A tile saw splash guard and reservoir system has a splash guard, a water reservoir, a pump and tubing for use on a tile wet saw. Water from the tray of the saw spills over into the reservoir and is pumped to the cutting blade to lubricate the blade. The splash guard directs overspray and spillage of water and sediment into the reservoir. Some embodiments have a spillover tube at the drain hole of the tray. Sediment from cut tile settles to the bottom of the reservoir, allowing clean water to be pumped. The system keeps the work area clean and extends the amount of time a conventional tile saw may be used before having to be cleaned.

The present invention relates to a system and method for cutting and manipulating the used wind turbine blades for disposal.

A sawblade for a circular saw, including a round, disk-shaped core blade made from one or more parts, with a plurality of circumferentially distributed saw teeth being arranged at its external perimeter and with its center comprising a connection for fastening the sawblade at a driveshaft, and at least one side area of the core blade including open channels 7 for guiding liquids. A circular sawing machine having such a sawblade and a method for producing such a sawblade are also provided.

A circular sawing machine having such a sawblade and a method for producing such a sawblade are also provided.

The present invention relates to a laying machine for laying at least one flexible casing or tube, cable or wire including: a blade arrangement for making a trench in the ground, a consolidation and laying means being arranged behind the blade arrangement, for clearing and safe-guarding the trench from collapsing while laying at least one flexible casing or tube, cable or wire into the trench. A blade assembly comprising compartments for cooling fluid and air.

Provided are a recirculation system (200) for a material removal machine (102) and a material removal system (100). A material removal system (100) includes a recirculation system (200) in fluid communication with a material removal cabinet (104) housing a material removal machine (102). The recirculation system (200) may have an upper reservoir (300) configured to drain fluid into a lower reservoir (204) before recirculating the fluid. The upper reservoir (300) may have a standpipe (320) configured to allow swarf, debris, and/or other material within the fluid to be entrained prior to flowing over the standpipe (320).
