Abstract: PROCESSES FOR HEAT TREATING FERROUS MATERIAL             Abstract Rod and wire or other ferrous material is annealed, normalized, spherodized, etc. in a furnace under nitrogen based atmospheres to which is added a mixture of methylacetylene and propadiene.  This latter mixture reacts with decarburizing substances such as carbon dioxide in the furnace at relatively low temperatures of about 1000-1100°F to substantially preclude decarburization of the ferrous material.  The use of a mixture of methylacetylene and propadiene in the amount of approximately 0.1-10% by volume of the furnace atmosphere also results in a relatively high CO level, reduces decarburization and oxidation of the ferrous material.

Abstract: ROTATING FLUID MANIFOLD  ABSTRACT        Disclosed is a method and apparatus for maintaining fluid flow between a subsea wellhead riser conduit 10, 12, 14 and a weathervaning floating production, storage and off-loading (FPSO) vessel without swivel or sliding seals.  The riser conduit 10, 12, 14 is divided into first and second flowpaths A, B which terminate in connectors 22, 24.  First and second drums 34, 36, coaxially mounted for rotation about a vertical axis, have connectors 26, 28 which are connectable with the flowpath connectors 22, 24.  The drum connectors 26, 28 are connected to one end of flexible pipes, 41, 41? 43, 50, 51, 52, at least partially wound around a respective drum, with the other end tensioned and connected fixably to the FPSO vessel.  Enough flexible pipe is on each drum 34, 36 to permit the drum to rotate about a connection arc of greater than 180° when its respective connector 26, 28 connects one flowpath with the FPSO vessel.  The connectors and drums are disposed such that each connection arc overlaps the other arc at both ends of each arc.          Fluid flow is maintained through the first flowpath A until the weathervanins vessel approaches the end of the connection arc of the first drum, 34.  After the overlap region is reached flow is established in the second flowpath B through the second drum 36 and flowpath connector 24.  When the end of the connection arc of the first drum 34 is reached, the first flowpath connector 22 is disconnected thereby terminating fluid flow in the first flowpath A while fluid flow is maintained in the second flowpath B.  Should further weathervaning continue such that the first drum connection arc is again reached, reconnection of the first drum 34 and flowpath A occurs.

Abstract: AUTOMATIC CONTINUOUS NULLING OF ANGULAR RATE SENSOR An angular rate sensor comprising a pair of accelerometers that includes means for continuously nulling error signals resulting from misalignment of the accelerometers. The first accelerometer (10) has a first force sensing axis and produces a first output signal (a1) indicating acceleration along the first force sensing axis. The second accelerometer (12) has a second force sensing axis and produces a second output signal (a2) indicating acceleration along the second force sensing axis. The accelerometers are mounted by mounting means such that their force sensing axes are both parallel to a common sensing axis and such that the accelerometers can be moved along a vibration axis normal to the sensing axis. A signal generator (76) produces a periodic drive signal having a predetermined frequency, and drive means (80, 82, 84) connected to the mounting means is responsive to the drive signal for vibrating the first and second accelerometers along the vibration axis at the predetermined frequency. Signal processing means (104) receives the first and second output signals and generates a Coriolis signal representing the Coriolis acceleration along the sensing axis resulting from movement of the accelerometers along the vibration axis and rotation of the body about a rate axis normal to the vibration axis andto the sensing axis. The signal processing means includes the detection means (92) that receives the Coriolis signal and produces a feedback signal that is a function of those components of the Coriolis signal that are in phase with respect to the drive signal. The drive means includes means (80) for combining the feedback signal with the drive signal, such that the in phase components arecontinuously driven towards a null value.

Abstract: Method And Apparatus For Foaming High Viscosity Polymer Materials Abstract of the Disclosure Polymer materials having viscosities ranging from 1,000 up to above 1,000,000 centipoises are mixed with a gaseous foaming agent to provide a polymer/gas solution under pressure such that when the polymer/gas solution is subsequently dispensed at atmospheric pressure the gas is released from the solution and becomes entrapped in the polymer material to form a homogeneous polymer foam.  Mixing is accomplished by a disc mixer which includes a tubular housing, a pair of substantially parallel, oppositely driven shafts extending along the length of the housing, and a series of spaced, solid, flat discs fixedly mounted on each shaft perpendicular to the axis thereof.  The discs on one shaft intermesh with the discs on the other shaft to form a series of compartments spaced along the length of the mixer.  The foaming gas enters into solution in the polymer in the compartments between the rotating discs.  The process is charac-terized in that relatively high viscosity polymer materials are foamed with relatively low horsepower requirements, high throughput and low temperature rise of the polymer from conversion of the work of mixing to heat.
