Abstract: A modular air vent assembly kit can be used to cover duct openings that supply a flow of heated or cooled air to a room in addition to covering duct openings that receive return air from a room. The modular air vent assembly kit is comprised of a base, a damper mechanism, and two different faceplates where the damper mechanism can be selectively assembled into the base depending on whether control through the air vent by operation of a damper is needed in the particular duct opening and where either of the two faceplates may be selectively connected with the base where one faceplate has a lattice and is used in combination with the damping mechanism and the other faceplate has a series of louvers and is used when the damping mechanism is not used in the vent assembly.

Abstract: A noise dampening shroud is configured to surround the generator of lithotriptor device to reduce the noise emissions caused as a result of the generation of acoustic shock waves during extracorporeal treatment of a patient. The shroud comprises an insulating body and a cover. The insulating body comprises sound dampening insulation and is configured to surround substantially all of the housing that typically encases the generator of convention lithotriptors. The cover is comprised of a thin pliant material configured to surround the insulating body and is provided with fasteners for removably securing the insulating body to the generator. When attached to the generator of a lithotriptor device, the shroud greatly reduces the noise emitting by the generation of acoustic shock waves and thereby minimizes the distraction and disturbance caused by such noise.

Abstract: A mounting bracket for an electric switch is constructed of a single metal piece and does not require separate fasteners for holding the electric switch on the bracket.

Abstract: In a device wherein a rotary shaft is provided in a pipe through which a fluid is passed, a butterfly valve is installed in the pipe, an actuator and an angle sensor are directly arranged on the outer end of the pipe of the rotary shaft, and angle control for adjusting an angle detection signal to a command value is performed to thereby adjust an amount of a fluid passing through the pipe. An actuator includes a rotor composed of a permanent magnet rotatably supported by the rotary shaft and has two magnetic poles, namely, N and S poles, and a stator composed of a winding wrapped around a cylindrical core formed of a soft magnetic member.

Abstract: A hydraulic fluid circuit for a quick rise type lifting jack positions multiple valves that control two stages of the lifting operation of the jack in the same valve housing machined into a base of the jack and thereby reduces the costs involved in manufacturing and assembling the hydraulic circuit of the jack.

Abstract: An arm-driven sleeve valve utilizes a single pin connection to transmit torque from a shaft of the sleeve valve to a pair of arm portions suspended therefrom for controlling the flow of fluid from the valve by axially moving a gate. The single pin connection is centrally positioned between the arm portions and ensures the each of the arm portions exerts an equal force on the gate, regardless of torsional deflection of the shaft. Use of the invention allows arm-driven sleeve valves to be driven asymmetrically from only one of opposite axial ends of the shaft without tending to bind the gate against the main body of the valve.

Abstract: A furnace includes a motor in a motor housing that drives a fan that draws heated air through a heat exchanger of the furnace and also draws a flow of air through the motor housing to cool the motor as well as the motor housing.

Abstract: The invention relates to the discovery of a novel RNA sequence at the 3′ terminal sequence of hepatitis C virus (HCV) genome RNA. Included in the invention are the 3′ sequence, its complement, and their use for nucleic-acid based diagnostics and for developing and evaluating novel anti-HCV therapies. This sequence element, which is conserved among HCV genotypes, is likely to be essential for viral replication, and required for construction of full-length HCV cDNA clones capable of yielding infectious RNA, progeny virus or replication-competent HCV replicons. Such functional clones are useful tools for evaluation of therapeutic approaches and as substrates for developing candidate attenuated or inactivated HCV derivatives for vaccination against HCV.

Abstract: The present invention relates to a method of producing nanophase WC/TiC/Co composite powder by means of a mechano-chemical process comprising a combination of mechanical and chemical methods. For this purpose, the present invention provides a method of producing nanophase WC/TiC/Co composite powder, said method comprising as follows: a process of producing an initial powder by means of spray-drying from water-soluble salts containing W, Ti, and Co; a process of heating to remove the salts and moisture contained in the initial powder after spray-drying; a process of mechanically ball-milling to grind oxide powder after removing the salts and moisture therefrom, and to homogeneously mix the powder with an addition of carbon; and a process of heating the powder after milling, for reduction and carburization, in an atmosphere of reductive gas or non-oxidative gas.

Abstract: Apparatus for inserting a corner member into channel-shaped flanges of a duct. The corner member has first and second legs. The duct includes longitudinally extending duct panels. The channel-shaped flanges of the duct extend laterally from at least one end of the duct panels. The apparatus a corner member support mechanism adapted for supporting the corner member, a duct moving mechanism, and a pressing mechanism. The duct moving mechanism has a duct pusher moveable between a first position and a second position. The duct pusher imparts a moving force against the duct upon movement of the duct pusher from its first position to its second position.

Abstract: A partitioned container assembly for separating articles to be packaged in a container in a manner that facilitates ventilation of the compartments. The assembly includes one or more divider partitions configured to form an asymmetrical pattern of compartments and specially adapted separating sheets positioned between stacked divider partitions and aligned therewith to improve ventilation between layers of divider partitions without sacrificing functionality.

Abstract: A partition assembly is used in a container to divide the container into separate compartments and also as a display for the contents of the container. The partition assembly is comprised of at least one panel that is dimensioned to fit inside and divide the container into separate compartments. The at least one panel has indicia thereon and is adapted to be removed from the container and attached to the top edge of a wall of the container to display the indicia above the container.

Abstract: A foldable garment hanger has shoulder support members that can be folded together while supporting a garment thereon. The foldable hanger allows the garment to be quickly folded in half about the centerline of the backside of the garment where the garment can then be folded horizontally one or more times so as to fit into a conventional carry-on baggage. The foldable hanger is further provided with a hook configured such that a traveler can unpack and unfold the garment by simply hanging the foldable hanger on a conventional hanger rod or hook and unfolding the shoulder support members of the invention. When unfolded, the invention can be used in a manner similar to a conventional garment hanger.
