  • Patent number: 5154662
    Abstract: A crab extractor including opposed, large cylindrical rollers oriented in vertically superimposed relation with the lower roller being perforated. Cleaned, uncooked crabs which have been broken along a longitudinal center line from front to rear along the bottom are fed between the rollers with the feelers first by a belt conveyor. The rollers are driven which forces crab meat through the perforations or holes in the bottom roller which is scraped off by a doctor blade into an ager which conveys the extracted meat to a point of discharge. The shell components of the crab are not forced through the perforations and are scraped off of both rollers by doctor blades onto a conveyor. The rollers are interconnected by large meshing gears at one end thereof in order to rotate both rollers at the same speed in opposite directions. The lower roller is driven which in turn drives the upper roller and the auger which conveys the extracted meat from interiorally of the bottom roller is independently powered.

  • Patent number: 5152633
    Abstract: To form a paved surface, a laminate is used which has on the bottom a geotextile fabric with the mesh structure on the top. The fabric is adhered to the road base by spraying or spreading a bituminous liquid onto the base and laying on the laminate and applying further adhesive to the top of the laminate; asphalt is then placed and rolled. The laminate is formed of a square or rectangular mesh structure which has oriented stands connected at junctions which are thicker than the strands and have low-orientated or unorientated nodules. On one side the surface of the nodules are melted and the fabric is pressed into the nodules so that the plastics material of the nodules envelopes some of the fibres or filaments of the fabric to form a mechanical bond. In this way, the oriented strands stand proud of the fabric, to enable the asphalt aggregate to penetrate into the meshes and interlock with the strands.

  • Patent number: 5152270
    Abstract: An engine control system for an internal combustion engine is equipped with dual air-fuel ratio feedback control systems for feedback controlling air-fuel ratios for two groups of injectors. The system includes a common air flow rate sensor, common to both groups, for detecting a common air flow rate introduced into the cylinders and an individual air-fuel ratio sensor for each group of injectors for determining an air-fuel ratio related value for its respective air-fuel ratio feedback control system. A feedback correction value for correction of fuel injection is determined from the air-fuel ratio ralated values for each air-fuel ratio feedback control system. An air flow rate is corrected based on the feedback correction values for correction of fuel injection for the dual air-fuel ratio feedback control systems. Virtual fuel injection rates for the two groups of injectors are then determined from the corrected air flow rate.

  • Patent number: 5153751
    Abstract: The invention relates to a holographic display element which includes a reflection hologram and is attached to, for example, an automobile windshield so as to project light rays carrying images of display information onto the display element from a luminous source in the car. When external light such as sunlight coming is diffracted by the reflection hologram there is a possibility that visible light ranging from 570 nm (greenish yellow) to 780 nm (red) is diffracted into a certain range of angles in a horizontal plane and makes a strange impression on persons viewing the windshield from the outside. According to the invention another reflection hologram having different diffraction characteristics is superposed on the first hologram on the outer side in order that diffraction of visible light into the aforementioned range of angles may become inconspicuous.
