Patent CA-1118327-A (CA)

Abstract: ABSTRACT OF THE DISCLOSURE      There is disclosed a method and apparatus for analyzing whole blood samples which feature impregnating a gel medium used for the analysis of the whole blood sample with an inert substance.  When the whole blood sample is placed on the gel medium, the inert substance diffuses from the gel as the plasma solutes of the blood diffuse into the gel.  The amount of the inert substance diffusing from the gel medium is inversely proportional to the hematocrit of the blood sample.  In one embodiment, plasma solutes are caused to react with one or more reagents in the gel medium to assay various specific analytes. Also, the hematocrit, indicated by the diffusion rate of the inert substance from the gel, is determined and used to correct such assay.            Docket 2121 A

Abstract: PRECISION MATERIAL FILLING SYSTEMS              ABSTRACT The filling systems according to the invention uti-lize pneumatic pressure maintained within closely held tol-erance limits to impose a constant dispensing force upon the material being dispensed.  The invention in one embodi-ment utilizes a buffer tank system in which the product to be dispensed is transferred from a supply tank (11) to the buffer tank (12) where the desired pressure is induced through a pneumatic head which is introduced above the pro-duct level.  The product level in the buffer tank (12) is allowed to fluctuate within a relatively narrow band of depth so as to negate the effect of changes in gravity head pressure.  The closed and pressurized system is refilled by forcing the incoming product into the tank (12) under a higher pressure than that in the buffer tank (12). The air within the tank (12) that is displaced as a result of intro-ducing the new product is automatically vented to atmosphere through a precision regulation system (45).        The pressure balancing system incorporates either a piston or diaphram balancing member controller device (81) which controls a three-way pneumatic valve (72) for charging or venting the dispensing tank (58).  The desired product set point pressure is applied to one side of the balancing mem-ber (80) and the actual product pressure is applied to the other side.  As the level in the tank (58) drops, the grav-ity head pressure drops, and this is sensed at the bottom of the tank.  The balancing member (80) favors the side with the lower pressure causing the three-way valve (72) to open and pneumatically charge the tank (58) until the set point pressure and the actual product pressure are equal.  If the actual product pressure becomes greater than the set point pressure, the balancing member (80) actuates the three-way valve (72) to exhaust the excess pressure to atmosphere. The response time and sensitivity of the system are adjusted by a flow control valve (68) in the charging circuit, and by increasing or decreasing the pressure differential between the charging pressure and the set point pressure.

Abstract: CLOSURES               Abstract of the Disclosure A container closure especially for large containers and having circumferentially spaced tool access regions in a rim flange for insertion of a removal tool.  These access regions are located between a base of the flange and a locking bead.  Between the access regions, sections of a discontinuous locking bead extend around the inside of the flange, the bead being discontinuous across the circumferential area occupied by the access regions to enable a removal tool to be inserted downwardly through the access regions and between bead sections.  Rim stiffening pro-trusions project from the outer surface of the flange beneath the access regions and across the circumferential line of the locking bead to stiffen the flange to prevent it from splitting when a removal tool is inserted down through the access regions and between bead sections.  Any force applied by the tool to flex the flange outwards is carried circumferentially around the flange to cause flange flexure at the bead sections and assist in unlocking the bead.

Abstract: Abstract of Invention A process for making styrene by the cracking of beta-phenethyl acetate wherein the beta-phenethyl acetate is derived from the esterification of beta-phenethyl alcohol.  The latter is derived from the homologation of benzyl alcohol-benzyl acetate mixtures. The esterfication of the beta-phenethyl alcohol may be partial because it has been found that up to 20% by weight of beta-phenethyl alcohol may be fed to the cracking step and also converted to styrene.  Benzyl alcohol and benzyl acetate can also be fed to the cracking step because it has been found that they are essentially inert at cracking conditions.

Abstract: ABSTRACT             METHOD AND MEANS OF PRESETTING THE OUTPUT RATE OF A CENTRIFUGAL PUMP AGRICULTURAL METERING SYSTEM          A system and method for metering the appli-cation of liquid agricultural chemicals to the soil from a moving vehicle at a substantially constant preselected application rate, e.g. gallons per acre, substantially independent of vehicle speed.  The system uses a centrifugal pump driven at a rate sub-stantially linearly proportional to vehicle speed and having its outlet pressure substantially propor-tional to the square of its speed.  The pump receives liquid from a supply tank and delivers it to liquid discharge orifice means the rate of flow through which is substantially proportional to the square root of the pressure thereon.  The system also in-cludes a line having adjustable orifice means therein controllable by the vehicle driver while the vehicle is moving for returning a portion of pump delivery liquid to the tank and controlling upstream pres-sure.  Orifice pressure Pn required to achieve a pre-selected application rate at a selected vehicle speed can be determined readily.  For each such Pn there is a corresponding calculable, or ascertainable by test, pump system pressure Pc when flow to the discharge orifice means is shut off.  A Pc pressure gauge is readable by the driver and also preferably a Pn gauge.  Pn is first determined and then the corres-ponding Pc.  The vehicle is moved at the selected speed with the pump being driven and flow to the discharge orifice means shut off while the driver adjusts the adjustable orifice means to preset the Pc corresponding to the determined Pn.  Flow to the discharge orifice means can then be started to ob-tain substantially the preselected application rate at substantially all vehicle speeds.

Abstract: ABSTRACT A data transmission system is disclosed in which a transmitter always transmits a carrier to a receiver and modulates the carrier by means of data to be sent.  The receiver has a demodulator for recovering the data sent during a communication period.  The transmitter includes a sending code convertor which inverts specified bits of the data being sent in the data sending period of the total communication period.  The receiver includes a detector which detects whether the data demodulated during the communication period has been subjected to bit inversion or not and so can discriminate be-tween the data sending period and the "pause" period which is the period within the communication period during which no data is actually being sent. The receiver also has a code converter which decodes the demodulated data received.

Abstract: 22                  48,379 ABSTRACT OF THE DISCLOSURE         This concerns a compensator for electrical lines fed by a turbine-generator.  The mechanical properties of the  turbine-generator  are  such  that modulation of  the terminal voltage is possible due to subsynchronous mechan-ical torsional oscillations.  If the carrier frequency or synchronous frequency of the generator minus the torsional oscillation frequency is equal to the resonant frequency of the electrical line driven thereby, a relatively large side band current may flow in the electrical line at the resonant frequency.  The effect of this current may feed-back through the air gap of the generator to increase the torsional oscillation.   A boot strapping effect between the electrical properties of the line and the torsional oscillation may thus result which could ultimately end in shaft breakage.  The present apparatus utilizes the tor-sional oscillation signal to modulate compensating induct-ance connected in parallel between the lines of the elec-trical  system to  thus generate a small current at the appropriate electrical resonance frequency.  This current leads to the production of a compensating line current at that frequency which in turn opposes the previously des-cribed undesirable effect.
