US Patent:

59576707, Sep 28, 1999

Filed:

Aug 26, 1997

Appl. No.:

8/920081

Inventors:

Gregory S. Duncan - Huntington Beach CA
Eric L. Forman - Rancho Cucamonga CA

Assignee:

Wilden Pump & Engineering Co. - Colton CA

International Classification:

F04B 4306

US Classification:

417395

Abstract:

A pump having a center section including an actuator housing and an air valve is arranged with air chambers to either side of the actuator housing. Diaphragms are associated with the air chambers to create enclosed cavities for alternately pressurizing and venting the air chambers. Pumping chambers are positioned outwardly of the diaphragms and assembled with intake and exhaust manifolds and one-way valves to pump materials with operation of the diaphragms. The actuator uses a pilot shifting shaft which is shuttled by movement of the diaphragms. An air valve is controlled by the pilot shifting shaft to control flow to and from the air chambers. Diffusers include outwardly tapered oblong holes with ports from the air valves. An expansion chamber surrounds the diffusers and a exit to a standard muffler provides a smaller cross-sectional area than the diffuser outlet cross-sectional area.

International Classification:

A61B 34/10
G16H 50/50

Abstract:

The present application describes computer apparatus and software programs useful to the field of corrective spinal surgery. The apparatus and software implement and facilitate methods for assessing the degree of balance and alignment achieved through corrective measures applied to the spine prior to completing a surgical procedure. The apparatus and software facilitate pre-operative planning and virtual testing of the corrective measures to be applied. The apparatus and software further facilitate intra-operative reconciliation with the pre-operative plan prior to completing the surgery.
