Abstract: A mechanism for feeding animals with liquid feed that can be withdrawn from a supply unit, such as an automatic soaking unit, and can be supplied to a suction unit via a conduit. A feed pump is placed in the conduit, with the conveying capacity of the feed pump being regulatable as a function of vacuum in the conduit.

Abstract: A method and apparatus for rolling tubes into tube plates, especially heat exchangers, with a tube roller. Prior to the rolling process, the desired holding expansion value is set, and during the rolling process the holding expansion is measured. When the preset expansion value is reached, the expansion is discontinued. The magnitude of the holding expansion is determined by ultrasonically measuring the changing thickness of the wall of the tube during the expansion. The apparatus includes a tube roller that is operated by a drive mechanism. Also provided is a roll controller that can be set to the desired holding expansion value. An ultrasonic measuring head is provided in the tube roller, and is connected with the roll controller.

Abstract: A hydraulically damped elastic engine mounting having a ring-shaped rubber spring member which takes up static and dynamic loads and is equipped with a damping disk immersed in a damping fluid in order to provide hydraulic damping. The damping disk is movably mounted with axial play between spherical or conical buffer surfaces, and is provided in the vicinity of the buffer surfaces with passages through which the damping fluid can flow. The free path of the disk governs the damping applied, and at the same time prevents undesirable impact noise by the special design of the parts which move in relation to each other. Moreover, the damping disk may be constructed in such a way that interfering cavitation phenomena produced in the two surfaces are suppressed. This ensures that the damping device is fully effective in all vibration ranges and under all conditions occurring while the vehicle is being driven.

Abstract: In combination, a vehicle wheel which has a rigid, one-part rim, and a belted pneumatic tire having a single-ply or multiple-ply carcass and substantially inextensible and/or tension resistant core rings in the beads. The rim has rim flanges and, adjacent thereto, seating surfaces for the belted tire. To permit simple mounting of the tire, there is proposed that, in the position of the mounted tire, the distance from the center of a core cross-section to the bead edge facing the seating surface is greater than the distance to the axially inner bead edge, so that the core ring is eccentrically mounted in this region of the bead.

Abstract: A method of and device for scanning thermographic pictures according to which an oscillating or rotary movement of an optical element of an optical system of a scanning device serves for scanning in a first direction, e.g., in the horizontal direction, and according to which the scanning movement in a second direction is effected perpendicular to the first direction by changing the position of the axis about which the oscillating or rotary movement was effected for scanning in the first direction.
