Abstract: Disclosed is a case including a first compartment capable of accommodating a first device, possibly associated with a first display, the first compartment being delimited by at least a first wall delimiting a first opening and a first bottom integral with or capable of being fixed to the first wall. The case includes a second compartment which is removable with respect to the first compartment and which is delimited by at least one second wall and a second bottom which is integral with or capable of being fixed to the second wall and which extends along or parallel to a plane forming an obtuse angle with an extension plane of the first wall and/or the first bottom.

Abstract: A latch for a bracelet having an extensible buckle, includes a cap defining a recess and including a slide in which a slider is engaged, the slider being intended for connecting the cap (10) to a bracelet strand using first hinge elements (18). The slider includes at least first (16) and second (17) segments connected together by second hinge elements (20). The segments (16, 17) are folded into the recess when the latch buckle is not extended. The latch (1) further includes slider indexing elements provided in the cap so that the slider can assume a sequence of fixed positions relative to the cap, between a first and second end position. In the first end position, the slider is located in the recess such that the ends (14a, 14b) of the latch are at a minimal distance. In the second end position, the slider is located essentially outside the recess.

Abstract: The construction of transgenic animal models of human Alzheimer'disease, and methods of using the models to screen potential Alzheimer's disease therapeutics, are described. The models are characterized by pathologies similar to pathologies observed in Alzheimer's disease, based on expression of all three forms of the &bgr;-amyloid precursor protein (APP), APP695, APP751, and APP770, as well as various point mutations based on naturally occurring mutations, such as the London and Indiana familial Alzheimer's disease (FAD) mutations at amino acid 717, predicted mutations in the APP gene, and truncated forms of APP that contain the A&bgr; region. Animal cells can be isolated from the transgenic animals or prepared using the same constructs with standard techniques such as lipofection or electroporation.

Abstract: A method of feeding a work station, which utilizes a robot to grasp workpieces one after the other at a charging station to which the workpieces are successively conducted to feed them to the work station and to transfer the workpiece worked upon to a discharging station. The robot grasps every workpiece arriving at the charging station by a workpiece holder that grasps the workpieces at a predetermined place thereon and holds them during all the time of transfer thereof and working thereon and releases the workpieces only when they arrive at the discharging station. At the work station, the workpiece holder is held in a very precise position by a gripping block rigidly fixed to a member in the work station. An apparatus for practicing this method comprises a workpiece holder adapted to the geometry of the workpieces to be processed, and a gripping block mounted on a member in the work station and arranged to receive the workpiece holder and to securely hold the same in a precise position at the work station.
