Patent WO-0202840-A1 (WO)
Inventor: KRICKAU OTTO
IPC: C23C8/02
Filed: 2001-06-29
Abstract: L'invention vise à mettre au point des ressorts cylindriques à noyau de bonne dureté, qui présentent un très faible taux d'usure, même lorsqu'ils sont soumis à des sollicitations soutenues, ainsi qu'un procédé simple permettant notamment de produire de tels ressorts cylindriques. A cet effet, il est prévu des ressorts cylindriques se composant d'un acier contenant un constituant d'alliage nitrurogène, dans lesquels une couche de diffusion à base de nitrure forme au moins en partie la surface des ressorts cylindriques, ainsi qu'un procédé permettant de produire de tels ressorts cylindriques. Selon ce procédé, la surface de ressorts cylindriques consistant en un acier contenant un constituant d'alliage nitrurogène est convertie au moins en partie par nitruration dans un gaz de traitement à base d'azote en une couche de diffusion. Le constituant azoté dans le gaz de traitement est déterminé de manière qu'il ne se forme pas de couche de jonction à la surface des ressorts cylindriques.

But they are located on the logging tool so that they are subject to the same ambient conditions as are the transmitter and receiver coils.
Patent DE-2108000-A1 (DE)
Title: Melt level indicator for casting moulds
IPC: B22D45/00
Filed: 1971-02-19
Abstract: Device for indication of the reaching of a preset level of fill of a foundry metal mould consists of a probe made from a heat resisting material attached to a lifting device, capable of displacing it vertically between set limits. There is also an indicator which signals contact between the probe and the melt. Once contact is established the probe is immediately withdrawn from the mould and positioned in the folowing mould on receipt of a signal indicating its positioning. The signal on reaching contact between melt and probe is effected by the closing of an electric circuit. The system is reliable and simple, and permits automation of the casting operation.
