Title: Communication dma device
Inventor: ISHIBASHI HIDEKI
IPC: G06F13/28
Filed: 1998-05-14
Abstract: A communication DMA device having temporary storage for temporarily storing data to be transferred and an output for outputting several bits of data simultaneously is disclosed. The DMA device also has a register for storing information indicating an area of the memory in which data to be transmitted is stored, the capacity of the data to be transmitted, and an indication of the start of communication. A bus switching request requests the CPU to release the data bus, allowing the data, having a prescribed bit width, to be read from memory. The switching request circuit immediately reconnects the data bus to the CPU after termination of the data transfer. Based on the information stored in the register means, the data read from memory via the data bus is temporarily stored in a temporary storage circuit. The temporarily stored data is divided into several units, such as 8 bit units, which are output serially via the communication circuit.  The communication DMA device frees the CPU from the data bus and performs communication control and transmission of data, thereby reducing CPU load and also allowing high-speed data transfer.

Title: Wobble piston and seal assembly for oil free compressor
Inventor: WOOD MARK W
IPC: F04B39/04
Filed: 2000-01-19
Abstract: An improved wobble piston and seal assembly for an oil free air compressor. The piston has a seal support surface which is provided with an upwardly directed curve adjacent its perimeter. A flat annular seal is secured to the piston to be supported by the support surface. The curve imparts a limited bend to the seal adjacent the perimeter of the piston. The piston and seal are then inserted into a cylinder which increases the bend to substantially 90°. The region of the bend in the seal adjacent the top of the piston is supported by the curved top to reduce flexing during operation at high air pressures. By preventing a reduction in the bend radius at high air pressures, stress in the seal at the bend is reduced, permitting use of a harder more durable seal material.
Patent CA-2296392-A1 (CA)
Inventor: SALAMINI FRANCESCO
IPC: C12N15/81
Filed: 1998-07-13
Abstract: The invention relates to the characterization and use of powerful viral promoters for expressing genes in bacteria and fungi, especially yeasts. The invention is based on a surprising discovery, namely that CFDV-DNA (DNA of the coconut foliar decay virus) and fragments of CFDV-DNA contain a region active as promoter even in bacteria and fungi, especially yeasts, although they originate from a virus which infects monocotyledonous plants. The activity of these promoters in E. coli is markedly greater than that of the CaMV 35S promoter which is also active in bacteria.

Title: Process for heat integration of an autothermal reformer and cogeneration power plant
Inventor: SHINNAR REUEL
IPC: F02C3/28
Filed: 1998-06-18
Abstract: A process for integration of an autothermal reforming unit and a cogeneration power plant in which the reforming unit has two communicating fluid beds. The first fluid bed is a reformer reactor containing inorganic metal oxide and which is used to react oxygen and light hydrocarbons at conditions sufficient to produce a mixture of synthesis gas, hydrogen, carbon monoxide, and carbon dioxide. The second fluid bed is a combustor-regenerator which receives spent inorganic metal oxide from the first fluid bed and which provides heat to heat the inorganic metal and balance the reaction endotherm, by combusting fuel gas in direct contact with the inorganic metal oxide producing hot flue gas. In preferred embodiments, steam is also fed to the reformer reactor and a catalyst may be used with the inorganic metal oxide. The cogeneration power plant has a gas turbine equipped with an air compressor and a combustor and in the integration a portion of compressed air is drawn off from the power plant gas turbine air compressor leaving remainder compressed air; the drawn off compressed air is introduced to the combustor-regenerator; the hot flue gas from the combustor-regenerator is mixed with the remainder of the compressed air to produce a recombined gas stream and this recombined gas stream is fed to the combustor of the cogeneration gas turbine power plant.

Inventor: MACKAY ROBIN
IPC: G06N7/02
Filed: 2000-08-31
Abstract: An expert system and a method of providing automated advice are described. The system is regularly updated by advice (or diagnosis, recommendation etc.) given by practitioners in the relevant field. The combination of the underlying facts and the consequent (human) advice is used to update a ruleset that is then used to provide automated advice. An example of financial advice is given. A database contains the details for the customers of a financial institution together with advice and recommendations given previously by the institution's human advisors. This database is used to derive a ruleset which is then applied to a subsequent customer's details in an automated manner, possibly at the user's own PC via the World Wide Web. Frequent updating using data from the human advisors' work means that the database (and hence the ruleset) are kept up to date.      Consistent advice can thus be provided with minimum human interaction.

Title: Vent system for an axle and hub assembly
Inventor: DAVISON KENT
IPC: B60B35/00
Filed: 2000-11-22
Abstract: A vent system for a wheel hub comprising a first filtered vent at the wheel end cavity and a second vent formed by a one-way, pressure relief valve venting the axle tube to atmosphere. The vent system defines a vent path from the wheel end cavity through a first, preferably filtered, vent into the axle tube then through a second check valve connecting the axle tube to atmosphere. A porous material is positioned to cover the vent passage at the wheel end cavity for allowing a flow of gases to enter and exit the vent passage while preventing liquids and other contaminants from traveling therethrough. The porous material is held inplace over the vent by a snap ring or other suitable retention means disposed within the vented plug member. The second axle tube vent is disposed along the axle tube to vent the tube itself to atmosphere with pressure relief.
