Abstract: The invention relates to a yaw control device for an aircraft fitted with a supersonic nozzle having a rectangular or flat section comprising a supersonic throat extended by a diverging portion in which supersonic flow occurs. In order to enable the aircraft to be controlled in yaw in the absence of a vertical fin, the device of the invention makes use of jet control surfaces in the form of airfoils disposed in the diverging portion of the nozzle. The control surfaces are movable about respective pivot axes in order to generate a lateral force when in a deflected position, so as to enable the aircraft to turn about its yaw axis.

Abstract: A biological specimen cassette comprising a base and a lid wherein the lid is pivotally mounted relative to the base. The lid so pivots into the base that, once in a closed position, the lid is included within the base thereby providing to the cassette, an overall thickness which is equal to that of the base. Similarly, the lid has a tab which does not extend beyond the dimensions of the base.

Abstract: A modular test tube rack for assembly with similarly constructed racks comprise a flat rectangular body displaying, in a first position, a series of wells extending from its top wall to its bottom wall and adapt to receive tubes therein. A pair of handles vertically extend at opposite end walls of the body, each handle having a lower portion adapted to tightly engage an extension on each end wall and a hand gripping upper portion. The lower portion has a bottom edge configured to anchor with the top edge of the handle of an underposed similarly constructed rack to thereby enable a stacking of two more of these racks. In one embodiment, the body displays a second series of wells extending from the bottom wall to the top wall whereby the body, when in a second position reversed relative to the first position, may also receive test tubes, the handles being reversably mountable to the end wall extension to still enable a stacking of racks in the second position.

Abstract: An integral assembly of a multiplicity of spaced reagent tubes arranged in an aligned series wherein the tubes are integrally linked to one another by connecting portions and to a corresponding multiplicity of independently spaced seal caps by a multiplicity of bands, each band having one end integral with a seal cap and an opposite end integrally connected to two adjacent tubes. The bands extend perpendicularly to the series of aligned tubes and include an oblique hinge portion which is deformable so as to allow the cap to be independently manipulatable to pivot angularly and to superimpose the open end of a tube for sealing.

Abstract: An assembly of stacked modular containers for handling, transporting and storing microscope specimen slides is described. The side walls of the rectangular-shaped containers have slide interconnections so that the containers may be longitudinally slid relative to one another. A releasable locking arrangement is provided on the extension of one of the other container walls to prevent unwarranted longitudinal sliding movement of the containers and to retain them in a secured stack formation. The extension of the container wall is made flexible to enable manual disengagement of locking members on the extension to thereby allow the sliding of containers for insertion or removal of slides into and from the containers.

Abstract: This invention pertains to an apparatus for automatically assembling elements of a COAST container. The apparatus includes a cabinet that has a vertical stocker mounted therein for holding the elements of the COAST container, an input loadlock mechanism for introducing the elements into the cabinet, a manipulating mechanism for placing the elements into the vertical stocker, a conveyor located outside of the cabinet, a load loadlock mechanism mounted inside the cabinet and interfacing with the outside thereof near the conveyor, an automatic manipulator mechanism inside the cabinet for removing the elements from the vertical stocker and assembling these elements into the COAST container, and a mechanism for pressurizing the inside of the cabinet with a protective atmosphere.

Abstract: Disclosed is an automatic container assembler apparatus (800) to assemble the constitutive elements of a COAST container i.e. the wafer (138) that is to be treated in the manufacturing line, the cassette-reservoir (123) and the single wafer holder (130). In essence, the assembler apparatus consists of a cabinet whose interior space cabinet is submitted to a clean filtered gas flow generated by a blower, so that a clean gaseous mini-environment is created therein with a light overpressure with regard to the outside ambient. The cabinet includes a vertical stocker (804) adapted to be manually and safely filled with the adequate number of the elements mentioned above. Generally, the wafers are carried in a multiple wafer holder (130'). These elements are introduced in the cabinet through an input loadlock device (810) and laid down onto a table (806) by an operator. Next, the operator places them in their respective bins (815) of the stocker through manipulation gloves (805).

Abstract: A biological specimen cassette comprising a base and a lid wherein the lid has two pivotal connections, one at the front wall, the other at the rear wall of the base. The first pivotal connection allows a specimen to be placed in the base while the second pivotal connection allows the lid to be opened for removal of the specimen. Both pivotal connections serve to secure the lid to the base during storage of the specimen, but allow subsequent easy detachment of the lid from the base.

Abstract: The dispatching apparatus with a gas supply distribution system (300) basically comprises an automatic handler 301 and a vertical stocker (302).
