Abstract: A ring-loaded flexural disc spring acts as an isolation mount in a thin cndrical space in the tail of a longitudinal vibrator type of underwater sound transducer. The ring-loaded spring comprises a thin disc having a raised bearing surface at a specified distance from the perimeter on one side of the disc and a raised bearing surface at the perimeter on the other side of the disc. The spring flexes into a concave shape when a load is applied. The operation of the disc is linear over the entire specified load range.

Abstract: An adjustable support system mounts one member, such as a textile spindle, on a second member, such as a textile machine rail, so as to reduce the transmission of vibrations between the two members. The support system incorporates a flange to which is secured an elastomeric element for resiliently mounting the textile spindle relative to the flange. The flange is kept spaced apart from the machine rail by a member or members that at least contact the flange and at least contact the machine rail. The spacing between the flange and the machine rail can be adjusted through manipulation of adjusting screws or bolts in such a manner as to change the orientation of the flange and the textile spindle mounted on the flange relative to the machine rail. Like the spacing member, the adjusting elements contact both the flange and the machine rail.

Abstract: A relatively quiet vibrating screen has a rotatable eccentric mass drive supported on the screen body by isolator mounts which transmit vibratory forces at shaker frequency unrestrained to the screen body and attenuate forces at higher harmonics of shaker frequency that would otherwise excite wall panels of the screen body into resonance, thereby reducing the noise level of the screen.

Abstract: A test stand for an internal combustion engine testing system is disclosed. The test stand permits the engine to substantially freely vibrate such that engine imbalance can be measured. The test stand includes a cradle and a support assembly, having a housing and an inflatable bladder member. The bladder member supports the cradle during the testing operation.

Abstract: A sound dampening fastening element includes a sound dampening body, an anchoring member and a support member. The dampening body is prism-shaped and formed of a resilient material. The anchoring member has a head and a shank with the head and a portion of the shank embedded within the dampening body and the remaining portion of the shank extending outwardly from the dampening body. The support member is partly embedded within the dampening body and the remaining part extends outwardly from the opposite side of the dampening body from which the shank extends. The support member has a shaped configuration with wall sections within the dampening body combining to form an opening through which the shank extends. The diameter of the opening is greater than the diameter of the shank but smaller than the diameter of the head of the anchoring member. The part of the support member extending outwardly from the dampening body includes openings for receiving a belt-like support element and also a threaded opening.
