Patent EP-0058213-A1 (EP)
Inventor: MARIELLA RAYMOND PEEL JR
IPC: H01J49/16
Filed: 1981-02-16
Abstract: Isotope separation, particularly separation of isotopes of lithium, is achieved by exposing a beam of atoms to radiation that selectively excites atoms of a particular isotope without exciting atoms of other isotopes of that element. The excited atoms are ionized by solar radiation (19a) and the ions attracted to an ion collector plate (23) maintained at a negative potential. The atoms not ionized are condensed on a grounded atom collector plate (24). Optionally, the solar radiation not absorbed by the system may be used to generate electricity. Lithium isotopes are useful in nuclear reactors and nuclear weapons.

Abstract: The method comprises the application of power to a microwave generating device with the application of power to an infrared heater. The opertional periods of each type of radiation device are automatically varied over the cooking cycle. The parameters of these periods are empirically predetermined for each broad category of food and retained in a nonvolatile memory. In one embodiment, the periods are adjusted to compensate for varying quantities of food and desired donenesses by relating them to a total cooking time per unit mass empirically predeterminded for each food category and doneness. Alternatively, the periods are adjusted by entering the food mass into a microprocessor in the oven. The microprocessor calculates the cooking time by use of the food category, food mass and power input to the microwave generating device. In either embodiment, the recipe may also include varying the microwave power and providing cooling air. Compensation for variations in initial heater temperatures are provided to allow cooking of a second item of food immediately after cooking a first time.

Abstract: A planetary friction transmission mechanism includes elastic planetary rollers (9) disposed between the outer ring (13) and one of the drive and driven shafts (3; 7) acting as a sun roller and carried by the bearing retainer (10) which is connected to the other one of the drive and driven shafts. The planetary rollers and the bearing retainer revolve round the sun roller while the planetary rollers rotate on their own axes, thereby accelerating or decelerating the driven shaft relative to the drive shaft to rotate the rotary member held on the driven shafts. The drive and driven shafts are formed with axial passages (15,16) connected to an oil source (T) for introducing lubricating oil therethrough and forcibly feeding the oil therefrom toward the radially outward direction through its radial passages for effective lubrication. The application of this mechanism to a rotor type open end fine spinning machine enables its driven shaft holding a spinning rotor to rotate at a far higher speed with extremely reduced noises, as compared with the prior art.
