Granted: 1995-02-14
Abstract: A process for producing pyridine-2,3-dicarboxylic acid derivatives of the formula                  (I) is described. The process is based on the cleavage of HNR10R11 from 1-amino-1,2,3,4-tetrahydropyridine-2,3-dicarboxylic acid derivatives of the formula II                                  (II) to give 1,4-dihydropyridine-2,3-dicarboxylic acid derivatives of the formula III                                    (III); and subsequent oxidation of these compounds to obtain pyridine-2,3-dicarboxylic acid derivatives of the formula I. According to one variant of the process, the 1,4-dihydropyridine-2,3-dicarboxylic acid derivatives of the formula III are obtained directly, without isolation of the intermediately formed l-amino-l,2,3,4-tetrahydro-pyridine-2,3-dicarboxylic acid derivatives of the formula II, by reaction of .alpha.,.beta.-unsaturated hydrazones of the formula IV                                     (IV) with ethene-1,2-dicarboxylic acid derivatives of the formula V                                     (V); and subsequently oxidised to pyridine-2,3-dicarboxylic acid derivatives of the formula I. In the above formulae, R1, R2, R3, R4, R5, R10 and R11 have the meanings defined in claim 1.    The pyridine-2,3-dicarboxylic acid derivatives of the formula I are intermediates for producing herbicidal active substances.

Abstract: ABSTRACT          Severed Label Applicator with Anti-Gumming Lubricant Applying Means The invention provides a method for applying labels to articles moved one by one past an application station. The labels are cut from a web which is fed through the machine, the web having adhesive applied to one side thereof which is pressure sensitive immediately before application to the articles.  The machine includes cutting rollers which cuts through the adhesive side of the web in order to sever the labels therefrom, and the cutting edges of the cutting roller are kept clean by applying thereto liquid silicone or the like release composition. The liquid silicone is preferably applied by means of sleeves impregnated with the liquid silicone, such sleeves being rotatable on a spindle which is parallel to the axis of rotation of the cutting roller The machine also has gearing coupling a device for feeding the web of materials to the cutting location. The cut labels are held by a vacuum drum before being applied to the articles and the gearing is also coupled to said vacuum drum.            The machine is designed to operate continuously so that high speed application of the labels to the articles can be achieved.

Abstract: ABSTRACT OF THE DISCLOSURE An acousto-optic tunable filter is modified in order to provide a minimum of resolution degradation when operated in a wavelength scan mode.  A second face of the acousto-optic crystal opposite the first face on which the acoustic transducer is mounted is disposed so  as to be non-parallel  to the first face.  As  a result,  acoustic waves launched into the acousto-optic crystal are reflected by the non-parallel second face resulting in the production of minimal diffraction of the light passing through the crystal by reflected acoustic waves.

Filed: 1988-05-20
Granted: 1993-03-23
Abstract: ABSTRACT OF THE DISCLOSURE          An extrusion die for extruding a honeycomb-shaped structure having rectangular channels. The die is formed of a hard, rigid material, preferably metal, and includes a body plate and an abutting face plate.  The outlet face of the body plate is brazed to the inlet face of the face plate.  The body plate has a plurality of slightly staggered primary feed holes,  the outlet ends of each communicating with an associated feed reservoir,  the latter each defined by a recess or depression in the inlet surface of the face plate.  Each feed reservoir communicates with the inlet ends of three associated secondary feed holes.  The outlet surface of the face plate integrally carries a plurality of  intersecting slot  segments defining rectangular pins.    The outlet end of each secondary feed hole communicates with and feeds an associated intersection of groove segments.  The arrangement is such that the number of slot intersections is greater than the number of secondary feed holes, with two diagonally opposite corners  of  any  pin communicating with a secondary feed hole.  The combination of rectangular pins  (discharge slots) and staggering of the main feed holes maximizes the die interface brazing area to thereby realize honeycomb cell densities of 900 - 1400 cells per square inch.

Abstract: This invention relates to a novel method for the delivery of cytotoxic drugs to tumor cells by the administration of a tumor-specific antibody-enzyme conjugate that binds to the tumor cells, and the additional administration of a prodrug that is converted at the tumor site, in the presence of the antibody-bound enzyme, to an active cytotoxic drug.  According to preferred embodiments of this invention, antibody-enzyme conjugates containing the enzyme, alkaline phosphatase ("AP"), have been used in conjunction with the novel prodrug, etoposide-4'-phosphate or 7-(2'-aminoethyl phosphate)mitomycin or a combination thereof, to effect killing of tumor cells.  According to another embodiment of the invention, an antibody-enzyme conjugate containing the enzyme, penicillin V amidase ("PVA"), has been used in conjunction with a novel prodrug, N-(p-hydroxyphenoxyacetyl) doxorubicin to effect killing of tumor cells.  Still another embodiment of the invention relates to the use of an antibody-enzyme conjugate containing the enzyme, cytosine deaminase ("CD"), in combination with the prodrug, 5-fluorocytosine, to effect killing of tumor cells.  The methods, antibody-enzyme conjugates, prodrugs, pharmaceutical compositions and combinations of this invention provide for enhanced selective killing of tumor cells and are thus useful in the treatment of cancers and other tumors.
