  • Patent number: 8727102
    Abstract: At least one single link of a conveyor chain is configured to support a tension load cell. A main body portion of the link includes a central cavity sized to contain the load cell, which has been inserted therein through an opening of the main body portion, and at least one auxiliary cavity to contain at least one battery cell and circuitry. A cap portion of the link closes off the opening into the cavity to enclose the load cell therein. One or both of the main body and cap portions may include a bore to receive a fastener for attaching to an end of the inserted load cell, and both portions include a bore oriented to receive a pin of a mating dual link of the conveyor chain. The cap portion may also include anti-rotation surfaces to mate with one or both of: the load cell and the opening.

  • Patent number: 5799831
    Abstract: A foaming system 10 includes a dual aspirator 13. The dual aspirator 13 has first and second aspirators 80 and 81 to pick up a first and second chemical concentrate. The diluent first chemical mixture is drawn in through the first aspirator 80 and goes through a first diffuser 46 where the first chemical/diluent mixture is further mixed. Similarly, diluent/chemical mixture is drawn by the second aspirator 81 and flows through a second diffuser 47 where it also is mixed. The two diluent/chemical mixtures then combine after exiting the diffusers and the compatible chemicals are then mixed by the flow of the diluent/chemical mixtures. Flushing lines 68 and 71 provide for cleaning of the dual aspirator 13. Further, the diffusers have a ratio of their diameter to length to aid in the prevention of contamination along with the use of two check valves 48 and 49.

  • Patent number: 5597793
    Abstract: The invention is a foam stabilizing composition which is used in conjunction with alkaline detergent products to produce a foam which is capable of clinging to vertical surfaces for extended time periods without breakdown or drying and which ultimately rinses freely with water. The foam stabilizing composition generally comprises a vinyl polymer emulsion. The invention also comprises a method of cleaning hard surfaces using the combination of the alkaline detergent product and the disclosed foam stabilizing composition.
