Abstract: SUPERSONIC BLADING     Abstract of the Disclosure Supersonic rotor blading in an axial-flow fan or compressor employs blades such that shock waves originating on a blade are canceled at the intersection of the wave and the surface of an adjacent blade by virtue of a blade configuration such that the shocks intersect the blade surface at a line of properly oriented change in flow angle of the blade surface.  A three-wave system is employed.

Abstract: ABSTRACT OF THE DISCLOSURE     The Specification describes Redox Accelerator Systems for use in the polymerisation of ethylenically unsaturated monomer compositions comprising, as the reducing component, the addition or condensation product of the reaction of an aliphatic or aromatic-aliphatic tertiary amine, at least one of the aliphatic or aromatic-aliphatic groups thereof being substituted by at least one hydroxyl group, with a ????, a compound containing a carbon-carbon double bond, a compound containing an epoxy group, an isocyanate or a carboxylic acid or acid chloride or anhydrite thereof.  The use of the above-described accelerator systems provides monomer compositions which have a relatively long pot life but which subsequently polymerise rapidly and completely.  The accelerator system are particularly useful for the polymerisation of monomer compositions containing an inorganic filler, e.g. for the production of road coverings etc.

Abstract: BETA-AMINO NITRILE CATALYSTS FOR       POLYURETHANE PREPARATION              ABSTRACT OF THE DISCLOSURE           Cellular urethane polymers essentially free of the strong, objectionable amine odor characteristic of N-ethylmorpholine, are provided by effecting the poly-urethane forming reaction in the presence of beta-tert-amino nitriles.  In view of their low residual odor and effectiveness in the catalysis of the water-isocyanate reaction, the beta-amino nitriles either alone or in combination with other tertiary amines, are used with particular advantage as direct replacements for N-ethyl-morpholine in the manufacture of water-blown flexible polyurethanes, both molded and free-rise, including high-resilience foam as well as foams stabilized with either organosilicone or silicon-free organic surfactants.          Especially effective for the formation of flexible poly-ester foam stabilized with either type of surfactant are blends of the beta-amino nitrile catalyst such as, in particular, 3-(N,N-dimethylamino)propionitrile, with dimethylethanolamine or a bis[2-(N,N-dimethylamino)alkyl]-ether.

Abstract: ABSTRACT OF THE DISCLOSURE    A mercury vapor electric discharge lamp is supplied with AC electric power, which is variable over a wide range, to control the lamp output power in the form of the intensity of the electromagnetic radiation emitted over a correspondingly wide range of from approximately 5% to 100% or better of rated output power without lamp extinction. An AC phase modulation control circuit controls the AC electric power supplied to the lamp such that applied voltage remains relatively constant while the current is controllably varied determined by the phase angle of conduction in the control circuit.  Control of the AC phase modulation control circuit is effected in response to the actual output power of the electromagnetic radiation emitted by the lamp, the speed of a printing press or conveyor line with which the lamp may be used to cure ultraviolet sensitive inks, paints, plastics and the like on some form of substrate.  Moreover, the actual lamp intensity, when below a called for intensity, may be used to control the speed of the press conveyor, process line and the like.  Means also are disclosed to indicate, for example, lamp aging, press or process slow down and the like, and a lamp cooling blower is automatically controlled to vary the amount of colling proportional to lamp output power.

Abstract: ABSTRACT OF THE DISCLOSURE   An indicator mechanism for an apparatus for correcting the existing grade and horizontal alignment of railroad track in accordance with a wire reference system.  The mechanism includes frame means, the position of which in use is referenced to the existing position of an adjacent section of the railroad track.  Pivot means are mounted for vertical, sliding movement on the frame means and a needle indicator is mounted on the pivot means to pivot about a horizontal axis generally parallel to the rails of the railroad track.  Scale means are arranged on the frame means near one end of the in-dictor to indicate in combination with the indicator the existing grade and horizontal alignment of the adjacent section with reference to the wire ref-erence system.  During use of the mechanism, the position of the indicator is adjusted by a reference wire of the system which contacts the indicator. Preferably, this reference wire extends through a relatively small hole in the bottom portion of the indicator.  The scale means comprises two separate scales, one scale to indicate the existing grade and the other scale to in-dicate the horizontal alignment of the adjacent section.     :
