Abstract:

A detachable gooseneck trailer ( ) having a gooseneck ( ) and a detachable trailer deck ( ) utilizes a trailer attachment assembly ( ) to draw the trailer deck ( ) toward the gooseneck ( ) during attachment. The attachment assembly ( ) includes a pivoting carrier ( ) having a retainer leg ( ) with a rearward facing load carrier engagement surface ( ). A slide member ( ) is attached to the trailer deck ( ) and provides a forward facing slide member engagement surface ( ). As actuators ( ) pivot the carrier ( ) rearward, the load carrier engagement surface ( ) slides over the slide member engagement surface ( ). A latching mechanism ( ) utilizes an elongated latch plate ( ) pivotally mounted on the retainer leg ( ) to automatically latch the carrier ( ) to the trailer deck ( ). A latch biasing spring ( ) biases the latch plate ( ) toward its latched position, so that it automatically engages a catch ( ) mounted on the trailer deck. A lift mechanism ( ) utilizes lift actuator arms ( ) extending from the tops of the load carrier ends ( ) to push down carrier arms ( ) and support the gooseneck ( ) above the ground.

An off-load foot ( ) including a downwardly extending leg ( ) having a base ( ) for engaging a ground surface ( ) is utilized to off-load containers. A container lockdown mechanism ( ) includes a securement member ( ) attached to the trailer ( ), an attachment member ( ), and an extension member ( ) extended between the container and the securement member ( ) to hold the container ( ) on the trailer ( ). A bottom wheel assembly ( ), an intermediate lockdown mechanism ( ), a front lockdown mechanism ( ), and a container foot ( ) to transport the containers ( ) with the wheel assemblies ( ) and container foot ( ) attached to the containers ( ). The invention utilizes a universal mounting bracket ( ) which can be used to mount a selected one of the wheel assembly ( ), the container foot ( ), and lockdown extensions ( ) which form part of the lockdown mechanisms ( ).

Appl. No.:

7/121632

Inventors:

Assignee:

Pure Water, Inc. - Lincoln NE

International Classification:

B01D 342
C02F 104

US Classification:

203 1

Abstract:

A distillation type of water purification system has a raw water inlet valve for admitting raw water continuously to a boiling tank at a rate greater than the rate at which raw water is converted to treated water. A drain valve located at the bottom of the boiling tank is energized by a raw water level sensing means whenever the raw water level reaches a predetermined level, to discharge water from the boiling tank. Treated water is stored in a storage tank having a pump for discharging treated water to the user upon demand. A single conductivity sensor in the storage tank controls the pump to allow it to operate only if the sensed conductivity is above a first predetermined value but not at or above a second predetermined value greater than the first value. An improved condenser has two sets of tubes, each set is arranged in a pair of planes oriented transverse the flow of cooling air with the tubes parallel. The internal cross-sectional area of one set is about twice that of the other.

As actuators (70) pivot the carrier (66) rearward, the load carrier engagement surface (90) slides over the slide member engagement surface (94). A latching mechanism (34) utilizes an elongated latch plate (122) pivotally mounted on the retainer leg (84) to automatically latch the carrier (66) to the trailerdeck (22). A latch biasing spring (124) biases the latch plate (122) toward its latched position, so that it automatically engages a catch (126) mounted on the trailer deck. A lift mechanism (36) utilizes lift actuator arms (148) extending from the tops of the load carrier ends (74, 76) to push down carrier arms (144) and support the gooseneck (24) above the ground.
