Abstract: "IMPROVED SWING CHECK VALVE"                   ABSTRACT OF THE DISCLOSURE         A gravity closed, swing check valve is provided in which the downstream surface of the solid clapper is semi-spherical and convex.  The body of the valve forms a concave semi-spherical cavity.  The radii of the clapper and cavity surfaces is the same.          The clapper is positioned so that its downstream surface bears evenly across the surface of the body cavity, when the clapper is in the fully open position.  Thus the cavity surface of the body acts as a stop for the clapper and the area of stop surface is relatively large.  Impact damage is reduced as a result.

Abstract: ABSTRACT     In a trophy having a figurine mounted on a support base, an adapter or ferrule permits ready assembly and inter-change of the figurine. The adapter is mounted in a bore of the support base. The adapter has a tubular wall defining a central passage which axially receives a threaded rod of the figurine. One or more resilient, deformable gripping fingers is formed integrally with the tubular wall and extends into the central passage. Each gripping finger has an associated slot extending through the tubular wall.          A first portion of each gripping finger is outwardly displaceable by the threaded rod through its associated slot, while a second portion of each gripping finger projects inwardly of the passage to grippingly engage the threaded rod. The gripping fingers are severable from the adapter by a twisting force applied to the threaded rod received in the central passage for ready release of the threaded rod from the adapter. The adapter can be replaced for mounting a different figurine on the support base.

Abstract: Chlorine may be recovered from residues from the fluidised bed chlorination of iron-containing metalliferous oxidic materials, such as ilmenite, bauxite, chromite, wolframite, scheelite, tantalite or columbite, the residues containing condensed iron chloride and blow-over bed solids, by heating the residue to revolatalise the iron chloride and reacting it with oxygen. The quantity of iron chloride in the oxidic material is controlled relative to the quantity of blow-over carbon so that the quantity of carbon is sufficient on combustion to provide the required heat but is insufficient to cause undue dilution of the chlorine produced by virtue of its combustion products. Chlorine of a concentration suitable for direct recycle to a chlorination process, e.g. of 30% to 50% volume concentration is produced.

Granted: 1994-03-29
Abstract: BANDWIDTH ALLOCATION AND CONGESTION CONTROL SCHEME   FOR AN INTEGRATED VOICE AND DATA NETWORK Abstract An integrated voice and data network includes a multiplexer arranged with a voice queue for storing voice packets and a data queue for storing data packets. Voice packets are transmitted for a predetermined interval T1. Data packets are transmitted for a predetermined interval T2. The predetermined intervals T1 and T2 may be of different durations. A separate signaling queue can be provided for storing received signaling messages. If a signaling message is moved into the separate signaling queue during either interval T1 and T2, that interval is suspended and the transmission of voice or data packets is interrupted until the entire signaling message is transmitted. Then the interrupted voice or data transmission is resumed for the remainder of the suspended interval T1 or T2. As an alternative, signaling messages can be transmitted during predetermined intervals between the intervals T1 and T2. Block dropping of low order voice bits also is described for reducing congestion at the node. The multiplexer guarantees a certain minimum bandwidth for voice traffic and data traffic. Concurrently, the multiplexer allows each type of traffic to utilize any spare bandwidth momentarily available because it is not being utilized by the other type of traffic. Signaling messages are serviced with very low delay and zero packet loss.
