Abstract: Stuck well pipe is removed from a well bore by applying an upward pull to the stuck pipe while applying an upward jarring action to the pipe by an air hammer which applies rapid blows to a linkage mechanism connected to the pipe.

Abstract: An electric vehicle power system has a battery system to drive an electric drive motor. A flywheel is provided to supply energy to drive a generator for supplying electric current during peak loads on the battery-motor system and minimize current drain on the battery caused by acceleration of the vehicle. A microprocessor controls the system to apply needed current to the vehicle drive motor or motors. The flywheel is mounted in a vacuum housing which allows angular motion of the vehicle relative to the flywheel to avoid gyroscopic effects of the flywheel on the vehicle. A flywheel is mounted on a horizontal axis in a housing pivotal on a vertical axis, or the flywheel is mounted on a vertical axis in a housing pivotal on a horizontal axis. In one form, the flywheel is the rotor of the motor-generator.

Abstract: A synthetic liner is inserted into a blood vessel in the region of a treated stenosis. The liner is composed of a material resistant to the deposition of the fatty matter from the blood so that the build up of a new obstruction to blood flow is inhibited. The liner is tapered to generally conform to the taper or reduction in cross section of the artery in a downstream direction. The material is resilient and has elasticity compatible with the elasticity of the artery.

Abstract: In the present invention, a sheet-sorter, operating in conjunction with a photocopy machine, has a plurality of trays in general horizontal alignment with the path taken by a sheet of paper discharged from the copier. A tray pusher is arranged to move the lower-most tray in a stack of trays disposed above the paper-path so that the in-board end of the lower-most tray will drop some distance below the paper path, after the sheet has been discharged from the copier. The tray-pusher may be activated by movement of the copier carriage or by an appropriate gear-train connection to a pair of juxtaposed rolls, slightly spaced from each other, constructed and arranged so that one roll will cause the other roll to rotate only when a sheet of paper is disposed between the rolls as the sheet is discharged from the copier. The stack of trays may be re-set manually or by the movement of the copier carriage.

Abstract: An improvement in the mechanism for separating sheet-receiving trays of a sorter for photocopy machines, which increases the capacity of the sorter. A plurality of drive cams each sliding up and down on its own drive shaft, and each having a helical slot on its outer surface, rotate as the shafts are rotated. Trunions extending from the trays engage the helical grooves in the cams, and they, along with the tray to which they are connected, move up or down as the cams rotate. The sorter has improved capacity while yet permitting access between trays. It is simple and positive in operation and provides sorting action in both the upward and downward movement of the cams on the driveshafts.

Abstract: A sheet sorting machine of the movable bin type has a frame structure which supports a plurality of bins at one end of the bins, adjacent to a sheet entry location, the other ends of the bins being free and spaced for removal of sorted sets of sheets. The bins have pairs of trunnions at opposite sides engageable with one another and by pairs of bins shifting spiral cams to raise and lower the bins in parallelism. The trunnions for the bins and the spiral cams are mounted in spring loaded housing with springs which bias the trunnions into the spiral cams, and a trunnion is always in the cam track of the spiral cams.

Abstract: An apparatus is disclosed for receiving sheets from the discharge portion of an electrostatic copy machine, which apparatus receives, stacks and collates the sheets as desired. The apparatus can be electrically independent of the copier and is attached thereto by simple hanger and bracket arrangements. The apparatus includes a plurality of trays which are moved past the discharge opening of the copier, and which are controlled and arranged, selectively to receive (1) a plurality of sheets in each tray; (2) a single copy of each sheet in each of several trays; or (3) a number of identical sheets in one tray and a differing number of other sheets in successive trays. The apparatus can collect, collate, and sort the sheets while the trays are moving in one direction past the copier discharge opening, as well as when the trays are moving past it in the other direction.

Abstract: A sorting machine has bins which are shifted sequentially past a sheet entry location between positions at opposite sides of the sheet entry location, to provide a relatively wide sheet receiving space between adjacent bins at the entry location. The bins have their outer ends pivotally mounted in a frame structure spaced from the sheet entry location, so that the bins slope forwardly. Shifting of the bins is accomplished by a reversible motor driven rotor located at one side of the bins and having recesses to receive trunnions at one side of the bins on each one-half revolution to shift a bin in one direction or the other. The other side of the bin group is unobstructed.

Abstract: A sorting machine is provided to receive successive sheets from an outlet from a copying machine. The sorting machine has plural trays mounted to move progressively past the sheet outlet in opposite directions, the trays being relatively close together when positioned at either side of the outlet, but adjacent trays being widely spaced to accommodate the incoming sheets from the outlet. The trays are fed past and spaced at the outlet by driven members at opposite sides of the tray which engage and shift stacked tray supports in succession.

Abstract: A sorting machine is provided to receive successive sheets from an outlet from a copying machine. The sorting machine has plural trays mounted so that the inlet ends of the trays move progressively past the sheet outlet in opposite directions, the inlet ends of the trays being relatively close together when positioned at either side of the outlet, but the inlet ends of adjacent trays being widely spaced to accommodate the incoming sheets from the outlet of the copier. The trays are fed past and spaced at the outlet by driven members at opposite sides of the tray which engage and shift stacked tray supports in succession. The other ends of the trays are supported for relative angular and longitudinal sliding movements on a vertically shiftable support timed with the feed of the inlet ends to minimize tray angle.

Abstract: A battery charging system for battery-powered vehicles has a battery transfer station, at which a vehicle is positioned for removal and replacement of the spent and charged battery. The spent battery is removed from the vehicle and transferred to a charging system, and a charged battery is transferred from the charging system to the vehicle. In one form, the batteries are conveyed through a continuous charging system, upon removal from the vehicle, and a fully charged battery is deposited in the vehicle. In another form, batteries are transferred from and to the vehicle by a battery transfer system which transfers the batteries to and from storage and charging bays. In all cases, the discharged battery is removed from the vehicle, and a charged battery is installed in the vehicle.

Abstract: A sorting machine is provided for attachment to a copying machine to receive successive sheets from an outlet from the copying machine. The sorting machine has plural trays mounted to move progressively past the sheet outlet in opposite directions, the trays being relatively close together when positioned at either side of the outlet, but adjacent trays being widely spaced to accommodate the incoming sheets from the outlet. The trays are fed past and spaced at the outlet by driven members at opposite sides of the tray which engage and shift stacked trays in succession. The driver members are notched discs functioning as a linear Geneva movement. The remote ends of the trays are freely supported one on the other for relative longitudinal and pivotal movement. In certain forms, the remote tray ends are mounted one on the other by end pieces which have wedge surfaces causing the remote ends to be spaced apart responsive to longitudinal movement of the trays.
