Abstract: A B S T R A C T          Known Man-Piloted Hang Gliders and Kites use for their super-structure, three hollow tubings that are drilled and bolted in front to a nose plate and are referred to as the wing spars and the main keel spar. Another hollow tubing referred to as the crossbar is drilled and bolted to the main keel spar at a right angle and positioned at the center of gravity.          The crossbar is also drilled and bolted to the wing spars to keep them apart.        Because of this construction it is impossible to incorporate an angle of dihedral in this design, which would give it some lateral stabil-ity.  The sail used in known designs have no provisions for releasing excessive air pressure from below the sail. In this invention the main structural tubings are of sandwich type construction and have another light tubing about half the size of the outer one within them.  All air spaces are filled out with a noncorrosive stabil-izing foam, type RH 197. The cross tubing is removed in this invention and is replaced by two compression struts which take the function of the cross tubing in a more desirable way.  The compression struts are attached to the main keel spar end-fitting and wing spar fittings respectively. A flanged steel clamp centered at the center of gravity location on the main keel spar accepts the upper ends of the control-frame, which carries the pilots weight and provides attachment for the lower rigging cables.  The main keel spar in this invention does not have to be drilled at the center of gravity location and the load is spread over the width of the clamp. The sail in this invention has one vent-hole on each side of the keel spar, located at the center of gravity location and manually-operated flaps can release excessive air pressure fron below the sail in flight if so desired.  The amount of released air pressure is adjustable and is limited only by the vent-hole openings.  These vents also provide a stabilizing effect like the vent-hole does in a parachute.

Title: Method for controlling flue/gas combustion during the operation of a closed arc-reduction furnace, and an apparatus for the execution of the said method

Abstract: ABSTRACT OF THE DISCLOSURE           A closed arc-reduction furnace is enclosed by a flue-gas hood having electrode lead-ins, waste gas pipes and charging devi-ces.  Combustion air is blown through nozzles into the lower zone of the chamber above the burden and a cool inert or oxygen-poor gas is blown in to the uppermost part of the gas chamber in a flat cooling flow washing over the ceiling of the hood.  This reduces the volume of combustion air required and hence reduces the size of waste gas cleaner unit which is needed.  It also more effectively cools the flue gas hood and permits a lower and lighter hood to be employed.

Abstract: ABSTRACT OF DISCLOSURE               This disclosure teaches a movable sleeve connector for use in a method for replacing an existing utility pole (usually wood), without disturbing hardware mounted thereon.  As taught in United States patent 3,911,548, the utility pole includes a proximal section having a bottom end attached to the earth and a distal section having hard-ware mounted thereon.  The distal section (with its hardware intact thereon) is severed from the proximal section.  A new pole section (preferably of prestressed concrete) is attached to the earth appropriately located and adapted for receiving the distal section in axial abutting seating thereon whereby a joint is defined therebetween.  The distal section then is moved to sit coaxially on the new pole section and is engaged to the new pole section by means of a movable sleeve which is annular and engageable about outsides respectively of the new pole section and the distal section.          The sleeve is movable between an inoperative position (wherein it is displaced from the joint and an operative position (wherein it spans the joint).  The sleeve may be attached to both the distal section and to the new pole section by known means such as screws, bolts, grout or the like.  The joint is sealed by means of a suitable sealant, such as the grout.

Abstract: Process for the preparation of polyamines Abstract of the Disclosure This invention relates to a new and improved process for the preparation of polyamines based on diphenylmethane by acid condensation of aromatic amines with formaldehyde followed by processing of the condensation mixture.  Compared with similar processes known in the art, the process according to the invention combines the advantage of requiring less dis-tillation for processing the reaction mixture with the advan-tage of a wide scope for variation of the composition of the product finally obtained, particularly with regard to its concentration of 2,4'-isomers and greatly reduced concentration of 2,2'-isomers.  More particularly, the instant invention is directed to a process for the preparation of multinuclear aromatic polyamines by condensation of aromatic amines with formaldehyde in the presence of aqueous acid catalysts in a condensation reaction carried out in at least two stages, followed by neutralization of the catalyst and recovery of aromatic polyamines characterized in that free amine is re-moved from the condensation reaction mixture by means of a hydrophobic solvent after the first condensation stage and before the final condensation stage, and the amine thus removed is returned to the aqueous, catalyst-containing phase by re-turning the resulting amine-containing solvent phase to said aqueous phase before the first condensation stage.

Abstract: ABSTRACT OF THE DISCLOSURE :     A cathode for a chlor-alkali cell is made by providing a steel cathode with a dense, non-porous electroless coating of nickel.   Such a coating having a thickness of 1 to 15 microns is produced by immersing the steel cathode in a bath of suitable temperature, the bath containing a suitable nickel salt, water, a complexing agent and a reducing agent.   The cathode so coated hat a lower hydrogen overvoltage (by about 0.16 volt) than an uncoated steel cathode, and the effect persists through many months of use   The invention thus makes it possible to achieve considerable savings of power in the electrolysis of brine in a chlor-alkali cell.
