Title: Side load compensating air suspension
Inventor: WARMUTH IVAN J II
IPC: B60G13/00
Filed: 1986-11-26
Granted: 1991-07-30
Abstract: Abstract of the Disclosure SIDE LOAD COMPENSATING AIR SUSPENSION     A vehicle suspension strut incorporating an airspring around a hydraulic shock absorber is disclosed.  The airspring design and orientation relative to the shock absorber axis creates a side acting force which counteracts the bending torque acting on the strut during operation in a vehicle and prevents binding of the shock absorber piston.  The horizontal acting side load can be achieved by using an airspring piston eccentrically mounted on the shock absorber.  Alternatively the airspring may be mounted offset and/or at an angle to the shock absorber axis.          The flexible membrane of the airspring may also be cut in a plane oblique to the shock axis and mounted on the airspring piston to form asymmetric rolling lobes about the circumference of the piston.

The inner housing projects at least partially beyond the front and rear walls of the outer housing in an assembled condition to form a pair of opposed, spaced-apart, cable receiving channels extending from the top to the bottom of the  inner housing for receiving opposed free ends of a length of high strength cable, the free ends having at least a portion thereof of a deformable nature.  Cable engaging and locking means are provided within the inner housing comprising an obliquely extending cam receiving surface and an opposed surface having a pair of spaced apart projections thereon, forming a cable receiving land portion between the spaced-apart projections.  The cable engaging and locking means have a top portion of a width greater than a bottom portion thereof.  Rotatable cable engaging cam means are adapted to ride on the cam receiving surface of the cable engaging and locking means opposite the cable receiving land portion; and stop means extend from the cable engaging and locking means.  The stop means prevent vertical movement of the cam means beyond a predetermined point in the inner housing. The seal of this invention employs fewer components while providing a high degree of security.

Granted: 1991-01-29
Abstract: IMPROVED COMMINUTER FOR SOLID MATERIAL   Abstract of the Disclosure An improved comminuting device for pulverizing solid material includes a comminuting chamber and a discharge chamber adjacent the com-minuting chamber. A screening assembly is located at the interface between the comminuting chamber and the discharge chamber and regulates the size of particles permitted to pass from the comminuting chamber into the discharge chamber. The screening assembly is adjustable to selectively vary the maximum size particles permitted to pass into the discharge chamber. Also, the comminuting chamber is defined by a series of rolls having abrading protrusions on their outer surfaces. The protrusions comprise teeth that are removably and replaceably mounted on the rolls for ease of repair and replacement. The teeth are held in slots formed in the rolls and are oriented so that the force of the material being broken down in the comminuter acts against the teeth to keep them within the slots. In one embodiment, the tooth is deformed as it is inserted into the slot and the tendency of the tooth to return to its original shape provides a biasing force against the walls of the slot to maintain the tooth within the slot.

Title: Fluid filled elastomeric damping device
Inventor: COAD L DALE
IPC: F16F13/00
Filed: 1987-07-20
Granted: 1992-05-26
Abstract: FLUID FILLED ELASTOMERIC DAMPING DEVICE                Abstract A fluid filled engine mount for absorbing shock and dampening structural agitation is provided in which an elastomeric diaphragm and an associated air chamber cooperate with a fluid filled chamber to allow high frequency, low amplitude structural agitation to the mount to occur with very little pressure developing in the fluid chambers and, accordingly, a slight damping response.  The fluid chambers are included within an elastomeric shear spring spacing a rigid outer housing including the diaphragm and air chamber from a rigid inner member.  The housing and inner rigid member are typically associated with an engine frame and engine, respectively.  The diaphragm is restrained against exces-sive deflection by an outer sleeve which comprises a restraint stop for the diaphragm.  Upon contact of the diaphragm to the outer sleeve, pressure is developed quickly in the fluid chambers which then activates either a tuned fluid resonance channel or a restrictive fluid flow path for dampening of the agitation.
