Abstract: A fishing rod assembly includes an elongated hollow fiberglass rod having an end plug secured to its butt or handle end, the end plug having an eyelet extending into the rod to which fishing line is attached. The fishing line includes a length of elastic line attached to the end plug and retained within the rod bore, and a length of nonelastic line coupled to the elastic line by means of a coupler and extending from the tip end of the hollow rod. The coupler coacts with a limit structure within the rod adjacent the tip end to prevent the elastic line from passing out of the tip end; and the limit structure may be a transverse pin or other internal protuberance such as a sleeve. A stop attached to the nonelastic fishing line coacts with the tip into the rod to limit withdrawal of the line into the rod and fix the limit of maximum contraction of the elastic line. An external finger projects from the rod tip end to coact with a locking loop in the line and fix the length of line which extends from the tip end.

Abstract: A triac functions as an electronic switch to intermittently connect the AC power circuit to a load, and is directly connected to the output of a 1422 integrated circuit timer which turns the triac on and off according to a controlled cycle. The timer functions as an astable multivibrator which alternately produces high or low output voltages responsive to movement of a control voltage between high and low trigger voltage levels. A charging circuit, including a capacitor and variable resistor, is connected directly between the DC power supply and the timer input to produce an increasing control voltage; and the control voltage is discharged through the timer to produce a decreasing control voltage which determines the duty cycle. The duty cycle is variable by means of a variable resistor in the charging and discharge circuits; and the control includes calibration for the time base.

Abstract: A wheel speed transducer, for each braked wheel of an aircraft, produces a DC voltage signal which is proportional to the wheel rpm. In one aspect, the system compares the wheel speed voltage signal with a fixed threshold voltage signal proportional to a selected wheel rpm which is indicative of a selected threshold ground speed such as 15 knots. When the threshold ground speed is reached, the system indicator advises that each wheel is or is not rolling at that speed. Another aspect of this system functions immediately after lift-off. The wheel speed voltage signal is compared with a modified wheel speed reference signal, which is maintained at a slightly lower voltage level for normal deceleration and which has a limited maximum rate of decrease determined electronically.

Abstract: A heavy duty press mechanism, whose ram is driven by means of an eccentric crank and pitman, carries a head with four aligned indention punches for distorting thread pitch simultaneously on four axially aligned hex nuts. A feed track system feeds a row of axially aligned hex nuts under the punch head. A reciprocating ejector-stop, synchronized with the punch ram, simultaneously ejects a group of four indented nuts and defines a stop for the following group of nuts at the indention station. A feed system includes an axial feed track for feeding nuts to the indention station, a lateral feed track, and a transfer speed coupler coupling these tracks. A vibrating hopper feeds laterally aligned nuts into the lateral feed track, where a single row of side-by-side nuts is fed by gravity to the speed coupler. The speed coupler effects a transfer from lateral feed to axial feed into the axial feed track.

Abstract: An elongated handle, of rectangular cross-section, has a round, flatted brush head mounted at either one end or both ends. The brush head, according to the invention is fabricated from an originally linear, twisted wire frame having a central core portion which secures diametral bristles which effectively project radially from the core portion, and free end portions. The core portion is formed into a circular core, with the free end portions extending transversely and being secured in an axial recess in the handle. The formed brush head, then, approximates a spherical head having opposite flatted sides. The handle end to which a head is secured is preferably bent at an obtuse angle, with the plane of one head core being transverse to the handle plane defined by the main handle portion and bent handle portion. When a second head of similar construction is mounted at the opposite end of the handle, the plane of the second head core is coincident with the above mentioned handle plane.

Abstract: For measuring and indicating phase voltage, phase sequence and other electrical values in a three-phase power system, and electrical values in single-phase and DC systems, a unitary instrument or apparatus includes a meter movement and three phase-resistors of equal value which are connected to a common juncture defining a neutral point, with a first phase-resistor connected in series with the meter. The three phases of the external circuit to be tested are connected respectively to the three phase-resistors through a three-pole three-position selector switch for selecting the three different phase to "phase-resistor" relationships. A switch connected between a third phase-resistor and the common juncture performs the alternative functions of opening or closing this circuit.

Abstract: Fibers enter a textile mill at bale breaking equipment where fibers are distributed onto an open conveyor, and possibly blended, for transmittal to processing machinery such as opening and cleaning equipment, picker equipment for forming a lap, carding equipment, and drawing, roving and spinning equipment. The fibers are carried on the open conveyor past a spray station including at least one nozzle for spraying a finely diffused liquid onto the surface of the fiber material carried on the conveyor. The liquid is an aqueous solution which consists of about 75% water and about 121/2% of animal or vegetable fats as an active compound which is converted ionic salt by reaction of the organic acids contained in the animal and vegetable fats with an amine and subsequently with an alkyl sulfate. After passing the spray station, the fiber material may be transmitted through pneumatic conveyor systems to the additional processing equipment which ultimately converts the fibers into yarn or thread.

Abstract: A primarily radial load ball bearing includes an assembly of outer and inner race rings having confronting raceways for a plurality of balls and a unitary ball separator fabricated of a moldable resilient material, having an annular base and annularly spaced fingers defining an interrupted cylindrical rib which projects between the outer and inner race rings and provides pockets for confining each of the balls of the bearing. Each finger defines a pedestal supporting at least two ears which are integral extensions of the pedestal and which are radially separated from each other. One ear extends into one adjacent pocket, and the other ear extends into the opposite adjacent pocket. The distance between the confronting distal lips of the ears for one pocket is less than the diameter of the ball, so that the ears define a snap-in entry to the pocket. The ears, then, are designed to be resiliently yieldable relative to the supporting pedestals.

The circuits for automatic brightness control include an amplification correction circuit which utilizes a portion of the amplified composite video signal to produce a DC correction voltage which is applied to the gain biasing circuit of one video amplifier stage to either increase or reduce the gain in response to the projected light, and a blanking correction circuit provides a DC correction voltage to be applied to the clamping circuit to correct the blanking pulse or pedestal amplitude in response to the amount of light projected.

Abstract: An x-ray generator tube which includes an electron gun for directing a focused high energy electron beam toward an anode presenting an enlarged face inclined relative to the electron beam; with the tube having deflection coils for sweeping the beam across the enlarged anode face producing a moving focal spot. The tube envelope provides a shielded point-source window oriented with respect to the anode to pass only a thin beam of the x-rays which are generated at the moving focal spot, thereby producing a sweeping beam of x-rays. The sweeping x-ray beam is directed through the subject to an x-ray sensitive video pickup tube which is similar to a TV camera pickup tube, and which includes a face plate having a mosaic of chemically treated globules sensitive to x-rays which produces an electric image corresponding to the x-ray image produced by the sweeping x-ray beam passing through the subject being x-rayed. This mosaic is scanned and the pickup tube produces a video output signal in a conventional manner.

Abstract: A ring assembly includes two side-by-side flat ring members of uniform rectangular cross-section each being split, with the confronting split ends having radially overlapping fingers to define a circumferentially sealing joint. The ring members are dimensioned to be received in a common piston groove with the ring members being non-rotatably coupled so that the joint of one member will always be rotationally spaced from the joint of the other to define an axial seal for the ring assembly. A non-rotational coupling is provided by an integral tab formed in one member and projecting transversely therefrom and received in a mating transverse recess in the other member, with the recess having a larger dimension than the tab to permit sliding movement of the ring members relative to each other within the groove. Two forms of tabs include a partially sheared and bent tab and a partially displaced shear plug.
