Throttle Attachment

When you assemble the parts, lubricate the bolt between the two flat washers so the bearing surface can move freely. Adjust the bearing tension of the two flat washers with the first nut so the arm moves easily without wobbling, and lock it with the second nut. 

Through the saw handle, drill and tap a 4-in, thread (3) and mount the attachment (4) by screwing the bolt into the hole and locking it with a nut and washer. I ll explain how to use the remote throttle attachment on p.94.

In lumbermaking, you normally have to push the mill and roaring chainsaw through a cut, breathing exhaust fumes and spitting out sawdust all the while. But with my setup (1), you can stand back from the noise and vibration, and move the saw through the cut with minimum labor—all you have to do is crank a winch handle. Besides the winch, you ll need a remote throttle attachment for your saw, winch buttons to hold the winching ropes and a winch yoke. I ll discuss each of these in turn. 

The winching rope is attached at one end to the mill (p.42) and at the other end to the middle of a length of rope I call the bridle rope. One end of the bridle rope goes to the remote throttle attachment the other end must attach to the saw. But since there s no place on the saw to accept a rope, you have to make a holding button. I call this the bridle button. 

Start the engine with the throttle locked in the starting position. This half-open setting is adequate for edging most lumber. Or you can use the remote throttle attachment used in winch-milling. 

The interface with the process at the other end of the control loop is made by the final control element. In a vast majority of chemical engineering processes the final control element is an automatic control valve which throttles the flow of a manipulated variable. Most control valves consist of a plug on the end of a stem that opens or closes an orifice opening as the stem is raised or lowered. As sketched in Fig. 7.5, the stem is attached to a diaphragm that is driven by changing air pressure above the diaphragm. The force of the air pressure is opposed by a spring. 

It weighs 100 lbs and is designed to carry one person. Thrust is generated by self-starting, throttle controlled liq fuel rockets mounted in the tips of the two small rotor blades. The rotor is attached to, a steel. tube which curves downward to support the fuel tanks, a pilot seat and a cargo hook. A tube extending backward from the rotor hub carries a small rudder, and another extending forward and down is the pilot s control column... 

Thermal Conductivity. Conductivity measurements were made of tape candidates to determine whether or not they would satisfy the cable design requirements listed in Table I. The measurements were made for BNL by Jelinek of BCL using the apparatus illustrated in Fig. 7. The method was a modified steady-state conductivity technique where a temperature gradient was established between two copper plates separated by four layers of polymeric film. (Multilayer measurements were always made to approximate the series interfacial resistivity that would be present in lapped cable configurations.) One plate was attached to a controlled heat sink and a measured quantity of heat was added to the other plate by means of an electric heater. With the use of a liquid helium throttling dewar, the ambient temperature could be controlled to within 1 K. (Complete details of the conductivity measurement method are included in Appendix II of this paper.)... 

Mechanical design of the turbine blade root and rotor steeple attachments uses optimized contour to significantly reduce operational stresses. Steam flow to the high-pressure turbine is controlled by two floor-mounted steam chests. Each contains two throttle/stop valve assemblies, and two load-governing valves. 

Since the cryostat is constructed to withstand negative pressures, temperatures below 4 K could in principle be obtained by reducing the pressure over liquid helium in the container with a suitable mechanical vacuum pump and a throttling valve attached to the vent tube. The presently existing cryostat has not been used in this way as yet, however. 

High-pressure photocatalytic reaction studies can be undertaken by incorporating a sapphire window into the reaction cell. This allows the sample to be illuminated by an external light source (U V or visible), when the sapphire window is aligned with another window in the UHV chamber. Product gases may be detected and analyzed by the use of a gas chromatograph attached to the sample loop, By the use of suitable chromatographic columns and detectors (such as flame ionization, thermal conductivity, or photoionization), most likely product combinations may be separated and analyzed. Moreover, a more direct analysis can be made if the product stream is throttled (by means of a leak valve) into a separately pumped mass spectrometer. 

Attach a second clamp to the solvent and gas control throttle. Ensure that the trigger is clamped down and that solvent is flowing.
