Abstract: Abstract of the Disclosure This invention relates to austenitic alloys of iron, chromium, aluminum, and yttrium used as cladding suitable for high temperature applications in corrosive gas turbine atmospheres.   These alloys are normally ferritic in nature, but they are rendered sustenitic in accord with this invention.   This is accomplished by adding to the alloys selected quantities of nickel or nickel and cobalt, at least 30% by weight.   The addition of these elements yields a 66% or greater face centred cubic crystal structure having high temperature properties which are superior to the base alloys without diminishing the excellent high-temperature oxidation and hot corrosion resistance of the base alloys.

Abstract: ABSTRACT           Protease enzyme impurities contained in bacterial .alpha.-amylase enzyme preparations are inactivated by a mild heat treat-ment in the presence of a protective material.  Useful protective materials include calcium and starch hydrolysates such as corn syrup. The protease-free .alpha.-amylase can then be used to solubilize starch materials by various granular starch and conventional processes. Hydrolysates obtained contain significantly less soluble protein than those prepared using untreated .alpha.-amylases.  A preferred .alpha.-amylase enzyme preparation is one derived from a bacillus licheniformis microorganism.

Abstract: ABSTRACT         The disclosed spark source is adapted to generate elec-trical sparks to produce light for spectroscopic analysis of materials placed on the spark gap electrodes or introduced into the sparks.  The disclosed spark source comprises a high voltage transformer having a secondary winding for supplying alternating current at a high voltage, a storage capacitor, a charging circuit including a rectifier connected between the secondary winding and the capacitor for charging the capacitor, spark gap electrodes having a spark gap therebetween, a discharge circuit including an electronic switching device connected between the capacitor and the spark gap electrodes for discharging the capacitor across the spark gap and control means for supplying a sequence of variably spaced triggering pulses to the input means of the electronic switching device for producing a sequence of spark cycles in which the capacitor is charged to substantially the same voltage for all of the spark cycles.    During the intervals between sparks, the capacitor is re-charged by the transformer and the rectifier.  The timing of the sparks is varied, with reference to the phase angle of the alternating current, so that the capacitor is charged to the same voltage during each of the intervals between sparks.          The timing of the sparks is computed to accommodate the variation in the instantaneous voltage developed by the trans-former during such intervals.  By varying the timing of the sparks, it is possible to vary the voltage to which the capacitor is charged, over a wide range.  The electronic switching device may comprise a thyratron in parallel with a shunting diode, to carry the oppositely polarized half-cycles of the oscillatory capacitor discharge current.  An inductance element may he connected in series with the thyratron to improve the commutation between the thyratron and the shunting diode.  It is also advantageous to insert an inductance element in series with the shunting diode to bring about a further improvement in such commutation.

Abstract: ABSTRACT       A plurality of elongated hollow, circular, foraminous substantially vertical tubes contiguously stacked transversely to the direction flowing liquid such as waste water containing foreign matter, i.e., settable solids and free oil, in a coalescer-separator apparatus provide a filter body providing for significant surface area contact by the liquid on both inside and outside sur-faces of the tubes to entrap the foreign matter but defining substantially vertical passages permitting the entrapped foreign matter to be gravity separated with the lighter matter coalescing and floating upwardly and the heavier matter settling downwardly so that substantially clarified effluent flows from the apparatus.          The stacked tube filter body is contained within an insulated closed container of a sufficient capacity, and the arrays of holes in the tube walls are coordinated with respect to the intended volumetric capacity of the apparatus, so that turbulence in the liquid flowing through the filter body is minimized.

Abstract: ENGINE TIMING CONTROL CIRCUIT ABSTRACT OF THE DISCLOSURE          A pick-up provides a square wave signal whose period corresponds to 720°/N where N is the number of engine cylinders for a four stroke, two cycle internal combustion engine.  An integrator is reset by both positive-going and negative-going edges of said square wave signal to produce a sawtooth waveform having a period equal to 360°/N.  A blanking circuit which is coupled with the pick-up blanks the sawtooth waveform of said integrator during said alternate half cycles of the square wave.  The blanked sawtooth waveform is supplied to one input of a comparator and a desired timing signal to the other input of said comparator.  The comparator provides an engine timing signal when a predetermined relationship between the blanked sawtooth signal and the desired timing signal is attained.  In this way, the engine timing signal is given once per cycle of said blanked sawtooth waveform with the timing thereof relative to said square wave being determined by the desired timing signal The preferred embodiment discloses a four cylinder engine con-figuration with electronic spark timing control.

In use, two such devices are disposed on opposite sides of the strip and any impingement of the opposed jets upon each other at or beyond the strip edges is detected by noise level detectors.  The baffles can then be moved to minimise the degree of impingement and thereby reduce the noise level resulting from impingement.

Abstract: ABSTRACT OF THE DISCLOSURE     A shoe having a sole, an upper formed from a relatively soft and extensible material, a lacing strip and a bandage connecting the lacing strip with the sole.          The bandage is formed from a material which is less ex-tensible than the material of the upper,  The bandage includes an elongated portion and a connecting portion which extends laterally of the elongated portion at the juncture of the bandage with the lacing strip.  The la-terally-extensive connecting portion transmits forces from the lacing strip to the elongated portion, and substantially prevents transmission of such forces through the extensible material of the upper.  Thus, the upper is less apt to become fatigued or distorted during wear.          This abstract should not be taken as a complete exposi-tion of the present invention.

Abstract: PHN. 9187.     ABSTRACT:                Capless electric incandescent lamp having a flat pinch with a first major face along which the current conductors are bent back may be constructed so that when placed in a lamp holder the filament always assumes the same position.  For that purpose the lamps comprise on a second major face means which can coop-erate with a fixing member in a lamp holder and two inclined side faces for centring the lamp in a lamp holder.  In a capless incandescent lamp according to the invention, grooves or ribs constituting the means to cooperate with a fixing member are situated on the inclined side faces of the pinch.  As a result of this construction, the lamps are more accurately positioned in a lamp holder in spite of smaller forces exerted by the fixing member.
