Title: Method of producing grain-oriented electrical steel
Inventor: ALWORTH HARVEY MACK
IPC: C22C38/02
Filed: 1962-05-22
Abstract: Silicon-containing (2.75-3.5%) electrical steel is treated by first taking carbon on to solution at 1450-1750  DEG F., as by finishing hot rolling in that range, and then quenching rapidly to below 1000 DEG C.  The steel is then held in the range 600-900  DEG F. to allow lenticular precipitates of carbide to develop, and is then alternately cold-rolled and annealed to final size.  The initial carbon content may be 0.01-0.085%, but those steels having carbon content greater than 0.065% must be decarburized to below that level during a first continuous anneal following a cold reduction stage. All steels are then decarburized to below 0.003% during a second continuous anneal after rolling to final size. Decarburization may be effected at 1475  DEG F. in a nitrogen-hydrogen atmosphere having a dewpoint of 70  DEG F.

Abstract: 501,251. Directive wireless systems. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE. July 8, 1938, No. 20307. Convention date, July 8, 1937. [Class 40 (v)] In a direction-finder of the homing type operated by impulse signals in which stationary images of the received impulses are produced on an oscillograph, the pick-up from the directional or non-directional aerial is alternately reversed by applying it in parallel to two valves, the grids of which are also fed in pushpull, by the oscillograph time-base deflection voltage whereby synchronism between the pick-up reversal and the oscillograph sweep is automatically obtained. In Fig. 3, the pickup from the aerial, the connections of which are to be reversed, is applied through the tuned circuit F and coupling condensers D in parallel top the grids of the valves VI, V2 which are alternately rendered conductive by applying the time-base deflecting voltage to the grids in push-pull through the transformer U1. Since only the central part of the oscillograph screen is used for the observation of impulses, the time-base voltage wave-form may be as in Fig. 2, which gives a high deflection speed in the middle of the screen, thus widening the impulse images. In this case, the transformer U1 may be such as to pass only the sinusoidal component of the voltage wave. The reversing voltage may be synchronized with respect to the signal impulses in any known manner.
