Abstract: 1,109,106. Line conductor system. INTERNATIONAL STANDARD ELECTRIC CORPORATION. 15 Oct., 1965 [21 Oct., 1964], No. 43812/65. Heading B7N. A line conductor system for an automatic train control arrangement comprises a pair of conductors 1, 2 extending parallel to the track on opposite sides a, b thereof and connected respectively to an output terminal of a pair of A.C. generators G1, G2 operating at frequencies f1, f2 and a conductor 3 connected in common to the other output terminals of the generators and disposed alternately on one side of the track in close proximity to conductor 1 and on the opposite side in close proximity to conductor 2. The cross-over points define the ends of each working section and the movement of a train over these points is detected by the change in frequency in the signal picked up from the conductors by a train carried receiving coil and transmitted to a central station. In further arrangements (a) Fig. 2 (not shown), conductors 1 and 2 cross over every two crossover sections and conductor 3 alternates at points intermediate the crossovers of conductors 1 and 2, (b) Figs. 3 and 4 (not shown), indicate arrangements whereby the pick-up coil receives either both frequencies or no signal at the crossover points and thus can determine the direction of movement of the train, and Fig. 6 (not shown) indicates an arrangement using three generators, two frequencies being picked up in each section whereby the direction of movement and also the speed of the train can be easily determined. Communication between the train and other trains or a central station may be by means of a signal at a frequency f4 via the line conductors.

Patent GB-1409653-A (GB)
Title: Methods and apparatus for inspecting the surface of sheet material
IPC: G01N21/892
Filed: 1971-09-23
Abstract: 1409653 Fault detecting in paper webs MASSON SCOTT THRISSELL ENG Ltd 19 Sept 1972 [23 Sept 1971] 44367/71 Heading G1A In a device able to investigate different kinds of faults e.g. creases, joins, stains and specks in moving sheet material comprising an optical scanner and an associated detector, the detector's output signal is fed via a selector to one or more of a number of analyzing circuits depending upon which kind of fault in the sheet material is of interest. A laser source, Fig. 1 (not shown), is directed on to a rotating prism thereby causing a beam to scan a sheet moving beneath the prism and a photo-cell 10 receives light reflecting off or passing through the sheet. Adjacent the sheet is a further detector 13, which senses the beginning of each scan. In Fig. 2, the output signal from the detector 10 is amplified and fed to a bus bar 12 which supplies the inputs to a number of analyzing circuits 20, 50, 70 along with bus bar 15 supplied from the further detector 13 connected to a monostable multi-vibrator 14 whose pulse duration substantially matches the scan duration of the sheet. Speck detection. Circuit 20 detects specks on the sheet's surface and the signal from bus-bar 12 is fed to a comparator 21 which also receives a signal from a multiple threshold selector 23 so that the comparator thereby only produces an output if the signal originating from the detector 10 is above a chosen threshold. The comparator's output is fed to a gate 30 which is also connected to bus bar 15 so that there may only be an output from the gate when the sheet is being scanned. The gate charges a capacitor and the voltage at point 33 is fed to a further comparator 35 along with a voltage derived from a multi-position stepping rheostat 36 and the comparator's 35 output is fed to an electronic counter unit 40 having several output levels (or counts) 42, 43, 44, one of which is connected via a wiper to an output alarm connection 47. Crease detection. The circuit 50 for longitudinal creases is similar to above but a gate 52 also receives an input from a monostable multivibrator circuit 54 whose time constant is substantially that of the scan time cycle. Thus a capacitor 57 is progressively charged if a fault occurs at substantially the same time in the scan cycle (corresponding to a longitudinal crease). The voltage on the capacitor 57 is then processed in a similar fashion to capacitor 32 above except that an output relay switch 81 controlling an alarm circuit 66 may be employed. Transverse fault detection. The circuit 70, designed to detect transverse faults such as joins is similar to above except that an inverter 76 is included and the multi-position rheostat is set to a level which will build up across the capacitor 79 when there is a continuous input maintained for a predetermined period which corresponds to a certain sized transverse fault.

Patent GB-460209-A (GB)
Abstract: 460,209. Skips. INTERNATIONAL COMBUSTION, Ltd., and DAVIDSON, G. W. July 22, 1935, No. 20809. [Class 78 (iv)] In skip-conveying apparatus, and in particular skip winding apparatus employed in coal-mines, a baffle 10 is oscillatably mounted in the skip 2 to prevent the material during loading from falling to the bottom of the skip, and is releasably held by means which, in a displaced position of the baffle, exert no force tending to return it. The provision of the baffle reduces the risk of breakage of the material during loading. In Fig. 4, the baffle 10 is secured to a shaft 18 having at each end an arm 30 with a roller 31 adapted to coact with a guide rail 32 pivoted at 33 and situated at the loading position, e.g. the bottom of a mine shaft. The rails 32 are normally in the full-line position shown, and as the skip approaches the loading position, the rollers 31 and arms 30 are moved outwardly by engagement therewith to raise the baffle 10 into obstructing position. A motor 36 driving a crank disc 35 connected by a link 34 with each rail 32, is then started, and withdraws the rails 32 permitting the baffle 10 to fall as loading proceeds. The motor 36 is switched on again to return the rails 32 after the skip has moved away from the loading position. The motor is controlled by a suitable arrangement of contactors actuated by movement of the skip. In Fig. 5, at each end of the shaft 18 is a brake drum 42 engaged by brake shoes 41 connected by links 40 with loose arms 37 adapted to ride over fixed guides 39 at the loading position to raise the baffle 10 into obstructing position. Slip occurs between the friction clutch elements 41 and 42 when a predetermined load has accumulated on the baffle 10 which consequently descends to release the material to the bottom of the skip. Alternatively, a dashpot or oil cataract may be employed to control the baffle. The walls of the skip may be lined with cushioning material such as rubber.

Title: Fluorescent x-ray sulphur analyser
IPC: G01N23/223
Filed: 1975-11-10
Abstract: 1533268 X-ray analysis of sulphur in hydrocarbons MITSUBISHI DENKI KK 10 Nov 1975 [22 Nov 1974] 46439/75 Heading G1A In a fluorescent x-ray sulphur analyzer the measurement of the amount of sulphur in a hydrocarbon sample is made independent of the carbonhydrogen ratio of the sample by compensating the measurement with the Compton scattering ability of the sample. In Fig. 2 an x-ray or γ-ray source 2 irradiates the sample 3, and a detector 1 receives the resulting fluorescent x-rays and scattered x or γ-rays. The detector pulses are amplified at 4 and pass along channels 5a, 6a and 5b, 6b; in the first channel a pulse height analyzer and rate meter measure the fluorescence produced by sulphur, while in the second the Compton scattered rays are measured to determine the carbon-hydrogen ratio. This produces two signals X and Y which are combined at 7 to give the fraction of sulphur in the sample. The equation combining X and Y is derived in the Specification, and a block diagram of the necessary circuitry is given, Fig. 5 (not shown).
