Title: High frequency ferroresonant power supply
IPC: H01F27/255
Filed: 1981-07-10
Abstract: A ferroresonant power supply having a relatively stable output voltage includes a magnetic element having a saturating core (20) and a winding (22) thereon. A magnetizing current is developed by a source (23) of high frequency voltage for generating alternating magnetic flux in the core (20) so as to develop an alternating output voltage (V out). A capacitor (26) develops a circulating current that generates in a core section associated with the winding magnetic flux that aids in saturating the core section to provide regulation of the output voltage by ferroresonant action. In order to temperature stabilize the output voltage, the saturating core section is formed of a ferrospinel comprising a lithium ferrite or a substituted lithium ferrite. The ferrospinel has desirable magnetic properties of a relatively small change in saturation flux density with temperature, and low coercivity which results in a relatively small temperature rise in the saturating element. The ferroresonant power supply may be used to generate an ultor voltage for a picture tube in a television receiver.

Patent ES-8500427-A1 (ES)
Title: Apparatus for the continuous desublimination of vapors of subliming substances
IPC: C07C51/573
Filed: 1983-07-22
Abstract: A continuous, desublimination apparatus capable of operating at high flow rates. The apparatus works on the principle of reducing temperature of a vapor-gas mixture below the desublimination point. It has a heated jacket with inlets and outlets of gases in which a gas permeable wall is coaxially spaced. Said wall encloses a desublimination space with nozzles for atomizing an evaporable liquid and with a distributor of a vapor-gas mixture at the inlet. The space between said gas permeable wall and the inner jacket wall is divided into at least three vertically aligned sections, the volumes of which increase in the direction away from said inlet of the vapor-gas mixture. In operation, a vapor-gas mixture is cooled below the desublimination point by an atomized liquid. Simultaneous blowing of a secondary gas through said gas permeable wall protects the wall of said desublimination space from solid deposits. The solid condensate is recovered from the gas phase in a separator, gas given off during operation of the apparatus leaves the apparatus, and the solid product is discharged from the apparatus as by a conveyer.
