An apparatus for applying a thermoplastic powder to internal threads of a fastener includes a vacuum nozzle having an end adapted to engage a first surface of the fastener. A spray tube is sized to be inserted within the bore of the fastener and communicates with a source or sources of thermoplastic powder and pressurized air. A bushing is mounted on the spray tube so that the spray tube is able to slide with respect to the bushing. The bushing is adapted to engage a second surface of the fastener. The spray tube and bushing are movable between clamping positions, where the vacuum nozzle and the bushing engage the first and second surfaces of the fastener, and release positions where the vacuum nozzle and the bushing do not engage the first and second surfaces of the fastener. A fastener holder holds the fastener between the vacuum nozzle and the bushing so that when the vacuum nozzle and the bushing are in the clamping positions, the spray tube enters the bore of the fastener and sprays thermoplastic powder on the internal threads of the fastener with excess thermoplastic powder collected by the vacuum nozzle. The vacuum nozzle and bushing may be machined and to permit either, both or neither of first and second chamfers of the fasteners to also be coated.

A method of improving a structure of a component adjacent a feature is provided including removing a portion of the structure including at least one area where damage of corrosion has occurred or is likely to occur to expose a surface of the structure. A masking plug is installed into the feature such that a base of the masking plug is coupled to a first portion of the feature and a head of the masking plug is arranged adjacent a second portion of the feature. A structural deposit is formed on the surface and is integral with the structure. Excess material of the structural deposit and a portion of the head of the masking plug is removed. The second portion of the feature is reformed and the masking plug is removed from the feature.

A device for spraying a liquid for use in dye penetration inspection into an inner cavity of a workpiece for making a turbine engine part, the device including a workpiece support, a manifold for spraying the inspection liquid into the inner cavity, a manifold for sucking up and discharging the sprayed inspection liquid, and a mechanism for tilting at least a portion of the support from a substantially horizontal position to an inclined position in which the workpiece is inclined so that the inspection liquid sprayed into the cavity flows under gravity to a zone from which it is sucked up.

A wet/dry sheet dispenser. The dispenser has an elongate refill which holds a liquid and fits into a complementary base. Liquid is selectively dispensed from the refill by longitudinal activation of a pump. The pump may be disposed on either the refill or base. Liquid flows from the refill, upwardly to a dispensing cup. The user may then, optionally, take a sheet and wet it with liquid from the cup at the point of use. This arrangement allows for convenient and selective one hand pump operation, so the other hand is free to grasp the sheet. The sheet may be used wet or dry as desired at the point of use.

A workpiece processing arrangement comprises a spray booth (2) defining a work space (21), and operable to provide a controlled environment for spraying of material, a first oven (4) located adjacent a first end of the spray booth, the first oven defining an internal zone, and a second oven (5) located adjacent a second end of the spray booth, the second oven defining an internal zone (51). The arrangement also includes a transport rail (6) which extends from the internal zone (41) of the first oven (4), through the work space (21) of the spray booth (2) into the internal zone (51) of the second oven (5), the transport rail (6) being adapted for transport of a workpiece (10) between the work space (21) of the spray booth (2) to the internal zone of the first or second oven (4, 5). A corresponding method of processing a work piece in such an arrangement indicates the steps to be used when processing a first and a second workpiece The ovens may have both a baking and a curing zone. A ventilation system with an air curtain (23) may be included.

The invention relates to applying a liquid to pasty hot-melt adhesive to a substrate (44), comprising a template (29), having at least one cavity (38) for the hot-melt adhesive, and also comprising an adhesive-transfer infeed (33), which is assigned to the template (29) and through which the adhesive can be introduced into the cavity (38). The special feature consists in that the apparatus (10) further comprises a transporting-fluid-supply opening (35), assigned to the template (29), and a device for displacing (13, 15), in particular pivoting, the template (29) between a first position, in which the cavity (38) is assigned to the adhesive-transfer infeed (33), and a second position, in which the cavity (38) is assigned to the transporting-fluid-supply opening (35), and therefore the adhesive, in the second position, can be discharged from the cavity (38) by a transporting fluid flowing through the transporting-fluid-supply opening (35).

For allowing an access to an eye during a rinsing process it is suggested to configure an eye opening device in such a way that the eye opening device comprises two wing-like spreading elements for pulling the upper eyelid and the lower eyelid of the eye apart so as to support the opening of the eye during a rinsing process, wherein two access gaps are formed laterally between the two wing-like spreading elements of the eye opening device.

A method and apparatus for protecting a structure. A surface of the structure may be identified from a model of the structure. A perimeter of the surface of the structure may be identified from the model. The perimeter may be identified for the surface of the structure to be covered by a masking system during painting of the structure. A two-dimensional representation of the masking system may be generated for the structure based on the perimeter of the surface of the structure. Features for the masking system may be generated within the two-dimensional representation. Identifiers may be assigned to the features in the two-dimensional representation. Instructions for a forming tool may be generated based on the identifiers. The masking system may be formed from a sheet of masking material using the forming tool based on the instructions.

A high pressure surface cleaner includes a housing having an open end, a high pressure coupling in fluid communication with the housing and having a first end and a second end, the first end configured to receive a high pressure water source, and a supply conduit rotatably secured to the second end of the high pressure coupling and configured to rotate about the high pressure coupling defining a horizontal plane within the housing. The cleaner also includes first and second nozzles having a vertical axis therethrough and secured proximate to the first and opposing second ends of the supply conduit, respectively, the vertical axis of the first and second nozzles approximately normal to the first horizontal plane, and a directional nozzle coupled to the supply conduit and having a directional outlet orientated to cause the supply conduit with the first and second nozzles to rotate when discharging water.

An organic layer deposition apparatus, and a method of manufacturing an organic light-emitting display device using the organic layer deposition apparatus. The organic layer deposition apparatus includes: an electrostatic chuck that fixedly supports a substrate that is a deposition target; a deposition unit including a chamber maintained at a vacuum and an organic layer deposition assembly for depositing an organic layer on the substrate fixedly supported by the electrostatic chuck; and a first conveyor unit for moving the electrostatic chuck fixedly supporting the substrate into the deposition unit, wherein the first conveyor unit passes through inside the chamber, and the first conveyor unit includes a guide unit having a receiving member for supporting the electrostatic chuck to be movable in a direction.
