Abstract: A selective fire firearm may be provided having a fully automatic open bolt and a semi-automatic closed bolt mode of operation. The firearm may include a trigger group having a trigger prop that ensures that, when the trigger is released in the fully automatic open bolt mode, the bolt carrier stops in an open bolt position held by an open bolt sear. The trigger prop may include a foot that, following a first trigger pull in the fully automatic open bolt mode, slides under and props a rear end of the trigger in a position that allows the open bolt sear to catch the bolt carrier when the trigger is released and propped but prevents the trigger sear from engaging the hammer.

Abstract: A centrifugal pump pet water fountain is provided which includes a bowl defined by a peripheral wall extending upwardly from a floor. The bowl is configured to hold water. The housing divides the basin into a drinking basin and an interior basin. The housing includes an upright sidewall extending from a floor and a cap. The housing also defines an elevated water reservoir with a spout. A rotating cone is positioned within the housing and driven by a motor. The cone has a water inlet and a top opening adjacent the cone top opening. During operation, the rotation of the cone forces water to climb the interior surface of the cone through centrifugal force, where the water is deposited within the reservoir and returned to the drinking basin through the spout.

Abstract: A trigger assembly includes a trigger, a transfer bar having a distal end and a proximal end, the distal end of the transfer bar being coupled to the trigger and the proximal end having a step defined therein; and a sear configured to selectively engage the proximal end of the transfer bar.

Abstract: An intermittent ignition device for use with a furnace includes a pilot assembly configured for installation in the furnace and a gas valve configured for installation in the furnace to selectively supply gas to the pilot assembly and a burner assembly of the furnace. The intermittent ignition device further includes an ignition control module that transmits signals to the pilot assembly and the gas valve. The intermittent ignition device further includes a power source positioned outside of the furnace that supplies power to the ignition control module and the gas valve.

Abstract: A pet door is provided herein. The pet door includes a pivotal flap and a frame that defines a through-way. A rotatable knob is mounted to the frame and has a handle portion and a stop wall. The handle portion and stop wall include various profiles and configurations that work in concert to control the flap's direction of pivotal movement. In a first configuration, the flap may swing outwardly or inwardly. A second configuration prevents the flap from swinging inwardly. A third configuration prevents the flap from swinging outwardly. A fourth configuration places the flap is in a locked position to prevent swinging in either direction. The electronic door also includes an electronic latch mechanism which selectively latches and unlatches the flap. The latch mechanism unlatches the flap in response to a wireless signal from an electronic transmitter that may be affixed to a pet.

Abstract: A firearm includes a receiver body is provided herein having a plurality of barrel-tightening portions with at least one relief recess therebetween and relief recesses defined in the body on either proximal end. The relief recesses and barrel-tightening portions are sized to allow the barrel-tightening portions to be tightened and loosened independently of each other. A barrel assembly is removably coupled to the receiver body.

Abstract: In one example, a fluid system is provided that includes an air-operated fluid pump, a control air system operably connected with the fluid pump, and a pump controller operably connected with one or more components of the control air system. The pump controller is configured to automatically control the operation of the air-operated fluid pump by way of the control air system. The fluid pump parameters automatically controlled by the pump controller can include a discharge flow rate of the fluid pump, a discharge pressure of the fluid pump, and/or a pulsation value associated with the discharge of the fluid pump.

Abstract: A storage system stores objects and copies of objects on the storage system and other storage systems external to the storage system. The storage system stores the copies in storage pools of volumes, which are organized into one or more tiers. The configuration settings of each tier and each pool within the tier may be configured according to a user's preferences. In one example, the number of copies of data content and the number copies of metadata associated with the data content an individual pool stores may be specified. When objects are migrated between tiers, the objects are stored among the storage pools of the tiers. If the number of data content copies or metadata copies is increased, the data or metadata is copied from a determined copy source and if the number of copies decreases, the data is removed from the volumes in the pools.
