Title: Combined multi stage flash-multi effect distillation system with brine reheat
Inventor: FATH HASSAN E S
IPC: C02F1/06
Filed: 1996-11-14
Abstract: A new Multi Stage Flash (MSF) distillation system of enhanced flashing, brine reheat and superimposed Multi Effect (ME) distillation system (named herein as: Combined MSF-ME System With Brine Reheat) is disclosed. The invented system has special features designed to increase the distillation unit capacity and production rate, and improve its performance. The invented system uses a combination of: i) the up-to-date (proven design) MSF system as a base system with different methods to improve the flash chamber effectiveness (non-equilibrium factor) and flashing evaporation rate; ii) increases the MSF system flashing range through brine reheat, i.e. supply (all or part of) the brine with additional (external) heat in brine reheaters (located after the brine heater and/or within the flash chambers), and; iii)superimposes the ME distillation concept and system on the MSF base system. The invented system utilizes the mainfeatures and advantages of both MSF and ME systems simultaneously, and operates within the existing (proven design) system's constraints and limitations. The invented system allows, also, for the possibility of utilizing waste heat as the externalheat-source for brine reheat. The invented system, therefore, presents a break-through for the future generation of saline water desalination systems of higher capacity, better performance and lower water production costs.

Title: System and method for transmitting a displayable message to a short message entity in more than one data package
Inventor: AYABE BENSON S
IPC: H04W28/14
Filed: 1996-11-14
Abstract: A system (100) that is capable of transmitting a displayable message to a short message entity (102, 104, or 105) in more than one data package over a conveying network. The system (100) uses a capacity determiner (206) to determine a capacity of the conveying network for transmitting data. Based on this capacity of the conveying network, a fragmenter (204) divides the displayable message into fragments at an application protocol layer. The size of a fragment does not exceed the capacity of the conveying network. Finally, a packager (208) packages the fragments into data packages. The data packages are operable to be separately transmitted by a short message service over the conveying network. The data packages may include a reference parameter corresponding to the position of the fragment in the displayable message. Further, a reference parameter may indicatethe total size of the displayable message being fragmented and packaged. When all of the fragments of the displayable message are received at the terminating short message entity (102, 104 or 105), a fragment retriever (304) retrieves the fragments. A message reconstructer (306) reconstructs the displayable message. The displayable message is then passed a disposing device (308). (FIG. 1)

Filed: 1997-07-09
Abstract: An implantable medical device such as a stent may be implanted within a patient by the steps of advancing a catheter having a balloon into the patient, in which the catheter carries the medical device in a position surrounding the catheter balloon. The catheter also carries an outer, semi-flexible sheath surrounding at least part of the catheter and the medical device.      The medical device and flexible sheath are advanced together into a patient with the catheter, to position the device at a desired location while the device is enclosed in the sheath. Then, the sheath is retracted to expose the medical device to the exterior. The balloon is inflated to radially expand the device. Then the catheter and sheath are withdrawn from the patient. The catheter described can be used to implant a stent without the need for a guiding catheter. Also, x-ray contrast media can be applied to the vicinity of the medical device without removal of the guidewire.

Title: Composite wood flooring
Inventor: VANGILDER JAMES N
IPC: B32B21/08
Filed: 1996-06-06
Abstract: A fiber reinforced composite wood flooring is designed particularly for use in van-type truck trailers which experience adverse operating conditions due to heavy lift truck traffic on the top side and water spray during rainy periods on the bottom side. The composite wood flooring comprises edge-glued laminated wood boards (16) which are underlaid with a thin fiber reinforced plastic (17). The top surface of the composite wood floor is the same as that of a conventional laminated wood floor. The fiber reinforced plastic underlay is composed of glass and/or carbon fibers embedded in a polymeric resin such as epoxy, phenolic or vinyl ester. The resin holds the glass fibers together and also bonds the reinforcements to the laminated wood boards. The reinforcement is designed to enhance the mechanical properties of the flooring in the longitudinal and transverse directions of the floor and also to provide better bonding to the wood. The fiber reinforced plastic improves the fatigue resistance of the composite wood flooring and prevents water leakage into the trailer through the floor boards. The composite wood floor board may be fastened with fasteners (13) to cross-members having an I-section (14).
