  • Patent number: 4731886
    Abstract: A device for activating a rotating post, especially one that moves a swinging-door panel in a motor vehicle and which need no additional space at each end of the rotating post. The post is rotatably mounted in a mount at each end. The post is a hollow cylinder that accommodates a worm gear driven by a bi-directional pneumatic piston-and-cylinder drive. The piston-and-cylinder drive is completely accommodated inside the post and consists of at least two piston-and-cylinder units pneumatically connected in parallel with a common piston rod. Each unit incorporates a piston and cylinder aligned within a sleeve that is rigidly fastened to and coaxial with one of the mounts. The pressure medium that drives the panel in one direction is supplied to each cylinder through a coaxial bore in the piston rod. The bore extends axially and connects all the pistons. The bore communicates with the insides of the cylinders in the vicinity of each piston face that faces the same direction.

  • Patent number: 4730513
    Abstract: An electromechanical device for activating a rotating post that moves the leaf of a swinging door on a vehicle, especially a mass-transit vehicle. An electric motor activates the column by means of an intermediate worm gear. The motor outtake shaft is coupled to the worm-gear intake shaft. A worm wheel is coupled to the worm-gear outtake shaft, which activates the rotating post. The electromechanical activating device contains an emergency mechanism for uncoupling the worm-gear outtake shaft from the worm wheel in relation to their rotation. The mechanism incorporates a coupling that can be disengaged between the outtake shaft and the worm wheel, which is mounted over it coaxially. The mechanism also involves several balls situated such that they can be forced into recesses in the outtake shaft while simultaneously engaging axial grooves in the inner surface of the worm wheel.

  • Patent number: 4647645
    Abstract: Non-aqueous lacquer with high resistance to stone chipping, containing, as binder, a mixture of film forming, hydroxyl-containing copolymers with blocked polyisocyanates which have been obtained by the reaction of polyhydroxyl compounds containing 2 to 4 hydroxyl groups per molecule and having a molecular weight of from 400 to 2,000 with aliphatic and/or cyclo aliphatic diisocyanates, the ratio of isocyanate groups to hydroxyl groups being in the range of from 2.2 to 1.7, followed by reaction of the remaining free isocyanate groups with acetoacetic acid alkyl esters containing, as alkyl groups, methyl, ethyl, n-propyl, i-propyl, n-butyl, i-butyl or sec.-butyl groups, a process for its preparation, and its use.

  • Patent number: 4606947
    Abstract: Lacquer for coatings protecting against stone chipping, containing pigments, fillers, binders consisting of a mixture of film forming, hydroxyl-containing polyesters and aliphatic and/or cycloaliphatic polyisocyanates which are blocked with acetoacetic acid alkyl esters and have an average functionality of at least 2.5, organic solvents and conventional lacquer additives, which lacquer contains certain polyesters having an average hydroxyl functionality of from 2.5 to 6 and a hydroxyl content of from 2 to 6% by weight and containing from 15 to 50% by weight (aliphatic content) of aliphatic groups which have at least 4 to 20 carbon atoms in an unbranched chain, the proportion by weight of this aliphatic group content in the polyester to the benzene ring content in the polyester, calculated as the sum of the weight of carbon atoms of the benzene rings and of the hydrogen atoms attached to these carbon atoms (aromatic content) is from 1 to 2.5, and a process for its preparation and its use.

  • Patent number: 4409340
    Abstract: The invention relates to a heat-curable coating composition, comprising:(A) a prepolymer with ketoxime-blocked NCO groups, which are linked to the prepolymer via cycloaliphatic and/or aliphatic groups,(B) a diamine cross linker,(C) organic solvents in an amount of 0 to 50 weight percent, based on the total weight of the coating composition,(D) optionally pigments, fillers, blowing agents and other known additives.The equivalence ratio of blocked NCO groups of component (A) to NH.sub.2 groups of component (B) lies between 1.3:1 and 0.75:1. The invention also relates to processes for its application and its use. The composition has a long shelf life and is advantageously used as an impact resistive coating on metal substrates such as automobile parts.

  • Patent number: 4378656
    Abstract: An anti-clamping device for a vehicle door driven in opening and closing movements by a turnable shaft in turn driven by a transmission rod. The anti-clamping device comprises a telescopic element interposed in the transmission rod and including first and second telescopically engaged parts having retracted and extended positions. A control member is mounted on one of the parts and can be in the form of a projecting pin while spaced switches are mounted on the other of the parts. The pin projects between the switches to operate a selected one thereof depending on whether the parts are telescopically retracted or extended to reverse the direction of door movement. Thereby when an obstacle is present in the path of travel of the door, stress in the transmission rod will be accompanied by telescopic retraction or extension of the parts depending upon whether the door is in its opening or closing movement which produces closure of one of the switches to reverse the direction of door movement.

  • Patent number: 4376971
    Abstract: A system for protection against getting caught in automatically operable doors or windows, particularly of vehicles. Specific intervals of time within which the closing or opening door should reach a given position are preset. When the door does not reach one of these positions within the time allowed, the reversing motion is initiated or the cycle of motions is stopped. For this purpose, an electric signal generator coupled to the door motion delivers electric position signals when predetermined positions of the door are reached. An electric storage element is set by the position signals and after a predetermined time interval automatically reset, with the logic value of its output signal changing.

  • Patent number: 4322912
    Abstract: A safety device for a vehicle door of the type actuated by a turnable shaft driven by a piston cylinder unit having a piston rod connected by a hinge bolt to a lever arm fixedly mounted on the turnable shaft. The safety device comprises a carrier coupled to the lever arm and slidably receiving the piston rod, a switch element on the carrier and a control element on the piston rod. When the door encounters an obstacle, the control element is brought into contact with the switch element to reverse the direction of movement of the door.
