A cell tray has a multi-dimensional array of cells in precise, equally spaced wells (cubicles or silos) containing medium of interest. The ordered cell array enables automated processing as well as simultaneous monitoring and analyzing of a large matrix of cells, biological fluids, chemicals and/or solid samples. The invention is an integrated device and is fabricated into substrates similar to microscope slides. The ordered array of cells in precise locations helps in parallel analysis and proc...

The present invention is directed to systems and methods which use a tray to hold and transfer objects, such as produce. The tray has at least one opening to permit the user to manipulate the tray during transfer without touching the contents held within the tray. The tray has an open end with a curved edge to reduce damage to the contents when transferring contents from the tray to a container. The tray is preferably constructed from a plastic-like material.

A fiber tray is provided for installing fiber optic cable and other types of cable that are vulnerable to performance losses if a certain minimum bend radius is not maintained. The fiber tray allows a user to create a subassembly that maintains bend radius control while easing assembly. The construction of the fiber tray also minimizes the depth of the tray and gives freedom to the user to vary the routing patterns of the cable so that a component that is attached to the end of the cable can be ...

In a disc tray (T) having a tray main body (1) to which disc holders (3) are mounted at a plurality of portions in a periphery of a disc set portion, there are provided with a movable body (4) swinging the disc holder (3) through a push pull operation, and an operation knob (43) for pushing and pulling the movable body (4). A gear in a side of the disc holder (3) is engaged with a rack portion (42) in a side of the movable body (4)

A concession tray for selectively supporting concessions in a substantially horizontal position relative to a stadium seat, thereby facilitating the comfort and enjoyment of a patron at a performance or event. A retaining flange is coupled to the concession tray and easily integrated with an existing stadium seat such that the concession tray may retain concessions in a fixed relationship with a stadium seat without requiring substantial modification of the stadium seat, if any. The concession t...

An implant sterilization tray includes an integral torquing fixture for holding an implant stationary. By incorporating the fixture into the instrument tray, a large, stable base is provided for holding the implant. The user can more readily hold the implant in a stable position with the implant resting in the case and the case resting on a table.

An improvement in the immunofixation electrophoresis procedure for detecting proteins in serum, urine or cerebral spinal fluids. Multiple samples from a single patient are placed on a gel and subjected to electrophoresis for resolving or separating proteins. A container has multiple receptacles which store, separately, various antisera. The separate antisera are withdrawn from the receptacles and simultaneously applied to the sample areas for subsequent incubation. The receptacles are preferably...

An adaptable battery tray for supporting a battery includes a body having a pair of end walls and side walls, with each end wall rotatably attached to an adapter. The adapter is rotatable between a first position and a second position. In the first position, the adapters are external to the interior of the battery tray and permits the battery tray to support a battery having dimensions approximating the dimensions between the side walls and the end walls. When a battery of lesser length is to be...

A foldable tray having a single sheet of material having lines of reduced resistance to bending separating a central base area and first through fourth side areas encircling the base area, the lines of reduced resistance to bending separating the first and second side areas being curved away from each other adjacent a first corner of the base area to cause the base area adjacent the first corner to curve upward when the first and second side areas are bent upward along their respective lines of ...

A fireplace tray positionable on the floor of a fireplace to receive and collect ashes from burning logs in the fireplace. The tray has a collector portion which receives and collects the ashes, a rotatable support mounted to the collector toward a back wall thereof to roll the tray into and out of the fireplace and a front support mounted to the collector toward a front wall thereof to retain the tray in position in the fireplace. The fireplace tray preferably also includes handles mounted to t...
