Abstract: This invention relates to a process for the biological purification of wastewater in at least two immediately successive treatment stages, followed by a post clarification stage wherein the process is adapted so that a wastewater-activated sludge mixture in one of the treatment zones exhibits only a minor biological load and a nitrification process is conducted therein. In accordance with the invention, an intermediate clarification tank is not required due to substantially all biological degradation having occurred in the stage immediately before the nitrification stage. To enhance nitrification a macroporous carrier material for supporting nitrifying bacteria, for example, activated carbon or polyurethane foam, is added into this nitrification treatment stage. The material can be readily retained in the nitrification zone by providing appropriate retaining means. This process offers the advantage that the concentration of nitrifying agents, i.e., bacteria necessary for nitrification is maintained at the required level at all times. In another aspect, the invention relates to the apparatus for carrying out the process.

Abstract: A gingival retraction cord having improved characteristics is constructed by a knitting process. Because of the presence of numerous interlocking loops, the knitted retraction cord is longitudinally elastic, thereby avoiding the tendency to become dislodged once packed as additional portions of the cord are packed around the margin of a tooth. The knitted retraction cord is also transversely resilient, thereby tending to better conform to the gingival sulcus.

Abstract: Apparatus for recording and reproducing audio signals on flat rectangular recording media comprising a magnetic coating or the like on at least one side. A magnetic head on a swing arm moves across the magnetic media in mutually parallel lines guided by a heart-shaped cam, the recording medium being stationary during recording and reproducing so its visible surface can be examined without difficulty. The heart-shaped cam is of asymmetric configuration, and the magnetic head is pivotably mounted on one end of the swing arm which carries between its ends a cam follower peg which continually engages the heart-shaped cam while under spring loading. The other end of said swing arm is pivotably mounted on a sliding carriage plate which is moved stepwise perpendicularly to the chord of the curved path of movement of the magnetic head for each line. The stepwise perpendicular movement of the sliding carriage plate is produced by a mechanism which is controlled by the reversal of direction of the magnetic head.

In one version of the invention there is a moveable fourth gear (82) in meshing engagement with the third gear (70) and driven thereby. The fourth gear (82) can be swung from a first position where it is in meshing engagement with the second gear (66) to a second position where it is in meshing engagement with the drive gear. A chain loop (46) connectable to the door is driven when the second gear and the idler roller rotate and it is provided to close the door even under pressure. In a second version, a floating clutch drive system employing an endless chain is employed to selectively drive either the shaft about which the door is rolled or the chain loop.
