of the Invention A method and apparatus for compacting strands of shirred casing by applying substantially equal and opposite forces simultaneously to both ends of the strand. In one embodiment this double-ended simultaneous compaction is achieved by compacting the strand about a sliding sleeve and against a restraint so that movement of a compaction arm against only one end of the strand will cau...

A process for producing improved yields of aromatics (benzene, toluene, xylene) by initially partially thermally cracking heavy hydrocarbon and thermally cracking ethane to high conversion and then completely cracking the partially cracked heavy hydrocarbon with the completely cracked ethane.

Plasmin inhibitory substances have been found in mammalian omental extracts. The substances all contain lipid components. In addition, related commercially available lipid containing molecules, such as mono-, di-, and trisialogangliosides are found to possess unexpected plasmin inhibitory properties. This suggests methods of therapy for diseases and conditions where blood clotting and fibrin degra...

There are disclosed macrolides isolated from the fermentation broth, with avermectin Bla, avermectin Blb or 22,23-dihydro avermectin Bla as a substrate, of a known microorganism identified as MA-6181. The structure of the novel compounds isolated from the microorganism are presented based upon analytical studies. The compounds are highly potent antiparasitic, insecticidal, and anthelmintic agents....

A method of performing an oxidation reaction in which an alkali hypohalite is used as an oxidizing agent which comprises: carrying out the oxidation reaction in an aqueous medium with concurrently distilling off a solvent used in the reaction as the reaction proceeds under a reduced pressure. The method is in particular useful for the oxidation of diacetone-L-sorbose to diacetone-2-keto-L-gulonic ...

Carbonating agents are prepared by reacting bicarbonate ions with the amino moiety of glucosamine or galatosamine in aqueous solution to form glucoasamine bicarbonate or galactosamine bicarbonate. The bicarbonate is then isolated by drying. The resulting dry 2-amino sugar bicarbonate is stable at room temperature and can be used as a carbonating agent. It may be used with other constituents to for...

The immunogens comprise the drug coupled at its 2'-position to an immunogenic carrier material. Similarly, the labeled c...

Heptaose compounds of the general formula: (I) in which R and R1, independently of one another, each represent a straight-chained or branched alkyl or alkanoyl radical containing up to 6 carbon atoms or a phenyl radical or R and R1 together also form a methylene bridge, the hydrogen atoms of which, independently of one another, can each be substituted by an alkyl radical containing up to 5 c...

PURPOSE:To avoid the occurrence of obstruction on a film for chemical analysis due to a ultrasonic energy, by using a ultrasonic horn where a projection of a surface of the ultrasonic vibration horn being capable of contacting tightly on an upper frame does not completely include the film for the analysis. CONSTITUTION:A film 3 for analysis is put in a cavity 4 of a lower frame 1 with an upper fra...

PURPOSE:To change successively an angle position of a mount roller and to prevent thereby the outer circumference of the mount roller from the damage due to heat, by connecting and driving directly a driving motor with the mount roller, and rotating and driving the driving motor and the mount roller by a specific angle with each melt-cutting and heat sealing of the plastic film. CONSTITUTION:After...

i. An automatic bundle-tying tool is disclosed which is distinguished from the prior art by having a compact housing with a pair of curved pincer-shaped jaws, one of which pivots outward to accommodate a bundle of wires or similar elongated objects, and then pivots inward to abut the other, fixed jaw.
