  • Patent number: 4302697
    Abstract: The invention relates to automobile sealed-beam headlamps in which a reflector and lens assembly are hermetically sealed by an epoxy resin. A pressure relief hole in the reflector eliminates the problem of excessive expansion and contraction of the atmosphere within the lamp such as would prevent forming a hermetic seal between the reflector and lens during the epoxy resin curing cycle. A deformable metal pellet forms a hermetic seal in the pressure relief hole. An epoxy resin is applied over the deformable metal seal and cured to produce a final permanent seal.

  • Patent number: 4252379
    Abstract: A pressure control valve for use in vehicle hydraulic diagonal split brake systems. The valve includes two valve pistons which operate to limit the fluid pressure delivered to the rear wheel brakes relative to that delivered to the front wheel brakes. The valve also includes a failure warning mechanism having a switch actuating piston. In the event of a failure in one branch of the diagonal split brake system, the switch actuating piston operates to simultaneously preclude the two valve pistons from limiting the rear wheel brake pressure so that the rear wheel brake in the unfailed branch of the brake system can develop the maximum braking effort for vehicle emergency braking.

  • Patent number: 4240258
    Abstract: A master cylinder including a housing having a fluid reservoir and a cavity. A first piston is movable in the cavity. A sealing member is positioned for movement with the first piston. A fluid chamber is formed in the cavity ahead of the first piston. A second piston is movable within the first piston into and out of sealing engagement with the sealing member to close and open, respectively, a fluid path between the fluid reservoir and the fluid chamber.

  • Patent number: 4232908
    Abstract: A two knob control for tractor and trailer parking brakes providing single knob application of both tractor and trailer parking brakes. It also provides for maintaining the tractor parking brakes in the applied condition while charging the trailer brake air system and for applying the trailer brakes independently of the tractor brakes. Automatic application of trailer parking brakes is provided upon trailer breakaway or a significant reduction in tractor reservoir air pressure.

  • Patent number: 4223953
    Abstract: In a hydraulic brake system which combines a spring actuated, hydraulically released parking brake system with a hydraulically actuated service brake system and in which the parking and service brake systems both operate through a common force-transmitting element on the brakes, and in which the fluids in the two brake systems are mutually incompatible, an anti-compounding valve limits the sum of the forces which can be transmitted by the common force-transmitting element when the service and parking brake systems are simultaneously applied and which maintains the fluid in the two brake systems isolated from each other.

  • Patent number: 4224658
    Abstract: A rechargeable flashlight fits into and draws recharging power from an automotive type cigar lighter socket. A thermally controlled charging circuit within the flashlight adjusts the charging rate according to the ambient temperature. When the flashlight is withdrawn from the cigar lighter socket, it is illuminated; when it is replaced it is extinguished. Alternatively, the flashlight may be manually illuminated or extinguished outside the charging socket.
