  • Patent number: 8634051
    Abstract: A hurricane and tornado surface wind pattern disrupter and vehicle barrier has carbon steel plates, each mounting plural used tires. Tires are connected to opposite sides of the mounting plates with bolts, washers and nuts. The bolts extend through sidewalls of the tires or through gripper strips in slots in the plates. Ends of gripper strips hold the tire walls against the plates. Clamps connected to the bolts engage inner walls of the tires and hold the tires against the plates. Lateral edges of the plates are positioned inward from the tires. Downward extensions of the mounting plates are connected to fixed reinforced structures. When the plates are connected to tops of lane dividing jersey wall sections, the plates and tires assemblies form a continuously interrupted wall or ribbon for interference with strong surface wind patterns and for disruption and diminution of the wind forces.

  • Patent number: 4669865
    Abstract: A cooling device is provided for a light source in a copying machine, wherein the generation of air seemingly waving due to heat is prevented by effectively cooling a lamp body for lighting an original effectively in order to obviate the deterioration of an optical image.Light pervious heat-shield members are disposed at suitable intervals in an irradiation opening of the lamp body accommodating light source bulb and a reflector therewithin so as to enable blowing of ambient air past and between these members. At least the member positioned at the side of the light source bulb is composed of a heat-ray absorption glass. Air flow is guided through the chamber accommodating the light source bulb so that it may perform a forced air cooling of the inside of the lamp body in order to prevent the generation of the air waving due to heat from the lamp.

  • Patent number: 4093366
    Abstract: A motion picture projector is provided with a high intensity projection arrangement for improved image projection that also provides a projection lamp having a longer operating life. The projector is interconnected to a power supply unit by a multiconductor umbilical cable to supply all voltage and power requirements of the projector.The power supply unit is enabled to supply a high voltage starting pulse to the high intensity projection lamp only upon the occurrence of predetermined conditions to prevent shock hazards. The enabling control of the power supply is accomplished by the use of a standard projector control switch and a housing interlock switch on the projection lamp arrangement. Further, the power supply unit is enabled only when the umbilical cable is properly connected between the projector and the power supply unit by means of a return path continuity detector.
