Abstract: ABSTRACT OF THE DISCLOSURE     The low-voltage winding of a line transformer consists of a foil winding.  In order to tune the line transformer to the third or the fifth harmonic, the coupling factor is adjusted by sliding the high-voltage winding with respect to the low-voltage winding.  The length of the leg of the core whereabout the low-voltage winding and the high-voltage winding are arranged substantially exceeds thewidth of the low-voltage winding.  The high-voltage winding can be partly slid off the low-voltage winding, with the result that the coupling factor is reduced.

Abstract: METHOD AND APPARATUS FOR INDUCTIVELY HEATING ELONGATED            WORKPIECES (Abstract of Disclosure) There is provided a method and apparatus for in-ductively heating elongated workpieces having a central axis and mounted in workpiece receiving stations of an indexable turret. A single shot inductor located within the path generally followed by the indexing workpieces is used to heat the workpieces.  One of the turret stations, when empty, is indexed passed the single shot inductor in a first direction and is loaded with a workpiece.  Thereafter, the loaded station is indexed in a second direction into the heating position with the workpiece located in the single shot inductor.  Thereafter, the workpiece is indexed from the single shot inductor for subsequent processing on the turret.

Abstract: ABSTRACT OF THE DISCLOSURE         A resurfaceable rotary die counter is prepared by employing a cylindrical counter core having a central, circumferentially extending relieved area filled with readily replaceable synthetic resin material containing pre-tensioned, spirally wound glass fiber roving which renders the resin craze and crack resistance even under extended continuous we.  Economical counter production is possible because of preparation of the counter on the press during makeready using the die as a counter forming element.  The resin is run in against the die prior to hardening of the same to form a reverse design surface in the counter which exactly mates with the doe surfaces.  A viscous resin having a minimum viscosity of about 6000 cps. is employed which has the characteristics of remaining on the counter core without substantial flow until ultraviolet cure can be effected. Fiber glass roving spirally wound under tension around the resin backed core during application of successive resin layers thereto provides a ten fold increase in strength over previously available systems.

Abstract: ABSTRACT OF THE DISCLOSURE             A process for separating hydrocarbon gases is described for the recovery of gases such as ethane and heavier hydrocarbons from natural gas streams or similar refinery or process streams. In the process described, the gas to be separated is cooled at a high pressure to produce partial condensation. The liquid from the partial condensation is further cooled and then expanded to a lower pressure. At the lower pressure, the liquid is then separated into fractions in a distillation column. The basic separation process is improved by combining the condensed high-pressure liquid with a stream having a lower bubble point, with cooling of one or both streams prior to expansion.

Abstract: STABILIZED LOCKING MECHANISM FOR THREADED TUNING SCREWS IN WAVEGUIDES                   by David D. Owlett ABSTRACT OF DISCLOSURE         A threaded invar tuning screw extending through the threaded aperture of an invar bushing in the broad wall of a waveguide filter presents a capacitance inside the waveguide.  This capacitance is varied by changing the depth of the screw in the waveguide in order to tune the filter.  A brass locknut on the screw has a truncated, conically shaped bottom that mates with a similarly shaped countersunk hole on the bushing, the conical bottom, countersunk hole, and screw being coaxial.  The mating surfaces on the nut and the countersunk hole reduce lateral movement of the screw during tuning and fixing of the position of the latter by tightening the locknut against the bushing.

Abstract: A B S T R A C T    A system for correcting misalignment and divergence in a long, propagating beam of radiation as is typically applied through a plurality of chambers to produce isotopically selective photoexcitation in a system for isotope separation.          The corrective apparatus comprises a reflective relay system placed at predetermined intervals along the path of propagation of the radiation where correction of alignment and/or divergence are required.  The reflective relay includes a concave mirror employed to correct divergence and which receives radiation directed at it by a first plane reflective surface which in turn responds to the radiation on the path of propagation.  The concave mirror reflects toward a second plane mirror which in turn reflects the radiation back onto the path of beam propagation with correction of alignment and divergence.  The first and second plane reflecting surfaces are adjustable on both tilt and position to permit alignment correction in both angle and displacement of the progating beam of radiation.

Abstract: TRANSMITTING LOOP ARRANGEMENT FOR RAILROAD CAB SIGNAL AND SPEED CONTROL SYSTEM                ABSTRACT OF THE DISCLOSURE A wire loop for carrying cab signal or speed control commands is laid parallel to the rails along the track center line except at the exit end of each section where an offset portion of this loop is laid immediately adjacent one rail to form a cut-in signal source.  A second loop is laid along the center line of the rails through this offset distance, which is equal to the stopping distance of the train from the restricted speed rate, and each loop is supplied by the same cab signal transmitter. Each train carries receiver coils positioned above the center line loops and above the cut-in loop positions. The normal cab signal or speed control apparatus is controlled by the signal picked up by the receiver coil above the center-line loops in the track.  A separate cut-in receiver is controlled by signals picked up from the offset portion of the main loop but responds only to a proceed signal command. Interruption of signal transmission to the second loop when the advance track section is occupied halts a train moving in the approach section and cuts off the cab signal apparatus by interrupting a stick circuit of a cab signal control relay. When the cut-in receiver again responds to a proceed signal command, transmitted after the advance track section is again unoccupied, it energizes a cut-in relay which picks up the cab signal relay to again complete its stick circuit and activate the normal cab signal apparatus.
