The invention comprises, in one form thereof, a water circulator that connects to the pressurized water inlet in a swimming pool. Water from the pool is pumped through the pool's filter system and into the water circulator through the pool inlet. The water circulator includes a jet tube that is vertically oriented and proximate to the pool's side wall. The pressurized water exits the jet tube through several nozzles in the jet tube. The nozzles direct the pressurized water along the side wall to...

A modular tower assembly for use with blown film extrusion processes, where modular tower sections each having identical columns/foot prints can be stacked on top of one another. Each module can have rectangular type platforms with walk decks about a central rectangular void middle. Staircases can be built into the side of all decks modules up to the top deck. Each of the four vertical legs of the deck modules has flat plate bottoms to stack on the deck surface of the module beneath, and side cr...

A swimming pool cleaner is operable through a vibratory movement of its housing through a flow of water past a vibratory element carried within the housing. A friction support is carried by the housing and engages a surface to be cleaned. The friction support has a first end pivotally attached to the housing and a second free end in frictional contact with the surface to be cleaned. The friction support is further biased toward a first orientation and limited in its movement therefrom as the fri...

A method and apparatus for enabling a pool cleaner to travel through a water pool to collect dirt and other debris from the water and/or pool containment wall. The cleaner defines a suction passageway having an inlet open to pool water and an outlet adapted to be coupled via a flexible hose to the suction side of an electrically driven pump. A resulting suction flow, from the inlet to the pump, functions to (1) carry dirt and other debris to a filter and (2) to drive a turbine for propelling the...

An improved layout for a manufacturing facility is disclosed. The layout includes a hub surrounded by a production corridor. The production corridor comprises production stages used in the manufacturing process. The hub, having direct line-of-sight to the production stages, can easily monitor the manufacturing process.

A fence pole clip, comprising two clip sections, the sections having portions configured to conformingly attach to two fence poles, and means swingably interconnecting the sections between the end portions, whereby the sections can be relatively swung to allow positioning of the two clip sections and portions adjacent one of the poles.

A modular stage prop system having a first stage prop and a second stage prop. The first stage prop has a first stepping surface and a plurality of first side surfaces extending from the first stepping surface. The first stepping surface and the plurality of first side surfaces define a first partial enclosure in which an object may be stored. At least one of the first stepping surface and the plurality of first side surfaces has a male connector portion. The second stage prop has a second stepp...

A telescoping pole assembly for an erectable, collapsible shelter, includes first and second hollow telescoping sections slidably connected together, the first telescoping section being slidably disposed within the second telescoping section, and a spring loaded detent pin mounted to the second telescoping section. A weighted internal stop member is slidably disposed within the first telescoping section for movement between a first position and a second position. The internal stop member blocks ...

management device for managing the expiration date of food and drink arranged on a plate and including a camera for capturing a two-dimensional code on a cylindrical base of the plate, a barcode scanner for analyzing the two-dimensional code captured by the camera and extracting a plate number, a management main body for receiving the plate number output from the barcode scanner and collectively managing the traveling plates, and a DIO (Digital Input/Output) module. The DIO module is connected t...

A waterfall for a portable spa does not take up any seat space by being set into the top rim of the spa. Water from the spa circulation system flows into a closed end of a channel located in the top rim and along the channel to the open end located at the edge of the top rim on the inside wall to fall into the body of water in the spa. A light source at the point where the water enters the closed end of the channel, which may be adapted to change colors, directs light into the water flow, lighti...
