Abstract: A fuel pump system for an aerial refueling system including: a variable displacement motor operable to be driven by a hydraulic fluid pressure; a fuel pump operable to be driven by the variable displacement motor; and a drive system controller (DSC) connected to the variable displacement motor, wherein the DSC is operable to direct an operation of the fuel pump in modes comprising: a flow control mode operable to maintain an output fuel flow rate from the fuel pump to a predetermined maximum inlet pressure at a reception coupling for a receiver aircraft; a fuel pressure control mode operable to regulate the output fuel flow rate to not exceed the predetermined maximum inlet pressure; and a priority mode operable to reduce the output fuel flow rate in response to a decrease in the hydraulic pressure. Also a method of refueling a receiver aircraft.

Abstract: A visualization system for displaying and permitting the mixing, matching, combining, and manipulation of digital pictures related to a number of sources, vendors, and/or digital photograph owners (who may be clients of the system owner, and are hereafter referred to as clients) is disclosed. The pictures in the system, as well as some components of the system itself, offer color correction and/or color calibration, in order to permit users to ascertain the true relational/relative and/or absolute color of the item or items being viewed. The system provides manual and automatic methods for viewing individual digital photographs, and/or combined sets of digital photographs, from one or more angles. The system can provide a sense of movement in relation to items or combined sets of items, which remain combined even during movement and/or manipulation.

Abstract: A combination manual and automatic tracer lathe for cutting a work piece as disclosed. A cutting means for the work piece is movable longitudinally along the work piece and laterally movable into and out of engagement with the work piece while following a pattern. The pattern can be computer generated or mechanically generated with a pattern model. With either model, the cutting means is moved back and forth longitudinally along the work piece as successfully deeper or new cuts are made in the work piece according to the model.

Abstract: A safety tool rest for a lathe having a rotating workpiece is disclosed. The tool rest includes a generally planar base which is attachable to the lathe. An elongate flange projects upwardly and outwardly from the base and has an upper edge which is disposed adjacent the rotating workpiece. A tool for cutting the workpiece rests on top of the upper edge of the flange. An elongate bar is attached to the base but is located above the base at a height higher than the upper edge. In this manner, the tool is inserted below the bar and over the upper edge for cutting the workpiece. The tool is prevented from being flipped about the upper edge during contact with the rotating workpiece by the bar. Preferably, the bar is vertically adjustable relative to the base to accommodate different sized tools. This adjustment is provided by two threaded bolts which pass through the bar and engage the base. A spring is provided around the bolts to urge the bar away from the base.

Abstract: A frozen bread dough which can be prepared from the freezer to a finished baked loaf within about one hour has been accomplished by using a novel process. Because the bread dough is yeast leavened, desirous yeast-leavened flavor and aroma is obtainable. The dough maintains its shelf-life stability through the addition of hydrophilic colloids, film-forming proteins and surfactants.

Abstract: A mechanized reclaiming system for separating ferrous and non-ferrous metals from other materials derived from crushed and shredded automobiles employing a pair of conveyors mounted in a vertical array with the top one separating under vibratory action the small particles of material from the larger particles with the small particles going to a processing tower with this material being processed again into lighter and heavier materials. The lighter material is separated further by centrifugal action while the heavier material is separated into magnetic and non-magnetic material by magnetic means with the non-magnetic material being further separated into light and heavier material through water treatment in a rotating drum.

Abstract: An articulated boom assembly is mounted on a vehicle for swinging movement about a vertical axis. A shear-grapple unit is pivotally attached to the free end of the boom assembly so that after a standing tree has been cut, it may be tilted from a vertical position to a horizontal position. When the cut tree is positioned horizontally above the vehicle, it can be lowered into a stationary delimbing head and also at the same time to a clamping mechanism that travels longitudinally of the vehicle for the purpose of feeding the tree toward a shear mechanism, the delimbing of the tree taking place as this is done. When advanced to a predetermined distance beyond the shear mechanism, the shear mechanism is actuated to sever the first bolt which drops onto an inclined annular plate that has a U-shaped yoke projecting upwardly through its central opening. When the yoke is rotated through 90.degree., a spring yields under the weight of the bolt so that the bolt is free to roll into a collector.

Abstract: A mobile tree delimber having a flail type delimber movably mounted thereon and controllably raised and lowered by sensing means automatically to maintain a selected relative position between the flail delimber unit and the tree or group of trees being processed thereby maximizing impact forces of the flail members on the limbs being removed. A further delimber consists of a mobile vehicle having two or more flail type delimber units individually movably mounted thereon in side-by-side relation and each supported for movement in a vertical plane and means for raising and lowering the respective flail delimber units independent of one another.

Abstract: An automatic tree felling machine is provided. In one embodiment, the machine consists of a self-propelled vehicle having a plurality of automatically operated felling heads, a grapple bunk for skidding felled trees and a plurality of transfer grapples for transferring trees from the felling heads to the bunk. Each felling head is mounted on a transversely extending felling head track that also serves as a sensing means. As the vehicle moves forwardly, the felling head tracks are contacted by trees, causing the tracks to retract towards the machine. As each track retracts, the associated felling head is actuated to travel in a horizontal direction along the track towards the tree engaged with the track while simultaneously travelling downward. Subsequently, the tree contacts a control arm in the felling head which then descends vertically to the stump and fells the tree.
