Title: Titanium ceramic composite bodies
Inventor: LESCHEN JOHN GUNDLACH
IPC: C04B37/02
Filed: 1963-07-17
Abstract: A crystalline ceramic body consists essentially of a fired mixture of 40-60 parts by weight of MgO and 60-40 parts of MgO-Al2O3 spinel. The body is SiO2-free and has a linear coefficient of thermal expansion of 9.0 x 10-6 to 11.0 x 10-6 per degree C.  The bond is vacuum-tight. In examples the spinel is formed by mixing 100 g. Al2O3 per 40 g. MgO, adding moisture, and firing as pellets.  The fired pellets are crushed and milled, and the fines mixed with an equal weight of MgO and with alcohol.  The slurry is dried and screened, and the powder is compacted and pressed at 40,000 p.s.i.  The resulting slugs are washed, and sliced into pellets, which are sintered in a boat of the same composition. The ceramic body may be joined by solder to a pure Ti body to form a composite body, e.g. a thermionic converter or vacuum tube.

Abstract: 1347599 Resin-encapsulated electrical coils MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 20 June 1972 [22 June 1971 (3)] 28889/ 72 Heading B2E A method of making a resin-encapsulated electrical coil comprises: immersing the coil in a mixture of a liquid curable resin, a curing agent and a gelling agent, said mixture being in the form of a sol.; withdrawing the coil from the mixture; and curing the resin adhering to the coil said mixture being caused to gel after immersion of the coil but before said curing. The mixture is such that, as the temperature increases from t 0 , the gelling agent dissolves at t 1  to cause the viscosity to rise and the mixture to gel. When the temperature reaches t 3  the mixture once again becomes a sol. which reverts to a gel when the temperature is lowered below t 2 . The gelling agent remains dissolved even on cooling below t 1 . The coil may be immersed in a mixture above temperature t 3  then withdrawn and cooled, the resin being subsequently cured. Alternatively the coil is immersed in the original sol. which is heated above t 1  to gel the mixture, then the coil is withdrawn, and the resin is cured. Another method is to immerse the coil in the original sol., to withdraw the coil, then heat the coil to gel the mixture adhering thereto or to withdraw the coil into an atmosphere at a temperature sufficient to gel the original sol. The resin can be left to cure or heated to cure without exceeding t 3 . In the examples the resin is epoxy resin and the curing agent is boron tri-fluoride monoethylamine. Several coils may be immersed simultaneously.
