Granted: 1992-05-05
Abstract: ABSTRACT          An apparatus to measure the concentration of a constituent of a solution containing dissolved gas includes conduit means connectable to a source of said solution.  Flow control means are provided on the conduit means, selectively to permit the flow of said solution in said conduit means.  Pressure regulation means are also provided on the conduit means to control the pressure of said solution in the conduit means, and maintain the pressure in the conduit means at a level sufficiently high to prevent gassification of dissolved gas in the solution, thereby to prevent foaming in the conduit means.  A gas chromatographic analyser (GCA) is in communication with the conduit means via a sampling valve, to permit the flow of discrete samples of solution into the GCA for analysis.  The interior of the GCA is maintainable at the same pressure as in the conduit means.

Abstract: Abstract of the Disclosure Countershaft Transmission Countershaft transmissions are useful for vehicles such as lift trucks or the like.  But obtaining the desired speed reduction ratios and alignment of the various axes where space is at a premium is difficult.  The subject countershaft transmission provides two forward speeds and two reverse speeds using four compactly grouped rotating clutch assemblies of the interleaved multiple plate and disc type for selectively connecting a plurality of constantly meshing gears in preselected patterns.  A reverse clutch assembly is mounted on a first shaft, a forward clutch assembly and a low speed clutch assembly are mounted on a second shaft, and a high speed clutch assembly is mounted on a third shaft.  A fourth shaft having a bevel pinion gear thereon is located at a minimal drop height "D" from the first shaft to that the longitudinal axis of the bevel pinion gear can intersect the transverse axis of a bevel ring gear associated therewith.  The elements of the disclosed transmission are particularly compact and permit the associated output components on the transverse axis to be located tightly against those longitudinally arranged.

Title: Method and apparatus for making a molasses-based animal feed mass
Inventor: ORWIG RAYMOND L
IPC: A23K10/33
Filed: 1987-10-08
Granted: 1994-11-15
Abstract: A method of, and apparatus for making hard, dense, vitreous molasses-based animal feed supplement masses, the method comprising heating a molasses composition to a temperature within the range of about 240°F to about 285°F to remove all of the water content of the molasses that is necessary to form the desired vitreous masses.  A portion of the heating process may be accompanied by an injection of ambient air into the molasses composition being heated.  Immediately after heating, the molasses composition is cooled, agitated and de-aerated by directing the molasses composition through a cooler and de-aerator including a conduit in which is positioned an offset beater shaft assembly adapted to separate portions of the composition from the remainder thereof while directing cooling air through the conduit about said portions.  After cooling, other animal feed supplements may be mixed with the molasses composition by a utilization of a variable pitch ribbon mixer-auger, further cooled, containerized, and allowed to cure into hard, dense, vitreous masses.
Patent CA-1310703-C (CA)
Title: Method and apparatus for cardioverter/pacer featuring a blanked pacing channel and a rate detect channel with agc
Inventor: MENKEN JOHN
IPC: A61N1/39
Filed: 1987-11-17
Granted: 1992-11-24
Abstract: ABSTRACT      The implantable cardioverter/pacer includes a pacer channel and a rate detect channel both receiving a cardiac signal representative of the ECG of patient.  The pacing channel issues a pacing signal when the amplitude of the cardiac signal fails to exceed a first predetermined threshold within a predetermined time period.  The  rate detect channel has a variable gain amplifier which is controlled by an automatic gain control (AGC).  The AGC increases the gain in the amplifier based upon the level of the cardiac signal applied thereto and upon the time since the last peak of the cardiac signal.  A one shot receives the output of the variable gain amplifier and produces a heart rate signal.  Both the pacing and the heart rate signals are applied to a microprocessor.  The microprocessor ignores or blanks out the first two or three pacing signals in order to allow the automatic gain control in the rate detect channel to increase or approach a maximum in order to determine whether a low level cardiac signal is present which may be indicative of certain ventricular arrhythmias.          After the blanking period, the microprocessor issues appropriate treatments, either pacing or cardioverting, to the heart.

Title: Integrated magnetic resonant power converter
Inventor: ARCHER MICHAEL P
IPC: H02M3/337
Filed: 1988-02-19
Granted: 1992-06-16
Abstract: INTEGRATED MAGNETIC RESONANT POWER CONVERTER          ABSTRACT OF THE DISCLOSURE      A resonant power converter is disclosed which is con-structed on an integrated magnetic core, with primary, secon-dary and tertiary windings  occupying separate  legs of the core.  The tertiary winding is connected in a resonant circuit and induces a flux in the primary leg that causes the primary winding current to assume the shape of a series of generally sinusoidal pulses.   Primary winding switching can thus occur at zero primary current between pulses,  thereby eliminating prior interference problems.   Furthermore, the converter can be operated in a pulse width modulated mode to accommodate for varying output load levels without the problems of low fre-quency  operation  encountered  by  prior  frequency  modulated resonant converters.
