  • Patent number: 4819370
    Abstract: A fan blows air and insects in the direction of the screen. A flexible monofilament rotates adjacent the screen on the opposite side of the fan. Lights within a box attract insects, and the fan draws the insects onto the screen. The rotating monofilament kills the insects and cleans the screen, and the insects remains are swept into circular gutters and fall into a collection drawer.

  • Patent number: 4466196
    Abstract: A laser alignment system for vehicles includes a laser module for attachment to either the front or rear wheels of a vehicle, a sensor module for attachment to the other wheels of the vehicle, and a control module connected to the laser module and the sensor module. Both the laser module and the sensor module can be attached to wheel spindles by the use of magnets, thereby eliminating rim adaptors and speeding set-up time. The modules are movable relative to the spindles and to each other so as to correct for vehicle uneveness, frame damage, and non-level floors. An electro-mechanical pendulum included as part of the sensor module provides fast, accurate caster and camber readings on a continuous basis for each wheel. The sensor module provides continuous, optical readouts of toe-in and toe-out for each wheel.
