A photovoltaic (PV) module framing and coupling system enables the attachment of PV modules to a roof or other mounting surface without requiring the use of separate structural support members which attach directly to and span between multiple PV modules in a formed PV array. The apparatus provides a parallel coupling for securely interlocking the outside surfaces of parallel frame members together in a side to side arrangement to form an array with improved structural load distribution. The coupling may attach to a slot in the frame at substantially any position along the length of the frame thereby enabling the interconnection of adjacent PV modules along both an x and y axis. The apparatus may further provide a rotating portion and locking portion, mounting brackets for direct connection to a mounting surface, grounding teeth, and a twist-lock engagement means for interlocking and aligning PV modules in the array.

A minimally invasive and open surgery surgical system for implanting spinal screw assemblies to be connected by a spinal rod is disclosed. In one form, the system includes an improved tool device for inserting a cap insert into an initial and final locking of a screw assembly and securing a spinal rod inserted through an incision to a vertebra. In another form, the system also includes a screw fixation system that allows greater variability in thread diameter for orthopedic implant for in the spine, iliac crest, or bones.

A protective mask adapted to be worn by persons engaging in physical games comprises a body formed of rigid plastic material including a nose portion, a chin portion, a brow portion, opposite cheek portions and opposite side temple portions; an opening is provided between the brow portion and the nose portion and cheek portions to be covered by a flexible transparent lens. A throat guard is pivotally mounted to the opposite cheek portions and extends inwardly of the chin and cheek portions; the throat guard is pivotal between two vertical positions relative to the chin and cheek portions and includes a tongue that extends towards the inner face of the mask and is adapted to contact an inner lower edge area of the mask to define the lowermost vertical position; the throat guard further includes a lower outwardly projecting area to contact the lower edge of the mask to define the uppermost vertical position for the throat guard.

An arbor for quick change and standard hole cutters, wherein each hole cutter includes a central aperture and at least one drive pin aperture. The arbor comprises an arbor body including an end portion engageable within the central aperture, a drive shank opposite the end portion for engaging a power tool, and an aperture for receiving a pilot bit. The arbor further comprises a drive pin plate and/or collar having at least one drive pin receivable in a corresponding drive pin aperture of the hole saw for drivingly engaging the hole saw. The arbor, in at least one embodiment, further comprises a pilot bit mechanism for engaging and releasing a quick change or standard pilot bit.

Provided is a cartridge assembly having first and second cartridges sealed by an interface member having a first sealing member along a radially outer surface thereof having a non-planar geometry around the outer surface and a second sealing member along the radially outer surface having a non-planar geometry around the outer surface. The sealing members may each have a repeating, undulating, non-planar geometry around the outer surface. The cartridges have ends with matching geometries to allow the cartridges to engage in surface-to-surface relation around their entire extents to create with the interface member an air tight seal.

A hydrodynamic clutch device includes a clutch housing connected to a drive, a pump wheel connected to the clutch housing, and a turbine wheel connected to a takeoff, the turbine wheel and the pump wheel forming a hydrodynamic circuit. A bridging clutch which is essentially surrounded by the hydrodynamic circuit includes a piston and at least one friction surface which can be acted on by the piston to connect the drive to the takeoff independently of the hydrodynamic circuit, the piston having one surface facing the hydrodynamic circuit and an opposite surface facing a pressure space. A pressure circuit includes a first pressure medium line to supply the hydrodynamic circuit with clutch fluid and a second pressure medium line to supply the pressure space with clutch fluid. A seal at least reduces the exchange of fluid between the hydrodynamic circuit and the pressure space, and a throttle allows a defined exchange of fluid between the hydrodynamic circuit and the pressure space.

A personal respiratory protection device 10 that comprises a mask body 12 that has a structure 35 located on it for receiving a clean air supply source such as a filter cartridge 14. The clean air receiving structure 35 has a first threaded portion 34. The clean air supply source has a second threaded portion 58 that has a thread 60 that mates with a thread 36 of the first threaded portion 34. The first and second threaded portions 34 and 58 engage each other at a high thread pitch and include an integral détente. A stop prevents over-rotation of the clean air supply source 14 relative to the mask body 12 during the securement operation. The inventive device allows the clean air supply source 14 to be attached to the mask body 12 with minimal rotation and is sufficiently intuitive that users may only need one hand to attach and replace the clean air source component 14 without having to remove the respirator 10 from their face.

A filter module includes a filter element with a ring of media and an end cap at one end of the ring. The end cap includes an annular body with a sealing member located around a surface of the body circumscribing a central opening, wherein the sealing member has a repeating, undulating, non-planar geometry. The axial, distal end of the annular body also has an repeating, undulating non-planar geometry, matching the geometry of the sealing member, and can have one or more tabs projecting axially outward from the distal end, positioned at a point of maximum amplitude of the distal end, and which are received in cooperating slots formed in a socket of a diaphragm, to facilitate positioning and installing the element into the module. The socket includes an outer wall having a matching non-planar geometry which receives and seals against the sealing member on the end cap.
