Abstract: 1,254,425. Transformers. NATIONAL RESEARCH DEVELOPMENT CORP. 17 Feb., 1969 [17 Nov., 1967, 5 April, 1968; 4 Sept., 1968], Nos. 52447/67, 16386/68 and 41945/68. Heading H1T. [Also in Division H2] A static polyphase transformer/rectifier system for supplying substantially constant total D.C. output is designed so that the instantaneous power taken from each phase of the A.C. supply is always closely proportional to the square of the voltage of that phase. Fig. 2 shows a transformer having a core similar to the stator of an induction motor and carrying primary windings 1 graded so as to provide a constant rotating magnetic field sinusoidally distributed in space which cuts secondary windings 2 comprising a plurality of equal winding sections connected in ring formation with their junctions connected to rectifiers 3, 4. The secondary system 2 resembles the armature of a direct current generator and fits the stator without appreciable air-gap. Alternatively, both primary and secondary windings may be located in slots in the periphery of an inner element surrounded by plain ring laminations (Fig. 3, not shown). Zig-zag connections.-Figs. 4 and 5 (not shown) relate to the connections of secondary windings of a conventional three-phase transformer having specified ratios so as to produce a twelvephase output for connections to bridge rectifiers Ring-connected secondaries.-Fig. 6 shows the secondary windings having specified ratios of a three-phase transformer connected in a ring. Fig. 8 (not shown) relates to arrangements having twice an odd number of sections in the ring. This enables alternate diode pairs to be omitted together with certain secondary windings without impairing performance. Fig. 7 shows a low-voltage rectifier system using twelve transformer limbs (or twelve separate transformers) carrying twelve identical secondary windings 1 each being coupled to one primary winding 2 of each phase, the primaries being connected in rings as shown and graded according to the invention. Single- and two-phase operation.-Fig. 9 (not shown) relates to a ring formed by alternate connections of secondary windings from a single phase transformer, the primaries being Scottconnected and fed from a three-phase supply. Fig. 11 (not shown) relates to an LC phase shifter for operating a two-phase system from a single phase supply. Modifications.-A pulse-spreading inductor (Fig. 10, not shown) may be included in the connection to each diode pair and may be adjustable to vary the output voltage. Alternately, a coarse adjustment of output may be achieved by tap changing on the primary side whilst phase-controlled thyristors provide fine adjustment.

Title: Self advancing roof supports in inclined mineral seams
Inventor: KIBBLE JOHN DUNBAR
IPC: E21D23/04
Filed: 1964-10-16
Abstract: 1,117,312. Advancing mine roof supports. COAL INDUSTRY (PATENTS) Ltd. Oct. 18, 1965 [Oct. 16, 1964], No.42335/64. Heading F1P. When a mine roof support 2 deviates from a predetermined direction due to sliding &c. during advance by a hydraulic jack 4, the deviation is detected and a jack 6 is caused to operate so as to restore the alignment of the support in response to the deviation detected. In the embodiment shown a mine roof support 2 standing on a sloping floor is advanceable up to a conveyer 1 by contracting the jack 4 and if the support deviates from a position perpendicular to the conveyer 1 the deviation is detected by a device 5 which causes operation of the jack 6 to restore the support to the perpendicular position. The jack 6 has one end connected to the support 2 and the other end connected to a lever 7 pivoted at one end to the support 2 and provided at the other end with a roller 8 which reacts against an adjacent support 3. The device 5, Fig.2, controls the rate at which fluid leaks from a flexible line 14 and thus creates a pressure therein dependent on the deviation of the support from the perpendicular position. The fluid in the line 14 is supplied from a pressure line P through a support advance control valve 9 and a restrictor 13. Pressure in the line 14 influences a pilot operated control valve 10 loaded by pressure fluid bled through a line 16 from the line P to either connect the jack 6 to the pressure line P, to a return line R or to isolate same. In a second embodiment the support may alternatively, or additionally, be caused to align with a vertical plane or a plane perpendicular to the roof, the deviation being detected by a pendulum operated device.

Abstract: 1,023,301. Fuel ignition systems. R. T. LOVELL. March 7, 1962 [Dec. 9, 1960], No. 42539/60. Heading FIB. The outputs of individual pumps feeding the injectors 10 of a multicylinder engine are maintained equal by pressure responsive devices 30 associated with each injector. Each injector has a feed back pipe 18 through which an amount of fuel proportional to the amount injected is fed back through a pressure reducing valve 19, pipe 47 and a common control valve 31 to the fuel tank. Each feed back pipe is connected to a pressure responsive device 30 and the device 30 of the master cylinder controls the common control valve 31 whilst those of the slave cylinders operate the control rods 50 of the fuel injection pumps of the slave cylinder, the control rod 50a of the master cylinder being manually operated. The pressure reducing devices 19 comprise float chambers 20, Fig. 7, into which the feedback fuel flows from pipe 18 under the control of the float operated needle 24, the leak back fuel flowing from the chamber 20 through pipe 47 to the control valve 31 which comprises an angularly adjustable plate 44, 35, Fig. 5 (not shown) with orifices 49 co-operating with wedge-shaped ports 48 in a stationary plate 46 to which the pipes 47 are connected. Adjustment of the plate 44 varies the flow cross-section of ports 48 and hence varies the flow through pipes 47. For any given pump output the pressure responsive device 30 of the master cylinder adjusts valve 31 in accordance with the rate of flow through the associated device 19, which is a measure of the amount injected into the master cylinder. This adjustment also adjusts the flow through the pipes 47 of the slave cylinders, the pressure responsive devices 30 of which react to vary the outputs of the pumps of the slave cylinders to keep the feed back flow through all the units 19 equal to that of the master cylinder, which results in all the pump outputs being the same. The pressure responsive units 30 may comprise spring-loaded pistons or spring-loaded bellows units 32. The feed back pipes 18 are connected to feed back passages 17, Fig. 3, in the injector needle valves, which passages are connected to the injector space 15 through calibrated orifices 12 through which about 10% of the amount injected is fed back.

[Also in Group XXXVIII] A repertory keyboard-dialling magnetic drum recorder has a lid 21, latchable over the keys 34 and connected to record/playback switching such that pulses, corresponding to numbers to be dialled are recorded on adjacent one-turn tracks on a drum 30 when the appropriate keys are successively depressed, and recorded tracks, selected by a hand control 28 in conjunction with a list 26a, are played back to call a subscriber when the keys are covered and a " DIAL " bar 32 is depressed. An "OUT" key 36 enables a number to be dialled out and recorded simultaneously. A wiper 196, which makes one revolution over a printed circuit board 192 for each key depressed, the rotation being initiated thereby, initiates a 10 r.p.s. dialling switch as each of the segments 181a to 191a, up to and including the one corresponding to the key depressed is reached by the wiper 196; this switch, for 40 ms. in each revolution, cuts off an erase signal fed to the recording head 31 at intermediate times, thus allowing the recording of trains of 40 ms. " pulses " on successive segments of the record track. A rack 80, locating the head, is associated with a bail 81 carrying a pin 89 engaging a drumlocking disc 90 which prevents drum-rotation when the head is "off-track"; once the drum has started, the edge of the disc engages the pin 89 to lock the rack so that the head cannot be displaced. Each key, when pressed fully, rises part-way to engage latching means which hold it until the wiper 196 has completed its revolution and which prevent the depression of other keys until the pressed key is released. Muting means, associated with the telephone receiver-rest, prevent spurious output pulses due to moving the head 31 transversely across the tracks, during selection from being transmitted and also prevent the wanted pulses appearing at the receiver during dialling.
