摘要:
A kit for making permanently sealed transparent fingerprints using differential adhesion, including dry ink and means for applying the ink to fingers, a transfer strip having a backing sheet, a transparent adhesive print strip, and a protective cover, a transparent record sheet, print adhesive adhering together the protective cover and the adhesive print strip, backing adhesive adhering together backing sheet and the adhesive print strip, and the adhesives having such differential adhesion as to cause greater adhesion between the adhesive print strip and the backing sheet than between the adhesive print strip and the protective cover, and greater adhesion between the adhesive print strip and the record sheet than between the adhesive print strip and the backing sheet.

A method for manufacturing a carpet material that typically includes applying a coating to a substrate where the coating includes the reaction product of a B-side that includes an esterified vegetable oil-based polyol and a catalyst and an A-side that includes an isocyanate and the reaction product of a B-side that includes a vegetable oil-based polyol and a catalyst and an A-side that includes an isocyanate. The polyols may optionally be blown, oxylated, and/or neutralized.
摘要:
The present invention includes a bio-based carpet material that includes tufts, a backing, a pre-coat, and a backing material wherein the pre-coat includes the reaction product of a pre-coat A-side having a pre-coat isocyanate and a pre-coat B-side and the backing material includes the reaction product of a backing material A-side having a backing material B-side. The pre-coat B-side and the backing material B-side may include a polyol at least partially derived from petroleum, a vegetable oil, and/or a transesterified polyol and a cross-linker and a catalyst.
摘要:
A shampooing apparatus or device that is a portable, lightweight, and easily operated for providing automatic shampooing and/or conditioning. The apparatus comprises a body having a dispensing head and adapted to contain at least one but preferably two capsules one of which may contain a shampoo concentrate and the other a conditioner. The body receives these capsules and also receives liquid under pressure from a source of the liquid. In the two capsule version there are separate output ports that couple to a common entry port into a cylindrical cavity of the dispensing head. The dispensing head is of pulsating type including a rotor. In an alternate embodiment in place of the capsules are provided externally disposed containers for the conditioner and shampoo.
摘要:
Tufted or woven article having a unitary backing is prepared by applying to the underside of a tufted or woven textile article, a polyurethane-forming composition comprising(A) a relatively high molecular weight polyether polyol;(B) a relatively low molecular weight polyol;(C) an organic polyisocyanate or polyisothiocyanate;(D) an inorganic filler component.The present invention describes a carpet comprising (I) a primary backing; (II) a yarn tufted or woven through said primary backing thereby creating a yarn bundle on the underside of the resultant tufted or woven textile article and (III) a polyurethane composition applied to the underside thereby encapsulating the yarn bundles and adhering the yarn bundles to the primary backing; said polyurethane composition comprising the catalyzed reaction product of the composition described above.
摘要:
Method of installing a tip on a tube for making a probe cover comprising: axially, movably supporting the tube on an axially movable support pin with the pin extending beyond the end of the tube; placing a tip on the end of the pin that extends beyond the tube; applying a force to the tip to engage the tip with the end of the tube; applying a force to the end of the tube engaged with the tip to curl that end of the tube inwardly about the tip; and applying heat to the tip to soften that end of the tube engaged with the tip and cause it to reform about the tip in the inwardly curled form induced by the force applied to the end of the tube.
摘要:
In an electronic thermometer system for measuring and displaying temperature including a counter for counting pulses representative of the temperature measured; a first display device; a second display device; and a count modifying circuit responsive to a first predetermined count in the counter for indicating a first modified preestablished count for display by the first display device and responsive to a second predetermined count in the counter for indicating a second modified preestablished count for display by the first display device and a third modified preestablished count for display by the second display device.
摘要:
Polyurethane curable systems that contain an aminated glycerol as a catalyst to enhance the cure rate of the systems. The systems are based on polyoxyalkylene polyols that can be either polyether or polyester polyols. In addition, the polyols can be those that are provided by natural oils, such as soybean, corn oils, and the like. The polyols are typically dihydroxy functional, but can be tri- or quadra-functional or more. The systems are comprised of the reaction of such polyols with organic isocyanates, including the use of chain extenders from diols, or a mixture of triols and diols, such that the overall functionality of the mixture is generally less than 2.3. The organic isocyanates are also at least di-functional and can be tri- or greater functional, with regard to the isocyanate groups used on such molecules. The polyurethane systems can be, for example, elastomers, sealants, adhesives, or foamable systems.
