Patent CA-2176179-A1 (CA)
Title: Reclamation process for tungsten carbide and tungsten-based materials
Inventor: SEEGOPAUL PURNESH
IPC: C01B32/949
Filed: 1996-05-09
Abstract: Tungsten carbide and/or tungsten can be recycled by oxidizing the tungsten composition at a temperature greater than 700°C to form a water insoluble tungsten trioxide. This is then reduced to form tungsten dioxide. The tungsten dioxide is subjected to a low temperature oxidation which forms monoclinic tungsten trioxide. The monoclinic tungsten trioxide is then dissolved in ammonia to form ammonium tungstate. If present, the binder metal such as cobalt is converted into the soluble ammine complex. This can be spray dried and carburized to form tungsten carbide. If the form composition includes cobalt or other binder metal, the ratio of cobalt to tungsten can be adjusted by adding cobalt salts or ammonium metatungstate to the aqueous solution prior to spray drying to form a precursor composition. This is uniquely suitable for forming a cobalt tungsten carbide composition.

IPC: H04N1/00
Filed: 1995-04-18
Abstract: A data multiplexing network is described which multiplexes a plurality of asynchronous data channels with an asynchronous data stream representing compressed voice signals and/or facsimile signals onto a single synchronous data packet stream. The single synchronous data packet stream is then transmitted by a high speed statistical multiplexer over a composite link to a second site using a modified high-level synchronous data link control protocol with an overlay of an advanced priority statistical multiplexing algorithm. The asynchronous data channels and the compressed voice channel and/or facsimile signals are demultiplexed and reconstructed for sending to other asynchronous computer terminals and to a standard telephone or facsimile analog port at the second site, respectively. PBX trunk interfaces are also provided to allow PBX's to share the composite link between sites. Communication between the first site by voice or facsimile and the second site is transparent to the users. The multiplexer efficiently allocates the bandwidth of the composite link by detecting silence periods in the voice signals and suppressing the sending of the voice information to preserve bandwidth. An advanced priority statistical multiplexer is also described which dynamically allocates composite link bandwidth to both time-sensitive and non-time sensitive data to maximize data throughout efficiency and quality while simultaneously reducing multiplexer processing overhead. <IMAGE>
