A navigable probe system and method of use is provided. The system may include a handle assembly having a locking mechanism enclosed and a stylus, a cannula, and a tracking device extending from the handle assembly. The stylus may include undercuts for receiving pins of the locking mechanism. A cam of the handle assembly may rotate such that in a first position, the pins of the locking mechanism may be engaged with the undercuts and in a second position, the pins of the locking mechanism may be disengaged from the undercuts releasing the stylus from the locking mechanism. The stylus may be slidably engaged with an inner diameter of the cannula. In some arrangements, the handle assembly may include a quick connect system that in a first position attaches the cannula to the handle assembly and in a second position releases the handle assembly and thus stylus from the cannula.

A filter cartridge includes a media pack having first and second opposite flow faces; the media pack comprising flutes extending in a direction between the inlet flow face and the outlet flow face; a frame mounted on the second flow face of the media pack; a seal support section extending from the base member; and first and second opposite and spaced blades extending from the base member and in a different direction from the base member as the seal support section. The first and second blades are embedded within the media pack through the second flow face. A seal member is oriented against the seal support section. The filter cartridge can be removably oriented in a cassette. The cassette and filter cartridge are removably oriented in an air cleaner housing. The cassette may include lugs to help position the cartridge in sealing engagement with the air cleaner housing. In another embodiment, the filter cartridge is cassette-free and includes a cartridge-handle projecting therefrom.

A viscous clutch head may be replaced by selecting a viscous clutch head and a mount adapter. The viscous clutch head and the mount adapter may be selected from a group of universal modular fan drives and from a group of mount adapters. The mount adapter of a threaded type or a flange and bolt type may be selected. Depending on the viscous clutch head to be replaced, a fan adapter and/or a pilot adapter may also be selected from a group of fan adapters and from a group of pilot adapters. Accordingly, a range of models of viscous fan clutch systems may be replaced by using a limited number of parts. These parts may be stored on a tool cart. As different models of viscous fan clutch systems may be replaced using a limited number of parts, the in-stock inventory of replacement parts may be reduced.

An air cleaner arrangement or assembly is provided. The air cleaner arrangement includes a serviceable filter cartridge. The air cleaner assembly also includes an arrangement for positioning the filter cartridge into a preferred, sealing, orientation and for securing the filter cartridge in that location. Preferred serviceable filter cartridges are provided, as well as methods of assembly and use.

A method for replacing a tag tool needle includes securing at least a portion of a tag tool needle coupled to a tag tool in a needle container; and removing the tag tool needle from the tag tool with the needle container. A tag tool needle container includes a first tubular aperture adapted to receive at least a portion of a first tag tool needle therein, where the first tubular aperture has a compression-fit adapted to securely enclose the portion of the first tag tool needle when urged over the first tag tool needle; and a second tubular aperture coupled to the first tubular aperture and adapted to receive at least a portion of a second tag tool needle therein, where the second tubular aperture has a compression-fit adapted to adapted to securely enclose the portion of the second tag tool needle when urged over the second tag tool needle.

An improved hand tool for dispensing plastic fasteners having a novel anvil design and a needle. The hand tool has a gun shaped casing with a barrel portion and a handle portion. The casing has a needle assembly opening at the front of the barrel portion and a trigger slot at the front of the handle portion. The hand tool further has a hollow needle disposed on one end of a needle assembly. The hand tool further has a trigger that is pivotally mounted within the casing that extends out from the trigger slot. The hand tool further has an anvil.

A knife is provided that includes a replaceable blade element. The knife employs a blade carrier that is fixedly interconnected to or foldable with respect to a handle. The blade carrier selectively receives the replaceable blade element that is locked into the blade carrier by way of a hook and movable pin combination. The replaceable blade element is designed to be inserted within the blade carrier quickly, easily, and safely.

Pipe splitting apparatuses and systems including a replaceable blade, and methods therefor, are provided. In various examples, a pipe splitting apparatus includes an outer surface including a recess. A blade including a portion is disposed within the recess. A hardenable material is disposed within the recess. The hardenable material is configured to flow upon application to fill empty space within the recess and at least partially around the portion of the blade disposed within the recess. The hardenable material is further configured to harden after application to secure the portion of the blade within the recess and fix the blade to the pipe splitting apparatus.

A half facepiece respirator has a shaped support piece supporting and fixing the position of a particle or paper filter insert or outsert with either the support piece or the particle filter incorporating a face sealing component. Placed within the shaped support piece, a grille may be placed in the lower section of the shaped support piece. Additionally the half facepiece includes a head harness having a release mechanism.

A filter assembly includes a canister housing closable by a lid and containing a removable and replaceable filter element cartridge. The lid is part of the filter element cartridge and a single unitary component therewith, such that removal of the filter element cartridge also removes the lid, and replacement of the filter element cartridge also replaces the lid.
