Jamerco of City of Industry Calif., introduces its new Air Palm-Hammer. The palm-sized pneumatic tool has an operating pressure-range of 50-120 PSI and a consumption of 2-4 CFM. It drives a variety of nails and spikes. Operation is triggerless and is performed by pressing the loaded nailer down over the target. The kit includes a standard common nail attachment, a magnetic tip usedjetdrillpress attachment which holds nails in place, a finish nail attachment, a hammer attachment and a complete maintenance kit. A leather glove is also included. In the production of pig iron, brick and refractory usedjetdrillpress materials are used to form the very large ovens or retorts (coke ovens) in which coal is converted to coke. Refractory and brick materials are needed to line huge shaft-like blast furnaces in which the molten pig is formed. The auxiliary furnaces or hot blast stoves, which heat the air usedjetdrillpress for the blast furnace, are also lined with refractories. The molten pig iron from the blast usedjetdrillpress furnace is then sent to a brick- or refractory-lined ladle. The molten pig iron is then poured into a brick- or refractory-fined pig casting machine, where the pig iron is formed into large castings and cooled.
