Abstract: The present techniques provide multi-layer plastic structures and methods for making such. The multi-layer plastic structures include an inner surface made from a polyolefin resin, and resistant to environmental stress cracking, and an outer surface that includes a styrenic copolymer. The outer surface has a kinetic coefficient of friction with itself of 0.42 and a static coefficient of friction with itself of 0.44.

Abstract: The techniques disclosed provide methods for making and using lamination films having one, two, three or more layers. The two layer lamination films may have an outer protective material comprising a styrenic polymer and an inner sealing material comprising a poly(ethylene vinyl acetate) (EVA). The three layer lamination films add a center adhesive layer comprising a blend of a low density polyethylene and an EVA. Laminated structures using said lamination films are also described.

Abstract: A drive circuit for a stepper motor intended to drive a load, which circuit is adapted to operate in a chopper drive mode during a motor acceleration phase, and an L/R drive mode during a subsequent cruise phase.

Abstract: A coin mechanism comprising a testing mechanism for testing coins as to their acceptability and denomination, an accept/reject gate which is normally in a reject position but is electrically powered to an accept position in response to the testing mechanism determining that a coin is acceptable, and an electrically-actuated coin separator adapted to receive the acceptable coins from the accept/reject gate and direct them selectively towards different destinations in dependence upon their denominations as determined by the testing mechanism, characterised by mechanism adapted to provide power for electrical actuation of the coin separator, following failure of electrical power for the accept/reject gate, for a period sufficient to allow the coin separator to complete the direction towards its correct destination of a coin which has passed the accept/reject gate in its accept position.
