Title: Graphic communication interface electrical system
IPC: H04L69/14
Filed: 1968-05-20
Abstract: 1,219,464. Facsimile transmission systems. XEROX CORP. 20 May, 1968 [25 May, 1967], No. 23959/68. Heading H4P. [Also in Division G4] A facsimile system communicates in both directions with a programme-controlled datahandling system, via an electrical adapter providing format conversions. As described, the facsimile system has a scanner using a C.R.T., and a printer using a C.R.T. and xerographic drum, and both communicate with a conventional selector channel of a System 360 computer via an adapter which controls the scanner and printer and provides serial-to-parallel conversion in computer input from the scanner and parallel-to-serial conversion in computer output to the printer. During input the scanner synchronizes the adapter with a sync. burst once per line and during output the adapter synchronizes the printer with a sync. burst per line. The adapter includes a sync. detector which during input and during a sync. window defined by a time base counter, counts clock pulses during each sync. pulse from the scanner to determine if the sync. pulse is genuine (by its duration), detects genuine sync. bursts by counting consecutive genuine sync. pulses so determined to see if the required number are present, and counts genuine sync. bursts so detected to see if the required number are present, but the latter count will be reset if a predetermined number of consecutive absences are counted by another counter. The counts are performed by different counters during sync. window and coincidence pulses defined by the time base counter. If the required number of genuine sync. bursts are detected, an "in sync." signal is generated. "Burst detected" signals produced as above are compared in phase with sweep clock signals from the time base counter (imitating the C.B.T. sweep clock in the scanner) and in dependence on the difference and the "in sync." signal, a compensation network adjusts the frequency of an oscillator. During input, this oscillator supplies clock pulses at one of two transmission line speeds, further adjusted by the compensation network above, to the time base counter which controls the adapter. During output, a crystal clock feeds the time base counter instead, and also causes generation of the sync. bursts to be fed to the printer. In both input and output, the clock pulses entering the time base counter are fed through either of two frequency dividers. Other frequency dividers are provided in connection with the crystal clock. Video pulses sent to the printer during write are stretched.

Title: Improvements in or relating to agricultural mowing machines
IPC: A01D34/30
Filed: 1920-08-18
Abstract: 150,285. Jeand' Heur, E. Aug. 18, 1919, [Convention date]. Mowing- machines.- The cutter of a mowing-machine is made of thin material and is reciprocated by being pulled from opposite ends alternately by means actuated by a cam-groove in the driving-wheel. The axle e of the driving-wheel b is secured in the forkshaped frame a by means of nuts d, E, and carries a supporting and balancing wheel g at its outer end. The nut d forms a foot-rest. A tube i is movably mounted in the forwardly projecting part h of the frame, and within the tube i is a spindle adapted to be rocked by engagement of an arm with a sinusoidal groove e formed between similarly shaped ribs on the driving-wheel b. Another arm on the spindle engages and reciprocates a slide block u mounted in a casing j, which is attached to the tube i and carries a finger-bar m. The thin cutter t is hooked to the block u and to the outer end of a bar q, which slides under guide-lugs o, p and is provided with a screw s bearing on the block u, for putting tension on the cutter. A track-clearing plate x is bolted to the part p on the finger-bar m. The height of cutting is regulated by means of the plate x and an adjustable shoe a<1>. The driver's seat is mounted on a spring support extending back centrally over the main wheel b, so that the driver's weight tends to balance the weight of the frame and the reaction of the driving-wheel on the driving-arm. The draught shafts are carried by a pivoted socket member d<1> which supports a swingle-tree m. One of the shafts is readily removable so as to allow of the cutting-apparatus being turned into a vertical position for transport, after having been pushed forward to throw the driving-mechanism nut of action. This forward movement is effected by means of a lever engaging with the tube i. The cutting-apparatus may be raised for passing over obstacles by turning the frame a about the axle e by means of a lever connected to the socket member d', a spring catch being provided to support the frame in its raised position for transport.

Title: Improvements in and relating to electric switches
IPC: H01H19/58
Filed: 1932-08-29
Abstract: 386,917. Snap-action switches. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Kempton, L. A.; R.F.D., No. 4, Bridgeport, Connecticut, U.S.A.) Aug. 29, 1932, No. 24095. Convention date, Aug. 28, 1931. [Class 38 (v).] Electric switches comprise stationary contacts 2, 3, 4, 90‹ apart mounted on a base and engaged by a polepiece 10 on rotary member 8 and a pair of stationary contacts 5, 6 arranged one above the other and insulated from each other except in one position by a disc 13 mounted on the rotary member. The contacts 2, 3, 4 are in the same plane and are adapted to be engaged by three radial arms 11 on the polepiece which moves with a snap action. The switch is adapted to control heating units 18, 19 connected together at one end. The electric supply source is permanently connected to one end of the unit 19 by a conductor 20, the other conductor 21 from the supply source is connected to the contact 4. The position shown in Fig. 4 is the off-position. When turned through 90‹ clockwise the conductor 21 is connected through the polepiece 10, contact 2, and conductor 22 to the common ends of the heating units, the aperture in the disc 13 allows contacts 5, 6 to engage to connect the other ends of both units to the conductor 20 and thus the units are connected in parallel. This is the highheat position of the switch. Turned through a further angle of 90‹, the polepiece 10 connects contact 3 also to conductor 21 and thus cuts out unit 18 and the disc 13 again separates contacts 5, 6. The unit 19 alone is in action, to give the half-heat position. Turned through a further angle of 90‹ the contact 3 alone is connected to the contact 4 and the units are connected in series to give the low-heat position. The contacts 5, 6 may be electrically connected by a metal piece bent around the disc 13 and secured by bent projections.

Patent GB-208208-A (GB)
Title: Improvements appertaining to picking or shuttle actuating mechanism of looms
IPC: D03D43/00
Filed: 1922-09-11
Abstract: 208,208. Hodgson, Ltd., G., Elsworth, J., and Bailey, F. Sept. 11, 1922. Picking-motions.-A picking-motion is put into action only when an empty cell is indicated in the opposite shuttle box, and is sustained in action, for a sufficient period for the shuttle to be picked, by curved levers actuated from the laysword. After the shuttle has been picked, the indicating mechanism in the shuttle box is disengaged from the picking control mechanism so that the shuttle may actuate the swell lever in the usual way. Fig. 1 is an end elevation and Fig. 2 is a sectional front elevation of one side of the loom while Fig. 3 is a front view of both sides which are identical, the parts on one side being distinguished from the other by adding the suffix a. In operation, the recoil of spring 40a rocks the shaft 4<a> and so presses the lever 3<a> against the swell lever 2a in the shuttle box cell, in which, if empty, the lever travels to its full limit. When the shaft 4<a> is rocked, motion is transmitted through a'link system 5, 6, 7, 8, which raises a bunter lever 9 on the laysword G to engage with a lever 12 connected by parts 13, 14, 15 to a clutch 16 which couples the picking shaft 17 to a driven part when the laysword G swings back. The lever 12 is pivoted at 12<c> and has a runner 20 at one end which runs over the curved part 21 of the lever 13 which is thereby held stationary for a period and thereby holds the clutch in for a time long enough for the shuttle to be picked. To free the swell lever after indicating, a supplementary lever 90 fixed to the rod 8 lifts the lever 9 to engage with the notch k in the lever 12, and when once engaged the lever 90 is free to be forced down out of position. To suspend the picking operation to make adjustments, e.g. "lagging-back," a rod 54 coupled to hand-operated means engages a lever system 53 which, by pulling down a rod 51 coupled to the lever 90, allows the lever 9 to remain down out of engagement. The lever 9 may be adjusted by a screw 10.

Patent GB-364136-A (GB)
Title: Improvements in thermionic cathodes of vacuum electric tube devices
IPC: H01J9/08
Filed: 1930-08-18
Abstract: 364,136. Thermionic cathodes. ROBINSON, E. Y., Garvary, Dryden Road, Bush Hill Park, BARTON, F., 41, Glebe Avenue, both in Enfield, Middlesex, and ASSOCIATED ELECTRICAL INDUSTRIES, Ltd., Crown House, Aldwych, London. Aug. 18, 1930, No. 24707. [Class 39 (i).] The heater of an indirectly heated cathode is provided with an insulating refractory coating by coating it with a substance which is converted by heat or chemical means into the insulating refractory material. In one method the wire is passed through a bath of fused aluminium nitrate and the coated wire heated to convert the nitrate into oxide. A suspension of aluminium nitrate in a saturated solution of aluminium nitrate may be used as the initial coating material. The suspension may be made by ball milling aluminium nitrate and water for several days. A suspension of aluminium nitrate in glycerine may also be used, and agglomerants such as starch, dextrin, gum tragacanth or gum arabic may be added to the suspensions. In another method the wire is dipped in a saturated solution of aluminium nitrate and subsequently heated. In order to increase the amount of material picked up by the wire on immersion the wire may be wound with cotton which is converted by nitric acid into cellulose nitrate. The aluminium nitrate picked up by the wire and its coating may be converted into ozide by heating or by treatment with ammonia which converts it into the hydroxide. It is then passed through acetone vapour or the vapour of a nitrocellulose solvent which coagulates or gelatinizes the cellulose nitrate covering, and the wire is finally heated to ignite the covering and leave a coating of aluminium oxide. Instead of compounds of aluminium, compounds of magnesium or zirconium may be used such as the nitrates or chlorides. In the latter case the coated wire is heated in ammonia to produce the hydroxide. .Specification 278,787, [Class 39 (i), Electric lamps, Arc &c.], is referred to. Reference has been directed by the Comptroller to Specifications 306,832, 308,217, and 310,829, [all in Class 39 (i), Electric lamps, Arc &c.].

Title: Improvements in or relating to fuel control systems for two-spool gas turbines
IPC: F02C9/16
Filed: 1953-09-08
Abstract: 757,341. Automatic control systems for gas turbines. UNITED AIRCRAFT CORPORATION. Sept. 8, 1953 [Dec. 6, 1952], No. 24806/53. Class 38 (4). In Fig. 1 a split jet turbine 10 comprises high and low pressure sections having coaxial shafts driving high and low pressure compressors respectively. A voltage dependent on the speed of the high pressure turbine, derived from a tachometer alternator 12, is compared with a voltage corresponding to a desired speed derived from a manually set potentiometer 48 and a speed error direct voltage thus derived from a bridge circuit 14 is applied to a cross-over network 18. A voltage dependent on jet tailpipe temperature derived from thermocouples 20 is applied to another cross-over network 22 from which a temperature error direct voltage is applied through an amplifier 24 to cross-over network 18. The two inputs to cross-over network 18 are arranged to be positive for overspeed and over-temperature and negative for under-speed and under-temperature. Crossover network 18 includes biased rectifiers so arranged that speed or temperature error voltage, according to which is the most positive or least negative, is passed to an amplifier 28 to control the energization of a solenoid. 30 operating a control valve 32 regulating the supply of fuel from a pump 38 to fuel jets 36. A voltage, the frequency of which is dependent on the speed of the low-pressure turbine, derived from a tachometer alternator 220, is applied to cross-over network 22 in which a corresponding direct voltage derived from a frequency discriminator circuit over-rides the thermocouple voltage, if the speed of the lowpressure turbine is excessive, e.g. due to afterburner flameout, so that the fuel supply is controlled in accordance with low pressure turbine speed. Amplifiers 24, 28 are of the type which have their inputs and outputs chopped by switches, e.g. 74, 80, operating synchronously. The temperature datum of the system may be adjusted by varying the potential of contact 79 of switch 74. Power unit 54 for the system derives its power from an external A.C. supply 60 during engine starting but changes over to alternator 12 when a relay 64 is energized automatically at a piedetermined speed.

Patent GB-1603169-A (GB)
Title: Electrically welding plastic sleeve
IPC: H02G15/10
Filed: 1978-05-31
Abstract: The disclosed sleeve is of the type including a resistance heating wire embedded in a thermoplastic sleeve material. A first sleeve member of insulating thermoplastic is molded with axially spaced integral annular receptacle wall members extending out from the outer surface and defining recesses. The walls have two diametrically opposite guide slots. Extending upwards from the center of each recess is a wire support stud. A resistance wire wound on the first sleeve between the wall members has its end sections passed through the slots and over the support stud, so that portions of the wire lie exposed against the side faces of the stud. A second sleeve member of insulating material is molded over the first sleeve so that the wire is embedded in the second sleeve but remains exposed within the recesses. The second sleeve material fills in the slots above the wire to thereby fix the wire in place in the slots. This permits a mating connector element to be inserted in the recess with its bore receiving the wire and wire support, so that electrical contact is made to the wire.
