 Engineers at Davisco Foods International Inc. wanted to incorporate mix-proof valves into their process controls for three new cheese vats at the company''s Jerome, Idaho, facility. Unfortunately, the PMOs did not recognize any block-and-bleed valves that could handle the cheese curds the system would have to deal with. Rockford, Ill.-based Sudmo North America Inc. accepted the company''s challenge to design a valve that could handle large particulate without clogging and then win regulatory approval chain saw for the design. work area: india.catleia oil co.(petrobras subsidiary)petrobras virig design: rg letourneau, inc.construction: davie shipbuilding ltd., canada, 1982.performance: water depth--230''; drilling saw depth--23,000''.quarters: 84 persons.hull: mcculloch 243'' x 200'' x 26''.variable parts load: 1,997 t.heliport: 70'' dia.storage: mud & cmt bulk--7,200; liquidmud--1,416 bbl; fuel--2,970 bbl; water fordrilling--6,657 bbl; potable water--2,760 bbl.drilling chain saw equipment: drawworks--oilwell e-3000;pumps--two oilwell a-1700-pt, triplex; 2. automatic slack adjusters (asa). a self adjusting slack adjuster is a ratchet wrench built into a manual saw slack adjuster. mcculloch the ratchet drive rotates slightly during either a brake application or during brake release depending parts upon the design. when brakes chain are in proper adjustment, the ratchet decouples. as the lining wears, saw or as the drum expands, the ratchet drive continue to adjust to combat the additional stroke length.there mcculloch are two design approaches parts to brake sensing. one method senses clearance or load sensing and adjusts at the early part of the brake application. the second method senses stroke and adjusts at the end of the brake release stroke. asas are mandatory on all new chain air-brake equipped tractors and trailers in the us.3. antilock braking systems. abs systems are designed to prevent tractor jackknifing or trailer sluing. electromagnetic sensors, mounted on wheel ends or inside the axles, sense wheel rotational speed. an electronic control saw unit (ecu) monitors the information from all the sensors and compares the wheel speeds. as the vehicle decelerates, mcculloch the ecu senses when any wheel is decelerating too parts rapidly, indicating that chain the wheel is approaching lockup. when this happens, the ecu sends a signal saw to solenoid valves that reduce air pressure in the brake chamber. when the wheel deceleration mcculloch rate changes, air pressure is restored. the sequence occurs in microseconds. end result is smooth stopping of semi-combination vehicles parts in a straight line. abs is now mandated on all new tractors and trailers built in the us.
