Title: Method of producing explosive mixture for explosion engines and carburetting apparatus therefor
IPC: F02M23/08
Filed: 1920-03-15
Abstract: 140,424. Aliverti, L. March 15, 1920. Spray carburettors.-The mixture, which is produced in the first stage by opposed currents of air and fuel, becomes weaker as the suction increases and is, in a second stage, diluted in the suction pipe with the necessary quantity of air. The float chamber 1 contains an annular float 2 which surrounds a column 4 into which is screwed a tube 5 open at the top to the atmosphere. When suction occurs, fuel enters the column 4 through aperture 27 passes upwardly through tube 5 to meet a downwardly-flowing current of air, the resulting mixture passing through holes 9 and conduits 20 to the air passage 11, whence it flows to the engine past a cock 12. The air and fuel orifices in a restricted portion of the tube 5 are of equal diameter and at a distance apart equal to said diameter. The cock 12 has at one end a coaxial automatic air-inlet valve in the form of a spring-pressed ball which admits air to the interior of the cock and is in communication through a passage 16 with the float chamber below the fuel level. The passage 16 is in communication with the air through passage 16<1> and a narrow conduit between a plug 17 and the top of the column 4. The float 2 presses against the bulbous end 23 of a lever, the other end of which is secured to the centre of a spring-loaded tilting disk valve which regulates the entry of fuel. The Specification as open to inspection under Sect. 91 (3) (a) describes also a barometric device for use in aerial navigation and consisting of a small metallic flexible membrane 30 which controls the passage 31 and therefore the entry of air to the tube 5. This subject-matter does not appear in the Specification as accepted.

Filed: 1957-03-08
Abstract: 881,651. Pulse delaying circuits. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. March 7, 1958. [March 8, 1957], No. 7782/57. Class 40(6). In a circuit for producing an output pulse Fig. 2 (e) after an initial pulse (a) an inductor I is connected in series with a rectifier 2 and capacitor 3. When the switch 5 is closed current flows, Fig. 2 (c) the potential across the capacitor rising to twice the value of the source potential V (b), while the potential across the inductor 1 rises according to curve (d). The circuit 1, 3 tends to oscillate but after a time t when the current would reverse, the rectifier 2 is effective to stop oscillation of the main circuit. During the charging process, the stray capacitance existing across the inductor 1 is also charged to the potential existing across the inductor and high frequency oscillations occur when the rectifier effectively disconnects the inductor from the remainder of the circuit. The potential occurring across the rectifier (e) provides the output signal. Alternatively, the capacitor 3 may be charged and subsequently discharged through inductor 1 by the switch 6. The output across the rectifier 2 may control a transistor or valve.

Title: Gas turbine control system
IPC: F02C7/26
Filed: 1969-02-14
Abstract: 1,254,595. Controlling prime movers.  GENERAL ELECTRIC CO. Feb.14, 1969 [March 14, 1968], No.8080/69. Heading G3R. A control system for a gas turbine engine Fig.1 (not shown) has a fuel-flow servo 11 controlling the supply of fuel to the engine according to a signal V; a programmed control means 20 supplying a first fuel control signal in response to a plurality of events taking place during start-up of the engine; a plurality of closed loop control means 14, 15, 18 each responsive to a different operating condition of the engine and supplying respective fuel control signals for controlling the respective conditions; and a gating system allowing only that fuel control signal which represents the least fuel to be applied to the fuel-flow servo. Fuel is fed to the engine by an injection pump 10 controlled by a piston actuator 26 whose position is retroactively controlled in accordance with the reference signal V. The outputs of several temperature detectors in the turbine exhaust are averaged at 39 and a speed dependant function (13) Fig. I.(not shown) generated at 41. The function is compared to a set reference 43 in amplifier 30, the output of which is connected to a bus-bar 12 by diode 31. A signal whose frequency is proportional to speed is derived from a tachoalternator (17), converted to a voltage proportional to speed at 48 and compared with a set reference 51 in amplifier 33 whose output is connected to bus 12 by diode 34. A feedback potentiometer 53 sets the droop; a switch 47 may be closed to provide for isochronous control. An acceleration signal is derived from the speed signal by differentiation (capacitor 56) and compared with a set reference 59 in amplifier 58 connected to bus 12 by diode 58a. The device 20 provides a function (21) Fig.1 (not shown) representing the fuel demanded by the various stages in starting up the engine; thus operation of switches 66, 67, 68, 69 in response to firing speed being reached by the starter; flame being detected; one minute having elapsed since flame detection; and 95% speed being reached, respectively, cause various voltages to be applied to amplifier 36 and thus to bus-bar 12 by diode 37. The diodes 31, 34, 58a, 37 are arranged so that only the lowest signal is applied to the bus-bar 12. Devices 55, 70 set the minimum and maximum signals on the bus. In the event of failure of any one signal the next highest is always available to take over control. Indicators 72, 73, 74, 75 are provided to indicate which form of control is operative at the time.

Abstract: 547,836. Transformers. STANDARD TELEPHONES & CABLES, Ltd. June 27, 1941, No. 8107. Convention date, July 3, 1940. [Class 38 (ii)] [Also in Group XXXIX] In systems in which a tone is applied to the metering wire of a connection to enable a calling subscriber's line to be identified, the identifying arrangements for 10,000 lines comprise two groups of 100 transformers each. Each transformer in the first group corresponds to a particular combination of the first two digits of the line numbers and has 100 primary windings, one connected to each of the lines having that combination. The transformers of the second group are correspondingly arranged as regards the tens and units digits. Each transformer has two secondary windings. The first winding of each of the transformers with the same thousands digit is connected to a common circuit such as M1, and the second winding of each transformer with the same hundreds digit is connected to a common circuit C1, C2 &c. Similar arrangements are made in the transformers of the second group as regards the tens and units digits. It follows that when a tone is applied to a particular subscriber's line, tone currents will be induced in the four common circuits corresponding to his number. To enable the number to be registered or recorded, the thousands, hundreds, tens and units circuits are connected up in turn to ten amplifier detectors by a relay distributer, Fig. 2 (not shown). Specifications 484,568 and 484,647, [both in Group XXXIX], are referred to. Transformers.-The 100 primary windings are applied to a transformer after it has been assembled and mounted in the form of a standard 100 conductor switchboard cable. The magnetic circuit is provided with a groove to accommodate such a cable with its protective covering removed and when the cable has been laid in place the magnetic circuit is completed.

Abstract: 918,673. Blanket cylinders. VICKERS ARMSTRONG (ENGINEERS) Ltd. Feb. 28, 1961 [March 8, 1960], No. 8159/60. Class 100 (2). Top and under blankets 12 and 11 are secured around an impression cylinder 10 by tensioning rollers 23, 24 disposed within the cylinder in association with a rotatable clamping bar 15 and a longitudinal cylinder slot 13. The rollers are corrugated in order to grip the ends of the top blanket 12 whilst the ends of the under blanket 11 are gripped respectively between the surface of the bar 15 and an inner surface of the cylinder and the surface of the bar 15 and a wall of the slot 13. Inwardly protruding pins 31 disposed along the cylinder assist the clamping of the blanket ends between the bar and the cylinder whilst to prevent undesirable flexing of the rollers they are cradled in arcuate shoes 28, 29 suitably spaced longitudinally of the cylinder. The rollers are rotated from a worm-wheel 26 through meshing gears 27 whilst rotation of the bar 15 is effected between two limiting positions regulated by a stop 21 by a lever which is attached to the squared end of the bar. The bar has a longitudinal slot through which the ends of the blanket 12 are passed after the under blanket 11 has been securedly attached to the cylinder by the bar. The latter is chamfered to provide faces 17 and 18 such that the blanket end to be secured between the bar and the cylinder may be easily inserted before being gripped on rotation of the bar. If the cylinder is intended for unidirectional rotation only one face 17 or 18 is necessary. More than one cylinder slot 13 with associated rollers and bar may be provided, in which case each slot would accommodate the ends of blankets which are adjacent one another around the cylinder.
