Abstract: The present invention relates to a measure for minimizing an undesired passage of fluid from a first sector (1) to a second sector (2) separated by a non-fluid-tight separation (3), wherein a first pressure (P1-1) prevails in the first sector (1) and a lower second pressure (P2-1) than the first pressure (P1-1) prevails in the second sector (2). An intermediate chamber (4) which separates the two sectors (1, 2) from one another is arranged at the separation (3). A conveyor mechanism (5) is further provided which is designed to convey fluid from the intermediate chamber (4) to the first sector (1) in order to generate a lower pressure in the intermediate chamber (4) than the first pressure (P1-1) prevailing in the first sector (1), wherein the pressure (P4-1) generated in the intermediate chamber (4) is just as high or higher than the second pressure (P2-1) prevailing in the second sector (2).

Abstract: A vertically-adjustable work station is described. The work station includes a housing, a vertically-adjustable column, a work surface attached to the top of the column, and a motor to move the column vertically. In one embodiment, the work station is completely supported by a wall. In another embodiment, the work station is free from floor support.

Abstract: A toy train is provided having a folding body with body segments joined by a hinge, adapted to engage a base having wheels. The folding body may be disassembled for storage in a generally flattened arrangement. A novel drive assembly for a toy train or toy train accessory is provided having a motor and a gear, which can be removably inserted in the base and covered by the folding body. A storage kit is provided including a storage case for storing a folding body of a toy train, a base for a toy train, and a drive assembly for a toy train. A toy train set is provided including tiles with raised train tracks. The tiles are joined by dovetail joints. Themed tiles are provided for creating a multi-themed play environment.

Abstract: A retainer and support device for a food item, e.g., a jawbreaker, includes a housing having a recessed wall defining a chamber for receiving the food item. A passageway extends through the recessed wall and a product engaging member extends through the passageway and into the chamber for engaging the surface of a food item retained in the chamber. A manually actuatable drive member is in driving communication with the product engaging member to move the product engaging member and thereby move the food item retained within the chamber.

Abstract: The combination of a dispenser and a strip of a food product and a method for dispensing the food product from the dispenser so that it can be used by a user of the dispenser. The strip comprises an elongated web of an edible material, e.g., gum, which is coiled up in a compact configuration having a free end portion. The dispenser comprises a housing for the strip, an outlet, a motor for advancing a desired length and most preferably any desired length of the free end portion of the strip out of the outlet, and a severing element for severing the desired length of the free end portion of the strip from the remaining portion of the strip to form a dispensed section of the strip which may be placed in the user's mouth while the remaining portion of the strip remains within the housing.
