A ridge ventilator for covering an open ridge of a roof while promoting ventilation of a space beneath the roof. The ridge ventilator has a sectional body having a first side and a second side, a number of partitions extending across said body between said sides, as well as a first end and a second end. The vent body has a width between said sides to permit said body to be laid over and cover an open ridge in a roof formed at the peak. The body also includes a recessed middle portion in a top face of the body, the recess being sized and shaped to accommodate roofing cap shingles. The body also includes opposed raised and curved, in side view, air foil side sections; which have a grill to permit air to pass therethrough between a space beneath said roof and the outside, the air foil side sections being sized and shaped to create, in a wind passing over the air foil sections, a low pressure adjacent to the grill to facilitate drawing air out of the space.

Ridge vent apparatus

A method for pretreating a wastewater stream containing grease and food particles before the stream enters a sewer includes the steps of directing said wastewater stream to a separation area; directing said wastewater stream along a preferred flow path within said separation area, said preferred flow path being sized and shaped to permit said grease to rise out of said wastewater stream; trapping said grease which rises out of said wastewater stream; extending a wastewater outlet substantially across said separation area; accelerating said remaining wastewater, carrying said food particles, through said outlet from said separation area, thereby sucking said food particles away from said separation area; and directing said wastewater and said food particles toward said sewer system.

Wastewater separator and method of using same

A wastewater separator to separate waste from a mixed wastewater stream including one or more of heavy waste, light waste and water. The wastewater separator comprises a separation container, a inlet and an outlet. The separation container comprises (1) a wastewater stream director within the separation container, the wastewater stream director being sized, shaped and positioned relative to the wastewater inlet to direct the wastewater stream along a preferred flow path to permit the light waste to separate from the wastewater stream in a first direction to a collection area and to permit the heavy waste to separate from the wastewater stream in a second direction towards a heavy waste removal area; and (2) a flow-directing outlet baffle within the separation container for directing the wastewater stream to the wastewater outlet from the heavy waste removal area to remove the heavy waste from the separation container.

A passive venting device for venting a building comprising a base comprising (1) a vent structure for permitting gases to pass in and out of the building; (2) an attachment structure coupled to the vent structure for attaching the device; and (3) a gas-permeable screen sized, shaped and positioned to prevent objects from passing through said vent structure, and having an airflow-enhancing configuration for providing greater airflow area than screens of ordinary sloped configuration; and a cover mountable to the base so as to cover the vent structure and permit the free flow of gas. The gas-permeable screen is spaced from the attachment structure in a direction vertically away the roof.

Vacusweep vacuum inlet valve

A vacuum fitting for connection to a remote source of vacuum, the vacuum fitting comprising a main body mountable to a fixed structure. The main body includes an inlet opening and an outlet opening; an openable closure mounted to the main body and being moveable between an open position and position covering the inlet opening; a latch member selectively positionable to keep the closure in said covering position when positioned between the main body and the closure and to permit said closure to move to an open position when not positioned between said main body and the closure; and a biaser to urge the closure to an open position. A switch is also provided to initiate the remote source of vacuum when the closure is moved to the open position by the biaser.
