摘要:
An instrument similar in principle to one developed by Kohaut but suitable for absolute measurements of large and inhomogeneous fields is described which consists essentially of a d.c. generator with a very small armature coil on the end of a long shaft driven by a synchronous motor, the induced voltage being a direct measure of the field. Typical results are given and the accuracy, relative and absolute, attainable discussed.

摘要:
An analysis is given of the controlling action of a vacuum tube in circuits similar to those proposed by Neher and Harper and Neher and Pickering. A modification of the latter's circuit eliminating some of its disadvantages is described. This circuit has been incorporated into a four tube network which controls the counter, scales down the impulse rate by any desired factor, and records the scaled counts. A new circuit is also described for recording the impulses from a single counter or from counters connected in coincidence.

摘要:
A simple apparatus is described for the determination of phases and the investigation of sluggish phase transformations in ferromagnetic alloys by means of magnetic measurements made at elevated temperatures. The force exerted on a small sample is measured when it is suspended in a furnace held between the poles of an electromagnet which produce a magnetic field of uniform gradient. A few measurements on stainless steel are included.
