  • Psychrometer for measuring the humidity of a gas flow
    Patent number: 4461167
    Abstract: In a psychrometer for measuring the humidity of a gas flow, especially a gas flow having a temperature of above 100.degree. C., a flow of liquid is supplied to a wick surrounding the wet sensor via a preheater which heats the liquid to approximately the wet bulb temperature of the gas stream before the liquid comes into contact with the wet sensor, thereby avoiding cooling of the wet sensor by the liquid. The necessary preheating of the liquid can be achieved largely by heat exchange between the liquid and the gas flow downstream of the wet sensor; such heat exchange may be effected in part by using an auxiliary wick from which a portion of the liquid evaporates before the rest of the liquid reaches the main wick.

  • Apparatus and method of measuring edgewise compressive deformation
    Patent number: 4458538
    Abstract: An apparatus and method of measuring edgewise compressive deformation in sheet material comprises providing a specimen beam having an inner curved layer of the sheet material to be tested, an outer curved strip spaced radially outwardly of the sheet material, an elastomeric spacer between the sheet and strip, and blocks fixing the opposite ends of the sheet material to the opposite ends of the strip. The spacer is fixed to the backing strip and engaged firmly on the outer radial surface of the sheet material. The ends of the curved specimen beam receive a pure torque which causes compression of the sheet material which can be measured. The sheet material is supported so that it does not buckle with the torque being applied by simple weights connected to rotors which in turn are engaged with the opposite ends of the specimen beam.

  • Rope wick chemical recovery apparatus
    Patent number: 4454680
    Abstract: A new apparatus for the application of liquid chemicals to plants is disclosed. Plants are treated by selectively contacting a wick saturated with chemical solution. As the chemical is deposited on plants, the solution in the wick is replenished by gravitational flow and capillary action from a reservoir at the upper end of the diagonally-positioned wick. Excess chemical not applied to plants is dripped from the lower end of the wick into a collection reservoir from where it can be recovered and recycled for reuse. Adequate mounting and support is provided for all the salient parts to allow for positioning and portability.

  • Powered tree chipper or bark hack
    Patent number: 4452288
    Abstract: An improved power bark hack including a motor of any suitable type which drives one end of an elongated connecting rod mounted in a co-extensive housing which also serves as the tool handle. The cutter is mounted at the free end of the connecting rod which extends out from the handle or housing. Bearing means, such as buttons made of Teflon which are easily replaced in use, are mounted in the end of the housing closely adjacent the end of the connecting rod carrying the cutting tool, whereby the rotary motion imparted by the motor to the drive end of the connecting rod is changed to substantially pure reciprocatory motion at the cutter blade end.

  • Microemulsions from vegetable oil and aqueous alcohol with trialkylamine surfactant as alternative fuel for diesel engines
    Patent number: 4451267
    Abstract: Hybrid fuel microemulsions are prepared from vegetable oil, a C.sub.1 -C.sub.3 alcohol, water, and a surfactant comprising a lower trialkylamine. For enhanced water tolerance by the fuel, the amine is reacted with a long-chain fatty acid for conversion to the corresponding trialkylammonium soap. Optionally, 1-butanol is incorporated into the system as a cosurfactant for the purpose of lowering both the viscosity and the solidification temperature.

  • Method for separating closed bolls of cotton by maturity
    Patent number: 4449391
    Abstract: A method for separating/classifying closed bolls of a given variety of cotton by maturity is disclosed. Harvested, unopened cotton bolls are immersed in a series of solutions having a specific gravity of less than one. The bolls of cotton are thus identified and separated by means of the different specific gravity readings. The specific gravity readings are correlated with the moisture content of the bolls and subsequently the maturity dates of the cotton. Additional steps for cleaning, washing and drying are provided as needed. Alcohol/water solutions are utilized to prepare solutions with specific gravities of 0.8379 to 0.9455.
