In one embodiment, systems and methods include using an ultrasonic cutter in a ground detection system to prevent damage to a substrate. The method of detecting a substrate comprises attaching a workpiece clamp to the substrate. The method further comprises cutting a layer of coating disposed on the substrate with an ultrasonic cutter, wherein the ultrasonic cutter operates at a frequency of about 20 kHz to about 40 kHz, wherein the layer of coating is non-conductive. The method further comprises contacting the substrate with the ultrasonic cutter.

A slicing apparatus for slicing food articles includes a food article loading apparatus with a lift tray assembly for moving food articles from a staging position to an elevated position at a beginning of a food article feed path, a food article feed apparatus disposed over the food article loading apparatus having an upper conveyor assembly with an independently driven endless conveyor belt used in cooperation with a food article gripper for moving the food articles along the food article feed path, a food article stop gate that forms part of the food article feed path and opens to drop food article end portions, and a slicing station at an end of the food article feed path with a knife for slicing the food articles.

A device and a method for cutting a loaf of bread in slices having an input compartment adjacent to a set of parallel oblong blades which can be driven back and forth in their longitudinal direction. A pusher movable between a retracted position in relation to the blades and an end cutting position pushes the bread through the blades. A detector is provided to detect the presence of an object in the access opening of an input compartment which cooperates with the blades' drive to stop the movement of the blades when the presence of an object in the access opening is detected. When the presence of an object in the access opening is detected while the pusher is in its retracted position, the movement of the blades starts and the pusher will be moved from its retracted position to the end cutting position when the object is no longer detected in the access opening.

An article of manufacture for an all-in-one beauty product extraction device is disclosed. The extraction device comprises a device frame, a soft tube capture slot, a locking and sealing arm, and a cutting handle. A safely-contained cutting blade is coupled to an underside of the cutting handle. The cutting handle wraps around the locking and sealing arm such that the cutting handle may slide up and down the length of the locking and sealing arm to cut the soft tube. Leaving the locking and sealing arm in a closed position seals the soft tube by pinching the opened end shut between an edge of the soft tube capture slot and the locking and sealing arm.

A bread cutting machine has a circular blade that is moveable in a guide gap through an extension gap of a machine housing from a waiting position into a cutting space. When the blade is in the waiting position, the guide gap is coverable by a rocker displaceable away from the guide gap simultaneously with the extension of the blade from the waiting position, whereby the guide gap is opened. A cover plate is rigidly fastened to a side surface of the rocker, projects vertically away from the rocker, and covers the extension gap whenever the blade is in the waiting position. By a positive guide, the cover plate is moveable away from the extension gap simultaneously with the movement of the rocker, whereby the extension gap is opened.

A table saw including a table having a top surface, an opening in the table through which a saw blade extends, and a throat plate receivable within the opening. The throat plate includes a front end that sits flush with the top surface of the table, a back end that sits flush with the top surface of the table, a top surface that is co-planar with the top surface of the table, and a wear plate pocket that is recessed from the top surface of the throat plate. The wear plate pocket defines a bottom surface that is oriented at an oblique angle relative to the top surface of the throat plate and slopes downward in a direction from the back end toward the front end. The wear plate positioned within the wear plate pocket. The wear plate sitting parallel to the bottom surface of the wear plate pocket.

A method for the cutting of material is to be cut by means of a cutting machine which includes a horizontal cutting support for material to be cut, a horizontal cutting blade displaceable in height above the cutting support for cutting the material to be cut supported on the cutting support, a drive motor for the height displacement of the cutting blade, a manual control for the drive motor, and a protection device safeguarding the working region of the cutting machine. The method has the steps of: lowering the cutting blade, when the protection device is not interrupted, by actuating the manual control; and stopping the cutting blade which is being lowered when the protection device is interrupted. Immediately after stopping the cutting blade which is being lowered, the drive motor is operated to reverse the cutting blade under safety monitoring into a nondangerous upper safety location.
