Abstract: Inventor:    J. WARNE CARTER, JR. and J WARNE CARTER, SR.       Invention:   WIND-DRIVEN GENERATOR APPRATUS AND METHOD              OF MAKING BLADE SUPPORTS THEREFOR                     Abstract of the Disclosure Wind generator apparatus employs an induction generator with a wind-driven rotor.  Connection of the induction generator to AC power lines is controlled by apparatus that compares generator rpm and line frequency. The rotor blades have a pretwisted, varying-chord inboard portion and an untwisted, constant-chord outboard portion. The blades are self-starting, operate efficiently over a range of wind speeds with constant pitch maintained by a torsional biasing mechanism, and pitch up automatically when the normal rpm operating range is exceeded.  An im-proved blade-supporting spar of low torsional stiffness has an I-beam configuration with filament-wound flanges. A pitch damper prevents torsional oscillations while permitting the blades to pitch up readily.  The rotor, which includes a teetering hub, is free to weather-vane about the axis of a supporting tower, but a yaw damper limits angular velocity.  A guy wire and gin pole arrange-ment stabilizes the tower and permits easy raising and lowering of the tower.

Abstract: ABSTRACT          A method for decreasing the density of a substantially closed-cell thermoplastic resin foam material by the secondary expansion thereof.  The method comprises increasing the gas pressure within the cells, retaining that elevated cell pressure for pro-longed periods and then heating the foam material above its heat plastifying temperature to cause secondary expansion thereof.  In an example, a low density poly-ethylene material was foamed to produce a foam with a density of approximately 0.085 grams per cubic centimeter. This foam was then pressurized with nitrogen and afterward secondarily expanded to produce a foam with a density of approximately 0.036 grams per cubic centimeter.

Abstract: Abstract An apparatus for diagnosing a plurality of digital to-analog converters simultaneously is provided. Digital signal generation means applies digital signals to the plurality of digital-to-analog converters, and the digital signals are changed in sequence so that the analog outputs from the con-verters are changed symmetrically with respect to a first predetermined value.  The analog otuputs from the converters are combined by a resistor network, and the combined output is compared with a second predetermined value by a comparator.  If the comparator's output is kept to a predetermined level regard-less of changing the digital signals, the digital-to-analog converters are judged that they operate properly.

Abstract: METAL MACHINING DEVICE WITH CONTROL CIRCUIT ISOLATION                ABSTRACT OF THE DISCLOSURE         A metal machining device includes a pair of longitudinally movable gantries and a connecting trans-verse bridge which mounts carriages which carry machining tools.  A computer numerical control unit is fixedly mounted adjacent one end of the bridge and is connected to supplemental electronic circuits.  The transverse tool-carrying bridge is formed as a generally hollow heavy-walled closed box-beam which has mounted therein at least part of the supplemental electronic circuitry.  A beam side-wall is provided with a plurality of doors which open to permit access to a plurality of circuit-holding drawers.  When the doors are closed, the bridge forms a unitary hollow housing containing the supplemental elec-tronic circuitry which serves to mechanically and elec-tronically isolate them and substantially reduce the radiation of electronic noise therefrom to the computer. The removal and harness-like fixing of at least some of the connecting electronic cables to within the bridge serves to reduce the problems of electronic coupling and other interference.  Further improvement in isolating is accomplished by placing progressively noisier supplemental circuits in drawers which are progressively farther away from the computer.

Abstract: FLOW DIVERTER                       ABSTRACT    Apparatus adapted for connection to a drilling conduit beneath a drilling rig floor for diverting pressurized well bore  fluid  in the conduit from the rig and  sealing  the annulus between a pipe or other object and the conduit or closing the vertical flow path of the conduit in the absence of any object in the conduit is disclosed.  The apparatus includes  a  housing,  an  annular  packing element and two pistons.  The housing is provided with at least one outlet passage in the wall of its body, and one of the two pistons acts  as  a sliding  sleeve valve in  cooperation with  the housing wall for preventing fluid communication between the outlet passage and the interior of the housing when it is in a  nonactuated  or normal position and  for allowing  fluid communication  when  it  is  in an  actuated  or  diverting position.    The second piston is advantageously disposed  axially upwardly within the housing and is adapted for engagement with the upper part of the first piston after the  first piston has moved an upward axial distance  sufficient  to insure  opening  of  the  outlet  passage  before  the  upward movement  of  the  first  piston  urges  the  second  piston upwardly  thereby  causing  the  annular  packing  element  to close about an object in the housing bore.    Another embodiment of the invention provides two outlet passages in the housing wall and two holes in the  first piston.  When the first piston is in the normal position, one of its holes is in alignment with one of the housing outlet passages, while the other outlet passage is covered by a portion of the piston wall.  When actuated, the piston closes the previously opened outlet passage and opens the previously closed outlet passage.

Abstract: Mounting Arrangement for an Exhaust System Abstract This invention relates to a mounting arrangement for resiliently connecting an exhaust stack to an exhaust pipe and a frame which eliminates the problems of vibration, noise transfer, joint failure, high exhaust temperatures, complexity, and inability to quickly assemble and disassemble.  The mounting arrangement has first and second spaced apart elastomeric devices for resiliently connecting the exhaust stack to the frame, a support bracket and an exhaust pipe.  The first elastomeric device supports an open end of the exhaust pipe in the exhaust stack and on the frame and the second elastomeric device engages the support bracket and which retains the first elastomeric device in contact with the frame.  A passage arrangement passes cooling air flow past the first elastomeric device to cool the first elastomeric device and the exhaust stack.  Thus the problems of vibration, noise transfer, joint failure, high exhaust temperature, complexity and difficulty of assembly and disassembly are eliminated.  The mounting arrangement is particularly suited for connecting the exhaust stack to the frame and an overhead guard of a lift truck.
