Title: Wind turbine with transverse shaft
Inventor: ADANT PIERRE-PAUL
IPC: F03D3/06
Filed: 1998-11-18
Abstract: The invention concerns wind turbines comprising at least one vane. Each vane is mounted on a countershaft so as to rotate freely about it, or with it. Each countershaft is integral with a main shaft. The main shaft must be oriented transversely to the wind direction. A mechanism connects the vane and the main shaft such that, for one rotation of the vane about its countershaft, the main shaft also competes one rotation. Said mechanism is produced with mechanical means such as gears, universal joints and other joints, flexible shafts. When the main shaft is in a horizontal position, said wind turbine does not require a pylon, but a simple support. Each vane describes a trajectory located above the main axis.

Abstract: ABSTRACT                "Farrowing Crates" In order to confine a sow in such a manner as to allow only limited movement of the sow, the crate has two side  members  (2,  3)  each  of  which is pivoted at a corresponding end about  a  respective  vertical   axis and between which  the sow is positioned in use. Each of the side members (2, 3) comprising a rigid frame incorporating at  least  two  horizontal  rails.   A linkage system (11) couples  together the  side  members  (2,  3)  such  that pivoting of one of the side members in one direction about the associated vertical axis causes corresponding pivoting of the  other side  member in the opposite direction about the associated vertical axis.   Furthermore a damper (17) is  incorporated  in  the  linkage  system  (11)  so as to control pivotal movement of the  side  members  (2,  3) in such a manner that, when the sow applies her weight to one of the side members  on lying  down within  the crate, the side member  gives way gradually under the to the weight in order to lower the sow controllably  to  the  ground.   A particularly efficient farrowing crate is provided by this arrangement.     (Figure 2)

Title: Method for identifying formation fractures surrounding a well casing
Inventor: MEDLIN WILLIAM L
IPC: G01V1/44
Filed: 1990-03-15
Abstract: An acoustic borehole logging tool traverses a fluid-filled cased well with an acoustic energy transmitter.  Pressure waves created in the well fluid by the transmitter generate tube waves in the well casing.  A closely spaced receiver detects tube waves that have travelled along the cased wellbore and been reflected by fracture interfaces.  These reflected tube waves are recorded and used to identify the top and bottom of any fracture interval in the formation behind the well casing. This method can also be applied to determination of the effectiveness of a hydraulic fracturing operation in a subsurface formation behind a well casing.

Abstract: ABSTRACT OF THE DISCLOSURE      A system for transmitting a comb of radar signals.          The invention includes a phase shifter for shifting the phase of an input carrier signal.  A frequency modulation signal is adjusted in amplitude by an attenuator 16 and input to a balanced mixer 14.  The balanced mixer 14 mixes the input carrier signal with the attenuated frequency modulation signal.  A summer 20 combines the output of the phase shifter 12 with the output of the balanced mixer 14.   The system 10 of the present invention provides an inexpensive means of generating and receiving a complex of illuminating signals having a spread spectrum consisting of lines (teeth) of carrier frequencies with controllable power.  The system 10 is agile in that the power levels and the spectral positions of the teeth may be varied.

Abstract: MULTI-FUEL ENGINE CONTROL WITH FUEL    COMPOSITION RESPONSIVE FUEL VISCOSITY CORRECTION            Abstract of the Disclosure A vehicle engine fuel control adapted for multi-fuel operation uses a fuel injection system in which fuel in a liquid mixture of first and second combustible fuels is injected in pulses of controlled duration at a predetermined pressure to achieve a predetermined air/fuel ratio.  The first and second combustible fuels have different viscosities, so that the viscosity of the mixture changes with its composition as well as fuel temperature.  The duration of the portion of the pulse duration in which fuel flows is varied in response to fuel composition and fuel temperature so as to compensate for the variation in viscosity of the fuel mixture and thus deliver the required amount of fuel with each pulse.

Inventor: NAGY ALEX J
IPC: F04D17/08
Filed: 1990-12-05
Abstract: ABSTRACT          A compact efficient fan which utilizes an improved impeller.  The impeller allows no slippage of air within its cylindrical volume.  This results in a fan which has a discharge which is directly proportional to its RPM.  The impeller comprises a cylindrical hub having a plurality of wheel blades affixed peripherally therearound.  The blades are each constructed from a sheet cut to a pattern having end portions which are bent forward to form a cupped blade.          The end portions of the blade shear inlet air and rotatably accelerate it to the central blade portion.  In the central blade portion, the air received from the end blade portions is further accelerated both in the direction of rotation and radially outwards.  The outwards acceleration is facilitated by a back slope (from a radial line) of the central blade portion. The cylindrical hub is affixed on a shaft which is rotatably mounted to an angular frame.  The angular frame also supports and positions a scroll shaped housing which encloses the impeller.  Means to drive the impeller may be supported and positioned by the frame.

Abstract: A method of affixing a plurality of tubes into a plurality of corresponding openings in the header wall of a heat exchanger in which the wall has an inner, liquid-facing side and an outer, air-facing side.   Ends of the tubes are welded to corresponding collar openings in the header wall, such that the tubes extend toward the air-facing side of the wall,  to form a plurality of welded tube-to-header joints.   Flux is applied by spraying or the like to the air-facing side of the tube-to-header joints.   Thereafter, a lead/tin or other molten solder is applied to the liquid-facing side of the tube-to-header joint by dipping or wave solder techniques and flowed into any voids in the welded joints to substantially seal the joints against leakage of liquid. Only those joints having potential liquid leaking voids receive the solder; sound, liquid-tight welded joints are not solder sealed.
