Title: Circuit for correcting setup error in a color television receiver
IPC: H04N3/23
Filed: 1978-02-14
Abstract: A horizontal deflection circuit of a color television receiver includes a horizontal output transformer with a secondary winding across which a voltage is developed and includes a horizontal deflection winding coupled to a pincushion correction winding of a pincushion reactor. In response to the current flowing in the vertical deflection winding, the inductance of the pincushion correction winding varies in a manner providing for East-West pincushion distortion correction. For setup, in the service mode of operation, the vertical deflection circuit is disabled. A circuit, coupled to the pincushion reactor, adjusts the inductance of pincushion correction winding to compensate for a change in the inductance caused by disabling of the vertical deflection circuit for maintaining the voltage across the horizontal output transformer secondary winding substantially unchanged during setup.

Title: Apparatus for mixing additional gas into a main flow of gas.
IPC: B01F23/10
Filed: 1980-05-09
Abstract: Gas is mixed into a main flow of gas in a cylindrical conduit by means of one or more feed conduits. In order to achieve good mixing and avoid concentrations of the added gas, the feed conduit(s) have two openings for outflow of the added gas, which openings are spaced from the wall of the cylindrical conduit, are symmetrically located with respect to the axis of the cylindrical conduit and lie in a plane perpendicular to that axis. The axis of these openings are mutually spaced by less than one half of the internal diameter of the conduit. The added gas emerges from the two openings in mutually opposite parallel directions, so that it tends to circulate around the axis. The arrangement has been found advantageous when applied to the feed of gaseous fuel to hot blast stoves of a blast furnace.

Patent ES-8405999-A1 (ES)
Title: Process for fabricating an optical device.
IPC: H01L33/30
Filed: 1983-09-08
Abstract: This invention is a process for fabricating optical devices by photoetching geometrical shapes on the surface of an n-type or intrinsic compound semiconductor so as to yield surfaces of optical quality without further processing. The etching process is an electrochemical process where etching is proportional to light intensity. The process involves applying a potential to the compound semiconductor while immersed in an electrolytic solution containing hydrofluoric acid and irradiating the surface to be etched with light in a certain energy range. The distribution of light intensity and ray direction is selected to produce the desired geometrical shape. Particularly advantageous is that the surfaces produced are of optical quality. For example, lenses produced by the etching process exhibit surfaces of optical quality. Further, the process can be carried out on all the lenses on a wafer simultaneously without attention to individual devices. This is highly desirable economically. Also, the lenses produced are integral parts of the light emitting diode.
