Title: Database link system
Inventor: EMERSON MICHAEL GENE
IPC: G06F17/30
Filed: 1994-10-24
Abstract: A system to enhance query performance. The query is performed on a modified database in which data entries for each field are stored contiguously across all records. The query is parsed (32) into portions directed to each field referenced by the query. Each portion is searched over the contiguous entries of the appropriate data field. A bitmap is generated (36) by producing a string of bits, each bit representing a record and setting bits corresponding to records that satisfy the query. The resulting bitmaps are combined (38) to produce the results of the original query. The preferred embodiment is a direct marketing database on a client server system using a spreadsheet like interface for query manipulation. Data segmentation, ad hoc requests and systematic research are allowed. A suite of reports specific to the needs of direct marketers may be produced on a regular basis.

Title: Shared distribution of internal message storage facilities by a plurality of communication terminals
Inventor: PETTY NORMAN W
IPC: G06F13/00
Filed: 1996-07-24
Abstract: Initially storing multimedia messages from an originating communication terminalto a destination communication terminal on the destination communication terminal. If the destination communication terminal cannot store messages, then the message is stored on the originating communication terminal. The destination communication terminal may not be able to store messages because it no longer has present message storage facilities on an internal storage unit or it does not have any internal storage capability for messages.  Similarly, the originating communication terminal also may have exceeded its capacity to store messages or may not have any internal storage devoted to the storing of messages.  The destination communication terminal maintains a list of messages that are stored on other communication terminals.  In addition, if the originating communication terminal cannot store messages, a message is stored on a third terminal which has the capacity to store messages. The messages stored on the third communication terminal are encrypted to protect the privacy of users of the originating and destination communicationterminals.

Title: Vapor-liquid contact tray and downcomer assembly and method employing same
Inventor: YEOMAN NEIL
IPC: B01D3/16
Filed: 1995-04-06
Abstract: A  vapor-liquid contact tray (18) and downcomer (24) assembly is provided with louvres (32) which serve to impart a horizontal directional flow to the liquid exiting the downcomer and/or the vapor passing through the tray. The downcomer includes a bottom plate (30) which closes the outlet region of the downcomer and includes a plurality of louvres (32) presenting generally vertical openings in the direction of liquid flow across the underlying tray. The downcomer receiving area (34) in the underlying tray can include similar louvres (36). The louvres redirect the vertical momentum of the liquid and vapor streams to a generally horizontal momentum as the liquid exits the downcomer and as the vapor rises through the tray. In other embodiments, the louvres in either the bottom plate or the downcomer receiving area of the tray are replaced with apertures which do not block the vertical momentum of the stream passing through the apertures. An enhanced vapor-liquid active area on the tray results from the use of the louvres.
Patent CA-2185829-A1 (CA)
Title: Two-dimensional modulation for line screen printing
Inventor: VENKATESWAR VADLAMANNATI
IPC: B41J2/52
Filed: 1996-09-18
Abstract: An improved method of line screen printing. Instead of screening the image with only one set of lines, the image is also screened with a second set of lines, which are substantially orthogonal to those of the first set. The screening is accomplished with two types of cells, horizonal cells and vertical cells. The pixels are classified according to their distance from the nearest line in the horizontal cells. This process is repeated with respect to the vertical cells. Different tone curves, which map input pixel values to output pixel values, are associated with different pixel classifications. In general, pixels closer to lines have tone curves that map to higher output values. Because each pixel is in both a horizontal cell and a vertical cell, each pixel has two values from the tone curves. For each pixel, its two tone curve values are combined to obtain a greyscale value for that pixel.

Patent CA-2193328-A1 (CA)
Inventor: MONROE ROBERT C
IPC: B29L31/00
Filed: 1996-12-18
Abstract: A method of and apparatus for molding hollow items using the resin transfer molding technique in such a manner that the resin is more uniformly distributed about and along the molding region of the mold.   This is accomplished by installing oppositely spaced grooves in the mold and injecting resin directly into these grooves.  Upon such injection, the resin travels along and fills the groove (by taking the path of least resistance) before such resin is squeezed or forced out a minute gap that exists between the molding surfaces and into the molding region of the mold.  As such resin is being forcibly injected into the cloths in the mold, a vent permits any air displaced from the cloths by the resin to be released.  Such resin injection and mold venting occurs until such time that no more air is vented and instead 100% resin  is being discharged from the mold.   Upon this occurrence, further resin injection is curtailed and the resin previously injected is allowed to harden and cure.  A disposable pressure bag distributes the molding pressure created by the injected resin equally within the mold.  Thus, this pressure bag enables a high quality void-free plastic laminate to be made.          A means of pressurizing this bag while maintaining a seal that prevents any loss of resin is also disclosed.

Title: Flow control weir valve
Inventor: SARGENT RONALD J
IPC: E04H4/12
Filed: 1995-10-27
Abstract: A flow control weir valve and method of operating the valve is disclosed. The valve has an inlet (12), an outlet (14), a bypass inlet (16), a pivoting cover (20) and a mechanism for controlling the cover in order to provide a relief flow through the valve. The cover is continuously forced to a first, closed position by one or more resilient springs (21) or other flexible force producing mechanisms. When fluid flows within the valve, the closing force generated by the springs may be overcome by the low pressure generated within the valve, which thus allows the ambient environment to force the cover at least partially open once the fluid flow rate passes a threshold value. A step (40) in the body of the valve can be used to interrupt the fluid flow and create a Venturi effect for further assisting the cover to open. The cover is sufficiently responsive to allow a relief flow through the bypass inlet that satisfies rapid and wide-ranging pressure variations created within a cleaning system to which the valve may be attached. Additionally, the valve may be located so that the fluid ingested through the bypass inlet creates a skimming effect that draws debris found on the surface of the liquid in which the valve may be located into the cleaning system through the bypass inlet.
