An apparatus for automating building construction includes an upper panel bay and feeder, a joist array and feeder, and a lower panel bay and feeder. The machine positions each joist and upper and lower panels into an installation position where fastening means forms the structural member, which is advanced out of the apparatus.
Abstract: Phosphate esters useful for gelling hydrocarbons in combination with a metal source are disclosed along with methods of preparation of the phosphate esters. Fouling in oil refinery towers has been attributed due to distillation of impurities present in phosphate esters used to gel hydrocarbons for oil well fracturing. The improved method of preparation of the phosphate ester results in a product that substantially reduces or eliminates volatile phosphorus, which is phosphorus impurities that distill up to 250° C., and increases the high temperature viscosity of the hydrocarbon gels formed using the phosphate esters.

Abstract: The coupling includes a mandrel and a coupling outer sleeve. In a method for installing the coupling on a pipe, the mandrel is inserted into the inner diameter of an end of pipe with an outboard end of the mandrel protruding from an end of the pipe. Then the outer sleeve is positioned over the pipe to form a length of substantially concentrically arranged, overlapping parts of the mandrel, the pipe and the sleeve. Then the sleeve is crimped over at least a portion of length, which engages the pipe between the sleeve and the mandrel. Either before or after sleeve is crimped over the pipe, the sleeve is connected to the outboard end of the mandrel.
Abstract: The invention is directed to reinforced ground cover mats which can be used to facilitate the passage of heavy equipment and vehicles on wet or disturbed ground. The ground cover mats are comprised of boards contained within a metal frame. A structural support in the form of an I-beam encases the boards and frame on one side, and a tubular member such as a pipe on the other side, thereby increasing the strength at the middle of the mat ends. Further, the tubular member can be modified at its ends to facilitate insertion of a sling and stacking of adjacent mats. The mat also comprises means for lifting, including passages through which chains or cable may be threaded, lifting shackle assemblies or pear link assemblies.
Abstract: The present invention relates to the monitoring of gas concentrations possible in very low ranges (i.e., low ppb and even ppt ranges) and especially use thereof in environmental monitoring, exposure assessment, bomb detection, and health studies. The invention can use a spatial and temporal assessment of gas concentrations that enables the sources of the gas in question to be located and identified which is useful in environmental and health field but can also be applied to other fields an example of which is detecting and locating explosives. This technology can uses small, light weight, and low power components that allow for the monitor to be portable and even worn on a person as a personal monitor. This technology can be used in a stationary monitors as well.
Abstract: An isolated nucleic acid sequence encoding a non-oligomerizing Clavularia teal fluorescent protein (TFP) variant having a tyrosine-derived chromophore, and fragments and derivatives thereof. Also provided is a method for engineering the nucleic acid sequence, a vector comprising the nucleic acid sequence, a host cell comprising the vector, and use of the vector in a method for expressing the nucleic acid sequence. The present invention further provides an isolated nucleic acid, or mimetic or complement thereof, that hybridizes under stringent conditions to the nucleic acid sequence. Additionally, the present invention provides a non-oligomerizing TFP variant encoded by the nucleic acid sequence, as well as derivatives, fragments, and homologues thereof. Also provided is an antibody that specifically binds to the TFP variant. The present invention further provides a tandem dimer comprising two TFP dimers, operatively linked by a peptide linker.

Abstract: A system and method for removing a piece of tramp metal from particulate material transported by a conveyor is provided. A metal detector is used to detect tramp metal in the particulate material traveling along the conveyor. When a piece of tramp metal is detected, a redirection device positioned at the end of the conveyor is used to reject a portion of the particulate material that contains the tramp metal, by temporarily redirecting the flow of particulate material discharging from the conveyor. After the portion of particulate material containing the piece of tramp metal has been redirected by the redirection device, the system resumes normal operation.

Abstract: A multilayer contact approach for use in a planar solid oxide fuel cell stack includes at least 3 layers of an electrically conductive perovskite which has a coefficient of thermal expansion closely matching the fuel cell material. The perovskite material may comprise La1-x Ex Co0.6Ni0.4O3 where E is a alkaline earth metal and x is greater than or equal to zero. The middle layer is a stress relief layer which may fracture during thermal cycling to relieve stress, but remains conductive and prevents mechanical damage of more critical interfaces.
