The application of microprocessor technology has long been expected to move out of the automotive world into heavy-duty engines and equipment, and now the first results of that technology are beginning to be felt in the industrial engine-powered equipment world."With electrically driven accessories, we have the ability to provide only the flow, pressure or power required to match actual operating conditions. By continuously adjusting to different operating modes, there are a number of control features and opportunities available," said David Orr, commercial manager of Caterpillar Inc.''s More Electric Initiative Program.

Air supplyAir systems on a light-rescue truck should be given careful consideration due to the substantial weight of most of the components. Air system storage choices should be matched to the output of the stationary air compressor. DOT cylinders with 4,500 or 6,000psi ratings weigh 144 pounds or 188 pounds each while ASME cylinders with 5,000 or 6,000psi ratings that weigh 400 pounds each.The DOT cylinders need easy access for removal, as they will need to be removed every five years for hydro testing. The ASME cylinders never need hydro testing, so they can be located in areas where future access may not be of a concern. However, they cost more than DOT cylinders.

Now that I''m getting comfortable with aspects of farming that I''ve learned the hard way, I can take on Horses, Mules, and Ponies, an arena where I have never ventured. The comprehensive knowledge from pre-Civil War America in regards to horse care is much more practiced and detailed than anything that could be written today. This remains one of the bibles of horse breeding, care, and riding. Particularly interesting to me was "How to Physic a Horse--Simple Remedies for Simple Ailments," which drew heavily on the principles of homeopathy in diagnosis and treatment. --David Guyer-Stevens"The importance of having the correct amount of suck in the share cannot be emphasized too strongly. Too little underpoint suction will cause the plow to "ride out" of the ground and cut a furrow of uneven depth. Too much will cause "bobbing" and heavy draft. In both cases, the plow is difficult to handle. If the landslide suction is too great, the bottom tends to cut a wider furrow than can be handled properly, and the reverse is true when the landslide suction is not sufficient. --THE OPERATION, CARE, AND REPAIR OF FARM MACHINERY "A warm dry pen is necessary for the health and comfort of the pig. Cold and damp induce more diseases than are charged to these causes.... But the difficulty is to have a door that will shut of itself and can be opened by the animals whenever they desire. The engraving [below] shows a door of this kind that can be applied to any pen, at least to any to which a door can be affixed at all. It is hung on hooks and staples to the lintel of the doorway, and swinging either way allows the inmates of the pen to go out or in, as they please. --BARNS AND OUTBUILDINGS AND HOW TO BUILD THEM
