Patent CA-1082085-A (CA)
Inventor: HARRIS JAMES T
IPC: B60C17/10

Granted: 1980-07-22
Abstract: ABSTRACT OF THE DISCLOSURE         An enclosed container having a divided chamber with an air pressure section and a liquid coolant section separated by a pressure-transmitting wall.  A one-way inflation valve in the container is in communication with the air pressure section for inflation of this section. A liquid release valve in the container is in communica-tion with the liquid coolant section and is set to release liquid into a tire cavity when the tire is operated in a deflated condition.  The container is of a resilient, noncollapsible material for retaining air under pressure and for gripping the rim  on which the tire is mounted.          The  method of dispensing liquid coolant includes pouring the coolant into the liquid section, inflating the air pressure section to bleed air out of the liquid section,  mounting the container on the rim with the inflation valve and release valve in communication with the tire cavity, inflating the tire to normal tire  mount-ing pressure to provide liquid ejecting pressure in the air pressure section of the container, reducing the air pressure in the tire cavity to normal tire operating pressure, and releasing the liquid coolant from the liquid section upon opening of the release valve in response to reduction of the air pressure in the tire cavity to an amount below the normal operating pressure as in the event of a puncture or blowout for cooling and lubrication of the tire.

Abstract: ABSTRACT OF THE DISCLOSURE           An apparatus for inductively heating cooking utensils comprising four induction cooking coils excited by a central power oscillator providing an alternating sinusoidal excitation voltage at about 25 kilohertz which is 100% amplitude modulated at 120 hertz.    Power to the four induction coils is duty cycle controlled by four 60 hertz triacs each series inserted between the power oscillator and a respective one of the induction coils.  The triacs switch to excite their respective induction coils only at the zero point of the excitation voltage modulation envelope.  Line power fluctuations are minimized by sequential switching of the triacs in a manner that results in an effective power switching frequency of approximately 46 hertz when all four induction cooking coils are excited.  The central power oscillator is inherently protected from high ? load conditions without the provision of feedback loops.

Abstract: ABSTRACT OF THE DISCLOSURE            The invention is directed to an axially alignable nuclear fuel pellet of the type stacked in end-to-end relationship within a tubular cladding.  Experience has shown that fuel cladding failures can occur at pellet inter-face locations due to mechanical interaction between misaligned fuel pellets and the cladding.  Mechanical interaction between the cladding and the fuel pellets loads the cladding and causes increased cladding stresses.  Nuclear fuel pellets constructed according to the invention are provided with an end structure that increases plastic deformation of the pellets at the interface between pellets so that lower align-ment forces are required to straighten axially misaligned pellets.  Plastic deformation of the pellet ends results in less interaction between the cladding and the fuel pellets and significantly lowers cladding stresses.  The geometry of pellets constructed according to the invention also reduces alignment forces required to straighten fuel pellets that are tilted within the cladding.  Plastic deformation of the pellets at the pellet interfaces in both axial and transverse direc-tions is increased by providing pellets with at least one end face having a centrally-disposed raised area of generally convex shape so that the mean temperature and shear stress of the contact area is much higher than that of prior art pellets.  Fuel pellets constructed according to the inven-tion may be provided with one end having a centrally-disposed raised area and the opposite end flat or the opposite end may also be provided with a centrally-disposed raised area, or the opposite end may be provided with a centrally-disposed depression having a depth less than the height of the raised area of an adjacent pellet.

Abstract: PROFILE SENSING DEVICE AND METHOD         FOR BODIES            (Abstract of the Disclosure) Apparatus and method particularly adapted for detecting the profile deflection condition in a wheel struc-ture of the type comprised of a pneumatic tire mounted on a wheel rim and which deflection may be caused by tire under inflation or overloading.  A sensing and actuating structure constructed from flexible material having high flex fatigue characteristics to include a body portion and a profile sensor is conveniently mounted to the drop center portion of the rim such that the profile sensor extends into the tire cavity.  The dimensioning of the profile sensor is such that it is positively engaged by the inside of the tire wall when tire profile deflection reaches an amount greater than a predetermined maximum amount due to overloading or under inflation, to thereby cause flexure in the profile sensor generally inwardly toward the rim.  This flexure causes a flexure reaction in the sensing and actuating structure body portion also generally inwardly toward the rim and the body portion houses a small radio transmitter and a piezoelectric device or generator.  The piezoelectric device is configured and disposed such that the flexure reaction of the body portion in response to flexure of the profile sensor causes an electrical discharge therefrom.  This electrical discharge is electrically interconnected to the radio transmitter for selectively causing energization thereof.  The radio signal thus selectively transmitted is received by a receiving unit spaced remote from the wheel to cause energization of con-venient indicating means located within the vehicle itself for showing that tire deflection greater than a predetermined maximum amount has been detected.

Abstract: ABSTRACT OF THE DISCLOSURE      A method and reagent for reducing errors in any assay systems wherein nicotinamide adenine dinucleotide (NAD) is reduced, the reduced form of NAD being a quanti-tative measure of the sample constituent being measured, and being subject to reaction with any pyruvate and lactic dehydrogenase (LDH) which may be present.  Specifically, the method comprises conducting the assay in the presence of oxalic or oxamic acids or their salts, which form an inactive complex with LDH, thereby eliminating interferences due to the presence of any LDH.  Glucose and creatine phosphokinase assays are examples of essays wherein the reduced form of NAD is measured, and consequently, the presence of either pyruvate or lactate in the sample will cause errors in the assay.  The method can also be employed in assay systems wherein the reduced form of NAD (NADH) is oxidized to NAD.  In such systems, the disappearance of NADH is a measure of the constituent being measured so that any interference can cause errors in the assay.  An example of such a system is the measurement of plasma ammonia using glutamic dehydrogenase.

Abstract: ABSTRACT OF THE DISCLOSURE       An apparatus and method for deriving an oxygen associa-tion curve for a blood sample wherein the sample is placed on a transparent support and is covered by a gas-permeable membrane element.  The support is mounted in a gas treatment chamber with transparent windows on opposite sides of the support to provide an optical path through the support normal to the sample. Radiant energy is directed along this optical path, said radiant energy including two light frequencies, one having a wavelength at which there is substantially no change in absorbance as bet-ween oxygenated and deoxygenated blood and the other having a wavelength at which there is a relatively large change in absorbance as between oxygenated and deoxygenated blood.  A controlled source of deoxygenating gas, such as nitrogen, and a controlled source of oxygen are connected to the chamber. An oxygen electrode is mounted in the chamber and generates the X component, corresponding to oxygen in the chamber, in an X-Y recorder.  The difference in absorption of the two frequencies is measured and from this is derived a signal forming the Y component in the X-Y recorder, which thus provides a curve corresponding to the light absorbance changes in the sample while it is being oxygenated.
