  • Publication number: 20200338596
    Abstract: An apparatus for removing lightweight debris from a debris-contaminated stream of heavier material. The apparatus includes an enclosed chamber having a material inlet, a chute having a free portion through which the stream can freely fall due to gravity, and a material outlet positioned below the chute. A material stream flows into the chamber via the inlet and then a portion of the stream falls through the free portion and exits the chamber via the outlet. An airflow pathway guides airflows into the chamber via an airflow inlet and out of the chamber via an airflow outlet. An airflow flowing through the airflow pathway that separates a first portion of the debris-contaminated stream from a heavier portion of the debris-contaminated stream. The airflow then carries the first portion out of the chamber via the airflow outlet.

  • Patent number: 6606823
    Abstract: The present invention is a modular roof covering made up of a plurality of interlocking modular trays having moisture or water absorbing component or medium in the tray to absorb moisture and allow it to evaporate or otherwise dissipate over time. The trays interlock with each other and are held down by weights or other ballast to secure the trays to the roof without having to create a physical connection between the trays and the roof structure. The modular roof covering can be made up of different types of tray assemblies, where some have vegetation growing in the tray, others have merely water absorption and dissipation capability, while others have photovoltaic cells for the collection and use of solar energy. The present invention provides a light weight, low cost roof covering system for extending the life of current roof structures, and to restore and protect the environment, moderate and aid in controlling building temperature, manage stormwater runoff and collect and utilize solar energy.

  • Patent number: 5544505
    Abstract: A lock bracket comprises two bracket members which cooperate to define an area between them to secure together two adjacent objects. The bracket members are movable relative to each other between an open orientation, in which the lock bracket can be placed around or removed from the two adjacent objects and a closed orientation in which the two adjacent objects can be held securely in the area defined between the two bracket members. Each of the two bracket members has a padlock receiving area and the two padlock receiving areas cooperate when the lock bracket is in its closed orientation.

  • Patent number: 5028661
    Abstract: Compounds useful as adhesion promoters for thermally cured thiolene adhesives include a) acrylic or norbornene acid phosphate esters such as ##STR1## b) maleic, acrylic, methacrylic, norbornene dicarboxylic, and fumaric acids and half acid esters and peresters of maleic fumaric and norbornene dicarboxylic acids; and c) norbornene, acrylic or methacrylic silanes having two or three hydrolyzable groups bound to the silicon atom thereof, such as 5-(triacetoxysilyl) norbornene.The adhesion promoters may be employed as surface primers for conventional thiolene compositions. Alternatively the thiolene compositions themselves may be modified by addition of 0.1 to 10% by weight of the adhesion promoter. Preferred thiolene compositions employ norbornene functional ene ingredients.

  • Patent number: 4990281
    Abstract: A composition useful as an adhesion promoting primer activator for cureable acrylic monomer formulations, particularly anaerobic cureable formulations, comprises a solution in a volatile organic solvent of a Cu(II), Co(II), Mn(II), Mn(III), or Cr(III) salt of an acid phosphate acrylic monomer. The acid phosphate monomer may be one of the formula: ##STR1## where R.sup.1 is H or methyl, R.sup.2 is a divalent organic group having 2-40 carbon atoms and A is OH or CH.sub.2 .dbd.C(R.sup.1)C(.dbd.O)OR.sup.2 O--.

  • Patent number: 4916184
    Abstract: An adhesive composition comprising a component which is polymerizable or cross-linkable with a peroxy initator, e.g., a (meth)acrylic ester monomer, thiolene resin, or tough acrylic copolymer, and an initiator of the formula: ##STR1## wherein: R.sub.1 is H or lower alkyl; and R.sub.2 is H or --OR.sub.3, where R.sub.3 is H or lower alkyl.An appertaining method of bonding substrates, and bonded articles formed thereby, are also disclosed. The adhesive composition of the invention is particularly advantageous in bonding of metal substrates, on which the maleic acid peroxy compounds of the invention produce surface bonding enhancement of the adhesive composition, relative to the use of conventional polymerization/crosslinking peroxy initiators such as t-butyl perbenzoate.
