Patent DE-2402524-A1 (DE)
Title: Bellows type pipe for accommodating length changes - has rings in the curved section for ensuring curved bending
Inventor: KALTNER HERBERT DIPL ING
IPC: F16L51/02
Filed: 1974-01-19
Abstract: The bellows type pipe is used for compensating changes in the length in pipework. The bellows has a sinusoidal configuration in the axial plane. The convex peaks of the corrugations are joined to concave sections by straight sections. A corrugation peak is reinforced internally by a ring made from circular cross section bar and the convex sections are reinforced externally by similar rings. The curvature of the peaks and troughs is such that it only partly contacts the curvature of the round bar. When the bellows accommodate changes in length then the straight parts of the corrugation are bent over the curved bar in such a manner that a smooth bending curve is produced. This curving reduces fatigue stresses at the region where the curved section joins the straight section. The use of the round supporting bars hence increases the life of the bellows. The dimensions of the rings in the bellows can be such that a slight preload exists in between the rings and corrugations which promotes smooth bending over a curved ring.

Title: Modifying cement during grinding - by adding sulphonated naphthalene-formaldehyde condensation product
IPC: C04B24/22
Filed: 1974-10-29
Abstract: Modification of cement by grinding in the presence of sulphonated condensation products of aromatic hydrocarbons and formaldehyde is improved in that an aq. soln. of these sulphonated condensates (pref. alkali sulphonates of naphthalene-formaldehyde condensation product), opt. contg. other water-soluble or -dispersible cpds. is continuously sprayed onto the cement during the fine grinding in an amt. corresponding to 0.1-4 wt. % of the sulphonated condensation product w.r.t. the cement. This introduction method is simpler and less expensive than the conventional admixing to the mortar. The water is evaporated from the condensate soln. because the cement is still hot during the fine grinding; therefore, there is no adverse effect on the hydraulic properties of the cement. Grinding at an elevated temp. results in reaction between the condensate and the cement components. Additives, such as surfactants, antifoaming agents, water-repellents, etc. can also be conveniently introduced by this method. The modification of the cement results in increased strength of the product and excellent surface. The fluidity of the cement-contg. compsn. is improved whereby saving in energy labour, appt. etc. is achieved. High early strength is attained.
