A good friend called to let me know that there was an error in my thinking concerning aerial work platforms. I said "there is an aerial work platform in the field population in North America for every 1200 people, give or take a few." I should have said there''s an vermeerchippershredder aerial work platform in the field population for every 950 people. That will decline this year to one machine for every 850 people, give or take a few. That''s still a lot of work platforms, no matter how you cut it! The 951 backhoe attachment from Great Bend Manufacturing mounts on skid steers from 40 to 100 hp and 55 to 100 hp tractors with Cat. II 3 point and I hitch. The 951 offers 9.7 ft. of digging depth with 4575 lb. of digging force. A tapered console and walk-through deck provide comfort and visibility to the operator and two double-action vermeerchippershredder hydraulic cylinders replace chain links to ensure vermeerchippershredder smooth swing operation, the company said. Attach hydraulic Ho-Pac Model 500 vibratory compactor/driver to mini-excavator, backhoe, or trencher to compact or drive soil in narrow trenches. Base plate measures 12 ins. wide and 27 ins. long. Boasts impulse force of 3,940 lbs. at 2,000 cycles per min. with minimum of 9 to 18 g.p.m. from carrier. Optional swivel-top mounting bracket permits precise positioning without moving carrier. My 22-month-old son is mad for trucks. And not just any trucks -- construction vehicles. Out of the vast variety of images he''s exposed to daily, he has honed in on dump trucks and cranes. How did this happen? My partner, Laura, and I are still trying to figure it out. Neither of us drives a big rig. Riley doesn''t watch TV. He has dolls. He loves flowers and animals. But boy, does he love backhoes.

HYDROGEN GENERATORSGenerators vermeerchippershredder can also make hydrogen using one of two basic technologies: proton-exchange membranes (PEM), and palladium membranes. Hydrogen gas generators vermeerchippershredder are most often used in gas chromatographs and vermeerchippershredder in labs for hydrogenation reactions and engine-emission analysis. PEM systems from Parker produce flows from 90 to 1200 cc/mm of 99.99999% pure hydrogen at pressures from 0 to 100 psig. The Balston H2-500 hydrogen generator uses deionized water and electricity. It produces hydrogen gas through electrolytic dissociation of water via the PEM. The resultant hydrogen stream then passes through a palladium membrane for purification. Because of the membrane''s small pore size, only hydrogen and its isotopes penetrate it. A membrane thus keeps the hydrogen gas at a purity level of two orders of magnitude greater than desiccant or silica gel-based systems. new compressor technology introduced during the 2003 International Air-Conditioning, Heating, Refrigerating Exposition (AHR Expo), held last January in Chicago, may have a significant effect on the future of mid-range chillers and rooftop applications in water-cooled, evaporatively cooled, and air-cooled chilled-water and direct-expansion (DX) systems. Designed and optimized to take full advantage of magnetic-bearing technology, the compressor was awarded the first AHR Expo Innovation Award in the energy category, as well as Canada''s Energy Efficiency Award for its potential to reduce utility-generated greenhouse-gas emissions. The compressor is key to a new water-cooled centrifugal-chiller design, with Air-Conditioning and Refrigeration Institute (ARI) tests indicating integrated part-load values (IPLVs) not normally seen with conventional chillers in this tonnage range.

However, risks abound even with above-ground tanks. Proof of that is found in the nationwide results of the Farmstead Assessment System (Farm-A-Syst). A decade vermeerchippershredder ago, University of Wisconsin water quality specialist Gary Jackson helped develop Farm-A-Syst vermeerchippershredder into a voluntary environmental audit to help farmers identify potential sources of water pollution. In recent years, some form of the program has been adopted in nearly every vermeerchippershredder state."There have been 120,000 farmstead assessments done nationally," says Jackson. "From those surveys, it''s clear that the most common environmental risk on the farm is the petroleum storage area."
