Abstract: A portable solid waste container designed with a central holding chamber. The device features a storage member with a lid that is contained within the chamber. An accessory holding chamber is externally attached to the central holding chamber and is intended to hold a flashlight. A waste bag holding chamber is also externally attached to the central holding chamber and is intended to hold disposable waste bags. The apparatus may be carried by hand by means of an attached handle, or attached to an animal restraining tool, such as a leash or similar device.

Abstract: The present invention is an assembly for pumping liquid at a constant, preselected outlet pressure, and includes an engine connected to a variable displacement hydraulic pump driven by the engine. A fixed displacement hydraulic motor driven by the variable displacement hydraulic pump includes a motor speed transducer. The fixed displacement hydraulic motor drives a liquid pump and contains a liquid outlet pressure transducer. A controller device modulates the output of the variable displacement hydraulic pump. The controller device is in communication with the liquid pump outlet pressure transducer, and with the fixed displacement hydraulic motor speed transducer. The controller thereby modulates the hydraulic output of the variable displacement hydraulic pump to maintain a constant, preselected liquid pump outlet pressure that is independent of engine speed and within the fixed displacement hydraulic motor speed maximum.
