Abstract: Systems and methods are disclosed that generate Non-Fungible Tokens (NFTs) at a point of sale using a QR code and a private key. The systems and methods can also be used to verify the purchase of a ticket to a real-world event such as a concert for display, purchase, or sale in the so-called Metaverse. The systems and methods can be used to verify the source of a credential such as a diploma, degree, or certification of any kind. The systems and methods mint NFTs that can be used to prove the source or authenticity of the real-world product, event, or credential. The requestor of the verification can be a 3rd party such as a social media, ecommerce, or dating platform.

Abstract: A hand-power tool includes at least one oscillation-damping device that has at least one damping spring, a damping mass, and a mechanism housing. The oscillation-damping device has at least two retaining parts that at least partly enclose the damping mass.

Abstract: A hand-power tool includes at least one oscillation-damping device that has at least one damping spring and a damping mass. The hand-power tool also includes a drive mechanism and a mechanism housing. The mechanism housing has a housing cover which is provided for closing a chamber in which the drive mechanism lies, and the housing cover has at least one fixing mechanism that at least partially fixes the oscillation-damping device in at least one operating state.

Abstract: The invention is based on a handheld power tool, having at least one vibration-cancelling device that has at least one cancellation spring and one cancellation mass. It is proposed that the cancellation mass is constructed of at least one first mass part and at least one second mass part.

Abstract: The invention relates to a hand-held machine tool, particularly to a drill hammer and/or chisel hammer, having a hand-held machine tool housing and a transmission chamber with at least one transmission element arranged inside the hand-held machine tool housing. According to the invention, the hand-held machine tool includes a pressure equalization unit, provided for equalizing pressure in the transmission housing and serving at least partially for supporting the transmission element.

Abstract: A method is provided for forming an end closure for a surrounding sidewall of a container, such as an aluminum can. The method includes forming a central body panel oriented transversely to the central axis of the can and forming an outer surrounding margin portion joined to the sidewall such that the margin portion has a support section oriented longitudinally relative to the sidewall. A portion of the margin is corrugated to provide a rib structure having longitudinally extending first rib components located on the support section. This method can be accomplished during the ironing and doming of a can.

Abstract: Apparatus for applying a coating material, such as a lubricant, to the top and bottom surfaces of a continuous strip of material wherein the continuous strip of material is passed between two wicks mounted in each of an upper and lower housings with each of the housings having a plurality of spaced apart bores and wherein metered amounts of the coating material is supplied sequentially to each of the plurality of spaced apart bores by a piston mounted for reciprocating movement. In another embodiment, the wicks apply coating material to the outer surface of an upper drive roll and a lower idler roll so that coating material is applied to the upper and lower surfaces of a continuous strip of material as it passes therebetween.

Abstract: A device for measuring electric current includes a toric core having a gap that establishes a pair of opposed end faces, and a continuous conductor having terminal ends and wound around the core in contiguous turns forming a toric solenoid interrupted by the gap. The solenoid has first and second ends adjacent the respective end faces of the core, and the conductor at each end of the solenoid passes through the core and extends along the axis thereof from the opposed end faces of the core such that the terminal ends of the conductor are located diametrically opposite the gap. A first compensation coil is serially connected to said first end of the solenoid such that the first coil overlies the first end of the solenoid to which the first compensation coil is connected.

Abstract: A base coat applicator utilizing an in-feed chute which provides supply of cans which are mounted on mandrels for application of base coat material by applicator wheels. The mandrels are rotated so that surface speed of the cans matches the applicator wheel speed to prevent smearing. Independent control of the inventory production speed of the base coat applicator machine and the applicator wheels allows any desired number of base coat layers to be applied to the cans. Two applicator wheels are used to reduce surface speeds to prevent misting and slinging of base coat material from the applicator wheels and can surfaces. The applicator assembly is automatically withdrawn when the supply of cans is not present and can be manually withdrawn by the operator to prevent application of base coat material to cans or empty mandrels. Disk transfer unit is utilized to transfer the coated cans to a deco pin chain.
