Abstract: A method and device for estimating a density value ?m indicative of a true density ? or for estimating a viscosity value ?m indicative of a true viscosity ? of a fluid is disclosed. For this, a first resonance frequency fR of a first mechanical oscillator in a reference volume and a second resonance frequency fF of a second mechanical oscillator in contact with the fluid are measured. The estimated value ?m or ?m is then derived using these resonance frequencies fR and fF. During this derivation, at least one fluid-temperature- or fluid-pressure-dependent parameter of the fluid is used. Additionally or alternatively, the first (i.e. reference) mechanical oscillator is arranged in contact with a reference fluid. Thus, fundamental errors in the derivation of the estimated value ?m or ?m are reduced and the estimated value becomes more reliable.

Abstract: A method and device for operating a fluid-insulated electrical apparatus. The insulation fluid of the electrical apparatus includes at least two components. The method includes the step of determining a physical state of the insulation fluid by measuring at least three measurement variables with sensors. The method further includes the step of deriving trend variables indicative of changes over time for the measurement variables and/or for characterizing variables. These characterizing variables are derived from the measurement variables by using a relating equation, such as an equation of state, and are also indicative of the physical state of the insulation fluid. By testing for specific patterns of the trend variables, an operating state of the electrical apparatus is determined. The possible operating states correspond to specific and distinguishable non-fault and fault scenarios for the electrical apparatus.

Abstract: A method for deriving at least one operating parameter of a fluid-insulated electrical apparatus, in particular of gas-insulated switchgear. The operating parameter is dependent on a dielectric breakdown strength of an insulation fluid of the electrical apparatus. The insulation fluid includes at least three components that are assigned to at least a first and a second component group such that at least one component group comprises at least two components. The component groups differ in their weighted average values of the molecular masses of the components in the respective component groups. At least one quantity which is indicative of the concentration of the first component group and of the concentration of the second component group is determined from the insulation fluid, e.g. by measuring one or more measurement variables with one or more sensors. The operating parameter is then derived using the at least one quantity.

Abstract: The interlocking of two or more sections via the insertion of one or more out-of-plane features in one section or combination of sections through a void in one or more a complementary sections can result in a reinforced ceramic matrix composite article upon securing of the sections. The sections can be secured by friction between two tightly matched sections or by the use of a pin, hook, or clamp. The sections can be constructed from one or more CMC laminate sheets. The out-of-plane feature can be a loop or a flange and the void can be an orifice or a matched loop in the complementary sheet. The securing of the sections can result in a CMC article where the delamination between sheets is inhibited.

Abstract: A welded joint between two metal members in which the weld must support a structural load. The abutting faces of the welded members have step portions formed therein, in which the step portions extend beyond the surface of the adjoining welded members. The outer step portion of one member extends beyond an inner step portion of the adjacent member, and a weld is applied on abutting faces of the members and the step portions. The welded joint of this invention is intended to be used for two adjacent rotor discs in a gas turbine engine. But, the weld arrangement of this invention can be used for welding two pipes together, or two adjacent plate members. The weld arrangement of this invention provides for reduced stress distribution along the weld line that acts to increase part life.

Abstract: An acoustic drum has various implementations for tuning, bracing, attachment, and snare strainer. These implementations are combined in differing configurations of the drum system. Certain aspects of some of the implementations are related to aspects of other of the implementations. For instance, a tuning implementation may use a particular attachment implementation, which in turn may use a certain bracing implementation. Because certain bracing implementations are used, a strainer implementation could be also used if the drum was a snare version. The implementations variously combine to affect performance and/or other esthetic qualities of the acoustic drum.

Abstract: High-speed silicon CMOS circuits and high-power AlGaN/GaN amplifiers are integrated on the same wafer. A thin layer of high resistivity silicon is bonded on a substrate. Following the bonding, an AlGaN/GaN structure is grown over the bonded silicon layer. A silicon nitride or a silicon oxide layer is then deposited over the AlGaN/GaN structure. Following this, a thin layer of silicon is bonded to the silicon nitride/silicon oxide layer. An area for the fabrication of AlGaN/GaN devices is defined, and the silicon is etched away from those areas. Following this, CMOS devices are fabricated on the silicon layer and AlGaN/GaN devices fabricated on the AlGaN/GaN surface.
