Title: Method and apparatus for producing plastic insulated electrical conductors
Inventor: PULL ERNEST HAROLD
IPC: H01B13/00
Filed: 1963-12-10
Abstract: 1,107,253. Shaving cable insulation. SUBMARINE CABLES Ltd. 3 Dec., 1964 [10 Dec., 1963], No. 48837/63. Heading H1A. In order that the outer surface of the core of a coaxial submarine cable should be smooth, accurately cylindrical and of constant outer diameter and that the inner conductor should be centred precisely, an oversize polyethylene sheath is extruded on to the conductor and is then trimmed to the desired size by passing the insulated conductor through a guiding device, capable of accepting irregularities in diameter, through a fixed, non-rotating cutting die to remove excess insulating material, slitting the swarf to permit its removal as a continuous ribbon and supporting the shaved insulated conductor in coaxial relationship with the die after its passage therethrough. As shown the position and direction of approach of the core C to die 1 is controlled by tubular support 5 hinged at 6 and containing collets 3 and 4. Presentation of the core to the die obliquely is stated to have the advantage that the movement of a control device is much larger than the adjustment effected. After shaving, minor eccentricities of the conductor within the sheath are detected by a sensing device 9 and corrected automatically by two actuators, of which 11 is one, at right angles. The sensing device (Figs. 8 and 10, not shown) comprises four electrodes arranged on the circumference of a circle round the core and having a common guard electrode, and depends on the capacitance between these electrodes and the conductor. Eccentricity of the conductor leads to imbalance in a system consisting of two Blumheim bridges (Fig. 10, not shown) and the out of balance voltage across each pair of ratio arms is amplied and applied to the input of a pair of modulators adjusted to be responsive only to capacitive imbalance, thus producing D.C. outputs proportional to the eccentricity in each of two planes. Part of these D.C. outputs in due course drives the motors of the actuators.

Abstract: 1534523 Error correction in computer memories SPERRY RAND CORP 17 Dec 1975 [17 Dec 1974] 51624/75 Heading G4A A data processing system including a main memory system, e.g. a LSI semiconductor memory system 10 capable of storing M word groups of N bit planes per word group and B bits per bit plane, each bit plane being a replaceable component that, upon the detection of a single defective device or bit therein, indicates a correctable error upon readout, includes single error correction circuitry 12 for generating on the detection of each correctable error in memory system 10 an error word comprising a tag bit 2<SP>T</SP> and S syndrome bits, the tag bit indicating that a correctable error has occured in that one of the N bit planes which is identified by the S syndrome bits, a memory address register 14 holding W ordered bits that address a selected word group and X ordered bits that address the same bit on each bit plane in the selected word group, and a circuit 16 for logging the number of correctable errors detected in different word groups and alerting an operator that preventative maintenance is necessary when the number exceeds a predetermined value. Each error word from circuitry 12 has its tag bit and W address bits fed to a (1+W) -bit address register 30 of a word group address buffer 18 that in turn comprises (1+W) vertically disposed shift registers each Y ordered stages in length, their like-ordered stages being arranged to form Y address registers each (1+W) stages in length (Fig. 5, not shown). The corresponding syndrome bits of the error word are fed to an S-bit address register 34 of a bit plane address buffer 20 that in turn comprises S vertically disposed shift registers each Y ordered stages in length and arranged similarly to buffer 18. The contents of register 30 are compared in turn with the contents of the Y address registers of buffer 18 and if no match is found, the corresponding error word is entered into buffers 18, 20 and the contents of each address and syndrome register thereof shifted upwards one register. If, conversely, a match is found, the error word from registers 30, 34 is not entered into buffers 18, 20 and upward shifting thereof is inhibited. When the number of words in buffer 18 reaches the predetermined value, as detected by monitoring the tag bit position of a given address register, a signal is emitted on a line 86 alerting the operator that preventative maintenance is required. The contents of buffers 18, 20 may then be read out to respective displays 88, 89 to identify the location of the defective bit plane. Entering of error words into buffers 18, 20 and upward shifting thereof is also inhibited when buffer 18 becomes full by means of a signal on a line 82. It is stated that the invention enables replacement of defective bit planes before there is a significant probability of encountering a non-correctable double error within a word read from the memory system 10.
