专利汇可以提供Energy stabilization in a horizontal deflection circuit for a television receiver专利检索，专利查询，专利分析的服务。并且A thyratron-like gating device governs the current supplied to an inductance in energy-exchanging relation with the storage capacitor in a reactive horizontal sweep circuit. The gating device is triggered by a control pulse that is delayed with respect to the start of the flyback portion of the sweep cycle by an amount proportional to the magnitude of the voltage stored on the capacitor at the start of flyback. The control pulse is generated upon the coincidence of a first saw-tooth voltage triggered at the start of flyback and a second voltage derived from the magnitude of the pulse generated in a secondary winding of the deflection transformer at the start of flyback. Suitable gain control facilities limit the magnitude of the second voltage to a value that assures generation of the control pulse within the flyback interval.，下面是Energy stabilization in a horizontal deflection circuit for a television receiver专利的具体信息内容。

A circuit as defined in claim 1, in which the first generating means comprises, in combination, comparator means having first and second inputs and an output adapted to exhibit a pulse upon a coincidence of voltage amplitudes applied to the first and second inputs, second means triggered at the start of the first interval for generating a first sawtooth voltage whose magnitude reaches a first value at the conclusion of the first interval, third means for generating a second voltage proportional to the magnitude of the voltage stored on the first capacitor at the start of the first interval, third means for coupling the output of the second generating means to the first input of the comparator means, and fourth means for coupling the output of the third generating means to the second input of the comparator means.

3. A circuit as defined in claim 2, in which the third generating means further comprises, in combination, a first secondary winding of the deflection transformer, and means for rectifying the output of the first secondary winding.

4. A circuit as defined in claim 2, in which the third generating means further comprises gain control means for limiting the maximum value of the second voltage to the first value.

5. A circuit as defined in claim 3, in which the third generating means comprises, in combination, second and third gating means, second and third capacitors, means for coupling the output of the rectifying means across the second and third capacitors, respectively, means for producing a third voltage proportional to the difference between the voltage across the second capacitor and a reference value, fifth means for coupling the third voltage to the control electrode of the second gating means so that such second gating means conducts when the third voltage is within a prescribed range, sixth means for coupling the voltage across the third capacitor to the control electrode of the third gating means, and seventh means for coupling the output of the second gating means to the control electrode of the third gating means, the third gating means being made conductive upon the conduction of the second gating means.

6. A circuit as defined in claim 5, in which the deflection transformer includes a second secondary winding, and in which the circuit further comprises, in combination, a common terminal for exciting the second and third generating means, a diode for coupling the second secondary winding to one terminal of the diode, eighth means for coupling the other terminal of the diode to the common terminal, and ninth means for coupling the third capacitor to the common terminal, the diode being rendered non-conductive to decouple the second secondary winding from the common terminal in the presence of voltage across the third capacitor.
