Abstract: Water testing apparatuses and methods for detecting contaminants in water supplies, such as from wells or other domestic water sources. The apparatuses are for use in reservoirs, such as a water closet of a sanitary toilet. They include an enclosure which defines an interior chamber which is intermittently charged with water. The water charged to the interior chamber is passed through one or more filters, preferably a packed column, which removes or otherwise indicates the presence of contaminants in the water. A counter measures the water passed through the system. Water is discharged from the interior chamber using a siphon. The siphon and restriction of flow caused by the filters help control the direction of flow and substantially prevent backflow. The summit of the siphon includes a relief valve for venting gas during filling of the siphon discharge.

Abstract: Brick courses are successively lifted and transferred from a kiln car onto the receiving end of a marshalling table with the longitudinal dimension of bricks extending transversely of the table. A push mechanism pushes against the cut surface of the bricks and moves the bricks longitudinally of the table toward the discharge end thereof, urging the bricks against an upstanding wall of a movable, marshalling carriage. The carriage slides from a first position beneath the discharge end of the marshalling table to a second position beyond the discharge end in response to the pressure exerted by the push mechanism. When a prescribed number of bricks have been pushed against the upstanding wall and the movable carriage moved to its second position, the push mechanism is deactivated and a clamp engages and holds the bricks remaining on the marshalling table. The marshalling carriage is then moved an additional distance to space the bricks thereon from the bricks remaining on the marshalling table.
