Abstract: ABSTRACT OF THE DISCLOSURE         This invention relates to a device for automatically watering plants or flowers.  The device comprises a pot adapted to retain the plant or flower therein.  The pot has at least one orifice at the bottom thereof.  A tank is provided which holds water and the tank and the pot sits on a base.  An automatic level control means is provided which controls the flow of water to the base from the tank based on the consumption of water from the base by the plant or flower and the loss of the water to environmental conditions.  This device allows for accurate control of the supply of water to plants or flowers, especially over an extended period of time.

Abstract: Abstract A method for dynamic replication of data under distributed system control to control the utilization of resources in a multiprocessing, distributed data base system.  Previously, systems providing for data repli-cation at nodes of a multiprocessing, distributed data base system required that a central node maintain control,  or that replicated data be synchronized by immediately conforming all copies of an updated data item.  By this invention, requests for access to data of a specified currency are permitted and conformation of updated data is selectively deferred by use of a control procedure implemented at each node and utilizing a status and control  (SAC)  file at each node which describes that node's view of the status for shared data items at other nodes.

Abstract: MANUFACTURING PROCESS FOR CHANNEL SEAL            Abstract Molten thermoplastic, such as polyethylene, and a hot melt adhesive are coextruded through a channel shaped profile die.  While still molten, the channel shaped strip, having adhesive between the ribs thereof, is brought into contact with a moving web of a thermoplastic e.g. polyethylene film, which is backed up by a roll at a controlled temperature.  The temperature differential between the roll and the molten thermoplastic is maintained so that the thermoplastic adheres to the moving web upon contact and thereafter cools to set the thermoplastic in the channel shaped profile.  The web is under tension so that contraction of the film upon release compensates for the contraction of the channel shaped strip as it cools.

Abstract: ABSTRACT          A secondary data channel is described for use in a four-wire communication system in which there is continuous wire between each of two coupling transformers at a first station and each of two coupling transformers at a second station.  In accordance with the invention, the transformer windings at each station that are connected to the transmission line wires are equipped with center taps that are connected to a secondary channel data set.  By these means a secondary data signal can be transmitted from  one station to another by applying a signal to the center taps of the two coupling transformers at one station and receiving such signals from the center taps of the two coupling transformers at the other station.
