Title: Improvements in the detection and localisation of faults in underground cables
IPC: G01R31/08
Filed: 1921-10-08
Abstract: 191,443. Taylor, A. M. Oct. 8, 1921. Locating faults.-In electric transmission high-tension systems employing underground cables with multi-concentric, single, or other cores and with sectionalized lengths A of lead sheathing earthed at their mid-points, faults are detected or located by connecting the ends of the lengths A at which like potentials are normally induced by pilot wires N, Fig. 2, to a common bus-bar through indicators preferably having polarized armatures, the change in potential of a pilot wire due to a fault or any length A operating the corresponding indicator. In order to limit the number of pilot wires entering the generating station or sub-station, the common bus-bar of the pilot wires N leading from the ends of the lengths A in a local length of cable is mounted in a local indicator box RB connected by a pilot wire G to the station, the actuation of any local indicator closing the circuit of a relay P in the box RB and the armature Q of the relay P closing a circuit to the station through the wire G and ringing a bell and operating an indicator at the station. In the arrangement shown in Fig. 2, the faultindicators are applied to a 3-phase system employing three separate cables, and mid-points of the lengths A being earthed directly or connected to a copper earthing conductor laid with the cable. The circuits through the pilot wires G from the local boxes RB to the station are completed through earth or return wires, the wires G being connected at the station through indicators and relays and a common battery to earth or the return conductors. The indicators at the station locate the particular local box affected and the indicators at this box locate the faulty length of sheathing. The lengths A may be connected together by junction boxes comprising two members Z, Fig. 1, having flanges separated by an insulating partition Y and bolted together by insulating bolts, the boxes also divided into two parts parallel to the length of the cable so that the parts Z can be connected together before application to the cable.

Title: Improvements in and relating to automatic reclosing circuit breaker systems
IPC: H02H3/06
Filed: 1923-10-25
Abstract: 216,783. British Thomson-Houston Co., Ltd., (General Electric Co.). Oct. 25, 1923. Cut-out systems.-In an automatically reclosing circuit-breaker system, the load resistance is so connected in relation to other fixed resistances as to constitute one arm of a Wheatstone bridge, the " galvanometer connection " being constituted by an electron discharge tube the current in which is independent of the voltage of the supply, varies directly with the load resistance and serves to operate a reclosing relay. As shown, the direct current generator 2 supplies the load R<4> through a circuit-breaker 1 which is shunted by a resistance R, R<1>. On overload, the relay 14 opens and the closing and maintaining coil 5 is de-ernergized so that the back contacts 8 are opened and the back contacts 16 closed supplying current to the time relay 17 which closes the contacts 19. This connects two resistance arms R<2>, R<3>, themselves connected together through the cathode 23 of an electron discharge device, to the supply circuit. The other two arms of the bridge are constituted by the resistance R<1> and the load resistance R<4>. The grid 26 is connected in the galvanometer connection, being connected at the junction of the resistances R<1>, R<4>. The plate 25 is connected through the coil 13 of the reclosing relay to the positive of the generator and consequently is more positive than the cathode. The resistances R', R<2>, R<3> are chosen of such value that, with a given generator voltage and the circuit-breaker open, the potential difference between the points to which the cathode and grid are connected is zero when the load resistance is such that the circuit-breaker may safely be reclosed. The relay 13 is so designed that it will operate in response to the value of current that flows through the tube when the potential difference between the points referred to is zero. In order, however, to obtain sufficient current through the tube to operate the relay in the above conditions a battery 20 is connected in series with the grid.

Abstract: 731,295. Reservoir pens. SMITH G. H. (Filler & Fiebig Ges.). Oct. 26, 1953 [Oct. 24, 1952], No. 26779/52. Class 146(3). In a pen of the kind having a small ink reservoir 1 tapering to a fine writing tube 4, and a cap 5 closing the reservoir, there is provided for cleaning the tube, a spring-raised plunger aligned with the tube and slidably mounted in a bore in the cap so as to pass through the tube and project from the end when the head 14 is pushed down. The plunger consists of a tube 12 passing through the cap and a wire 15 retained in the tube by flattening it at 16. This flattening prevents the plunger leaving the bore in the cap. A vent opening 17 in the reservoir wall is adapted to be closed when the pen is out of use by the clip 6 by means of which the pen is attached to an L-shaped bracket 8, 9 on the holder 7. When not in use the pen is turned into alignment with the holder and pushed along the slot in the arm 9 so that the writing tube is received in a recess 11 in the end of the holder. The tapered part 2 of the holder closes the recess to prevent the ink in the tube drying up. For fine writing tubes needing a fine wire 15 the arrangement is modified as shown in Fig. 2 to avoid a shoulder at the inner end of the tube.

Title: Pneumatic despatch and conveyance of articles
IPC: B65G51/02
Filed: 1969-05-27
Abstract: 1,217,116. Pneumatic conveyers. TOBACCO RESEARCH & DEVELOPMENT INSTITUTE Ltd. 27 May, 1969 [30 May, 1968; 9 Sept., 1968], No. 26804/69. Heading B8A. An arrangement for feeding rod shaped articles into a pneumatic conveying tube 26 comprises a pair of one-way valves 12 and 14 in a conveying tube section 16 between the tube 26 and a vertical column 10 of articles laterally offset from the line of the tubes 16, 26, and means for applying a suction and pressure cycle to the arrangement whereby the movement of the articles one at a time from the bottom of the column 10 into alignment with and into the tubes 16, 26, is pneumatically controlled. In operation, suction is applied at a part 20 whereupon the valve 12 is opened allowing suction to be applied to the column of articles, this causing a free swivelling locking element to move in between the lowest two articles to support the articles above the lowest one, which is then sucked into alignment with, and into the tube 16. The port 20 is then closed and pressure is applied to a port 18 whereupon the valve 12 closes, the valve 14 opens and the article passes into the conveying tube 26. Pressure supplied to a port 24 closes the valve 14 and conveys the article along tube 26 once the pressure part 18 is closed. With the closing of the valve 12, the locking element gravitates into its inoperative position and the column of articles is lowered ready for the next intake. In the embodiment of Fig. 3 (not shown), the locking element is replaced by pneumatic means comprising a port communicating with the lowermost article of the column and being supplied with pressure to move the article into alignment with the conveying tubes when the upstream valve is closed, and with suction to hold the following lowermost article out of alignment while the upstream valve is open. A further port supplies pressure alongside the column coaxially with the conveying tubes, whereby both actions of the first said port are assisted.
