Title: Furrow closing device
Inventor: MARTIN HOWARD
IPC: A01C5/06
Filed: 1994-11-04
Abstract: ABSTRACT    A seed furrow closing device for planting units including a plurality of closing wheels, each wheel having a plurality of sharpened teeth on the periphery.  The closing wheels canted at an angle to the vertical and press toward the seeds in the furrow.    The teeth, controlled by down pressure mechanism, penetrate the soil to till compacted soil and firm loose soil to improve germination and emergence.  The sharpened teeth interact with the soil to remove residue from the teeth as the teeth emerge.  The penetration of the teeth helps break up clods and also stabilizes the rear of the planting unit.    A trailing press wheel over the furrow may provide intermittent compacting of the soil loosened by the closing wheels over the center of the furrow.    This loosening and compaction by the sharpened toothed wheels improves the germination and emergence of the seeds in the furrow.

Title: Method of preferential labelling of phycobiliprotein with amine-reactive dye for use in a multiple color assay
Inventor: GUPTA RAVINDER K
IPC: C07K14/415
Filed: 1993-08-27
Abstract: A  method  for  preparing  phycobiliprotein/amine-reactive  dye conjugates  is  disclosed  in  which  the conjugates    so   prepared   overcome    the    energy transfer/fluorescent quenching dilemma encountered in the use of prior art conjugates.   A phycobiliprotein,  for example, phycoerythrin or allophycocyanin, is conjugated with an amine-reactive dye, for example, Texas Red or carboxyfluorescein succinimidyl ester, in the presence of a   selective   salt   which   causes   a   hydrophobic intramolecular  rearrangement  of  the  phycobiliprotein thereby exposing more hydrophobic sites for binding to the  amine-reactive  dye.     The  conjugates  prepared according to the invention are useful in multiple color fluorescence assays without requiring the use of multiple exciting sources.

Title: A Method for Validating a Communication Link
Inventor: SCHELLINGER MICHAEL J
IPC: H04B1/38
Filed: 1995-03-09
Abstract: The method of the present inven-tion generally validates a communication link in a communication system. In par-ticular, the method validates a communi-cation link between a cordless base sta-tion and authorization and call routing equipment by authenticating the cordless base station to communicate with said au-thorization equipment (603) and authen-ticating the authorization equipment to communicate with the cordless base sta-tion (604). Preferably, the step of au-thenticating the cordless base station is based upon a first random number gener-ated within the authorization equipment (502) and the step of authenticating the authorization equipment is based upon a second random number generated within the cordless base station (504). A com-mmunication link is allowed between the cordless base station and the authoriza-tion equipment when both the cordless base station and the authorization equip-ment have been a authenticated (614).
Patent CA-2166302-A1 (CA)
Title: System for object oriented dynamic linking based upon a catalog of registered function set or class identifiers
Inventor: COWSAR GEORGE CURTIS
IPC: G06F9/445
Filed: 1994-06-30
Abstract: A system is provided for managing code resources for use by client applications in a computer, wherein the computer has internal memory storing at least one client application. The apparatus comprises a resource set catalog stored in the internal memory. The resource set catalog identifies a plurality of function sets of functions by respective function set IDs. Further, the resource set catalog includes set records which characterize the functions within me respective sets. A dispatch engine, in the internal memory, linked with a client application, supplies a particular function set ID in response to a call by the client application of a particular function which is a member of a corresponding function set identified by the particular function set ID. A lookup engine in the internal memory, coupled with the resource set catalog and the dispatch engine, is responsive to the particular function set ID to look up a set tad for a corresponding function set in the resource set catalog. Finally, a link engine in the internal memory and coupled with the dispatch engine returns the particular function to the client application in response to the set record. Thus because the link engine is responsive to the set record, which is not linked with the client, the client need not be aware of changes in the structure of the library in which the particular function set resides. Thus, the function set can be moved into and out of internal memory, revised placed in different sections of internal memory, and otherwise handled independently of the client, without requiring re-compilation of the client application.

Patent CA-2167135-A1 (CA)
Inventor: SCHAFFNER LAREY D
IPC: F04B49/00
Filed: 1996-01-12
Abstract: A torque limiter control sets the limit of power which may be absorbed by a pump. A feedback system adjusts the displacement in the pump in response to changes in the pressure of working fluid at the pump outlet to maintain a set power. A torque limiter set adjustment applies a torque setting force to a vent spool to bias the vent spool against a vent port to thereby seal the port. As working pressure fluid increases, the force of the fluid acting on the vent sleeve ultimately overcomes the setting of the torque limiter and commences to pull which in turn permits fluid to flow through a compensator metering spool to thereby change the displacement of the pump.
