Title: Remote Control of Mining Machines
Inventor: PIDGEON BRIAN GEORGE
IPC: E21C35/24
Filed: 1966-01-11
Abstract: 1,163,261. Radio signalling; inductive control of apparatus. COAL INDUSTRY (PATENTS) Ltd. 6 Jan., 1967 [11 Jan., 1966], No. 1268/66. Headings H4L and H4U. [Also in Division E1] In a control system for a longwall mining machine 10, Fig. 1, which is haulable along a face conveyer 11 into various sections A, B, C control tones (e.g. from 2À4 to 4À7 kc/s.) modulating higher frequency carriers (e.g. of 480 kc/s.) are transmitted from portable controlling stations which are capacitively or inductively coupled with an insulated conductor 17 extending from a receiver. The transmission from each portable station has a distinctive characteristic and switch means responsive to the position of the machine control the receiver to be responsive only to signals from the particular portable station associated with the section in which the machine is located. As described, portable stations 12a, 12b, 12c are associated respectively with the sections A, B, C. Each station transmits on its own carrier frequency and comprises a low frequency oscillator with a push-button operated tone selector, a high frequency oscillator, and an aerial. The insulated conductor 17 terminates on an amplifier 18, the output from which is passed through a station selector 19 to a machine controller 20. A magnet 21 is fixed on the machine 10 and two bi-stable magnetic proximity switches SS1, SS2 which are operable by the said magnet, are mounted upon the conveyer 11 at the junctions of the contiguous sections A, B and B, C respectively, and are connected to the selector 19. When the machine is in section A, the switches SS1 and SS2 are in the positions shown in Fig. 2 and a relay R1 in the station selector 19 is operated by a power supply P so that its contacts R 1 C 1  and R 1 C 2  switch in a circuit TC 1  which is tuned to the carrier frequency of the station 12a. When the machine is in section B, the switch SS1 changes over, and when the machine is in section C, the switch SS2 also changes over, so that a tuned circuit TC 2  or TC 3  (for transmissions from the station 12b or 12c) is switched in by a relay R 2  or R 3 , instead of the tuned circuit TC 1 . Time delays may be introduced in the system to prevent interruption of a master signal when the machine moves from one section to another. In a modification, the portable stations use a common carrier frequency and their transmissions are distinguished by pulse codings, individually allocated. In another modification, the magnetic proximity switches are replaced by means responsive to a machine position transducer, for example, a sensing head which counts the number of teeth passing by on a haulage gear sprocket.

[Also in Group XVIII] A consumable anode 15, for the cathodic protection of an electric immersion heater, is swaged over a sheath 16 which encloses a heating element 13 and is made of a more noble metal than the sheath 16 and its associated parts, which would be also subject to corrosion. The heater comprises a hexagonal member 10 which has a screw-threaded spigot 11 for attachment to a tank, not shown, and carries the heating element 13 with its sheaths 15, 16 and a housing 14 for a thermostat which does not support a cathodic protection sheath. The sheath 15, made, e.g. of aluminium, is applied over the sheath 16 before the element is bent to the form shown. The whole surface of the sheath 16 may not be covered by the sheath 15 in which case adjacent ends of the latter are sealed to the sheath 16. In a modification the sheath 16 of the heating element is left completely exposed, the protective sheath 15, in this case carried by the thermostat housing 14, being electrically bonded to the member 10 and the sheath 16. The mass of the protective sheath is made sufficiently large to last for the lifetime of the heater; smaller, replaceable, electrodes, however, may be fitted.

[Also in Group XL (c)] Non-homogeneous zones in an electrically non-conductive sheet of material 7, e.g. glass, are detected by directing a beam of electromagnetic waves having a wavelength greater than that of visible light on to the sheet and examining the waves reflected by or transmitted through the sheet. The preferred range of wavelengths is 1 mm. to 10 mm. and such waves may be generated by a klystron generator 1. In the reflection type system, Fig. 1, the generator 1 and a detector 2 are coupled by a magic-T waveguide junction 4 to a common transmitting and receiving transducer 3 and the relationship between the reflected signal and the direct signal from the generator 1 as determined by a detector 2 is displayed on a cathoderay oscilloscope 5 and/or recorder 6, any change in such relationship being indicative of the presence of defects in the sheet 7. The transducer 3 may be arranged to scan the sheet and one component of this scan may be provided by movement of the sheet; in such cases the beat frequency between the transmitted and reflected signals may be detected. In the transmission type system, Fig. 2, the sheet 7 under test is interposed in a gap in a waveguide 9, 10 coupled to the generator 1, the far end of the waveguide being closed by a reflecting plate 13 so that standing waves are set up in the guide, any change in which as determined by a measuring device 11 indicates a defect in the sheet 7. An array of waveguides 9, 10 may be used to scan the sheet 7.
