oxidised.  The oxidation may be carried out batchwise or continuously at normal or elevated pressures.  The product, which may contain some p-toluic acid may be esterified with methanol under increased pressure in a known manner. Examples are given. Specification 623,826 is referred to.
