Abstract: CONTINUOUS CASTING PROCESS AND APPARATUS                       ABSTRACT   In a continuous casting process the flow, of molten me-tal is continuously fed into a mould to be further submitt-ed to the action of the magnetic field generated by an ele-ctrical inductor and to that of a stabilizing coil so that a column of molten metal is formed. The column of molten metal is then cooled to produce a continuous strand or in-got. The current supplied to the stabilizing coil has its phase lagging behind that of the current in the inductor with the phase angle between them ranging from 95° to 165°; the amplitude of current in the stabilizing coil being 0.1 to 0.4 time the current amplitude in the inductor. Appara-tus for performing the above-described continuous casting process comprises a mould formed by an electromagnetic in-ductor and a stabilizing coil from a nonmagnetic material in the form of triangle arranged coaxially with the inductor and having its apex oriented inside the mould. The height of triangle in cross-section of the stabilizing coil and the greater side of the triangle are in the ratio ranging from 0.7 to 0.96.

Abstract: ABSTRACT OF THE DISCLOSURE         Disclosed herein is a secretin-containing composition which comprises, as an intimate mixture or a combination of separate units, secretin and one or more additives selected from the group consisting of lecithin, ethylene oxide-propylene oxide copolymers, hydroxypropylcellulose, methylcellulose, polyoxyehtylene hydrogenated castor oil, polyethylene glycol sorbitan oleate and methylcyclodextrin. Also disclosed is a method to prevent the adsorption of secretin by incorporating one or more of the above additives in a solution of secretin.  Use of such additives has been found to be very effective, even at very low concentration levels, in preventing secretin from being adsorbed on the walls of plastic- or glass-made syringe barrels, infusion bottles or dripping guide tubes, thereby permitting administration of secretin at accurage dosage levels.

Abstract: ABSTRACT OF THE DISCLOSURE          A catalyst trough containing multiple guide tubes in registry with the tubes of a multi-tube catalytic reactor is utilized to unload catalysts therefrom with maximum dust containment and maximum catalyst recovery. The catalyst recovery trough contains an outlet collar connected to an outlet line and a positive fastening means whereby the trough is fixedly but detachably connected to the tube sheet of the reactor.  The guide tubes extend vertically upwardly from the bottom of the trough and are open in the bottom so as to allow the provision of flexible steel rods or "fish tapes", which may or may not be equipped with high-fluid pres-sure tubes as air-lances for feeding into the tubes of the reactor, which are on center with the guide tubes of the trough.  In this manner any catalytic material which is struck or bridged across the catalytic tubes may be dislodged so as to fall by gravity into the recovery trough and into an outlet line for recovery.

Abstract: ABSTRACT OF THE DISCLOSURE        Several embodiments of wall covering are provided all of which are directed to providing an insulated wall covering including panels commonly called "siding".  The wall covering is attached, by starting at the bottom of the wall and working upwards and is intended to provide a continuous insulating covering and to resist rattling and separation caused by building shrinkage.  A starter strip or board is provided at the bottom of the covering to permit some movement to relieve compressive forces in the siding caused by building shrinkage.          These forces are either transmitted directly from one piece of insulation to an adjacent piece of insulation, via structure forming part of associated siding panels, or by use of separate load transfer strips.

Abstract: Abstract of the Disclosure There is described an ADPCM decoding circuit of the type which receives a coded signal outputted from an ADPCM encoder which adaptively quantizes at each sampling time a residual signal which is a difference between a signal formed by linearizing an input nonlinear encoded PCM signal, and a prediction signal adaptively predicted, and which delivers a nonlinear PCM decoded signal.  An adaptive inverse quantizer produces, from a quantized coded signal produced by the ADPCM encoder, a representative residual value signal, a lower limit residual signal and a higher limit residual in accordance with the residual signal on the side of the encoder, and which determines a quantizing characteristic at a next sampling time in accordance with the quantized code signal.  An adder adds an adaptive prediction signal to each of the representative residual value signal, the lower limit residual signal and the higher limit residual signal to produce a representative decoded value signal, a lower limit decoded value signal and a higher limit decoded value signal.  A nonlinear PCM converting circuit converts the representative decoded value signal into a nonlinear encoded PCM signal to form an output nonlinear PCM signal. A linear PCM converting circuit linearizes the output nonlinear PCM signal to produce an output linear PCM signal.  A comparator compares the output linear PCM signal with the lower limit decoded value signal and with the higher limit decoded value signal to form a nonlinear PCM decoded signal which corresponds to the output nonlinear PCM signal, the output nonlinear PCM signal added with +1 or the output nonlinear PCM signal added with -1.  An adaptive prediction circuit inputted with the representative decoded signal together with the representative residual value signal produces the adaptive prediction signal at a first sampling time and determines a prediction char-acteristic at a next sampling time.
