Title: Woven carpeting yarn monitor unit - with optical sensor and phased impulses for error to indicate fault
Inventor: WALTER ARTHUR DIPL ING DR
IPC: D06H3/08
Filed: 1973-04-16
Abstract: Designed for the quality control of carpetings, and other materials where there are parallel coarse yarns, A focussed light is reflected from the reverse side of the fabric with an impulse generator to provide impulses to match yarn interval. If the reflected light impulse signals and the generated impulses fail to agree, then a signal change occurs which indicates that a yarn is missing in the woven carpeting. The purpose is to give an accurate detection of yarn faults, in a unit which can be located close to the weaving station.

Title: Silo filler opening cover - slews about axis outside inflatable sealing ring perpendicular to opening flange face
Inventor: GRAMLICH FRITZ DIPL ING
IPC: F16J13/18
Filed: 1974-02-26
Abstract: The flange of the cover bears via an electric sealing ring against the flange of the opening, and the cover is designed to resist internal pressure, slewing on the silo by means of a bearing at one side of the opening. The slewing of the cover is outside the sealing ring and at right angles to the plane of the opening flange, and the cover is prevented from sliding axially on this axis. On the opposite side of the opening the cover is prevented, when in the closed position, from lifting off it by a stop fixed to the silo. The sealing ring is inflated by gas or fluit under pressure, so as to bridge the gap between silo and cover necessary to allow the latter to swing open.
