摘要:
A vacuum insulation panel comprises a barrier film and a core material and a vacuum detection indicator. The vacuum detection indicator is configured to facilitate the evaluation of the integrity of the vacuum within the vacuum insulation panel. The vacuum detection indicator may comprise a cavity in the core material which allows the barrier material to form a depression when a vacuum is drawn within the panel. Accordingly, as the vacuum is reduced or lost, the depression formed in the barrier material will be similarly reduced or lost. In addition, the vacuum detection indicator may comprise a viewing window configured above the barrier material to permit the evaluator to readily determine whether the vacuum has been reduced or lost. Further, the vacuum detection indicator may comprise a spring-like device configured within the cavity.

摘要:
A vacuum insulation panel according to the present invention addresses many of the shortcomings of the prior art. In accordance with the present invention, a vacuum insulation panel comprises a barrier film and a core material and a vacuum detection indicator. The vacuum detection indicator is configured to facilitate the evaluation of the integrity of the vacuum within the vacuum insulation panel. The vacuum detection indicator may comprise a cavity in the core material which allows the barrier material to form a depression when a vacuum is drawn within the panel. Accordingly, as the vacuum is reduced or lost, the depression formed in the barrier material will be similarly reduced or lost. In addition, the vacuum detection indicator may comprise a viewing window configured above the barrier material to permit the evaluator to readily determine whether the vacuum has been reduced or lost. Further, the vacuum detection indicator may comprise a spring-like device configured within the cavity. Accordingly, upon a reduction in the vacuum with the panel, the spring-like device suitably uncoils to urge the barrier material towards the outer surface of the panel, i.e., the barrier material returns to its original configuration before the vacuum was drawn in the panel. Moreover, the vacuum detection indicator may comprise electrical contacts suitably configured to indicate that the barrier material has been returned to its original configuration, or may comprise a fluid device configured to release colored-dyes which can provide a clearly visible indication of the loss of vacuum within the panel.

In a device for compensating a torque that depends on rotation angle and results from the rotational motion of a mass around a rotation axis, the rotational motion is converted into a linear displacement of a movably mounted displacement unit along a displacement axis in a defined manner depending on the rotation angle. The torque acting at any given time is compensated by an elastic compensating element that exerts a force opposite to the linear displacement of the displacement unit. Such a device is particularly suitable for compensation of torques that depend on rotation angle in medical stands.

A measuring device is provided for determining the position of a susceptor in a reactor housing. The measuring device includes a central element, which can be fastened on the susceptor at a predefined location, and a plurality of sensing arms, which protrude from the central element beyond an outer periphery of the susceptor. The sensing arms respectively include a sensing section that can be brought in touching contact with a contact zone. The contact zone is formed by an inner periphery of the reactor housing or a component arranged in the reactor housing. Using the measuring device, the position of a susceptor of a CVD reactor is determined relative to the reactor housing or a component arranged in the reactor housing.
