Filed:

Jan 14, 2008

Appl. No.:

12/013930

Inventors:

Zbigniew J. Orzelski - Bloomfield Hills MI, US
David Michael Masters - Troy MI, US

Assignee:

FORD GLOBAL TECHNOLOGIES, LLC - Dearborn MI

International Classification:

B60N 2/42

US Classification:

29721612

Abstract:

An active head restraint system for a vehicle seat includes a head restraint, force pad and connectors. The head restraint and force pad are connected via the connectors. The active head restraint system is connected with a frame of the vehicle seat such that rearward movement of the force pad results in forward movement of the head rest. Springs attached to the active head restraint system and a frame of the seat are used to resist the rearward movement of the force pad.

Appl. No.:

9/020773

Inventors:

Paul T. Gray - Laguna Hills CA
David R. Masters - Laguna Hills CA

International Classification:

C08J 932

US Classification:

523218

Abstract:

A foam of very small, microscopic bubbles of surfactant, each bubble containing a small quantity of water, is mixed with a water/cement mixture having a water to cement ratio of less than 0. 33. The small bubbles have a ball bearing effect on the smaller cement and sand particles, increasing plasticity or flowability and thus reducing the water requirements of the mixture. The foamed cement mixture is laid to form a desired concrete structure, and the bubbles disintegrate or transform to leave voids of similar size uniformly dispersed throughout the concrete structure.

Inventors:

Paul T. Gray - Laguna Hills CA
David R. Masters - Laguna Hills CA

Assignee:

Stable Air, Inc. - Laguna Hills CA

International Classification:

B01F 304

US Classification:

261 59

Abstract:

A foam producing apparatus has a first mixing chamber with an inner subchamber connected to a supply of gas at a first pressure and an outer subchamber connected to a supply of a foamable liquid at a second pressure higher than the first pressure. A plurality of orifices connect the outer subchamber to the inner subchamber. The foamable liquid is forced from the outer subchamber into the inner subchamber through the orifices and is atomized to form droplets carried by the gas to an outlet. A second mixing chamber is connected to the outlet of the first mixing chamber and is filled with an agitating medium so that droplets propelled through the second mixing chamber are violently agitated to produce the desired foam.

David MASTERS - Great Falls VA, US

International Classification:

G01N 1/02
G01N 1/28

Abstract:

Various embodiments directed to a work stand for holding a microscopic collection device for collecting a microscopic sample from a target surface, are provided. The work stand includes a first slit formed on a top surface of the work stand and capable of holding a first microscopic collection device comprising a first holding element and a first collection platform, wherein the first collection platform of the first microscopic collection device is perpendicular to the top surface. A second slit formed on the top surface of the work stand and capable of holding a second microscopic collection device comprising a second collection platform and a second holding element at an angle to the second collection platform perpendicular to the top surface of the work stand.

Assignee:

International Classification:

G01N 1/02

Abstract:

A microscopic collection device, method for collecting a microscopic sample from a target surface, and the work stand for holding the microscopic collection device are provided. The microscopic collection device includes a holding element comprising a handle at one end and a collection platform connected to the holding element at a second end. The collection platform includes a collection surface on which the microscopic sample is deposited when the microscopic collection device comes into contact with the target surface. A tape is inserted through a slit and wrapped around the collection platform. The work stand includes a slit capable of holding the microscopic collection device such that the collection platform is perpendicular to the top surface of the work stand. A microscopic sample, collected using the microscopic collection device, is not only collected from the target surface but is also concentrated onto the collection face of the tape. Removal of the collection face of the tape excludes excess tape that would disrupt downstream analysis of the microscopic sample.
