Abstract: An electrical connector for testing of missile launch rail is provided. The electrical contacts of the connector move from a rear disengaged position to forward engaged positions via the energy of a compressed spring. The connector base has rail mounts for securing to a missile launch rail. A housing attaches to the base and houses a plunger, an insulator, electrical contacts, and a tube, which move forward and aft as a unit. A knob on a rear tube end enables user to limit the initial impact of the electrical contacts on contact pins or striker points of missile launch rail. The connector can provide electrical connection with launch rail pins as rail pins recede into the missile launch rail. Electrical contact position is governed, in part, by locating pins which ride in a track cut into an outer surface of the tube and move with rotation of an indexing ring.

Abstract: The wiring harness provided herein affords adjustability of the relative orientation between the connecting cable and its interface connector in real time, during field applications. The harness rotates to accommodate varying access angles to the desired test point connector. A cable conduit of the harness can be adjusted vertically relative to the axis of its interface connector, as well. Cable wire integrity is maintained during manipulations of the cable conduit relative to the harness electrical connector and stress on the wires is minimized. The harness can be sealed from moisture and environmental factors. The harness can provide shielding from electromagnetic interference for the cabling housed therein. The present harness is well suited for service in high heat environments in, for example, testing of aircraft systems. A cylinder receives the cabling conduit and swivels within a slotted backshell. Slot configuration can limit the translation of the cable conduit.

Abstract: Repeated inserting, tightening, loosening, and removing of external threads to internal threads can increase the likelihood of cross threading and thread damage. A spring loaded gear bolt assembly, which promotes alignment of mating threads before applying torque, is described. A spring is disposed on the back end of a bolt shaft to promote alignment of lead mating threads before twisting to engage external to internal threads. A gear chain translates a single hand rotation to thread two bolts into respective affixed internal threaded holes, simultaneously. A spring loaded gear bolt assembly and method described herein promote increased thread life and ease of use ease for test plate securing. Efficient single handed manipulation of multiple bolts simultaneously can be achieved using a test plate assembly, which included spring loaded gear bolt assemblies, as described herein. Applications of a spring loaded gear bolt include infrared adapter test plate assemblies.

Abstract: A conditioner roll includes a cylindrical, tubular metal core having four, straight metal flutes, in the form of channel members, extending full length of, and releasably attached to, the core. In one embodiment, each flute is attached by a plurality of bolts extending radially outwardly through and anchored in respective holes provided in the core, the bolts being respectively received in a plurality of holes provided in the flute. A nut is received on a threaded exposed end of each bolt so as to clamp the flute in place. Access holes are provided for permitting installation of the bolts. In a second embodiment, swage nuts are respectively anchored in mounting holes provided in the core for locating each flute, the nuts having been deformed axially, during installation of the flute mounting bolts, to form shoulders located interiorly of the core wall so as to that the nuts stay in place as the bolts are tightened against the flute.

Abstract: The reed employs two spaced apart cylinders with slots in their outer surfaces. The slots extend around the axis of each cylinder a given distance. The slots of each cylinder flare out from each other from one edge to an opposite edge. Dents are supported for movement between the two cylinders and have guides located in the slots of each cylinder. The two cylinders can be rotated together in one direction or in an opposite direction for causing the slots to move the guides and hence the dents apart or together to obtain changes in the width of the fabric along the warp direction. This change in width will cause the warp density to vary along the length of the fabric while maintaining continuous warp yarn. This feature also allows warp strands of different cross-section to be woven.

Abstract: A mobile machine for lifting massive objects which includes a primary hydraulic cylinder whose piston chamber is hydraulically connected on a high pressure end thereof to a high pressure end of one or more secondary hydraulic lifting cylinders for operation of the lifting cylinder(s) in unison to lift the object. The total maximum effective volume of the piston chamber(s) of the secondary cylinder(s) is at least equal to the maximum effective volume of the piston chamber of the primary cylinder. The sum total effective cross-sectional area of all of the secondary cylinder piston chambers is greater than the corresponding cross-sectional area of the primary cylinder chamber to provide an output lifting force of the secondary cylinder(s) which is greater than the input force applied to a piston rod of the primary cylinder necessary to transfer hydraulic fluid from the primary cylinder to the secondary cylinder(s) to produce the enhanced output lifting force.

Abstract: A trailer, for a header-equipped implement, has a T-shaped main frame, with the head of the T being defined by a beam extending in the direction of travel and with the stem of the T centered between a pair of loading ramps having first end portions coupled to the beam for pivoting about a fulcrum such that the ramps are moved from a loading to a transport position by the weight of the implement when the implement is backed up the ramps to a loaded position resting on the beam and in engagement with respective bumper/latch bars fixed to the beam. Stability of the trailer is maintained during loading of the implement by parking stands, at opposite ends of the beam, which are either manually or automatically moved between support and stored positions.

Abstract: A wobble drive for imparting reciprocating motion to a sickle bar includes a wobble drive shaft rotatable about a first axis and having a cylindrical wobble section formed about an axis making an angle of about 14.5.degree. to the first axis. A toroidal wobble shaft bearing housing is mounted on the wobble section by a set of wobble bearings having their outer races pressed into the bearing housing. An output yoke is coupled to the wobble shaft bearing housing for transmitting the oscillatory motion of the housing, caused by rotation of the drive shaft, to a swing arm fixed to an end of a shaft portion of the yoke. The coupling of the yoke to the wobble bearing housing is accomplished by a pair of headed spindle pins inserted, from the inside out, through pin bores provided at diametrically opposite locations in the wobble shaft bearing housing, and into respective yoke bearings mounted in the ends of a pair of yoke limbs that are joined to the yoke shaft portion.

Abstract: A drive for a center-pivot mower-conditioner includes a power shaft supported within the center-pivot tongue and ending in an equal-angle drive section which intersects the vertical axis of the connection of the tongue with the center of a transverse beam forming part of a main frame of the mower-conditioner when the tongue is in a straight ahead position. A multiple v-belt drive transfers rotation of the tongue-carried drive-line to a substantially horizontal, fore-and-aft extending main header drive shaft located just leftwardly of the transverse beam of the main frame. The main header drive shaft is coupled to a first header drive box containing right-angle gearing for directing power to a downwardly extending through shaft extending through a second header gear box to a left-most cutting unit of a rotary cutterbar extending transversely across a header suspended for floating over undulating terrain during cutting operation.

Abstract: A moth type rolling cutter drill bit has a plurality of rolling cutters mounted on legs, each rolling cutter having a back face portion and a gage face portion, and a high velocity fluid nozzle which directs a stream of high velocity fluid toward the cutter. Each cutter has a row of gage teeth to cut the gage of the borehole, and at least one of the cutters has a plurality of flow channels spaced apart around its gage face portion to provide fluid communication from the back face of the cutter and between and around pairs of adjacent gage teeth. Each flow channel is inclined at an angle to a radius of the cutter so as to be oriented towards the stream of fluid from the high velocity nozzle as the teeth adjacent to the flow channel engage the formation being drilled.

Abstract: A tool (400) is disclosed for use in recovering gas from a gas well without the production of water as well. The tool (400) uses a member, such as plurality of vertically stacked balls (430) which are lighter than water to close a channel 422 when the water level (432) exceeds a certain level. As gas accumulates about the balls, the water level 432 will be moved downwardly, eventually causing the balls to move out of engagement with the seal surface (424), opening the channel (422) for passage of the gas upwardly for recovery. As the water level rises, the balls will again seal against the seal surface (424).
