    Abstract: The invention relates to a system for installing or uninstalling a removable battery of an electric or hybrid vehicle characterized that the system is fully integrated and does not require any outside assistance. To summarize, the jack (3) can vertically handle and drop the battery (2) when the locks (4) securing the battery below the vehicle (1) floor are opened. The unavailable vehicle positioning against the battery dropping location is characterized that it uses the parking assistance system (5) of the vehicle while the device can compensate the inaccuracy gap. This battery dropping system is useful for batteries exchange, for batteries renting or maintenance, and for adapting the batteries configuration to the forecasted load or usages of the vehicle. Important cost cuts, CO2 cuts and fuel savings can be expected from these possibilities. In fact, the vehicle no longer carries a heavy battery when not necessary.

    Abstract: In one embodiment, an extraction apparatus used to pull a golf shaft out of a club head comprises a hosel engagement member, an annular cylinder bore and piston assembly, and a shaft clamping device. The assembly is positioned on the shaft by passing the shaft through an axial hole in the assembly and the hosel engagement member is placed next to the head's hosel. The shaft is clamped in the clamping device so that the hosel, the hosel engagement member, and the cylinder and piston assembly are held tightly against the clamping device. The cylinder is then pressurized, thereby applying a force to the piston and an extraction force to the head which is essentially symmetrical with the shaft. The hosel is then heated to weaken its adhesive bond to the shaft so the piston is able to move and push the head away from the shaft.

    Abstract: A device to remove a metal servo horn in an efficient way by utilizing the lifting force to separate servo horn from a servo output shaft when screw is rotated counter-clockwise and hits against the concave of lower surface of upper front plate of the device. Clamping force provided by two fastening members combines the device and servo horn into one integrated unit to avoid the distortion of open end of the device when lifting force is greater than rigidity of the device. When a lifting force for removing the integrated unit is applied in direction opposite to installing direction of servo horn, it overcomes the friction between the inner splines of servo horn and the outer splines of servo output shaft then separates both splines. The removal of the servo horn from the servo output shaft is achieved.

    Abstract: An assembly tool for assembly of a first component of a prosthesis to a second component of the prosthesis for use in joint arthroplasty. The tool includes a first member operably associated with the first component and defines a first member longitudinal axis thereof. A second member is operably associated with the second component and defines a second member longitudinal axis thereof. A washer system is coupled to the second member. A drive mechanism is coupled to washer system, such that as the drive mechanism is activated, the washer system rotates about the second member longitudinal axis and expands along the second member longitudinal axis, wherein such movement further causes the second member to move relative to the first member along the second member longitudinal axis.

  • Patent number: 8496238
    Abstract: A tubular gripping apparatus has a jaw assembly that has a tubular-contacting surface at an end thereof, a drive yoke that has a tubular-contacting surface at an end thereof, an actuator connected to the drive yoke, and a locking mechanism interconnected to the drive yoke. The drive yoke is connected to the jaw assembly. The actuator moves the jaw assembly and the drive yoke such that the tubular-contacting surfaces thereof move radially inwardly for a substantially identical distance. The locking mechanism directs a load away from the actuator while the jaw assembly and the drive yoke grip the tubular. The locking mechanism has a cylinder yoke positioned around the piston-and-cylinder assembly, and a wedge assembly positioned adjacent the bearing bar and the cylinder yoke.
