Abstract: An automotive friction assist system with improved traction enables a motor vehicle to stop quickly and start easily on low friction surfaces, such as those present during icy conditions. The system operates by introducing more static friction points between the leading contact edges of wheels of a motor vehicle. Additionally, the present invention provides a sensor to activate the friction assist system when the road surface temperature is at or near the freezing point of water. The friction assist system will increase static friction on a road surface and aid an ABS system on a vehicle to bring the vehicle to a stop in less distance than otherwise possible. The friction assist system will also increase static friction and aid a motor vehicle's wheel slip regulator when a vehicle is attempting to gain traction or forward drive momentum.

Abstract: A sand dosing and blocking device for sand spreading systems for vehicles, particularly rail vehicles with drive, has a sand supply container with an outlet opening which can be closed by a closing element for the dosed release of sand to a conveyor unit which is preferably pneumatically activated. The closing element is formed by a lifting rod of an electrically activated lifting magnet. The lifting magnet is arranged inside the sand supply container in the area of the outlet opening. Frequency control of the lifting magnet varies the dosed flow of sand, which may be varied in response to vehicle wheel speed.

Abstract: A mudguard gritter that can be easily installed on trucks, school buses, delivery trucks and semitrailers. It can be fixed to supports of existing mudguards. The mudguard gritter comprises a container forming a hopper having the shape of a conventional aileron, with a top rectangular opening of 150 mm per 600 mm and a bottom opening of 25 mm per 600 mm. The top site has a door with hinges that make it possible to fill up the container with fine gravel. A rake supports eccentric vertical stems, which meet through an intermediate guide, at the bottom, on a mobile plate driven by a dual action cylinder powered by compressed air passing through a valve whose control is on the dashboard of the vehicle.

Abstract: A spreading device for confined application of grain type materials along a well-defined path on a road from a conveyor of a storing tank mounted on a moving vehicle includes a chute member mounted thereon that receives the materials from the conveyor and substantially drops them generally vertically under gravity on the road along the path in proximity and in front of a roller. The latter stops the materials relative to the road and confines, or packs, them on the road. The spreading device is adapted to be mounted on either side of the vehicle, in line with its wheels.

Abstract: An apparatus to improve traction conditions for motor vehicles under winter time driving conditions is disclosed. The invention comprises a sand storage reservoir and delivery system that supplies sand to each tire of a motor vehicle to aid in traction when driving in icy or snowy conditions found in wintertime driving. The sand reservoir provides sand to a plenum through four distinct sand compartments which dispense individual slugs of sand to a series of discs, connected via a cable, which move the sand through a delivery pipe to any of the four motor vehicle tires, as selected by application levers on the sand reservoir. The reservoir and associated controls are located inside the passenger compartment of the motor vehicle with the delivery tubes located on the undercarriage of the motor vehicle.

Abstract: An apparatus including a container directing a sand mixture through a plurality of conduits, a conduit associated with each drive wheel of an automobile through an intermediate valve body operatively opened by a cable mechanism. The organization is typically mounted within an engine compartment of an automobile. Further, the organization utilizes a nozzle head mounted at a terminal end of each conduit adjacent each wheel, with each nozzle head utilizing an apertured dispersion plate, wherein each aperture is selectively closed to define a selective width of path of sand directed adjacent each drive wheel of the automobile.

Abstract: A grit spreader for motor vehicles consists of a container (1) for the gritting material, a dispersion channel leading to a vehicle wheel and an endless conveyor (5). The conveyor (5) is disposed in a first horizontal section (2) of the dispersion channel and is divided into individual chambers (9) by transverse webs (8). The discharge end of the conveyor (5) lies above a second section (3) of the dispersion channel comprising the outlet (4) and which leads to the vehicle wheel and is closable by means of a flap (16). The drive unit (10) of the conveyor (5) is provided with a follow-up control which only stops the drive unit (10) following actuation of a cutout switch when a transverse web (8) of the conveyor (5) enters the upper return section (A) of the conveyor pulley (7) disposed at the discharge end.

Abstract: To ensure functioning and permanent readiness for operation of a sand-dispensing device for motor vehicles, which comprises a sand container and at least one sand channel with a sand outlet facing the wheel, two closing means are provided. The first one closes the outlet of the sand container, i.e. the passage into the sand channel, and the second one closes the sand outlet. The two closing means open simultaneously, so that the sand is discharged from the sand container directly onto the roadway. To stop dispersion, the outlet of the sand container is closed earlier, so that the sand channel can get discharged. Only then the second closing means closes the sand outlet of the channel and protects the discharged sand channel and the first closing means against humidity and mud.

Abstract: A pressurized air jet actuated swing valve for sandblasters is hinged with respect to the underside of the inverted head of the sandblaster to fit squarely against the sand filling opening in the tank head whenever the swing valve is maintained in closed position due to air pressure within the tank.
