A rotary cutter head includes a rotary body, resilient clamping arm, and at least one cutting blade. The clamping arm clamps the cutting blade radially inwardly first rather than in a circumferential direction in order to positively lock the cutting blade radially, and thereby prevent the cutting blade from migrating out of position slightly during high speed rotation of the cutter head.

An apparatus and system for minimizing the risk that a cognitively impaired individual will wander or elope, and for locating the individual in case he or she nonetheless successfully wanders or elopes. The system employs a wearable appliance which the cognitively impaired individual should not be able to remove easily. The system also employs a smartphone having an application for use by a care giver. A website and cloud server are employed for communication of data from the wearable appliance to the smartphone and from the smartphone to the website. In an optional embodiment, the smartphone can initiate notifications to other smartphones held by other individuals who can assist in the search.

In an open-end spinning device (1) of a rotor spinning machine (2) having a spinning rotor (3) with a rotor cup (4), in which fiber material (6) can be spun, and with a rotor shaft (5) through which the spinning rotor (1) can be driven, and a bearing (13) preferably arranged in a contactless way, with a drive, especially an individual drive (14), to drive the spinning rotor (3), with a rotor housing (15), in which the rotor cup (4) of the spinning rotor (3) is arranged and which is impinged with spinning negative pressure (pSU) during spinning operation through a negative pressure channel (16) of the open-end spinning device (1), and with a drive housing (17), in which the rotor shaft of the spinning rotor extends, and in which the drive and the bearing (13) of the spinning rotors are arranged, the rotor housing (15) and the drive housing (17); are arranged spaced apart from one another in the open-end spinning device (1) in axial direction of the rotor shaft (5). In a corresponding method to operate such an open-end spinning device (1) of a rotor spinning machine (2), the rotor housing (15) is impinged with spinning negative pressure (pSU) during the spinning operation. Air current is prevented from flowing from the rotor housing (15) into the drive housing (17) by arranging the rotor housing (15) and the drive housing (17) spaced apart from one another in the open-end spinning device (1) in an axial direction of the rotor shaft (5).

An apparatus and method for use in the initial positioning, guiding, clamping and removal of a tubular casing used to produce a borehole, including a mainframe with an opening configured to receive, clamp onto and centralize the casing within the mainframe opening.

New forms of towels, mats, tarps and other ground-covering sheets, and other devices, systems and methods providing protection from sand, dust, debris, and fluids are provided. In some aspects of the invention, ground covering sheets with an inherent guard, partially around a periphery of the sheets, are provided. In several embodiments, specialized ground-covering sheets are provided with reinforced, specialized sections configured to receive and hold legs, ground stakes and / or other parts related to structures to be mounted in, on or about such ground-covering sheets. In some such embodiments, such reinforced, specialized sections include a matrix of expandable receiving brackets, through which the support legs, ground stakes and / or other parts can penetrate, and reach and obtain direct support from the ground below such ground-covering sheets.
