Title: Switching arrangement for flesh tone correction and chrominance overload control circuits

Abstract: SWITCHING ARRANGEMENT FOR FLESH TONE CORRECTION    AND CHROMINANCE OVERLOAD CONTROL CIRCUITS              Abstract of the Invention Switching apparatus is included in a color television receiver for changing the threshold of a saturation overload detector and simultaneously changing the gain characteristics of an associated chrominance signal amplifier.  The overload detector is operative to limit chrominance signals at a lower level when noisy signals are present and at a higher level when relatively noise-free signals are present.  The switching apparatus is arranged to avoid annoying large shifts in picture saturation upon its operation.  An associated flesh tone correction circuit is enabled by the switching apparatus when the lower overload limit is employed and is disabled when the higher limit is employed.

Abstract: ABSTRACT OF THE DISCLOSURE:           A new method of effecting flotation of mineral grains on a laboratory scale is provided, wherein a mineral sample of uniform grain size and uniform mineral composition is condi-tioned to produce a definite degree of adsorption and then subjected to flotation.  The floating mineral grains are separated at time intervals to let the flotation rate coeffi-cient to be determined.  On the basis of this procedure a method of constructing a continuously operable flotation concentration plant was developed.  This method comprises repeating the laboratory scale flotation a plurality of times using a different degree of adsorption in each case, which enables the relationship between the degree of adsorption and the flotation rate coefficient to be determined.  Thereafter the same procedure is repeated so that all the different grain sizes and mineral compositions present in the material to be handled are covered.  The resulting relationships are then used in a simulation procedure, where the distribution of the material in a continuous flotation concentration process is determined, and finally the concentration plant is constructed in accordance with this determination.

Abstract: ABSTRACT OF THE DISCLOSURE     An actuator for a rotating frame animal trap having two similar frames pivotaly connected to each other.  The actuator comprises two arms spring biased at one end and each terminating in a ring at the other.  The rings have the dimensions so that the actuator can be mounted on the trap to encircle adjacent ends of both frames of the trap.    On release of the trap, the actuator can rapidly and forcefully effect a rotation of the trap to its closed position.  A rigid joint is formed in one arm of the actuator.  The joint is breakable to separate the one arm by application of a force to the spring biased end of the actuator.  The actuator does not affect the position of the set trap and is simple in construction.

Abstract: ABSTRACT OF THE DISCLOSURE    A high frequency generator projects an electronic wave into a control zone under surveillance to establish a first field.  A frequency modulated (FM) generator is used for establishing a second field throughout the zone.  A third field of the same FM carrier frequency, but with a different modulation, is established only at extreme ends of the control zone to define the limits of the control zone.  Presence only within the control zone of a transponder causes the reradiation of a signal comprised of the FM signal and the high frequency signal, which in turn activates an alarm circuit.

Abstract: ABSTRACT OF THE DISCLOSURE            The disclosure describes a technique for uniform heating of relatively large blocks of hydrocarbonaceous forma-tions is situ using radio frequency (RF) electrical energy that is substantially confined to the volume to be heated and effects dielectric heating of the formations.  An important aspect of the disclosure relates to the fact that certain hydrocarbonaceous earth formations, for example raw unheated oil shale, exhibit dielectric absorption characteristics in the radio frequency range. In accordance with the system of the invention, a plurality of conductors are inserted in the formations and bound a particular volume of the formations.  The phrase "bounding a particular volume" is intended to mean that the volume is enclosed on at least two sides thereof.  Electrical excitation is provided for establishing alternating electric fields in the volume.  The frequency of the excitation is selected as a function of the dimensions of the volume so as to establish a substantially non-radiating electric field which is substantially confined in the volume.  In this manner, volumetric dielectric heating of the formations will occur to effect approximately uniform controlled heating of the volume.
