Title: Igniters for gas turbine engines
Inventor: BURLAND GREGORY NEIL
IPC: H01T13/50
Filed: 1984-09-28
Abstract: The electrical igniter (40) has a cavity (47), formed by a tubular semiconductor pellet (50) which, is contacted by an electrode (52) at one end, and by the outer shell (43) of the igniter at its other end, forming the other electrode. The cavity (47) opens through an aperture (48) in the shell (43) at the operative tip (41) of the igniter. The aperture (48) is inclined away from the axis of the igniter, such that, when the electrodes (52 and 43) are energised, discharge is produced in the cavity (47) and a plasma jet (60) is projected through the aperture away from the axis of the igniter, towards the region in which it is desired to produce ignition. The aperture may be axially aligned but provided with a deflector to direct the plasma jet. The semiconductive pellet may be omitted and a high voltage used to produce the plasma jet. <IMAGE>

Inventor: MEERPOHL HANSJORG
IPC: D06F34/08
Filed: 1984-10-25
Abstract: A laundry drier is provided with control means for moisture- dependent termination of the drying operation, during which laundry being dried comes into contact at irregular intervals with two electrodes (1, 6) connected to a capacitor (7) which is constantly supplied with charging current and the charge voltage of which comprises at least one monitored threshold value. The capacitor (7) is connected in series with a constant current source (8), so that the capacitor charge, when laundry is only occasionally contacting the electrodes, does not reach the threshold voltage value before an associated value of the residual moisture content of the laundry is actually reached. <IMAGE>

Title: Apparatus for disintegrating paper and cardboard
Inventor: LUMIAINEN JORMA JUHANI
IPC: D21B1/32
Filed: 1986-11-12
Abstract: Material to be disintegrated is fed, e.g. from a paper machine, into an open-topped tub (1) from where disintegrated material is removed by means of a pump, and at least two disintegrator units, preferably revolving rotors (3), are positioned on one wall (6) of the tub (1). Hitherto the positioning of the disintegrating devices has been such that they have not provided adequate space therebetween for the pump removing the disintegrated mass, and that the rotors have been arranged in a position non-conductive to efficient utilization of the flow energy, which has resulted in high energy consumption. These drawbacks are now overcome in that straight lines drawn through the axes of the shafts of the rotors (3) intersect at least in one projection. <IMAGE>

Patent GB-888396-A (GB)
IPC: H02P23/00
Abstract: 888,396. Automatic speed control systems. PHILIPS ELECTRICAL INDUSTRIES Ltd. March 12, 1959 [March 15, 1958], No. 8602/59. Class 38 (4). Control pulses from an electric motor to be synchronized are applied at S1 to the grid of a triode 1 forming a bi-stable trigger circuit arrangement with a triode 2, a reference signal R1 being applied to the grid of a triode 11 which is coupled to a triode 12. Transformers 10 and 20 supply negative and positive current pulses, respectively, to a capacitor 27, the primary windings of the transformers being in the anode circuits of the triodes 2 and 12, respectively, and the secondary circuits being completed through a triode 28. A cathode-ray counter tube 38, comprising two deflecting electrodes and an electrode for stabilizing the beam in four positions, is controlled in accordance with the charge on the capacitor 27. During the starting operation of the motor, the frequency of the control pulses S1 is lower than that of the reference pulses R1 so that the capacitor 27 is charged positively and the electrode beam of the tube 38 is deflected to the left, corresponding to the first condition of the tube. During the intervals between a control pulse and a succeeding reference pulse, the capacitor is partially discharged, whereby the beam assumes a position corresponding to the second condition of the tube. With an increase of speed of the motor, the frequency of the control pulses increases until two control pulses appear between two successive reference pulses and the electrode beam assumes its third position. During the next reference pulse the beam resumes its second position, but no longer its first. Subsequently, the time intervals during which the beam stays in its third position depend upon the phase difference between the pulses. The current through resistor 41 increases with the position of the beam, so that the cathode-follower 42 varies accordingly and the control grid of pentode 49 gradually becomes more negative. The cathode current of this pentode then decreases whereas the cathode current of pentode 50 increases and a winding 52 is excited to exert a magnetic braking force on the motor. If, due to mechanical inertia, the motor tends to exceed the synchronization speed and two successive control pulses again appear between two successive reference pulses, the braking force tends to decrease instead of increasing. This is avoided by the electron beam assuming a fourth position, whereupon a maximum braking force is continuously exerted on the motor. The motor is not braked as long as the electron beam does not exceed its second position, so that the motor starts with maximum torque. A feed-back stabilizing network comprices capacitor 47 and resistors 43, 44, 45, and a smoothing network is constituted by resistor 46 and capacitor 48. In a modification, the counter tube is replaced by a trigger circuit comprising four triodes, Fig. 4 (not shown). In another arrangement, saw-tooth control pulses are derived from a control signal produced by the motor, Fig. 6 (not shown).
