Filed:

Oct 28, 2010

Appl. No.:

12/914126

Inventors:

David Stanley Hawkins - Colorado Springs CO, US
Carl Robert Perkins - Colorado Springs CO, US
Gregory Scott Sprenger - Evergreen CO, US

Assignee:

Velcon Filters, LLC - Colorado Springs CO

International Classification:

B01D 35/30
B01D 35/00
B01D 35/28
B01D 29/13

US Classification:

210437, 210232, 210435, 210457

Abstract:

A separator cartridge includes a support tube formed of a perforated strip of metal configured to normally have a first diameter and a spaced array of hexagonal apertures formed therein and a substantially cylindrical screen member having a diameter less than the first diameter of the support tube, wherein a diameter of the support tube is decreased from the first diameter to a diameter less than the diameter of the screen member to be received in the screen member, and wherein the support tube causes the screen member to be maintained in a substantially taut manner.

Filed:

Mar 6, 2007

Appl. No.:

11/682605

Inventors:

Gregory Scott Sprenger - Colorado Springs CO, US
David Stanley Hawkins - Colorado Springs CO, US
Michael Joseph Gish - Colorado Springs CO, US
Jed Babbington Stevens - Colorado Springs CO, US

International Classification:

C02F 1/00

US Classification:

210746

Abstract:

A filter monitor is disclosed capable of sensing the presence of water in the filter. The sensor utilizes changes in capacitance of a water absorbing media which functions as a dielectric disposed between a pair of electrodes. The sensor is in communication with a valve means to interrupt the transient fluid when a predetermined amount of water is present in the fluid.

- Cleveland OH, US
DAVID STANLEY HAWKINS - COLORADO SPRINGS CO, US

International Classification:

B01D 17/04
B01D 39/16
B01D 39/20
B01D 39/18

Abstract:

According to one aspect of the invention, a coalescer cartridge for separating a first fluid from a second fluid includes a pleated filter media portion including a pleated fluid separation layer configured to separate a first fluid from a second fluid, the first fluid forming relatively small droplets of fluid suspended in the second fluid; and a wrap filter media portion downstream of the pleated media portion including a droplet growth layer configured to coalesce the relatively small droplets of the first fluid into relatively larger droplets of the first fluid.

International Classification:

G06F 17/30
G06F 3/06

Abstract:

Techniques provide for hardware accelerated data movement between main memory and an on-chip data movement system that comprises multiple core processors that operate on the tabular data. The tabular data is moved to or from the scratch pad memories of the core processors. While the data is in-flight, the data may be manipulated by data manipulation operations. The data movement system includes multiple data movement engines, each dedicated to moving and transforming tabular data from main memory data to a subset of the core processors. Each data movement engine is coupled to an internal memory that stores data (e.g. a bit vector) that dictates how data manipulation operations are performed on tabular data moved from a main memory to the memories of a core processor, or to and from other memories. The internal memory of each data movement engine is private to the data movement engine. Tabular data is efficiently copied between internal memories of the data movement system via a copy ring that is coupled to the internal memories of the data movement system and/or is coupled to a data movement engine. Also, a data movement engine internally broadcasts data to other data movement engines, which then transfer the data to respective core processors. Partitioning may also be performed by the hardware of the data movement system. Techniques are used to partition data “in flight”. The data movement system also generates a column of row identifiers (RIDs). A row identifier is a number treated as identifying a row or element's position within a column. Row identifiers each identifying a row in column are also generated.
