Abstract: A racking mechanism for moving elements of a mobile electrical substation between a transport mode and an operational mode is provided. The racking mechanism includes a fixed structural member; a moveable structural member; and a bearing disposed between a side surface of the fixed structural member and a side surface of the moveable structural member.

Abstract: A method and apparatus are disclosed for staggering execution of an instruction. According to one embodiment of the invention, a single macro instruction is received wherein the single macro instruction specifies at least two logical registers and wherein the two logical registers respectively store a first and second packed data operands having corresponding data elements. An operation specified by the single macro instruction is then performed independently on a first and second plurality of the corresponding data elements from said first and second packed data operands at different times using the same circuit to independently generate a first and second plurality of resulting data elements. The first and second plurality of resulting data elements are stored in a single logical register as a third packed data operand.

Abstract: A novel mechanism is presented that is able to harvest and load and to unload and install large rolls of sod with only one worker. It is equally useful with conventional sods grown on soil as well as sods grown over an impervious surface. The device is attached by a shiftable bracket to the utility mounting plate and hydraulics of a suitable tractor, skid steer loader, or modified fork lift. It consists of a steel spear or prong attached to a clevis that rotates slightly more than 180 degrees. Cones are placed on the hinged spear and these position PVC pipe or other tubing of the same length as the sod roll desired. The spear with cone(s) and tubing is placed at a right angle, either to the left or right, of the direction of the loader and dropped to the surface at the end of a cut sheet of sod. Small protrusions or prongs on the surface of the tubing lightly grasp the sod and begin rolling it up on the tubing.

Abstract: A crane for material handling is constituted by a boom (1) and a fixed column (2) for supporting the boom (1). The boom (1) is articulated for vertical swinging movement on and relative to a rotating device (3), mounted for rotation about a vertical axis on or in the column (2) and provided with a torsion-transmitting member (4) passing through the column (2) and coacting at its lower portion with a rotation activator (5) of the boom (1). The boom (1) is provided at its free end with a hook, a grapple or another tool, or with a like rotatable actuator.

Abstract: An apparatus is designed to rotate a vehicle by ninety degrees for repair of the under carriage of the vehicle and other parts accessible from the bottom. The preferred vehicle is a forklift, and a mast support is provided to be secured to the mast of the forklift. Wheel supports are provided which may be rotated out of engagement with the wheels when the vehicle is vertical to allow unobstructed access to the vehicle. Removable support bars may be used in place of the wheel supports to engage the bottom of the vehicle during rotation. The apparatus sits on a flat floor and does not require approach ramps or the like. The apparatus may be moved to any location and is symmetrical so that it may be placed against a wall on the left or right by a simple interchange of parts. A jib is provided which may be used to hoist heavy parts of the vehicle.

Abstract: A remote controlled self-loading truck having a tilt bed equipped with a bed mounted hoist and having fold-down sides, and for mounting on standard truck chassis. An elevated hoist is supported on the tiltable bed adjacent to its forward end for movement with the bed. The hoist includes an elongated generally horizontal rearwardly extending rotatably supported boom. A tail roller is journaled for rotation at the rearward edge of the flat bed. Hinged side gates are provided on opposite sides of the flat bed. Remotely manually controlled hydraulic actuators are provided for raising and lowering the bed relative to the vehicle frame, for rotating the hoist boom, and for operating the hoist winch.

Abstract: A lightweight, self-powered, transportable crane assembly is disclosed which includes a frame that can be selectively coupled to and uncoupled from the bed of a transport vehicle or carrier, such as a pick-up truck or trailer. The frame assembly also includes stabilizing legs which can be extended laterally from the frame assembly to stabilize the crane during use and further to allow the crane assembly to be self supporting apart from the truck or trailer. The crane assembly also can be coupled to a ballast structure such as a water tank or the like, to permit its use apart from the transport vehicle.

Abstract: In a working vehicle including a crane (21) for handling loads and a driver's cab (11), both crane and cab are rotatably mounted on the vehicle, each about its vertical axis, and controlled such that a turning angle .beta. of the crane results in a turning angle .alpha. of the cab, .alpha. being an optional function of .beta., e.g. half of .beta.. The driver can thus carry out all the working operations desired for the crane without having to turn his head uncomfortably.

Abstract: A log handling attachment for a bulldozer or similar vehicle consisting of a bracket assembly arranged to be detachably mounted on the rear portion of the vehicle and carrying a horizontally rotatable articulated boom provided with hydraulic cylinders for moving the pivoted parts of the boom, and provided with a hydraulically-driven gear and sprocket chain system for swinging the boom around a vertical axis through a wide angular range. A hydraulic winch is mounted on the boom, having a long cable running through sheaves on the boom and provided with a log-engaging tool at the end of the cable. Operating power is derived from the power take-off shaft of the vehicle.

Abstract: A barge loading device comprising a vertically disposed support tower positioned between a pair of barges or the like. A boom is rotatably mounted on the support tower and extends outwardly therefrom. A vertically disposed telescopic spout extends downwardly from the outer end of the boom. A conveyor is provided on the support tower and the boom for supplying grain or the like to the upper end of the spout for delivery to one of the barges. The boom may be rotatably moved relative to the support tower to facilitate the loading of the barges on either side of the tower. The spout may be tilted to either side of its normally disposed vertical position and may be rotated about its longitudinal axis. The combination of the rotatable boom, tilting and rotating spout permits greater areas to be filled in the barges.
