Granted: 1984-02-14
Abstract: APPARATUS FOR ANALYSIS OF COMBUSTIBLE SUBSTANCES Abstract of the Invention A method and apparatus for the analysis of substances by providing a metallic oxide sensor as a detector in combination with a gas chromatograph employing a carrier gas.  The mixture of the carrier gas with the gas or gases to be analyzed is passed through a separation column and into a chamber where the constituents thereof impinge on the surface of the sensor. When a combustible compound, such as carbon monoxide, is present in the carrier gas, the metallic oxide is reduced causing a change in resistance which is a function of the concentration of the carbon monoxide in the carrier gas.  Combining the metallic oxide combustible gas sensor with a simple gas chromatographic apparatus makes it possible to identify the combustible gas on the basis of its retention time in the separation column.  The magnitude of the response is used as a measure of the combustible gas concentration.

Abstract: ABSTRACT OF THE DISCLOSURE           A viscous fan clutch (10) is typically employed in a fan drive mechanism within a truck or automobile.  A shaft (12) driven by the engine, rotates a clutch member (24) within the fan drive.  The clutch member is arranged for fluid engagement with a cover assembly (38) for the transmission of torque thereto when the fluid is disposed in an operating chamber (70) defined by complementary shear surfaces (30, 31, 56, and 57) in the clutch and cover.  During relative rotation between the clutch and cover, fluid is pumped from the operating chamber to primary (76) and secondary (77) fluid storage chambers.  Independent fluid temperature responsive control valves (120 and 190) provide for selective communication between the storage chambers and the operating chamber to effect modulation of the total fluid flow whereby dual speed operation of the clutch is achieved.  In the preferred embodiment, one of the valves operates in response to impinging ambient air at a relatively low temperature and the other valve operates in response to sensed engine coolant temperature at a relatively high temperature.

Abstract: TREATMENT OF INDUSTRIAL WASTEWATERS                 Abstract of the Disclosure An industrial wastewater treatment method is described whereby heavy metals dissolved in the wastewater are precipitated as a slurry which, when allowed to settle, will form a sludge containing at least 10 weight percent solids.  In the method, an aqueous suspension or solution of a neutralizing agent is introduced into a first reactor.  A suspension containing particles of carrier agent is also introduced into the first reactor.  A portion, if not all, of the neutralizing agent is adsorbed on the surface of the particles of the carrier, which are maintained in suspension in the first reactor.  The carrier, with its adsorbed neutralizing agent, is passed to a second reactor and simultaneously the contaminated industrial wastewater is added to the second reactor.  The pH of the wastewater is adjusted to a range between 8.4 and 10.6 by the neutralizing agent.  Within such pH range, a substantial portion, if not all, of the heavy metals are precipitated in the form of a slurry.  The mixture in the second reactor is passed to a solids separation device.  The solids in the slurry settle to the bottom of the device to form a sludge which is removed therefrom.  Purified water is removed as an overflow from the separation device.  Optionally, a flocculant may be added to aid in settling the solids.     Insoluble calcium salts may also be precipitated in the second reactor.  Such insoluble salts are adsorbed on the surface of the carrier and/or the heavy metal slurry par-ticles and become part of the sludge formed in the separation device.

Abstract: VORTEX FLOWMETER BLUFF BODY              ABSTRACT OF THE DISCLOSURE         A vortex flowmeter       utilizes a bluff body or bar      which creates vortices that are sufficiently stable and of sufficient strength to provide for pressure signals that are easily sensed, and at the same time achieves satisfactory linearity between the frequency of the vortices and the rate of flow past the sensor.  The flowmeter      is designed so that the same sensor arrangement      for sensing the frequency of vortex generation can be used for flowmeters designed for a wide range of pipe or line sizes.  By utilizing the cross section geometry of the bluff body or bar      disclosed herein, the section of the body that is used for mounting the sensor      is the same width, which is the critical dimension for sensor mounting, for line sizes from two inches (5.08 cm) to eight inches (20.32 cm) inclusive and line sizes from one inch (2.54 cm) to one and one-half inches (3.81 cm) inclusive.  The ability to have a standard sensor for a number of different meter sizes reduces inventories and manufacturing costs, and also makes service of sensors easier.  The flowmeter      of the present invention not only permits the interchangeability of sensors      across a wide range of pipe sizes, but also has good linearity, is easy to manufacture, and continues to operate reliably after extensive usage.
