Abstract: There are disclosed a cuvette and a method of use which prevent nucleic acid amplified by PCR technology from being released to the atmosphere, while still proceeding to a detection step to determine whether or not the nucleic acid is present. Detection reagents are either pre-incorporated into the cuvette or added after amplification. In the latter case, a check valve prevents amplified nucleic acid from being released. Transfer of liquids between compartments is achieved via the use of flexible compartment walls and an external pressure source, or via pistons that are part of the cuvette and operate on the compartments as a piston within a piston chamber.

Abstract: ABSTRACT An apparatus for forming and slitting spirally formed pipe, particularly spiral pipes having a diameter of approximately one inch or less, is disclosed.  The pipe forming apparatus includes an enclosed forming head and a mandrel.  A continuous strip of metal is driven around the mandrel and inside a lateral bore in the forming head in a helical manner.  First and second rollers mounted in the forming head partially form a spiral lockseam.  A third roller mounted in the upper portion of the forming head closes the spiral lockseam. The mandrel is both rotatable and pivotable.  The device for slitting the spiral pipe into sections includes a first knife that is positioned inside the spiral pipe. This knife is mounted at the end of a rotatable boom, that extends through the mandrel and is positioned inside of the spiral pipe.  A second rotatable knife is positioned outside of the pipe.  A rotatable support roller is also positioned outside of the pipe, and opposite the outer knife.  To cut the pipe, the outer knife punctures the pipe and overlaps the inner knife, and the support roller abuts the opposite side of the pipe.  The inner and outer knives and the support roller move axially with the pipe.  As the pipe con-tinues to rotate, it is completely severed.

Abstract: An immunoassay for cellular proteins which may be present as contaminants in a product purified from mammalian cell culture.  Since mammalian cell culture requires the use of protein-containing media, the assay must be specific in recognizing cellular proteins but not media proteins. This is accomplished by selective adsorption of an antiserum to cellular proteins against media proteins. Quantification of the assay may be improved through the use of a purified antigen, namely fibronectin, which is known to be highly immunogenic.

Title: Switching system reliability
Inventor: CLINE WILLIAM K
IPC: H04Q11/04
Filed: 1989-09-29
Granted: 1993-06-22
Abstract: IMPROVEMENT IN SWITCHING SYSTEM RELIABILITY Abstract A switching system is disclosed in which inter-switch unit trunks interconnect the switch units of a distributed switching system and when the central switch, which normally advances connections between the switch units is unavailable, connections between switch units are advanced by control units of the switch units over the inter-switch unit trunks. The inter-switch unit trunks comprise a connection arrangement which is an alternative to the central switch. In one embodiment, the control unit of a first switch unit detects the unavailability of the central switch to advance connections and in response to a request for connection to destination line or trunk at a second switch unit transmits signaling information on a selected inter-switch unit trunk to the second switch unit. The second switch unit responds to the signaling information by completing a connection from the selected inter-switch unit trunk to the destination. In a second embodiment, an alternative path between an origination and destination switch unit is completed, via a first and second inter-switch unit trunk, which are serially connected by a selected path through an intermediate switch unit. The use of inter-switch unit trunks as an alternative to the central switch avoids possible subscriber isolation during a central office catastrophe, such as a major fire.

Abstract: In a dual bus microcomputer system using a cache memory and a cache controller, the timing requirements placed on non-cache memory components by the cache controller are more stringent than the timing requirements placed on the non-cache memory components by the microprocessor. A logic circuit operates on the cache write enable (CWE) signals, and delays those signals in the event of a cache read miss. Delaying the CWE signals relaxes the timing requirements placed on non-cache memory components and at the same time does not impact wait state parameters for read miss operations.

Abstract: A method for rapidly identifying microorganisms by determining the rates of enzymatic hydrolysis of a plurality of substrates in the presence of at least one enzyme activity affecting agent, called an "affector" is provided. The substrates are selected from fluorogenic and chromogenic substrates to create a characteristic pattern of enzymatic cleavage rates by enzymes expressed by the unidentified microorganism. This characteristic pattern of enzymatic cleavage rates is a "fingerprint" of the unidentified microorganism when in the presence of the affector. The pattern of enzymatic cleavage rates for the unidentified microorganism is compared to a pattern of enzymatic cleavage rates of the same substrates in the presence of the same affector for one or more identified classes or subclasses of microorganisms. The unidentified microorganism is then identified as belonging to a class or subclasses of the known microorganisms which most closely matches the pattern of enzymatic cleavage rates in the presence of the affector.

Abstract: A backside textured papermaking belt is disclosed which is comprised of a framework and a reinforcing structure. The framework has a first surface which defines the paper-contacting side of the belt, a second surface opposite the first surface, and conduits which extend between first and second surfaces of the belt. The first surface of the framework has a paper side network formed therein which defines the conduits. The second surface of the framework has a backside network with passageways that provide surface texture irregularities in the backside network. The papermaking belt is made by applying a coating of photosensitive resinous material to a reinforcing structure which has opaque portions, and then exposing the photosensitive resinous material to light of an activating wavelength through a mask which has transparent and opaque regions and also through the reinforcing structure. A process for making paper products is also disclosed which involves applying a fluid pressure differential from a vacuum source through the belt to a partially-formed embryonic web of papermaking fibers. The fibers in the embryonic web are deflected into the conduits of the papermaking belt by the vacuum pressure while the papermaking belt and the embryonic web travel over the vacuum source. Following the deflection, the paper web is impressed with the paper side network of the belt, and dried to form the final product.
