  • Patent number: 6033614
    Abstract: A manual loader for use in bypassing an automatic pellet feeder for an automold machine used to encapsulate integrated circuit assemblies in plastic. The loader has a support mounted adjacent the mold section of the machine. The loader also has at least one pellet boat which moves relative to the support into and out of said mold section. The pellet boat includes one or more pellet pots which are adapted to receive and hold a solid pellet of material. The loader has a release mechanism which is movable between a blocking position and a release position. The release mechanism retains the pellets in the pellet pots in the blocking position and releases the pellets from the pots when manipulated to the release position for dropping the pellets into a mold of the machine's mold section.
    Type: Grant

  • Patent number: 5050356
    Abstract: A foundation for supporting poles, particularly electrical power cable support poles, is formed by boring a hole only slightly larger than the pole base onto the earth a desired depth. A reinforcing structure is lowered into the hole. The reinforcing structure usually rests on the bottom of the hole and extends above the earth surface a number of feet. The hole is then filled with concrete, usually up to the earth surface, and allowed to cure. A lowermost or base section of the pole is then lowered into position about an exposed upper portion of the reinforcing structure. Concrete is placed into the interior of the pole section about the reinforcing structure until it is covered. After the concrete cures, any remaining pole sections may be installed onto the base section.

  • Patent number: 4976977
    Abstract: The present invention contemplates a particulate, free-flowing pelleting agent with energy value. The pelleting agent is constituted by discrete, free-flowing absorbent clay agglomerates that include clay and molasses in a clay-to-molasses weight ratio of at least about 1.5:1, respectively.

  • Patent number: 4775473
    Abstract: An absorbent article suitable for absorption of aqueous as well as oleaginous liquids such as metal cutting fluids, hydraulic fluids, oils and the like is disclosed. The absorbent article is a spunlaced material sleeve closed at both ends and filled with an inherently flameproof particulate material, such as particulate clay material, having a certain particle size range. The spunlaced material is liquid permeable, oleophilic, and hydrophilic. The spunlaced material also has a liquid wicking rate that is at least equal to that of the particulate clay material contained within the sleeve. Preferred spunlaced materials are woodpulp/polyester spunlaced materials having a woodpulp-rich face and a polyester-rich face. The polyester-rich face is situated contiguous to the particulate absorbent material.

  • Patent number: 4605801
    Abstract: The process is an improvement over the chlorination of EDC in a boiling bed. The reactants, chlorine and dichloroethane (either 1,1- or 1,2-) are mixed in the vapor phase and passed over a molecular sieve which serves as a catalyst to produce 1,1,2-trichloroethane.

  • Patent number: 4359891
    Abstract: A repetitive gas chromatograph employing a backflush valve downstream from the detector and a separate sample injection valve located upstream located directly upstream from the single chromatographic column. Each valve is operated independently of the other so as to allow flexibility in the timing of going into backflush operation and returning the sample valve immediately after sample injection onto the column to sample passage through the sample valve so as to more quickly establish equilibration of the sample and the sample valve's walls. Type and location of sample valve and backflush valve allow continuous monitoring of a sample stream.
