That was a classic indicator in a questionable suicide.
The " slack indicator " of Messrs Siemens Brothers & Co.
The indicator was connected with a Ruhmkorff coil or other equivalent apparatus, designed to cause a continual succession of sparks to pass between the indicator and a metal plate situated beneath it and having a plane surface parallel to its line of motion.
The receiving arrangements comprised also an open or antenna circuit connected directly with a closed condenser-inductance circuit, but in place of the spark gap in the transmitter an electrolytic receiver was inserted, having in connexion with it as indicator a voltaic cell and telephone.
This helix is presented or held near to the antenna, and the length of it shortened until oscillations of the greatest intensity are produced in the helix as indicated by the use of an indicator of fluorescent paper.
The form of the torque curve, or crank effort curve, as it is sometimes called, is discussed in the article Steam Engine, and the torque curve corresponding to actual indicator diagrams taken from an express passenger engine travelling at a speed of 65 m.
Indicator diagram corresponding to 1 lb.
The crane is associated with her as an indicator of the weather.
In neutral, and still more in acid solutions, the dissociation of the indicator is practically nothing, and the liquid is colourless.
- The most important and most useful of the relations between the thermodynamical properties of a substance may be very simply deduced from a consideration of the indicator diagram by a geometrical method, which is in many respects more instructive than the analytical method generally employed.
This is geometrically obvious from the form of the area representing the function on the indicator diagram, and also follows directly from the first law.
Maximum speed controllers in connexion with the winding indicator, which do not allow the engine to exceed a fixed rate of speed, are also used in some cases, with recording indicators.
1897-1898, p. 132) the change in form of the spring is shown on a fixed indicator, which may be placed in any convenient position.
These theorems may prove useful in preliminary calculations where the pressure-curve is nearly straight; but, in the absence of any observable law, the area of the pressure-curve must be read off by a planimeter, or calculated by Simpson's rule, as an indicator diagram.
The theoretical indicator diagram is made up of two isothermal lines for the taking in and rejection of heat, and two lines of constant volume for the two passages through the regenerator.
Watts indicator-diagram, by the area cut off by the ordinates x = x0, x = Xi.
With sodium nitrite it forms a water-soluble blue dye, which is turned red by acids, and is used as an indicator, under the name of lacmoid (M.
The watch has on the back cover a flat gold indicator which can be pushed freely around from left to right until, by means of a pin inside the case, it locks with the hour hand and takes a corresponding position.
The point of this gold indicator bends over the edge of the case, round which are set eleven raised points--the stem forms the twelfth.
