Abstract: A wastewater treatment system for use on marine vessels or land-based applications treats wastewater by solids separation and oxidation. The system includes a solids separation tank, an oxidation tank having a plurality of chambers and a fluid circuit for re-circulating treated wastewater into the solids separation tank and oxidation tank for further treatment. An ozone generator produces ozone which is dissolved in the treated wastewater in the re-circulating fluid conduit and is used for the solids separation and oxidation processes. The treated wastewater is periodically discharged into the environment.

Abstract: An apparatus for loading and un-loading a recreational vehicle from a truck. The truck has a front and rear and a longitudinal axis defined therebetween. The apparatus comprises, in one embodiment, a vehicle receiving ramp and a lifting mechanism engaged with the underside of the ramp. The lifting mechanism is mounted to the rear of the truck and is selectively operable to arcuately move the ramp between a lowered position that is inclined with respect to the longitudinal axis and a raised position that is parallel with the longitudinal axis. The ramp is longitudinally mobile in the raised position between a foremost and rearmost position and is selectively lockable in the foremost and rearmost positions using a locking mechanism. To load the recreational vehicle, the ramp is preferably locked in the rearmost longitudinal position and placed in the lowered position for receiving the vehicle.

Abstract: Disclosed is a wallet in the form of a harness with an attached key ring for carry credit cards and folded paper, such as paper currency, together with keys. The harness comprises two loops of elasticized material attached to each other at opposing points such that one loop encircles the length of the credit cards and the other loop encircles the width of the credit cards. The loops may comprise a buckle and may be adjustable to accommodate more cards. The key ring may be used to facilitate opening and closing of the harness.
