Title: Oil cooled high power inductive coupler.
Inventor: WOODY GEORGE R
IPC: H01F38/14
Filed: 1997-07-23
Abstract: An oil cooled inductive coupler for use with an inductive charging system that charges propulsion batteries of an electric vehicle. The coupler is connected to a power source by way of a coaxial cable that has power conductors for coupling power to the coupler, and cooling channels for coupling high dielectric strength cooling fluid to and from the coupler. The coupler has a housing with a flood box formed therein having an open interior that forms a conductor termination area. The cooling channels are coupled to the flood box, and the power conductors are terminated in the termination area and are exposed to theb cooling fluid that is pumped therethrough to cool them. A heat exchanger having a fluid flow path therethrough is coupled to the flood box and permits the cooling fluid to circulate therethrough. A primary winding is secured or bonded to the heat exchanger, a magnetic puck is disposed in an opening in the heat exchanger, and upper and lower primary winding covers enclose the heat exchanger. The cooling fluid is pumped through the coaxial cable, the flood box and the heat exchanger to cool the primary winding, the magnetic puck, and the power conductors, to permit high power levels to be transferred between the power source and the propulsion batteries of the electric vehicle.

Title: Process for the production of polyacetal copolymer.
Inventor: YAMAMOTO KAORU
IPC: C08G2/18
Filed: 1997-04-10
Abstract: A polyacetal copolymer excellent in qualities such as heat stability is economically produced by a simple procedure through copolymerization wherein trioxane is used as the main monomer. In producing a polyacetal copolymer by copolymerization wherein trioxane is used as the main monomer, the copolymerization is conducted by the use of a non-volatile protonic acid as the polymerization catalyst to attain a rate of polymerization of 60 percent or above (based on the whole monomers), and then the residual monomer content of the polymerization system is lowered to 5 percent by weight or below based on the polymer by separating and removing unreacted monomers from the polymerization system by vaporization, the vaporized unreacted monomers being recovered.

Title: Displacement of magnetic domain walls at high speeds - using gallium-substd. yttrium iron garnet in pulsed magnetic field
IPC: G11C19/08
Filed: 1974-04-05
Abstract: On a substrate of gadolinium gallium garnet, a film of gallium-substd. yttrium iron garnet is formed, by epitaxial growth from the liq.phase, with a pref. direction of magnetisation perpendicular ot the plane of the film. This element is placed in a gradient magnetic field (max. 6 kOe/cm.) thus creating a domain wall, and an auxiliary static magnetic field Hy of a few hundred Oe applied perpendicular to the domain-wall. using a coil connected to a generator, a pulsed, driving magnetic field Hz is created (build-up time 8 ns, repetition frequency 100 kHz) of max. strength 16 Oe. By means of Hy and Hz, the domain-wall can be displaced from one stable position to another, and with the aid of a polariser, analyser and photomultiplier, a ray of light passing through the film will be detected by the alteration in intensity due to the Faraday effect. The detection signal can be calibrated in terms of the wall displacement using ans oscilloscope and direct observation with a polarising microscope. The high speeds produced are suitable for use in data processing applications.
