Abstract: In the manufacture of plastic articles, particularly thermoset plastic sheets having good optical properties, by a process which involves forming the article on a surface to which the article tends to adhere, numerous and important advantages are realized by using, as a release agent which facilitates removal of the article from the surface, a salt of an addition product of a lower alkylene oxide which can be prepared by the fixation of a lower alkylene oxide on an organic material having a group reactive therewith, such as, alcohols, acids and amides, and subjecting the resulting product to esterification and neutralization.

Abstract: A constructed piston 1 is comprised of an upper part 2 produced from forged steel, and a bottom part 3, said parts being joined with the expansion screws 4. The bottom part 3 consists of a forged part 6 produced from steel, with the bosses 7 and an approximately tubular shaft extension 5 consisting of an iron material, said extension being joined with the part 6 by welding. In the lower zone of the shaft extension 5, the latter has a collar 8 that can be worked for the purpose of adjusting a piston weight within the tolerance range.

Abstract: Disclosed is a clamping device for a piston to be mounted, said clamping device being actuated mainly in the direction of pressure/counter-pressure, whereby the whole initial pressure is increased, resulting in greater anti-loosening safety. To that end two screws are placed very close to each other on each side of the piston, one pair being on the pressure side of the piston and the other pair on the counter-pressure side. Both screw pairs have on each side a common pressure member.

Abstract: The piston for use in an internal combustion engine, more especially a diesel engine, is provided with a piston barrel consisting of light metal and a head plate which consists of a metal having a lesser thermal conductivity but a greater high-temperature strength, for example steel. The head plate is fastened to the piston barrel with the aid of retaining screws, which extend parallel to the piston axis and are preferably designed as expansion screws. The head plate is supported against the piston barrel only by a ring-shaped rib along a narrow ring rib through which the retaining screws pass. A radially outwardly widening gap is left free between the opposite faces of the ring-shaped rib formed on the head plate and the ring rib of the piston barrel at room temperature and when the retaining screws have not yet been tightened. The surface of the ring rib of the piston barrel is convexly curved in the radial direction.The proposed curvature of the surface of the ring rib of the piston barrel has the advantage that the adjoining ring rib surface of the head plate finds for each oblique position an areal seating on the ring surface of the ring rib of the piston barrel.Due to the proposed curvature of the lower gap surface, a smaller gap dimension can be chosen over the entire radial gap length than in the case of a gap consisting of plane surfaces.

Abstract translation: 用于内燃机，特别是柴油发动机的活塞设置有由轻金属和头板组成的活塞筒，该活塞筒由具有较小导热性但较高高温强度的金属组成，例如 钢。 头板借助于平行于活塞轴线延伸的固定螺钉紧固到活塞筒，并且优选地被设计为膨胀螺钉。 头板仅通过沿着固定螺钉穿过的窄环肋的环形肋支撑在活塞筒上。 在室温下形成的环形肋的相对面和活塞筒的环形肋之间以及当固定螺钉尚未拧紧时，径向向外扩大的间隙是自由的。 活塞筒的环形肋的表面在径向方向上凸起地弯曲。 所提出的活塞筒的环形肋表面曲率的优点在于，头板的邻接的环形肋表面针对每个倾斜位置找到位于活塞筒的环形肋的环表面上的面位置。 由于所提出的下间隙表面的曲率，可以在整个径向间隙长度上选择比在由平面表面构成的间隙的情况下更小的间隙尺寸。
