A high efficiency gasification process for converting carbonaceous solids to methane and apparatus for its practice are described. The process includes reacting steam and carbonaceous solids comprising ash in the presence of alkali metal catalyst in a gasification reactor to produce combustible gases and char particles comprising ash and alkali metal catalyst constituents, treating a stream of such char particles in an alkali metal catalyst recovery system to recover the catalyst constituents as alkali metal compounds, and recycling such recovered compounds. Within the alkali metal catalyst recovery system the process includes quenching the stream of char particles with water whereby such particles are cooled and fractured, dissolving soluble alkali metal catalyst constituents from the fractured solids to form a first alkali metal catalyst solution and washed solids, optionally reacting the washed solids in alkaline solution to form a second alkali metal catalyst solution, upgrading said first and optional second alkali solution to recover the alkali metal catalyst constituents as said alkali metal compounds.

An omni-directional camera array that is very small and unobtrusive and allows for higher pixel resolution for the face of meeting participants sitting or standing around a conference room table, as would be typical in a video conferencing situation. The camera system of the invention uses N cameras and an N sided mirror to capture images of the surrounding scene. The cameras are arranged to have a small distance between their virtual centers of projection. The images from the N cameras are stitched together to create a 360-degree panorama using a calibration surface. To stitch the images together in real-time, a static image stitcher is used, which stitches images together perfectly for objects on a calibration surface. The calibration surface is typically defined by the boundary of the table the camera is sitting on.

A freezer arrangement includes a room having a storage area and a blast cell, with the volume of the storage area being greater than the volume of the blast cell. Frozen food product is positioned in the storage area. A refrigeration unit draws air from the storage area and through the blast cell to rapidly freeze the unfrozen food product. Air from the blast cell is chilled and blown back into the storage area. A method for rapidly freezing unfrozen food product includes providing a room with a large storage area and a smaller blast cell. Unfrozen food product is loaded into the blast cell and a refrigeration unit is operated to draw air from the large storage area, through the blast cell, chill the air, and exhaust the chilled air into the storage area, until the food product in the blast cell is cooled to a predetermined temperature.

An information handling system mezzanine circuit board disposed in a parallel configuration over a motherboard is selectively coupled and de-coupled at the motherboard with a retraction and latching device that translates retraction force applied at an accessible actuation portion to push upward from below the mezzanine circuit board. A retraction portion of the retraction and latching device provides an upward force at the bottom surface of the mezzanine circuit board to separate the mezzanine circuit board connector from the motherboard connector so that an end user can lift the mezzanine circuit board away from the motherboard.

A klystron has a hollow beam electron gun that has a circular planar electron emitting surface. A hollow electron beam is directed from the electron gun through a plurality of drift tubes, resonant chambers and magnetic fields to a collector. The hollow electron beam does not experience significant radial movement and can operate at a lower beam voltage which reduces the required length of the RF interaction circuit and lowers the risks of RF arcing.

Either an umbilical cord connection or a wireless communication link can be provided for dynamically determining the distance and orbital positioning of the robot relative to the base station.

Synthetic fiber composites (preferably containing nylon fibers obtained from recycled carpets) are made in laminated forms that can substitute for wooden boards, and even for structural beams (including studs, rafters, joists, etc.) in a framed house or other building. These laminates can be made from needle-punched fiber mats, which provide more extensive fiber intertwining than air-laid, bat-formed, or other fiber mats. In a preferred method of manufacture, sheets or wide strips are glued together, under pressure and using a non-foaming adhesive, to form oversized laminates having any desired thickness and desired length. The laminated sheets or strips are then sawed (such as by gang-ripping) into desired widths, to form edges that will not need additional trimming to remove excess adhesive. If suitable adhesives are used to form the adhesive layers, lamination can provide increased stiffness, compared to single-layer sheets having the same thickness. This increased stiffness can provide these laminated items with greater ability to withstand bending moments, torsional forces, and heavy longitudinal compression. These materials can also enable improved building designs and constructions that use less material, such as by increasing the spacings between adjacent studs, joists, and rafters.

The present invention provides a flow-through photobioreactor containing at least one thermoplastic multi-wall sheet having an upper layer and a lower layer having arranged there between at least two sidewalls, at least one inner wall and two or more end caps. Also provided is a process for the production of a biofuel with the inventive photobioreactor. The photobioreactor and process of the present invention have the following advantages: genetically engineered microbes that give higher yields cannot escape into the environment, water in the system does not evaporate, no weeding (presence of unwanted algae), UV light from the sun is filtered out by the reactor walls, temperature control is possible, CO2 from power plants, breweries, etc. can be artificially fed to increase yield. The inventive photobioreactor is also less expensive to build than pipe reactors and may have low energy costs to operate, because little or no energy is needed for agitation and pumping in a preferred gravity assisted embodiment.

An underwater structure inspection vehicle that uses a rotating brush to clean the structure for camera inspection. Unlike underwater vehicles currently being used that are positioned by thrusters, this vehicle will be positioned in three different planes by three different means. The first is by mechanically raising and lowering it. The second is by a propulsion system pushing it into the structure. The third is by lateral guidance bars being engaged by the rotating forces of the propulsion system. In areas of high water velocity, an optional back-side platform may be used to assist the propulsion system by locking the vehicle onto the structure.

An outdoor electronic screen protection device includes a nonhermetically sealed housing. A mounting system attaches the nonhermetically sealed housing to a wall of a structure. An access port is provided in the nonhermetically sealed housing. A non-transparent front cover is attached to the housing. A locking mechanism is attached to the nonhermetically sealed housing. The protection device does not include any active environmental control systems. When the user wishes to view the electronic screen the front cover is opened. As a result, the user does not have to look through an additional window to view the electronic screen, which causes glare. Since the housing is not hermetically sealed, it is considerably less expensive to build than previous devices.
