  • Retainer clip for mounting sink to countertop
    Patent number: 6793190
    Abstract: A retainer clip includes a ratchet plate and a cooperating pawl for anchoring a sink to a countertop with a press-in, above-counter installation. The ratchet plate has a plurality of detents and is affixed to an edge of a cutout in the countertop. The pawl includes a spring element mountable to the sink and has at least one upwardly angled, resilient tab which successively engages the ratchet plate detents with a one-way action as the sink moves downwardly in the cutout. When the sink is fully inserted, the tab seats upwardly in a detent of the ratchet plate. In an embodiment, the pawl includes multiple tabs having slightly different lengths to provide an installation tolerance that is less than an incremental distance between ratchet plate detents.

  • Reduced polymer buildup in condenser of reactor vessel
    Patent number: 4487899
    Abstract: This invention relates to a suspension polymerization process for polymerizing vinyl monomers in a reaction vessel equipped with an external cooling means, such as a reflux condenser, as well as a cooling jacket, wherein polymer buildup in said external cooling means can be substantially eliminated. This is accomplished by adding in a plurality of charges to the reaction mixture nonionic surface active or wetting agents having a hydrophile-lipophile balance (HLB) in the range of from about 9 to about 16 thus resulting in reducing charge expansion and attendant reduction in foaming of the charge.
