Abstract: In a filter unit (25) and apparatus for desludging salt baths (1), which is flooded at least partially by the salt bath and is in working association with the upper end of a riser tube (23), the bath fluid to be desludged being driven, by means of a compressed air stream, for example, through the riser tube (23) toward the filter unit (9, 25), the filter cloth packet is made of woven wire of a nonferrous metal, preferably an alloy based on aluminum, nickel or titanium, and is surrounded by a filter frame (14), the frame (14) being shaped into a shallow, pyramidal frustum-shaped funnel (18) pointing toward the bottom of the vat, its apical bottom end being provided with a closable opening (19).

Abstract: A wheel suspension for an axle of a motor vehicle has a transverse control arm and tension strut, the transverse control arm being held on the wheel carrier by way of a joint, and the body-side bearings of the transverse control arm and of the tension strut as well as of the connection bearing between the transverse control arm and the tension strut being constructed with a defined characteristic for the elastokinematic adjustment of the wheel under the effect of lateral and peripheral forces acting upon the wheel. The transverse control arm with the connected tension strut is arranged below a wheel drive shaft and--with respect to the driving direction--in front of a tie rod. In the top view, the tension strut extends diagonally toward the front, the transverse control arm and the tie rod having a positive position with respect to one another. They form a wheel steering pole situated outside the track width and behind the wheel center transverse plane.

Abstract: A wheel suspension for an axle of a motor vehicle, particularly a McPherson front axle, has a transverse control arm and a pivotally connected tension strut, the transverse control arm being held on the wheel carrier by way of a joint, and the body-side bearings of the transverse control arm and of the tension strut as well as of the connection bearing between the transverse control arm and the tension strut being constructed with a defined characteristic for the elastokinematic adjustment of the wheel under the effect of peripheral forces acting upon the wheel. The transverse control arm with the connected tension strut is arranged in an approximately horizontal plane and extends below the wheel spin axis approximately in a wheel center transverse plane. The tension strut is pivotally connected to the transverse control arm by way of a connection bearing and extends at an angle diagonally with respect to a longitudinal center axis of the vehicle.

Abstract: The device is composed of several separate elements consisting of at least one central tubular element connected, on one side, by means of a first ball-and-socket joint and a first compensator to a first connector supplying preheated air and on the opposite side, by means of a second ball-and-socket joint and a second compensator to a second connector. In order to reduce the length of the device, the second joint is oriented in the opposite direction to the said first joint, its center of curvature being located on the axis of the said second connector on the inside of the latter.
