Abstract: COLOR HUE CONTROL CIRCUIT FOR COLOR TELEVISION RECEIVER             ABSTRACT OF THE DISCLOSURE        A color television receiver having a color picture tube with a screen for displaying a color picture in response to the reception of a composite color television signal which includes a phase reference signal, such as, the chrominance reference portion of a VIR signal, is provided with a circuit for generating variable reference color signals and for causing the color picture tube to display, on at least a portion of its screen, areas of respective colors corresponding to the variable reference color signals, a demodulating circuit for demodulating the phase reference signal and the chrominance component of the color television signal for obtaining demodulated color signals from such chrominance component, a hue correction circuit responsive to the demodulated phase reference signal for correcting errors in the hue of the color picture displayed on the screen in correspondence to the demodulated color signals due to phase distortions in the chrominance component of the received color television signal, and a manually actuable hue adjuster for simultaneously and correspondingly varying the relation of the demodulated color signals to each other and the relation of the variable reference color signals to each other so that the hue of the areas of colors displayed on said screen will correspond to the hue of the color picture displayed on the screen.  The color television receiver is further provided with a circuit for generating fixed standard color signals having a relation to each other representing a predetermined standard hue, and for causing the color picture tube to display, on a second portion of its screen adjacent the first mentioned portion of the screen, areas of primary colors corresponding to the standard color signals so that the relation of the hue of the displayed color picture to the standard hue can be readily determined by visual comparison of the areas of colors on the first portion of the screen with the respective areas of primary colors on the adjacent second portion of the screen.

Abstract: INTEGRAL SPRING PISTON RING               Abstract of the Disclosure A one-piece annular oil control piston ring for internal combustion engines is adapted to be received with a peripheral groove in a piston.  The ring is of generally U-shaped cross section defined by a pair of opposed sidewalls which project inwardly of the ring from a central peripheral wall thereof.          A pair of scraper rims projects outwardly of the ring from the outer face of the peripheral wall.  Spring members are cut from the peripheral wall and project between the sidewalls inwardly of the ring a distance sufficiently inwardly of the sidewall edges to enable the spring members to engage the back wall of the piston groove in which the ring is disposed.  The spring action of the spring members biases the piston ring outwardly of the groove so that the scraping rims are maintained in scraping engagement with the cylinder walls.

Abstract: IMPROVEMENTS IN SOLAR ENERGY COLLECTORS          ABSTRACT OF THE DISCLOSURE    A solar energy collector comprises a closed envelope formed from two sheets of material sealed together around their peripheral edges and spaced apart to define a space adapted to be filled with a working fluid and opening into a vapour space into which the working fluid can vaporize when heated by exposing one surface of the envelope to solar radiation.  At least one condensing tube is provided in heat exchange relation-ship with the vapour space and through which liquid to be heated flows.  At least one of the two sheets is formed to provide, in combination with the other sheet, at least one condensate return channel for returning condensed vapour from the vapour space to the working fluid space.  The result is a collector that can operate more efficiently than conventional collectors.

Abstract: 47,246 VAPORIZATION COOLED AND INSULATED  ELECTRICAL INDUCTIVE APPARATUS     ABSTRACT OF THE DISCLOSURE         Electrical inductive apparatus cooled and elec-trically insulated by a vaporizable liquid dielectric having a boiling point within the normal operating temperature range of the apparatus.  When the electrical inductive apparatus is at ambient temperature, the liquid dielectric completely fills the enclosure providing electrical insula-tion for the electrical members.  As the temperature of the apparatus increases towards its normal operating range, the liquid dielectric is gradually withdrawn into a reservoir until, at the normal operating temperature, only a quantity of liquid dielectric sufficient to completely cover the electrical inductive apparatus remains in the enclosure.  In response to a temperature decrease, the liquid stored in the reservoir is gradually returned to the enclosure thereby maintaining a constant level of dielectric strength between the electrical members.

If the instrument player selects the root/fifth  mode of operation and the combination of depressed keys is not a recognizable chord pattern, the system provides a low-high select routine with the notes corresponding to the lowest and highest frequency keys actually depressed.  The input to the chord pattern detector is optionally provided by a one finger chording system.  The instrument player can disable the automatic bassline operation and select an optional high note manual pedal bass note system operation.
