Abstract: An electrical cable connector includes a socket body having two opposite side faces, each of which is formed with a first retaining recess that extends in a longitudinal direction, and a second retaining recess that extends in a transverse direction relative to the longitudinal direction. A cable sleeve extends from a rear end of the socket body, and includes an inner housing and two opposite latch members extending outwardly from two opposite sides of the inner housing. Each of the latch members has a longitudinal portion that is fittingly disposed in a respective one of the first retaining recesses in the side faces, and a transverse portion that extends from the longitudinal portion in the transverse direction and that is fittingly disposed in a respective one of the second retaining recesses in the side faces so as to limit movement of the inner housing relative to the socket body.

Abstract: A fly fishing reel includes a casing having two opposite ends and a peripheral wall extending between and cooperating with the opposite ends to confine an inner space thereamong. A spool is mounted rotatably in the casing and has two opposite flange portions with free ends that are radially and respectively spaced apart from the peripheral wall by first and second gaps. The flange portions divide the inner space into two opposite end chambers and an intermediate chamber which is in fluid communication with the opening and the end chambers via the first and second gaps. A pair of elastic sealing rings are respectively interposed between the free ends of the flange portions and the peripheral wall so as to seal the first and second gaps for preventing dust and liquid from entering into the end chambers via the opening and the intermediate chamber from the exterior of the casing.

Abstract: An apparatus and associated method for discharging a fluid and a liquid separated from the fluid from an outlet chamber of a heat exchanger. The outlet chamber is configured to collect the separated liquid. The outlet chamber is in fluid communication with an outlet opening disposed on an exit surface of the outlet chamber. The apparatus includes a plate that is positionable in the outlet chamber adjacent to the exit surface to form a channel between the plate and the exit surface. The plate is configured to protrude over the outlet tube opening so that the fluid flowing through the outlet chamber and into the outlet opening pulls the liquid collected in the outlet chamber through the channel and out through the outlet opening with the fluid. Because of the plate protruding over the outlet opening, the fluid exiting directly from the outlet chamber through the outlet opening must flow through a decreased area. This decreased area produces the vena contracta effect and creates a low pressure region.

Abstract: This invention increases efficiency of a refrigeration system by maximizing the cooling of the condenser and reducing unnecessary work done by the compressor. In air cooled systems it will also increase the stability of the fans by reducing fan cycling. The fan controller will utilize an algorithm that will consider the following inputs: oil pressure, compressor suction pressure, expansion valve position, compressor loading, last compressor loading change, and current fan stage. The algorithm uses fuzzy logic to characterize the inputs and generates an output that controls the system cooling fans.

Abstract: An electric furnace comprising an integral front panel containing a plurality of louvers. The interior of the furnace contains a flow channel to direct air towards the top of the furnace. At least some of the louvers will direct air into the flow channel. The air is then conditioned and delivered back to the home.

Abstract: A system and associated method for protecting during a shutdown a turbine having a turbine shaft and a compressor driven by the turbine shaft. The system include a first lubrication system, a second lubrication system, and a control system. The first lubrication system is configured to provide lubrication to the compressor. The second lubrication system is configured to provide lubrication to the turbine. The control system monitors the rotation of the turbine shaft in response to a shutdown request and causes the first and second lubrication systems to provide lubrication to the turbine and compressor until and after the turbine shaft stops rotating. The control system causes the first lubrication system to provide lubrication for a first predetermined period of time after the turbine shaft stops rotating. The control system causes the second lubrication system provides lubrication for a second predetermined period of time after the turbine shaft stops rotating.

Abstract: A system and method are provided for controlling a three-phase pulse-width-modulated alternating-current voltage regulator, in order to reduce inrush current when starting, for example, a large three-phase induction motor. The system and method include a set of four-quadrant switches connected in a converter circuit between the input voltage and the output load. By applying certain switching states in a determined sequence based on sensed values of the input voltage at the three lines, the system and method synthesize a three-phase variable magnitude output voltage from the three-phase input voltage of fixed magnitude.

Abstract: A method is provided for implementing a three-phase pulse-width-modulated alternating current voltage regulator including six four-quadrant switches, wherein each four-quadrant switch includes two two-quadrant switches. Three series branches, each series branch including one four-quadrant switch, and three shunt branches, each shunt branch including one four-quadrant switch, are provided. To obtain a desired converter state, the two-quadrant switches in the series and shunt branches are turned on or off in a predetermined sequence.

Abstract: A ventilated air cooled cutting system for a circular saw that produces a thinner kerf than previously achievable. The air cooled cutting system is comprised of a saw blade having a thin blade cutting portion and a thick hub portion. The blade cutting preferably is ground from a plate, while the hub portion remains substantially the thickness of the starting plate material. The thicker hub portion serves as a heat sink to conduct heat away from the thinner blade cutting portion. Cooling holes are provided in the hub portion to provide convection cooling of the hub portion. The thicker hub portion also provides rigidity or stiffness to the blade so that it is better able to withstand torsional forces experienced during the cutting operation. If additional cooling is required, a spacer collar having a series of axial and radial apertures can be fitted to the hub portion to force cooling air through the hub portion in order to enhance cooling.

Abstract: The present invention relates to a cold plate for cooling electronic components comprising a base having a top surface onto which at least one electronic component is to be placed; a cooling well formed in the top of the base and open at the top; a feed channel formed in the base for carrying fluid into the cooling well; a drain channel formed in the base for carrying cooling fluid away from the cooling well; cooling well inlets and outlets formed in the cooling well and in communication with the feed channel and drain channels, respectively. The feed and drain channels are sufficiently large relative to the size and flow characteristics of the well and cooling well inlets and outlets such that when the cooling fluid flows through the device, the pressure drop across the feed channel is substantially less than the pressure drop across the well.

Abstract: The invention is directed towards a furnace comprising a panel and filter assembly. At least two z-shaped brackets and two flanges are used to retain a filter directly behind the front panel of the furnace. This allows for easy removal and installation of filters in the furnace. It further allows for the use of commercially available disposable filters.

An aperture through the center provides access for a tap, and cupholders along the surface permit the device, when placed over the barrel, to serve as a table.

Abstract: A method and apparatus for cleaning conductive and non-conductive bodies using a basic aqueous disodium phosphate and sodium bicarbonate cleaning solution. The outside surfaces of a metallic or non-metallic body are cleaned by spraying or brushing the cleaning solution on to body, or by placing the metallic body in electrical contact with the cleaning solution, an anode and a cathode (either of which may be the body itself) and flowing DC current from the anode to the cathode and thus through the chemical solution, thereby causing the cleaning solution to electrolytically clean the body. The DC current is provided by an inverter power source. The body may be immersed in the electrolytic cleaning solution or the electrolytic cleaning solution may be sprayed onto the body.
