  • Patent number: 4330873
    Abstract: This invention utilizes data collected in the course of reflection seismic prospecting methods to produce a map, such as a vertical profile or a three-dimensional picture, of subterranean earth formations. This is accomplished by aplanatic mapping of received seismic wave trains in the memory unit of a computer taking into account the travel times of waves, the location of the source, the location of the receiver, and the velocity with which the waves travel from the source point to the deflecting point in the earth and from then to the receiver. The data recorded by each source receiver doublet is digitalized and stored aplanatically in the memory unit, taking into account both signs and amplitudes of the signals. The accumulated data represents a map of the earth formations. Sections of this map are plotted to provide desired views of the formations.

  • Patent number: 4320472
    Abstract: This invention is concerned with systems for converting seismic waves received at various points at the surface of the earth into digital signals and the transmission of those digital signals from the geophone stations to a recording truck. Address registers located at the geophones are employed to permit periodic selective interrogation of the individual geophones. Typically, electric signals generated in the geophones, such as digital seismic signals, are time-multiplexed for return to a recorder over a common cable.

  • Patent number: 4259541
    Abstract: An improved multiple-mode damper for damping Aeolian vibrations of electrical cables is provided which employs a single mass and two resilient support members that are respectively connected between separate points of the mass and separate points of the cable. One resilient support member is located at or near the center of the mass and the other at a point remote therefrom. The resilient support members are composed of spring components and elastomer components that act in parallel. The elastomer material has a Shore hardness of at least 30 and a damping coefficient that is at least 10% of the critical value. The stiffness of the elastomer component is at least 10% of the stiffness of the spring and it is preferably greater than that of the spring.

  • Patent number: 4240215
    Abstract: A self-cleaning, or anti-fouling, shoe spike structure is provided that includes an elongate normally vertical earth-engaging spike with upper and lower ends, means securing the upper end of the spike on a shoe with said spike depending from a normally downwardly disposed earth-engaging surface of the shoe and self-cleaning means comprising an annular debris-repellant barrier positioned about the upper end of the spike. The barrier may be in the form of a movable washer that projects outwardly from the spike and underlies the shoe surface. Or it may be in the form of a stationary non-wetting member surrounding the spike. The barrier operates to allow for substantially free movement of soil and other debris about the upper end of the spike and the portion of shoe surface about the spike thereby preventing accumulation and compaction of soil or other debris on the bottom of the shoe about the spike.

  • Patent number: 4124888
    Abstract: A distributed input/output system is disclosed for controlling numerous peripheral devices and the transfer of data signals and control signals between those devices and a general purpose digital computer. The control system described includes a multiplexer which can accommodate as many as eight input/output devices under the control of separate programmable microcoded peripheral-unit controllers. Each controller is adapted to be located at or on an individual peripheral device and each is connected to the multiplexer by an identical ribbon cable that is employed to carry both signals and power. Each controller employs a substantially identical microengine, that is, a microcoded processor, currently of five integrated circuit chips. The peripheral-unit controllers may be configured somewhat differently depending upon whether the peripheral device utilizes data signals in parallel or in series.

  • Patent number: 4095775
    Abstract: The invention is employed for evaluating particles, such as droplets of aerosol sprays suspended in a gaseous medium. A stream of the particles to be analyzed is flowed into a narrow sample zone across the optical axis of a beam of light. Scattered radiation from the particles is focused on the image plane in which a photosensitive surface is located. Images of particles formed there are reproduced on a fluorescent or phosphorescent display screen of a cathode ray tube. A scale on the screen is employed for measuring the dimensions of the particles. The confinement of the stream of the mixture to about the depth of focus of the objective lens of the camera reduces effects of out-of-focus particles and permits evaluation of individual particles.

  • Patent number: 4093933
    Abstract: The invention is concerned with a pressure diaphragm that is composed of a nonmetallic material that has been sculptured by etching a plate to form thick motes, or islands, and a thick rim interconnected by thin sheet material. The thick portions are separated by thin flexures in which the deflection of the diaphragm is concentrated, whereby the deflection yields a high value of electric output per unit pressure.

  • Patent number: 4065970
    Abstract: A diaphragm for a miniature pressure transducer has its surface sculptured by anisotropic etching to provide gauge areas in the form of narrow thin flexure areas between thick areas in the form of islands or motes. The thick areas act to constrain or stiffen the flexure areas from bending along their lengths while facilitating the bending thereof about axes parallel to their lengths when the diaphragm deflects in response to a pressure change. Linear piezoresistive gauges diffused into the gauge areas are responsive to the bending of said flexure areas to change resistance by an amount corresponding to the pressure change.
