Abstract: Various technologies pertaining to causing fluid in a supercritical Brayton cycle power generation system to flow in a desired direction at cold startup of the system are described herein. A sensor is positioned at an inlet of a turbine, wherein the sensor is configured to output sensed temperatures of fluid at the inlet of the turbine. If the sensed temperature surpasses a predefined threshold, at least one operating parameter of the power generation system is altered.

Abstract: Disclosed illustrative embodiments include modular power infrastructure networks, distributed electrical power infrastructure networks, methods for operating a modular power infrastructure network, and methods for fabricating a modular power infrastructure network.

Abstract: A seal assembly for sealing a machine with a first chamber and a second chamber is provided. A rotating shaft extends through the first and second chambers, and rotates therein. The seal assembly has a seal housing, a seal ring and a seal pin. The seal housing is positionable in the machine housing. The seal housing has a seal pocket extending into a fluid side thereof, and a housing receptacle extending into an inner diameter thereof at the seal pocket. The seal ring is positionable in the seal pocket of the seal housing for forming a seal therewith. The seal ring has a ring receptacle extending into an outer diameter thereof. The ring receptacle is positionable adjacent to the housing receptacle for defining a pin hole therebetween. The seal pin is loosely positionable in the pin hole whereby movement about the seal ring is accommodated while preventing rotation thereof.

Abstract: Techniques for generating power are provided. Such techniques involve a thermodynamic system including a housing, a turbine positioned in a turbine cavity of the housing, a compressor positioned in a compressor cavity of the housing, and an alternator positioned in a rotor cavity between the turbine and compressor cavities. The compressor has a high-pressure face facing an inlet of the compressor cavity and a low-pressure face on an opposite side thereof. The alternator has a rotor shaft operatively connected to the turbine and compressor, and is supported in the housing by bearings. Ridges extending from the low-pressure face of the compressor may be provided for balancing thrust across the compressor. Seals may be positioned about the alternator for selectively leaking fluid into the rotor cavity to reduce the temperature therein.

Abstract: A powered appliance includes a working member, a handle operably coupled to the working member and a control movable between a first position proximate the handle in which movement of the working member is permitted and a second position distant the handle in which movement of the working member is at least reduced. One of the handle and the control is configured to at least partially receive the other of the handle and the control when in the first position. At least one of the handle and the control includes a flexible member adjacent the other of the handle and the control.

Abstract: Integrated flywheel uninteruptible power supply (UPS) systems provide reliable back-up power protection in a single integrated housing unit. The integration of the two normally independent systems results in a synergism such that various components may be shared between the systems. For example, the flywheel unit and the UPS electronics unit may utilize a single cooling system that is less complex and requires less energy to operate than two independent cooling systems. Other shared components may include at least control circuitry, user and display interface circuitry, fusing, DC bus capacitors, and emergency shut-off circuitry.

Abstract: Apparatus for measuring contamination in a hot melt flow. The apparatus includes a flow cell tube adapted to pass the melt flow. Apparatus is provided for directing laser energy through the tube and the melt flow passing through the flow cell tube to a laser energy detector producing an electrical signal representative of the size of a contaminant in the flow melt. A heater is provided for heating the melt flow as such melt flow passes through the flow cell tube. The apparatus is adapted to measure contamination in a hot melt where the temperature of the melt must be maintained as the melt passes through the flow tube. The flow tube, laser, detector and heater are disposed within a housing. The housing has a cooling chamber. The detector is disposed in the cooling chamber to thermally isolate the detector from the heating of the flow.

Abstract: Concentrated, structured liquid detergent compositions in the form of lamellar surfactant droplets dispersed in an aqueous electrolytic continuous phase comprises a mixture of:a) from about 10 to 45% by weight of surfactant;b) at least one detergent builder;c) from about 0.01 to about 5% by weight of a deflocculating polymer composition containing polymer chains of the structure P-QR, wherein P represents a polymer chain segment of a hydrophilic polymer, and QR represents a hydrophobic end-cap group wherein R is an organic hydrophobic radical containing from about 4 to 28 carbon atoms, and Q is selected from the group consisting of O, S, SO, SO.sub.

Abstract: Apparatus for resurfacing vehicle brake discs by machining opposite sides of the brake disc by a pair of tools and in which the tools can be moved by a lead screw and including a motor which is coupled to the lead screw by a belt for driving it and including means for decoupling the motor to the lead screw including means for loosening the belt so it will not drive the lead screw.

Abstract: A fixture and method for simultaneously resurfacing opposite sides of a vehicle disc brake without removing the disc from the vehicle. The wheel of the vehicle and the hydraulic caliper for the disc are removed and the disc is then rotatably driven while opposite sides of the disc are resurfaced. A resurfacing tool fixture is removably mounted directly on the vehicle, for instance on the caliper mount bracket adjacent the disc, and the fixture has a shiftable frame having a pair of opposed carbide tipped tools which engage opposite sides of the disc and which are moved across the entire surface of the disc for complete resurfacing thereof, all without removing the disc from the mounting in the vehicle.
