Abstract: A shift assembly for shifting the gears of a transfer case of a vehicle as between two-wheel drive, four-wheel drive, neutral and four wheel drive range. A mounting plate rigidly mounted to the transfer case has a bottom configuration characterized by two cut out portions separated by a dependent landing portion. The shaft rod and its support housing are pivoted to the plate with a locating pin protruded from the shift rod through the housing and into the configured cut out portions of the mounting plate. The shift rod is biased upwardly relative to the support housing and is retained by the upward biasing into whichever of the cut out portions it is positioned. Repositioning is accomplished by depression of the rod against the upward biasing and pivoting of the rod to position the locating pin to the other cut out portion or on the landing portion separating the cut out portions. A depression in the landing portion identifies the neutral position.

A pivotal ramp guides tree stems into and through the side entry. With the ramp in a lowered position a skidder-type stem hauler directs the tree stem bundle to be ramped upwardly into the side entry. With the ramp in a raised position a boom mounted grapple directs the tree stem bundle to be ramped downwardly into the side entry.

Abstract: The inclusion of computer capability to process Workers' Compensation claims wherein a complexity of administrative rules determine maximum allowable benefits, the processing of which is not feasible for manual processing. The rules are converted to computer computations entered into the computer's memory. A computer process is devised to systematically examine the rules as they apply to a specific billing. In particular, the various modifiers that affect the allowable pay out are determined through this computer processing. Pre-stored information on prior billings for the same injury is considered for further modification of the allowable billing amount.

Abstract: An electronic foot pedal for diesel engine control systems. The pedal provides a voltage signal to a diesel engine electronic fuel control system in response to the drivers demand for engine power. Disclosed is an accelerator pedal assembly containing a potentiometer and pedal interfacing components which provide a voltage signal proportional to pedal position. The pedal assembly is an integral unit which is cab mounted and connected to the engine fuel control via an appropriate wiring harness. An idle stop pin provides a positive pedal idle position. When the idle stop pin is removed, the bias spring load forcing the pedal toward idle is relieved allowing easy assembly of the device.

Abstract: A cutting saw chain for aggregate materials including a loop of articulated chain links adapted to fit the guide bar of a chain saw. The guide bar is provided with a flushing system whereby pressurized water is directed through the bar and into the path of the guided saw chain to cool the chain and flush away debris formed in the cutting operation. The cutting link structure is a folded plate-like member formed into spaced side plate portions and an overhead connecting web. The side plate portions function like side links in a conventional saw chain and ride on the rails of the guide bar. Rivet holes are formed in the side plate portions. Rivets projected through the rivet holes connect the side plate portions to front and rear center links. The side plate portions are fixed in spaced relation by the connecting web an permits the use of rivets with straight shank. The connecting web supports front and rear sections of a cutting block.

The connection is designed to translate the traditional pedal movement to the required spool rotation as needed for monitoring by the potentiometer.

Abstract: A system for detecting offsize defects and for segregating the veneer sheets containing the defects from the non-defective sheets. Scanners are positioned along the in-feed conveyor leading to the clipper. As offsize defects are identified, a computer determines which of the sheets to be cut will contain the defects. These sheets are segregated as by diverting them to a pull chain conveyor following the cutting of the sheets from the continuous sheeting. Dye is sprayed on the area of the defects as detected by the scanners to aid in further handling of the defective sheets when removed from the pull chain.
