The improvement in an electroluminescent lamp and the method of making same, including providing a polymer on the lamp structure and encapsulating the lamp with the polymer in a hard surface moisture impervious layer on each side of the device through the application of pressure and heat at selected conditions of pressure and temperature.

Laminated electroluminescent lamp structure and method of manufacturing

A portable two-part fastening device having a female section including a keyhole, a spring within the female section, and a ridge supported by the spring, an open channel in the female section contiguous with the narrow dimension of the keyhole, and means for mounting the female section to one part of the device. A male section comprises a button larger than the keyhole but having a width less than the open channel, with a flattened stud connecting said button to the other part of the two device. The button has an indentation on the outer face thereof of a geometrical configuration so as to mate with the ridge on the spring. The narrow dimension of the stud has a width less than the narrow dimension of the keyhole whereby the button and the stud may be positioned such that the button passes through the open slot and the stud passes through the narrow dimension of the keyhole with the spring exerting a biasing force against the face of the button hole so that the button and stud are maintained within the female portion.

Portable fastening device

A packer apparatus for the internal sealing of pipe leaks having a cylindrical structure and a single sleeve located on the exterior of the cylinder. The single sleeve has a pair of inflatable chambers connected together in spaced relationship to each other and air hoses connect through the cylinder to each of the inflatable chambers for inflating and deflating the chambers remotely with air pressure. Chemical lines are connected through the cylinder and through the sleeve between the inflatable chambers. The cylindrical structure is made of two or more segments and is collapsible for reducing the size of the packer. The single sleeve is made of rubber reinforced with tire chord and is held to the cylinder only by the connections with the chemical and air lines.
