Abstract: A hose retractor device including a hose channel mounted on a truck or other vehicle and a pulley movably mounted within the hose channel. A pulley movement device, such as a winch, is connected to the pulley by a winch cable which pulls the pulley into the hose channel towards the winch. An engagement switch engages and disengages the hose retractor device to pull the pulley into the hose channel. The hose extends around the pulley and therefore is pulled into the hose channel for storage thereof.

Abstract: A hand-held shredding device is provided including a housing sized and configured to be hand-held. The housing may include a first opening configured to receive an object to be shredded and a second opening configured to allow the object to exit the housing upon being shredded. A shredding assembly may be disposed within the housing. The shredding assembly may include a first plurality of blades disposed on a first rotatable shaft and a second plurality of blades disposed on a second rotatable shaft. The first and second rotatable shafts may be coupled to one another through a geared connection. The first and second pluralities of blades may be arranged to cooperate with one another to shred the object. A hand-operable crank may be connected to an end of one of the first or second rotatable shafts of the shredding assembly.

Abstract: A portable toilet chemical recharge pumping system includes a water source and a main conduit with a water pump, and a liquid chemical solution source with a chemical conduit and a chemical pump, the chemical conduit connected to the main conduit below the water pump. A water pump timer and a chemical pump timer each engage and disengage the water and chemical pumps, and a chemical flow control valve controls chemical flow through the chemical conduit. An anti-siphon valve on the end of the main conduit prevents unintentional liquid flow, and the water and chemical pump timers and the chemical flow control valve control liquid flow through the main and chemical conduits to provide a pre-injection water flush period, a liquid chemical injection period wherein liquid chemical flows into the main conduit, and a post-injection water flush period wherein water continues to flow out of the anti-siphon valve.
