Zinc primary

All conventional phosphate coating processes are based on dilute phosphoric acid solutions of iron, manganese and zinc primary phosphates either separately or in combination. The free phosphoric acid in these solutions reacts with the iron surface undergoing treatment in the following manner ... [Pg.707]

Electronic Time Fuze. Development of an electronic time fuze which would be substantially more accurate than exisitng time fuzes is described in the report of Texas Instruments, Inc (Ref). A programmable digital circuit is driven by. an oscillator based on a Picatinny Arsenal design. As power source, two types of battery, a silver-zinc primary battery and a reserve battery which uses ammonia as the electrolyte, were tried. A detailed manufacturing plan is included as an appendix... [Pg.717]

Prismatic 9 V three-cell batteries, and 6 V two-cell ultrathin batteries are also manufactured. The former is designed as a high capacity replacement for aqueous zinc primaries and the latter for smart cards. [Pg.128]

Nevertheless, both hazardous and inert residues are solid wastes and require landfill. Dumping solid waste to landfill, even non-hazardous clean wastes, is not sustainable and is not entirely green . An ideal green technology is one that consumes all materials involved in the production process to produce only re-useable or new products, without generating solid waste that requires disposal to landfill. Such smelters can be found in Trail, British Columbia, Canada at the Cominco lead and zinc primary smelter and in Malaysia in Kuala Lmnpur at the Metal Reclamation primary and secondary lead smelter [21].

The Li/SOj batteries are manufactured in a number of cylindrical cell sizes, ranging in capacity to 35 Ah. Some of the cells are manufactured in standard ANSI cell sizes in dimensions of popular conventional zinc primary batteries. While these single batteries may be physically interchangeable, they are not electrically interchangeable because of the higher cell voltage of the lithium cell (3.0 V for lithium, 1.5 V for the conventional zinc cells). Table 14.9 lists some of the sizes and rated capacities of Li/SOj batteries that are currently manufactured. [Pg.353]
