A tool for local cooling by contact of a glass sheet at a temperature higher than 450° C., known as a contact tool, includes a contact face suitable for coming into contact with the glass sheet, the tool including an internal pipe for the circulation of a coolant, in particular air. The tool is used in a device for bending and/or cooling a glass sheet, in particular individual, the tool coming into contact with the glass sheet while it is held by a bending tool or by a cooling frame after bending. A compression zone is created that is capable of being drilled to form an edge having compressive stresses.

A coupling (40) for connecting a suction line (31) to a first fluid flow and an exhaust gas flow, the coupling (40) comprising first and second portions (51, 52). The first portion (51) is adapted to receive an end section (34) of the suction line (31) and the second portion (52) is adapted to cooperate with the first portion (51) for engaging a portion of the end section (34) therebetween. The first portion (51) has an opening (63) for receiving an exhaust outlet (16, 17) configured to deliver an exhaust gas flow into the first portion (51). Engagement of the end section (34) between the first and second portions (51, 52) serves to compress a marginal portion of a side wall (37) or side port (36) in the end section (34) of the suction line (31). An apparatus (10) including a rotary tool element (19) and including the coupling (40) is also disclosed.

A floor cutting machine according to the present invention can comprise: a main frame for supporting equipment required for cutting a floor; a plurality of front wheels positioned at the front of the main frame when the proceeding direction of the floor cutting machine is the front and the opposite direction thereof is the rear; at least one rear wheel positioned at the rear of the main frame; a cutting frame which is a frame separate from the main frame, and of which one side is fixed near the rear of the main frame and the other side vertically moves; a cutting shaft positioned near the other side of the cutting frame; and a cutting blade capable of being fitted into both ends of the cutting shaft.

A debris collection system for use in cutting or drilling holes in a ceiling with a hole saw. The debris collection system allows a user to avoid or limit exposure to dust and debris created by cutting or drilling overhead holes in drywall or wood. A clear rigid debris shield is temporarily attachable to the ceiling so that the user does not have to hold it in place while operating the hole saw. The hole saw is operably contained within a debris collection chamber defined within the debris shield when in use. A vacuum hose connects to a vacuum port in a cylindrical sidewall of the debris shield at one end and is attachable to a portable vacuum at an opposite end to create suction and remove debris from the debris collection chamber. A hose hanger is attachable to the ceiling between the debris shield and the portable vacuum to support the vacuum hose and keep it out of the way.

An angle guide assembly for being coupled to a table body that slides along a longitudinal axis relative to a base of a saw. The angle guide assembly includes an attachment member configured to attach the angle guide assembly to the table body; a guide body and an angled fence pivotally coupled to the guide body between a first orientation in which a workpiece can be placed at an angle to the longitudinal axis along a first guide surface of the guide body by placing the workpiece against the fence surface, and a second orientation in which a workpiece can be placed at an angle to the longitudinal axis along a second guide surface of the guide body by placing the workpiece against the fence surface.

A novel cutting method and apparatus includes a cutting blade adapted to consistently and easily form a desirable kerf in a concrete substrate while capturing substantially all resulting concrete dust.

A tile saw includes a saw unit having a motor and a saw blade driven by the motor, a table through which the saw blade at least partially protrudes, and a pan positioned underneath the table and including a channel configured to receive at least a portion of the saw blade. The channel extends along a longitudinal axis perpendicular to a rotational axis of the saw blade such that fluid moves through the channel in a first direction in response to rotation of the saw blade. An interior wall is positioned adjacent the channel. The interior wall is obliquely oriented relative to the longitudinal axis of the channel to redirect the fluid in a second direction that is different from the first direction.

A high-power slurry vacuum cart is well suited to collect and contain any slurry or wet residue produced through concrete and other surface processing operations. A multi-horsepower propane engine and propane tank are mounted on a mobile frame, along with a suction pump powered by the propane engine. A slurry containment vessel mounted on the frame has an input in communication with a squeegee and an output coupled to the suction pump. The squeegee may be adapted for floor contact to collect slurry for transfer to the slurry containment tank. The suction pump is directly coupled to the propane engine through a universal joint, thereby obviating the use of belts, chains or pulleys. The output of the pump may optionally be used as an air blower for surface drying, or the like, as well as use as an air blower to assist in emptying the slurry containment tank.
