  • Processes for the preparation of acid fortified paramagnetic iron sulfate salt compounds for use in the treatment of agricultural soils
    Patent number: 5129936
    Abstract: The formation of paramagnetic iron sulfate hydrate salts containing iron in the di- and trivalent states from black magnetic iron oxides of high iron content and their use as fertilizers effective on both acid and alkaline soils is disclosed. Such oxides are comminuted, wetted with a specified amount of water, reacted with concentrated sulfuric acid, and dried. The resultant products are paramagnetic and contain iron in both the di- and trivalent states. These products have fertilizing and soil conditioning properties superior to non-magnetic iron compounds containing iron only in either the di- or trivalent state.

  • Locking device and vehicle safety belt tightening apparatus
    Patent number: 5129679
    Abstract: A locking device for securing at least first and second members which are movable relative to each other in response to a force acting thereon, in a locked rest position, with a release mechanism for releasing the members from their locked position, includes a locking element providing at least first and second support locations at which respective ones of the first and second mutually relatively movable members bear against the locking element to hold them in a locked condition. The co-operation of the locking element and one of the mutually relatively movable members provides a pivot axis about which the locking element is pivotable under the effect of an unlocking moment, to provide a release action. The device further includes a stationary stop means against which, in the locked position, the locking element bears due to the unlocking moment applied thereto.

  • Fluororesin based coating composition applicable to plastic surfaces
    Patent number: 5130365
    Abstract: The invention relates to a coating composition suitable for application to plastic surfaces. The coating composition comprises, as essential components, 100 parts by weight of a chlorotrifluoroethylene based copolymer having hydroxyl group as a functional group, a curing agent for the copolymer such as a polyisocyanate, 0.5-30 parts by weight of an acrylic or methacrylic polymer which serves as an adhesion improving component, and an organic solvent. Usually the composition contains an ultraviolet absorber and another light stabilizer. For example, on a polycarbonate article this composition provides a durable coating film without marring the transparency and healthiness of the polycarbonate substrate. By the addition of a pigment the coating is modified into a paint composition which is particularly useful for repairing a bake finished paint film formed by using a polyvinylidene based paint.

  • Airfoil roof for vehicles
    Patent number: 5129699
    Abstract: An airfoil roof incorporated into or added onto a vehicle roof in the form of a longitudinal tunnel that is open at the front and closed at the rear which enables air to pass into the forward end of the tunnel during forward movement of the vehicle with the closed rearward end of the tunnel catching such air which causes a limited lifting force to be exerted on the vehicle to, in effect, reduce the weight of the vehicle thereby reducing the energy required to propel the vehicle over a road surface thereby resulting in energy conservation by enabling a vehicle to be propelled a greater distance while consuming a given quantity of fuel which results from the decrease in weight and the reduction in rolling resistance and fricitonal resistance between the vehicle tires and road surface.

  • Three-pole, gas-insulated switch arrangement
    Patent number: 5128502
    Abstract: A three-pole switch arrangement has for each pole a pole housing, onto which collar-shaped extensions, protruding on the underside, are formed. Provided in the extensions are screw holes, the graduation of which corresponds to the screw coupling, by which the mechanism housing has been screwed to the pole housing. The outer switch poles are oriented outwardly by one graduation and are fastened to the frame by means of screws. Counter to this inclined position, the mechanism housing, rotated by one graduation, is screwed onto the pole housing. It is consequently possible to use the same parts for all three switch poles, and also to transport the switch arrangement pole-by-pole.
