Filed:

Aug 29, 2006

Appl. No.:

11/511770

Inventors:

Glenn A. Fodor - Hampton NJ, US
Virginia M. Cunningham - Hampton NJ, US

International Classification:

A01D 34/00

US Classification:

56 137

Abstract:

A recycling grass mulching device for a rotary lawn mower has (a.) a main housing having a grass ingress port and a grass egress port; (b.) a mulching device contained within the main housing, the mulching device including a central shaft, a central shaft drive take-off, and a plurality of mulching lines extending outwardly and away from the central shaft wherein the drive take-off is selected from the group consisting of a pulley attachment, a gear attachment, a chain attachment, and a drive shaft attachment. The lines are typically heavy duty weed whacker type lines, i.e. thick, flexible plastic cord, or metal wire or rod or strip, flexible or rigid. The recycling grass mulcher main housing is adapted to be mounted onto a rotary lawn mower, with the grass ingress port being connected to a grass cutting area of the rotary lawn mower, e.g. the grass is expelled from cutting chamber(s) into the mulching device. The mulching device may be a lawn mower retrofit or attachment or it may be an integral part of the lawn mower.

Appl. No.:

5/823569

Inventors:

Virginia L. Cunningham - Hatboro PA

Assignee:

Rohm and Haas Company - DE

International Classification:

C08F 218

US Classification:

521 38

Abstract:

Novel crosslinked ion exchange resins derived from dimethylaminoethyl methacrylate are disclosed together with their process of manufacture by suspension polymerization preferably utilizing a trialkylamine phase extender. Trialkylamines are found to be useful generally as phase extenders for the preparation of other polymeric materials by the known methods of suspension polymerization.
