摘要:
A ``short form'' of McLeod gauge has been designed and built which is believed to be an improvement over the conventional constructions. These improvements consist of a simplified and compact construction of the compression chamber and mercury cistern, and of the entrance of the tubing connecting the gauge with the vacuum system directly through the top of the compression chamber.The actual construction is shown by a drawing and photograph.The theory of the McLeod gauge is briefly considered and the possible advantages of combining a controlled compression or expansion chamber with several existing gauges are indicated.

摘要:
The usefulness of a cathode ray oscillograph tube of the type of the Western Electric No. 224‐B is enhanced by any circuit that will provide a linear time axis. A number of methods of accomplishing this result have been described from time to time. One method used in the Bell Telephone Laboratories employs a hot‐cathode three‐element gas‐filled tube in the usual ``sweep'' circuit. This method possesses advantages in reproducibility, ease of control and synchronization. A brief description of the tube is given together with a simple analysis of the behavior of the circuit. Methods of coupling the sweep circuit to the oscillograph tube, of synchronizing the sweep frequency and of improving the linearity are discussed. A complete portable laboratory oscillograph outfit is shown as an illustration of one form that the device may assume. This set is for use within the audible frequency range.
