Patent GB-1126622-A (GB)
Title: Monitor cables suitable for use in monitoring overheating in power cables
Inventor: MASON JOHN HAROLD
IPC: H02H7/22
Filed: 1964-09-16
Abstract: 1,126,622. Monitor cable for detecting overheating. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 16 Sept., 1965 [16 Sept., 1964; 20 April, 1965; 21 July, 1965], Nos. 37852/64, 16563/65-and 31120/65. Heading H1A. The insulation 3 which separates conductors 1 and 2 is so chosen as to have a permittivity which at a given A.C. frequency increases significantly when its temperature rises above a certain value, so that a voltage across it which was not enough to induce a discharge in gasfilled cavities 5 at lower temperatures is able to start one. Voltage pulses due to the repetitive discharge are detected and their place of origin found by suitable circuits (Figs. 4 and 5, not shown), so showing the existence and position of temperatures above a certain level. The cable may be laid along the course of or incorporated within the sheathing of an underground power cable and be used additionally for communications purposes. The cable may have longitudinal holes 5 in the insulation, or the insulation may be applied over a helicallywound thread of insulating material, in such a way as not to fill the gap between turns of the thread. The holes may be made by applying the insulation in two stages, with the layer near the inner conductor having a slit in it, or a longitudinal slot, possibly discontinuous, may be machined in the first layer of insulation. Alternatively the insulation may be extruded on to the inner conductor through a shaped die, with or without the addition of a further unshaped layer. Yet again a fine tube of insulating material may be applied helically to the inner conductor and covered with insulation so that its bore constitutes a cavity. The insulation need not be continuous along the cable, but may be, for example, in the form of apertured discs (Fig. 3, not shown). Plasticized polyvinyl chloride, certain steatite mixes and dry nylon are mentioned as being suitable insulating materials.

Title: Improvements in and relating to optical instruments
Inventor: STANLEY ROY FRANCIS
IPC: G01N21/41
Filed: 1957-12-19
Abstract: 907,110. Photo - electric refractometers. BELLINGHAM & STANLEY Ltd. March 11, 1959 [Dec. 19, 1957], No. 39536/57. Class 40 (3). A refractometer comprises a prism formed of, or containing, the medium under test, pick-up means for receiving a beam of radiation passed through the prism, and means for adjusting a component in the instrument in order to measure deviation, or change in deviation, of the beam in passing through the prism. In one embodiment, radiation from a slit 3 is converted to a parallel beam and passes via prism 6, mirrors 5, 7, 9 and monochromatic filter 8 to prism 11. The prism 11 splits the beam into two, each half radiating a photo-cell 12 or 13, and when the split beams are equal the cell outputs are arranged to be balanced. Change in refractive index at the prism 6 causes the beam to be split unequally and the photo-cell outputs to be unbalanced. The amount of adjustment of mirror 7, or of the position of prism 11, to restore the balance is a measure of this change. In the circuitry for an instrument as above, Fig. 3 (not shown), the photo-cell outputs are amplified and fed in opposition to a relay which is operated when the outputs are unequal. Dependent upon which of the photocell outputs is the larger, a supply is connected via the relay to a reversible motor 22 which drives to adjust the mirror 7 or the prism 11. The motor drives a lead screw which moves a pivoted link to adjust mirror 7 and to operate a micro-transmitter which passes power to an indicator. The instrument may be used for solid or fluid media and may monitor a fluid passing through prism 6. In this case the instrument output may operate warning, plant shut-down, or plant adjustment systems. For greater accuracy in measurement a meter is substituted for the relay in the circuit described above and the lead screw is rotated by hand. A multi-turn potentiometer may be used in a modified automatic balancing circuit, Fig. 5 (not shown), the position of the wiper being proportional to the refractive index. One photo-cell only may be used and in such an apparatus means is provided for directing the two split beams on to the cell alternately and for applying the photo-cell output to the circuitry.

Alternatively, a spring may return the source to its safety position. The control system is preferably coupled to photo-electric cells 14a, 14b which allow the source to be positioned adjacent the passage 4 only when the object 15 being irradiated is present.
