The 416D has a digging depth of 14 ft. 5 in. with the standard stick and 18 ft. 1 in. with an extendable stick. The 420D has a backhoe digging depth of 14 ft. 5 in. when equipped with the standard stick while the 430D has a digging depth of 15 ft. 3 in. with a standard stick. Extendible sticks push the 420D''s dig depth to 18 ft. 1 in. and 19 ft. 11 in. for the 430D. All three machines now feature 205[degrees] rotation of the backhoe bucket linkage, 40[degrees] more than the C-Series machines. "This new design feature makes it easier to dig vertical walls and to clamp material for truck loading," said Hershberger. In addition, the backhoe buckets now feature single pin position and all former models'' buckets and Cat work tools can be used on the D-Series. The bucket link now has an integrated lifting eye.

U.S. shipments of titanium mill product to the golf club industry peaked at around 10 million pounds in 1996. Today, including the domestic and export markets, shipments are estimated at 2 million pounds by RTI International Metals Inc., Niles, Ohio, with at least half of all drivers using titanium. (Titanium never caught on in a big way for irons.) Nearly all club heads are produced by investment casting. While most of the reduction in U.S. mill shipments was due to the overseas drift of club head production, some measure of the decline also was attributable to a head casting process today that is considerably more efficient than six or seven years ago, when it took roughly twice as much billet to cast and finish a club head than it does today. VSMPO of Russia is described as the dominant source for casting electrodes here.

CPU systems are extremely stable and can be very energy efficient depending on duty cycle especially when combined with parallel LS circuits. Here, the duty cycle of a telehandler makes this very attractive. They feature a simple low-cost open center main valve converted to closed center with tailored spools and offer very good metering to minimize interference when multifunctioning.In the accompanying example, two separate valves art" used to control the functions. A 40 gpm valve is used for the boom up/down and retract/extend. A smaller 20 gpm valve is selected for tilt, frame level, left/right outriggers and auxiliary. An integrated circuit is affixed to the lower flow valve that provides load sense for the brakes, priority steering and pilot pressure. When the lift or telescopic function is activated the orifice is closed off and the pump goes to compensator pressure. It is also true for the tilt, frame level, outriggers and auxiliary functions. This is accomplished by sending the load sense signal through open center core of the 40 gpm valve on to the 20 gpm valve via power beyond. Since the pump in this example supplies only the flow requested any combination of valves is possible.
