Abstract: An electro-fusion fitting includes a body, and a magnetic alloy member which is continuous in the axial direction is embedded in the vicinity of a joint surface of the body. A shield member is arranged on the outer surface of the body in a portion where a cold zone is to be formed. The joint surface of the body and a joint surface of a member to be joined are brought into contact with each other. When a high frequency current is applied to the magnetic alloy member from a high frequency power supply by electromagnetic induction in this state, the magnetic alloy member generates heat, so that the body and the member to be joined are fused, and joined to each other. Since the shield member shields the electromagnetic induction, the magnetic alloy member in a portion where the shield member is provided does not generate heat, so that the cold zone is formed in the portion.

Title: Aminoalkylphosphonic acid containing ligands attached to solid supports for removal of metal ions
Inventor: BRUENING RONALD L
IPC: B01J39/12
Filed: 1992-09-14
Granted: 2002-12-03
Abstract: A method for the removal and concentration of desired ions such as Sb3+, Zr4+, Zn2+, Pu4+, Hf4+, Cu2+, Ni2+, Fe3+, Cd2+, Ag+, and Hg2+ from a multiple ion source solution which may contain larger concentrations of other undesired ions including H+ comprises bringing the source solution into contact with a compound comprising an aminoalkylphosphonic acid containing ligand covenlently bonded through an organic spacer silicon grouping to a solid inorganic support. The am-inoalkylphosphonic acid containing ligand portion(s) of the compound has an affinity for the desired ions to form a com-plex thereby removing the desired ions from the source solution. The desired ions are removed from the compound by con-tacting the compound with a much smaller volume of a receiving solution having a greater affinity for the desired ions than does the aminoalkylphosphonic acid containing ligand portion of the compound.  The process is useful in removing desired or unwanted ions of Sb(III) from acidic waste streams, streams containing concentrated Cu(II), Ni(II), Zn(II), and Ag(I), and also the removal of Zr(IV), Pu(IV) and Hf(IV) from nitric acid solutions containing large amounts of other ions as well removal of unwanted ions from other industrial or environmental streams.

Patent CA-2121294-C (CA)
Inventor: HERGET GERHARD H
IPC: G01L5/00
Filed: 1994-04-14
Granted: 1997-01-14
Abstract: The invention relates to the field of measuring instruments and, in particular to sensing apparatus capable of measuring displacement or deformation for the ultimate purpose of monitoring strain and/or stress. The vibrating wire measuring principle provides a very reliable method of measuring small deformations with high precision. Measurement apparatus utilizing this principle, however, tend to be limited in range to the elastic limit of the stretched wire. To increase the useful range of measurement of a vibrating wire monitor, a spring may be placed in series with the wire. In order to prevent the spring from vibrating during the resonancing  of the wire and thereby delaying the determination of the wire's resonant frequency, the invention contemplates isolation of the spring from the wire in a vibrational sense. In one form of the invention, isolation is achieved by causing a nodal point to be formed on the spring side of the wire. The nodal point may be formed by pressing a fret against the wire.
