Filed:

Jan 31, 2002

Appl. No.:

10/062592

Inventors:

Brady P. Ballman - Loveland OH
Daniel Ferris - Cincinnati OH
Stephen C. Mitchell - Mason OH
Jeff Pielage - West Chester OH

Assignee:

Rotex, Inc. - Cincinnati OH

International Classification:

B07B 142

US Classification:

209320, 2093651, 2093654

Abstract:

A screening machine of the type used to separate or classify mixtures of solid particles of different sizes includes a fixed base and a perforate screen deck mounted for movement relative to the base during a screening operation. Leaf springs connect the tail end of the screen deck to the fixed base so that the leaf springs support the tail end of screen deck for movement relative to the base. The leaf springs are oriented horizontally to avoid introducing vertical movement to the screen deck as it moves to and from the head and tail ends. The leaf springs are offset or deflected when the machine is at rest or in the neutral mid-point of its stroke. This arrangement advantageously utilizes the bias of the leaf springs to accelerate, assist or enhance movement of the screen deck during portions of its stroke and likewise to decelerate, hinder or retard the movement during other portions of its stroke. With an appropriate offset, an increase in the effectiveness of the screening process (i. e. , fewer defective particles passing through the screen deck) while a decrease in the screening time is attained.

International Classification:

F16F 1504

US Classification:

26714013

Abstract:

In a duo-pumping hydraulic mount, two acting pistons are employed, one associated with each working chamber. The pistons are rigidly connected. During operation, internal pressures generated in each chamber are opposite in sign with one being negative and the other being positive. Therefore, to achieve a given pressure differential across the fluid track, the magnitude of the pressure in each working chamber is half what would be experienced in a conventional single pumping mount. Durability is improved by reducing internal pressures and by distributing kinetic loads to two rubber elements so that individual stresses are minimized. An individual load bearing element supports static loads on the mount.

International Classification:

F16F 500

US Classification:

26714011

Abstract:

A hydraulic mount includes a mounting plate and a wall, with a working chamber defined between the mounting plate and the wall. The mounting plate and the wall are separated by a relatively thick elastomeric element so that the size of the working chamber varies as the elastomeric element is compressed and expanded by operation of the mounting plate and the wall moving closer together and farther apart. A reservoir is defined substantially by the elastomeric element in combination with a relatively flexible diaphragm that extends between the mounting plate and the wall so that the reservoir is generally annular in shape and is positioned around the working chamber. The elastomeric element serves as a separation wall between the working chamber and the reservoir. The mount includes a fluid track extending through the wall and opening between the working chamber and the reservoir, with a fluid contained in the working chamber, the reservoir and the fluid track, so that the mount is tunable by varying the size of the fluid track.
