Abstract: A sealing device for sealing between two relatively rotating cylindrical surfaces in a conveyor has its one cylindrical surface formed as a stationary wall portion in a transition housing and its other cylindrical surface formed as a cylindrical wall portion of a rotating bottom in said transition housing, one of said cylindrical surfaces being provided with at least one scraper and/or impeller blade acting against the other of said cylindrical surfaces in order to feed material, during operation, in a direction into the interior of the conveyor, thereby to reduce the tendency of the bulk goods to penetrate between and cause wear of said two cylindrical surfaces.

Abstract: A supporting table for a recumbent patient has a table plate provided at least along the side edges, and preferably also at the head and foot edges, with a gate member which is pivotally mounted so that it can be fixed in an up position. In this position the gate members not only keep a patient from rolling off the table but they cooperate with a mattress on the table to form a trough in which water may be retained for bathing the patient. The mattress has an outlet for discharging the water after bathing. In the down position of the gate members the mattress edges are also folded downwardly.
