Abstract: A system for inducing implosion shock forces on perforation traversing earth formations with fluid pressure where an implosion tool is selected relative to a shut in well pressure and a tubing pressure to have a large and small area piston relationship in a well tool so that at a predetermined tubing pressure the pistons move a sufficient distance to open an implosion valve which permits a sudden release of well fluid pressure into the tubing string and produces an implosion force on the perforations. A pressure gauge on the well tool records tubing pressure and well pressure as a function of time.

Abstract: A geodesic sphere phased array antenna system, capable of scanning the entire omni-directional communication space and comprising substantially equilateral triangular planar subarrays of antenna elements arranged in a geodesic sphere configuration. Icosahedron, one of the five regular solids and truncated icosahedron, one of the fifteen semi-regular solids are the preferred basis of the geodesic sphere phased array construction. The entire communication space is considered as subdivided into a large number of smaller cells and corresponding to each such cellular communication space, a contiguous set of the subarrays is energized and electronically phased to scan the cellular space.

Abstract: This invention discloses a method for rapid visual exploration of a volume of seismic data which does not require horizon picking or editing and yet displays all horizons with their stratigraphic features and lithologic variations in 3-D motion on a color graphics workstation. Seismic data is processed to generate multiple attributes at each event, location of a specified phase of the seismic trace, within the 3-D survey volume. Subsets of multiple attributes are interactively selected, thresholded and combined with one out of a suite of mathematical operators into a scalar function which is mapped onto a user selected color spectrum. Three dimensional features, where geological structure and stratigraphic compartments, including those that cannot be detected with conventional techniques, automatically emerge in the 3-D volume as the composition of attributes in the subset, threshold limits of attributes or the mathematical form of operator is interactively varied.

Abstract: A protective garment (10) adapted to be worn by personnel in high temperature or otherwise harmful environments. Tile garment comprises a torso section 11 and depending on the wearer's needs and desires, arms (14), head (13) and leg sections (15) and readily attachable complementary portions for covering the face, hands and feet extremities.

Abstract: The invention is an apparatus for producing fountain displays which include moving variable-play fountain sprays and comprises one or more nozzles with dual entry or multi-entry ports which are mounted on one or more moveable floats and are connectable to a source of pressurized liquid through a control apparatus which includes an alternating valve and valve system for producing oscillating, stationary and intermittent nozzle dispersal streams. The moveable floats can be controlled to move by mechanically means or hydraulically by the thrust of one or more nozzle dispersal streams from an underwater nozzle or nozzles mounted below the waterline to thereby provide for complex movements of the various nozzle dispersal streams included in a particular fountain display.

Abstract: An integrated helmet and omnidirectional microstrip antenna system comprising a ballistic helmet constructed of rigid non-metallic material with a sheet of dielectric material as the top layer thereof and an omnidirectional microstrip antenna system having one or more antenna radiator elements affixed to the top surface of the dielectric sheet. The antenna radiator elements are circularly polarized by a microstrip feed network designed to provide circular polarization of a desired sense. A conductive layer of metallic material bonded to the underside of said dielectric sheet and integrated in the helmet structure serves as the electrical ground for the antenna.

Abstract: A harness for supporting a handgun holster adjacent the thigh of a wearer in a position relative to the wearer's torso which is maintained even though the wearer may be engaged in vigorous activity and precludes shifting of the holster as would disadvantage the wearer in an emergency situation. The harness includes a waist belt and at least one or a pair of substantially rigid shankpieces mounted to the waist belt to extend downwardly alongside the respective thighs of the harness wearer. On the lower end of each shankpiece is fastened a leg strap for tightening about the wearer's leg adjacent thereto and precluding shifting of the waist belt and shankpieces relative to the torso. The handgun holster is mounted on the outside of one of the shankpieces to extend downwardly alongside the thigh in offset relation thereto.

Abstract: A multi-color liquid display system comprising a transparent conduit and system for sequentially circulating liquids of different color and different specific gravity through the conduit to present a dynamic display such as "raining" of one liquid into another. The circulating system includes a reservoir, a pump, device for communicating liquids in the reservoir with the transparent conduit, and device for controlling the proportionate flow of the different colored liquids from the reservoir. The display system includes a panel assembly in which a front transparent panel is bonded to a second transparent panel in spaced relation thereto and the conduit for liquids is formed in a desired configuration between the panels. The sign is illuminated by back lighting and the front panel is coated to mask all but the portions of the sign to be illuminated.
