Patent CA-2135305-A1 (CA)
Title: Apparatus and method for removing compounds from a solution
Inventor: SMITH CLARK R
IPC: B01D61/02
Filed: 1993-05-04
Abstract: Method and apparatus for the treatment of fluids, particularly wine, to remove unwanted substances. The wine is first treated in a reverse osmosis treatment unit, generating a retentate and a raw permeate. The membrane for the reverse osmosis unit is selected to pass in the permeate the unwanted substances, which in the case of wine may be volatile acidity (ethyl acetate and acetic acid). The raw permeate is then subjected to a treatment: column. In the case of volatile acidity, this is an anion exchange column, which removes the acetic acid from the permeate by anion exchange and removes the ethyl acetate by base hydrolysis. This produces a purified permeate, which is depleted in volatile acidity (which is passed through with the raw permeate), but contains other components desirable for the wine. The purified permeate is then recombined with the retentate from the reverse osmosis column, and the result is wine with the volatile acidity and little else removed. This wine may be recirculated through the system to remove yet more of the volatile acidity. The method may also be applied to the removal of acetaldehyde, in which case a distillation column is used instead of the anion exchange column, and the distillation residue constitutes the purified permeate which is recombined with the retentate from the reverse osmosis column. An embodiment utilizing a high-energy distillation column may be used to separate out alcohol and water, and then add either the alcohol or the water back to the reverse osmosis retentate, thus producing either a higher alcohol or a lower alcohol beverage, respectively.

Patent CA-2142797-A1 (CA)
Inventor: CANTRELL THOMAS G
IPC: G06F12/00
Filed: 1995-02-17
Abstract: A cache manager efficiently supporting both connected and disconnected client operation. A single integrated cache is maintained for file system data, status and pathname information. File system requests are satisfied by the cache if possible and passed to a remote file system for servicing if necessary. The cache manager is independent of operating system file syntax and distributed file system protocol.      Disconnected operation is supported through an aggressive caching policy and by logging of file system modifications. Modification logs are created when the client is disconnected by logging objects that optimize the log as it is created. Cache file system objects can have multiple parents each with different naming syntax because the object name is not cached.

Title: Automatic addressing of information bus devices
Inventor: SAVAGE THOMAS W
IPC: G06F13/14
Filed: 1995-05-19
Abstract: An automatic addressing technique for flexibly specifying the individual physical addresses of a plurality of devices coupled to an information bus.  An anchor pattern is applied to an address bus of a plurality of address taps sufficient to uniquely specify the numbered J of devices to be attached thereto.  Each device is connected to a tap on the address bus, each tap having the same number of bits.  A plurality of address transform elements are serially connected to the bus, each transform element being located between adjacent tap positions.  Each transform element converts the address pattern coupled to its input to another pattern capable of uniquely specifying the next address in the desired sequence. A wide variety of address sequences are available for selection, with each particular address sequence automatically determined by the related specific anchor pattern.  The transform elements are passive elements, and no jumpers or settable switches are required to specify the physical addresses when configuring or reconfiguring the system.

Title: Method of and apparatus for measuring ice distribution profiles
Inventor: GERARDI JOSEPH J
IPC: G08B19/02
Filed: 1994-03-08
Abstract: The present invention is an improved ice sensor which is particularly effective in measuring and quantifying non-uniform, heterogeneous ice typically found on aircraft leading edges and top wing surfaces. In one embodiment, the ice sensor comprises a plurality of surface mounted capacitive sensors (221, 223, 225) eachhaving a different electrode spacing. These sensors measure ice thickness by measuring the changes in capacitance of the flush electrode elements (210, 212, 214, 216, 218, 220) due to the presence of ice or water. Electronic guarding techniques are employed to minimize baseline and parasitic capacitances so as to decrease the noise level and thus increase the signal to noise ratio. Importantly, the use of guard electrodes (230) for selective capacitive sensors also enables distributed capacitive measurements to be made over large or complex areas,  independent of temperatureor location, due to the capability of manipulating the electric field lines associated with the capacitive sensors.
