1. The Rigs Sarkandaugava As Factory j z controlled by the Minietx7 for to e
Balding Uaterials Industry of the Latvian SSR (Minister - Aush p) It
existed before the scar and produced window panes for the requirements of the
Latvian Republic. The Germans did not destroy the factory in 1944 when they
Wt Riga. Soon thereafter the factory resumed production of window panes
with modernized Fourcault machisme. In 1945, the fac vory was producing
100--115.,000 sq. motors of window panes per month, Dwi.ng 1947, the factory
received numaraus visit from delegations and specialists from vryri glass
factories of the USSR, as well as from scientific insi,itutions Taorlad on
the production of building materials, such as the Sciontific ResearchInsti-

? During the whole of 1947, the factory worked at this K -' ~~,~- high speed and considerablr,
exceeded the factory output program? At the end of 19.47., the factory had al-
~: read' fulfilled the program for 1948. The quality of glass remained very ? high
and suffered in no way from this high production rate. In February 1947; the
Cfar to:y was awarded the Challenge Banner (Perekhodyashehoo Znanya) by the Cour
oil of Ulnistera 'of the USSR, the highest reward in the All Union
Socialist Competition. The main reason for the high speeds attained by the
factory in drawing glass lies in the alumo-ma
grsasial composition of glass; in
addition, the factory has worked out certain technical. measures for cooing
the moving glass ribbon, and for cooling the glass sass coming out from the
Z o .- a) slot. The factory produces window glass of varying " z medium or double -- 3 rim. and 3.4 ra; and thick m,. thickness s thin -~ . ~S. ,

length of all is 160 cm, and the width alters by 2 on. In addition , there
are 40.other supplementary sizes, and green'iouse glass of two di.nensionso
