Abstract: A retainer ring connector comprised of a ring situated between matching spokes on both the male and female members of a hose coupling. The ring is contained behind the outwardly extending spokes on the male member. When the male member is inserted into the female member, spokes on the inside of the female member pass between the spokes of the male member and are forced over the ring element which compresses sufficiently to allow the spokes to pass. After the spokes of the female member pass over the compressed ring member, the ring member expands and prevents the male and female members from disengaging and backing away from each other. The spoked retainer ring connector allows for complete rotational movement with preventing the male and female members from separating.

Abstract: A handle for a mop or other such cleaning instrument is hollow for flow of water from a hose attached to one end of the handle to the work-engaging portion at the other end. A manually operable control moves a stopper between three positions wherein flow through an opening in an internal partition in the handle is fully blocked, partially blocked or fully unblocked. The stopper has a total of three detent members in the form of rounded protrusions and a total of three recess for receiving the detents are formed in the partition. As the operating member is manipulated to move the stopper between its three positions, one detent engages a recess in the fully blocked position, two detents engage respective recesses in the partially blocked position and all three detents engage the three recesses in the fully unblocking position. The provision of three detents and three recesses adds to the stability and reliability of operation of the implement.

Abstract: A sudser unit having an entry port, discharge port, and a fluid conduit. The discharge port and fluid conduit extend along a common longitudinal axis, and the entry port extends along a longitudinal axis that intersects the longitudinal axis of the discharge port and fluid conduit at an oblique angle. A water supply, such as a hose, is operably connected to the entry port. A converging nozzle having an opening of smaller diameter than that of the entry port is attached to the discharge port, and a detergent reservoir is attached to the fluid conduit. A valve is disposed between the reservoir and fluid conduit. A valve is disposed between the reservoir and fluid conduit to permit selective mixing of the water and detergent, and selective metering of the mixed composition.

Abstract: The invention provides a method and apparatus for efficiently regenerating an incoming data signal at a sampling point which is continually optimized independently of the regeneration process. While the incoming data signal is being regenerated in a regeneration unit, the invention uses a monitoring unit for concurrently optimizing the slicing threshold and sampling phase used in the regeneration unit without disturbing the on-going data regeneration. The invention uses a master-slave arrangement to regenerate the incoming data signal whereby the regenerating unit is updated with a new slicing threshold and sampling phase only after the new slicing threshold and sampling phase are fully optimized by the monitoring unit. In this way, the data regeneration can proceed unaffected by the optimization of the slicing threshold and sampling phase which, as a result can be continuously optimized without inducing any errors into the regenerated data.

Abstract: A clock extraction circuit for retiming a ternary data stream derives first and second binary streams corresponding respectively to the positive and negative going portions of the ternary data stream These binary streams are combined to provide a further binary stream which is retimed to a local clock whereby to generate a reference stream for retiming the first and second binary data streams to said reference stream. The retimed binary data streams are combined to generate a retimed ternary data stream.
