Fused fluxes are melted in a furnace, chilled, then crushed and screened for size. These pickup little moisture and recycle without alterations in particle size or composition. Bonded fluxes are powdered materials mixed dry and bonded together with a silicate, pelletized, baked, broken up, and screened for size: the process permits easy addition of deoxidizers and alloying elements. Bonded fluxes allow thicker flux layers when welding and can be identified quickly by color. Disadvantages of bonded fluxes are their absorption of moisture and alterations during handling in panicle size and composition due to particle segregation. Agglomerated fluxes are similar to bonded fluxes except that they use a ceramic binder. They require higher baking temperatures during manufacture, which limits additions of deoxidizers and alloying elements. Mechanically mixed fluxes are combinations of two or more bonded or agglomerated fluxes. They allow special flux mixtures for critical welds, but they may separate during storage, use, and flux recovery.

DR POWERWAGON: Next size down in size and capacity are the DR Powerwagons--a unique line of powered garden carts made by Country Home Products, Meigs Road, P.O. Box 25, Vergennes, VT 05491; (800 711-7276. All sizes are tank-tough and capable of hauling 800 pounds of bricks, firewood, garden compost or rocks. They are maneuvered by hand with stout handles and castoring wheels at the back, thus avoiding the steering mechanism that would boost their cost. GARDEN WAY CARTS: And finally, if a powered hauler is more than you can justify, get yourself a shiny, metal frame and brown stained, plywood box-bodied Garden Way-style garden cart like you see in many rural and sub-urban gardens. These carts were designed by Garden Way founders Eddie Robinson and Lyman Wood back in the 1940s; they took their inspiration from the amazingly well-balanced, high-wheeled railway station baggage cans of the day. You may remember Garden Way carts from the magazine ads that compared their lightweight and easy-dumping gardening convenience with a tippy, back-straining wheelbarrow. Perfectly balanced on easy-turning, rustproof, chrome-plated spoked wheels, a box cart will let you haul bulky or heavy loads of all kinds over an acre or so of flatland. A word of caution: Don''t overload them. I once boldly filled a small model #16 (so-named for its 16-inch wheels) with 200 pounds of flatrock and pulled it down a foot-high patio ledge. The load (twice the cart''s rated capacity), collapsed the spokes in both wheels.

This exercise was conducted to improve performance of an existing open center system. Reduced horsepower consumption also resulted in the elimination of the oil cooler. Correct sizing of components is essential for maximizing system efficiency. Simply evaluating the cost of each component will obscure the overall savings achieved by integrating a complete system.A significant benefit to this system versus pressure compensation is the simplicity. Compensators can misbehave. An open center valve has far fewer moving parts and rarely suffers front debris getting lodged in small opening. Anyone who has been in the position of analyzing a pressure compensated valve problem in the field can attest to the difficulty of determining what combination of factors brought on rite problem. The fewer the variables the better. Princeton Delivery Systems, a leading North American manufacturer of material handling equipment, recently unveiled the latest generation in its line of Piggy Back track-mounted forklifts. The PB50 and PB65 incorporate a range of improvement from their predecessors and mark one of the first applications of Caterpillar''s new four-cylinder 3024 compact diesel engines.
