  • Patent number: 4286308
    Abstract: An improved glare control system for use on a vehicle for reducing headlight glare from oncoming vehicles, the system being of the type wherein the headlights are rapidly switched between light emissive and non-emissive states and the operator views the roadway through a visor operating in synchronism with the headlights and being switchable between light transmissive and opaque states, and wherein the improvement includes means for measuring the glare intensity of the oncoming path and providing a proportional glare level signal and means responsive to the signal for varying the transmissive-to-opaque interval ratio of the visor cycle so that at least between upper and lower glare intensity limits the apparent density of the visor increases with increasing glare intensity and decreases with decreasing glare intensity.

  • Patent number: 4047289
    Abstract: A method for forming a slurry cell electrode structure which serves as a component of a planar battery. The slurry electrode structure is formed in situ as a particulate dispersion of active material in aqueous electrolyte. The method utilizes a slurry precursor prepared by predepositing a liquid carried dispersion of the particulate active material over the surface of a select component, such as a separator, current collector, or intercell connector of the cell. This deposition is dried and prepared as a subassembly which is appropriately inserted within the multicell pile structure as a step in the manufacture of a multicell battery. By wetting the subassembly with a wash coat of aqueous electrolyte, in situ slurry formation is provided.
