Abstract: There is provided a method and apparatus for an improved ultraviolet lamp assembly using an ultraviolet (UV) lamp with a sleeve having improved UV lamp temperature characteristics for improved UV lamp intensity output and germicidal affect. The ultraviolet lamp assembly comprises a UV lamp housed in a vented open end quartz sleeve in a portable air conditioning (AC) unit. The quartz sleeve comprises a distal sleeve open end and a proximal base open end through which a UV lamp is secured to the sleeve and AC unit. The proximal open end of the quartz sleeve comprises a plurality of venting slots that allow ambient air to travel into and out of the space between the UV lamp and the sleeve wall. Operation of the AC unit fan results in air flow into the sleeve at a proximal sleeve base end and out through the distal open end of the sleeve to thereby maintain the UV lamp at a desired temperature for improved germicidal affect.

Abstract: The present invention discloses a motorized drive unit for operating a valve including a gear, a motor, a chain coupling the gear and motor, a housing encasing the motor, gear, and chain, and a rotation limiting piece. Additionally, the present invention discloses a method for mounting a gear to a gate valve handle by providing a gear and a mounting plate, positioning the mounting plate beneath the handle of the gate valve, positioning the gear above the handle of the gate valve, and coupling the mounting plate to the gear. Further, the present invention discloses a method for mounting a gear to a ball valve by providing a gear having a cutout portion, removing the handle from the ball valve stem, placing the second portion of the handle through the cutout portion of the gear, and coupling the handle and the gear to the stem.

Abstract: An air intake assembly for a combustion oil burner, the assembly comprises a housing having a front wall, a back wall and a peripheral side wall between the front wall and the back wall, the housing defining an air intake chamber therein, the front wall having a partly circular air intake hole therein, an axle mounted to the housing between the front and the back walls, first, second and third rotatable vanes rotatably mounted to the axle and positioned adjacent to the air intake hole, the first rotatable vane is fixedly attached to the axle, and a mechanism mounted on the rotatable vanes for sequentially rotating the rotatable vanes whereby the air intake hole can be selectively opened from 0.degree. open where substantially no air can pass through the hole and into the air intake chamber, to approximately 270.degree. open where air can flow into the chamber.

Abstract: A flow control has a rotary gate residing within an internal flow space in a conduit. The gate is mounted for movement relative to the conduit between first and second positions, the gate in the first and second positions accounting for a different flow rate between first and second fluid masses between which the gate resides. The gate has an actuator with a plurality of spaced shoulders. A flexible force-applying member is connected to the actuator and bears upon the shoulders to thereby urge the gate towards the other of the first and second positions. The shoulders are situated so that the number of shoulders engaged by the force-applying member at any one time is not the same as the gate moves from the one of the first and second positions towards the other of the first and second positions.

Abstract: A draft inducer having a pair of arcuate semi-scrolls within a cylindrical housing defined by a circular inner end plate and a circular outer end plate vertically spaced by a sidewall. A metal conduit element is connected concentrically to the inner end plate and an electric motor is connected adjacent the outer end plate. A fan blower wheel is disposed in the housing coaxially with the conduit element and is drivingly connected to the motor. The semi-scrolls define curved air passages with twin, oppositely directed outlets for discharging fluid flow outdoors at rates minimally effected by ambient wind conditions.

Abstract: A power vented direct vent system for a fuel-burning appliance wherein a power venter is associated with a vent pipe to create adequate draft for combustion. Outside air is supplied to the appliance for combustion and also communicates through a regulator with the vent pipe for addition to the flue gases. The draft regulator assures adequate draft and can be a barometric draft control. The power vented direct vent system is directly connected to the fuel-burning appliance with complete isolation of the combustion system from the space in which the appliance is located.

Abstract: A power venter for connection to an appliance vent system to provide draft and gas flow and which has components mounted exteriorly of a building wall and components extending through the wall, with the latter components including an inner pipe connectable to a vent pipe of a vent system and an outer pipe surrounding the inner pipe in spaced relation functioning as a heat shield and providing an annular space therebetween. The outside components include a vent hood with a blower housing mounted interiorly thereof and having a blower with an inlet communicating with an outside end of the inner pipe and having a blower outlet to atmosphere. An orifice plate is associated with the blower to separate positive and negative pressure areas and has an orifice opening leading to an eye of the blower, with the blower rotatable about an axis offset from the longitudinal axis of the inner pipe to provide a desired blower diffuser angle.

Abstract: An in-line power venter insertable into a vent pipe and having a housing attachable to the vent pipe. The housing has separate negative and positive pressure chambers provided by a separator plate positioned within the housing and having an opening for flow of gas to a blower wheel in the positive pressure chamber. The separator plate has a pair of generally semicircular, oppositely-extending sections disposed above the housing for insertion into the vent pipe to positively separate negative and positive pressure zones within the vent pipe. A flow-regulating plate for draft control is mounted within the housing and is manually-adjustable externally of the housing for movement toward and away from an opening in the separator plate to control the flow rate through the opening to the central area of the blower wheel.
