Abstract:
A device and method for the measurement of the thickness of a wet coating, such as paint, on a substrate, the device comprising a frame with two legs having ends which may be pressed through the wet coating onto the substrate. A probe is mounted in the frame and is adjustable towards and away from the frame. An indicating scale is provided to show the position of the probe. The probe has a transparent or translucent tip so that the point at which contact is made with the wet coating may be observed. The method employs a calibration step by setting the device on an uncoated surface of the same shape as the coated surface, thereby avoiding errors due to wear of the device and curvature of the surface.
Abstract:
A dental instrument for simultaneously taking an impression and a bite has a pair of parallel elongated bite tray holders which are laterally spaced apart and are connected together at one of their adjoining ends by a connector wire loop. A manipulating handle is fixed to one of the tray holders at the end opposite to its connected end and has an inner fixed leg portion which protrudes from the instrument at a close obtuse angle to pass the lip of a patient and has an integral free outer end portion that extends from the inner end at a sharp angle of at least 90.degree. for easier manipulation beyond the cheek of the patient by an operator. A bite tray is removably and slidably carried by and positioned between the tray holders.
Abstract:
An apparatus for transforming the water vapor in the atmosphere into liquid water comprising a precipitating chamber, a mixing chamber, heat transfer system, and means for moving atmospheric air through the system.A method of producing liquid water from the atmosphere comprising the steps of passing a first stream of air past a heat absorbing element of a heat transfer system to cause water to precipitate onto the heat absorbing element; mixing the first air stream with a second air stream; passing the mixed air streams past the heat dissipating element of the heat transfer system; varying the proportion of amount of air from the first and second air streams to a predetermined ratio which is a function of the atmospheric conditions.
Abstract:
A rheometer for measuring viscoelasticity with a complex rigidity function comprises a tube for holding the fluid, means for oscillating the tube in the direction of its axis, detector means for detecting the position of the sample of fluid, and an analyzer for relating the movement of the fluid sample to the movement of the drive to derive viscosity characteristics.
Abstract:
The invention relates to a portable plating system that operates stand-alone with a battery power source, or with an A.C. power source. The system is also capable of working from an automobile battery as the power source. The system is packaged in a combination storage/work station unit which stores the plating equipment when not in use, and serves as a work station when the equipment is assembled and ready for use.
Abstract:
A film thickness gauge for measuring the thickness of paint, etc. has a magnet which is placed on the surface to be attracted by a magnetic substrate. The magnet is withdrawn by spring tension. A withdrawal member is braked when the magnet is released and the position of the withdrawal member on release is indicated in terms of the thickness of the coating.
