slide-wire

A slide-wire resistance is indicated by J, and _r_ is the resistance for the zero adjustment.

The slide-wire J is calibrated so that any inequalities in the temperature coefficient of the thermometer wires are equalized and also so that any unit-length on the slide-wire taken at any point along the temperature scale represents a resistance equal to the resistance change in the thermometer for that particular change in temperature.

The bar is in contact with the slide-wire J and therefore varies the position of the point _q_ and it also carries with it a stylographic pen.

A rise in temperature of T_ {2} gives an increase of resistance in the circuit and the sliding contact _q_ moves along the slide-wire toward J maximum until a balance is obtained.

The resistance S '' and S_ {1} are combined in a slide-wire resistance-box and are used to change the value of the whole apparatus when there are marked changes in the position of the thermometric scale.

If T_ {1} and T_ {2} are exactly of the same temperature, _i.e. _, if the temperature difference of the ingoing and outcoming water is zero, the sliding contact _q_ stands at 0 on the slide-wire and thus the resistance of the system from

The astronauts spent time Tuesday learning how to evacuate pad 39A if an emergency arises, including procedures to operate the slide-wire baskets that would quickly whisk the crew from the launch tower to a bunker west of the pad, and earlier Monday afternoon they test-drove an armored tank available for the astronauts to escape the area.

The crew will egress the shuttle and practice scurrying to the slide-wire baskets.
