Patent DE-1959563-A1 (DE)
Title: Liquid crystal coated panels sensitive to tem - peratures or electric fields
Inventor: DENNLER BERND DIPL-CHEM DR
IPC: G01R5/28
Filed: 1969-11-27
Abstract: The panels are prepared by applying a solution of liquid crystals (preferably esters of cholesterin for temp. detection; nematic substances, pref. p,p'-disubstituted benzylidene-anilines for electrical phenomena) to a carrier (any organic high-polymer, metal or paper) with a roughened surface (by sand blasting embossing or application of a filler together with a binder and/or a suitable high-polymer) to fill up about 1/3 to 1/2 the pack height and coating the panel after drying with a suitable protective layer, which is firmly fixed to the carrier/crystal layer by the roughness. The carrier is pref. 0.03-0.2mm thick, the crystal layer 0.01-0.05 mm and the protective coating 0.02-0.1mm. The crystal layer is protected against contamination and the panel can be reused. There is no tendency for the protective coating to slip. Panels are used to detect heat evolution or conduction (for this the coating or the carrier contains a dark pigment for easier detection of the change) or potentials or are used as image screen material.

Title: Coolant duct for plastics granulator
IPC: B29B9/06
Filed: 1970-02-12
Abstract: Coolant is introduced into a granulator for polymerised plastic from an annular duct with uniform exit nozzles at regular intervals around it. Coolant enters through a tangential pipe. The cross-section of the duct decreases from the inlet, so that the reduction is proportional to the loss of liquid from the nozzles, the ratio of the cross-sectional area to the wetted perimeter is the same at all sections, and the end section has a final value (is not zero) and is added to the inlet section. System improves uniformity of flow from all nozzles.

Title: Sley drive - through rocker arms with connecting rod mounted at arm mid-point to reduce sley vibration
IPC: D03D35/00
Filed: 1970-07-28

Patent DE-2326216-A1 (DE)
Title: Gas sterilization after evacuation - in chamber through wetting by spontaneous superheated steam production
Inventor: KRICK GERD DR ING
IPC: A61L2/20
Filed: 1973-05-23
Abstract: A gas (ethylene oxide) sterilisation process requires that the treatment chamber is first evacuated and that water vapour is introduced to wet the bacteria cell walls for easier penetration of the toxic gas in the final stage. A small amt. of water is allowed to enter a preheated thick-walled evaporator tray from which the vapour escapes as superheated steam. This prevents the formation of condensed water droplets on the cell walls which would delay the diffusion of the toxic gas. It results in a fast and uniform wetting even when the material has a small volume and a large surface area.
