US Classification:

2224007, 222513, 2513352

Abstract:

A dispense head assembly comprise a housing, and a body having a fluid inlet and outlet attached to the housing. A piston is disposed within the body and housing and is attached at one end to an actuating handle. A poppet/diaphragm is attached to the opposite piston end and includes an imperforate head, a thin-walled sleeve that extends axially away from the head, and a tongue that defines a terminal edge of the sleeve and that forms a leak-tight interference seal with the body. The poppet/diaphragm sleeve is rolled between opposite piston and assembly wall surfaces to provide open- and closed-flow poppet/diaphragm movement. A dip tube adapter is releasibly attached to the housing and body. A tongue and groove seal arrangement is used to form a leak-tight interference seal therebetween. A dip tube is attached to the second adapter body end to provide fluid pick-up from a fluid container to the dispense head assembly.

International Classification:

F16L 5500

US Classification:

285 92, 285912, 285331, 285 81

Abstract:

Fittings of this invention comprise a body having a substantially hollow transport passage extending between a body first end and a body second end. The fitting body ends are adapted to accommodate attachment with respective fluid handling devices. The fitting has a hexagonal outside surface portion for grasping and rotating the fitting. An interlocking attachment member is disposed along an outside surface of the fitting body and is adapted to form an interlocking attachment with a complementary member of a fluid handling device when the fitting is connected thereto. The interlocking attachment member comprises a plurality of ratchet teeth that are configured to register with a complementary fluid handling device member. The fitting body first end includes a tongue that is configured to provide an interference fit within a groove in a fluid handling device opening to provide a leak-tight seal between the fitting the fluid handling device.

International Classification:

A47L 914

US Classification:

15352, 15347

Abstract:

A quick change, self-contained vacuum system includes a debris container with an input opening and a pressure head that is configured to receive a fluid under a high pressure and which includes a low pressure inlet and an exhaust port. A guide pin may be provided along with a body that is selectively engageable with the pressure head and the guide pin. The body includes a bore having a first port communicating with the exhaust port of the pressure head and a second port communicating with the input opening of the debris container. The vacuum system further includes a shutoff valve that is operable in response to movement of the guide pin. In operation, movement of the guide pin relative to the body in one direction establishes locking engagement of the pressure head and the body along with a response by the shutoff valve to establish fluid communication between the exhaust port of the pressure head and the input opening of the debris container. Movement of the guide pin relative to the body in another direction provides for separation of the pressure head and the body and response by the shutoff valve to prevent fluid communication between the first port of the bore and the input opening of the debris container.

US Classification:

408 1R, 408 56, 408 67, 408 72 B, 408 97, 408241 B

Abstract:

A high speed handheld power drill includes a housing with a motor, a chuck rotationally driven by the motor, and a drill bit clamped in the chuck. A pressure foot is mounted on the housing for coaxial rotation about the drill bit and lockable in a selectable angular position relative to the housing. A drill guide is slidably disposed within the pressure foot at an outer end thereof and biased for coaxial sliding movement between the drill bit and pressure foot. A vacuum cuttings pickup and coolant fluid delivery tool is coupled to the drill guide and arranged to deliver coolant fluid to the drill bit and to remove drill cuttings and coolant fluid and vapor therefrom during drilling. A coolant fluid reservoir is coupled to the drill motor housing and adapted to deliver selectably metered amounts of coolant fluid to the cuttings pickup and coolant delivery tool during drilling.

Assignee:

General Dynamics Corporation/Convair Div. - San Diego CA

International Classification:

B25B 2100

US Classification:

81 55

Abstract:

A tool for removal of round internally threaded collars from high efficiency aerospace fasteners. The tool includes a central cylindrical pin having a head at one end held against rotation, a non-round extension at the second end and a transverse bore intermediate the ends, containing a ball which is spring biased to project slightly beyond the pin wall. A mandrel assembly surrounds the pin and is rotatable relative thereto. A gripping collet is positioned between the mandrel and pin with collet fingers at one end extending beyond the mandrel and a threaded second end threaded into said mandrel. An axial slot in said collet is adapted to receive said ball when aligned therewith to form a releasable latch mechanism. In operation, the open collet fingers are placed over a threaded collar with said extension in engagement with a corresponding recess in the end of the bolt within the collar. The socket and mandrel are rotated in the collar unthreading direction.

Abstract:

A metal skin trimming device which cuts an edge of a first metal skin to a net shape that is complementary to the edge of a second metal skin that has been previously attached to a frame, such as the airframe of an aircraft fuselage. A guide carried by the device is adjustable to set the gap that will appear between the edges of the first and second metal skins when they are attached as by riveting to the airframe.
