摘要:
A screen assembly for installation in a fenestration product of the type having a window covering with a sliding operator. The screen assembly includes a screen frame having a screen material and is adapted to releasably attach to an interior side of the fenestration product. The screen assembly includes a screen operator slidable relative to the screen frame and releasably engagable with the sliding operator, such that the screen operator is operable from the interior side of the screen assembly.

The present invention relates to a means for isolating a fan drive means within a chamber from the fan driven fluid. An enclosure is provided which isolates the fan drive means from the driven fluid. The enclosure having multiple opening to the exterior of the chamber and allowing naturally occurring convection to help maintain ambient conditions around the fan drive means.
摘要:
An air dryer having an internal orifice designed into an outlet end cap that eliminates the need for external valves or regulators to control the flow of air through the dryer. The internal orifice, which can be press-fit or threaded into the end cap, provides a consistent and stable outlet flow and dew point and eliminates the need for instruments to measure outlet flow and dew point. The orifice size can be easily changed for changing outlet flow and dew point. A protective tubular shroud is provided for shielding a membrane module of the dryer, and for routing sweep gas to a bottom vent.

A fenestration product having a covering, such as a blind or shade, mounted between panes of viewing material or glass. The fenestration product including a sliding operator coupled to the covering for adjustment of the extension and contraction of the covering across a viewing area of the fenestration product. The sliding operator configured adjust tilt of tiltable components of the covering, such as blind slats, in a single operation with the extension or contraction of the covering. The fenestration product may include a removable viewing panel, such as a double glazing panel, with the sliding operator built into or mounted on the panel. The fenestration product also including an actuation system coupled to the sliding operator for controlling adjustment of extension and contraction and/or tilt of the covering. An insect screen having a sliding operator engageable with the sliding operator of the panel may also be provided.

An automated handling apparatus for testing and labeling a printed circuit board. The apparatus comprises a housing having at least one tray exchanger assembly attached thereto. Disposed on the tray exchanger assembly is a cassette tray which accommodates at least one circuit board, and is selectively movable between first and second positions by the tray exchanger assembly. Also attached to the housing is a testing assembly for conducting a desired testing protocol upon the circuit board, a labeler assembly for applying a label to the circuit board subsequent to the completion of the testing protocol, and a loader assembly for selectively transporting the circuit board between the tray exchanger, testing, and labeling assemblies.

A geartooth sensor is provided with a carrier shaped to form a cavity in which semiconductor chips can be disposed. The carrier partially encapsulates a permanent magnet and a lead assembly. Unencapsulated portions of the lead assembly are exposed within the cavity to permit semiconductor components to be attached to a portion of the lead assembly. A cover is attached to the carrier to seal the cavity and protect the magnetically sensitive components located therein. The carrier, with its associated lead assembly and permanent magnet, can then be attached to a printed circuit board and a support structure to form a geartooth sensor. A protective enclosure can be disposed over the sensitive components of the geartooth sensor.

A circuit board handling and testing apparatus comprising a housing which defines a top surface. Attached to the housing is a magazine assembly which accommodates a plurality of circuit boards and is adapted to dispense the circuit boards onto a testing assembly attached to the housing one at a time. Each of the circuit boards stored within the magazine assembly defines a longitudinal axis. The testing assembly includes a modular testing component for receiving the circuit board dispensed onto the testing assembly and performing a testing protocol thereon. A reciprocal transport assembly attached to the housing pushes the circuit board dispensed onto the testing assembly laterally relative to its longitudinal axis into the modular testing component of the testing assembly. A sorting assembly which is also attached to the housing selectively directs the tested circuit board into a particular containment vessel based upon the outcome of the testing protocol. The testing assembly is adapted to eject the circuit board into the sorting assembly subsequent to the completion of the testing protocol, with the modular testing component being selectively removable from the testing assembly and replaceable with an alternative modular testing component.

A needleless injection device includes an initiator valve controlling flow of compressed gas into a reservoir. A poppet valve connecting to the reservoir has a gas pressure regulation end to regulate flow from the initiator valve into the reservoir. A clamp piston is driven forward by gas pressure from the reservoir and causes jaws to clamp onto a plunger extending into an ampule. The poppet valve opens when reservoir pressure reaches the cracking pressure of the poppet valve. Gas from the reservoir rushes through the poppet valve into a drive chamber and forces a drive piston, containing the clamp piston and jaws, forward causing the plunger to slide into the ampule. A jet of injectant is discharged from the nozzle of the ampule and penetrates through the patient's skin. An improved method of needleless injection uses a specific pressure profile, ampule nozzle diameter, patient, injection site, and injectant parameters.
