Patent CA-1117789-A (CA)

IPC: G01N27/409

Abstract: ABSTRACT OF THE DISCLOSURE         A pair of ceramic chips, formed of similar metal oxide ceramic materials which are semiconductors at elevated temperature, are connected electrically in series and are arranged for exposure to the hot gaseous combustion by-products produced  by an internal combustion engine.  The chips are positioned in the exhaust gas conduit by a ceramic insulator having a plurality of longitudinal passages extending there-through.  A plurality of electrical terminal members are received within the rear of the longitudinal passages. Electrical leads extend from the chips to the terminal members through the plurality of passages and support the chips while providing electrical communication between the chips and the electrical terminals.  The electrical terminals are adapted for communication to electronic and/or electrical utilization means.  One of the pair of chips is processed to exhaust a rapid change in an electrical property responsive to differences in the exhaust gas chemistry and differences in exhaust gas temperature.  The other of the chips is processed to exhibit a rapid change in an electrical property responsive to differences in exhaust gas temperature only.  The preferred material is titania.  For temperatures in the range of from about 700°F to about 1500°F, the application of a reference voltage across the series connected chips will produce a substantially temperature independent voltage variation across either chip in response to changes in exhaust gas chemistry and which is relatively insensitive to changes in the exhaust gas temperature.

Abstract: Abstract of the Disclosure The specification describes a system to indicate the position of the tongues, in a track installation where pivotal tongue switches are interposed between the main track and the tangent track to govern traffic, the system comprising two limit switches positionable on opposite sides of each tongue and having actuators separated by the included angle of tongue movement between the home positions of each tongue, each limit switch at one tongue being paired to a limit switch at the other tongue corresponding to a home position, the limit switches thus paired each having two pairs of normally closed contacts arranged in parallel to one another which open only when the tongues are in home position, the two pairs of parallel contacts of one limit switch being joined in series to the two pairs of parallel contacts of the other limit switch and the respective pairs being series-connected to a time delay relay which thereby starts to time out as the tongues are in transit, and the time delay relay having normally open contacts series-connected to an indicator which is energized by closure of the time delay relay contacts if the tongues are too long in transit.

Abstract: METHOD FOR PLACING BALL SEALERS ONTO CASING PERFORATIONS            ABSTRACT OF THE DISCLOSURE           A method is disclosed for transporting ball sealers down a perforated casing of a well to affect fluid diversion when hydraulically treating a formation penetrated by the well.  In this invention, ball sealers are transported to said perforations in a carrier fluid system comprising a leading fluid portion having a density greater than said ball sealers and a trailing fluid portion having a density less than said ball sealers.  The ball sealers will be moved downwardly in the casing to the perforations and will seat onto the perforations through which fluids are flowing to divert fluid through the unplugged perforations.

Abstract: GRAPHIC  DISPLAY  ILLUMINATOR          Abstract of the Disclosure:        In the display of transparent graphics it is necessary to provide a base structure which will give support to the graphic medium and the light source with which it is illuminated.        In this invention the base structure is constructed as a single rigid frame, fitted with an illuminant and providing one or more openings in which individual graphics are inserted in parallel opposing recessions. The distance between the recessions is less than the corresponding dimension of the display; support for the graphic is provided by the resilience inherent in certain sheet plastic materials with which the graphic is in contact. The flexible graphic and plastic sheet or sheets are compressed to form a convex or concave curve, and inserted in the recessions. The display, having a tendency to return to its original flat configuration, applies pressure to the base of the opposing recess-ions, and maintains the display within the base structure without fasteners or adhesives.        The basic display may be embellished with bases, lids, baffles, suspension devices or other preferred attachments, but requires   nothing but the items detailed to make it functional.

The drive belt assembly includes an unitarily formed, continuous or endless, flexible drive belt having an inner side and an outer ground engaging side.  The unitary drive belt assembly includes a central endless section and a pair of laterally spaced endless side sections.          A plurality of longitudinally spaced members unitarily interconnect the side sections to the central belt section.  A plurality of unitary drive lugs project inwardly from the inner side of each of the belt sections and selected lugs are located proximate to the unitary interconnecting members.  A pluraliry of rigid members are connected to the drive belt.  Each rigid member has a first section that is fixed to the one interconnecting member and a second or offset section which is in supporting and cooperative relation-ship with each of the selected lug members.  The lug members and rigid metal members cooperate to guide the movement of the drive belt relative to the slide rail suspension system, commonly used on snowmobiles.

Abstract: ABSTRACT OF THE DISCLOSURE        A process for the continuous production of a butter-like edible fat product, spreadable at refrigerator temperature and consisting of cow's cream and 15 - 30% (based on the total content) of a vegetable, tocopherol-containing triglyceride oil, comprises the following steps.  First, the fat content of the cream is adjusted to 36-38% by weight, whereupon the cream is cooled to 3-4°C and stored for at least 3 hours. Then the cream is pumped in a stream to a continuous butter making machine of the Fritz type.  All or a considerable portion of the oil is injected into the stream of cream between the storage and the butter making machine.  After the admixture, but ahead of the butter making machine, the injected oil is finely divided and emulsified.  The relative amounts of the cream and the injected oil in the stream entering the butter making machine is so adjusted to obtain a total fat content of more than 40% by weight.  The temperatures are controlled so that the mixture entering the butter making machine will be at 5-6°C.  Churning is effected at a temperature of 5-7°C.  Unless all oil has been injected into the stream, the remaining portion of the product's oil is added to the working section of the butter making machine.

Abstract: VEHICLE LEVELING DEVICE                       ABSTRACT OF THE DISCLOSURE         A leveling device is attached to a vehicle to assist in main-taining a body assembly at its preferred height even when added weight is installed in the body assembly  of the vehicle.  The leveling device includes a housing which is connected to either the body assembly or a wheel mounting assembly and a piston which is movably supported in the housing extends therefrom to connect with the other of the body assembly and the wheel mounting assembly.  The piston cooperates with the housing to substantially define a pair of chambers and a passageway within the piston connects the chambers with each other.  A pressure source, such as a vacuum or low pressure air pump, is in communication with the passage-way and a first valve normally closes communication between the pair of chambers and the pressure source.  A control member carries a second valve and cooperates with the first valve, when the body assem-bly is moved toward the wheel mounting assembly beyond a normal travel distance, in order to open one of the chambers to the pressure source.          As a result a pressure differential  is established across the piston so as to oppose movement of the body assembly toward the wheel mounting assembly.  The control member is actuated automatically when the body assembly is moved toward the  wheel mounting assembly to a position defining a minimum distance between the two assemblies.
