Abstract: A process of encapsulating volatile aroma compounds in which an inert gas is dissolved in an aromatized edible liquid. The aromatized, gasified liquid is co-extruded with a molten carbohydrate material having a glass transition temperature of between 20 ° C and 80 ° C to provide a continuous extrudate having an outer shell of the carbohydrate material surrounding an inner core of the aromatized, gasified liquid. The continuous extrudate is extruded into a pressure chamber having a pressure higher than the internal pressure of the inert gas in the aromatized liquid core, and is maintained under such pressure until the carbohydrate shell has cooled to below the glass transition temperature. When placed in hot liquid, the inert gas expands and ruptures the capsules, releasing the aroma compounds.

Abstract: L'invention se rapporte à un procédé pour obtenir des cellules eucaryotes transgéniques, particulièrement de plantes. Ce procédé consiste à: mettre en contact une culture de cellules non transformées avec un inhibiteur de la poly-(ADP-ribose)polymérase pendant un temps suffisant pour diminuer la réponse des cellules cultivées au stress et pour diminuer leur métabolisme. Ensuite, les cellules non transformées sont mises en contact avec un ADN étranger comportant au moins un gène à étudier dans des conditions dans lesquelles l'ADN étranger est absorbé par les cellules non transformées et le gène à étudier est intégré de façon stable dans le génome nucléaire des cellules non transformées afin de produire des cellules transgéniques. Eventuellement, les cellules transgéniques sont récupérées à partir de la culture. De préférence, l'inhibiteur est l'amide nicotinique, de préférence à une concentration de 200 mg/l à 500 mg/l environ et les cellules non transformées sont cultivées dans un milieu contenant l'inhibiteur pendant une durée d'environ 3 à 14 jours avant d'être mises en contact avec l'ADN étranger. L'invention se rapporte également à une plante comprenant dans le génome nucléaire de ses cellules un ADN étranger intégré uniquement dans les régions du génome nucléaire qui présentent une activité de transcription dans les cellules de la plante lorsque les cellules sont traitées par une quantité efficace d'un inhibiteur de la PARP pendant un temps suffisant pour diminuer le métabolisme cellulaire à un niveau où l'expression génétique est essentiellement limitée à des gènes exprimés, sans tenir compte de la condition différenciée ou physiologique de la cellule.

Title: Differential audio line receiver
Inventor: WHITLOCK WILLIAM E
IPC: H04B1/18
Filed: 1995-12-22
Granted: 2009-10-06
Abstract: A bootstrapped audio line receiver that receives a differential-mode input signal from first and second differential lines and outputs a single-ended signal on an output line. The line receiver includes a differential amplifier and an input amplifier having differential output terminals and differential input terminals. The input amplifier is connected between the differential lines and the differential amplifier. The input amplifier provides a dc current path to a ground terminal while maintaining a high input impedance to ac signals at audio frequencies. The input amplifier also includes an rf filter that removes rf noise without adversely affecting the line receiver's common-mode noise rejection at audio frequencies. In one embodiment, the input amplifier includes two operational amplifiers connected for unity gain and having two bias resistors connected in series between each input terminals o f the input amplifier and a ground terminal. A capacitor is connected from the output of each operational amplifier to a node between ea ch set of series connected bias resistors and prevents the low impedance of the bias resistors from significantly degrading the line receiver's common-mode rejection ratio. Thus, the line receiver tolerates a wide range of balanced and unbalanced source impedanceswith a minimal deterioration of the line receiver's common-mode rejection ratio.

Abstract: An impact type flow meter for a particulate material such as cereal comprises a supply device for dropping the particulate material, an inclined load detection plate for receiving the dropped particulate material, and a load detector for detecting a load of the particulate material exerted to the load detection plate.  A bottom surface of the supply device is inclined at substantially the same degree with the load detection plate, and has at its lower end with a supply opening for dropping the particulate material onto the load detection plate.  The bottom surface serves to guide the particulate material to the load detection plate at substantially the same inclination therewith.  Thus, the flow meter has a buffer device for softening a dropping impact of the particulate material integrally incorporated in the particulate material supply device, and accordingly, the height is low and the whole apparatus is compact.  The particulate material impinges upon the bottom surface of the supply device, diverges width-wise thereof and reaches the supply opening.  Accordingly, the direction and position of dropping of the particulate material onto the load detection plate are fixed.  Further, the flow-down speed of the particulate material is lessened, unevenness of the speed is averaged or uniformed, thereby the flow meter is high in measurement accuracy.

Abstract: A control system for agricultural implements such as planters, conventional or air drills is disclosed herein.      The implement includes a frame with one or more sections.      Each section supports a plurality of row units configured to apply a product at variable rates to rows in a field.      The products can include seeds, fertilizers, insecticides and herbicides. In one configuration, the control system monitors the rates at which the product is applied to the rows. This configuration of the control system includes sensors configured to sense the rates at which product is applied, and a control module configured to monitor the sensed rates and generate a multiplexed output signal representative thereof. The output signal is used, for example, by a cab-mounted display or recording device.      The control system, however, can be reconfigured to both monitor and control the application rates by installing a second control module on the frame. The second control module generates rate control signals in response to rate command input signals. The rate control signals are applied to the metering device to cause the metering device to meter product to the row units at the commanded rates. Commanded rates are set, for example, by a cab-mounted display control module.

Title: A method and apparatus for switching signals using an embedded group signal status
Inventor: DIETZ PHILIP SIDNEY
IPC: H04L12/56
Filed: 1999-03-25
Granted: 2003-07-22
Abstract: A simple, elementary switch fabric is provided for switching individual signals as a composite group based on goup signal status that is embedded and carried within each of the individual signals in the goup. In general, a group signal status is derived for a group based on the signal status of each of the individual signals within that group. This group signal status is then individually encoded and embedded in each of the individual signals in the goup. The embedded group signal status can be extracted and decoded at any point within the transmission path, as necessary, to facilitate appropriate switching decisions. Although each individual signal is switched independently by the elementary switch fabric, the individual signals are effectively switched as a composite goup because the switching decision for each individual signal in the group is based on the same group signal status. That is, individual signals in a particular goup will either be selected or rejected together as a single, composite group.
