Abstract: RCA 75,262 Abstract A circuit is described for protecting a semiconductor junction device such as a transistor against damage from high voltage transients that can be produced by kinescope arcing in a television receiver.  The protected device is coupled to a circuit point at which the transients can appear.  The protection circuit comprises a normally nonconductive protection transistor with a collector coupled to a source of operating potential, a base coupled to a source of threshold conduction bias reference voltage, and an emitter connected to the circuit point at which high voltage transients are likely to appear.  The base bias of the protection transistor is determinable independent of the bias of the protected device, and the protection circuit is connected to the protected device with substantially zero voltage offset between the circuit point and the protected device. The protection transistor conducts in response to transient voltages appearing at the circuit point above a threshold level, and provides a path for safely diverting potentially destructive transient current away from the protected device.

Abstract: ABSTRACT OF THE DISCLOSURE           Railroad rails having improved wear resistance, are produced by controlled forced cooling from above the austenite transformation temperature, to produce rails having a fine pearlite metallurgical structure in the head portions of the rails.  Apparatus comprising a series of cooling headers utilizing a liquid cooling medium, such as unheated (i.e. cold, or ambient temperature) water, alternating with a series of air zones, is preferably arranged in line with the production rolling mill, to receive hot rails as they emerge from the mill, without the necessity of intervening reheating.  A roller type restraint system transports the rails through the cooling apparatus, while restraining them in the appropriate position.  Each segment of the rail length is intermittently subjected to forced cooling by spray application of the liquid cooling medium, applied to the head portion, and the central portion of the base bottom, of the rail, with means being provided to prevent spray from impinging on the web and base tips of the rail.  During the intervals between applications of forced cooling, heat soaks back from the web portion of the rail, the operating parameters of the system being so arranged that the temperature of the rail remains essentially above the martensite formation temperature.  A computerized control system discontinues the application of forced cooling, at a predetermined stop temperature, also above the martensite formation temperature.  The apparatus and method are capable of producing rails having the desired fine pearlite structure in the head portion, on a consistent basis, notwithstanding wide variations in temperature between different rails, and different segments of the same rail, as they emerge from a conventional production rolling mill.

Abstract: ABSTRACT OF THE DISCLOSURE           The invention is concerned with a method of detecting the level of a melt in a continuous-casting mold by means of a primary coil and at least three vertically spaced secondary coils surrounding the mold.  According to the invention, a primary magnetic field is formed with the primary coil, which extends horizontally through the mold into the melt generally at the melt level.  This primary field generates eddy currents in the melt that in turn generate secondary fields that induce in the secondary coils voltages that peak as the melt level comes level with the secondary coils.  Each of the induced voltages is combined with each of the other induced voltages to provide a plurality of output voltage curves each correspond-ing to the combined outputs of the respective two induced voltages and each peaking when the melt level lies at a respective location intermediate the respective induced voltages.  The melt level position relative to the coils is derived from these output voltage curves.
