Abstract: In various embodiments, an oven includes a cooking chamber floor including a ceramic blanket; and walls, the walls and cooking chamber floor defining a cooking chamber. In various embodiments, an oven includes walls including a panel; and a frame including an extruded corner post, the extruded corner post including an inner wall and an outer wall defining a channel, a portion of the panel positioned in the channel of the extruded corner post.

Abstract: A device for arresting spark and ash issuing from, and precisely controlling the ventilation of and temperature inside, a heat source-containing vessel such as a cooking grill, stove, oven, cooker, fireplace, heater, or firebox. The device comprises a spark arrestor assembly including a base plate, a cover plate, and a spark arrestor. The base plate defines an opening. The cover plate and spark arrestor are slidably mated in two channels formed in the base plate around the opening. The cover plate and spark arrestor may be adjusted to extend across or only partway across the opening as selected by a user of the device. Tabs are provided on the cover plate and spark arrestor for easy adjustment thereof. Tabs in the base plate are positioned to define a range of slidable motion of the cover plate and spark arrestor.

Abstract: A system for providing access to a fire hydrant. The system includes an actuator extension having a first end and a second end spaced from the first end. The first end is configured to be mounted on an exterior location on the fire hydrant, so that the first end is operatively engaged with a valve actuator of the fire hydrant, the valve actuator being selectively rotatable to cause a valve of the fire hydrant to open and close. The second end is spaced from the first end and is configured to facilitate application of an externally-applied force and transmission of such force to the first end of the actuator extension.
