Abstract: A cap system for enclosing a metallic fastener assembly extending through a structure includes a first securement mechanism positioned about a periphery of a washer of the metallic fastener assembly wherein the first securement mechanism includes threads. The cap system further includes a cap member including a sidewall having an inner surface which defines a cavity dimensioned to receive the washer and defines a second securement mechanism complementary configured to engage the first securement mechanism positioned about the periphery of the washer. An end of the sidewall of the cap member defines an opening which provides the washer to have access into the cavity.

Abstract: A protective seal cap assembly for enclosing an end portion of a fastener extending through a structure, which includes a cap member. The cap member includes a sidewall which defines an opening and defines an interior space within the sidewall and aligned with the opening, wherein the sidewall defines a central axis. The cap member further includes at least one rib which extends away from an interior surface of the sidewall within the interior space and extends in a direction along the central axis of the cap member.

Abstract: A containment cap assembly for enclosing a metallic fastener extending through a structure includes an inner cap with a projection extending from an outer surface of the inner cap and an outer cap includes a first end which defines an opening and includes an inner surface which defines a first space within the outer cap in communication with the opening. A dimension of the opening and of the first space defined by the inner surface of the outer cap are each greater than a dimension defined by the outer surface of the inner cap such that with positioning the inner cap within the outer cap, a second space is defined between the outer cap and the inner cap. A slot of the outer cap extends first curvilinear direction such that the projection positioned within the slot moves along first curvilinear direction with moving the inner cap into the outer cap.

Abstract: A cap assembly for enclosing a metallic fastener which extends through a structure. The assembly includes a housing having an inner wall and an outer wall which extends about and is spaced apart from the inner wall defining a space positioned between the inner wall and outer wall. The assembly further includes a plunger member with a side wall portion secured to an end wall portion. The side wall portion of the plunger member has a thickness dimension smaller than a distance between the inner wall and the outer wall to position the sidewall portion of the plunger member within the space. With the side wall portion positioned within the space, the end wall portion is positioned in alignment with the inner wall and with an opening defined by and through the inner wall.

Abstract: A cap assembly for enclosing an end portion of a bolt fastener includes a first cap member which includes a bore and a surface positioned within the bore which defines first threads and the first cap member also includes an external surface which defines second threads. A second cap member includes a sidewall which defines a receptacle with an opening which provides access to an interior of the receptacle and the sidewall includes an interior surface which defines third threads compatibly configured to engage the second threads. The third threads are positioned along the interior surface of the receptacle extending along a length of the receptacle a first distance and the second threads are positioned along the external surface of the first cap member extending along a length of the external surface a second distance wherein the first distance is greater than the second distance.

Abstract: A cap system for enclosing a metallic bolt fastener extending through a structure which includes a first securement mechanism positioned about a periphery of a bolt head of the metallic bolt fastener. The cap system further includes a cap member which includes a sidewall having an inner surface which defines a cavity dimensioned to receive the bolt head and defines a second securement mechanism complementary configured to engage the first securement mechanism positioned about the periphery of the bolt head. The cap system further includes an end of the sidewall of the cap member which defines an opening which provides the bolt head access into the cavity.

Abstract: An adhesive for applying to a creping surface in the process for dry creping tissue paper is disclosed. The adhesive comprises cationic starch and optionally a polyvinyl alcohol and a water-soluble, thermosetting, cationic polyamide-epihalohydrin resin. The adhesive provides high adhesion and doctorability for dry creping.

Abstract: Multi-layered tissue paper webs comprising biodegradable chemical softener compositions and binder materials are disclosed. The multi-layered tissue webs are useful in the manufacture of soft, absorbent paper products such as facial tissues and/or toilet tissues. The multi-layered tissue paper products contain a biodegradable chemical softening composition, preferably comprising a mixture of an ester-functional quaternary ammonium compound and a polyhydroxy compound. The multi-layered tissue paper webs also contain an effective amount of binder materials to control linting and/or to offset the loss in tensile strength, if any, resulting from the use of the chemical softening compositions. Preferably, the majority of the biodegradable chemical softening compositions will be disposed on the outer layers of the multi-layered tissue paper products where they are most effective at enhancing softness.
