Abstract: ABSTRACT OF THE DISCLOSURE          In rotary fluid machines in which the conversion of pressure energy of fluids is obtained by the circulation of at least two spaced vane members in at least one spiral-like passage of revolution in the form of a channel or groove, the rotary fluid part containing the channel is manufactured by a vane tool simulating the configuration of the vane members to be circulated in the channel and the rotary fluid machine part containing the vane member is manufactured by a disc tool simulating the configuration of the channels within which the vane members circulate.  The method of manufacture employs a lathe machine combined with adapter mechanism permitting the vane or disc tools, as the case may be, to simulate the relative movement between the channelled part and the vane part in the rotary fluid machine.  Where the channelled part for the rotary fluid machine requires undercut portions, the vane tool is of a reduced size, but otherwise simulates the actual vane, and the manufacture is accomplished by varying the angular displacement of the tool to either side of a normal center position so as to encompass the extremities of the law of movement of the actual vane member in the rotary fluid machine.

Abstract: ABSTRACT     A method for repairing turbine vanes and the like which have become worn or cracked after extended periods of use.          The method involves refurbishing a metal alloy turbine part having a composition containing substantial quantities of cobalt, with silicon present in an amount essentially on the order of not more than several percent, and embraces the steps of mixing a preparation of an overlay metal alloy com-prising substantially the same respective amount of cobalt as contained in the turbine part and with silicon present in said alloy, in an amount essentially on the order of not more than several percent.  An amount of silicon on the order of substantially 10% to 15% of the original silicon content of the preparation is added to the latter, and the mixture of the preparation and added silicon is converted into a molten alloy and applied to the eroded surfaces of the airfoil of the part to build up the same beyond its original surface, after which the part is sintered in a furnace at a temper-ature above 2,000°F. During the said application, substan-tially all of the added silicon contained in the molten alloy mixture that was applied to the part is burned off, such that the resultant overlay alloy has substantially the same com-position as the turbine part.   Following removal of the part and cooling, the overlay surface of the airfoil of the part is ground down to restore the dimensions thereof substanti-ally to those of a new part.  The advantage of this method over prior procedures for  repairing turbine parts is that a complete restoration is possible, such that the repaired units can meet the rigid  specifications and requirements set forth for new components of this type, all at a greatly reduced cost.

Abstract: ABSTRACT OF THE DISCLOSURE     Vertical blinds having commonly housed and traversely movable controls for controlling the traverse and rotation of the vanes are disclosed.  In a disclosed embodiment, the vanes are supported by carrier members, and a rotation rod extends through the carrier members.  The carrier members are slideable along the rotation rod.  A control assembly is mounted to slide along and also rotate the rotation rod.  Sliding of the control assembly along the rotation rod slides the carrier members to thereby traverse the vanes, and actuation of the control assembly rotates the rotation rod and the vanes.  The control assembly includes meshing bevel gears, one of which is coupled to an actuating rod or wand and the other to the rotation rod whereby rotation of the wand causes rotation of the vanes.  The control assembly is slid by means of the wand which is universally connected to the control assembly.  The wand is thus a unitary control for actuating both traverse and rotation of the vanes.

Abstract: ABSTRACT        The invention is concerned with paints which will intumesce as a result of thermal decomposition to a carbon-aceous residue in the presence of an expanding agent liberating an incombustible gas, the formation of the carbonaceous residue being promoted by a dehydrating agent typically a phosphoric acid source.  The novel paint is essentially characterised by the use of certain water-insoluble nitrogen-containing compounds fulfilling the dual role of carbon source and intumescing agent.  These nitrogen-containing compounds are either cyclic amine/aldehyde condensation products (with ring N) or the reaction products of polyisocyanates with organic compounds having reactive hydrogen.  Typical intumescing agents generating their own carbonaceous residue according to the invention are conden-sation products of ethylene-urea with formaldehyde, and of melamine or glycerol with toluylene diisocyanate.
