摘要： The time piece includes seven-bar-segment digital time indicating displays, the segments being selectively actuated by a time indicating source through a logic circuit. In one form, the display face includes a clear front glass, a dark back reflector glass spaced from the front glass, liquid crystals disposed between the glasses and an electrode material formed on the back glass with portions thereof removed while the remaining portions form electrodes for the seven bar segments. Selected energization of the electrodes energizes the liquid crystal segments to provide a light scattering effect whereby light incident to the energized liquid crystal segments is reflected to provide a digital display against a dark background. A nuclear powered light source surrounds the display face to provide light incident to the energized liquid crystals for digital display under dark conditions. In another form, the front glass is coated white except for the segments and a nuclear powered light source is located behind the rear clear glass plate on which the electrodes are carried. In the daytime, the energized bar segments reflect light rendering the same indistinguishable from the white opaque surface whereby the natural dark color of the nuclear light source appears through the nonenergized and transparent liquid crystal bar segments providing a daytime digital time display. For night-time display, the nuclear powered light source transmits light through the nonenergized liquid crystal bar segments to provide the digital time display.

摘要： A circuit for multiplexing or energizing the crystals of a nematic liquid crystal display in timed sequence. Complementary MOS transistor logic circuits are used to create an equal potential at the opposite ends of these liquid crystals that are to be deenergized. The remaining liquid crystals are energized through direct paths or through paths in series with other energized crystals.

摘要： Disclosed is a solid state watch which requires no moving parts for timekeeping and display. The watch comprises a crystal controlled oscillator connected through an intergrated circuit binary frequency divider to an electro-optical display in the form of light emitting diodes. The display is energized only on demand and the level of the light output is controlled in accordance with ambient light conditions. The watch is energized from a rechargeable battery.

摘要： Disclosed is a solid state wristwatch incorporating a nuclear timing source. A radioisotope such as Radium 226 decays, producing alpha particles that are detected and converted into electrical pulses of constant frequency. The electrical signals are divided in a CMOS binary chain and used to drive a digital time display of light emitting diodes. The watch is powered by a conventional 3 volt battery.

摘要： Disclosed is a device useful by an orthodontist for expanding a human palate. It comprises a stationary body secured to an anchor tooth on one side of the palate and a movable block secured to an anchor tooth on the other side of the palate. A helical spring urges the two apart to expand the palate. A keeper holds them together until they are fixed in place by the orthodontist.

摘要： Disclosed is a permanent magnet tooth straightener. Nuts are attached by bands to an anchor tooth and a mobile tooth. Screws are threaded into each nut and axially aligned. The screws are permanent magnets so that their adjacent ends form interacting magnet poles which may either attract or repell each other. As the position of the mobile tooth changes the screws may be rotated to adjust the magnetic force acting between the teeth.

摘要： Disclosed is an electronic wristwatch having no moving parts and incorporating a light-responsive solid-state control circuit for the time display. An electro-optic digital display in the form of light-emitting diodes is switched off when the ambient light falls below a predetermined level. The display is also turned off when the light is too bright and it is provided with a manual override switch for actuating the display under dark conditions at the option of the wearer.

摘要： Disclosed is a permanent magnet generator or alternator of very small size and compact construction. A rare earth - cobalt permanent magnet rotor is received within a core of unitary laminations. Surrounding a pair of opposed core legs are a pair of rectangular cores. The entire assembly is slipped into the cup of a two-piece plastic housing to provide a simple and easily assembled unit.
