A holder for removably supporting a compact disc or other object with a hole in the center. The compact disc is supported by at least two arms which are held on a flexible step. The arms have an outwardly extending protrusion which holds the compact disc in place. When it is desired to remove the disc the arms are pressed from above and they hingedly move together and cause the compact disc to pop upwardly from the arms.

There is disclosed a welding rod holder arrangement including a welding rod receiving member of electrically conductive material and having a welding rod receiving and contacting portion that is externally tapered so as to frictionally receive an electrically conductive loop on the end of a welding electrode or wire. The welding rod receiving member is slotted for air-cooling purposes and a slotted casing means of insulating material surrounds a substantial portion of said welding-rod-receiving member while leaving exposed a sufficient length of said externally tapered offset portion as to provide a large surface area for electrical contact with the electrically conductive loop. There is also disclosed a welding electrode or welding wire having an integrally formed electrically conducting eye or loop at one end thereof that ensures a substantial area of contact with the externally tapered portion of the welding-rod-receiving member.

A regeneratable adsorber for adsorbing adsorbable contaminates from a fluid stream containing same is disclosed. The adsorber includes an adsorber housing in which there is a fluid stream inlet and a fluid stream outlet. The adsorber also includes a plurality of adsorber chambers which are arranged in an indexable wheel configuration. Each chamber includes an electrically conductive adsorbent, such as a monolithic activated carbon, a set of electrical conductors in contact with the adsorbent, and an inlet and outlet. A chamber is either in contact with a source of contaminate fluid or a desorbent fluid used to regenerate the adsorber. The adsorber includes selectively indexed chambers for adsorption or desorption to provide continuous contaminate adsorption and regeneration.

A fish lure making system for making a fishing lures for fish eggs and other baits. The fish lure making system includes a tying means for making the fishing lures. A spool is provided for holding the tying means. A sack is provided having an access opening designed for holding fish eggs. A housing having an interior is provided for selectively receiving and holding the sack. The housing includes a pair of clip portions and a securing portion. The spool is rotatably mounted between the pair of clip portions of the housing. The securing portion of the housing includes an aperture extending through the housing for receiving the sack. A securing assembly is slidably positioned in the interior of the housing for cinching the sack positioned through the aperture while user ties the sack blocking the access opening of the sack.
