Abstract: A device for continuously manufacturing a cast strand by continuous casting of liqui metal, melt, wherein the flow of the liquid metal in the non-solidified portions of the strand is controlled by means of a static or periodic low-frequency magnetic field. A mould is adapted to be supplied with the melt. The mould comprises copper plates (2a, 2b) which form a casting mould with a rectangular cross section, water box beams (3) which are arranged outside the copper plates to support and cool them, and a member (4) holding the mould together. Magnetic field-generating devices, magnets, are provided close to the mould to generate a static or periodic low-frequency magnetic field which acts in the path of the inflowing melt and divides the primary flow as well as checks any secondary flows arising. Each magnet comprises a front core (5), a rear and a coil (7).

Title: Compact notebook computer having a foldable and collapsible keyboard structure
Inventor: SELLERS CHARLES A
IPC: H01H3/12
Filed: 1995-06-28
Granted: 1999-02-23
Abstract: A compact notebook computer, when opened, exposes a keyboard structure in a folded storage and transport orientation in which opposite end segments of the keyboard are inwardly pivoted onto a central segment of the keyboard, and the keys are in fully retracted, inoperative positions.   To use the keyboard its end segments are outwardly pivoted to a use orientation in which they project outwardly beyond opposite ends of the computer base housing and are vertically aligned with the central keyboard segment.  A top side portion of the keyboard structure is then horizontally shifted in  a  first  direction  relative  to  a  base  portion thereof.    This  shifting  automatically  raises  the keyboard keys to fully extended operative positions thereof,  thereby readying the keyboard for typing thereon.   To return the keyboard structure to its storage and transport orientation, the top keyboard side portion is horizontally shifted relative to the base portion in a second direction opposite to the first direction.  This shifting automatically retracts the keys to their original inoperative positions.  The opposite keyboard end segments are then folded inwardly onto the central segment to permit the computer lid housing to be closed again.

Title: Autostereoscopic imaging apparatus and method using a parallax scanning lens aperture
Inventor: BACS ARON JR
IPC: H04N13/221
Filed: 1994-10-26
Granted: 2004-04-20
Abstract: A lens aperture of an autostereoscopic camera is moved in a parallax scanning pattern through a plurality of disparity positions offset from the optical axis of the camera lens. Images of a scene being photographed, as viewed through the lens aperture in its various disparity positions, are recorded for subsequent display in three-dimensional illusion when viewed with the unaided eye. The size of the lens aperture and the parallax scanning pattern are adjustable to suit conditions. The lens aperture may be defined as a through-hole in an opaque card or a planar array of cells switched between transparent and opaque states. In addition to stereoscopic imaging, the moving lens aperture principle of the present invention may be utilized in range-finding and camera image stabilization applications.

Title: Integrated gps/inertial navigation apparatus providing improved heading estimates
Inventor: EBNER ROBERT E
IPC: G01C21/20
Filed: 1996-05-07
Granted: 1998-12-22
Abstract: The integrated GPS/inertial navigation apparatus utilizes satellite signals received with two spatially-separated antennas to achieve improved heading estimates for a mobile platform. Each satellite signal comprises one or more component signals with each component signal having a different carrier frequency. The integrated GPS/inertial navigation apparatus consists of a receiver and an inertial navigation system. The receiver measures the carrier phase of each of one or more component signals of one or more satellite signals received by each of the two antennas during successive time periods of duration Tp. Phase measured during a Tp time period is called Tp-phase. Only one component signal of one satellite signal received by one antenna is measured during any Tp time period. The receiver utilizes the Tp-phases of each component signal obtained during a Tk time period to estimate the phase of the component signal at the end of the Tk time period, the estimated phase at the end of the Tk time period being called the Tk-phase. The inertial navigation system, comprising inertial sensors and a digital processor, utilizes the Tk-phases in determining the heading of the vehicle and the displacement of each of the two antennas from the inertial sensors of the inertial navigation system. The measured phase of a component signal is subject to error as a result of the satellite signal traversing the ionosphere. The inertial navigation system achieves more accurate estimates of heading and antenna displacements by utilizing the Tk-phases in determining ionospheric corrections to phase.

Granted: 1999-06-15
Abstract: A railroad searchlight signal for producing light signals of selected colors.  The searchlight uses a reflector that has an inner surface of reflective material and a focal point. One or more light emitting diodes are provided at the reflector focal point.  When a current is supplied to the light emitting diode from a variable current power source, a light having a color that varies dependent upon the current is produced. The colored light produced at the light emitting diode is then directed  outward of the reflector as a beam.  At least one color filter that allows light of a respective color to pass therethrough is preferably provided proximate the reflector.  Light that passes through the color filter is  detected by a light detector such as a photovoltaic cell, a phototransistor  or a photodiode.

Abstract: An  improved  control  valve for use in  a  mixing valve  has  a valve mount,  a spindle assembly and a  water restraining plate having two outlets.  The spindle assembly has a spindle rod and a two staged valve body  having  a chamber  at  the lower portion thereof. In the  chamber  are there a  plurality of cylindrical posts,  including 4  long posts and other short posts that are arranged in order. The cylindrical posts are used to reduce the noise of turbulent flow  passing through the valve body and the 4  long  posts support  the  water restraining plate in place and  stop  a spring  biased  sealing pad from dropping into chamber  via the outlets.  Thus, the spindle rod of the spindle assembly can  be  rotated more smoothly and the  noise  produced  in operation can be minimized.

Abstract: A method of tempering an article is disclosed in which an article is heated so that the material making up the article is in an essentially stress-free state and the article thereafter is quenched and cooled. At the conclusion of the quenching, a stress pattern in initiated through the thickness of the article in which the midplane layer is in tension and the surface layers are in compression. This stress pattern is further developed during the cooling stage. The article is quenched by spraying the surfaces with a coolant, preferably comprising either liquid nitrogen or liquid air in the form of a two phase flow of liquid and vapor. The liquid is sprayed so that the surface tensile stress of the surface layers are not exceeded and the liquid does not accumulate on the surface layers as a film.

Abstract: A silicon pellet feed system for use with a silicon melt furnace used to grow a silicon web. A reservoir for containing feed particles is coupled to the upper end of a feed tube. The lower end of the feed tube is positioned adjacent a pair of rotatable drive rollers driven by a motor through a coupling and a pair of gears. The rollers are mounted at an angle with respect to horizontal and the outlet end of the roller feed path is located above a delivery tube leading to the silicon melt furnace. The elements are surrounded by an enclosure having a vacuum outlet for enabling the enclosure to be evacuated to a working vacuum level and a gas inlet for enabling an inert gas to be back filled into the enclosure. The feed rate is determined by the angle of the drive rollers, the speed of the motor and the shape of the bottom end of the feed tube. The rollers are resilient to provide enhanced surface friction for the particle flow and to prevent trapped feed particles from jamming the motor.
