Abstract:
A portable tank apparatus has a yoke pivotal on a transverse member between a service towing position and a raised position, and a pair of hingedly connected brace members at the rear of the apparatus and operable by an actuator to retract the wheels or lower the wheels to the ground.
Abstract:
A rigid conduit refueling system for aircraft consisting of a wheeled support platform upon which swivel joints connected to a fuel supply source communicate with an arm conduit having a lower end pivotally mounted to the support platform and the upper end communicates with three elbow swivel couplings associated with a nozzle whereby the nozzle may be attached to the aircraft fuel tank inlet. Counterbalancing expansible chamber motors associated with the support platform and arm conduit bear the weight of the elevated components as controlled by a closed fluid circuit.
Abstract:
This invention relates to wheeled load conveyances of the type having a load container to be elevated when the conveyance is not moving and is to be stabilized against movement. The embodiment shown in the drawing is incorporated in a portable water carrier which includes a vehicle frame mounted on wheels and a water tank mounted on the frame by a supporting structure which can be moved to elevate the load above the frame. A stabilizing structure is included to which the weight of the vehicle and the load can be transferred to remove that weight from the wheels. Force is applied to the movable supporting structure to raise the tank and this movement is utilized to transfer weight from the wheels to the stabilizing structure, which in this case is the frame itself. Force is applied by a block and tackle arrangement to raise the tank from the frame. A second block and tackle arrangement utilizes that movement, the relative movement between the frame and the tank, to accomplish relative movement between the wheels and the frame whereby to transfer the load between the wheels and frame.
Abstract:
A portable tank assembly that is movable between an operating position and a transport position that includes a tank assembly with a holding tank having an upper section that includes an upper wall and a lower section that includes a lower wall that tapers inwardly from the upper wall to form an orifice, a transport assembly that includes a base portion and an axle assembly. The base portion is affixed to the upper section of the holding tank, and the axle assembly includes wheels for transporting the holding tank along a surface, and a skid assembly that includes a skid plate configured to rest on a horizontal surface when the portable tank assembly is in the operating position and a plurality of legs connecting the skid plate to the holding tank.
Abstract:
A mobile cart for carrying a plurality of fluid canisters. The cart includes a platform configured to support the fluid canisters. The cart also includes a base having a base body and a plurality of wheels movably connected to the base body so that the wheels can be selectively moved with respect to the base body between an extended position and a retracted position. In the extended position, the plurality of wheels extends from the base body so the cart can roll, on the plurality of wheels, over the support surface supporting the cart. In the retracted position, the plurality of wheels is retracted relative to the base body so that the cart cannot roll, on the plurality of wheels, over the support surface.
Abstract:
A portable tank for handling recreational vehicle liquid waste comprising a molded receptacle of synthetic plastic material having wheels, including a caster wheel. The receptacle is provided with an inlet port for receiving liquid waste, and an outlet port defined in a side of the receptacle is opened and closed by a gate valve permitting the receptacle to be easily emptied.
Abstract:
A handle is engageable with the end coupling of a drain hose for a septic system to facilitate insertion and removal of the hose in and from the storage position in the tubular bumper of a house trailer. The handle provides a grip adjacent the hose axis, and is moveable to a position where the end surface of the coupling is unobstructed.

Abstract:
An automated chemical storage and feed system for a use station to chemically treat and monitor a process at a use station where the process is being run, including one or more base tanks at the use station storing chemicals and having means intermittently or continuously feeding the chemicals to the process. A level sensor is provided in each base tank to determine the chemical level and to deliver a signal to a control and processing unit. Sensors may be provided on the process for generating chemical condition information to the control and processing unit. A telemetry system receives the information from the control and processing unit and transmits it to a supply station where the information is recorded and read out by a person to monitor the chemical supply in the base tank and to monitor the chemical condition of the process so that the chemical feed may be adjusted as needed from the supply station and so that futher chemical may be delivered to the use station to be introduced into the base tank for maintaining an adequate supply to prevent interruption of the process. Refill tanks are shipped from the supply station to the use station, transported to the base tank, and emptied into the base tank. Thereafter, the refill tanks are returned to the supply station to be refilled. A unique hand truck is used at the use station to transport a refill tank to the base tank and to handle the refill tank during unloading.
