Abstract: Abstract Of The Disclosure For producing metallic castings an upright crucible is provided, the crucible having a compressible lining made from mineral wool and a bottom sprue opening into a mould supported within a casting box.  A high frequency heating coil surrounding the crucible serves to heat up and melt a solid metallic charge so placed within the crucible that an initial gap is left between the lining and the charge, the heating coil being so designed as to effect a progressive melting of the charge from the top down such that the initially melted upper part of the charge flows downwardly through the gap and re-freezes in the lower part of the crucible so as to prevent premeture discharge of any of the metal through the sprue until the entire volume of the charge has reached its molten state and attains a temperature higher than the melting temperature whereupon the entire charge is then quickly discharged through the sprue into the mould.

Abstract: ABSTRACT OF THE DISCLOSURE Apparatus for digitally controlling a thyristor includes a pulse frequency modulator having a resettable inte-grator that is coupled to an alternating current power source which supplies the thyristor.  A predetermined number of inte-grated signals are produced by the integrator in response to each half-cycle of the alternating current waveform.  The integrated signals are processed by a comparator circuit relative to a ref-erence voltage to produce a corresponding pulse train output having an inverse-cosine time separation between pulses.  Means are provided to synchronize the pulse train with the power source by introducing compensating changes in the reference voltage that correspond to the time difference between the end of each positive half-cycle of the alternating current waveform and the time taken to generate the predetermined number of pulses.  A counter pro-duces a binary output signal corresponding to the pulse train which is compared with input data from a digital computer.  A digital comparator generates a signal to enable a gate that couples the pulse train to a thyristor control input when the binary output signal and the computer data are in numerical coincidence.

Abstract: ABSTRACT OF THE DISCLOSURE:           A pneumatic tire having polyurethane in the surface exposed at the sidewall is coated with a colored polyurethane elastomeric coating by (1) applying to the sidewall surface a colored coating composition comprising a dye and/or pigment, an elastomeric NCO-terminated polyurethane prepolymer and a curing agent therefor, wherein the prepolymer is formed from a substantially satured hydroxy-terminated diol having a molecular weight of 500 to 10,000 or higher and a substantially saturated aliphatic diisocyanate, the mol ratio of the diisocyanate to the diol being 1.2:1 to 2.2:1, the prepolymer having a molecular weight over 2,500 when a blocked diamine is used as curing agent, and (2) heating the coated surface to cause the NCO-terminated polyurethane prepolymer to react with free -OH and -NH in the surface of the tire.  The resulting coating adheres so firmly to the sidewall surface that when the tire mounted on a rim and inflated to 24 psi, is tested against a flat large wheel surface at 50 mph., and the pressure of the tire against the wheel is increased to 200 percent of the rated load, as the test is run until the tire fails, the coating remains in place and does not crack.
