  • Publication number: 20120216742
    Abstract: A timing whistle for setting the timing of an internal combustion engine comprising: a threaded tip, where the tip provides a means for coupling the whistle into a spark plug port; a means to rotate and secure the whistle into the spark plug port; a body portion, where said body portion extends from the means to rotate and secure; and an opening along the body portion, where said opening provides a means for the emission of a whistling sound indicating optimum timing of the engine. In one particular embodiment, the means to rotate includes a bolt type assembly and the body portion includes a pipe and a cap attached to the bolt assembly.

  • Patent number: 6677398
    Abstract: An aqueous ink binder including 30-60%, by weight based on the dry weight of the binder composition, of a first polymer including, as polymerized units, 15-75%, by weight based on the weight of the first polymer, ethylenically unsaturated carboxylic acid monomer having a pKa from 2.0 to 4.6, the first polymer having a calculated Hansch parameter from 1.3 to 2.1, and 70-40%, by weight based on the dry weight of the binder composition, of a second polymer, the second polymer being an aqueous emulsion polymer is provided. Also provides are a clear or pigmented ink composition and a method for providing an ink which has press resolublility and, as a dry film, water resistance.
