Title: Generic data and process base manager and data and process base management system for heterogeneous databases and process bases
Inventor: IOSSIPHIDIS JOSEPH
IPC: G06F17/30
Filed: 1993-03-02
Abstract: ABSTRACT             A procedural relation processing system is fundamental in managing distributed heterogeneous databases and distributed heterogeneous process bases, or application systems, at run-time, as they are perceived by theusers, directly at the time and place of perception. A procedural relation determines, as a unit, a variable combinational process and a variable structureoperand, to which the combinational process is applied. A structure operand can be any group of data existing in a database or any group of programming statements existing in a subroutine, or procedure, of an application system. A procedural relation processing system is fundamental in distributed heterogeneous databases and distributed heterogeneous process bases since it canrepresent and process any data or process structure. A user can express a procedural relation on the terminal or in a application program, as it is perceived by the user at run-time, directly at the time and place of perception. A procedural relation processing system, consisting of an Open Data and Process Model (ODPM) and associated management system components will be referred to as an Open Data and Process Base Management System (ODPMS). The ODPMS, accepts as input, the procedural relation. After analyzing its syntax and semantics, theODPMS transfers control to the location on the network where the data exists, identifying to the remote application system what statements to execute. These statements issue a request to their local Data Base Management System (DBMS). After receiving the required data values, the remote application system returns the data values to our local area and these values are displayed on the terminalby the ODPMS.

Title: Multiple access communications systems
Inventor: DELANEY DAVID M
IPC: H04L12/801
Filed: 1993-04-13
Abstract: ABSTRACT               Apparatus and method of communicating data signals in tree shaped networks suitable for use as a high speed local area network that allows the use of synchronous point to point transmission channels; that employs a multiple access technique in which a station or hub sends a transmission toward the root hub of the network only when the network hub to which it is attached solicits the transmission by use of an RTS/CTS protocol; that allows CTS transmissions to be made in the downward broadcast path; that provides fair, deterministic access to the network by station adapters; that provides for the detection and elimination of net-work traffic loops; provides a practical way of increasing network availability by introducing redundant network devices and redundant connections between them; and which allows transparent bridges to dis-tinguish and discard their own transmissions received from the network.

Patent CA-2095323-A1 (CA)
Title: Peptide binding assays with mhc antigens
Inventor: ROTHBARD JONATHAN B
IPC: C07K16/00
Filed: 1991-10-30
Abstract: Rapid, efficient, accurate assays are provided for measuring affinity of small molecular weight organic molecules and peptides to an MHC glycoprotein. The method employs a competition between a detectable agonist and the candidate of interest for an MHC  glycoprotein in solution or coupled to solid support, followed by detection of complex formation of the MHC glycoprotein and agonist.  The MHC glycoprotein may be preloaded with a second agonist to optimize the assay. Alternatively, the method employs the displacement of a preloaded, labeled peptide from the MHC glycoprotein by the candidate of interest. The level of agonist in the complex may be determined by the effect of the complex on sensitized T-cell proliferation.

Title: Gas lockout system
Inventor: NIMBERGER SPENCER M
IPC: F17C13/12
Filed: 1994-03-14
Abstract: GAS LOCKOUT SYSTEM                   ABSTRACT OF THE DISCLOSURE   A propane gas distribution system according to the present invention substantially enhances safety by providing a gas lockout device within the enclosure containing the distribution lines to the propane appliances for closing off a gas distribution line in response to either a sensed low pressure level or a sensed high pressure level. The closure member within the lockout device is biased closed, but is normally prevented from closing by a stop member which in turn is held in position until the unsafe low pressure or unsafe high pressure condition exists. A security control member is utilized for restricting the re-opening of the lockout device to select personnel, which typically would be a propane company representative. According to the method of the present invention, gas from the high pressure source is regulated and output to a low pressure gas distribution line. The gas pressure within the distribution line is sensed, and the gas line is automatically closed in response to a sensed low pressure level or a high sensed high pressure level. The gas distribution line is normally prevented from closing when gas pressure is above the low pressure level and below the high pressure level.

Patent CA-2126414-A1 (CA)
Inventor: LANDECK HARRY A
IPC: A45C13/10
Filed: 1994-06-21
Abstract: The present invention features an apparatus and method for extending, position sensing and folding the ties of a tie bag into the body of the bag. The apparatus and method of the invention accomplish the position sensing end folding of the ties as the webbing of the bag is rapidly moving. The ties are first extended and then folded within the web on-the-fly. The ties of the flexible web are caused to pass between two extension plates, in which respective air nozzles are located. Air is transversely passed over the upper and lower webbing surfaces via the nozzles. In so doing, the flexible ties are caused to flatten, smooth and extend perpendicularly to the direction of travel of the web. The air under pressure also prevents the ties from contacting the walls of the plates. The extended ties are now oriented so as to be acceptable to both the sizing and folding operations.
