Abstract: Catalytic converters for automotive exhaust systems wherein thin, resilient, flexible, intumescent sheet materials are utilized as mounting mats for catalytic monoliths are disclosed. Multiple wraps of such sheet materials have been found particularly useful and cost effective for positioning and supporting ceramic catalytic monoliths which have a large cross-sectional dimensional tolerance within the metallic casing of the converter.

Abstract: A superior method and magnetron sputtering cathode apparatus in which some of the flux lines forming the closed-loop magnetic tunnel are made to change their curvature from convex to slightly concave within a region of the tunnel intersecting the sputtering target volume, and over a substantial fraction of the tunnel width. The improved field shape reduces the tendency of the eroded area of the target to become narrower as erosion progresses, and thereby allows more complete consumption of the target.

Abstract: A split labyrinth seal comprises a stator and a rotor, each comprising a pair of halves. The rotor halves each comprise a hook and a further protrusion extending from the edge on one side of a central aperture and on the other side of the central aperture a recess in the edge for receiving the hook and the further protrusion. The hook and further protrusion and the recess to receive the same, each extend from adjacent the central aperture to the periphery of the half. The rotor halves are identical so that the hooks and protrusions of one half matingly engage the recess of the other half. The stator has a planar mounting wall and a peripheral wall extending axially to house the rotor therewithin. The edge of the stator on one side of the central aperture is recessed on the exterior side of the planar wall and on the other side of the central aperture is recessed on the interior side. The stator halves are identical at their edges, whereby the recessed edges overlap.

Abstract: A method of treating an aqueous or non-aqueous system, including paints and adhesives, is described which comprises adding to the system a thiolan of the formula: ##STR1## wherein each of X and Y, which may be the same or different, represents fluorine, chlorine or bromine, in combination with an alkylene bisthiocyanate and a 2-N-alkyl-4-isothiazolin-3-one.

Abstract: Optical architectures are presented for performing fully parallel, carry-free computation with a trinary, modified signed-digit number representation to allow addition, subtraction and multiplication. Two different optical schemes involving position and polarization encoding enable the fabrication of modular trinary logic systems that accommodate trinary numbers of different magnitudes. The optical systems made up of redundant three-dimensional modules provide a designer with latitude to simultaneously carry out addition, subtraction or multiplication optically and with reduced complexity.

Abstract: The present invention is directed to a packaged semiconductor chip which effectively dissipates heat and has improved performance. The packaged chip has a plurality of lead frame conductors extending through the encapsulating material which are adhesively joined to the semiconductor chip, preferably by means of an alpha barrier. The conductors cover a substantial portion of the surface of the chip and thereby serve as conduits for the dissipation of heat from the chip. Wires are bonded to the conductors and extend from the conductors to the terminals on the semiconductor chip. In a preferred embodiment the semiconductor chip terminals are located along a center line of the chip. This allows for short connecting wires which in turn contribute to faster chip response.

Abstract: A tool component is provided which comprises an abrasive compact bonded to a cemented carbide support body. The abrasive compact has two zones which are joined by an interlocking, common boundary. The one zone provides the cutting edge or point for the tool component while the other zone is bonded to the cemented carbide support body. In use, the tool component is so located in the working surface of the tool that the lower zone is partially embedded in that surface. The interlocking, common boundary is located above the working surface.

Abstract: There are provided pharmaceutical dosage forms for oral administration comprising a gelatin capsule encapsulating an admixture of at least one solid hygroscopic medicinal substance, which would otherwise disturb the gastric tract balance, with an at least partially hydrogenated and/or solidified vegetable oil.

Abstract: An internal combustion engine having a pair of opposed pistons in a block has a piston connected to a respective crankshaft. A gear train synchronizes the speed and relative angular relationship between the crankshafts. A timing actuator, connected to and engaged with either of the crankshafts, permits continuous selective adjustment of the headspace between the pistons by varying parameters such as intake and exhaust port timing and air flow through the cylinder.

Abstract: A method of controlling the operation of a loader to encourage the use of an operator restraint mechanism is disclosed wherein a first signal is generated by a seat sensor to indicate the presence of the operator in the operator seat and a second signal is generated by a sensor in the operator restraint mechanism to indicate use of the mechanism. The hydraulic system will not be enabled unless the second signal is generated immediately subsequent to the generation of the first signal. Unless the first and second signals are generated in the proper sequence, the starting of the engine will also be disabled. The generation of first and second inverse signals, indicating the lack of the presence of the operator in the seat and the disengagement of the operator restraint mechanism, respectively, will disable the loader hydraulic system.

Abstract: A method and apparatus for cancelling cyclically recurring noise induced in a magnetic metal detector by movement of ferrous machine parts in the field of the detector provides for periodically sampling the output of the metal detector, delaying each sample for the duration of one cycle of the cyclically recurring noise, and subtracting the samples taken in one cycle from the output of the metal detector during the following cycle. The delay is accomplished by a delay line or shift register, or by storing the samples under microprocessor control. If the noise has a first component occuring at a first rate and a second component occuring at a second rate cancellation of both components may be accomplished.

Abstract: A potentiometer is driven by one of the serpentine arm assemblies used to maintain apron tension during formation of a round bale so that the output of the potentiometer continuously provides an indication of the size of a bale being formed in the baler. A microprocessor based control circuit senses the output of the potentiometer, converts it to a digital value, and compares the digital value with a value representing a desired bale size. When the two values are equal, the microprocessor computes the number of revolutions of a net feed roll that is required to wrap the bale a preselected number of times, energizes the net feed roll mechanism to feed net into the bale forming chamber, and counts the revolutions of the net feed roll. When the required amount of net has been dispensed, the microprocessor stops the net feed roll and activates a mechanism to cut the net. The size of a "full bale" is selected by actuating keys on a control panel.

Abstract: A method is provided for detecting up to four classes of oligonucleotides which have been separated by gel electrophoresis. The method entails labeling members of each class of oligonucleotide with dyes selected from separate sets of dyes so that members of the same class are labeled with dyes from the same set. The four sets of dyes of the invention consist of derivatives of fluorescein, 2',7'-dimethoxy-4', 5'-dichlorofluorescein, tetramethylrhodamine, and rhodamine X carboxylic or sulfonic acid, respectively. Dyes from these sets are spectrally resolvable under conditions of gel electrophoresis.
