Abstract: CURRENT CONTROL CIRCUIT FOR HORIZONTAL DEFLECTION COIL OF TELEVISION RECEIVER       ABSTRACT OF THE DISCLOSURE         In a circuit for controlling the current flow through a coil, such as, the horizontal deflection coil of a television receiver, a first switching circuit including a first switching transistor and a first damper diode is connected in parallel with a first resonant circuit including a first capacitor and a first coil which is the coil through which the current flow is to be controlled, a second switching circuit including a second switching transistor and a second damper diode is connected in parallel with a second resonant circuit including a second capacitor and a second coil, a charging capacitor is connected in a common current path for the first and second resonant circuits, and switching signals of the same frequency, for example, the horizontal frequency of a video signal, are applied to the first and second switching transistors with the phase difference between such signals being controlled to vary the voltage across the charging capacitor and hence the current flowing through the first coil.  The phase difference between the switching signals is varied or modulated by a parabolic correcting signal having the vertical rate or frequency of a video signal in the case where a side pin-cushion distortion of the raster of a cathode ray tube is to be corrected, or the phase difference can be modulated by a correcting signal corresponding to the electron beam current or anode voltage in the cathode ray tube so as to stabilize the horizontal dimension of the raster.

Abstract: ABSTRACT   Apparatus for simulating the playing of golf includes a tee area from which a player may drive a golf ball toward a curved target screen in front of the tee area. Optical sensing devices are positioned to gather data as to the time and horizontal location at which a driven ball passes through each of three planes spaced apart between the tee area and the screen, and the horizontal location at which the ball rebounds from the screen through the plane closest to the screen. With the data from the sensing devices, computer apparatus produces an estimate for display of the distance of travel and ultimate testing position the driven ball would have if allowed free flight. Use of sensing devices for detecting passage of a driven ball through three different planes and for detecting the rebound angle of the ball from the screen enables determination of the amount of hook or slice a driven ball would have. A television camera 18 positioned on one side of the tee area, and a grid pattern is positioned on the other side to provide  a background and gauge against which movement of a player photographed for instant replay may be measured.

Abstract: ABSTRACT OF THE DISCLOSURE          A method for the detection and identification of uranium bearing materials in media found in nature such as rocks, soils, surface and sub-surface waters, vegetation, or in material which has been subjected to physical or chemical processing comprises the steps of:  irradiating the media with a light, having a single wavelength or narrow band of wavelengths in the range of about 2400 to 5000.ANG. for a time equal to or less than about 100 microse-conds; waiting for a period of time, which is dependent on twice the distance of the light-source to the irradiated medium, followed by measurement of the intensity and decay time of the luminescent light emitted by the irradiated media in 2 narrow spectral range, having a wavelength greater than the wavelength of the light used to irradiate the media. The method is useful for remote geochemical prospecting for uranium using laser induced luminescence and in monitoring products and effluents from installations processing or utili-zing uranium compounds, such as in elemental or isotopic separ-ation, purification, recovery and ore beneficiation.

Abstract: A B S T R A C T      Method and apparatus for inducting isotopically selective photoexcitation of atoms in at least first and second energy steps.  The total energy change accomplished by the two energy steps is provided with isotopic selectivity at pre-cise resonance for the two steps.  In an isotope separation system in which an environment of particles of plural isotope types is created, isotopically selective photoexcitation from laser radiation is shown to produce  a great improvement in excitation efficiency where the radiation is controlled in the aggregate of plural photons to achieve precise resonance over the plurality of the degenerate energy steps.  Even with multimode excitation, precise resonance is only achieved for isolated atoms, and a chirp or frequency sweep is applied to one of several excitation frequencies to insure precise resonance at least once for each atom.  In the case of excitation in plural transitions from plural low-lying energy through a generally common upper producing the common chirp may be applied to the radiation producing the common upper level transition alone.
