Title: Teaching apparatus and method for visually representing polynomial expressions
Inventor: DREYFOUS RICARDO
IPC: G09B19/02
Filed: 1994-08-31
Abstract: ABSTRACT OF THE DISCLOSURE An apparatus for teaching polynomial expressions includes an arrangement of groups of rows and columns that represent  the  variables  of  factors  of  a  polynomial expression.  Each group of columns or rows has a different width or height, respectively, and represents a different variable  in  the polynomial  expression.   The apparatus enables an algebra student to visualize the rules that apply to polynomial expressions. In one embodiment, the rows and columns are defined by a plurality of pegs or nails fixed to a supporting member.   Each factor of the polynomial  expression  is  represented  by  isolating  the variables of the factors by extending an elastic member around the appropriate pegs.  The intersection of the two isolated factors represents the product of the factors.

Patent CA-2141901-A1 (CA)
Inventor: MOHLER DAVID S
IPC: H04N7/26
Filed: 1995-02-06
Abstract: A signal compression-selection arrangement dynamically trades off signal storage capacity against signal quality, by sacrificing capacity in favor of signal quality whenever capacity is plentiful and sacrificing quality in favor of capacity whenever capacity is scarce. In a messaging system, the arrangement monitors the amount of storage that is presently free and available for storing new messages, either on a system-wide or per-mailbox basis, and automatically selects a higher compression rate than a presently-applied compression rate to be applied to newly-received messages as the amount of free storage falls below each predetermined threshold. Storage capacity may be freed up by recompressing at the new, higher, compression rate those stored messages that were previously compressed at a lower compression rate.

Patent CA-2145529-A1 (CA)
Title: Top circulation line cooling for a modified cook digester
Inventor: RICHARDSEN JAN T
IPC: D21C7/14
Filed: 1993-10-08
Abstract: In the production of cellulose pulp (e.g. kraft pulp) utilizing a continuous digester having a number of different feed points for cooking (e.g. white) liquor and utilizing a high pressure feeder, the volume of cool white liquor that is applied to the feed sys-tem is reduced compared to conventional processing. This can cause excessive hammering, and damage the high pressure feeder and adjacent piping and equipment. In order to avoid this, liquid being recirculated from the top of the digester back to the high pressure feeder is cooled by passing it into a heat exchanger into heat exchange relationship with a cooler liquid, with the flow of coolant automatically controlled by sensing the temperature of the recirculated liquid. The temperature in the feed system can fur-ther be lowered by cooling the cooking liquor, before it is added to the pulp slurry, as by passing it to a flash tank so that its tem-perature is reduced at least 10 °C, and the flashed steam can be used in an evaporator.

Title: Method and apparatus for locating tumors
Inventor: JAIN RAKESH K
IPC: A61B19/00
Filed: 1993-01-15
Abstract: A lesion can be accurately located, its size and its biological potential estimated prior to surgery by measuring the interstitial fluid pressure of the lesion. A pressure-sensing biopsy needle, which is an inner pressure-sensing needle (2) within an outer needle (1), rapidly measures the interstitial fluid pressure of tissue and allows the operator to determine the location and estimate the size of a lesion. The interstitial fluid pressure of the lesion can be correlated with the biological potential and is used to determine whether surgical removal of the lesion is warranted. When surgical removal of the lesion is desired the inner pressure-sensing needle (2) is removed leaving the outer needle in situ, and a hookwire (15) is inserted into the tissue through the accurately placed outer needle (1) thus transfixing the lesion.

Title: Fluid control valve for a hydraulic system operating with variable viscosity, contaminated, fluid
Inventor: MCARTHUR MALCOLM J
IPC: F15B21/045
Filed: 1996-03-18
Abstract: Problems such as slow frequency response and low reliability when operating with contaminated fluids of variable viscosity are alleviated in a low pressure hydraulic system (10) which utilizes a single stage electro-hydraulic, clevis-type pressure control valve (40). The valve (40) includes a control piston (106) referenced to a control pressure within a control pressure cavity (60) to provide a feedback of control pressure which converts the valve (40) from an integral to a proportional control device, thereby enhancing stability of the hydraulic system (10). Compensation for changes in fluid viscosity, as a result of changes in fluid temperature is provided by fabricating a bifurcated portion (98) and/or a metering bridge portion (62) of the valve (10) from materials having dissimilar coefficients of thermal expansion. Exemplary embodiments of a hydraulic system (10) suitable for use in either vehicular or stationary applications involving pressure actuated devices such as a clutch (16) automatic transmissions or anti-lock brakes, are provided.
