The present invention relates to apparatus and methods of vibration. In particular, the present invention relates to apparatus and methods of vibration for tooling in a structure, such as, for example, a fuselage. In one implementation, the tooling comprises at least two conductors that create a force to vibrate the media in the tooling, which improves the compaction of the media in the tooling and the extraction of the media from the tooling. Other implementations may be used for compaction and...

Damper having a cylindrical body defining an upper aperture for the passage of a coaxial load-supporting rod and having an open lower end closed by a plate. A viscous liquid fills the space defined by the body and the plate. The inner surface of the body is lined with a layer of an elastomeric material which is integral with the rod in its upper part and has a portion of reduced thickness which defines with the body a chamber for compensating for variations in volume of said space produced by di...

An improved vibration isolator for reducing the transmission of vibrations between a supported body and a body suspended from the supporting body employs a pair of rotatable inertial masses that are coupled coaxially by an elastomeric spring. Suspension cables are wrapped around the rotatable masses and connect the masses with the supporting and the suspended body. The manner in which the cables wrap around the inertial masses causes the masses to roll back and forth along the cables when a vibr...

A vibration furnace for treating loose dusting and poorly transportable materials at a temperature of up to 500.degree.C, made according to the schematic diagram of a vertical vibration conveyor with a chute attached to supports of a vertical bearing pipe with the help of brackets mounted to be movable radially and insulated electrically from the supports of the vertical bearing pipe by means of insulators; said chute is connected in an electric circuit as a heater. The proposed vibration furnac...

A motor of a vibration generator has a rotary output shaft whose revolutions are variable and include a range of revolutions having a lower and an upper limit. A first element constitutes a first imbalanced mass and is fixedly mounted on the output shaft for rotation with the same. A second C-shaped element constitutes a second imbalanced mass and straddles the first element and the output shaft, being displaceable relative thereto under the influence of centrifugal force in direction substantia...

A vibration densitometer having a strain gage pick-up to serve at least four functions one at a time or to serve two, three or four functions in any combination of two, three or four. The strain gage is bonded to or may embody a vibrating vane or body to be immersed in a fluid. The strain gage may be bonded to a vane with glass or an epoxy or other uniting agent. If glass is used, the densitometer may undergo unusually high temperatures and still perform reliably and accurately. The strain gage ...

An insulator against vibrations having two rigid members for connection respectively to parts of a system subject to vibrations. One of the rigid members is of flattened shape and an envelope of deformable resilient material connects the two members. A portion of the envelope has the shape of a cup and receives at its centre the other of the rigid members, the envelope being filled with a high viscosity material.

Vibratory thrust is generated by a rotating crankshaft and controlled orbital movement of a single weight pivoted to the crankpin of the crankshaft. As the crankshaft rotates the center of gravity of the weight moves back and forth on a vector through the crankshaft axis. The direction of the vector is adjustable within a substantial angular range about the crankshaft axis.

A vibration densitometer having a temperature compensated probe.
