Title: Fill restricting drop tube
Inventor: PETTESCH MARTIN C
IPC: F16K31/18
Filed: 1995-10-10
Abstract: A drop tube for underground fuel storage tanks and the like has a flow restriction section that includes a plate or disc mounted for rotation and controlled by a float located outside the section. Unlike overfill shut-off valves that slam against a sealing valve seat and require springs and cams for their operation, the subject restrictor simply and slowly rotates the plate between a non-restricting position and one in which the plate closes off the delivery liquid flow. Since the plate and interior wall of the tube are not sealed, liquid above the restrictor can bleed past the plate into the storage tank after the delivery valve on the truck is closed. Overfill is unlikely because it would take several hours to overfill with the plate in the restricting position.

Title: Method and Apparatus for Data Replication
Inventor: JAIN SANDEEP
IPC: G06F17/30
Filed: 1994-09-09
Abstract: The present invention provides the ability to replicate modifications to a data item made at a local site to multiple remote sites in a peer-to-peer environment. Information regarding these replicated modifications (e.g., insert, delete or update) and associated exceptional occurances are contained in a set of replication tables which include transaction table, transaction nodes tables, calls table, call nodes tables and an exceptions table as shown in fig. 3.  The present invention provides both value-oriented row-level and logic-oriented procedure-level replications. The row-level replication uses the new and old values of a data item at an originating site to modify the remote site and the procedure-level replication modifies the remote sites based on the logical operation used to modify data at an originating site. The present invention further provides a trigger, a procedure that is executed every time a modification is made to a data item, which queues the entries in the replication tables.

Abstract: The invention relates to a method of manufacturing tape tabs for use in an absorbent article and to tape tabs made by said method. The method comprises providing a number of curved cuts (56) in a unitary strip of material (52) to form side extensions followed by creasing and folding over of the side extensions. After folding over of the side extensions, the unitary strip of material is cut along transverse cut lines (83) to form individual tape tabs (88). Alternatively, composite tape tabs are formed comprising a release member, by combining the unitary strip of material with a release strip prior to cutting the individual tapes. In one embodiment, the material that is cut from the rounded corner of one tape tab forms the side extension (57) of the neighbouring tape tab, which side extension is doubled over to form a reinforced gripping part. In another embodiment, cut-out sections are formed that are contiguous with the rounded corners of each time two neighbouring tape tabs. The cut-out sections are doubled over. The advantage of the method according to the invention is that no scrap is formed, that a reinforced gripping part is formed which easily detaches from a release surface and that a baby-friendly rounded corner is provided. <IMAGE>

Title: Curbside circuitry for interactive communication services
Inventor: CHEN HOWARD ZEHUA
IPC: H04N21/462
Filed: 1996-08-26
Abstract: Only one or only a few channels are sent at a time from circuitry located in a curbside box (15), via link (22) such as either a coaxial or a fiber cable, into a customer's home TV set (14) or personal computer. However, many more than a few channels are delivered to the curbside box, via a line (46,47) such as a fiber or a coaxial cable, from a central office (36) or a central bank (37) of paid video-movies to be selected by the customers. Thus whereas the link from the central office or central bank is relatively broad-band (e.g., 500 MHz to 1,000 MHz), the cable from the curbside to the home (or any other kind of building) can be relatively narrow-band (e.g., 5 MHz to 50 MHz). The curbside box serves a multitude of homes -- a separate (narrow-band) cable running to each home from the (same) curbside switch. Each channel can be a free radio or free TV channel, a stored or an on-line newspaper pay channel, or a pay TV channel, or pay-per-view channel (i.e., the customer must give advance notice per view, and may begin viewing in the middle of a selected program, or may come in at the beginning of a selected program with a short delay, depending on the sender's arrangement) Requests from each TV set ineach home (e.g., initiated by means of a hand-held remote control infra-red sending device (11)) can be sent to the curbside box from the home along a link (23) such as a wire or along the same curbside-to-home cable itself. In addition, billing of customers can be accomplished by means of another link (50) connecting a junction in the wire or in the curbside-to-home cable to one or more remote billing centers (40).
