Laser sheets move back and forth evenly injecting heat into items being cooked.

The invention relates to a nuclear plant in which the power of a nuclear reactor is controlled via demand of a connected electric grid. A naturally circulating nuclear reactor coolant loop is linked to a water/steam loop by means of a steam generator. The water/steam loop consists of an electric power generating unit and a water recirculating and steam control system. The generator is coupled to an external power grid. As power requirements of the grid change, a controller linked to the generator and a three way valve divides steam flow between the expansion turbine and a feedwater heater to boost or retard the power output. Altering the steam flow changes the pressure and temperature in the water/steam system and thus the coolant flow rate. The change in coolant flow allows the reactor core to regulate its reactivity to reach a state of equilibrium to the demand for electric power.

Diffusion bonding of silicon carbide using iridium and hermetic silicon carbide-iridium bonds
An exemplary method of bonding of silicon carbide and objects having a hermetic silicon carbide-iridium-silicon carbide bond. The method includes the steps of inserting an iridium foil between two SiC layers; heating the iridium foil and SiC layers at a temperature of 1500 C in a vacuum of <10−5 ton; applying a pressure between 1 ksi and 7 ksi to the iridium foil and SiC layers; maintaining the temperature and pressure for 6-10 hours; and forming a hermetic seal having a leak rate <3×10−9 cm3/sec between the iridium foil and the two SiC layers. The SiC-iridium bonds lack cracks and are hermetic.

A high performance superconducting undulator magnet is provided. The superconducting undulator magnet includes inset grooves in which magnetic poles are attached. The superconducting undulator magnet also includes clips for use in winding. The superconducting wire is wound such that the each revolution of the wire has a precise position within each of the grooves, the precise position being repeated in each groove. The superconducting undulator magnet provided will have a mechanical precision to preserve uniformity of the magnetic pole width and coil grooves. The undulator system provides uniformity of the undulator gap.
A congestion management protocol that can be used for small messages in which the last-hop switch determines the congestion of the end point. The last-hop switch drops messages when the end point is congested and schedules a retransmission. A second congestion management protocol transmits small messages in a speculative mode to avoid the overhead caused by reservation handshakes.
2/P is greater than 200 g/atm. The brine is held at greater than 200 g/atm for longer than 20 minutes suppressing the chlorine as dissolved ions while lithium precipitates out as lithium carbonate. The lithium carbonate precipitate is removed from the brine solution.
A single-heating stage method for reclaiming or recovering metals like nickel and vanadium from a petroleum waste byproduct has three steps: melting the petroleum waste byproduct in a reducing atmosphere, generating agglomerated metal in the melted byproduct, and lifting the agglomerated metal to an exposed surface of the melted byproduct. The metal precipitates out of the molten byproduct, agglomerates into a separate portion, and rises to an exposed surface of the melted petroleum waste byproduct even though the metal may have greater density than the molten petroleum waste byproduct. The original petroleum waste byproduct stratifies into a byproduct remnant and the agglomerated metal disk. The agglomerated metal disk is separable from the byproduct remnant and may be additionally separated into constituent metals in those embodiments with multiple metals in the disk.
