A firearm including a barrel having a breech and a muzzle defining a length of the barrel is disclosed. The firearm includes a hand guard having a first end and a second end with a front sight is attached to at least one of the barrel adjacent the muzzle and the second end of the hand guard. A housing is coupled to the front sight and defines a chamber having a piston disposed therein and movable between static and displaced positions. A receiver is coupled to the first end and a bolt carrier is disposed within the receiver and moveable between firing and rearward positions. A carrier key is attached to the bolt carrier and moves concurrently with the bolt carrier and a rod is permanently affixed to the carrier key and extends to a distal end with the piston engaging the distal end when moving to the displaced position.

A firearm includes a receiver and a barrel connected to the receiver. A hand guard extends from the receiver and defines a hand guard bore. The receiver includes a threaded end and the hand guard includes a flange extending into the hand guard bore and abutting the receiver about the threaded end. A hand guard nut abuts the flange of the hand guard and threadedly engaging the threaded end of the receiver. The hand guard nut sandwiches the flange between the hand guard nut and the receiver for attaching the hand guard to the receiver. The hand guard includes a first hand guard portion and a second hand guard portion removably attached to the first hand guard portion. The second hand guard portion is slid from an assembled position to a disassembled position to expose the hand guard nut in the hand guard bore.

A movable barrier apparatus, a kit configured to be assembled and mounted adjacent to a barrier opening, and a method of monitoring for ballooning of a movable barrier are described herein. A sensing device is positioned outwardly from a drum configured to receive a movable barrier therearound. A ballooning movable barrier engages or disturbs the sensing device, which, in response to the disturbance, sends a signal, such as a signal to sound an alarm, stop movement of the door, or the like.

A firearm includes a receiver and a bolt carrier disposed in the receiver. The bolt carrier is moveable between a firing position and a rearward position. A rod is fixed relative to the bolt carrier and a hand guard is coupled to the receiver about the rod. A handle assembly is slideably supported by the hand guard and is moveable toward the receiver to define a charging motion and away from the receiver to define a forward assist motion. The handle assembly receives the rod during both of the charging and forward assist motions. An arm is coupled to the base and is moveable between a disengaged position spaced from the rod and an engaged position abutting the rod. When the arm is in the engaged position, the handle assembly is moved to move the rod and the bolt carrier in either of the charging and the forward assist motions.

A firearm having a receiver defining a bore with the receiver extending along a longitudinal axis. The receiver defines an ejection port transverse to the longitudinal axis with the bore defining an inner surface. A bolt carrier is disposed in the bore and moves relative to the receiver along the longitudinal axis between a firing position and a rearward position with the bolt carrier defining at least one exhaust port transverse to the longitudinal axis. A shield defines an aperture aligned with the exhaust port for exhausting gases therethrough. The shield is longitudinally affixed to the bolt carrier and moves with the bolt carrier as a unit between the firing and rearward positions along the longitudinal axis with the shield blocking the ejection port when in the firing position and the shield sliding along the inner surface away from the ejection port when moving to the rearward position in conjunction with the bolt carrier.

A filling machine assembly having supports for supporting any suitable fixture. At least one of the supports includes a plurality of modules with each of the modules including at least one coupling member for interlocking adjoining modules to form a continuous uninterrupted support. The modules can include sides with at least one coupling member mounted to each side. The coupling members are preferably complementary in configuration with each other for interlocking the first and second modules.

A filling valve apparatus for filling a container with a fluid. The apparatus includes a body portion and a stem. A sleeve is disposed over the stem and is removable from the stem and the body portion when the filling valve apparatus is serviced. A seal is mounted to the bottom of the sleeve. At least one component is movably connected to the sleeve and remains connected to the sleeve when the sleeve is removed from the stem and the body portion during the servicing of the filling valve apparatus. Similarly, a valve assembly, having a housing and a movable plunger is removable from the body portion. At least one member is mechanically connected to one of the housing and plunger for creating a unitary valve assembly that remains intact when the valve assembly is removed from the body portion during servicing of the filling valve apparatus.

A capping device fits caps onto containers by applying an axial force to the caps as they are threaded onto the containers. The capping device utilizes a spindle rotatable about an operational axis for imparting rotation to a capper unit. A connector coupled to the capper unit is releasably coupled to the spindle by a quick release mechanism. The quick release mechanism is normally biased in the locked position and is configured to automatically move from the unlocked position back to the locked position when the connector mates with the spindle as a user re-connects the capping unit back to the spindle. Methods of releasing and re-connecting the capping unit to the spindle are also disclosed.

A device is provided for interconnecting a support and a connector through a quick release mechanism. The quick release mechanism is normally biased in the locked position and is configured to automatically move from the unlocked position back to the locked position when the connector mates with the support as a user re-connects the unit back to the support. Methods of releasing and re-connecting the unit to the support are also disclosed.

A package wrapping removal system and method of operation for removing a wrapping from a product has a first cutter that cuts the wrapping along a first side face of the wrapped product as the product moves along a first transport. A second transport of the system then receives the wrapped product from the first transport. As the wrapped product moves along the second transport, the first cutter and an opposing second cutter cut the wrapping along respective flanking side faces of the product. A vacuum device integrated into the second transport then removes the wrapping as one piece as the unwrapped product continues to move downstream.
