The vertical portion also includes two lateral ears that each have an end defined by a notch and are adapted to be mounted to side frames of the hand truck.

Abstract: A twin-lever drive wheel steering mower for a sitting operator with each lever independently controlling a brake and the speed of each drive wheel through a separate hydraulic pump and motor transmission. A brake positioned on each drive wheel; a pair of pivotally mounted steering levers, each controlling one of said pumps mounted on the mower for longitudinal movement, each steering lever is connected independently to the swash plate of its controlled pump providing variable speeds forward, reverse, and a neutral zero flow position; linkage members connecting the steering levers for each wheel to said brake on each wheel; a pair of T-shaped slots having a lateral leg in a cover plate surrounding each of the steering levers allowing the levers to move laterally outward in the lateral leg to engage the brakes only in the neutral position.

Abstract: A modular camera support and extension structure which removably mounts on the seat tracks of a conventional aircraft and extends through a cargo pod door during usage, including a box structure containing a plurality of vertical rails which support a tracking plate positioned inside the box structure with linear bearings around its periphery, slidably mounted on said rails for vertical movement from a retracted position to an extended position; a camera rotatably mounted on the bottom of said tracking plate about a vertical axis; a pair of actuating sprockets connected by a drive chain mounted on the box structure, the drive chain is connected to the tracking plate for moving the FLIR camera from its retracted position to its extended position; a box frame structure mounted on the aircraft skin which includes stops on the box frame which lockingly engage the tracking plate in its extended position.

Abstract: An adjustable length cargo brace for restraining loads in semi-trailers comprising two legs, one connected to the other for through an offset collar permitting a limited pivotal and sliding movement between the two legs, a pin member on one of the legs approximate the offset collar which releaseably engages one of a series of openings positioned longitudinally along the opposite leg to engage the two legs together in a pivotally toggled action as they move into parallel contacting relation and a releaseable hook member mounted on one of the legs for engaging and retaining the other leg in parallel contacting relation.

Abstract: The invention provides a quick disconnect mounting system for cabinets and partitions which entails only the removal of one or two bolt fasteners on the bottom of the cabinet and a pair of retractable pin fasteners on the upper portions of the cabinet, with an optional retractable pin fastener in the center rear of the cabinet. Each of these acoustical mounts are insulated, thus preventing vibration in the structural portion of the fuselage from entering the passenger compartment.

Abstract: A dual position hand truck includes a central frame having two side rails and a toe plate. Positioned at an upper end of the central frame is a U-shaped handle bar which has a hand gripping portion and two extended legs with castered wheels attached at their respective bottom ends. The handle bar is pivotally attached to the frame by a fixed shaft and a pair of support brackets. The support brackets also allow the extended legs to slide along their length. Attached to the support brackets is a spring biased locking bar which locks the handle bar against rotational movement relative to the frame.

Abstract: An electronic self-powered propeller governor driven off the aircraft engine includes a drive shaft which drives a hydraulic pump to produce pressurized oil to move a hydraulically controlled piston connected to the propeller blade for changing the blade pitch. A hydraulic control valve which controls the position of the piston includes a spool which is positioned within the drive shaft and supplies pressure to the piston for changing the pitch of the propeller blade. The drive shaft also drives an AC generator producing an electrical RPM signal which is supplied to a linear control circuit. A manually operated RPM control produces an electrical signal supplied to said linear control circuit which is compared with the RPM signal produced by the generator and in turn the linear control circuit signals an actuator.

Abstract: A method of making an open mouth vessel with undercuts on the inside including the method steps of injection molding a cylindrical shape preform having a closed bottom and open mouth top with a lip therearound including a pouring spout in the lip; placing the preform in its molten state in a split blow mold, which mold supports and retains the bottom, lip and pouring spout in its original shape and pressurizing the preform to blow-form the cylindrical wall to the shape of the blow form mold.

Abstract: A multi-blade mower deck having a center right and left blade chambers, which are partially connected to each other, each blade chamber including a rotary mounted cutting blade with lifting sails thereon for rotating and lifting the air into each blade chamber, a front skirt defining portions of said blade chamber; a continuous rear skirt wrapping around rear portions of each of said blade chambers; and a fan chamber positioned above the cutting deck and concentrically aligned over the center blade chamber and having an opening into the center fan chamber including concentrically mounted impeller blades for driving air and clipping from the fan chamber through a exhaust passage positioned over the cutting deck.

Abstract: The present invention provides a turning apparatus for receiving large bales from a baler, the apparatus includes a table for receiving the large bales which turns the bale ninety degrees from its original position as it exits from a baler and then tilts the table downward thus rolling the bale off the table. The table angle and its turning speed are adjustable for varying the position in which it is deposited off of the table.

Abstract: An adjustable width livestock working alley for handling various size animals including a stationary support frame supporting a first arcuate-shaped stationary outer wall and a second arcuate-shaped moveable inner wall including multiple sections, pivotally joined together at the ends of the sections so that the effective radius of the overall inner wall can be changed. A series of connecting links, connecting the support frame to the multiple arcuate sections at their pivot joints with each connecting link starting with the first link having the shortest length with the links of each additional section being proportional to the accumulated changes in the circumferential length of the wall sections as the effective radius of the inner wall is changed and power means connected to the multiple sections for moving those sections radially and longitudinally to change the effective radius of the inner wall.

Abstract: The present invention is directed toward a loader bucket which has a back bucket assembly, a front bucket assembly that pivotably mounts to the back bucket assembly forming an extension thereof in the closed position and an actuator for pivoting the front bucket assembly relative to the back bucket assembly. The front bucket assembly includes an ejector panel that is adapted to swing behind the front bucket assembly and through the back bucket assembly as the front bucket assembly is pivoted by the actuator relative to the back bucket assembly. As the ejector panel sweeps through the back bucket assembly it sweeps out of the back bucket assembly without dumping the back bucket assembly. The lower wall of the back bucket assembly is cylindrically contoured to closely clear the ejector panel as it sweeps through the back bucket assembly.

Abstract: A directional horizontal boring backreamer for enlarging an initial bore, including three equally spaced radially extending wings attach to a common axle, equally spaced around the axle, each wing including a plurality of cutters positioned along the wing for enlarging the bore, and attached to each wing is a gusset plate welded to the axle at the juncture of the wing and axle and to the wing for added bending strength to the wing. The gusset plates also including an internal passage way from the center passage of the axle to the outer edge of the wings to support and supply a series of fluid jets supplied by fluid for assistance in cutting during the backreaming operation.
