Abstract: Disclosed is a distributed blockchain system and method for blockchain transactions for users for a virtual environment. The virtual environment has at least one or more of virtual space, time, virtual objects, and avatars, inclusive of a game environment, wherein users execute moves, the moves allowing users to earn from outcomes of moves at least one or more of tokens, skills, and tools, the tools being an element of the virtual objects and the skills being an element of the avatars. A validator is designed to validate moves and move outcomes. A transaction aggregator is designed to accumulate related layer-one transactions in the blockchain. The accumulated related transactions are viewable on one or more user interfaces wherein at least one or more of moves, outcomes of moves, associated non-interchangeable units of data, the tokens, the tools, the virtual transaction space, the time, the virtual transaction objects, and the avatars.

Abstract: A damping device for a printing hammer which is driven by an electromagnetically actuated pivotable armature has a circuit associated therewith for operating the electromagnetic coils which generates a high excitation current for rapid acceleration of the armature and printing hammer which is followed by a switch over to a considerably lower holding current which maintains the armature in a position to abut the printing hammer during its return stroke. The armature also actuates a rotatable angle lever into engagement with the printing hammer for frictional braking thereof so that the hammer is rapidly damped to a rest position and is ready for a subsequent printing stroke.
