2091567 9206098 PCTABS00011 An acidic polycyclic ether antibiotic of formula (I), having structure established by X-ray crystallography, is formed by fermentation of a novel microorganism, Actinomadura sp. ATCC 55080. This novel antibiotic is useful as an anticoccidial in poultry, in the prevention and treatment of swine dysentery and as a growth promotant in cattle and swine.

2093356 9206103 PCTABS00011 A method for the synthesis of a plurality of oligonucleotides in which an oligonucleotide is formed by sequential reactions of precursors of individual nucleotides on a support, comprising the steps of (a) forming a first oligonucleotide; (b) attaching to said first oligonucleotide a cleavable linker moiety; (c) forming a second oligonucleotide on the cleavable linker m...

The present invention provides a membrane separation system with a recirculating closed loop design and a feed control valve outside the loop which admits feed to the loop under permeate level control. The system is operable with a constant recirculation flow thus minimizing membrane fouling. A fast flush is also possible without closing the permeate valve.

An ultrafiltration system with a reciculating closed loop design and a feed control valve outside the loop which admits feed to the loop under permeate level control was shown to be operable with a constant recirculation flow thus minimizing membrane fouling. A fast flush was also possible without dosing the permeate valve.

A roll for fabric or like material includes a core on which the material is adapted to be wound, and an end cap removably secured to each end of the core. The core has a replaceable, flexible flap which extends approximately 90 DEG around the core permitting the leading edge of the fabric or like material to be inserted under the flap so that subsequent turns of the wound material will not show a...

Method for obtaining acetic acid derivatives, such as glycin, IDA and NTA by dehydrogenation of mono-, di- and triethanolamine, respectively, in the presence of a Copper-Raney catalyst. Such method includes a step consisting in regenerating the catalyst spent in order to reuse it in successive reaction cycles. The regeneration method is comprised of the treatment of the spent catalyst with backflo...

12 9348 A runner guide for an elevator door includes a ramp member at an end of travel position along a guide rail for engaging a roller attached to the door and running on the guide rail. The roller has a rim disc which engages a surface on the ramp member to move an insert in the roller out of engagement with the rail thereby relieving the load on and preventing flattening of the running surface...

A unique method/system for simultaneously creating and transferring a contrasting pattern of intelligence on and from a composite ablation-transfer imaging medium to a receptor element in contiguo us registration therewith is improvedly radiation sensitive and versatile, is kinetically rapid and not dependent on a sensitized ablative topcoat, and is well adapted for such appli- cations as, e.g., c...

A synthetic resin clip having a rebound produced by molding a resin material mainly composed of a thermoplastic polyester as a primary material into a clip base and integrally composite-molding a resin material mainly composed of a flexible thermoplastic polyester elastomer as a secondary molding material on the surface or the fitting site of the surface of the clip base by double molding or two-c...

According to a process for regulating the amount of copying light in a closed control loop of a photographic color photocopier equipped with color filters, the copying light influenced by the color filters is selectively measured in the primary colors, red, green and blue. A deviation resulting from the comparison of the real values with predeterminable set values is subdivided into a color deviat...

Improved distention device for the treatment of contractures of the paravertebral muscles, comprising two first parallel horizontal strips of adhesive tape connected to each other by means of more than one second vertical strips of adhesive tape, and in which the self- adhesive face of said strips is protected by a removable sheet of siliconated paper, the vertical strips being intended to be atta...

Method and equipment for sawing stone materials, in which a set of blocks of these materials is placed in a frame fitted with blades and in which cutting is carried out with the aid of an abrasive fluid pumped around a fluid circuit; during the cutting operation some of the fluid is diverted off the main circuit to undergo a heat treatment which changes its temperature so as to reduce the release ...
