Title: Colour spot determination by measuring reflected light - uses transparent optical collector cooperating with thinner lens in utilising its total reflection
Inventor: EICHELBERGER WOLFGANG DIPL PHY
IPC: G01N21/47
Filed: 1979-06-09
Abstract: The loss-free measuring is intended for detecting the colour spot of a surface or through-dyed specimen. The light radiation, reflected from the examined surface, is completely connected and supplied to a light-sensitive detector. For this purpose, an optically transparent light collector or conductor with high refractive index is used, preferably of massive construction, or filled with a liquid. The collector utilises a total reflection on an optically thinner medium, and collects and bundles all emitted or reflected light beams above the measured specimen surface. Thus the entire collected radiation passes through a relatively small outlet window of the collector etc. The primary light used for measuring, is introduced on a point on which the reflected light impinges with lowest intensity. From there it passes through the collector etc. and is measured on leaving the same.

Title: Securing pin-bar to stenter chain link - using inclined bolt under longitudinal tension from tension in fabric
Inventor: CRAMER HANS
IPC: D06C3/10
Filed: 1980-05-16
Abstract: Pin bars are fixed to the chain links of a stenter chain by a bolt passing through an open-ended slot in the pin-bar into a tapped hole in the holder affixed to the chain link, the bolt being inclined away from the centre of the stenter-frame such that the tension in a fabric carried on the pins is partially converted into a tensional force on the fixing bolt. The slot in the pin bar is counter-bored to a size which will house the head of the bolt below the surface of the bar, the bottom of the counter bore being perpendicular to the inclined axis of the bolt. The tensional force on the bolt replaces the shear force which would be acting on a vertical bolt, preventing damage to or distortion of the bolt, and facilitating rapid exchange of the pin-bar.
