Nieuniknione w pracy przesunie- *) Wlasciciel patentu oswiadczyl, ze twórca wynalazku jest inz, Henryk Strzalkowski cia równolegle oraz ewentualne skrecenia tafli wzgledem aparatu nie wplywaja na wskazania.Rzutowanie na ekran promienia 1* nie jest konieczne.Aparat wedlug wynalazku ma szczególne za¬ stosowania przy ciagnieniu tafli szklanej, gdyz pozwala na pomiar grubosci tafli czy szyby szklanej w czasie jej wyciagania i do natych¬ miastowej regulacji jej grubosci w czasie tej czynnosci. PLPublished on October 10, 1957 OF THE POLISH PEOPLE'S REPUBLIC PATENT DESCRIPTION No. 39739 KI. 42 b, 12/02 Biuro Projektów Przemyslu Building Materialów *) Przedsiebiorstwo Panstwowe Wy distinguished Warsaw, Poland Device for continuous thickness measurement of glass panes! The patent is valid from December 17, 1955. The subject of the invention is an apparatus for continuous optical control of the thickness of the drawn glass pane without touching its surface. The apparatus and its operation are schematically shown in the drawing. It consists of a homogeneous light source Z, a diaphragm P with scratches drawn on the main beam 1 and auxiliary rays 2 and 3, a lens S and a shield E (frosted glass). Depending on the thickness of the pane T, the internally reflected part 1 "of the main beam 1 shifts between the radii 2 'and 3', determining its permissible limit positions. The ratio of the distances 1 and 2 to 2 and 3 should be equal to the ratio of the minimum thickness to the tolerance field Inevitable shift in the work- *) The patent owner stated that the inventor is inz, Henryk Strzalkowski, parallel and any twists of the pane in relation to the camera do not affect the indications. Projection on the beam screen 1 * is not The apparatus according to the invention is of particular use for the drawing of a glass pane, as it allows the thickness of a pane or pane to be measured while it is being pulled, and for immediate adjustment of its thickness during this operation.
