  • Publication number: 20190242663
    Abstract: A firearm gas piston system provides tool-less removal and adjustment of gas flow along a nonlinear gradient and directs exhaust discharge away from the operator. The system includes a gas block with gas channels for directing exhaust gas away from an operator and a gas plug bore configured to accommodate insertion of a gas plug. The gas plug can include an actuator for rotating the gas plug, a key that fits within a key notch and key channel inside the gas plug bore to secure the gas plug within the bore, and a regulator portion to control the flow of discharge gas from a firearm barrel. The regulator portion includes a passage with two opening segments that accept discharge gas from the barrel and direct the gas through another opening disposed in a regulator cutout and to a piston portion of the gas block.

  • Patent number: 5636575
    Abstract: A retarder apparatus controls the speed of a free, load-carrying conveyor as it moves in a predetermined direction along a path of travel defined by the track in which the conveyor runs. Paddle members are spaced at regular intervals along an endless movable chain and each, in turn, is positioned in the track in the path of the next conveyor. Upon engagement of an individual paddle by an oncoming conveyor, the chain is instantly accelerated to the speed of the conveyor and this motion is transmitted through a chain sprocket to a centrifugal brake which, if a normal speed is being exceeded, limits the speed of movement of the chain to hold back a runaway conveyor and return it to the normal speed.

  • Patent number: 5511486
    Abstract: The trailing, load supporting component of a product conveyor is connected to a powered, leading component by a shock absorbing tow bar that employs a dampener tube in which a plunger moves against the resistance of a sleeve of resilient material. The head of the plunger is oversized with respect to a passageway defined by the sleeve and thus is forced to compress and displace the resilient material in order to move relative to the passageway in response to an impact caused by rapid acceleration or deceleration of the conveyor. Compression and displacement of the material occurs at a zone of contact of the head with the material, the head shifting the zone of contact and compressing and displacing the material in response to the impact communicated to the tow bar. A protective sleeve shields an exposed plunger rod from contaminants and enhances the structural integrity of the assembly.
