Filed:

Jan 29, 2001

Appl. No.:

09/770718

Inventors:

Edward J. Powers - Aurora IL

Assignee:

Mary F. Powers - Aurora IL

International Classification:

F16L 1112

US Classification:

137322, 251329

Abstract:

A tapping adaptor assembly for direct connection to a gate valve. The assembly includes a tapping adaptor attached to a main pipe. An outlet conduit formed integrally with and extend outwardly from the tapping adaptor terminates in a distal end outlet. A adaptor for mounting on the tapping adaptor includes an integral flange, a shoulder and a spout. The adaptor may be attached to the tapping adaptor by welding or glueing depending upon the material of the tapping adaptor or may be formed integrally with the outlet conduit. The flange of the adaptor has an annular face positioned to engage the gasket of the gate valve. The annular face may be recessed and an annular rim may be formed radially outwardly of the annular face. The spout of the mounting adaptor extends into the socket of the gate valve to help support the tapping sleeve. In an embodiment, a tapping sleeve semi-cylindrical section is formed integrally with the outlet conduit.

International Classification:

F16L 5500

US Classification:

Abstract:

A tapping sleeve assembly for direct connection to a gate valve. The assembly includes a tapping sleeve attached to a main pipe. An outlet conduit formed integrally with and extend outwardly from the tapping sleeve terminates in a distal end outlet. A retaining ring is attached to the outer surface of the outlet conduit and is located between the tapping sleeve and the distal end outlet. Opposed, longitudinally facing annular surfaces are formed on the retaining ring with one of the annular surfaces facing the tapping sleeve and the other facing the distal end outlet. The annular surface facing the tapping sleeve is inclined. A gland telescopes over the outlet conduit. The gland has a collar with an annular surface engaged with an annular surface of the retaining ring. A gate valve has a socket facing the outlet conduit, a gasket is positioned in the socket and a mechanical joint flange surrounds the socket. Bolts and nuts attach the gland to the mechanical joint flange of the gate valve.

Appl. No.:

6/003323

Inventors:

Edward J. Powers - Harrison NY

Assignee:

Stauffer Chemical Company - Westport CT

International Classification:

C01B 2530

US Classification:

423309

Abstract:

A mixture of disodium and monosodium orthophosphate in a 2:1 mole ratio is prepared by sequentially reacting phosphoric acid with monohydrate process soda ash and caustic soda in a semi-solid reaction medium. Milled monohydrate process soda ash is contacted in less than stoichiometric proportions with phosphoric acid and the resultant orthophosphate containing reaction mixture is brought to a sodium to phosphorus mole ratio of about 1. 67:1 by subsequent reaction with caustic soda. The final reaction product of mixed disodium and monosodium orthophosphate is suitable feedstock for conversion to sodium tripolyphosphate.

Assignee:

Pipeline Accessory Marketing, Ltd. - Aurora IL

International Classification:

F16L 1112

US Classification:

285197

Abstract:

A tapping sleeve for attaching a branch line to a main fluid conduit. The tapping sleeve has upper and lower sleeve members, bolted together around the main fluid conduit. Shell gaskets seal between the sleeve members and the main fluid conduit and a branch gasket seals around a side opening in the upper sleeve member. Metal shell gasket retaining rings secure the shell gaskets in place and a metal branch gasket retaining ring secures the branch gasket. In the preferred embodiment, the retaining ring has a circular cross section.
