Patent DE-2355198-A1 (DE)
Title: Stoneware pipe joint assembly - using elastic rolling rings for spigot and socket components
Inventor: ARLT GERHARD
IPC: F16L21/025
Filed: 1973-11-05
Abstract: The main patent provides for integral projecting rings to project from the sides of elastic rolling rings to assist in fitting them to the spigots in an untwisted manner before pushing a spigot into a socket. Because of the wide tolerance limits in the radial space between spigot and socket, for any size of pipe, two different sizes of cross-section of the ring (or two different grades of elasticity in the material) are needed to cover the range. This addition provides for rings of non-circular cross section, narrower in the axial direction but deeper radially to ensure ease of fitting but adequate tightness when the ring rolls into place. Typical dimensions are given for a particular standard size of pipe.

Title: Printing cylinder for rotary photogravure machine - has greater elastic deformability at ends than at centre
Inventor: KOEBLER INGO DIPL ING
IPC: B41F13/18
Filed: 1973-11-17
Abstract: The cylinder covering is made of elastic material, e.g. rubber, and, because of a narrowing of the cylinder core diameter at the end regions, it has a larger wall thickness in this section than in the centre portion of the cylinder. The cylinder core is made of steel or steel casting and in a second design has a constant diameter over its total length as well as an intermediary layer whose elasticity lies between that of the core and cover and whose wall thickness diminishes towards the ends of the cylinder. The covering and e.g. hard rubber intermediary layer can be applied by winding them onto the core and subsequently vulcanising them in position.
Patent DE-2403129-A1 (DE)
Title: Open-end spinning unit sliver feed - has controlled clamping points to reduce sliver volume during yarn repair
Inventor: STAHLECKER FRITZ
IPC: D01H4/50
Filed: 1974-01-23
Abstract: The system to control the sliver feed to an open-end spinning unit, while a broken yarn end is being reversed into the spinning rotor to be spliced into the end of the newly-spun yarn, has adjustable clamping points working in conjunction with the fibre opening unit for the sliver. More spec. the clamping points which are set according to the required staple fibre length, are formed at one end by the feed roller and a sprung trough for the opening roller to work on the sliver, the other clamping point being located along the line of sliver travel where the sliver is pressed against a guide. One arm of the trough is in the form of a double lever between the clamping points which also acts as a guide for the pressure unit. A sensor controls the action of the opening roller and clamping point by switching it in and out of action according to the required sliver feed according to the operating condition of the spinning rotor. The system ensures that a reduced volume of drawn staple fibres is fed to the rotor, relative to the reduced speed of the spinning rotor during the splicing phase, to prevent a build-up of fibres through an overfeed of the sliver.
