  • Patent number: 5265470
    Abstract: Methods and apparatus for measuring gravitational and inertial forces, magnetic fields, or wave or radiant energy acting on an object or fluid in space provide an electric tunneling current through a gap between an electrode and that object or fluid in space and vary that gap with any selected one of such forces, magnetic fields, or wave or radiant energy acting on that object or fluid. These methods and apparatus sense a corresponding variation in an electric property of that gap and determine the latter force, magnetic fields, or wave or radiant energy in response to that corresponding variation, and thereby sense or measure such parameters as acceleration, position, particle mass, velocity, magnetic field strength, presence or direction, or wave or radiant energy intensity, presence or direction.

  • Patent number: 5216439
    Abstract: Data is recorded with a plurality of clocked recording elements in a plurality of recordings in a plurality of different scales determined by different data recording parameters. Data recording parameters for any scale are electronically fixed for each recording in that scale, and are stored in a lookup table. Such stored data recording parameters are derived from that lookup table for determining the clocked recording elements for data recording in the particular scale, and data is recorded with such determined clocked recording elements in that scale.

  • Patent number: 5211051
    Abstract: Methods and apparatus for improving performance of a sensor having a sensor proof mass elastically suspended at an initial equilibrium position by a suspension force, provide a tunable force opposing that suspension force and preset the proof mass with that tunable force to a second equilibrium position less stable than the initial equilibrium position. The sensor is then operated from that preset second equilibrium position of the proof mass short of instability. The spring constant of the elastic suspension may be continually monitored, and such continually monitored spring constant may be continually adjusted to maintain the sensor at a substantially constant sensitivity during its operation.

  • Patent number: 5211195
    Abstract: A fluid valve has a valve housing defining a corner and having a valve housing cover opposite that corner. That valve housing and cover enclose a valve chamber therein. A fluid inlet or outlet is in the valve housing cover. First and second valve seats for further fluid inlets or outlets are in first and second sides, respectively, of the corner in the valve chamber. A flapper is in that chamber for selectively closing the first valve seat and alternatively the second valve seat. A flapper actuator is in the corner of the valve housing. There may be an expansible valve closing member for each valve seat. Such expansible valve closing member may have an aperture paralleling that valve seat. A pilot valve may be at the expansible valve closing member for closing its aperture. Opening of the valve is initiated by moving the pilot valve away from the aperture in the expansible valve closing member, and such opening of the valve is completed by pulling the expansible valve closing member away from its valve seat.

  • Patent number: 5158069
    Abstract: A wind-resistant heating appliance has a housing with air inlet openings for sustaining combustion generating flue products inside that housing which also has an outlet for flue products. The heating appliance has a top structure above that outlet and the housing. A top wall of that top structure is penetrated with exhaust openings for flue products along opposite edges of that top structure. The outlet between the housing and the top structure is provided with a transverse outlet channel inside the top structure and has opposite ends open at the exhaust openings adjacent the opposite edges of the top structure. That transverse outlet channel is solidly enclosed along its top, sides and bottom between the opposite ends, except for the outlet between the housing and the top structure. The exhaustion of flue products in various wind conditions is further aided by increasing the speed of flue products passing through the outlet from the housing to the transverse outlet channel.

  • Patent number: 5137216
    Abstract: Multiple unit drip irrigators use several self-contained on-line drip irrigation devices, each comprising a distinct housing having a liquid inlet, a tubular liquid outlet and containing a labyrinthine liquid path between such inlet and outlet. A common manifold contains the several drip irrigation devices. Such manifold has a common liquid inlet communicating through a space in that manifold with the liquid inlets of the drip irrigation device housings. The manifold has as many distinct internal supports for the housings of the drip irrigation devices as there are drip irrigation devices. Each of such internal supports has a bore for receiving the tubular liquid outlet of one of the housings of the on-line drip irrigation devices and each of such internal supports has an individual outlet terminal extending from the bore in that internal support to an outside of the common manifold.

  • Patent number: 5061444
    Abstract: Objects are protected against deposition of fluid-borne particles in a diameter range of from one-hundredth of a micron to several microns from a convection boundary layer flow, by establishing a temperature difference between surfaces of these objects and fluid adjacent thereto such that the temperature of these surfaces is higher by not more than 10K than that of the adjacent fluid, to such an extent that the thermophoretic effect dominates the combined effects of Brownian motion and gravitational deposition of the particles in the boundary layer flow. Highly advanced articles of manufacture are produced when those surfaces are changed structurally, such as during manufacture of integrated circuits, while the thermophoretic effect dominates the latter combined effects.
