摘要:
A partially open fired heater regenerative cycle wherein the fired industrial type heater cycle's heat transfer fluid replaces the air predominant nitrogen heat transfer fluid employed in a conventional air/fuel combustion heater. The heater cycle's method and apparatus means is susceptible to providing a 95 to 98 percent mass flow reduction of fugitive nitrogen oxide and carbon monoxide mass flow emissions as emitted by current art Low-NO.sub.x art heaters on a rated per million Btu per hour basis, and is further susceptible to developing steady-state heat transfer thermal efficiencies exceeding 124 percent.

摘要:
An apparatus to visually check coolant corrosiveness having first and second opposing ends in spaced apart relation to each other, and a sidewall extending substantially unbroken therebetween to define a hollow body; a non corrodible coolant barrier at said first end occluding said first end and forming a water tight seal over said first end; said non corrodible barrier having a transparency in at least a portion of said barrier; a corrodible coolant barrier at said second end occluding said second end and forming a water tight seal over said second end; whereby changes in coolant pH render the coolant corrosive, which corrodes the coolant corrodible barrier, thereby allowing coolant into said hollow body to be seen through said transparency in said first end.
摘要:
An automated drill road loader particularly suited for thin walled drill rods. The loader, generally affixed to a drill, includes an open frame sufficiently wide to accommodate and store drill rods. A clamp rod gripper and a swing gripper consisting of two pendulums are affixed to a side of the frame. A lift first raises a stored rod from the open frame. The rod is then grasped by the clamp rod gripper and the swing gripper to index the rod in a drill mast. By sequentially manipulating and translating the clamp rod gripper and the swing gripper, the rod is carefully held for threading. The drill rod may be establishing a new drill string or it may be inserted into an existing drill string.
摘要:
A diffusional gas transfer system and method having a membrane disposed between a first gas domain and a second gas domain. The first gas domain includes a first mechanism for directing a first environmental gas flow transversely over and in contact with a first surface of the membrane. The second gas domain includes a second mechanism for directing a second environmental gas flow transversely over and in contact with a second surface of the membrane. The membrane is a diffusional gas transfer medium having a multiplicity of tortuous pathways extending from the first surface of the membrane to the second surface of the membrane. The void volume fraction of the membrane is at least 0.2. The membrane is capable of substantially blocking the transfer of particles from the first gas domain to the second gas domain, while permitting the diffusion of gases between the first and second gas domains, and the first gas domain is maintained at a pressure higher than the second gas domain.
摘要:
A system for locating inflamed plaque in an artery of a patient includes a catheter with an expander mounted at a catheter distal end. An infrared carrier, e.g., an optical fiber is mounted on the catheter with a carrier distal end attached to the expander. A sensor is connected to a carrier proximal end to measure infrared radiation transmitted through the carrier from the carrier distal end. In use, the expander is operable to selectively move the carrier distal end into contact with the arterial wall. Infrared radiation can then be measured to determine the temperature at the arterial wall. Temperatures at various locations can be taken, with elevated temperatures being indicative of inflamed plaque.
摘要:
A projected display sport goggle that is used to provide continuous and uninterrupted feedback of information to the athlete. The goggle will permit the athlete to adjust their performance based on real time information. This information includes speed, distance traveled, temperature, heart rate, time of day, elapsed time, cadence, and a time based alarm. The informational display presented by the goggle is easy to read and understand. Similar in size and shape to a pair of eyeglasses, it will not significantly interfere with or restrict the movement of the athlete. It is capable of withstanding the impacts and shocks associated with athletic activities. It is easy to use and operate, and is inexpensive to manufacture. The goggle provides a safe, economic, and highly reliable method for monitoring an athlete's performance.
