Title: Method and apparatus for buffering data in a multi-beam optical disk reader
Inventor: DAHAN SHALOM
IPC: G11B20/12
Filed: 1999-09-21
Abstract: Methods and apparatus are disclosed for buffering and reordering data blocks  read simultaneously from multiple tracks of an optical disk, so that they ma y be delivered in sequential order to a host computer. The methods involve the  use of numerous processes to receive read commands, position an optical pickup, handle memory management tasks, process data blocks as they arrive, and send data blocks to the host computer in sequential order as they become  available. The reordering of data blocks is achieved by checking each data block as it arrives in a "read process" to see if it may be linked in a sequential chain with a data block that arrived from the next track. Additionally, methods for determining if a requested data block is in the range of blocks that are currently being read, and methods for determining when the optical pickup may be moved to read the next set of tracks are described.

Title: Hinged top rail for above-ground pool and method of pool assembly using same
Inventor: SOBEL RICHARD M
IPC: E04H4/00
Filed: 2001-06-29
Abstract: A frame for portable above-ground swimming pools and, more particularly, a frame for above-ground swimming pools having a top rail, formed in sections, that is pivotally attached to the frame vertical supports. Each top rail section is installed at the top of the vertical supports in a vertical position that is about 90° from a horizontal axis, allowing access to the interior area of the pool frame for installation and attachment of the sheet metal swimming pool wall. Once the top rails sections are assembled, the frame is free-standing and the pool wall may be installed and attached to the frame without partial disassembly of the frame or removal ;end replacement of the top rail sections. Once the swimming pool wall and liner are installed, the top rail sections are rotated 90° along the horizontal axis, securing the wall and liner, and are locked into place. The invention further provides a method for installing an above-ground swimming pool in the sequential steps described above.

Title: Airplane cabin overhead air outlets
Inventor: SITLER GLENN
IPC: B64D13/00
Filed: 2001-06-22
Abstract: Passenger cabin ventilation air outlets located in the cabin ceiling blow air downward toward the passengers. An outlet for this location utilizes a series of high velocity jets exiting from a narrow ceiling nozzle to entrain cabin air to form a broad slow moving single jet. Three rows of slots are utilized, the outer rows to initially produce a wide air jet, and the center row to draw the outerjets back together outside of the nozzle. The center jets coalesce the outer jets into a slower moving total air stream.

Title: Method of powder coating
Inventor: PIDZARKO DENNIS
IPC: B05D7/06
Filed: 2001-12-10
Abstract: A method of powder coating at least one surface of a non-conductive object having a plurality of sequential steps.      The first step is pretreating the surface of the non-conductive object to ensure that the surface is suitably cleaned. The second step is to apply a sufficient quantity of moisture on the surface of the non-conductive object to facilitate adhesion of a powder coating to the surface. The next step is to spray a polymer coating powder on the moistened surface of the non-conductive object. This spraying step is done immediately following the application of moisture but prior to a complete evaporation of the applied moisture. The fifth step is to evaporate any remaining applied moisture from the non-conductive object prior to curing. The last step is to cure the coating on the surface of the non-conductive object without decomposing the powder and then either cool or allow the non-conductive object to cool naturally.

Title: Arcuate bulk storage facility
Inventor: STAFFORD BRIAN T
IPC: B65D88/02
Filed: 2001-12-18
Abstract: An arcuate structure for bulk particulate solids which has inner and outer concentric containment walls. The space between the inner and outer walls is subdivided into a plurality of storage subspaces, and covered with a continuous roof. A radial stacker conveyor system receives particulate solids to be stored, and transfers these particulate solids into a selected storage space through access apertures disposed on a circular arc in the roof. To allow the radial stacker to access each roof aperture, it is rotatable about an axis concentric with the inner and outer walls, and the roof apertures are located on an arc concentric with the inner and outer walls. A separate radially located conveyor system is provided beneath the floor of each storage space, by means of which particulate solid stored in any chosen storage subspace can be retrieved through discharge gates located in the floor of each storage space above the conveyor, and transported to a delivery system adjacent to the radial stacker. The length of arc used for the structure is largely determined by the available space, and the chosen delivery system. Typically the arc length will be about 180°, and can be 360°. Since the storage spaces and the conveyor systems can all be enclosed, localised pollution is minimised. Further, since all of the storage spaces are protected by a roof, the effects of weather on the stored particulate materials is substantially eliminated.
