Title: Condensate outlet valve for sterilising container - in which valve is operated by series of discs which snap from one position to another when certain temps. are reached
Inventor: WAGNER PETER
IPC: A61L2/26
Filed: 1991-04-05
Abstract: A sterilising container condensate outlet valve opens when a certain temp. is reached and remains open until the temp. falls below a certain level during the drying phase. The valve temp. sensor consists of an arrangement of discs (28) which snap from one position to another when certain temps. are reached. The discs bear on one side against the valve disc (26) and on the other side against a fixed stop (36), and are located in a sleeve (30) which holds the valve disc and can be moved axially. This sleeve is normally held in the valve open position, and is located externally by a ring (32) around the outlet (24) on the container floor (18) and internally by the fixed stop (36). The opening spring (42) is in the form of a coil spring surrounding the sleeve and bearing at one end on the ring (32) and at the other on a flange (40) on the sleeve. USE/ADVANTAGE - Used in containers for sterilising surgical instruments, etc. The valve remains tightly closed so that the vacuum in the container at the end of the sterilising process is not lost.

Patent DE-4134831-A1 (DE)
Inventor: ADLER UWE DIPL ING
IPC: B60L3/10
Filed: 1991-10-22
Abstract: In order to detect a critical driving torque or an information representing the coefficient of friction at the road adhesion threshold for a vehicle having several driven wheels (5), at least two of the driven wheels (5) are associated to torque controlling means (13) that allow the ratio between the driving torques of both driven wheels (5) to be varied. Torque detecting means generate a torque signal that corresponds to the strength of at least the highest driving torque among those of both driven wheels (5). Wheel slip detecting means (19) that detect the increase in wheel slip of the wheel (5) with the highest driving torque beyond a predetermined slip threshold are associated to the driven wheels (5). The information on the coefficient of friction is generated depending on the strength of the detected driving torque of the wheel (5) whose slip exceeds the slip threshold. In order to determine the information on the coefficient of friction, the distribution of the driving torques of front axle (7) and rear axle (9) is periodically and alternatively increased.
