Abstract: A dust neutralizing and flocculating system used in an air cleaning system for removing contaminants contained in indoor air including a radio frequency generating electrode and an ion generating electrode. Fine particles passing through a moderately efficient filter equipped in the air cleaning system sequentially pass through the radio frequency generating electrode and ion generating electrode. The fine particles are dipolarly magnetized while passing through the radio frequency generating electrode, thereby exhibiting an increased inter-particles attraction. The ion generating electrode adds cations and anions to the fine particles, thereby promoting the flocculation of the fine particles circulating in the room installed with the air cleaning system. By virtue of the promoted flocculations, the particle size of the particles circulating in the room increases. The particles with an increased size are secondarily removed by the filter.

Abstract: An improved small animal restraint device is provided which enables an inidual to conduct ocular examinations of a small animal. The device minimizes manipulation of the eyes of the animal and eliminates recovery time associated with anesthetics, while also reducing examination time. The restraint device comprises a cylinder having a longitudinal slot in the wall thereof. A conical member which is attached to one end of the cylinder includes a pair of eye openings in the upper wall thereof and a nose opening at the apex thereof. A plunger placed in the cylinder at the other end thereof assists in holding the animal in place. A set screw, which extends through the slot in the wall of the cylinder, secures the plunger in place.
