Patent number: 4919403Abstract: Disclosed is a new basic type of extension or compression spring that can be made from thin or heavy strip stock, but yields spring strengths associated with much heavier and larger springs of currently used coil, leaf and other types. Additionally, the new spring provides a two or three spring constant response consisting of a first strong spring response, then a weaker spring response, then (if desired) a strong spring response. The variable rate is controllable by design, and no new technology is required to make springs with a very wide spectrum of strength and non-linear response. Anticipated applications range from a new type of hose clamp to direct reading torque indicators or automotive suspension springs.Type: GrantFiled: July 12, 1988Date of Patent: April 24, 1990Assignee: Proprietary Technology, Inc.Inventor: Donald D.

Patent number: 4897906Abstract: A fluid surge damper for damping fluid pressure surges in a fluid system. The damper including a housing and elastomeric element located therein which is protected from the deleterious effects of the fluid by a flexible membrane. The flexible membrane contains a subatmospheric pressure which draws the flexible membrane against the elastomeric element resulting in a partial compression of the elastomeric element. If the continuity of the flexible membrane is destroyed, the subatmospheric condition will equalize with ambient pressure conditions and the elastomeric element will expand to its original shape thereby providing a readily visual indication of a faulty unit. In addition, the flexible membrane may be sealed while containing a partial volume of liquid and the elastomeric material used may be liquid permeable, therein acting in combination to limit the physical deformation of the elastomeric material by defining a minimum volume to which the elastomeric material may be compressed.Type: GrantFiled: April 24, 1989Date of Patent: February 6, 1990Assignee: Proprietary Technology, Inc.Inventor: Donald D.
