  • Patent number: 11420796
    Abstract: Front and back panels have side seams that fix the panel side edges of the front panel to the panel side edges of the back panel and each extend a full vertical length of the respective panel side edges. A label formed from a separate piece of film covers one of the face panels between the side edges thereof, is disconnected from the one face panel between the panel side seams, has label side edges generally at the respective side panel edges, and secures the label to the one face panel. Respective secondary side seams are provided between the side edges of the label and the side edges of the one panel, and respective tear lines are formed in the label closely adjacent and generally parallel to each of the label side edges. There is printing on the label only between the tear lines.

  • Patent number: 4806490
    Abstract: The invention relates to a procedure to establish the presence of allergen-containing housedust, as results when or after housedust mites occur, in which samples of dust present in buildings are thoroughly suspended in a aqueous-alcoholic alkali metal hydroxide solution and, with the resulting extract, a color reaction using an aromatic diazo compound is carried out, the color reaction being evaluated with respect to its occurrence as an indication of the pollution of the dust with housedust mite residues. According to a particular embodiment, a paper treated with the aromatic diazo compound (and where appropriate with starch) is used for carrying out the color reaction. A further aspect of the invention involves quantitatively determining the allergological activity resulting from housedust mites in housedust samples.
