A spinneret fabrication process that includes the steps of forming a countersink in the bottom of previously formed counterbores of a spinneret plate then punching through the countersinks to form capillaries is improved by supporting the immediate area of each counterbore with a flat-head pin anvil during the forming and punching steps.

Lithium parachlorophenoxyacetate is a novel medicament active in the treatment of mental diseases. It is prepared by reacting parachlorophenoxyacetic acid with lithium carbonate.

This invention is a method for making punches for punching complicated hollow filament spinning capillaries in one step. An inverse first punch is machined and then used to punch complicated inner recesses in the end of punch stock for the ultimate second punch. The second punch is further finished by machining. In addition, the complete method requires punching a complete female die using the second punch and then punching capillaries in spinneret webs located between the aligned die and second...

This specification concerns the use to treat hypertension in mammals of certain known 6-phenyl-4H-s-triazolo[4,3-a][1,4]benzodiazepines.

Process for preparing 3-[(4S)-5-oxo-2-(trifluoromethyl)-1,4,5,6,7,8-hexahydroquinolin-4-yl]benz- onitrile, pharmaceutical compositions containing the compound and methods of treatment using the same.

There are provided an encipher method of enciphering message data made by a microcomputer or the like at a high speed by using encipher keys which have previously been stored in a smart card or the like and a decipher method of deciphering the ciphertext made by the encipher method at a high speed by using the encipher keys. The encipher method and the decipher method are suitable for, particularly, a 32-bit microcomputer and include a process expressed by the function Rot.sub.2 i(x) (i=2, 3, 4)...

An improved grouting method and arrangement using aqueous solutions of alkali silicate materials confined between a pair of pile seal assemblies in sealing the annular space formed between either a jacket leg or pile sleeve and a pile driven therethrough or similar annular space of an offshore platform to support a column of grout thereon so that the annular space may ultimately be filled with grouting material.

A separator screw and housing with conical intermediate portion and with inlet intermediate its two outlets, has a much greater screw pitch on its forward cylindrical end than in the adjacent end of the conical portion. Beyond the forward outlet is a single cylindrical feed-out screw and housing, with the feed-out screw run at a much slower speed than the separator screw. Pressure sensors in the conical portion of the separator screw give a differential pressure on the basis of which the speed o...

An improved method of fracturing an underground fluid bearing formation penetrated by a well bore for the production of fluids therefrom by injecting a composition comprising cement, sand and oil, capable of forming a fluid permeable barrier in said formation at a pressure sufficient to form fissures therein extending from said well bore, and thereafter maintaining pressure on the composition for a predetermined period to permit the composition to set and form a fluid permeable barrier in the fo...

An apparatus for and method of drying articles such as tubular containers each having a bottom wall, an adjoining side wall, and an open end wherein said containers are supported in an inverted position and a drying gas moved therepast in such a manner that it circulates around and within the containers and provides efficient drying of both the interiors and exteriors thereof.
