US Classification:

428/220000, 442/340000, 442/345000, 442/381000, 442/389000, 156/166000, 156/180000, 156/181000

Abstract:

Improved filtration media or filter bodies can be made from fine fiber and can be formed into a filtration structure having no internal defects. The filter media or filter body comprises a collection of spot in fiber with defined fiber diameter, layer thickness and media solidity. The fine fiber is formed into a media body and obtains substantial flux and filtration efficiency. The filtration media or body can comprise single or multiple layers of fine fiber combined into the improved filter body.

Appl. No.:

6/189242

Inventors:

James R. Schaefer - North Palm Beach FL
Leland J. Radtke - North Palm Beach FL

Assignee:

United Technologies Corporation - Hartford CT

International Classification:

F16D 1374

US Classification:

192113B

Abstract:

The present invention provides apparatus for precisely distributing a liquid coolant or lubricant about the interior of a rotary machine. Distribution in known quantity is sought over a wide range of shaft speeds. In one embodiment the apparatus of the invention is employed to distribute oil in various quantities to bearings and splines within a clutch assembly. Lubricating oil is sprayed from a stationary nozzle into the interior of a rotating shaft. An insert at the interior of the shaft has a plurality of longitudinal splits which intercept and collect the oil in proximity to orifices in communication with bearings and splines to which oil distribution is desired.
