A pipe cap and methods for using the pipe cap are provided. The invention includes a pipe cap, which can include a body having one or more openings disposed therein. The pipe cap can also include a connector, and the connector can be configured to connect to a drain pipe. The pipe cap can be configured to prevent insects and animals from entering and clogging fluid drainage systems, e.g., HVAC systems.

The grinding device is for removing a collapsed liner inside a pipe. The grinding device has a connector for a drive shaft, a body rotatable around a rotation axis with the drive shaft and grinding cutters attached to the body. The grinding cutters have cutting edges provided in a plane perpendicular to the rotation axis of the body and the grinding device further has an outer periphery isolated from rotation of the body by bearings.

A sealing element for pipes comprises a body made up of a section of stem that has a circular plant head region at one end that acts as a grip area. The stem section includes in a downward direction from the head region a plurality of parallel positioning regions with a substantially discoidal shape, having a primary positioning region that has a larger diameter than remaining secondary positioning regions. The primary positioning region has two sections devoid of material diametrically opposed to each other, so as to define two opposite fins capable of bending. A positioning region adjacent to the primary positioning region in a direction to head region has two sections devoid of material which are offset by 90 degrees with respect to the positioning of the two sections devoid of material of the region of primary positioning.

A locking assembly for a door assembly of an agricultural vehicle includes: an actuator that defines an actuator axis and is linearly movable between a first position and a second position and rotatable about the actuator axis between a first locking orientation and a second locking orientation and includes a pair of locking features; a biaser configured to bias the actuator toward the first position; an energizer configured to bias the actuator toward the first locking orientation when the actuator is in the second locking orientation; and a lock configured to engage a second locking feature when the actuator is in the second locking orientation. Linear movement of the actuator from the first position to the second position while the actuator is in the second locking orientation causes the lock to disengage from the second locking feature so the energizer rotates the actuator towards the first locking orientation.

A diffuser basket includes a screen portion and a flow modifier positioned within the screen portion. The flow modifier is configured to change the direction of flow of a fluid introduced into the diffuser basket. The flow modifier can include a plurality of flat plates coupled to the screen portion and positioned at spaced apart intervals along a longitudinal axis of the diffuser basket. The flow modifier can include a plurality of truncated conical plates positioned at spaced apart intervals along a longitudinal axis of the diffuser basket, the plurality of truncated conical plates coupled to the screen portion. The plurality of flat or truncated conical plates each can include an opening. The plurality of flat truncated conical plates each has a cone angle that forms an oblique angle with respect to the longitudinal axis. These cone angles can be the same or they can be different.

A pipeline strainer having a body with a straining element therein. An air release valve may be disposed in the body so that any accumulated entrained gas may be vented. A baffle may be disposed downstream of the straining element and used to accumulate entrained gas in an eddy. The baffle may include or comprise a coalescing material. The pipeline strainer may have a Y-shaped body or may comprise a basket strainer.
