Ringfeder Power Transmission USA Corporation
Protect buildings by cushioning seismic vibrations in industrial facilities. RINGFEDER POWER TRANSMISSION is currently developing an innovative solution to absorb seismic vibrations which could affect the switchgears in electrical substations across the North American continent. Switchgears are usually firmly connected to the floor slab with bolts and nuts – a fact which can have fatal consequences in the event of a tremor. To counteract this scenario, a two-way cushioning element equipped with a long and a short spring has been mounted...

Columbia Research Labs, Inc.
Seismic and Low Frequency Motion Study Sensors Models SA-107LN, SA-207LN, and SA-307LN servo accelerometers from Columbia Research Labs are high sensitivity, ultra low noise sensors designed for use in seismic, and low level, low frequency motion studies. The SA-107LN is a single axis unit and the SA-207LN, and SA-307LN are two and three axis units. On all units, low noise electronics used in conjunction with the force balance principle make possible measurements in the low frequency micro-G range. Aside from the traditional DC-coupled zero...

Griffin Pump & Equipment, Inc.
Wellpoint Dewatering Method The wellpoint system is one of the most versatile of pre-drainage methods which can pump a few gallons per minute in fine sandy silts or many thousands of gallons per minute in coarse sands and gravels. A wellpoint system consists of a number of wellpoints spaced along a trench or around an excavation site, all connected to a common header, which is attached to one or more wellpoint pumps. Wellpoint systems are most suitable in shallow aquifers where the water level needs to be lowered no more... (read more)
Best grounding methods for shielded cable Grounding Methods Compared. To select the best grounding method for shielded cable installations, you have to strike a balance between installed cost and grounding performance. Yet that ’s easier said than done. Some of the most common grounding methods, while seemingly inexpensive in terms of the component cost, require labor-intensive installation procedures that can drive up installed cost significantly. Other methods lack the full 360 º contact... (read more)Browse Electrical Connectors Datasheets for Lapp USA
Spectral Methods - Estimation of Fatigue Life . There is also software available which is used to estimate the spectral moments of the power spectral density functions of the signal, the number of peaks per second and the number of upward zero crossings per second in the time series. Fatigue life is estimated, using the method of Dirlik with examples illustrating the use of the program. The spectral moments of the response of single degree of freedom systems to white noise are described and methods for their estimation are outlined. Other Items...
