Coated sewing threads comprise a sewing thread and from about 0.1 to 20 percent by weight of the cross-linked nylon composition, based upon the weight of the thread.

Abstract: A low-profile, broad band monopole antenna (10) includes two linear radiators (11,13), a resistor network (18), and a transmission line network (20), all connected in series in that order. Linear radiator (11) includes a capacitor (12) which reduces the apparent electrical length of the antenna and provides high voltage isolation. Resistor network (18) reduces VSWR at lower frequencies in the band of interest such that in combination with the other elements, the VSWR for antenna (10) is sufficiently low that no further matching or tuning is necessary over the entire broad frequency band of interest without significant loss of gain relative to that of a monopole antenna one-quarter wave resonant at each frequency throughout the frequency band of interest.

Abstract: A breakaway utility pole (9, 109) mounting structure. The mounting structure presents a base portion (11', 16 or 20) within which the end portion (10, 110) of the pole (9, 109) is telescopically received. The base portion (11', 16 or 20) of the mounting structure extends below ground level, and an adhesive material (17, 117) bonds the pole end portion (10, 110) to the base portion (11', 16 or 20). The adhesive material (17, 117) is adapted to fail when the pole (9, 109) is subjected to an impact at a predetermined distance above ground level from a vehicle of predetermined minimum weight moving at a predetermined minimum speed.

Abstract: Polyphenylene sulfide blends with melt extrudable polymers form novel monofilaments. The monofilament is prepared by extruding a mixture of the linear polyphenylene sulfide and the melt extrudable polymer to form a monofilament blend, quenching the monofilament and thereafter drawing the monofilament to a ratio of from about 3:1 to 6:1. The resulting filament can be employed for the manufacture of fabric.

Abstract: The present invention is directed to a fishing rod (10) that is capable of providing a selectively variable action. That is, the rod (10) can be changed from a stiffer to a softer action not only while the rod is being prepared for casting a lure but also while the rod is being used to play a fish. The rod (10) has a sheath (13) with a handle (11) secured thereto such that the sheath (13) extends forwardly of the handle (11). The line and tip guides (14 and 15) are affixed to the sheath (13). The interior of the sheath (13) defines a hollow, preferably conical, cavity (25) that extends for at least one half the length of the sheath (13). A blade (30) that is preferably tapered in conformity with the taper of the cavity (25) within the sheath (13) is received within the cavity (25), and means (31) are provided selectively to translate the blade (30) longitudinally within the cavity (25) and thereby selectively vary the action of the rod (10).

Abstract: A reel mount incorporated within the handle (10) of a fishing rod. The gripping portion (14) of the handle (10) has a smoothly contoured exterior gripping surface (14) and a hollow, interior cavity (20) into which the foot (15) of a reel (16) may be received. An aperture (23) penetrates the gripping surface (14), and the foot (15) may be button holed through the aperture (23) to be received within the cavity (20). A seating surface (45) is provided at the longitudinal extremities of the aperture (23), and a pressure plate (38) is translatable demountably to secure the foot (15) between the seating surface (45) and the pressure plate (38). A threaded shaft (36) is attached to the pressure plate (38), and an adjusting nut (35)--which threadably engages the shaft (36)--is rotatably received within a passageway (32) oriented transversely through the handle (10).

Abstract: A blend of two resins forming a novel monofilament comprises from about 50 to 95 parts by weight of a linear polyphenylene sulfide and, from about 5 to 50 parts by weight of a melt extrudable copolymer consisting essentially of an olefin and a halogenated monomer. The monofilament is prepared by extruding a mixture of the linear poly phenylene sulfide and the melt extrudable copolymer to form a monofilament and thereafter drawing the monofilament to a ratio of from about 3.5:1 to 6.0:1. The filament can be employed for the manufacture of fabric.

Abstract: An integrated control mechanism for an electric fishing motor (10). The electric fishing motor (10) has a motor tube (11) with a propulsion unit (12) secured to one end and a control head (16) mounted on the other end. An articulation assembly (35) has a frame portion (36) secured to the housing (28) of the control head (16) and a bracket portion (38) attached to the motor tube (11). The assembly (56) which effects the pivotal connection between the frame and bracket portions (36, 38) also accommodates selectively positioning the control head (16) radially about the axis (58) of the motor tube (11). A tiller (60) is secured to the frame portion (36), and an on/off switch (89) is operatively connected between the frame and bracket portion (36, 38) such that vertical manipulation of the tiller (60) articulates the assembly (35) to actuate the on/off switch (89).

Abstract: A metal connector (10) for the end portion of a plastic tension rod (12) having a continuous wedge-shaped internal helical groove (18) adapted to be filled with bonding material (21) bonded to the rod (12) and non-adherent to the metal surface of the groove (18).

Abstract: An umbrella frame having an upper mounting member (11) fixed on the upper end of a central shaft (10) and a lower mounting member (12) slidable on said shaft with a circumferential series of outer ribs (13) pivoted at the upper end to the upper mounting member (11), and stretcher rods (16) pivotally connecting intermediate portions of said ribs (13) to said lower mounting member (12).

Abstract: The present invention is directed to a hollow, flexible rod (20) having a body portion (21), a tip portion (23) and a transition portion (24) between the body and tip portions. A plurality of reinforcing strands (30) of a first material extend longitudinally within the body portion (21) and into the transition portion (24). A plurality of reinforcing strands (31) of a second material extend within the tip portion (23) and into the transition portion (24). The reinforcing strands of the first and second materials overlap one or more integer multiples (N) along the circumference of the rod. The present invention is also directed to the method whereby independent prepreg sheets (26,28) formed of the first and second reinforcing strands (31,30) are cut to a tapered apex (33 or 34) and overlapped to a predetermined, interrelated extent longitudinally (T) and laterally (S). So overlapped, the prepreg sheets (26,28) are simultaneously wound onto a mandrel (29) and cured to produce the aforesaid rod (20).

Abstract: The present invention relates to FRP members, the apparatus and process for making same. The FRP members are reinforced with helical strands of reinforcing material disposed in expanded helices of opposite hand, the helices of each hand being contained in discrete layers. The lead angle of each helix may be constant or varied along the length of the member independently of whether the member is cylindrical or tapered in order to provide the desired structural characteristics. The process comprises impregnating the reinforcing strands with resin and wrapping those strands onto a mandrel by apparatus in which relative rotational as well as relative translatory movement between the mandrel and a winding head may be effected to wrap the strands onto the mandrel. At least one relative movement may be selectively varied to effect the desired lead angle to the helically disposed reinforcing strands along the length of the mandrel.

Abstract: An apparatus for making fiber reinforced plastic members. The apparatus employs a rotatable mandrel (18) and a winding head (16) with a unique arrangement by which to effect relative longitudinal movement between the winding head (16) and the mandrel (18). Either the winding head (16) or the mandrel (18) may be longitudinally fixed. The other of those members is mounted on a trolley (30) that can be reciprocated parallel to the longitudinal axis (42) of the mandrel (18). This reciprocation is effected by having a dog means (51) mounted on the trolley (30) that is movable between a first and second position. In the first position the dog means (51) engages a lug (50) on a drive means to move the trolley (30) in one direction, and in the second position the dog means (51) engages the lug (50) to move the trolley (30) in the opposite direction.
