Title: Moisture measuring rig for timber and tex - tile material
Inventor: KRUEGER HELMUT
IPC: G01N27/12
Filed: 1970-04-15
Abstract: The resistance of a measured distance of a specimen forms with a diode a voltage divider. The diode is connected in series with a compensation voltage from a second voltage divider which includes a thermistor. This compensates the characteristic of the diode against any shift by temperature changes. The voltage from the first voltage divider is amplified and recorded.

Between the two ends of the loop there is a small brush which helps to deflect the loops.
Patent DE-2102145-A1 (DE)
Title: Casting surface - with overhead feed of metal oxide powder to coat rising metal
IPC: B22C23/02

Patent DE-2214172-A1 (DE)
Title: Yarn monitor - using grooved roller in pathway containing aperture for light beam
Inventor: GOTTSPENN HERBERT
IPC: D04B35/10
Filed: 1972-03-23
Abstract: Designed for use in a quilting, knitting or weaving machine, the yarn tension holds back a grooved roller in its angled or curved slit which provides a pathway. Should yarn breakage occur, the relaxation of yarn tension allows the rollers to move and block the aperture through which light passes to a photo-electric cell, thus triggering a stop control signal. The purpose is to provide a simple unit, which is easy to install, and which can be used with translucent yarns.
Patent DE-2223100-A1 (DE)
Title: Belt conveyor roller - of foamed plastics with uniform cellular structure throughout thickness
IPC: C08J9/02
Filed: 1972-05-12
Abstract: Method utilises a mould into which a number of constituents are introduced and reacted to produce a plastics, esp. polyurethane foam, the constituents being selected so as to produce an agent possessing boundary surface activity which, by the polyaddn reaction, forms urea bridges and gives off CO2 as the expanding gas. The constituents are pref. metered and mixed together then foamed before being introduced into the heated mould. The mould may be rotated during the final stages of foaming. With this arrangement, involving the use of CO2 as an expanding gas, a high difference in structure between the surface and internal material is avoided, thus giving longer life to the roller when the internal shaft surfaces wear away.

Title: Polyisocyanate or polyurethane coating compsns - contg ester wax of montanic acid, giving good pot life and improved polishing
Inventor: HAVENITH LOTHAR DR
IPC: C09D175/04
Filed: 1973-02-10
Abstract: One- and two-component polyurethane lacquers contain 1-19 wt. % based on solid lacquer binder, of an ester wax of montanic acid. The lacquers dry and harden rapidly but have a longer pot-life than lacquers contg. metal soaps, even if film-formers such as nitrocellulose are present. The polishing properties of the lacquers are better, and the time before polishing is possible is reduced. The ester wax waxes are inert even to rapid hardeners, e.g. isocyanuratepolyisocyanate.

Title: Weft insertion device - shuttle-carried rotary spool wound before each insertion has weft gripping projections on flange
Inventor: HRDINA KAREL
IPC: D03J5/06
