Title: Engine crankcase ventilation system including a blowby gas passage defined between crankcase members
Inventor: SAYAMA TAKEHIKO
IPC: F01M13/04
Filed: 2000-01-27
Abstract: In an engine crankcase ventilation system, a blowby gas passage (25) and a fresh air passage (26) are defined between adjoining crankcase members so as to extend in parallel with a crankshaft axial line along either side of a lower part of said crankcase assembly. Because the crankcase is configured to receive the rotating crankshaft (7) provided with counterweights, it necessarily has a circular cross section. Therefore, this arrangement allows effective utilization of the available space. Thus, a cavity of a required volume for effective oil separation and pressure pulsation damping can be formed in the engine main body without increasing the number of components parts, and without complicating or increasing the size of the overall structure.

Title: Dual mode of operation fireplaces for operation in vented or unvented mode
Inventor: LYONS DAVID CHARLES
IPC: F24B1/18
Filed: 2000-03-01
Abstract: A novel dual mode of operation gas fireplace of the type having a combustion chamber box and a heat exchanger is provided with a burner in the bottom of the combustion chamber box which creates exhaust gasses to be passed out of the combustion chamber box and into or through the heat exchanger portion of the fireplace mounted on top of or back of the combustion chamber box. The hot exhaust gasses leaving the combustion chamber box may be directed into an exhaust stack or diverted directly into the room to be heated by a blower motor which diverts hot exhaust gas products from the heat exchanger directly into a room area to be heated in a ventless mode of operation. When the blower motor which diverts the exhaust gasses into the room is deactivated, the novel fireplace may be operated in a vented mode of operation. The feature of the present invention is that the novel fireplace may be operated in both the dual modes of operation simultaneously to achieve greater efficiencies than could be achieved by operating the fireplace in a vented mode of operation alone.

Patent CA-2304764-A1 (CA)
Title: Ophthalmic lens synthesized from its specifications
Inventor: THIEBERGER GIL
IPC: G02C7/02
Filed: 1998-08-31
Abstract: This invention relates to a novel prescription lens (58), mainly suited for ophthalmic applications. The lens designer defines the macroscopic surface of the lens (59, 60) as desired. The design process assumes that the location of the object (50), the lens (51), and the required image (53) are known. By using Ray-tracing technique we calculate the macroscopic normals to the lens that will form the required image. From those macroscopic normals we calculate the macroscopic surface by a process of summation of the slopes with geometric pattern conditions. The final surface is not smooth but contains plenty of dense macroscopic shapes that look like saw-teeth. The rough surface enables the lens to have almost any desired shape and thickness.

Title: Management of a telecommunications system
Inventor: THOMPSON JONATHAN ANDREW
IPC: H04Q3/00
Filed: 1999-03-19
Abstract: The present invention provides a management system and method for a telecommunications system, the telecommunications system having a plurality of objects representing elements of the telecommunications system and/or operations that may be applied to those elements. The management system comprises a management controller connectable to an item of telecommunications equipment of the telecommunications system for passing messages over a communications link between the management controller and a management element of the telecommunications system to invoke management operations. Further, the management system comprises means for defining a number of messages which may be generated by the management controller or the management element for passing over the communications link, each message being arranged to include one or more information elements. At least one of the messages is arranged to identify one of said objects as an information element and to cause different management operations to be invoked dependent on the object identified. By this approach, a separate message is not required for each management operation, and instead particular management operations can be invoked by virtue of the object specified within a particular message. This enables a simple generic interface to be provided between the management system and the telecommunicaitons system that is independent of the particular management functions that need to be performed on any particular telecommunications system. Hence, this enables the management system to be readily reused with different telecommunications systems without the requirement to alter the message interface between the management system and the telecommunications system.
