Abstract: A method of marking a thermoplastic article can comprise: combining a thermoplastic with a light-marking additive to form a composition, forming the composition into an article having a maximum optical absorption wavelength; and illuminating, at a marking wavelength, at least a portion of the article with a device having a power of less than or equal to about 200 mW, to form a light-mark. The light-mark can have a size, as measured along a major axis, of greater than or equal to about 10 micrometers. The light-mark can also have a mark absorption wavelength that is greater than or equal to about ±100 nm of the maximum optical absorption wavelength, and can have a spectral absorption curve.

Abstract: The packaged medical article can comprise the medical article and a protective layer capable of inhibiting exposure of the medical article to a color change activator prior to use of the medical article. The medical article comprises a plastic portion and an active color changing specie, wherein the color changing specie is capable of changing color after exposure to a color change activator. The method for producing a medical article can comprise: combining thermoplastic resin with a blocked color changing specie to form a resin mixture and manufacture processing the resin mixture to form a packaged medical article. This manufacturing processing comprises forming the resin mixture into the medical article and packaging the medical article to form a packaged medical article. The color changing specie will not affect the structural integrity of the medical article when it changes color.

Abstract: A Harness for towing a golf cart includes an adaptable part, which attaches to the different types of handles of golf bag pull carts. Another adaptable part of the Harness fits around the waist/hip of any size golfer and is easily and quickly attached and detached to facilitate use of the Harness while walking the golf course and playing golf. A final adaptable part of the Harness connects the two previously mentioned parts to one another and adjusts for pull cart balance characteristics and golfers' physical dimensions and stride lengths. Using this Harness facilitates comfortable walking with upper body completely unencumbered by carrying a golf bag or grasping the handle of the pull cart.

Abstract: A housing assembly and method for use on sanitary mixers and similar equipment that includes a cover sealed by sealing elements and supported by supporting elements. The cover covers at least a part of a drive component of the mixer such as a speed reducer.

Abstract: A twist ring for placement in an annular groove having a generally C-shaped region with two ends. The twist ring has a first leg extending from one end and a second leg extending from the second end. The twist ring additionally has at least one finger projecting inwardly from the C-shaped region.

Abstract: An assembly for supporting a rotatable shaft assembly of mixers and similar rotating equipment that includes a first bearing set and a second bearing set. The first and second bearing sets surround and support the rotatable shaft assembly at respective axial locations.

Abstract: An impeller for use in a mixing apparatus having a rotating shaft has at least one longitudinal member extending substantially radially from the shaft; and a plurality of individual impeller segments each having a bore therethrough. The segments are stacked together with the longitudinal member extending through said bores. The longitudinal member may be an at least partially threaded rod or may be a beam. A method of assembling an impeller for use in a mixing apparatus having a rotating shaft employs the steps of stacking a plurality of individual impeller segments onto a longitudinal member that extends substantially radially from the shaft; and fastening the stacked impeller segments onto the longitudinal member to retain the impeller segments on the longitudinal member.

Abstract: Disclosed is an advertising and distributing device which is adapted to be stuck on a newspaper, magazine, catalogue, envelope, parcel, package or other similarly distributed print medium. A pressure-sensitive adhesive is applied to a back face of a first layer and to a back face of a second layer with located in between the promotional material per se. Preferably, there is also provided a peel off layer to which is attached the back of the second A device for advertising and distributing printed materials including at least one printed material, said device having a first layer having an adhesive applied to one surface thereof, a second layer having an adhesive applied to one surface thereof and a peel off layer, said peel off layer protecting said adhesive surface of said second layer prior to affixing to a host layer prior to removal for sticking to the print medium.

Abstract: A system for personalizing a mailer includes a controller receiving information identifying the intended recipient of the mailer. In response to this information, the controller selects information to be printed on the exterior of the mailer, with the information to be printed being personalized for the intended recipient. A printer is responsive to the controller to print the personalized information on the back exterior surface of the mailer. A method for personalizing a mailer is also disclosed.

Abstract: A vibrating toothbrush, which includes a handle member, an elongated arm which has a brushhead at the distal end thereof, and a drive assembly for moving the brushhead at a selected velocity. Responsive to an on/off switch on the toothbrush is an on/off variable, which enables a master clock to produce a drive signal, the on/off variable being reset by a 120-second timer. A quadtimer variable, when in the enabled state, is responsive to the on/off switch to produce an audible signal and a difference in brush velocity at 30-second intervals within the 120-second period.

Abstract: The brush element (10) includes a base (14), the base (14) including a connecting portion (18) at one end (16) thereof, which is capable of receiving the lever arm (15) of a vibrating toothbrush. Successive lateral rows of spaced bristles (19-27) are anchored in the brush base (14), in a pattern comprising two successive rows of full length bristles which are configured so that the tips of each two rows form a peak, followed by a third row of shorter bristle portions which are approximately 0.2 inch shorter than the full length bristles.

Abstract: A method and apparatus for demobilizing the motile subgingival bacteria and for removing soft plaque from the teeth on a substantially daily basis as a means to prevent, treat and/or limit periodontal diseases. A piezoelectric multimorph transducer is used to generate low-energy vibrations, these vibrations are applied to the teeth and gingival fluids to cause mild cavitation within the fluid to remove subgingival plaque and to demobilize motile bacteria. An electronic circuit for driving the transducer at its resonant frequency or multiples thereof and for electrically isolating the user are included.
