Patent number: 8861097Abstract: Optical lens attachments and cameras are disclosed. The attachment comprises a coupling mechanism for mating engagement with at least one of a camera and an optical lens. A barrel is coupled at one end to the coupling mechanism. A negative lens unit is coupled to the other end of elongated barrel. A diopter lens is disposed between the barrel and the coupling mechanism. The coupling mechanism, the diopter lens, and the barrel are aligned with an optical axis. Also disclosed is a double swivel optical system, comprising a negative lens unit, a mirror oriented at an angle to the optical axis of the negative lens unit, a roof prism for rotating incident light rays by 90 degrees and inverting an image, a rotation mechanism permitting rotation of the negative lens unit about a vertical axis, an image rotator comprising a prism that can invert an image, the prism disposed within the image rotator, and another rotation mechanism permitting rotation of the roof prism about an optical axis of the image rotator.Type: GrantFiled: December 23, 2012Date of Patent: October 14, 2014Assignee: FM-Assets, Pty LtdInventor: James Albert Frazier

Publication number: 20120134018Abstract: Wide-angle, deep-field, close-focusing optical systems are disclosed. According to one aspect, the optical system comprises a negative lens unit and a relay lens. The negative lens unit accepts radiation from an object in space. The relay lens is coupled to the negative lens unit. The negative lens unit and the relay lens are aligned on an optical axis in that order. The negative lens unit forms a first image on the relay lens to form a final image at a final image plane at a distance from the relay lens. The relay lens may comprise a zoom lens or zoom lens components, which may be movable.Type: ApplicationFiled: February 6, 2012Publication date: May 31, 2012Inventor: James Albert Frazier

Publication number: 20090116118Abstract: Lenses comprising first and second walls defining a cavity therebetween, which contains a fluid, are described. At least one of the walls is flexible, and the amount of fluid in the cavity can be changed to alter the shape of the at least one flexible wall, so as to alter the power of the lens. One or more flexible walls may have at least one groove formed in the wall(s) close to the periphery(ies) of the wall(s). In yet another configuration, the flexible wall and the second wall are bonded, welded, or fused together. In yet another configuration, a lens comprises a flexible wall and a second wall. The flexible wall is resilient and thinner in its central region, which is capable of being displaced relative to the second wall. Also described are methods of manufacturing a flexible wall for a lens.Type: ApplicationFiled: June 20, 2006Publication date: May 7, 2009Applicant: GLOBAL BIONIC OPTICS PTY LTDInventors: James Albert Frazier, Peter Denison Parks

Patent number: 4344548Abstract: Pump dispensers dispense liquids from the interior of a container without the need for removing the top. The pump dispenser employs a manually operated disk to which a diaphragm is attached to force air from an air chamber into the container interior where it displaces the liquid contents forcing them up a fluid tube and out a spout. A valve seals the air chamber except during pumping to prevent the entry of liquids into the air chamber.Type: GrantFiled: September 26, 1980Date of Patent: August 17, 1982Assignee: Aladdin Industries, IncorporatedInventor: Albert A. Frazier

Patent number: 4251252Abstract: A vacuum insulated container is constituted by a double-walled receptacle wherein the space between the walls is substantially evacuated to provide vacuum insulation. The outer wall is provided with an opening therein which is used during manufacture to provide access to the space between the walls so that the space may be evacuated. A stopper- or plug-like portion fills the opening after the container has been evacuated and is permanently joined or bonded to the surfaces of the opening thereby providing a sealing to maintain the vacuum in the space between the walls.Type: GrantFiled: June 23, 1978Date of Patent: February 17, 1981Assignee: Aladdin Industries, IncorporatedInventor: Albert A.

Patent number: 4113147Abstract: A vacuum bottle includes a pump dispenser for dispensing liquids from the temperature insulating interior without the need for removing the top or pouring. The pump dispenser employs a manually operated disk to pump air from a diaphragm into the bottle interior where it forces the liquid contents up a fluid tube and out a dispensing spout. A plurality of spaced ribs improve the operation of the dispenser mechanism by preventing twisting of the disk during pumping.Type: GrantFiled: September 29, 1977Date of Patent: September 12, 1978Assignee: Aladdin Industries, IncorporatedInventors: Albert A. Frazier, Howard W. Phillips

Patent number: 4089534Abstract: A packing assembly for location within a groove in one of a pair of relatively movable members comprises a deformable seal member having sealing lips engaging with the base wall of the groove and the surface of the other member, and a pair of support members. One or both side faces of each support member are provided with leakage grooves to enable fluid under pressure which collects in the zone defined between the support members, to be dissipated.Type: GrantFiled: June 16, 1976Date of Patent: May 16, 1978Assignee: Polypac B.A.L.
