    • A method and apparatus is shown and described for remotely closing a well(s) without the possibility of accidental closure. The method and apparatus will have a significant application to underwater wells. A point of activation of a gas generator is remotely located away from the well to avoid debris that may fall at or near the well. A diver or technician brings the means for activating the gas generator to the activation point of the gas generator. Upon activation, pressure generated by the gas generator is transferred by appropriate conduit means to well closure equipment which may include a crimping device, a "U" type blowout preventer, blind rams or any combination thereof. The faces of rams used to pinch concentrical strings of pipe may be shaped to seal the outer strings of pipe as well as inner strings.

    • The present invention provides a method of obtaining an organism which has been characterized as having cells containing exogenous genetic material which includes any sequence of DNA that can be distinguished as exogenous by known molecular biological analysis by insertion of genetic material into an animal's genetic makeup. The insertion of the genetic material is done by inserting DNA that has been complexed with molecules that allow the DNA to be inserted into the chromosomes when injected into the cytoplasm, perivitelline space, or placed in surrounding culture media to be taken up and incorporated into the genome. When the DNA is complexed into the polyelectrolyte molecules by electrostatic attraction, the electric charge of DNA of the complex is partially to substantially neutralized. The present method does not require the genetic material to be introduced into the embryo at a particular stage in development.

    • An optical scanning device for mechanically scanning images at a high scanate over a wide field of view and under low light conditions. The device comprises a first rotating reflecting means such as mirrors for intersecting an input beam of light in a first path and for redirecting the beam of light into a second path. A second rotating reflecting means intersects the second path and reflects the beam of light into a third path, onto a detecting device for detecting the presence of predetermined images in the beam of light. In order to reflect the light beams over an elliptical path the mirrors are mounted on rotating shafts at a slight angle from the perpendicular to the axis of the rotating shaft. The mirrors are rotated at varying speed relationships to each other and varying phase relationships to each other in order to produce a variety of scan patterns.

    • A regulator is provided in which the bias which urges the unseating of the regulating valve is a piston having a plurality of radial working surfaces, each in its own separate pressure chamber. The chambers are connected to the inlet selectively, singly or in combination, by solenoid valves. The unseating of the regulating valve is opposed by the outlet pressure which works on the entire back side of the piston. In the preferred form a relationship exists between the relative sizes of the individual piston working surfaces so that all the possible outlet pressures attainable by the regulator are equispaced, all the way from 0 psig to the highest regulated pressure.

    • A laser position sensor system for viewing a wide field of view for detecting the angular position of a remote laser. A laser beam directed toward the sensor from any position within a 90 degree circular field-of-view can be detected to a positional accuracy of less than 0.1 degree in a two-axis coordinate system. The system utilizes two parallel sensors having field-of-view optics that compress the field-of-view. The compressed output from each optics is directed through a polarizer and filter to a phase shifter. The phase shifter, a pair of birefringent crystals, encodes the angle of incidence of the laser beam as a phase shift between the two components of the polarized input beam. These components, the e-ray and the o-ray travel different paths through the phase shifter. Subsequently, an analyzer such as a Wollaston prism decomposes the beam into two linear components. These components are condensed through a reimager lens and coupled to a pair of intensity detectors. The detector outputs from each sensor can then be combined to provide a normalized signal proportional to a trigonometric function of the angle of incidence of the laser beam, indicative of its position in space.
    • 一种用于观察宽视野的激光位置传感器系统,用于检测远程激光器的角位置。 可以在双轴坐标系中检测到从90度圆形视野内的任何位置朝向传感器的激光束到小于0.1度的位置精度。 该系统利用具有压缩视场的视场光学器件的两个并行传感器。 来自每个光学器件的压缩输出被引导通过偏振器和滤波器到移相器。 移相器(一对双折射晶体)将激光束的入射角编码为偏振输入光束的两个分量之间的相移。 这些组件,e-ray和o-ray通过移相器传播不同的路径。 随后,诸如Wollaston棱镜的分析仪将光束分解成两个线性分量。 这些组件通过再成像镜头被冷凝并耦合到一对强度检测器。 然后可以组合来自每个传感器的检测器输出,以提供与激光束的入射角的三角函数成比例的归一化信号,表示其在空间中的位置。

    • A method and an apparatus for measuring the density variations, static and dynamic, in substances that are at least partially transparent to electromagnetic waves is disclosed. A special birefringement crystal phase shifting assembly encodes the angle of incidence resulting from the refractive effects of the electromagnetic waves having passed through a density variation. The angle of incidence is encoded as a poralization phase shift. Specifically, the poralization phase shift is between the ordinary and the extraordinary rays. That poralization phase shift has a known and definable relationship to the gas density experienced by the electromagnetic wave during its path.
