Abstract: An end-effector is disclosed including an ultrasonic blade configured to acoustically couple to an ultrasonic transducer and electrically couple to a pole of an electrical generator and a clamp arm including a clamp jaw and a cantilever electrode fixed to the clamp jaw. The cantilever electrode is configured to electrically couple to an opposite pole of the electrical generator. The clamp arm may include an I-beam shaped clamp arm pad and the cantilever electrode is disposed between the I-beam. The clamp jaw, the cantilever electrode, and the clamp arm pad may define recesses along a length coinciding with the ultrasonic blade. The clamp arm pad may be fixed to the clamp jaw and disposed between the clamp jaw and the cantilever electrode and may extend beyond the surface of the cantilever electrode. The clamp arm may include a stationary gap setting pad and movable floating gap setting pads.

Abstract: A guitar bridge-pin removal tool has a solid body sized to fit in a users hand and opposite surfaces that can be gripped between the thumb and fingers. A channel is disposed across one end of the solid body. Such channel has a main cross section that approximates that of a head of a bridge pin that retains a string in a guitar. A necked outer edge runs along the longitudinal lips of the channel and captures the head of said bridge pin along any portion. At least one side end in the channel is open to allow the head of the bridge pins to be slipped in and out.

Abstract: The toy combination includes a toy vehicle having one or more pairs of spaced apart shoulders on exterior sides of the vehicle body and one or more toy attachments releasably secured on the pairs of shoulders by snap-fitting a respective pair of rails on the toy attachment against a respective pair of shoulders. The toy attachment includes resilient extensions on which the rails are carried. The extensions are flexed to snap-fit the rails on the shoulders. The toy attachment can include first and second pairs of extensions adjacent opposite ends with a receptacle intermediate the extensions for releasably receiving a toy figure.

Abstract: A process for the continuous mass polymerization of olefinically unsaturated monomers in the presence of a polymerization initiator. The polymerization is carried out in one or more tubular reactors provided with internal static mixing elements. A portion of the reaction mass produced in the reactor is recirculated back to the reactor as feed.

Abstract: Polymerization products of carboxyl-free and carboxylsubstituted ethylenically unsaturated monomers have retained with the resin a reaction solvent mixture of high boiling alcohols, of which about 30 to 60% are normally liquid, waterinsoluble alcohols. These products are solid, hard glass-like resins which may be dissolved in aqueous bases to form clear or cloudy substantially colorless coating solutions useful in the preparation of clear or cloudy aqueous floor polishes which deposit clear protective films on treated floors.
