Embodiments are directed to methods and apparatuses for ensuring that mechanisms that are used to position components of an apheresis machine are not broken as a result of rotation of a centrifuge. In embodiments, a safety mechanism is provided that contacts components of the centrifuge and pushes them into a position to ensure that they do not break when the centrifuge is operated at high rpm.

In an example, the solar tracker has a clamp assembly configured to pivot a torque tube. In an example, the assembly has a support structure configured as a frame having configured by a first and second anchoring region. In an example, the support structure is configured from a thickness of metal material. In an example, the support structure is configured in an upright manner, and has a major plane region. In an example, the assembly has a pivot device configured on the support structure, a torque tube suspending on the pivot device and aligned within an opening of the support, and configured to be normal to the plane region. In an example, the torque tube is configured on the pivot device to move about an arc in a first direction or in a second direction such that the first direction is in a direction opposite to the second direction.

A modular comb system and method can include: a frame including a comb body; a locking ring including a locking mechanism for mating with the comb body and for locking the locking ring to the comb body; and a screen insert configured to be in a fixed position with respect to the frame based on the locking ring being locked to the comb body.

An anchor for lightning protection systems includes a base and pad that extend over a sufficient area and a sufficient bearing length to hold in shear and in tension against the weight, shear force, and moment of cables, points, and other components of a lightning protection systems. A universal point mount may be forged to optimize cross sectional area and contact surface area throughout the mounting system. Drilled and tapped to receive a point oriented arbitrarily, the head mounts easily on a horizontal or vertical mounting surface. Apertures and fasteners provide arbitrary positioning of a point at any necessary orientation.

A tool for removing a coating from an end of a coated conduit comprising a metallic conduit having an outer diameter and a polymeric material applied over the outer diameter thereof is provided. The tool comprises: a guide member having an outer diameter sized to fit within an internal diameter of the metallic conduit; and a cylindrical cutting member having a substantially closed first end rotatably connected to an arbor, a substantially open second end, and a plurality of teeth elements. The cylindrical cutting member has an inner diameter that is substantially equal to the outer diameter of the metallic conduit such that when the cylindrical cutting member is rotated, the teeth elements remove the polymeric material from the outer diameter of the metallic conduit.

A hybrid medical device that can aid in reconstructive or augmentative surgery of the breast is disclosed. The device can utilize a suitable biological collagen tissue matrix combined with a synthetic material, for example, that can impart a high initial strength to the repair site while permitting proper healing and revitalization of the implanted device.

A securement apparatus for a portable electronic device including a body having a panel and a plurality of elastomeric retainers secured to and extending from the panel. Each retainer forming a loop defining an opening, the openings adapted to receive therein a corner of a handheld electronic device. A tether is connected to and extending from the body. A strap is secured to the tether. An attachment device is operably connected to the strap to secure the apparatus to a member.

A connector system facilitates the connection of a first tree trunk to a second tree trunk of an artificial tree system. The connector system can prohibit rotation of the first tree trunk relative to the second tree trunk.

Exemplary embodiments are disclosed of liners, linings, and liquid containment vessels including the same. Also disclosed are exemplary method of providing liners and linings for liquid containment vessels, such as process tanks, immersion tanks, containment pits, gravity feed conduits for transferring or conveying liquid, etc. In an exemplary embodiment, a liner or lining is anchored to at least one structural component by at least one extrusion weld and at least one mechanical fastener. The mechanical fastener is coupled to the structural component. The extrusion weld is coupled to the mechanical fastener. The liner or lining may be anchored to a wide range of structural components, such as a frame, a framework, a frame member, a tank, a wall, a support member, a reinforcing member, an outer shell, a substrate (e.g., concrete, etc.) or sidewalls defining a pit or a gravity feed conduit, combinations thereof, other structures or components, etc.

An apparatus (10) includes a fastener (16) engageable with a bone portion to connect a longitudinal member (12) to the bone portion. A housing (40) has a first passage (42) configured to receive the longitudinal member (12) and a second passage (44) extending transverse to the first passage. The fastener (16) extends through an opening (50) in the housing (40) into the second passage (44). A longitudinal axis (18) of the fastener (16) is positionable in any one of a plurality of angular positions relative to a longitudinal axis (46) of the second passage (44). A spacer (60) received in the second passage (44) of the housing (40) is engageable with the fastener (16) and the longitudinal member (12). A member (70) applies a force to prevent relative movement between the fastener (16) and the housing (40) and permit manual movement of the fastener (16) relative to the housing (40) against the force when the longitudinal member (12) is disengaged from the spacer (60). A clamping mechanism (90) clamps the longitudinal member (12), the spacer (60), and the housing (40) to the fastener (16) to prevent movement of the fastener relative to the housing.
