A variable pressure reducing device for reducing high pressure in steam and hot water samples forces the liquid through an annular passageway between a pair of rods within a complementary pair of tubes. The flow rate through the rod-in-tube device, or the pressure drop across the device, is adjustable by means of a rotatable guide screw for adjusting the position of the rods within the tubes. The rods are tapered to provide a smooth flow of liquid through the device. The seal around the guide screw is self energized by means of a seal jacket between a valve gland and a stem portion of the guide screw constructed so that the biasing force of a spring on the seal jacket is supplemented by pressure from liquid flowing through the device. The guide screw is centered within the valve gland to keep the guide screw properly aligned, particularly when the device is used with a motor for rotating the guide screw to adjust the position of the rods.

The present invention provides a power converter mounting system including a flange that cooperates with a power converter and an enclosure. The flange includes a through hole that cooperates with an opening in the enclosure to permit the power converter to extend therethrough. A number of fasteners connect to the flange and overhang a portion of the power converter. The fasteners are configured to be manipulated from a front side of the power converter. An outer perimeter of the flange extends beyond the opening in the enclosure. The flange is secured to the enclosure with a number of fasteners that are also operable from the front side of the power converter. The power converter mounting assembly is configured to secure a power converter to an enclosure so as to satisfy a variety of sealing requirements as well as allowing convenient servicing of the power converter system.

A technique is disclosed for cooling resistive elements, such as brake resistors used in motor drives, as well as other resistors. A phase change heat spreader is thermally coupled to the resistive element and a continuous phase change cycle takes place in the heat spreader to extract heat from the resistive element. The element and heat spreader may be packaged as a modular unit or may be integrated into a system.

AC pre-charging techniques are provided for pre-charging the DC bus on a motor drive. AC pre-charging techniques involve pre-charge circuitry including a manual switch, an automatic switch, and pre-charge control circuitry to switch the automatic switch between pre-charge and pre-charge bypass modes in response to an initialized pre-charge operation, input voltage sags, etc. In some embodiments, the pre-charge operation may be initialized by switching the manual switch closed. In some embodiments, the pre-charge operation may also be initialized by a detected voltage sag on the DC bus. The pre-charge circuitry may also be configured to disconnect a motor drive from the AC power supply under certain fault conditions.

A technique for cooling electrical bus structures is disclosed, in which a phase change heat spreader is thermally coupled to the bus. A continuous phase change cycle occurs within the heat spreader to draw heat from the bus during operation. The heat spreader may be planar, and extend over an area greater then the surface area of the bus to enhance cooling and to render the overall assembly more isothermal. The heat spreader may be placed near bus joints and circuits to remove heat caused by increased resistance at such locations.
