Abstract: A driving device, comprising a hand-held housing with a piston element arranged therein for transmission of energy to a fastening element to be driven in a driving direction, a propellant charge, and a combustion chamber, which is arranged between the propellant charge and the piston element and extends around a central axis, and an actuator, by which energy to be transmitted from the propellant charge to the piston element can be varied in such that the energy can be set, wherein the combustion chamber has an internal thread and a cylindrical guiding portion, wherein the actuator is arranged in the combustion chamber and has an external thread in engagement with the internal thread and a bearing for mounting the actuator in the guiding portion, wherein a thread gap spacing between the external and internal threads is greater than a bearing gap spacing between the bearing and the guiding portion.

Abstract: A power tool, comprising first and second module, removable from the first module, the first and second modules being insertable into one another along an insertion axis defining an insertion direction, the first module having a pressing inhibiting element, moved along with the second module, and a pressing blocking element, the inhibiting element being turnable with respect to the blocking element about the insertion axis between normal and detaching positions, the second module being held against the first module in the normal position and removable from the first module in the detaching position, the blocking element allowing the inhibiting element to be transferred along the insertion axis toward the first module into a pressing position when the inhibiting element is in the normal position, the blocking element blocking the insert fitting from being transferred into the pressing position when the inhibiting element is in the detaching position.

Abstract: A computer system has a liquid cooling system with a main portion, a cold plate, and a closed fluid line extending between the main portion and the cold plate. The cold plate has an internal liquid chamber fluidly connected to the closed fluid line. The computer system also has a hot swappable computing module that is removably connectable with the cold plate. The cold plate and computing module are configured to maintain the closed fluid line between the main portion and the cold plate when the computing module is being connected to or removed from the cold plate.

Abstract: A computer server rack has a platform, configured to support at least one server, with a front end and an opposed back end. The server rack also has a height adjuster coupled to the platform, and a control positioned a first distance from the front end and a second distance from the back end. The first distance is smaller than the second distance, and the control is configured to control the height adjuster to change a height of the back end of the platform.

Abstract: A fusion reactor that has a multiple of fuel rings per second that spin in a spiral form. The fusion reactor produces a sustainable, controlled fusion reaction that produces more energy than it uses. The reactor employs a system of resonant magnetic fields that control the direction of the fuel particles' momentum and polarity, and neutralizes the interactive forces of the fuel particles linear Coulomb repulsions. The rotating ring has a geometric rate of radius reduction for ring stability and efficient fusion reaction. Preferably, a stream of lithium nuclei are utilized as fuel. In merging lithium nuclei within the controlled spiral of a resonant magnetic field, positive alpha charges are produced. These high-energy alpha charges are then directed into a generator for the purpose of pumping electrons to produce electricity.
