Title: Improvements in or relating to liquid fuel apparatus for the furnaces of locomotive and other boilers
IPC: F23D99/00
Filed: 1925-01-17
Abstract: 237,166. Davis, F. J. Jan. 17, 1925. Spray burners. - In the liquid-fuel injector burner apparatus described in Specification 21837/10 for heating locomotive and other furnace boilers, an additional orifice m supplied with fuel such as paraffin under pressure is provided adjacent to the two small steam jet orifices k at the bottom of the burner for use as an auxiliary burner to heat up the boiler until the necessary steam pressure has been raised to supply the burner. The orifice m is preferably formed in a hollow plug q which is screwed against a solid plug s in a recess p arranged between the orifices k and below the converging fuel orifices e. The fuel to the auxiliary burner is supplied through a pipe n arranged in the pipe h supplying steam to the orifices k and passes through radial passages t, a peripheral groove u, and helical grooves v in the plug s to a space w communicating with the orifice m so as to issue as a whirling spray. The front of the burner is formed with a gutter x to lead any unatomized fuel issuing from the fuel orifices e towards the orifices k. Automatically-operated valves may be provided to admit steam to the burner and to cut off the fuel supply to the auxiliary burner when a predetermined pressure has been reached in the boiler.

Title: Improvements in and relating to Wireless Signalling Systems.
IPC: H04L5/06
Filed: 1918-01-30
Abstract: 128,682. British Thomson - Houston Co., (General Electric Co.). Jan. 30, 1918. Wireless signalling; multiplex wireless signalling.-In wireless signalling systems employing continuous waves, amplitude pulsations of the oscillations in the antenna are produced by a series of alternating currents of different frequencies of a lower order than the wavefrequency. In the arrangement for multiplex signalling shown in Fig. 1, the antenna 1 is' energized by a high-frequency generator 2 driven by a motor 4. On the same shaft are arranged three alternators 19, 20, 21 of differing and preferably audible frequency. A magnetic controller 8 of the kind described in Specification 7151/13 has its windings 9, 10 connected as a shunt across the secondary 7 of the energizing-transformer 3. The windings 9, 10 are also traversed by direct current from a source 13, and by alternating current from the alternators 19, 20, 21, the sources 13, 19, 20, 21 being in parallel across the terminals 14, 15 of the windings 9, 10. Adjustable resistances are placed in the various circuits, and signalling-keys 28, 29, 30 in the alternator circuits. In this way, the amplitude of the current in the antenna 1 is varied according to a sine-wave law, the frequency of the pulsations being that of the particular alternator that has its circuit completed by a signalling- key. At the receiving-station, the received oscillations, after rectification, are passed in series through three circuits turned to the respective frequencies of the alternators 19, 20, 21. The low-frequency impulses are then transferred through loose electrostatic couplings to three secondary tuned circuits, each having a telephone connected across its capacity. In a modification for preventing another station from interfering with the signalling, a single signalling-key is placed in the common circuit of the alternators, and a single telephone 56, Fig. 4, is employed at the receiving-station; which may be connected, as desired, to the three tuned receiving-circuits 37, 38, 39. Signals are thus sent out on three modulated waves, and if an interfering station prevents reception at one modulation frequency, the receiving-operator may switch the telephone 56 on to one of the remaining reeciving-circuits. Another arrangement for secret or selective working is shown in Fig. 5. A rotating commutator 60 places each alternator 19, 20, 21 in turn in circuit with each key 28, 29, 30. At the receiving-station, a synchronous commutator connects the telephones in turn to the respective receiving-circuits. Amplitude pulsations of frequency lower than the audible frequencies may be employed for giving visible signals, or ultraaudible frequencies may be used. The system may also be used for transmitting from a single station to several receiving-stations at varying distances, the magnitude of the amplitude pulsations being increased for the more distant stations by reducing the resistance in the alternator circuit. Specification 30030/09 also is referred to.

Title: Multiple speed accessory drive for motor vehicles
IPC: F16H9/04
Filed: 1959-01-19
Abstract: 910,349. Change-speed gear; clutches. BORG-WARNER CORPORATION. Jan. 19, 1959 [Jan. 27, 1958], No. 1963/59. Class 80 (2). A two-speed gear for the drive of a vehicle accessory such as a water pump, comprises a pulley 30 clutched to an input shaft 14 at low engine speeds by a centrifugally disengageable friction clutch 28 and driving a pulley 32 on an output shaft 34 at a step-up ratio, and a pulley 40 connectable by an over-running clutch 42 to the input shaft 14 when the centrifugal clutch 28 disengages at a predetermined engine speed and driving through belting 38 a pulley 36 fast on the output shaft at a reduced ratio. The over-running clutch 42 comprises axially movable parts 120, 138, the part 120 being fast with the pulley 132 and having facial ramps 136 co-operating with facial ramps formed on the. part 138. At low engine speeds the pulley 132 is rotated by way of pulleys 30, 32, 36 faster than the input shaft and the ramps on the parts 120, 138 assume a mating relation, and part 138 is rotated idly by the part 120. When the clutch 28 disengages, the speed of the pulley 132 drops and relative rotation occurs between the parts 120, 138 which are thereby cammed apart by the ramps, forcing the part 138 and the pulley 132 into engagement with friction facings 142, 144 carried by parts fast with the input shaft. The centrifugal clutch 28 comprises a drum 50 formed on the pulley 30 engageable by a friction band 66 carrying at one end a block 64 in which a roller 106 is mounted. An arm 26 is fast on the input shaft and has a centrifugally responsive lever 84 pivoted thereon about a pivot 82, a tab 91 integral with the lever 84 engaging the roller 106. The lever 84 is spring-biased anti-clockwise as viewed in Fig. 2. A retainer block 58 is provided on the arm 26, a spring ring 61 interconnecting the blocks 58, 64. When the input shaft is driven slowly the tab 91 engages the roller 106, urging the block 64 radially inwardly, and force is transmitted through the block 64, spring 61, and block 58 to a cam 76 adjustably mounted thereon. Cam 76 cooperates with a portion 70 of the friction band. The band is thus contracted on to the drum 50 and the clutch is engaged. At a predetermined engine speed the lever 84 pivots clockwise under centrifugal force and the tab 91, acting through the roller 106, spreads the spring ring 61, thus expanding the band 66 to its disengaged position. The driven parts of the centrifugal friction clutch 28 and the overrunning clutch 42 are freely mounted on porous bronze bearings 46, 122 which are rotatably mounted on the input shaft. The input shaft is hollow, and the hollow interior is packed with grease which passes to the bearings under centrifugal force through ports 168, 166 and thence to the inner peripheries of the driven members of the clutches by capillary action.

Additional windings 13 .. 16 on the transformer supply heating current to the cathodes of the rectifiers, and to the cathode of the oscillation generator. The anode 2 of the generator, being earthed, may be cooled without the necessity of insulating the apparatus supplying the cooling water. In a modification, a conductor is provided between the anode 2 and the neutral point of the transformer, and a switch is provided by means of which either the neutral point of the secondary winding or the anodes of the rectifiers may be earthed. In order to reduce ripples in the direct-current circuit, the arrangement shown in Fig. 3 may be used. In this arrangement, two three-phase secondary windings 20, 21 are employed in combination with six rectifiers, the anodes of which are all connected together. The neutral points 22, 23 of the secondary windings are connected together through an inter-phase transformer 24, to which the other side of the direct-current circuit is connected as shown.

Filed: 1958-01-23
Abstract: 832,127. Wrapping-machines. PACKAGE MACHINERY CO. Jan. 23, 1958 [March 22, 1957], No. 2282/58. Class 94(1). A device for overlapping the edge portions of a wrapper partially folded round an article being carried on a conveyer, comprises a series of transverse bars, moving at a speed greater than and in the same direction as the article, which engage the wrapper edge portions so that the leading one thereof is initially held away from the article while the trailing one is folded down on to the article. The invention is described as applied to a wrapping machine of the kind set out in Specification 770,124. The device is sited beneath the gap between spaced plates 30, 60 below the machine conveyer 20. The bars 32 are carried in spaced groups on conveyer chains 34, 36, with a single bar 32g in each gap initially between the groups. The wrapper has its leading portion x folded on to the article bottom face and its trailing portion y extending behind the article. As the article moves over the gap between plates 30, 60, it is supported by the last bar 32f of a group and the portion x springs down into the gap. A bar 32g engages the article and the portion y drops into the gap behind it. As the bar 32g advances relative to the article it folds back the portion x and the leading bar 32a of the next group lays the portion y onto the article. Finally, as the article travels over the plate 60, the latter lays the portion x on to the article and the portion y. The downward movement of the portions x, y may be assisted by air blown through ducts 90, Fig. 2 at the forward end of the plate 60 and tubes 106 above the gap. A reciprocating suction arm 70 may grip the portion x to pull it downwards. Reference has been directed by the Comptroller to Specification. 770,124.

Title: Deflection system with overscan protection
IPC: H03K4/72
Filed: 1976-01-21
Abstract: 1528872 Sawtooth deflection system RCA CORPORATION 21 Jan 1976 [10 Feb 1975] 02309/76 Heading H3T A deflection system overscan protection circuit comprises a sawtooth waveform generator 31-35, an amplifier 70 for providing a sawtooth scanning current to a deflection winding 57, 58, an arrangement 59, 69 for obtaining a parabolic voltage waveform from the winding and for superimposing the parabolic voltage on a DC supply voltage of the generator whereby a change in peak amplitude of the parabolic voltage consequent to a reduction in the operating frequency causes the generator to change its frequency for reducing the peak amplitude of the scanning current. The scan voltage developed across capacitor 35 causes during its first portion transistors 45, 46 to conduct with current flowing in one direction from a capacitor 69 via the deflection winding 57, 58 and through the transistors 45, 46, and during a second portion current to flow via transistors 43, 44 in the opposite direction through the winding 57, 58 and into the capacitor 69 thus developing a parabolic voltage across it. During the retrace portion, transistors 43-46 are cut off and energy stored is dissipated by resonant exchanges between the winding and a capacitor 50. The sawtooth generator comprises a first portion including a capacitor 29 charged via resistors 24, 15, 20 and 21, and discharged via transistors 18, 16 when a threshold voltage is reached or when transistor 18 is turned on by incoming sync pulses 11. A second portion including a capacitor 35 is charged via resistors 31, 32 and discharged via the transistor 16. The frequency of the generator when low due to maladjustment of potentiometers 20,32 or when free-running in the absence of sync pulses, can be increased by a variation in amplitude of a parabolic voltage applied at one supply terminal. The superposition of the parabolic voltage on the supply voltage effectively lowers the threshold voltage at point B by virtue of the slopes of the parabolic waveforms (Figs. 2g, 2h not shown) and hence causes the switch transistors 18, 16 to be turned on early for discharging capacitors 29, 30.

Abstract: 819,326. Apron conveyers. NOE, O. Jan. 23, 1957 [Jan. 25, 1956], No. 2468/57. Class 78 (1). In an apron conveyer having alternate pans 4 secured to a chain or chains 1 and the intermediate pans 13 adapted to bridge the gaps between downturned ends 5 of the pans 4, the intermediate pans are provided with extensions 14 on their undersides which extend under the ends 5 of the pans 4 and are pivotally connected by means of cross rods 8 within slots 7 arranged in brackets 3 on the undersides of the pans 4, the arrangement being such that relative longitudinal movement can occur between the pans 4 and 13. For this purpose, one of the extensions 14 has a slotted hole 15 for the rod 8 while the other extension has a round hole 16. The rods 8 are arranged to lie below the arcuate end portions 5 of the pans 4, the brackets 3 being secured centrally of the plates 4 within central arcuate portions 6. Some of the brackets 3 are extended laterally and provide supports for supporting rollers 9 and guide rollers 11. The pans 13 are arranged so that the two pans 13 adjacent to a roller-equipped pan 4 have their slotted holes 15 adjacent the pan 4 so that flexing of the apron in a horizontal plane occurs at these pans 4. The pans 4 are connected to one or two endless chains 1 by providing four equally spaced grooves on the undersides of the brackets 3 to take one or two horizontal links which are clamped by a complementary clamping plate 2. The pans 13 have longitudinally extending recesses 17 formed in their bases to accommodate the chain when passing around the terminal sprockets. Instead of recesses 17 the floors of pans 13 may comprise an elastic portion 18, Fig. 5, which is deflected upwardly by the chain at a terminal, and is deflected downwardly on to the chain on a straight run by the material being conveyed, giving increased handling capacity.
