  • Patent number: 5316897
    Abstract: A method and apparatus for exposing a substrate of relatively large surface area to radiation according to a predetermined pattern recorded on a mask, particularly useful in applying a painted border to an automobile windshield, includes the steps of progressively recording the predetermined pattern on a mask in the form of a continuous strip, and moving the radiation source to progressively scan the surface of the substrate with radiation, while at the same time moving the continuous strip mask relative to the radiation source, such that portions of the pattern on the continuous strip mask progressively become aligned with their corresponding portions of the substrate as the substrate is progressively scanned by the radiation source.

  • Patent number: 5303632
    Abstract: A projectile propelling system includes a gun barrel filled with a gaseous propulsive mixture, a projectile having a front cone wall and a rear cone wall, and a driver for initially propelling the projectile in the gun barrel to an initial velocity above the detonation velocity of the gaseous propulsive mixture to produce a shock wave at the front cone wall followed by a detonation wave resulting from the reflection of the shock wave inside the barrel, which detonation wave is applied to the rear cone wall to increase the velocity of the projectile. The front cone wall and rear cone wall of the projectile are such as to create a "mach stem" in the form of a disc normal to the longitudinal axis of the projectile, of sufficiently high pressure and temperature to ensure ignition of the gaseous propulsive mixture.

  • Patent number: 5298719
    Abstract: A method and apparatus for concentrating the heat energy of a laser beam by directing the laser beam to an optical device, such as a planar mirror, located at a first focal point of a reflector having a curved surface approximating that of an ellipsoid. The optical device redirects the laser beam to the curved surface of the reflector which reflects and focusses it to a second focal point of the reflector. The optical device is driven to cause the laser beam to successively scan different portions of the curved surface of the reflector while the latter surface reflects the laser beam substantially to the second focal point where the object to be heated is located.
