Figure parts A–D show steps in forming a "short tie" Western Union splice. Figure parts E and F show two possible "long tie" variations. [2]The Western Union splice or lineman splice is a method of joining electrical cable, developed in the nineteenth century during the introduction of the telegraph and named for the Western Union telegraph company.
A standard measurement, hood static pressure, provides information on airflow changes that affect hood performance. For hoods designed to prevent exposure to hazardous airborne contaminants, the American Conference of Governmental Industrial Hygienists recommends the installation of a fixed hood static pressure gauge.

The gauges are locked by twisting the knurled end of the handles; this action is performed to exert a small amount of friction on the telescopic portions of the gauge (the smaller diameter rods found at the T head of the gauge). To use, the gauge is inserted at a slight angle to the bore and gently locked to a size slightly larger than the bore ...
The markings outside the active area help to align the gauge during installation. A strain gauge (also spelled strain gage) is a device used to measure strain on an object. Invented by Edward E. Simmons and Arthur C. Ruge in 1938, the most common type of strain gauge consists of an insulating flexible backing which supports a metallic foil ...
A short-term renter would most likely lose any investment made in improving the property unless a prior agreement were to be made with the property owner. Installation of a quality central vacuum increases the property value of a residence or commercial property. [12] [4] [10] [11]
There are also some extreme narrow gauge railways listed. See: Distinction between a ridable miniature railway and a minimum gauge railway for clarification. Model railway gauges are covered in rail transport modelling scales. Train with model Southern Railway Schools class. Triple-gauge pointwork (3 + 1 ⁄ 2 in, 5 in, and 7 + 1 ⁄ 4 in) on ...
Four-point measurement of resistance between voltage sense connections 2 and 3. Current is supplied via force connections 1 and 4. In electrical engineering, four-terminal sensing (4T sensing), 4-wire sensing, or 4-point probes method is an electrical impedance measuring technique that uses separate pairs of current-carrying and voltage-sensing electrodes to make more accurate measurements ...
Narrow Gauge and Shortline Gazette, subtitled Accurate Information for Fine Modelbuilding, is a magazine published bimonthly (every two months) in the United States. It was published by Benchmark Publications, Ltd. of Mountain View, California , until the title was acquired by White River Productions in 2017. [ 1 ]
