US Patent:

6351714, Feb 26, 2002
Filed:

Mar 3, 1998
Appl. No.:

09/033682
Inventors:

John R. Birchmeier - Columbus OH
Assignee:

Entek IRD International Corporation - Milford OH
International Classification:

G01M 700
US Classification:

702 56, 702145, 73570, 73660
Abstract:

A hand-held data collection and analyzing unit for collecting and analyzing vibration data induced by a rotating shaft including a processor that first converts the analog vibration signal into corresponding digital vibration samples. Thereafter, the processor provides in response to the digital vibration samples, corresponding output vibration samples in which samples within each set of output vibration samples are provided at a rate that varies as a function of variations in the speed of the rotating shaft. A digital processor then collects a time waveform record in response to a plurality of the output vibration samples, wherein the sample rate for the output vibration samples collected in the time waveform record varies as a function of variations in the speed of the rotating shaft.

Method And Apparatus For Measuring The Polarized Potential Of A Buried Or Submerged Structure Protected By Impressed Current

US Patent:

45917922, May 27, 1986
Filed:

Feb 8, 1984
Appl. No.:

6/578069
Inventors:

John R. Birchmeier - Columbus OH
George T. Ruck - Worthington OH
Neil G. Thompson - Dublin OH
Thomas J. Barlo - Columbus OH
Assignee:

Gas Research Institute - Chicago IL
International Classification:

G01N 2700
US Classification:

324425
Abstract:

The polarized potential at the boundary between a submerged pipe and a medium is measured unaffected by the presence of a distributed IR drop in the medium due to an impressed current from a corrosion protection system. The voltage between the pipe and a reference electrode in the medium is measured when the protection system current is zero. This is accomplished with a sample-and-hold circuit controlled by a trigger signal derived from the input signal and having a variable phase for controlling the phase angle at which the sample is taken.

US Patent:

20210321545, Oct 14, 2021
Filed:

Apr 8, 2021
Appl. No.:

17/226042
Inventors:

- Columbus OH, US
John R. Birchmeier - Ashley OH, US
Jack A. Moreno - Delaware OH, US
International Classification:

H05K 7/20
Abstract:

A cooling system can include a two-stage compressor, a variable speed fan and a controller for continuously modulating cooling capacity of the system. The compressor can run in a loaded state and the fan can run at a first speed when a call for cooling calls for maximum system cooling capacity. The compressor can run in the loaded state and the fan speed can decrease to a second fan speed as the called for cooling capacity decreases. The compressor can run in an unloaded state and the fan speed can be increased. The compressor can run in the unloaded state and the fan speed can decrease to a third fan speed as the called for cooling capacity decreases.

US Patent:

20170276417, Sep 28, 2017
Filed:

Sep 27, 2016
Appl. No.:

15/277569
Inventors:

- Columbus OH, US
Daniel J. SCHUTTE - Lewis Center OH, US
Matthew RAVEN - Columbus OH, US
John BIRCHMEIER - Ashley OH, US
International Classification:

F25B 49/02
F25B 31/00
Abstract:

The present disclosure relates to a method for controlling a level of superheat during a pump mode of operation of a refrigeration system, wherein the refrigeration system can operate in either the pump mode or a compressor mode, and has an electronically controlled expansion valve (EEV). A controller obtains a stored, predetermined pump differential pressure range able to be produced by a pump of the system. The controller also obtains a stored, predetermined superheat range, and detects a superheat level. When the detected superheat level is outside of the superheat temperature range, the controller commands adjusting at least one of the EEV and a speed of the pump based on whether the detected superheat level is above or below the superheat range, and whether a current pump differential pressure is above or below the predetermined pump differential pressure range.
