Patent AT-E3130-T1 (AT)
IPC: H04N3/16
Filed: 1980-02-05
Granted: 1983-05-15
Abstract: An amplifier includes first and second switches coupled at a junction to form a series circuit. The series circuit is serially coupled with an inductor across a source of energizing potential. A capacitor couples the junction between the switches to a load. The switches conduct alternately under the control of a duty cycle modulator. The duty cycle modulation tends to vary the amplitude of the two opposite-polarity portions of the signal appearing across the load. A clamp is coupled to the junction of the series switch circuit and the inductor. The clamp operates during a first of the two alternate switch conduction intervals to clamp the voltage across the inductor at a fixed value. Since a direct voltage cannot be established across an inductor, the voltage across the inductor during the second switch conduction interval is established by the clamp voltage and the duty cycle, and varies with duty cycle. The amplitude of the signal at the junction of the two switches varies with duty cycle variations in such a manner as to maintain the signal of one polarity across the load at a constant amplitude.

Date Jan. 22, 1981.The present invention concerns a flyer for roving frames. According to the invention the flyer arms (14,16) at their free ends are connected rigidly with a ring (17). Furthermore, an enclosed guide duct with a guide tube (22) is provided for the roving, which guide tube (22) is supported to be pivotable about its longitudinal axis and supports a presser finger (25). Thus, a flyer of relatively low weight results, but of high solidity, permitting high rotational speeds. The guide duct for the roving can be of enclosed shape over a maximum of its length.

Abstract: A power factor type motor controller in which the conventional power factor constant voltage command signal is replaced during a 5 to 30 second starting interval with a graduated control voltage. A ramp generator 174 provides an initial ramp-like signal which replaces a constant power factor signal supplied by potentiometer 70. The ramp-like signal is applied to terminal 40 where it is summed with an operating power factor signal from phase detectors 32, 34, and 36 to thereby obtain a control signal for ultimately controlling SCR devices 12, 14, and 16 to effect a gradual turn-on of motor 10. The SCR devices are turned on at an advancing rate with time in response to the summed or combination signal rather than simply as a function of a ramp-like signal alone, to thereby eliminate motor instabilities.

Abstract: The disclosure relates to a method for operating an ion source having a filament-cathode and an anode. Direct current electrical power is supplied between the anode and the filament-cathode characterised by substantially constant arc current therebetween and varying arc voltage on the filament-cathode. Direct current electrical power is supplied across the filament-cathode. The value of the arc voltage is monitored and the magnitude of electrical power supplied to the filament-cathode is altered in response to detected changes in the arc voltage to return the arc voltage to substantially a present reference value. The step of supplying power between the anode and the filament-cathode is done by monitoring the value of arc current flowing between the anode and the filament-cathode, deriving an arc current error signal as a function of the difference between the monitored arc current value and a present arc current demand signal, and altering the voltage supplied to the filament-cathode as a function of the arc current error signal until the monitored arc current is equal to the arc current demand signal.

Abstract: In circuit testers, notably automatic test equipment for the in circuit testing of digital devices, overheating damage can result if outputs are repeatedly 'back driven', that is whilst applying a test input to a first device, an output of a second connected device is forced into a state contrary to that it would normally adopt.The present invention provides a solution to the problem of damage by enforcing a cooling interval between backdriving test based upon a list of parameters representative of the backdriven device. In order to reduce the overall test time, a parameter is based on a measurement derived from a circuit of the type under test, and another on a subsequent backdriving test.A first test might result in device heating to a value 51 (Fig 5). A cooling interval τ<sub>coolp</sub> is enforced so that a subsequent test (resulting in heating to 54) may be made without exceeding device maximum allowable temperature T<sub>max</sub>.
