Bushing bearings are used as a cost effective alternative to much more expensive ball or roller bearings. The main drawback, however, is the radial clearance between the bearing and the shaft that continues to increase as the bearing wears. In addition to the noise generated, especially in a reciprocating motion application,
In most gear drives, due to inertial motion the driven output shaft becomes the driving one and the driving input shaft becomes the driven one. This condition is known as back-driving. In order to prevent this condition, different types of brake or clutch devices are used. However,
Many alloys have rare earth additions to improve their surface properties at high temperatures. A new product, Minimox® Nanocrystalline Alloy Treatment, exploits this fact to protect a variety of alloys in extreme environmental conditions of elevated temperature and/or corrosive atmospheres.
Steam Generating Apparatus (SGA) is a small, compact hot water or steam generator using a small motor to spin up to speed for whatever you require.
The SGA device is only 4" in diameter using an AC drive to control a 1HP motor. The system would include a micro processor to set up and tweak your specific application.
Simultaneous Production of Nano Carbon, Hydrogen and Energy
ABSTRACT:
This process is based on compression of acetylene. When acetylene is compressed it explodes, generating thermal and mechanical energy and decomposes to its original constituents; carbon (finely divided) and hydrogen.
PROJECT NARRATIVE:
The scope of work includes full process and mechanical design for a system that can produce nano carbon,
This telescope design consists of a primary mirror shaped to a parabola along a single axis. Whereas a conventional telescope focuses light to a single point, the Single-Axis Telescope spreads its focus along a sensor the same width as the mirror.
I call this a scanning telescope because it is designed to be stationary,
Chemical classification is an important operation for many industries. Typically, this is done with portable spectrometers that cost on the order of $5000. The data from portable spectrometers must be transported back to the lab to have post processing determine what the contents of the measurement were. The complexity of these spectrometers is often excessive;
The need to clean up space debris is urgent. We propose a comprehensive, self-sufficient and robotically enabled system, avoiding multiple launch support platforms once deployed. The main outlines comprise an initial vehicle together with a related debris processing plant.
Start up of energy equipment is guided by some restrictions of acceptable temperature changes with the aim to avoid higher stress conditions in construction materials.
These restrictions lie in a range of several [K/minute] to avoid higher stresses in construction during start up processes.
If these loadings, temperature changes in working fluid or steam in steam boilers and turbines,

Introduction:
Nuclear power plant emergency cooling systems serve the essential purpose of providing cooling for the reactor core in the event of failure of normal cooling systems.
