Rotational firing

In Fig 4, Method A is for single shots Method B is for multiple shots or rotation firing in wet holes and Method C for multiple shots or rotation firing in dry holes or for wet holes providing plastic covered fuse is used... 

In Fig 5, Method A is for firing with instantaneous electric blasting caps and Method B is for instantaneous firing and for all rotation firing with delay electric blasting caps... 

The use of this lighter insures better results in rotation firing and allows more time for. the blaster to retire before the detonation of the first charge, since he has only the pilot fuse to light. The use of this type of fuse has the disadvantage of requiring large amounts of fuse (Ref 4)... 

The Hartford-Empire 28 is a press-and-blow machine used to make articles such as drinking glasses (tumblers). It uses paste molds and the ware is rotated to avoid the mold seams jars with screw threads cannot be produced. The product leaves the machine as an almost closed, hoUow object and is finished by severing and fire-polishing with a bum-off machine. 

Auxiliary Equipment On direct-heat rotating equipment, a combustion chamber is required for high temperatures and finned steam coils are used for low temperatures. If contamination of the produc t with combustion gases is undesirable on direct-heat units, indirect gas- or oil-fired air heaters may be employed to achieve temperatures in excess of available steam. 

An operator had tested dryer samples on a number of occasions. After the last sampling, he closed the manhole cover, put the dryer under vacuum, and started rotation of the dryer. A few minutes later an explosion and flash fire occurred, which self-extinguished. No one was injured. Investigations revealed that after... 

The Guidelines for Process Equipment Reliability Data with Data Tables covers a variety of components used in the chemical process industry, including electrical equipment, analyzers, instrumentation and controls, detectors, heat exchangers, piping systems, rotating equipment (pump, compressor, and fan), valves, and fire protection systems. 

Probability of particular storage tanks or process vessels being hit by missiles caused by fires or explosions by fragmentation of rotating machines or pressure vessels, or transport accident s... 

Rumford decided to try a more controlled experiment. He placed a brass gun barrel in a wooden box containing about nineteen pounds of cold water, and used a team of horses to rotate a blunt steel borer inside the barrel. After 2.5 hours, the water boiled As Rumford described it, It would be difficult to describe the surprise and astonishment expressed on the countenances of the bystanders on seeing so large a quantity of cold water heated, and actually made to boil, without any fire. ... 

Linked characterized valves. The relationship between angular rotation of the valve spindle and open area of the valve can be adjusted over different portions of the flow range using a series of screws. In this way, the air/gas ratio can be characterized to any desired profile over the whole firing range. These valves are suited to fully modulating systems and are commonly used on steam boilers. 

Jean-Baptiste Biot (1774-1862) was born in Paris, France, and was educated there at the Ecole Polytechnique. In 1800. he was appointed professor of mathematical physics atthe College de France. His work on determining the optica rotation of naturally occurring molecules included an experiment on turpentine, which caught fire and nearly burned down the church building he was using for his experiments.
