Abstract: The invention relates to a method and an apparatus for sound processing, where sound is attenuated by measuring it and by producing with an actuator a sound field of opposite sign in view of the original sound field. A desired value signal (I) is supplied to the actuator which reproduces the signal. To the actuator is attached a sensor, measuring sound pressure, and the difference of the sensor signal (B) and the desired value signal (I) is applied as high gain feedback to the actuator. As a consequence, sound not pertaining to the desired value signal (I) can be attenuated in a simple manner, and sound in accordance with the desired value signal (I) can be produced simultaneously with the same apparatus.

Abstract: A system is provided for automatically activating a boot-mountable highback between a walk mode and a ride position. In the walk mode, the highback is unrestrained, permitting the boot to flex freely, and consequently allowing the rider to walk comfortably. In the ride position, the highback is tilted toward the toe portion of a boot and prevented from movement in the heel direction beyond a preselected forward lean position, so that leg movement in the heel direction is transmitted through the highback into a gliding board. The highback is adjusted between the walk mode and the ride position simply by stepping into or out of a binding attached to a snowboard. Activation and deactivation of the highback may be achieved through direct or indirect interaction with a board-mounted actuator that may be attached to the binding. A forward lean adjuster may be provided that allows a rider to preselect the amount of forward lean attained when the highback is activated into the ride position.

Abstract: A method for directly imaging a lithographic printing surface using infrared radiation without the requirement of pre- or post-UV-light exposure, or heat treatment employs a printing plate which contains a support with a hydrophilic surface overcoated with an imaging layer. The imaging layer contains at least one polymer having bonded pendent groups which are hydroxy, carboxylic acid, tert-butyl-oxycarbonyl, sulfonamide, amide, nitrile, urea, or combinations thereof; as well as an infrared absorbing compound. The imaging layer may contain a second polymer which has bonded pendent groups which are 1,2-napthoquinone diazide, hydroxy, carboxylic acid, sulfonamide, hydroxymethyl amide, alkoxymethyl amide, nitrile, maleimide, urea, or combinations thereof. The imaging layer may also contain a visible absorption dye, a solubility inhibiting agent, or both. In practice, the imaging layer is imagewise exposed to infrared radiation to produce exposed image areas in the imaged layer which have transient solubility in aqueous alkaline developing solution, so that solubility is gradually lost over a period of time until the imaged areas become as insoluble as non-imaged areas. Within a short time period of the imaging exposure, the imaged layer is developed with an aqueous alkaline developing solution to form the lithographic printing surface. In this method, the infrared radiation preferably is laser radiation which is digitally controlled.

Abstract: An improved process for the purification of antibodies from human plasma or other sources is disclosed. The process involves suspension of the antibodies at pH 3.8 to 4.5 followed by addition of caprylic acid and a pH shift to pH 5.0 to 5.2. A precipitate of contaminating proteins, lipids and caprylate forms and is removed, while the majority of the antibodies remain in solution. Sodium caprylate is again added to a final concentration of not less than about 15 mM. This solution is incubated for 1 hour at 25 DEG C to effect viral inactivation. A precipitate (mainly caprylate) is removed and the clear solution is diluted with purified water to reduce ionic strength. Anion exchange chromatography using two different resins is utilized to obtain an exceptionally pure IgG with subclass distribution similar to the starting distribution. The method maximizes yield and produces a gamma globulin with greater than 99% purity.

Abstract: The present invention relates generally to novel genetic sequences which encode fatty acid epoxygenase enzymes. In particular, the present invention relates to genetic sequences which encode fatty acid DELTA12-epoxygenase enzymes comprising mixed function monooxygenase enzymes. More preferably, the present invention provides cDNA sequences which encode plant fatty acid epoxygenases, in particular the Crepis palaestina DELTA12-epoxygenase and homologues, analogues and derivatives thereof. The genetic sequences of the present invention provide the means by which fatty acid metabolism may be altered or manipulated in organisms such as yeasts, moulds, bacteria, insects, birds, mammals and plants, in particular to convert unsaturated fatty acids to epoxygenated fatty acids therein. The invention extends to genetically modified oil-accumulating organisms transformed with the subject genetic sequences and to the oils derived therefrom. The oils thus produced provide the means for the cost-effective raw materials for use in the efficient production of coatings, resins, glues, plastics, surfactants and lubricants, amongst others.

Abstract: A debridging tool incorporated into an automated wave soldering system adjacent to and after a wave soldering station removes bridges and/or excess solder formed during the wave soldering process by emitting, at a desired temperature which can be set using a heater and one or more thermo measuring devices, a pressurized stream of air, inert gas or other fluid only under selected areas of a printed circuit board, including a flexible circuit. The tool comprises a movable nozzle from which the stream is emitted and a means for transporting the nozzle under the printed circuit board. The tool targets only those areas of the board where bridges or excess solder repeatedly form during the soldering process without disturbing solder joints where no bridges or excess solder form. Since the debridging tool is positioned close to the wave soldering station, the latent heat from the soldering process remains in the printed circuit board, and the gas mass is relatively small, the pressurized stream may be kept below the temperature of molten solder. An inert environment around the selective debridging tool and the wave soldering station may be used to reduce the oxidation of the solder and reduce the formation of dross in the solder pot. The main soldering tower of the wave soldering station may have a removable insert with a non-round roller for generating a turbulent wave in the main soldering tower when the insert is installed.
