Abstract: L'invention porte sur des billes de chitine ayant une granulométrie fine et uniforme et constituées de spores de microsporidies contenant la chitine comme constituant principal des parois cellulaires, ainsi que sur des billes de chitosane de granulométrie fine et uniforme et obtenues par N-désacétylation de la chitine précitée. Les spores de microsporidies prolifèrent chez les insectes ou dans les cellules mises en culture pour produire les billes de chitine précitées. Les billes de chitosane sont obtenues par N-désacétylation de la chitine. Lorsque les insectes sont domestiqués sous forme de larves de vers à soie, 5 x 10<2> à 5 x 10<8>/ml de spores de microsporidies sont inoculés par voie orale ou percutanée dans la larve du ver à soie domestiqué ayant mué dans la seconde phase larvaire et prolifèrent dans celle-ci. Puis les spores ayant proliféré sont retirés de la larve du vers à soie domestiqué dans la cinquième phase larvaire et sont épurés pour produire des billes de chitine de granulométrie petite et uniforme à partir desquelles il est possible d'obtenir des billes de chitosane telles que précitées. Ces billes sont utilisées comme supports pour immobiliser ou encapsuler différentes substances telles que des antibiotiques et des micro-organismes.

Abstract: A movable subframe for tractor-trailers, commonly referred to as a slider, includes a retractable pin mechanism having improved locking pins (149) for locking the movable subframe in a selected position relative to the tractor-trailer body. The improved pin includes a tapered or truncated conical-shaped portion (151) which nests in a tapered enclosure (164) when the pins are in the fully extended or locked position. When one or more of the pins of the retractable pin mechanism become jammed in the locked position due to slight misalignment between the respective slider and trailer body openings through which each pin extends when in the locked position, a generally uniformly distributed contact surface pressure exists between the truncated conical-shaped portion (151) of the pin and the tapered enclosure. Other parts of the pin are subjected to relatively intense contact point pressures. Such pressures in turn cause shear forces which resist retraction of the jammed pins. However, a vehicle operator attempting to free the pins needs only to slightly retract the pin mechanism and clearance is created between the tapered portion of each jammed pin and the tapered enclosure, much like pulling two tapered cups apart when one is stored within the other. Once clearance occurs, the areas of contact point pressure on the pin at other locations also are relieved. The retraction of the jammed pins of the present invention is achieved without overexertion on the part of the vehicle operator and/or damage to the retractable pin mechanism.

Abstract: A container level sensor is disclosed comprising an elongate strip member for mounting in a container in a generally upright orientation. The strip member has a measurable capacitance that changes as the level of material stored in the container changes. Two insulated conductive strips, held apart by magnetic forces or resilient spacers, can be used to form a capacitor, with the force of material in the container against the sensor pushing the strips together and thereby changing the capacitance. This change can be measured by a circuit.

Abstract: A restoration procedure for use in bidirectional multiplex section-switched ring transmission systems re-establishes a connection path by using a loopback connection at nodes bordering the failure and by then establishing a jumpered connection path, for each active tributary affected by the failure.      The jumpered connection path at affected node eliminates any unnecessary loop formed in the re-established connection path caused by the loopback connection at the border nodes. There is stored in memory at each node (1) the provisioned connection path, (2) the jumpered path, and (3) a jumper flag is set indicating that a jumper connection exists. When the failure is cleared the (1) jumpered path is removed and its record erase from memory, (2) the provisioned connection path is restored, and (3) the jumper flag is reset.      Advantageously, the this operation can be programmed into existing node controllers and is compatible with existing restoration procedures.

Abstract: The present invention relates to a fabric handling device. Conventionally, fabric workpieces are manually lifted, visually inspected for proper orientation, and then manually flipped as necessary. The present invention takes the workpieces from a stack in which the sides facing up alternate, and automatically places them in the same orientation prior to arrival at a sewing station. A computer controlled picker (10) is used to separate the top workpiece (11) from the remaining workpieces in the stack (12), and for depositing the workpiece on a downstream conveyor (14). An ultrasonic face detector (16) is mounted above the conveyor for determining whether the side of the workpiece facing the face detector is relatively rough or smooth. A  pivoting feeder/inverter (20) is provided at the end of the conveyor. If the workpiece is correctly oriented, the inverter/conveyor is placed in a first position so that the workpiece will not change orientation. If the workpiece is incorrectly orientated, the feeder/inverter is pivoted to a second position to enable the workpiece to enter an inverter conveyor, which will rotate the workpiece 180 degrees.

Abstract: Disclosed is a method of making an idler roller for conveyors having an outer shell and end bearing assemblies, as well as idler rollers made by the method. The method includes the steps of press fitting an inner race of each of the two bearing assemblies of the roller onto a roller shaft to an initial position which is spaced axially outwardly from a final desired position, mounting the end caps into the outer shell of the roller, restraining the outer shell, and axially reciprocating the shaft relative to the shell to determine the degree of axial movement which is equal to the bearing clearance. The inner race of the bearing assembly is then moved from its initial position to its final position determined by the degree of axial movement. The resulting idler bearing having tapered roller bearings has precise and consistent end-play settings, is relatively easy to produce, and is affordably priced. The method allows for the production of such idler rollers automatically and at high volume.
