Current GPS sensing technology enables estimation of road
grade and, consequently simple treatment of parameter
estimation from a static mass balance. An on-line recursive
parameter estimation scheme based on this idea has been
developed and demonstrated experimentally with a
passenger vehicle. Both methods for estimating road grade
from GPS produced a rapidly converging mass estimate that
fell within ±2% of the measured [...]
The Engineering of Pt/Carbon Catalyst Preparation
For application on Proton Exchange Fuel Cell Membrane
This paper will deal with the strong electrostatic adsorption (SEA) method
used for catalyst preparation of Platinum on carbon supports for use in proton
exchange fuel cell membranes (PEFCM). The main objective is to optimize
dispersion and loading of Pt on carbon supports. Characterization results, of [...]
TAROL units (Tapered Roller Bearings) are double row tapered roller bearings that are supplied with factory-set clearance, greased and sealed. The TAROL units are thus supplied ready-to-fit and are pressed onto the shaft journal by means of a hydraulic unit.

Air pressure (psig or bars) at motor location.
2. Pipe size of air supply system to assure adequate
volume (cfm or m3/min) so as to minimize line loss
(air pressure drop during motor operation).
3. Plant air system pressure may vary during the day
due to use by other equipment; therefore, base the
selection of the air motor on the lowest [...]
This paper deals with the energy audit analysis of a dry type rotary kiln system working in a cement plant in Turkey. The kiln has a capacity of 600 ton-clinker
per day. It was found that about 40% of the total input energy was being lost through hot flue gas (19.15%),cooler stack (5.61%) and kiln shell [...]
In a recent consulting assignment we realized that there was some lack of understanding of the whole system of project cost control, how it is setup and applied. So we decided to write up a description of how it works. Project cost control is not that difficult to follow in theor

commonly used gas (argon) is protecting
the weld buddle from airborne contaminants
TIG (Tungsten Inert Gas) produce a precise

Welds more metals than any other process
Shielding gas protects the weld and tungsten
Produces high quality, clean welds
TIG welding uses a non-consumable tungsten

Pumping water for irrigation is the larg-est use of on-farm agricultural energy in California.
Growers are fully aware of the need for increasing overall efficiency of their pumping plant (pump and motor combination), but they do not always know how to achieve it.
This Application Note describes some specific measures.
