Abstract: The present invention relates to new asymmetric heterocyclic ester derivatives of 1,4-dihydropyridine-3,5-dicarboxylic acids of the formula:    <IMAGE>  (I)  wherein R1 is a C1-C4-alkyl group; X and Y, which are identical or different, each represent O or S, at least one of the symbols X and Y being different from S; n is an integer equal to 1 or 2; and R2 and R3, which are identical or different, each represent H, CH3, CF3, C6H5 or halogenophenyl, it being possible for R2 and R3, taken together, to form a 5-membered to 7-membered spirocycloaliphatic group with the C atom of the heterocyclic group to which they are bonded; and their optical iomers and diastereoisomers. These new derivatives are useful as pharmaceuticals, in particular as vasodilators.

Abstract: The invention is a selective diverting device for diverting an individual cookie (10) from one conveyor belt path (3) to another location. It is preferably used in combination with a sensing device (24), such as a weigher, optical sensor, color sensor, or the like, the sensor (24) selecting out "rejected" articles and actuating the diverting member (1). The diverting member (1) itself comes in three embodiments, all similar, and a fourth embodiment which is somewhat different. The first three embodiments include a pivotable conveyor-belt (4) device which is automatically actuated (as by a piston or the like) to pivot out of the main conveyor belt path (3,2) when a "reject" article (10') is located thereon. In the fourth embodiment, the "reject" conveyor belt is a retractable device, not pivotable, and is for articles having a greater length than the spacing between two rollers (91-92) (since relatively large gaps occur in this embodiment).

Abstract: 1. Apparatus for the centrifugal separation of a mixture including at least one gaseous phase, this apparatus comprising, in a fixed enclosure (21), a rotating element constituted by a treatment rotor (24) incorporating perforated (48) discs (49) offset angularly one from the other, upstream by a rotary distributor (49.1) and downstream by a ventilator (36), the mixture to be treated being directed by the rotary diffuser, which transforms the upstream pressure drop due to the ventilator into a helical speed greater than the speed of rotation of the rotor, through the perforations of the discs to form active helicoidal streams, which latter are separated by dead helicoidal sheets trapped in the rotor and rotating substantially at the same speed as this rotor, in which sheets the heavy phase to be separated passes between the discs as far as the fixed part of the enclosure where it is collected and evacuated, characterized in that the treatment rotor (24) is interposed between an upstream chamber (27) for suction of the mixture to be treated and a downstream chamber (46) collecting the separated gaseous phase, the rotor comprising a coaxial hollow tubular shafting (52) which places in communication through end openings (54, 55) this collecting chamber (46) with the chamber (34, 35) of the ventilator, which is separated in the enclosure (21) by a partition (26) from the suction chamber (27), whereas the collecting chamber (46) is separated in the enclosure (21) by a partitioning (45), on the one hand, from the peripheral zone (32) in which arrives the separated heavy phase and a helicoidal leakage flow is established in the same axial direction (F.5) as that (F.1) of the principal flow of the mixture through the rotor, on the other hand, from a conical extension (31) of the enclosure forming cyclone and receiving the leakage flow charged with heavy phase to trap and collect the latter.

Abstract: This invention relates to an improved method of manufacturing injection molding manifolds for multicavity molding. The method includes gun drilling a longitudinal duct through a steel manifold body, drilling a transverse inlet duct to connect to an inlet on one surface of the manifold, and drilling diagonal outlet ducts to connect to spaced outlets on the opposite surface of the manifold. The outlet ducts are smaller in diameter than the longitudinal duct to match the rest of the system. Before the outlet ducts are drilled, end portions of the longitudinal duct are drilled out to a larger diameter and steel plugs having a tapered well are securely welded into them with the mouth of the well in alignment with the longitudinal duct. The plugs are larger in diameter than the central portion of the longitudinal duct to avoid the formation of thin knife edge portions where the outlet ducts join the longitudinal duct which often break down during use. The smaller diameter outlet duct is then drilled diagonally to intersect the well in the plug at its smaller blind end. The joint is then smoothly finished to remove any irregularities and provide a smooth transition between the larger diameter longitudinal duct and the smaller diagonal outlet ducts at each end.

Abstract: The invention relates to a shapemetering process and relative apparatus, that is, a process for continuous detection and measurement of the profile and flatness of rolled metal strip or non-metallic strip coming off mill rolls, and for continuous correction in real time of the errors from which faults and unevenness in the strip tend to originate, by exploitation of a single source of fluid power to register differences in pressure localized in relative zones ranged transversely to the path of movement of the strip, across its width. Such differences in pressure are proportional to differences in tension with which the strip is invested, and can be detected, measured and displayed so as to represent the shape of the strip analogically; the self-same pressure can likewise be exploited as a continuous and direct-acting control medium for actuation of conventional media utilized in correcting the thermal condition of the mill rolls.

Abstract: An implantable biosensor and method for sensing products, such as hydrogen peroxide, generated from an enzymatic reaction between an analyte, like glucose, and an enzyme in the presence of oxygen. The implantable biosensor is equipped with an enclosed chamber for containing oxygen and can be adapted for extracting oxygen from animal tissue adjacent the container. The reservoir of oxygen contained in the enclosed chamber is supplied to the enzymatic reaction from the side of the membrane opposite the enzyme. The enclosed chamber is designed to be impermeable to substances, like liquid and cells, that possibly can interfere with the supply of the oxygen permeating through the membrane to the enzymatic reaction. Also, the implantable biosensor is designed to optically or electrically sense products generated from the enzymatic reaction which serve as a function of the analyte.

Abstract: A method for enzyme immunoassay for a ligand suspected to be present in a liquid sample includes signal amplification by use of at least two enzymes and a blocked modulator for one of the enzymes. Ligand present in the liquid binds to an antiligand and an enzyme-labeled tracer. The resulting bound fraction is separated and the enzyme in the tracer removes the blocking group from the blocked modulator. The modulator activates or inhibits a second enzyme which catalyzes the conversion of a substrate to a product. The presence or absence of the ligand in the liquid is indicated by a signal, such as a color change or a rate of color change, associated with the product. The invention includes a new class of enzyme inhibitors and blocked inhibitors and a kit of materials useful for performing the method of the invention.

Abstract: Fast methods of tone detection and tone generation disclosed are particularly suitable for implementation in a digital signal processor. Chebyshev polynomials are employed to generate periodic waveforms and to detect such waveforms. In an alternative aspect of the invention, trigonometric formulae are employed to generate periodic waveforms which are representable as the sum of sine and cosine functions. Unlike analog techniques, the digital techniques do not entail long delays in the generation or detection of tones because a fast iterative recalculation is employed at each step. Accumulated error is avoided by restarting the procedure once a predetermined value is exceeded. Independent choice of a quality factor and a confidence level is provided by the digital tone detection technique.
