Title: Catalysts and process for hydrogenolysis of sugar alcohols to polyols
Inventor: ZACHER ALAN H
IPC: C07C29/00
Filed: 2001-01-08
Abstract: The present invention provides a process for preparation of low molecular weight polyols from high molecular weight polyols in a hydrogenolysis reaction under elevated temperature and hydrogen pressure. The process comprises providing in a reaction mixture the polyols, a base, and a metal catalyst prepared by depositing a transition metal salt on an inert support, reducing the metal salt to the metal with hydrogen, and passivating the metal with oxygen, and wherein the catalyst is reduced with hydrogen prior to the reaction. In particular, the process provides for the preparation of glycerol, propylene glycol, and ethylene glycol from sugar alohols such as sorbitol or xylitol. In a preferred process, the metal catalyst comprises ruthenium which is deposited on an alumina, titanic, or carbon support, and the dispersion of the ruthenium on the support increases during the hydrogenolysis reaction.

Inventor: MCCONNELL THEODORE VAN FOSSEN
IPC: G06Q30/00
Filed: 2001-04-06
Abstract: An item velocity monitoring system is provided which interfaces with a consumer retail store that has several cash registers that are tied into a "point of sale" store controller. The item velocity monitoring system is capable of detecting when sales (or other movement activities) of an item are occurring too quickly, or too slowly. The item velocity monitoring system is first "trained" in a learning mode of operations, during which item patterns and group patterns are evaluated and placed into a pattern database. The system then compares the observed item velocity to its model probability velocity, and if the observed item velocity deviates beyond the statistical model, a "velocity event" is generated, declaring one of the above selling "too quick" or "too slow" conditions.

Patent CA-2424572-A1 (CA)
Title: Asynchronous pipeline with latch controllers
Inventor: SINGH MONTEK
IPC: H03K19/00
Filed: 2001-09-21
Abstract: An asynchronous pipeline for high-speed applications uses simple transparent  latches in its datapath and small latch controllers for each pipeline stage.  The stages communicate with each other using request signals and acknowledgment signals. Each transition on the request signal indicates the arrival of a distinct new data item. Each stage comprises a data latch that is normally enabled to allow data to pass through, and a latch controller that enables and disables the data latch. The request signal and the data are inputs to the data latch. Once the stage has latched the data, a done signal  is produced, which is sent to the latch controller, to the previous stage as  an acknowledgment signal, and to the next stage as a request signal. The lat ch controller disables the latch upon receipt of the done signal, and re-enable s the data latch upon receipt of the acknowledgment signal from the next stage . For correct operation, the request signal must arrive at the stage after the  data inputs have stabilized. The asynchronous pipeline may incorporate logic  elements to combine data, as well as matched delay elements for the request,  acknowledgment, and done signals. The asynchronous pipeline may also incorporate clocked CMOS logic gates. Fork and join structures are also provided by the asynchronous pipeline design.

Title: Wind turbine wheel
Inventor: STRAND CARL OLAF
IPC: F03D1/04
Filed: 2003-05-22
Abstract: This invention is a new machine and process to generate electricity from natural wind. The shroud of the wind turbine is circular in shape and can be made any size to suit its application. The front of the shroud faces directly into the wind at all times, thus blocking, catching and funnelling the wind through the turbine wheel. The incoming wind enters the shroud and is immediately funnelled past the internal walls of the shroud which are sloped to the turbine wheel. Since the opening for the turbine wheel is much smaller than the opening of the shroud, the incoming wind is pressurized and accelerated prior to engaging the turbine wheel blades. This powerful captured wind turns the turbine wheel, which turns the drive shaft in the hub of the wheel thus turning the generator which creates the electricity.
