US Patent:

20120016523, Jan 19, 2012
Filed:

Aug 7, 2009
Appl. No.:

13/258104
Inventors:

Eric Koehler - Cincinnati OH, US
Steve Verdino - Hamilton OH, US
James Klauke - Miamisburg OH, US
Robert Culley - West Chester OH, US
Joseph Sostaric - Danville CA, US
Assignee:

VERIFI LLC - West Chester OH
International Classification:

G05B 21/02
G01F 1/00
G05D 7/06
G06F 19/00
US Classification:

700265, 702 45
Abstract:

Method and system for monitoring slump flow of hydratable cementitious material such as wet concrete in a rotating mixing drum. Whereas prior art methods use a single value of the hydraulic pressure for turning the drum (such as the average value) and correlating with slump values using the vertical drop measurements of the standard slump test (e.g. ASTM C 143-05), the present invention involves analysis of values corresponding to slump flow of concrete samples, preferably having slump flow values of 16-36 inches when measured using standard slump flow tests (e.g., ASTM C1611-05).

US Patent:

20090037026, Feb 5, 2009
Filed:

Aug 5, 2007
Appl. No.:

11/834002
Inventors:

Joseph Howard Sostaric - Cincinnati OH, US
Michael Topputo - Hamilton OH, US
Steve Verdino - Hamilton OH, US
Andrew S. Morrison - Loveland OH, US
Assignee:

RS SOLUTIONS LLC - West Chester OH
International Classification:

G06F 19/00
G05D 11/00
US Classification:

700265
Abstract:

A system for managing a concrete delivery vehicle having a mixing drum and hydraulic drive for rotating the mixing drum, including a rotational sensor configured to sense a rotational speed of the mixing drum, a hydraulic sensor coupled to the hydraulic drive and configured to sense a hydraulic pressure required to turn the mixing drum, a temperature sensor for sensing temperature of the drum, and a communications port configured to communicate a slump calculation to a status system commonly used in the concrete industry, wherein the sensing of the rotational speed of the mixing drum is used to qualify a calculation of current slump based on the hydraulic pressure required to turn the mixing drum. Temperature readings are further used to qualify or evaluate a load. Also, water purge connections facilitate cold weather operation.
