Abstract: A feed and storage track which will hold DIP devices of three different widths in aligned rows, such as during treatment in an environmental chamber, and which will facilitate precise individual feed of the devices to a handling or testing station. The track has three rails with spacings to fit the three sizes of DIP devices straddling specific pairs of rails. A three pronged input head is adjustably mounted on one end of the track to feed DIP devices from a standard storage sleeve onto the appropriate rails.

Abstract: An adjustable flow rate nozzle for atomizing liquids comprises a tubular-like body for conducting a liquid under pressure having a discharge end terminating in a single plane surface, a structured device having a single plane surface which is attached with its plane surface contiguous with the plane surface of the tubular-like conduit and a slit-like aperature formed between the single plane surfaces of the tubular-like conduit and the structured device. The size of the slit-like aperture and thus the atomized flow rate is adjustable by securing structured devices to cooperate with the discharge end of the tubular-like body. The tubular body contains a main feed cavity of relatively large circular cross section and at least one corona cavity which is elongated outwardly from the main feed cavity. The corona cavity includes a pair of spaced sidewalls extending outwardly from the main feed cavity and an arcuate end wall joining the spaced side walls remote from the main feed cavity.

Abstract: An edge filter for a fuel injection nozzle is provided with an improved connection to the stem of the nozzle. The connection comprises opposed cylindrical guide sectors on the filter having axial knurls that extend less than the full length of the guide sectors thereon. The knurls, which are case hardened, provide secure interference interengagement with the softer counterbore of the nozzle's fuel inlet stem. The guide sectors advantageously provide an edge filtering function as well as a guiding function.

Abstract: A dual fuel injector has a body in which first, second and, optionally, third flow passages are provided. The first passage feeds liquid fuel to a first ring of outlet orifices which discharge into the second passage. The second passage leads to a second ring of outlet orifices which are aligned with orifices in the first ring and which are of greater cross-sectional area than the latter. The orifices of both rings lie on axes which are disposed at an acute angle (e.g. 45.degree.) to the longitudinal axis of the body so that a conical discharge of fuel and air is obtained in use. The second passage is an air passage when liquid fuel is being injected and may be an air passage or a gaseous fuel passage when the optional third passage is employed and the injector is in its gaseous fuel injection mode.

Abstract: In a jet pipe and variable area final nozzle assembly, the jet pipe 12 is necked at a region upstream of the final nozzle to reduce the diameter of the remainder of the jet pipe downstream of the neck to a diameter more nearly equal to but not less than the maximum throat area of the nozzle. The nozzle flaps are pivoted to the end of the jet pipe, although they could alternatively be translatable, and have an upstream portion 20 which overlies the jet pipe. An actuating mechanism preferably in the form of a unison ring 30 operated by jacks is mounted around the reduced diameter portion of the jet pipe and operates on the upstream portions of the nozzle flaps via a roller and cam arrangement 26, 24 to vary the area of the nozzle. An outer fairing 14 which now need be of no greater diameter than the maximum diameter of the jet pipe surrounds the jet pipe and the actuating mechanism (see FIG. 1).

Abstract: An actuation assembly for selectively varying the throat area of a convergent-divergent exhaust nozzle of a gas turbine engine and simultaneously achieving predetermined fixed ratios of throat area versus exit area. The assembly structurally comprises a plurality of constituent components (including a linear actuator member on the port side, and another on the starboard side, of the nozzle in parallel spaced-apart relationship with the centerline common to the engine and to the exhaust nozzle) that interact and cooperate to pivot the convergent flaps to reduce the throat area while simultaneously moving the divergent flaps inwardly, or to pivot the convergent flaps to increase the throat area while simultaneously moving the divergent flaps outwardly, as desired, thereby permitting the selective varying of the throat area while attaining a predetermined fixed ratio of the throat area to the exit area of the convergent-divergent exhaust nozzle.

Abstract: The invention contemplates a selectively operative flame-shaping feature in application to a powder-spraying gas torch, whereby directional jets of compressed-air or other pressure fluid may be discharged into angularly spaced off-axis regions of a developing flame spray, with selective rotational adjustment of the angular orientation of jet discharge with respect to the axis of flame-spray discharge.

Abstract: An electromagnetic fuel injector has an axially fixed guide pin for axial alignment of a spring biased, movable armature. The guide pin has an abutment shoulder thereon for engagement with a surface of the armature whereby to serve as an abutment stop so as to establish a predetermined minimum working air gap between the opposed working surfaces of the armature and an associated solenoid pole. A spring seat ring carried by an axially movable adjusting rod slidably received by a portion of the guide pin serves as an abutment for one end of the armature spring. An externally accessible abutment screw is used to effect axial displacement of the adjusting rod and therefor of the spring seat ring whereby to adjust the force of the armature spring.

Abstract: A hoisting and tipping construction, for emptying containers of different sizes, has two individual hoisting and tipping devices arranged side by side, which can be actuated either separately or else together and which are provided with individual pick-up structures each one of which is able to pick up a container to be emptied. Both of the pick-up structures are arranged so that they can simultaneously pick up a single large container. The individual hoisting and tipping devices are equipped with identical pressure-medium motors, connected to identical pressure-medium circuits that are interconnected at their feed lines, which lead from their individual control valves to the motors, through a shut-off or change-over valve that is able to connect the two pressure-medium circuits to each other as desired.

Abstract: The invention relates to a spray system for a multi-ingredient ablative material wherein a nozzle A is utilized for suppressing overspray. The nozzle includes a cylindrical inlet (12) which converges at (12a) to a restricted throat (13). A curved juncture (15) between cylidrical inlet (12) and convergent portion (12c) having a predetermined radius of curvature affords unrestricted and uninterrupted flow of the ablative material. A divergent bell-shaped chamber (14) and adjustable nozzle exit B is utilized which provides a highly effective spray pattern in suppressing overspray to an acceptable level and producing a homogeneous jet of material that adheres well to the substrate.

Abstract: An improved coal/air dispersion nozzle introduces fuel into the combustion chamber of a gas turbine engine as a finely atomized, dispersed spray for a uniform combustion. The nozzle has an inlet that receives finely powdered coal from a coal transport or coal/air fluidizer system and a scroll swirl generator is included within the nozzle to swirl a fluidized coal/air mixture supplied to the inlet of the nozzle. The scroll is in the form of a thin, flat metal sheet insert, twisted along its length, and configured to prevent build-up of coal particles within the nozzle prior to ejection from its outlet. Airblast air jets are included along the length of the nozzle body to assist in the discharge of the fluidized coal from the nozzle outlet and an angular pintle tip overlies the outlet to redirect coal/air mixture through a desired fluidized coal spray angle.
