Title: Method of and apparatus for voice communication storage and forwarding with simultaneous access to multiple users
Inventor: SZETO CHARLES
IPC: H04M11/10
Filed: 1984-01-16
Granted: 1989-11-16
Abstract: This technique for voice or other similar communication signal storage (such as recording) and forwarding (such as playback) enables simultaneous access to multiple users through use of first-in-first-out memories (FIFO), microprocessor-controlled to fill intermediate memory RAMs at irregular intervals and to transfer the contents to main memory RAMs for ultimate disc recording, with playback therefrom microprocessor-controlled at irregular intervals to transfer back recorded data blocks through the main memory RAMs and appropriate intermediate memory RAMs and FIFO memories associated with the appropriate playback channel or user; the various data transfers being controlled to avoid delays in the played back messages that are long enough to be perceived by the channel user, and with succeeding segments of data being transferred to intermediate memory RAMs by the time the transfer of the previous segment is complete, thereby to insure continuity of communication.

Abstract: The scarcity of high grade tungsten ores obliges users to seek to recover it from scrap materials, but drill bits in particular pose special problems. Existing proposals to use acidic hydrogen peroxide to oxidize and solubilize tungsten are extremely inefficient in reagent consumption per unit tungsten recovered. According to the present invention hydrogen peroxide can be used considerably more efficiently with sub-stoichiometric reagent addition per stage, especially from 6 to 12 stages and by the use of a small amount of certain promoters which it is believed may form a water-soluble complex with tungsten which provides an alternative route for tungsten dissolution. Many of the promoters are aromatic hydroxyl or amino acids such as 2-hydroxybenzoic acid, 2-aminobenzoic acid, 4-hydroxybenzene-phenol and its related oxidation products such as 1,4-benzoquinone. Also, certain aliphatic acids such as tartaric and epoxy succinic acid show some promotional activity.
