Patent CA-1069178-A (CA)
Inventor: SUTPHIN ELDON M JR
IPC: G01M15/04

Granted: 1980-01-01
Abstract: Abstract The relative compression in the cylinders or an internal combustion engine is tested by analyzing the starter motor current waveform when the engine is cranked with the ignition or the fuel inhibited.  In asymmetrical engines, where the compression strokes of individual cylinders are unequally spaced in time, the starter current waveform may contain double-hump cycles.  The area under each double-hump cycle is integrated, and the integration peaks are compared. The compression in one or more cylinders is deficient if the minimum integration peak is less than the maximum integration peak by a significant percentage such as 15 per cent or more.

Abstract: ABSTRACT    A continuous solvent extraction process for tar-sand uses a closed rotary contactor.  A tar-sand/water slurry stream and a solvent stream are passed countercurrent through the contactor and three phases are formed:  tar-sand solids at the bottom of the contactor, a barrier layer of water in which the solids are contained and an uppermost solvent phase.  The solids during their travel through the contactor are repeatedly lifted off the bottom of the contactor and tumbled through the solvent phase so that the bitumen oils content of the tar-sand is progressively dissolved in the solvent.  A solvent stream containing the dissolved bitumen oils is removed from one end of the contactor and discard stream con-sisting essentially of sand and water is removed from the other end.

Abstract: ISOLATION CIRCUIT WITH    DUTY CYCLE FEEDBACK        ABSTRACT OF THE DISCLOSURE    An isolation circuit with duty cycle feedback is disclosed which includes an operational amplifier with capacitive coupled negative feedback such that its output voltage varies to maintain its input terminals at the same potential, and which output is connected to the control terminal of a voltage controlled oscillator which generates a square wave voltage in which the ratio of ON time to the total period is directly related to the voltage from the operational amplifier.  The output pulses of the voltage controlled oscillator are fed through a resistor to the negative input terminal of the operational amplifier.  The output pulses from the oscillator are also fed through a driver transistor to control the input of an opto-coupler.  The output from the opto-coupler passes through an amplifier to produce a square wave voltage with the same ON time ratio as the voltage controlled oscillator.          The average value of this square wave voltage is obtained by a low pass filter and is directly proportional to the input analog voltage.

Abstract: ABSTRACT OF THE DISCLOSURE            Improved systems, apparatus and methods for measuring downhole parameters in a well being drilled in the earth with apparatus comprising a drill string, a mud pump for circulating drilling fluid, and flow restriction means located near the bottom of the string so as to cause a pressure drop between the restriction means and the borehole annulus that surrounds the drill string.  In accordance with one aspect of the invention, the improvements involve down-hole pulser means for generating negative mud pressure pulses which are utilized to transmit information concerning downhole parameters to above ground equipment.  The improved downhole pulser means utilizes valve means to bypass the restriction means in a manner that results in the efficient generation of effective pulses with minimum expenditure of electric energy.  In accordance with another aspect of the invention, improved structure is provided for housing the pulser means and for accommodating associated downhole apparatus.  In accordance with another aspect of the in-vention, improved methods are provided for extracting nega-tive mud pressure pulse signals from interfering signals resulting from mud pressure variations due to the mud pump means.  In accordance with a further aspect of the invention, improved direct current downhole power supplies are provided.

Abstract: ABSTRACT OF THE DISCLOSURE           A process is provided herein for preventing corrosion caused by the formation of iron pentacarbonyls and sulfur-con-taining iron carbonyls, of apparatus made of iron or normal steel and occuring during the treatment of a gaseous mixture containing carbon monoxide and hydrogen sulfide with an aqueous alcoholic solution acting as a physical absorbent.  The process involves conducting the treatment in the presence of at least one alkaline reacting inorganic compound selected from the group consisting of ammonia and sodium hydroxide.  This substantially prevents the formation of the iron pentacarbonyls and carbonyls.  It is therefore possible to replace the heretofore employed apparatus parts made of high alloy fine steel by those made of normal steel and thereby to attain considerable savings in initial investment cost without thereby impairing the flawless operation of the process.

Abstract: A B S T R A C T      An improved spring assembly and coil spring therefor is provided, for a mattress or the like.  The spring assembly includes a plurality of spiral coil springs, arranged in substantially parallel rows, a plurality of cross helicals lacing together adjacent springs in the same row, and at least a pair of adjacent coil springs, with laced-together terminal convolutions, that are restricted in their movement relative each other to a maximum angle of deflection.  Such pairs of coil springs have a hinging action, relative one another, about the adjacent offset portions of their terminal convolutions, until the maximum deflection angle between the offsets is reached. Further loading of one spring after this angle is reached results in compression of adjacent springs and greater resistance to loading for a given degree of spring compression, i.e. greater firmness.

Title: Low pressure and run-flat warning system  for a pneumatic tire
Inventor: SARKISSIAN BERGE
IPC: B60C23/06
Filed: 1979-08-31
Granted: 1981-12-29
Abstract: ABSTRACT     A pneumatic run-flat insert for a pneumatic tire is provided with circumferential sections having different radii. During vehicle operation in a run-flat condition the different insert radii cause a vibratory disturbance at a wheel axle that alerts the driver of the existence of a run-flat condition or an abnormally low-pressure condition in the tire. During normal driving conditions there is clearance between the insert and the tire liner and no warning vibrations will occur in the wheel axle.     In various embodiments of the invention the different insert radii correspond to two or more ply sections in an insert ply having different cord angles. A relatively high cord angle ply section will furnish a relatively larger radius than the ply section with a rela-tively low cord angle.      In further embodiments of the invention a pneumatic or non-pneumatic run-flat insert includes one or more bumps on the insert crown formed of rubber strips for example that furnish the insert with an out-of-round condition that causes a similar vibrating disturbance to warn the driver of a low-tire pressure or run-flat condition.
