Title: Electromagnetic reservoir heating with vertical well supply and horizontal well return electrodes
Inventor: YU C LAWRENCE
IPC: E21B43/30
Filed: 1994-04-08

Abstract: A process is taught for production of Mo-99 from uranium-235 and for managing waste produced therefrom. The process includes separation of the Mo-99 from irradiated uranium and solidification of the waste remaining after such separation. Because of the great reduction in the amounts of waste produced fromthe process over previous methods, the process is of particular use in the large-scale production of Mo-99. Further, the present process results in a reduced process time over previous processes and thereby offers a reduction in the loss of Mo-99 by decay.

Abstract: A nanofiltration process using a conventional nanofiltration membrane module under a positive applied pressure is used to selectively change the concentration of one solute, such as sodium chloride or sodium chlorate providing monovalent ions, from another solute such as sodium sulfate or sodium dichromate providing multivalent ions in high salt aqueous concentrations. The process is particularly useful in favourably lowering the concentration of silica and dichromate ions in chloral kali and chlorate brine containing solutions and favourably raising the sodium sulphate level relative to sodium chloride in chloraldhali liquor. The relatively high salt concentration, surprisingly, effects little or no monovalent, particularly, Cl rejection.

Abstract: The mechanism is used for rotating a tree-felling implement rotatably connected to a distal end of a boom of  a  logging  vehicle  by  an  implement  pivot.  The mechanism  comprises  a  first  arc-shaped  member  that extends in a plane perpendicular to the boom plane and is convex with reference to the implement pivot. The first member has a first end rotatably connected to the frame of the implement at a given distance from the implement pivot. A second arc-shaped member, coplanar with the first member, is also convex with reference to the implement pivot. The second member has a first end rotatably connected to the second end of the first member for defining an intermediary junction,  and a second end rotatably connected to the distal end of the boom. A hydraulic actuator is mounted on the frame of the implement and has an end rotatably connected to or adjacent to the intermediary junction for rotating the implement  during  operation  of  the  actuator.  The mechanism provides a simple and reliable construction for rotating a tree-felling implement that is capable of rotating the implement with reference to the boom plane in both directions and according to a wide range of angles.

Title: Simplified bar code decoding method
Inventor: WANG YNJIUN P
IPC: G06V30/224
Filed: 1995-09-14
Granted: 2007-07-31
Abstract: The reading and decoding of two- dimensional bar codes in a bar code reader are simplified and field loading of different data character sets is en- abled. Decoding of bar/space patterns of a bar code is simplified by deriving T-sequence data representative of the bar/space pattern and then processing a majority of the T-sequences directly into decoded values representative of the bar/space pattern. Dynamic load- ing of new data character sets fully or partially superseding a factory installed default character set correlation listing is enabled by use of loadable correla- tion listings keyed to foreign language characters, symbols, words or phrases relevant to particular applications. The loadable correlation listings can be en- coded into a two-dimensional bar code and laoded via a reading of the bar co de by the bar code reader.

Abstract: A water circulation apparatus to provide instant hot water to faucets remote from the heater in residential and small commercial buildings when water is periodically used in the building.  The apparatus comprises a body containing an aspirator and a check valve, and provisions for installation in the water supply line to the heater and cold water faucets. It uses a small water return line from a tee installed in the hot water pipe near the remote faucet, to a connector on the water circulation unit, thereby establishing a circulation loop from the water heater, through the hot water pipe, the tee and return line, and through the water circulation unit back to the heater. The aspirator is a tapered bore in the body with a concentric nozzle positioned in the large end, and a low pressure tap located in the vicinity of the nozzle outlet. The check valve uses a neutrally buoyant poppet to minimize friction. The unit is responsive to the user and is self regulating in that it causes water to flow in the circulation loop only when water is being used in the building. Water is conserved since there is no need to run water to waste awaiting hot water from the heater to reach the remote faucet. When the building is unoccupied, the unit is dormant, thus conserving heat that would be lost if the pipes were kept hot at all times. The unit needs no gas or electrical power, and operates with only one moving part.

Title: System and method for runtime optimization of private variable function calls in a secure interpreter
Inventor: YELLIN FRANK
IPC: G06F9/45
Filed: 1996-11-27
Granted: 2003-05-06
Abstract: A secure program interpreter performs a special check the first time itexecutes a method call to determine if the sole purpose of the called method is to access the value of private variable, modify the value of a private variable, or return a constant value. When this is the case, the interpreter's internal representation of the method being executed is modified so as to directly access the private variable of the called method, or to directly accessthe stored constant of the called method. The modified method representation uses special "privileged" load and store instructions, not available in normal source code programs, that access private variables and constants outside the method being executed without causing a security violation to be flagged. When the modified portion of the method is executed, the private variable or constant is accessed directly by the executed method using a privileged load or store instruction, the use of which avoids the flagging of a security violation by the program interpreter. When execution of the program is completed, the modified internal representation of the method is flushed, such that when the program is executed again said interpreter generates a new working representation of the aforementioned method.
