Abstract: An energy generation apparatus includes a first element including at least one first magnet and a second element including at least one second magnet. The second element is movable with respect to the first element. The at least one first magnet and the at least one second magnet are oriented such that common poles of the at least one first and second magnets are temporarily in proximity to each other such that a repulsive magnetic force between the at least one first magnet and at least one second magnet causes relative motion between the first and second elements. Preferred embodiments of the apparatus include at least one positioning element or cam including an undulating or wave-like surface to control a position and/or an orientation of the at least one first magnet and/or the at least one second magnet.

Abstract: A plaster taping apparatus comprises a compartment for holding plaster taping mix and receiving a supply of tape and a removable attachment attachable to the plaster taping apparatus for applying the tape comprising the plaster taping mix exiting the compartment to a surface. The removable attachment comprises a body having a mounting member attachable to a clip arrangement on an outer wall of the compartment. The body comprises a first wheel arrangement at or towards a first end of the body for applying the tape to flat joints and a second wheel arrangement at or towards a second end of the body for applying the tape to internal joints. The plaster taping apparatus comprises an adjustment lever or dial accessible when the removable attachment is attached to the plaster taping apparatus for adjusting a thickness of the plaster taping mix coating the tape.
