Abstract: An encapsulated plug-in electrically conducting component is provided for mounting in an electrical connector. In one embodiment an elongate conducting element is transversely disposed across two spaced-apart generally parallel terminal posts and is secured at each of its ends to near the end of each post. In the preferred embodiment of the present invention, the component functions as a fuse wherein the elongate conducting element is a generally cylindrical fuse wire and wherein a solid unitary body of electrically insulating material encapsulates the fuse wire and the ends of each of the blades that are connected to the fuse wire. In another embodiment, a center portion of fuse wire is encapsulated with a thermoplastic to form a cylindrical body. The projecting end of the wire are bent over against the ends of the body. Cylindrical end caps compressively engage the body and are maintained in electrical contact with the fuse wire by solder material within the end caps.

Abstract: A method for producing synthetic liquid absorbent granules to serve the same purposes as granules made from naturally occurring sorptive minerals such as absorbent clays. Water is mixed with powdered gypsum plaster in mixing apparatus and a paste or slurry condition results, with the volume of water relative to the plaster being varied to vary the bulk density and the absorption capacity characteristics of the ultimate granular product from each mix. The mix is taken from the apparatus and is allowed to set and harden in a form to be readily handled for crushing and sizing into desired screen mesh size granules, or the mix can be directly formed into pellets or granules so as to be allowed to set and harden and be correspondingly sized as the commercial product. Additives can be included in the mixing to vary the density and the absorption characteristics of the final absorbent granules.
