  • Patent number: 10251498
    Abstract: A fitted sheet is disclosed which will fit either of two mattresses of different sizes without undue wrinkling or bunching of fabric. This fitted sheet has an elastic segment at each corner. Each elastic segment is attached to the top panel, one of the side panels and either the front panel or the rear panel of the fitted sheet. The elastic segments are substantially similar in size and shape and are stretchable in two directions. Each elastic segment also has a seam extending from the straight upper edge portion toward the free lower edge that defines a corner in the elastic segment when the elastic segment is in a relaxed condition. The corner is between the upper edge and the lower edge of the elastic segment.

  • Publication number: 20180361703
    Abstract: In a woven fabric the warp threads are woven in a weaving pattern in a warp direction of two warp threads up and then one down, adjacent columns in the weaving pattern being offset such that there are no rows in which the weft thread is always up. The warp threads are between 80 s and 100 s and the weft threads are between 60 s and 120 s. There are between 144 to 220 warp threads per inch of fabric and from 60 to 400 weft threads per inch of fabric. This fabric is smooth and soft like satin and durable like percale.

  • Patent number: 9999307
    Abstract: A fitted sheet which will fit both a standard-size twin mattress and an XL-size twin mattress without undue wrinkling or bunching of fabric is disclosed. This fitted sheet has a top panel, a first side panel attached to the top panel, a second side panel attached to the top panel, a front panel attached to the top panel, the first side panel and the second side panel, and a rear panel attached to the top panel, the first side panel and the second side panel. An elastic strip is proved near each corner or near two corners at one end of the fitted sheet. The elastic strips are oriented lengthwise on the fitted sheet and allow the fitted sheet to stretch and contract only in a lengthwise direction.

  • Patent number: 5141716
    Abstract: The present invention utilizes low volatility amines or alkanol amines to control caustic corrosion which can take place when a boiler system, treated with a coordinated phosphate/pH program, is "out of control".N-substituted hydroxyalkyl piperazines are also capable of mitigating caustic corrosion in coordinated phosphate/pH programs. Combinations of the compounds of the present invention and phosphate have also been shown to be efficacious at mitigating caustic corrosion in coordinated phosphate/pH programs.

  • Patent number: 4693866
    Abstract: Methods for chemically scavenging oxygen from an aqueous medium are disclosed. Linear, water soluble polyethyleneamines, such as pentaethylenehexamine, are added, as the sole oxygen scavenger, to the desired aqueous medium. Suitable environments for use of these amines comprise boiler feedwater and boiler steam condensate systems.
