The invention relates to the method of preparation of N-glycosyl compounds of anthracyclin antibiotics of formula I I where R1 is the hydrogen atom or hydroxylic group, whereas R2 is the residue of a mono- or oligosaccharide of a series of aldeses and ketoses or the derivatives reacted with the amine group of the antibiotic. The invention depends upon the reaction of the antibiotic, wh...

PURPOSE:To restore the computer automatically to normal state, by detecting the runaway of microcomputer automatically from the distortion in the period of the computer and resetting the computer. CONSTITUTION:In the binary counter 31 of the microcomputer 20, the initial pulse P0 of the computer 20 is input to the reset terminal RES and the pulse P1 is output from the terminal Q1. The binary count...

A .beta.-cyanoethyl blocking group is selectively removed from the phosphate moiety of a nucleotide or polynucleotide by treatment with a primary amine having from 3 to 5 carbon atoms or diethylamine. resistance to a drug in the presence of successively higher amounts of an agent such as a drug against which the gene confers resistance so the only those eucaryotic cells into which multiple copies ...

Platinum complexes of the following formula useful as antitumor agents with less nephro-toxicity and higher water solubility than cisplatin: wherein X and Y respectively or taken together represent a mono- or di-valent residue of hydroxycarboxylic acids.

D-22,815C FORWARD ERROR CORRECTION USING CODING AND REDUNDANT TRANSMISSION By Ake Sewerinson A forward error correcting digital transmission system having two separate transmission channels carrying redundant information. m e signal on the first channel is encoded by combining each present bit with itself delayed m bits in time. The signal on the second channel may be encoded in the same manner on...

An apparatus is provided for winding a continuous, flat strip onto a winding reel to form successive, abutting convolutions along the reel in multiple, flat layers to form a tight coil of strip, which strip may typically be an alloy such as stainless steel. The apparatus includes a winding reel fixedly mounted and having means for imparting axial rotation to continuously wind said strip onto the r...

An all metallic club head including a hollow body and a sole plate attached in a cut-out in the hollow body. The hollow body includes a front wall providing a generally flat impact face of a club head, a top wall defining a generally round upper side of the club head, a rear wall defining a back of the club head and a bottom wall providing the cut-out through which the hollow body opens downwards ...

By-product effluent streams from pyrolytic hydrocarbon cracking processes, containing monoolefins and diolefins, are treated to hydrogenate the olefins and to aromatize the aliphatics, with a catalyst essentially comprising a calcined TEA-silicate.

CONSTITUTION:Slots 5, 6... are formed on the surface of a stator 2, and piezoelectric elements 18, 19, 20, 21... are respectiv...

This invention is concerned with pitch lock of the variable pitch fan blades of a propulsor whose pitch is varied by a rotary type actuator and where the pitch lock input signal is manifested by a negative torque reaction imparted by the blades.

The torque to the blades for pitch change movement of a variable pitch fan of the type having a harmonic pitch change actuator is increased by coupling both the outputs of the rigid spline and flexispline to drive the blade for pitch change movement.

PURPOSE:A laminate composed of a metal and an olefinic polymer with excellent salt water resistance and a process for manufacturing it.

The film comprises a blend of (I) at least one member selected from the group consisting of (A) elastomeric block copolymers of vinyl-aromatic compounds with conjugated diene compounds, (B) resinous block copolymers of vinyl-aromatic c...

A process for preparing novel catalysts of increased activity which comprises (1) mixing alumina with at least one metal compound selected from the group consisting of Group IVB metal compounds and compounds of vanadium, chromium, manganese, tungsten, nickel and cobalt and an aqueous solution containing at least one dissolved compound therein that imparts to said aqueous solution a pH below 6 and ...

A surface acoustic wave bandpass filter has a piezoelectric substrate for propagating a surface acoustic wave. An input transducer is formed on the substrate, with a pair of interdigital electrodes, for exciting a surface acoustic wave in response to an electrical signal. An output transducer is also formed on the substrate, with essentially the same structure for developing a filtered electrical ...

A method and apparatus are shown for monitoring respiration volumes by continuously measuring, while the patient breathes, variations in the patient's chest cross sectional area, or preferably, variations in both chest and abdomen areas. Each area is measured by measuring the inductance of an extensible electrical conductor closely looped around the body, by connecting the loop as the inductance i...
