Abstract: Improved negative electrodes can comprise a silicon based active material blended with graphite to provide more stable cycling at high energy densities. In some embodiments, the negative electrodes comprise a blend of polyimide binder mixed with a more elastic polymer binder with a nanoscale carbon conductive additive. The silicon-based blended graphite negative electrodes can be matched with positive electrodes comprising nickel rich lithium nickel manganese cobalt oxides to form high energy density cells with good cycling properties.

Abstract: A composite coated form of lithium cobalt oxide is described that can achieve improved cycling at higher voltages. Liquid phase and combined liquid and solid phase coating processes are described to effectively form the composite coated powders. The improved cycling positive electrode materials can be effectively combined with either graphitic carbon negative electrode active materials or silicon based high capacity negative electrode active materials. Improved battery designs can achieve very high volumetric energy densities in practical battery formats and with reasonable cycling properties.

Abstract: An arrangement for cleaning gas includes a centrifugal separator and pre-separation unit. The centrifugal separator includes a stationary casing, enclosing a separation space through which a gas flow is permitted, a gas inlet extending through the stationary casing and permitting supply of the gas from the pre-separation unit, a rotating stack of separation disks, a gas outlet and a drainage outlet for discharging separated liquid impurities. The pre-separation unit is arranged upstream of said inlet of said centrifugal separator, and it comprises a pre-separation inlet having a cross-sectional area A2 and permitting supply of the gas to be cleaned. A2 is larger than the cross-sectional area A1 of the inlet to the separation space of the centrifugal separator. A pre-separation outlet permits supply of gas from the pre-separation unit to the gas inlet of the centrifugal separator.

Abstract: A wellbore perforating device includes at least one perforating charge and an initiator. The initiator can include a ballistic train adapted to fire the at least one perforating charge. The ballistic train can include a detonator and a detonator cord. A ballistic interrupt shutter can be disposed between the detonator and the detonator cord. The ballistic interrupt shutter can prevent firing of the detonator cord.

Abstract: A centrifugal separator for separating a liquid phase from crankcase gases of an internal combustion engine includes a separation chamber, a rotor shaft, a rotor inside the separation chamber, an inlet for crankcase gases, a gas outlet, and a liquid outlet for separated liquid phase. The centrifugal separator also includes a liquid outlet chamber, a check valve, and a rotating member. The liquid outlet chamber forms an individual chamber and is arranged in fluid communication with the separation chamber via a liquid passage. The rotating member is connected to the rotor shaft and is arranged inside the liquid outlet chamber. The liquid outlet forms an outlet of the liquid outlet chamber. The check valve is arranged in the liquid outlet.

Abstract: A burner is disclosed for generating flame and heat. The burner includes a first stage, a second stage downstream of the first stage, a third stage downstream of the first and second stages, and a fourth stage downstream of the first, second, and third stages. The first stage comprises a first innermost air chamber and a first mixing chamber for air and fuel, wherein the first stage includes separate conduits for air and fuel, and wherein the air and fuel begin to mix in the first mixing chamber during use to form an air/fuel mixture. The second stage comprises a second mixing chamber which comprises a deflection plate to force the air/fuel mixture outward from the centerline. The third stage comprises a combustion zone. The combustion zone includes a swirl generator. The swirl generator has an inner diameter greater than an outer diameter of the deflection plate. The swirl generator produces a swirl, whirl, vortex, or the like in the flame during operation.

Abstract: The present invention relates to novel methods for the identification of specific mite species in a sample, such as mass reared sample or an environmental sample. The invention further relates to nucleic acid molecules encoding the structural ribosomal RNA elements (rRNA) as well as to the non-functional RNA situated between such structural ribosomal RNAs of specific mite species and its use for designing primers for use in the method.

Abstract: Embodiments may take the form of a perforating gun of modular assembly. The perforating gun may include at least one centralizing member at an interface between a loading tube and a carrier. Among modular components, the gun may also include an initiator assembly module that is electrically coupled to a modular feedthrough with a connector. The insert and the centralizing member may enhance axial cohesiveness of the modular gun. A shock absorbing mount may be located within the carrier and may receiving the initiator assembly module to provide added axial cohesiveness to the modular gun.
