Abstract: An apparatus and method for installing pull lines in conduits and retrieving the installed pull lines with an attached electrical cable through the conduit is disclosed. The apparatus provides a single structure which both installs the pull line and retrieves the installed line with a, for example, electrical cable or a heavier pull line attached. The device features an elongated valve actuating handle provided with a line containing reel. A driving pneumatic force can be attached to the handle operable through the valve portion thereof. The handle is provided with a chamber at its end portion which dispenses both the pull line from the reel, and driving pneumatic pressurized fluid. The device is provided with a vehicle which sealably contacts the walls of any conventional conduit and travels therethrough with the end portion of the pull line from the reel attached thereto.

Abstract: A high fidelity loudspeaker system involving a multidriver, semi-omnidirectional, full range, electrodynamic loudspeaker including two, separate but complementary, closed box-like enclosures, an upper unit containing an array of mid-range speakers around three sides and a lower unit containing arrays of low and high frequency speakers around three sides. The low frequency speakers (woofers) on their interior sides include a series of tubes opening into the closed interior of the speaker enclosure, having various lengths in accordance with certain relative, locational relationships. Although the low and high frequency speakers include a single crossover frequency circuit, the "mid-range" speakers are not included in any crossover network but are driven throughout the total frequency input range, although a capacitor can be included to cut off the very low frequencies to the mid-range speakers.

Abstract: A method and technique for a deviated (non-vertical) emplacement of a conductor casing at a desired curver and orientation in order to facilitate directional drilling of a well in the substratum of an offshore well site. The method provides for the installation of a relatively short, offset portion of the conductor casing at only the bottom of the conductor pipe string and thereby utilizing this offset portion to force the conductor string in a desired direction and orientation by driving or forcing the conductor casing through a substratum in such a manner that the casing will assume the desired curvature and direction as it advances through the substratum. In addition to the offset or dog-leg segment at the bottom, key-way type guide bars can be added in the longitudinal direction to resist undesired rotation of the conductor pipe.

Abstract: An improved method of and structure for mooring for example supertankers offshore which combines the mooring process and the connections of cargo transfer lines into one simple operation and includes a mooring buoy capable of fluid transfer which is particularly adaptable to a super port type operation. The buoy includes a relatively long flotation caisson structure having a relatively small diameter, such proportion insuring greater stability in rough sea conditions. A flow line is located down the center of the buoyant caisson and extends above the bow of the ship it will service. A fitting is located on the top end of the flow line which is capable of securely attaching to a mooring pedestal located on the bow of the ship. This arrangement allows fluid flow between the riser structure and the ship as well as forming a substantial mooring linkage between the ship and the anchor lines which are attached to the bottom of the buoy. The system also includes the use of a mooring winch on the ship.

Abstract: A specially designed roller for shrimp peeling machines which includes a gapped portion along its length, for example at its upper end, to effectively shorten the effective peeling section of the machine without substantial modification of the basic machine itself by allowing the shrimp to fall through the gapped portion rather than traversing the full length of the roller. Heretofore, separate, different machines were necessary to achieve the highly desired advantages of the present invention. The special, gapped rollers are substituted for the standard peeling rollers which provide peeling action along their full length, when an effectively shorter peeling section is desired. Several different gapped rollers are disclosed, some reversible end-for-end and others forming a series of subsequently related rollers which have a varying location of the gap portion along the roller length.

Abstract: An educational and recreational game having a case-like rectangular basic structure including an outer support structure and an interior frame with interchangeable principal transparent playing elements and insertable underlying complementary transparent elements which upon insertion change the style of recreational play and introduce various mathematical relationships represented by lines on the elements into the game. The complementary elements or inserts singularly and collectively form a series of mathematical figures which are used in basic and advanced mathematics and are used in the game for instructional purposes. There are several circular openings in the principal playing surfaces with associated arch-shaped, cylindrical targets and stops located atop the principal playing surfaces. Structure is provided for retrieving the balls which roll upon the principal playing surface.

Abstract: An improved deck form supporting system for supporting sectional floor forms between bridge girders, for example concrete girders on top of which floor forms cementitious material is poured to form a concrete floor. The novel supporting system is located below the sectional floor forms and includes a series of evenly spaced wedges, usually triangular in shape, placed along the lower inclined or slanted surfaces of the suppoting girders (FIG. 4) along with a series of "L" shaped brackets which mate with the horizontal and vertical surfaces of said wedges (FIG. 5), the brackets having vertical and horizontal tubular extensions having jackscrew sections therein, the combination being used to support on "U" shaped shoring brackets (FIG. 3) horizontally, laterally disposed forming members placed between the bridge girders (FIG. 2) to support the floor forms.

Abstract: A hair weaving tension system utilizing a thread supply tension device (note FIG. 1) comprising a vertical support pole having three spools of thread separately housed within three tension members which resist and control and thereby tension the thread as it is pulled by the operator for use in weaving bands of hair on the head of a person as a hair styling technique (note FIG. 4). The resistance or tension on each thread is produced by a cylindrical housing having a thread opening therein and a mating, cylindrically surfaced bearing member which bears against the housing and thereby against the thread coming through the thread opening (note FIGS. 2 and 3). The frictional drag on the thread can be varied by a set screw whose position can be used to vary the force that the bearing member applies against the housing.
