Methods and apparatus for screening diverse arrays of materials are provided. In one aspect, systems and methods are provided for imaging a library of materials using ultrasonic imaging techniques. The system includes one or more devices for exciting an element of the library such that acoustic waves are propagated through, and from, the element. The acoustic waves propagated from the element are detected and processed to yield a visual image of the library element. The acoustic wave data can also be processed to obtain information about the elastic properties of the library element. In another aspect, systems and methods are provided for generating acoustic waves in a tank filled with a coupling liquid. The library of materials is then placed in the tank and the surface of the coupling liquid is scanned with a laser beam. The structure of the liquid surface disturbed by the acoustic wave is recorded, the recorded disturbance being representative of the physical structure of the library. In another aspect of the invention, a mechanical resonator is used to evaluate various properties (e.g., molecular weight, viscosity, specific weight, elasticity, dielectric constant, conductivity, etc.) of the individual liquid elements of a library of materials. The resonator is designed to ineffectively excite acoustic waves. The frequency response of the resonator is measured for the liquid element under test, preferably as a function of time. By calibrating the resonator to a set of standard liquids with known properties, the properties of the unknown liquid can be determined. An array of library elements can be characterized by a single scanning transducer or by using an array of transducers corresponding to the array of library elements. Alternatively, multiple resonators of differing design may be used to evaluate each element of a library of elements, thus providing improved dynamic range and sensitivity.

A working machines includes an identifying unit. A force sensor detachably supports a working head in the identifying unit. A controller circuit is designed to identify the working head based on the load detected at the force sensor. When the working head is replaced with another one, the load changes in the force sensor in the identifying unit. In general, the individual working head has the specific weight. The working heads can thus be differentiated from each other based on the weight. Accordingly, the controller circuit is allowed to reliably identify the working head after the replacement with a higher accuracy based on the detected load.

Modified mineral fillers, derived from either a coarse particle kaolin clay or a coarse particle ATH, having excellent utility in thermoset polymers as low paste viscosity fillers are disclosed. The method of treatment involves the use of specific weight ratio combinations of a silane and a long chain aliphatic alcohol. The treatment of clay can also involve the auxiliary use of a surfactant in small amounts, which is utilized to emulsify the silane and aliphatic alcohol treatment components in water either individually or as a co-emulsion blend prior to their addition to the clay. The surfactant, which is preferably a nonionic surfactant having a HLB value of 12-18, aides in uniformly treating all the clay particle surfaces with the silane/alcohol treatment combination. Coarse particle clays having general utility in the invention are those having an average Stokes equivalent particle diameter of at least 3.0 microns, while the coarse particle ATH fillers having general utility in the invention are those having a BET surface area value less than 5.0 m2/g. Clays or ATH so treated with the inventive silane/alcohol treatment provide unique viscosity reduction benefits in thermoset polymers unattainable by using either treatment additive alone in any amount. This low viscosity characteristic allows the treated mineral products to be used at high loadings in various thermoset compounds, as fillers or extenders, which is advantageous in terms of reducing cost and/or gaining certain performance properties, such as physical reinforcement, composite surface smoothness or flame retardancy.
