US Patent:

41845668, Jan 22, 1980

Filed:

May 10, 1978

Appl. No.:

5/904392

Inventors:

Kenneth R. Baker - Woodland Hills CA
Robert T. DeVault - Simi Valley CA

Assignee:

Maritec Corporation - Canoga Park CA

International Classification:

F01N 114

US Classification:

181261

Abstract:

A noise suppressor for internal combustion engine exhaust, adapted for marine use wherein water coolant is discharged into the chamber of a single-walled riser and partially vaporized by the exhaust gases directed into the dome thereof for downward redirection and discharge from the lower portion of the riser chamber through a muffler element, and preferably through the hull chest and/or cover of a jet pump drive acting as the final noise barrier to atmosphere.

Appl. No.:

8/591888

Inventors:

Kenneth M. Baker - Van Nuys CA

International Classification:

G03H 110

US Classification:

359 10

Abstract:

A modulated index lens containing a subsurface zeroth order coherent microlenticular mosaic defined by an index gradient adds a normalizing function to the vergences or parallactic angles of incoming light rays subtended from field object points and redirects them, in the case of near-field images, to that of far-field images. Along with a scalar reduction of the lense's linear focal range, this results in an extreme depth of field with a narrow depth of focus and when used as an intraocular lens (IOL) or contact lens avoids the focal split-up, halo, and inherent reduction in contrast of multifocal IOLs and multifocal contact lenses. A high microlenticular spatial frequency, which, while still retaining an anisotropic medium, results in a nearly total zeroth order propagation throughout the visible spectrum. The curved lens surfaces still provide most of the refractive power of the lens, and the unique holographic fabrication technology is especially suitable for contact lenses, artificial corneas, and miniature lens elements for cameras and other optical devices. The holographic projector system has many other uses such as for the fabrication of directional light filters, microlens arrays, and highly corrected submicron patterning on curved surfaces.

8/381204

Inventors:

Kenneth M. Baker - Van Nuys CA

International Classification:

G03H 110

US Classification:

359 10

Abstract:

A photosensitive optical body is exposed by a diverging three-dimensional standing wave interference pattern generated by a holographic projector system. The projector system, using binary optics, creates a diverging lattice of hexagonal or square rod-like intensity maxima extending through the optical body. After the standing wave image is recorded and fixed, the optical body will contain a honeycomb-like grid or pattern that will cause either an absorption or a refractive index modulation effect on light that differs in incidence to the direction of normal propagation through the created channels to a focus or convergence point. This produces either a volume-absorption hologram or a volume-phase hologram (transmittance function modulated by the permittivity [index of refraction]) with such properties as depth of focus, high resolution, and a one-way (directional perspective) and anti-glare effect with reduced diffraction. Unique photosensitive aromatic diazo compounds which possess high thermal stability and soluble in non-polar solvents are provided. In the volume-absorption hologram, the compounds react with couplers within the optical body during development to form azo dye in the areas corresponding to destructive interference during exposure.

Appl. No.:

6/069740

Inventors:

Kenneth R. Baker - Woodland Hills CA
Robert T. DeVault - Simi Valley CA

Assignee:

Maritec Corporation - Los Angeles CA

International Classification:

B63H 1100

US Classification:

440 42

Abstract:

A reversible hydrojet boat drive for the substantially nonturbulent nozzling of water during the forward mode, and effective non jamming seal function during the reverse mode, and comprised of an exact nozzle continuation of the exit passage of the pump, particularly the top wall thereof, and the compatible eccentric relation of the surrounding seals of the reverse gate centered below the axis of gate rotation, thereby to avoid jamming and to eleviate strain on the control system therefor.

Appl. No.:

6/000591

Inventors:

Kenneth R. Baker - Woodland Hills CA
Robert T. De Vault - Simi Valley CA

Assignee:

Maritec Corporation - Canoga Park CA

International Classification:

B63H 1104

US Classification:

440 47

Abstract:

A hydrojet boat drive for efficient transition from low to high speed boat operation, characterized by a conventional drive pump unit and prime mover installation in the "slot" of a "V" bottomed hull and featuring a low drag ram-scoop with a blow-in door or panel which is responsive to imbalance between internal flow pressure and external slipstream pressure, whereby intake volume is augmented for low speed operation and ram pressures contained for high speed operation.
