To complete the assembly of a cell, the interleaved electrode groups are bolted to a cov er and the cover is sealed to a container. Originally, nickel-plated steel was the predominant material for cell containers but, more recently plastic containers have been used for a considerable proportion of pocket nickel-cadmium cells. Polyethylene, high impact polystyrene, and a copolymer of propylene and ethylene have been the most widely used plastics. 

Cell Construction. Nickel—2iac batteries are housed ia molded plastic cell jars of styrene, SAN, or ABS material for maximum weight savings. Nickel electrodes can be of the siatered or pocket type, however, these types are not cost effective and several different types of plastic-bonded nickel electrodes (78—80) have been developed. 

A serrated piece of aluminum used to work a plastic laminate. Purpose of device is to compact a laminate and to break up large air pockets to permit release of entrapped air. 

Pocket and tubular electrodes have been described in detail by Falk and Salkind [1]. McBreen has reviewed work on both sintered plate and plastic-bonded electrode technology [9], More recent work is on the use of nickel foams and nickel mats. 

Coring The term coring in IM refers to the addition of steel to the mold for the purpose of eliminating plastic material in that area. Usually, coring is necessary to create a pocket or opening in the product, or simply for the purpose of reducing an overly heavy wall section. For simplicity and economy in injection molds, cores should be parallel to... 

Very popular is plastic cushioning material used in packaging, usually laminated thermoplastic films that incorporate air bubble pockets. 

In RPs, insufficient compaction and consolidation before plastic solidification or cure will result in air pockets, incomplete wet-out and encapsulation of the fibers, and/or insufficient fiber or uniform fiber content. These deficiencies lead to loss of strength and stiffness and susceptibility to deterioration by water and aggressive agents. 

MATERIALS Pocket watch with plastic crystal, small screw, electric wire, battery, electric blasting cap. 

Emergency Response to Terrorism Job Aid (for Fire/EMS/HazMat/Law Enforcement Personnel) A very well done, pocket-sized manual on plastic stock that actually tells first responders extensive basic information about what needs to be done at a terrorist incident. This handbook was designed, produced and distributed through a joint partnership of the Federal Emergency Management Agency, the United States Fire Administration, and the... 

The nickel-based systems include the flowing systems nickel—iron (Ni/Fe), nickel—cadmium (NiCd), nickel—metal hydrides (NiMH), nickel—hydrogen (Ni/ H2), and nickel—zinc (Ni/Zn). All nickel systems are based on the use of a nickel oxide active material (undergoing one valence change from charge to discharge or vice versa). The electrodes can be pocket type, sintered type, fibrous type, foam type, pasted type, or plastic roll-bonded type. All systems use an alkaline electrolyte, KOH. 

Energy is needed to break such a contact, more so with some joined items than others. If we consider the adhesion of plastic on glass, the highest adhesion will be obtained if the adhesive fills all the valleys and crevices of each adhered body surface. This will remove any air pockets that do not contribute to adhesion. The role of the adhesive or glue is to provide mechanical interlocking of the adhesive molecules. 

The terminology of the elements suffuses our language, sometimes divorced from the questions of composition to which it once referred. Plumbing today is more likely to be made from plastic pipes than from the Romans (lead) the lead in pencils is no such thing. Cadmium Red paints often contain no cadmium at all. Tin cans have no more than the thinnest veneer of metallic tin it is too valuable for more. The American nickel contains relatively little of that metal. And when was the last time that a Frenchman s pocketful of jingling argent made of real silver ... 

A couple minutes later, Amanda and the guy walked over to Hannah to join her. Amanda was acting weird, detached. The guy nodded his head at Hannah, gave her a siick smirk, and pulled a little plastic bag out of his pocket. Little white pills. Who is this guy and what are those , she thought. And what s up with Amanda The guy asked her if she wanted one of the pills, told her that her friend said she might be interested in having a good time, too. Amanda smiled and nodded, as if to say that the guy was cool and Hannah should definitely take him up on his offer.
