945,854. Seaming non-metallic sheet material. FR. HESSER MASCHINENFABRIK A.G. Sept. 4, 1962 [Dec. 11, 1961], No. 33802/62. Heading B5K. [Also in Division B8] Seams in fibrous packaging material, such as paper or cardboard, are formed by applying high frequency pressure impulses in the region to be seamed. Blanks or a web of the fibrous material may be passed between a sonotrode of an ultrasonic generator and a fixed anvil. The sonotrode is pressed under a predetermined pressure against the parts to be seamed whilst the generator transmits pressure impulses, preferably in the supersonic range, to the sonotrode. The pressure vibrations are preferably applied parallel to the plane of the layers of material to be seamed. Seaming may be continuous or intermittent. The method is applicable to seaming tea infusion bags made of coarse fibrous, permeable filter paper.

The present invention has an object of providing, for example, a composition for optical materials which contains a polythiol that can be predicted and assessed, in a stage prior to polymerization/curing, as being clouded or not clouded after polymerization/curing, and thus can be determined as being good or defective. According to the present invention, the above-described object is achieved by, for example, a composition for optical materials which comprises a polythiol that exhibits an initial turbidity of 0.5 ppm or less and a turbidity of 0.6 ppm or less after the storage at 50° C. for 7 days, and an episulfide. Namely, an optical material made from a composition for optical materials which contains a polythiol satisfying the above turbidity requirements can be prevented from clouding to exhibit excellent transparency.
