Abstract: A gauge head is attached to the grindstone holder of an NC gear grinding machine, and the tooth profile, tooth trace, gear pitch, etc. of a ground gear are measured on the NC gear grinding machine by actuating the control functions of various parts provided on the machine without detaching the gear from the machine. The gauge head attached to the grindstone holder can be retracted from a position where the gauge head contacts with the tooth flank located between the grinder and the gear of the ground gear on the grinding machine to a position where the gauge head does not interfere with the wheel during grinding operation, so that the wheel need not be detached from the machine even during the gear measurement.

Abstract: A dryer is designed as a closed system in which heated air used to dry the materials is continuously recycled within the drying compartment of the dryer without being discharged to the atmosphere, thus increasing the efficiency of the system while preventing the discharge of contaminated vapors to the atmosphere and also conserving energy which would otherwise be required to heat or air-condition the air drawn into the dryer from the building in which the dryer is located. A regenerative heat exchanger and an atmospheric cooler/condenser are provided in the dryer and condense and remove moisture from the saturated air and transfer the heat of condensation back into the air before the air is reheated and recycled back to the materials to be dried. The drying compartment may comprise an enclosed tunnel through which a rack of superposed trays are conveyed or may comprise some other conveying mechanism.

Abstract: A process and apparatus are described for rapidly drying a wet, porous gel monolith of glass or ceramic, at subcritical temperatures without inducing any cracking of the gel. The wet gel is immersed in a liquid solvent in a chamber, and the liquid solvent is then heated and expelled from the chamber. Further heating, with or without the presence of a flowing inert gas, fully dries the wet gel. When an inert gas is used, the gas is delivered to the chamber with a controlled solvent partial vapor pressure, to correspondingly control the driving force for drying the gel.

Abstract: The invention provides an apparatus and a method for controlling pests which, according to one aspect of the invention, uses a laser beam which is scanned over a defined area and incapacitates sensory organs of various pests when they enter the defined area. Such a pest control system uses a laser source in cooperation with a scanner which then repetitively scans the laser beam throughout the defined area. Any pest which wanders into this area, or is attracted into this area, is likely to sense the laser beam, typically through its eyes or light spot. The laser beam is of sufficient energy to destroy the sensory organ and incapacitate the pest.

Abstract: Modular building panels having foam cores protected by metal skins are releasably interconnected in edge-to-edge relation to one another. The interconnection is accomplished by bending the metal skins that protect the top and bottom surfaces of the core into complementary shapes so that contiguous panels are snap fit together when the bent metal skins are interlocked with one another. In some embodiments, the cores are grooved and the flexibility of the interlocking members is increased by decreasing the depth of the grooves and the flexibility is decreased by increasing the depths of those grooves because decreasing the groove depth provides less support for the interlocking members and allows them to displace more during the interlocking procedure and increasing the depth increases the support and thus limits their movement.
