Filed:

May 22, 1986

Appl. No.:

6/868171

Inventors:

Terry S. Floyd - Clover SC
Wyatt P. Hargett - Matthews NC

Assignee:

CEM Corporation - Matthews NC

International Classification:

F16K 1514

US Classification:

137522

Abstract:

The present invention provides an improved valve. This valve opens and closes in response to a change in the physical environment of the valve. This valve is particularly suited as a relief valve in a microwave system-based, closed vessel digestion procedure. This valve includes a pressure-deformable, resilient wall member having a fluid vent port, and an obstructing member that cooperates with the wall member to open and close the valve. Also provided is a lidded vessel employing this improved valve, an apparatus that includes a microwave system and this lidded vessel, and methods using this improved valve.

International Classification:

A24D 304

US Classification:

131332

Abstract:

Ventilated thermoplastic polymer foam filter rods and the processes for their preparation. The ventilated thermoplastic polymer foam filter rods are characterized by the presence of at least some cells which are bridged by fibrils, the rod being surrounded by a high density skin structure having a discontinuity such as to produce a ventilation of at least 50%. Discontinuity in the skin structure may be produced by skin solvent etching, skin abraiding, skin perforating and skin cutting.

International Classification:

D02G 112

US Classification:

28263

Abstract:

An improved stuffer box crimping apparatus of the type in which tow is fed into a rectangular cross-section crimping chamber off-set from the bite of a pair of feed rolls, the apparatus employing a crimping chamber wherein one wall is predominantly formed by a single doctor blade and an opposite wall is formed by a portion of the rotating surface of one of the cylindrical feed rolls of the feed roll pair, the doctor blade being pivotally mounted on the feed roll nearest the tip portion of the doctor blade. The cross-sectional area of the crimping chamber diminishes toward the exit portion thereof, whereby crimped filamentary material within the crimping chamber is subjected to both back pressure and a constant forwarding action by the rotating surface of the cylindrical feed roll. The pivotal mounting of the doctor blade provides precise clearance and allows the volume of the crimping chamber to adjust in accordance with tow variations.

Appl. No.:

7/813363

Inventors:

Terry S. Floyd - Lake Wylie SC

International Classification:

B01L 300

US Classification:

422113

Abstract:

A high temperature, high pressure chemical digestion vessel comprising an inner container which fits within an outer casement. Tapered walls of the inner container define an air gap which insulates against excessive heat transfer between the inner container and the outer casement during high temperature and pressure digestion. The container is provided with a vent. A replaceable, rupturable pressure release disk is provided having a predetermined rupture pressure for being sealingly interposed in covering relation to the vent to seal the container and thereby enclose a substance to be digested in the container. The disk ruptures and releases pressure within the container if pressure within the container reaches the predetermined rupture pressure. The pressure release disk comprises a flat sheet material. A seal cap is provided for holding the pressure release disk in sealing relation to the vent in the container.

Assignee:

Celanese Corporation - New York NY

International Classification:

B65H 2504

US Classification:

226 1

Abstract:

The present invention relates to: process and apparatus for feeding continuous filaments to a continuous multifilament structure utilizing tangentially converging fluid streams to forward the filaments; process and apparatus for detecting breakage of filaments utilizing a rotatable cylinder, or a gap in a three dimensional body, wherein breakage of the filament causes a measurable change in the pressure of fluid flowing to the cylinder or the gap; process and apparatus for the production of continuous multifilament structures wherein, upon breakage of a continuous filament, the breakage detector automatically activates a filament feeder to temporarily insert a substitute filament.

G01N 3112
F16J 1312

US Classification:

422113

Abstract:

A high temperature, high pressure chemical digestion vessel comprising an inner container within which digestion is to take place under high temperature and high pressure conditions. The container is provided with a vent. A replaceable, rupturable pressure release disk is provided having a predetermined rupture pressure for being sealingly interposed in covering relation to the vent to seal the container and thereby enclose a substance to be digested in the container and to rupture and release pressure within the container if pressure within the container reaches the predetermined rupture pressure. The pressure release disk comprises a flat sheet material. A container cap is provided for holding the pressure release disk in sealing relation to the vent in the container. An outer pressure resisting-casement is provided for receiving the container therein and providing support to the container.
