Desiccant bag with integrated filter and method of making same

The present invention relates generally to desiccant bags and filters for use in receiver/dryers or accumulator canisters of automotive air conditioning systems. More specifically, the present invention relates to a dual or single desiccant bag provided with a filter section such that the desiccant bag effectively combines two separate components, a desiccant bag and a filter, into a single article. Accordingly, the bag is adapted to contain adsorbent material therein to adsorb moisture, or undesirable substances, within the a/c systems of automobiles, trucks or other motor vehicles while the filter is adapted to keep particles, dirt, or dust from entering the orifice in the bight of a U-bend tube where oil pickup is provided for lubrication of the a/c system.

Desiccant feeder system and apparatus

A desiccant feeder system comprising, a reservoir for desiccant canisters, means for delivering the canisters through a transfer tube to at a loading station, means for presenting the open end of containers one at a time at the loading station, means for circulating air at high velocity through the tubing including an adjustable internal ring-shaped nozzle to deliver desiccant canisters from the reservoir to the loading station, and a shuttle selectively actuatable to discharge at least one desiccant cannister to the containers at the loading station.

Display device with desiccant coating

In a display device which is formed by attaching together a device substrate and a sealing substrate, a desiccant is coated to form a shape having a plurality of bending portions on the sealing substrate. Furthermore, the path coated with the desiccant on the sealing substrate is longer than conventional devices, thereby increasing a gross surface area and thus improving moisture absorption effect.

Spin-on desiccant cartridge with integral oil removal filter

An air dryer assembly for removing moisture and oil from a compressed air system includes a desiccant material received in a shell for adsorbing moisture as compressed air passes therethrough. A coalescing element is disposed between an inlet and outlet for removing oil aerosols from the compressed air. A check valve is disposed in parallel with the coalescing element and forces the compressed air to pass through the coalescing element as air flows from the inlet to the outlet. During a purge or reverse flow, compressed air bypasses the coalescing element and removes oil collected in the cartridge through the inlet.
