Patent CA-2197324-A1 (CA)
Title: Scalable distributed computing environment
Inventor: GREGERSON DANIEL P
IPC: H04L12/56
Filed: 1995-08-18
Abstract: The present invention relates to disbributed computing systems and is more particularly directed to an architecture and implementation of a scalable distributed computing environment which facilitates communication between independently operating nodes on a single network or on interconnected networks, which may be either homogeneous or heterogeneous. The present invention is a dynamic, symmetrical, distributed, real-time, peer-to-peer system comprised of an arbitrary number of identical (semantically equivalent) instances, i.e., kernels, that together form a logical tree. The kernels exhibit unified and consistent behavior at run time through a self-configuring and self-maintaining logical view of the network. Each kernel resides at a network node that has one or more resources associated with it. The kernels dynamically locate one another in real-time to form and maintain a hierarchical structure that supports a virtually unlimited number of independently running kernels. The system maintains its logical view of the network and user-developed programmatic resources regardless of the number and combinations of transport protocols and underlying mix of physical topologies.  The system's communications services utilize a dynamic context bridge to communicate between end nodes that may not share a common transport protocol stack, thereby allowing applications residing on different stacks to communicate with one another automatically and transparently.

Patent CA-2205752-A1 (CA)
Title: Windrow deflector plate for a round baler
Inventor: VOSS DON
IPC: A01F15/10
Filed: 1997-05-21
Abstract: The invention provides an improvement to the feed path for conventional belt round balers in the agricultural industry, and reduces the jamming of baling material in the feed gap of the baler. In a commonly known round baler the baling material enters the bale forming chamber through a feed gap defined by an upper roller and rotating away from the bale forming chamber, and a lower roller and rotating towards the bale forming chamber. As the upper roller is moving counter to the flow of baling material into the bale forming chamber, baling material which contacts them is retarded, and tends to form a ball of material which can plug the feed gap. The present invention provides a plate covering the upper roller which plate deflects the baling material into the feed gap and prevents the baling material from contacting the upper roller. The invention could be provided as an integral flange manufactured in new balers, or could be produced as a mountable plate for retrofitting of existing equipment.
Patent CA-2206919-A1 (CA)
Title: Hydromechanical control for a variable delivery positive displacement fuel pump
Inventor: GAUDET TIMOTHY J
IPC: F02C9/38
Filed: 1997-06-04
Abstract: A hydromechanical control system for a variable delivery, positive displacement fuel pump includes a variable area orifice metering window through which fuel from the pump outlet passes on its way to a gas turbine aircraft engine.  The fuel pressures on either side of the fuel metering window are ported to corresponding sides of a spool of a pump control valve.  The position of the valve spool controls the fuel flow to either side of a pump control actuator, whose movement varies the displacement of the pump.  A bypass fuel flow upstream of the fuel metering valve is also ported to the pump control valve.  During steady-state pump operation, a relatively small and constant value of fuel flow is bypassed through the pump control valve and back to the pump inlet.  However, upon increasing or decreasing pump speed transients, the bypass fuel flow is increased or decreased in a proportional amount.  In this way, improved control of the pump during transient conditions is achieved.

Title: Keyless entry systems for use with conventional locksets
Inventor: CACIOPOLI DOMINIC
IPC: E05B47/06
Filed: 1997-10-06
Abstract: A keyless entry system for use with conventional locksets is provided.          The system employs a battery operated motor and a gear train mounted on the inside of a door. The motor and gear train rotate the inside handle of the lockset in the same manner as a user would rotate the handle to unlatch the door. Misalignments between the gear train and the lockset are accommodated by a pawl which connects the gear train to the connecting shaft between the lockset's inside and outside door handles. The electric motor is activated by a control system responsive to a RF signal generated by a transmitter pendant carried by the user. The RF signal includes a user code, and the control system has a learning mode and an operating mode, with the learning mode serving to record a list of one or more authorized user codes and the operating mode employing that list to determine if the door should be unlatched in response to a particular user code.

Title: Apparatus and method for detection of leaks in surgical drapes
Inventor: LICATA MARK
IPC: A61B19/04
Filed: 1996-05-02
Abstract: The present invention is directed to a method and apparatus for preventing damage to drapes and to heating and cooling mechanisms used in conjunction with apparatus for containing and thermally treating sterile liquid, and to preserving the sterile field when using such apparatus. A surgical drape (17) is combined with a sensor (14), preferably attached to the drape (17), to detect whether or not liquid is present in a drape container conforming to a heating/cooling basin (11). An alternative embodiment employs sensors at opposite surfaces of the drape to measure conductance and, thereby, leakage through the drape. A microprocessor in each embodiment receives a signal representing, for example, an electrical conductance measurement from the sensors and determines if liquid is present, or alternatively if the conductance is sufficient to represent the presence of a leak.
