Patent CA-2071123-C (CA)
Inventor: AGRAWAL RAKESH
IPC: F25J3/06
Filed: 1992-06-12
Granted: 1996-12-03
Abstract: A process and system for controlling a cryogenic air separation unit during rapid changes in production.  During operation of an air separation unit, demands for oxygen will vary and the pressure of the feed air will fluctuate.  The changes in oxygen demand and feed air pressure translate into a ramping, either up or down, of the distillation system pressure in the air separation unit.  Because the product streams have tight purity requirements, the ramping system pressure (which could adversely affect product purity) is compensated for.  This compensation is by way of a net transfer of refrigeration, in the form of liquid nitrogen, into and out of the distillation system.  This transfer of refrigeration is implemented using a storage vessel of liquid nitrogen connected to the reflux path of the distillation system.  Liquid nitrogen via the reflux path is removed and stored or added to the distillation system to decrease or increase the refrigeration, respectively.

Title: Window for a device with elevated inner chamber temperature
Inventor: BORENS MANFRED
IPC: F24C15/04
Filed: 1993-03-15
Granted: 1999-09-14
Abstract: In a window for ovens, in particular household baking ovens, with a window structure that consists of several panes, at least one of the panes is angled in comparison to the other panes. Because of this a lower outer surface temperature results on the outer pane of the multiple pane arrangement turned away from the oven inner chamber with elevated temperature. The frame of the multiple pane arrangement can also have openings on the top and bottom in the area between the outside pane and the center pane. In combination with this measure, which permits convection of the outside air through the outer pane intermediate space, an additional reduction of the temperature of the outer pane can be achieved. This air convection can be increased by the fact that the angled center pane converges toward the outer pane at the top.

Granted: 2004-04-13
Abstract: An absorbent article is disclosed which exhibits enhanced wicking capability. The absorbent article includes a liquid-permeable cover, a liquid-impermeable baffle and an absorbent enclosed therebetween. The absorbent is constructed of first, second and third members. Each member has a wicking capability for body fluids discharged by a human body. The first member has a high wicking capability, the second member has a lower wicking capability than the first member, and the third member has a higher wicking capability than the second member. The different wicking capabilities of the three members promotes a systematic distribution of body fluid away from the body-side cover down into the absorbent article. The second member also has an equal or greater width than either the first or third members so as to provide a visual cue of when the absorbent article is in need of changing. By changing the absorbent article when the second member appears to be soiled, the user can prevent side leakage and soiling of an adjacent undergarment.

Title: Method and apparatus for estimating signal weighting parameters in a receiver
Inventor: CHIASSON GREGORY M
IPC: H03M13/00
Filed: 1993-02-08
Granted: 1998-06-30
Abstract: A receiver (100) has improved signal weighting parameter estimation. The receiver receives a signal (101) having encoded data. A decision circuit (106) is coupled to the received encoded data to generate a first signal weighting parameter which is used to modify the received encoded data. The modified data is then decoded to output the decoded data. The decoded data output is then re-encoded using a technique similar to that used by the transmitter. The re-encoded data is then used to calculate a second signal weighting parameter which, in turn, is used to modify a stored replica of signal (101). The modified version of the stored replica is then decoded to yield a more accurate estimate of the information contained within the signal (101) at a receiver (100).

Title: Detection of location of faults in cables
Inventor: MASHIKIAN MATTHEW S
IPC: G01R31/11
Filed: 1993-02-19
Granted: 1998-06-23
Abstract: A method and apparatus for locating an incipient fault at a point along the length of an insulated power line includes the application of the excitation voltage at an open end of the power line.  The signal pulse transmitted along the power line to the open end is passed through a high pass filter.  The filtered signal is amplified and passed through a band pass filter to remove a high frequency portion of the signal containing a large proportion of noise relative to the frequency of the partial discharge frequency from the incipient fault.  This filtered signal is passed to a digital storage device which also receives the amplified signal directly from the amplifier and stores digital data.  The stored digital data is processed to identify the peaks reflecting the point of partial discharge in the power line.

Title: Control of Male Fertility Using Externally Inducible Promoter Sequences
Inventor: ALBERTSEN MARC C
IPC: A01H5/00
Filed: 1993-03-09
Granted: 1996-09-10
Abstract: An inducible promoter is used to regulate expression of a gene which is known to be critical to male fertility. The selected gene's control sequences are modified so that it is normally "off" and as a result the plants are male sterile. When it is desired to reproduce the male sterile plants, male fertility is restored by treating the plants with a non-phytotoxic chemical which induces expression of the critical gene. A critical gene is one which affects flavonol production and in particular compounds of the formula:    <IMAGE>   wherein R1, R2, R3, R4, R5, R7, and R8, are hydrogen, hydroxyl or alkoxy having from 1 to 4 carbon atoms. Particularly preferred flavonols include galangin, kaempferol, iso-rhamnetin, quercetin and morin.
