A static dissipative touch device is provided for discharge of static electricity. The device is attached directly or immediately adjacent to electronic equipment which is susceptible to damage from static electricity. The device is electrically conductive and is readily contacted by the user of the equipment prior to use, to drain off the static electricity and discharge it to ground.

The inventive applicator has a pliable plastic tube for holding a hermetically sealed crushable glass ampoule containing fluid to be dispensed from the applicator and applied by the applicator to a surface, and a pliable dispensing member mounted onto the plastic tube. The dispensing member has a dauber from which the fluid is dispensed and a protective device which surrounds a portion of the tube and is squeezed inwardly between the user's forefinger and thumb to cause the portion of the tube positioned thereunder to deform inwardly and crush the crushable glass ampoule positioned within the tube to release the fluid contained within the ampoule. The protective device guards against and minimizes the chances of users being cut by glass shards of the crushed glass ampoule when the protective device is subsequently squeezed inwardly to cause the fluid to move through the applicator to the dauber.

An eraser for removal of dry ink dust and for conditioning of white boards, which includes a stack of fabric layers which may be treated with cleaning and anti-static compounds. The fabric layers are of semi-rectangular shape which wrap around a jacket cover which is folded over a center core and joined together, the fabric layers have tab dispensing ends and other ends which are fastened to the cover and core by a single staple which spans the ends, the ends to permit the layers to be removed one at a time.
摘要:
A ratchet handle of generally spherical shape, the handle having an embedded ratchet mechanism near one surface, the drive post of which is accessible through a diametrical channel extending from the opposite side of the sphere. An extension rod inserted into the channel mates with the drive post and extends beyond the opposite surface of the handle a selected distance to a socket wrench which may be used to drive a fastener of corresponding size. Supplemental male and female post recesses accept additional extension rods serving as lever handles and fixed, non-ratcheted drives.
