Inventor: BLANCH JOHN F
IPC: B29C48/92
Filed: 1989-05-25
Abstract: On-line rheological measurements are made utilizing a rheometer (20) of the type in which a first metering pump (24) delivers diverted melt from a process main stream to a capillary passage (30) and a second metering pump (34) returns the diverted melt from the capillary passage (30) to the process main stream and the viscosity of the diverted melt is measured by controlling the rate of flow of the melt to maintain constant the pressure drop between spaced apart locations along the capillary passage (30) and measuring the temperature of the melt in the capillary passage (30). The measurements may be made while controlling the speed of the second metering pump (34) independent of the speed of the first metering pump (24) to maintain the pressure at the exit (66) of the capillary passage (30) essentially constant. The capillary passage (30) is placed in close proximity to the process main stream for maintaining a relatively short residence time during which the diverted melt resides outside the process main stream so as to attain a relatively quick response to changes in the measured viscosity. The rheometer (20) includes a relatively thin plate interposed between first and second blocks, the plate including a slot establishing a chamber between the first and second blocks for providing the capillary passage (30).

Abstract: A process and apparatus for the recovery of oil from aqueous oil refinery waste involves mixing the waste with a fluidizing oil and evaporating the water from the mixture in a plurality of stages. The dewatered mixture is fed to a delayed coking system in which a conventional coker feedstock is being used. The heavy hydrocarbon portion of the dewatered mixture changes to coke and light hydrocarbon material, the inert solids become trapped in the coke, and the fluidizing oil vaporizes. A stream of heavy coker gas oil is fed from a fractionator in the delayed coking system to a fluidizing tank where it is mixed with the sludge to define the fluidizing oil. Another hot stream of hydrocarbon material from the coker fractionator is sent to the evaporator section to provide the heat for evaporation.

Abstract: In a color image signal evaluating apparatus and method, a color image signal corresponding to each pixel position on a display screen is converted by a color signal converter to an I signal and a Q signal, which are stored, as pixel data, in first and second image memories (13A, 13B), each at an address corresponding to the pixel position. The I signal and Q signal read out of the first and second image memories (13A, 13B) are differentiated by first and second differentiators (14A, 14B), respectively, with respect to the directions of pixel arrays to thereby obtain an I-signal differentiated value and a Q-signal differentiated value at each pixel position. A vector-composed value of the I-signal differentiated value and the Q-signal differentiated value at each pixel position is calculated and is stored in a third image memory (16). An evaluation part (17) represents, as a factor of the degree of a color reproduction error, the magnitude of a change in the differentiated vector-composed value stored in the third image memory and compares the factor with a fixed value, thereby determining whether or not the color reproduction error is within a given limit range.

Abstract: The amount of light coupled to an optical fiber (15) from a laser diode (11) is limited to a predetermined maximum power. A lens (30) receiving the laser output is adjusted to maximize the power received at the core portion of the fiber endface (17). The power coupled to the fiber is then reduced to the predetermined power level by insertion of a polarizing or absorbing filter (39) in the optical path. When a polarizing filter is employed, it is rotated until the predetermined power is coupled to the fiber. If a quarter wave plate is included, negative effects due to back reflections from the fiber end face into the laser diode can be eliminated.

Abstract: An object of the invention is to provide a method of expressing continuous gradation using a light writing type ferroelectric liquid crystal light valve. When the input image has gradation, the image that is written is converted into a binary form according to the pulse threshold possessed by the light valve and stored. When a voltage on which a DC voltage (2) is superposed is applied, on the other hand, the DC voltage is strongly coupled with the spontaneous polarization of the ferroelectric liquid crystal, and the state where molecules are turned in the direction corresponding to the polarity of the DC voltage becomes very stable but molecules directed in the direction of the opposite polarity are instable. Therefore, when the polarity (4) of the pulse voltage or the rectangular-wave voltage is selected to be opposite to that of the DC bias voltage at the time of writing and when the voltage level is set to a suitable magnitude, the liquid crystal molecules are turned along the cone at the time of writing using light and the turning angle is continuously controlled depending upon the intensity of write light making it possible to express the image having gradation.
