Abstract: A method for determining the load exerted on the tire of a motor vehicle or to monitor the tire pressure, wherein during operation of the vehicle the pressure in the individual wheels is detected and the rotational behavior of the individual wheels is monitored, and wherein load distribution characteristic quantities are determined by comparing the rotational behavior or changes in said rotational behavior of the individual wheels during given driving conditions taking onto account preset or learned variables. Ultimately, the load exerted on the tires or pressure loss is determined from the tire pressure and the load distribution characteristic quantities.

Abstract: A flange for a device for separating an oil aerosol from air. This flange consists of a rubber-coated sheet metal and has the purpose of providing a seal between a housing and a mounting plate.

Abstract: An apparatus for forming a helical tube (18), including a first stamping station for producing a flange on a metal strip (11), a forming tool (17) in which the flanged metal strip is formed to a helical configuration and adjacent side edges are crimped together to produce a tube, a cutting arrangement (19) which cuts the tube into predetermined lengths, and a mechanical-optoelectronic measuring arrangement (20) for determining the length of the helical tube (18) to be cut.

Abstract: An oil separator for separating oil from oil-laden air has a housing, an inlet for oil-charged air to enter the housing, one or more coalescer elements arranged on a support body inside the housing, and outlets for the separated air and for the separated oil to exit the housing. Each end of the support body and a corresponding end of the coalescer element are fastened to a molded component. At least one molded component is in sealing contact with a sealing surface of the housing.

Abstract: An apparatus for separating an oil aerosol from air, including a separating element which is configured as an annular coalescer which coalesces the oil or oil mist in a known manner into larger oil drops which settle by gravity in the separating element and downstream therefrom. The separating element is disposed in a housing and fastened to a flanged piece, the flange piece including an adapter element to which additional flanged pieces and/or connecting lines for supplying and carrying away the air are attached.

Abstract: For controlling a traction slip control system with brake and motor management, motor regulating signals (m) are derived from electrical signals indicative of the brake pressure or which influence the brake pressure. Preferably, a brake pressure pattern (p[t]) is formed taking into account the pressure build-up and pressure decrease characterics of the wheel brakes or of the entire system as a basis for computing the motor regulating signals (m).
