A fireproof insulating foamed cementitious composition with thermal energy storage capacity is provided for use in producing wall insulation boards, fireproof claddings for steel structures, inner cores of fire resistant wall or door panels, and the like. The composition demonstrates improved energy efficiency in which phase change materials, such as microencapsulates, are used in conjunction with a cementitious mixture of calcined gypsum and hydraulic cement, lightweight aggregates, a polymer latex, and a foaming solution to create stable air bubbles inside the cementitious matrix. The calcined gypsum and the hydraulic cement are present in a weight ratio range from about 1:3 to about 3:1. The composition may further include reinforced fibers, surfactants, inorganic flame retardants, and other additives. The presence of the phase change material not only increases energy efficiency of the cured cementitious foam material, but also improves compatibility between calcined gypsum and cement during slurry mixing and hardening.

Disclosed is a process for reclamation of waste fluids. A conditioning container is employed for receipt of waste material on a continuous flow for treatment within the container by immersible transducers producing ultrasonic acoustic waves in combination with a high level of injected ozone. The treated material exhibits superior separation properties for delivery into a centrifuge for enhanced solid waste removal. The invention discloses a cost efficient and environmentally friendly process and apparatus for cleaning and recycling of flowback, or frac water, which has been used to stimulate gas production from shale formations. The apparatus is mobile and containerized and suitable for installation at the well site.

The invention relates to a spur gear differential (66) comprising a housing (68) that is embodied as a sum wheel (50) and that rotates around a longitudinal rotational axis (4), at least three planet gears (21, 22) disposed on the periphery at a distance in relation to each other around the rotational axis (4), and a drive wheel (67) at the housing (68), with

• • the housing (68) comprised of at least two housing sections (75) fixed to each other,
  • each of the planet gears (21, 22) mounted longitudinally on both sides in the housing sections (75),
  • at least one of the housing sections (75) formed in the shape of a pot, with the housing section (75) formed from a pot (76) having a base (65) arranged on the front side of the housing, a wall starting from the base (65) and extending around the rotational axis (4)

A polymeric material suitable for making a substrate for optical data storage disks is disclosed. The material, preferably aromatic polycarbonate is characterized in that the potential on 95 to 100% of the total surface of a disk molded therefrom is from −1.5 to +1.5 kV, and in that the potential on 0 to 5% of the total surface of said disk is between −1.5 and −2.5, and +1.5 to +2.5, and in that the potential on no more than 1% of the total surface of said disk is less than −2.5 kV and more than +2.5 kV. The potential measurements are carried out by means of a Monroe probe at a distance of 3.5 mm from the surface of the disk, the scanning region is in each case 12 cm in the X- and Y-direction, and in each case in steps of 2 mm in the X- and in the Y-directions.

A method for producing methanol from a methane source such as methane from natural (shale) gas by first reacting one equivalent of methane with oxygen from the air to result in complete combustion to produce carbon dioxide and water in a molar ratio of 1:2; then conducting a bi-reforming process with a mixture of methane: carbon dioxide:water having a ratio of 3:1:2 to produce metgas, a mixture of hydrogen and carbon monoxide having a molar ratio of 2:1 to 2.1:1; and finally converting metgas exclusively to methanol. The thus produced methanol can be dehydrated to form dimethyl ether, with water produced being recycled back to the bi-reforming process, if necessary.

One or more embodiments of the present disclosure are directed to packages that include a stacked microelectromechanical sensor MEMS die and an application-specific integrated circuit (ASIC) die. The smaller of the MEMS die and the ASIC die is stacked on the larger of the MEMS die and the ASIC die. The larger of the two dice may form one or more dimensions of the package. In one embodiment, a bottom surface of the larger of the two dice forms an outer surface of the package. In that regard, the package may take less lateral space on another component, such as a board or other package.

A multi-stage bit stream multiplexer that divides multiplexing functions between two or more integrated circuits. The first integrated circuit receives 16 bit streams to produce 4 output bits streams with a nominal data rate of 10 GBPS. A second integrated circuit multiplexes the 4 streams and to a bit stream with a data rate of 40 GBPS. The first IC is made in a standard CMOS process while the second IC is made using processes that support higher switching rates. The first IC produces a source-centered double data rate forward transmit clock from a reference clock selectable from either a crystal oscillator, a voltage controlled oscillator using a loop clock from the receive side of the bit stream multiplexer or a reverse clock generated by the second IC. The reverse clock can be selected as the source of the reference either by default, or in response to a specific condition.

A metallic article made of metallic constituent elements is fabricated from a mixture of nonmetallic precursor compounds of the metallic constituent elements. The mixture of nonmetallic precursor compounds contains more of a base-metal element, such as nickel, cobalt, iron, iron-nickel, and iron-nickel-cobalt than any other metallic element. The mixture of nonmetallic precursor compounds is chemically reduced to produce a metallic superalloy material, without melting the metallic superalloy material. The metallic superalloy material is consolidated to produce a consolidated metallic article, without melting the metallic superalloy material and without melting the consolidated metallic article.

The invention relates to a submersible power plant. The power plant comprises a structure and a vehicle. The vehicle is arranged to be secured to the structure by means of at least one tether. The vehicle is arranged to move in a predetermined trajectory by means of a fluid stream passing the vehicle. The vehicle comprises a first wing and a second wing, where the first wing is arranged at a first distance D1 from the second wing in a longitudinal direction, and the first wing is arranged at a second distance D2 from the second wing in a lateral direction.

The present invention relates to a method of extracting a pigment from microalgae.
