Patent number: 3969623Abstract: A flat-plate camera for X-ray diffraction studies of powdered materials under various conditions of temperature. A spindle assembly is provided for rotating a sample specimen about the longitudinal axis of the sample and such that the axis of an X-ray beam striking the specimen, orthogonally intersects the longitudinal axis of the specimen. The spindle assembly includes means for providing a temperature controlled air stream which is directed towards the sample specimen along its longitudinal axis for varying the sample temperature. A flat film plate to be exposed is vertically mounted in back of the sample specimen and is asymmetrically arranged with respect to the X-ray beam. An X-ray shield is provided to permit exposure of sequential segments of the film plate thereby providing direct comparison on one photograph of different exposures taken at various sample temperatures.Type: GrantFiled: January 10, 1975Date of Patent: July 13, 1976Assignee: The University of MississippiInventors: Theodore J.

Patent number: 3949224Abstract: An optical modulation system and frequency doubler utilizes an organo-substituted carborane cell sandwiched between a pair of crossed polarizers. Light passing through the cell is rotated an amount determined by an electrical control signal applied across the cell. Hence the amount of light passing through the system is modulated by the control signal. When the cell is modulated by an AC control signal, light modulation occurs at twice the AC control signal frequency since the cell has two possible orientations which permit maximum light transfer. The modulated light is directed upon an electro-optical transducer which produces an electrical output proportional to the intensity of the light impinging thereupon.Type: GrantFiled: July 17, 1974Date of Patent: April 6, 1976Assignee: The University of MississippiInventor: Theodore J. Klingen

Patent number: 3946953Abstract: A shaft is rotatably supported on both the ends of the housing. The housing has an inlet for charging discarded glass articles and an outlet for discharging glass fragments. Crushing bars are mounted on the shaft and arranged from near the inlet toward the neighborhood of outlet of the housing. The glass articles charged through the inlet into the housing are kicked by the crushing bars toward the inner surface of the housing and broken into fragments while being rebounded on the inner surface of the housing. The glass fragments dropped down onto the bottom of the housing are agitated, by poking bars mounted on the shaft in the neighborhood of the outlet, while being subjected to impact forces, to permit them to be reduced to substantially rounded gem-like granules.Type: GrantFiled: October 30, 1974Date of Patent: March 30, 1976Assignee: Nobutoshi OhuchiInventor: Kuniki Hato

Patent number: 3938974Abstract: Procedures are disclosed for producing both core-cladding optical fibers and self-focusing optical fibers from porous germinate and/or silicate glasses obtained after phase separation and removal of the soluble phase. A glass which is separable into at least two phases one of which is soluble, is heated to cause phase separation. The soluble phase is leached out removing undesired impurities. The pores are collapsed and this glass is used to produce cores and/or cladding layers, or self focusing fibers. According to one aspect of the invention, preforms of the porous glass have their interconnected pores stuffed with a dopant. In the production of core-cladding optical fibers, the dopant modifies the index of refraction of the core and/or cladding so that the index of refraction of the core is greater than that of the cladding. The control of this index of refraction can be accomplished by addition of non silicate network formers such as GeO.sub.2 to the original melt before phase separation.Type: GrantFiled: April 22, 1974Date of Patent: February 17, 1976Inventors: Pedro B. Macedo, Theodore A. Litovitz

Patent number: 3935972Abstract: Provided is an injection unit for the hot runner molding including a heating cylinder having passageways for fused plastic longitudinally formed therethrough and a nozzle member attached to one end of the cylinder and having an injection nozzle. Within the cylinder is fixably disposed a torpedo, which has a central blind hole formed therethrough in a manner spaced from and parallel with said plastic passageways of the cylinder. Within the central blind hole is disposed a spring assembly, which always biases a pin member abutting against the spring assembly. The pin member is provided with a valve and both are integrally operated. Where a prescribed level of plastic pressure acts on the valve, the valve is separated from the nozzle member to permit the plastic to be injected through the injection nozzle. Where the prescribed plastic pressure does not act on the valve, the valve is made to abut the nozzle member by the bias force of the spring assembly to close the injection nozzle.Type: GrantFiled: December 27, 1974Date of Patent: February 3, 1976Assignee: Fuji Plastic Co., Ltd.Inventors: Shiro Tsunemoto, Eiichi Hirayama, Teruki Mizuguchi
