Abstract: An embodiment includes an apparatus comprising: a hollow needle with a narrowed inner diameter in a distal third of the needle; and a flexible chord coupled to proximal and distal conduits; wherein the distal conduit is in the needle and distal to the narrowed inner diameter and the proximal conduit is in the needle and proximal to the narrowed inner diameter; wherein: (a)(i) long axes of the proximal and distal conduits are substantially parallel to a long axis of the needle when the proximal and distal conduits are in the needle, and (a)(ii) the proximal and distal conduits are configured to rotate when deployed from the needle such that their long axes are not parallel to a long axis of the chord when the chord is fully extended. Other embodiments are described herein.

Abstract: An apparatus for attachment to a bucket for holding a liquid is attached to a bucket with an upper rim. A bail is pivotally attached to the bucket as in a conventional arrangement, the bail having an upper position and a lower position. The apparatus has a housing with a pump operatively attached thereto, the pump having an inlet in liquid communication with the bucket and an outlet for facilitating the pumping of liquid from the bucket, preferably through a spray wand with a nozzle at the outlet thereof. A member is pivotally attached to the housing at one end thereof and has a notch in another portion thereof. This member has at least a first pivotal position and a second pivotal position. When housing is on the rim, the bail is in the upper position thereof and the member is in the first pivotal position thereof so that a portion of the bail is in the notch for thereby holding the housing to the upper rim of the bucket.

Abstract: A "closed-loop" moisture control system for use in vibratory mass finishing systems. A substantially constant amount of a grinding and/or polishing slurry is maintained in a finishing reservoir of the vibratory mass finishing system by controlling the amount of such fluid flowing from a supply reservoir into the finishing reservoir, and/or the amount of such fluid flowing from the finishing reservoir into a collection reservoir. In operation, a total weight of the supply reservoir and its contents, and of the collection reservoir and its contents is monitored and, in the event there is an increase in the total weight, a control means increases the amount of polishing fluid flowing from the supply reservoir into the finishing reservoir, and/or decreases the amount of polishing fluid flowing from the finishing reservoir into the collection reservoir.
