Safety thread

0 A recursive function should only acquire a mutex once, or a mutex supporting recursion must be used, o Pay attention to locking/unlocking order when using multiple mutexes.

There have been reports of unique and improper SRV discharge piping on threaded safety relief. If the SRV discharge line runs horizontally and has a 90-degree ell mounted to provide a counter-clockwise thrust, then the SRV has spun and unthreaded their way out the connecting nozzle. 

Remove end cap from pipe. Knot one end of smfe fuse. Thread safety fuse through hole in end cap so that knot...

Acetylene cylinders are fitted with safety devices to release the acetylene ia the event of fire. Cylinders manufactured ia the United States are equipped with safety devices which contain a fusible metal that melts at 100°C. In large cylinders the safety devices are ia the form of a replaceable, threaded steel plug with a core of fusible metal. Small cylinders (0.28 and 1.12 m 10 and 40 fT, respectively) may have the fusible metal ia passages ia the cylinder valve. 

Shipment and Storage. Sulfur dichloride, if kept dry, is noncorrosive at ambient temperatures, thus carbon steel and Hon can be used Hi the constmction of tanks, piping, and dmms. However, when water or humidity is present, materials resistant to hydrochloric acid must be used, eg, glass-lined pipe. Teflon, titanium, HasteUoy C, or possibly a chemically resistant, glass-reiaforced polyester. Threaded pipe joHits should be assembled with Teflon tape. Hoses should be constmcted with a Teflon inner lining with the outer tube constmcted of Neoprene or braided 316 stainless steel protected by an adequate thickness of Teflon. Sulfur dichloride should be stored away from heat and away from dHect rays of the sum. Toluene and sulfur dichloride react exothermically when catalyzed by Hon or ferric chloride. Safety precautions should be foUowed when such a mixture is present (165). 

The Matimum PuH is based upon the ultimate tensile strength in the pin thread area with a safety factor of three. 

Issue a safety bulletin to all other facilities to inspect the threads on filter pots of similar design. 

Transcoronary venous injection is performed with a catheter system threaded percutaneously into the coronary sinus. Initial studies in swine have confirmed the feasibility and safety of this approach [121]. This delivery method has also been used to deliver skeletal myoblasts to scarred myocardium in cardiomyopathy patients [120]. With intravascular ultrasound guidance, this approach allows the operator to extend a catheter and needle away from the pericardial space and coronary artery into the adjacent myocardium. To date, human feasibility studies have had a good safety profile. This technique is limited, however, by coronary venous tortuosity, lack of site specific targeting, and its own technically challenging nature. Unlike the transendocardial approach, in which cells are... 

Safety fuse A waterproof coated, thread-wrapped cord filled with black powder designed for initiating a nonelectric blasting cap. 

These are not to be confused with Bickford fuse or safety fuse manufactured by the same company, which consists of a central thread surrounded by a core of black powder enclosed within a tube of woven threads, surrounded by various layers of textile, waterproof material, sheathing, etc. This is miner s fuse, and is everywhere known as Bickford fuse after the Englishman who invented the machine by which such fuse was first woven. The most common variety bums with a velocity of about 1 foot per minute. When the fire reaches its end, a spurt of flame about an inch long shoots out for igniting black powder or for firing a blasting cap.
