Abstract: The invention relates to a heat-insulating material acceptable for use, such as a bed blanket. The heat-insulating material has a reinforcing layer, a base layer bonded to the reinforcing layer, and flock fibers secured to the exposed surface of the base layer through a discontinuous coating of cured adhesive. The base layer can have a thickness of less than 0.0625 inch. The flock fibers can have a diameter in the range from about 3 denier to about 4 denier. The invention also relates to a method of making the heat-insulating material by providing a laminate of a reinforcing layer and a base layer of a thickness less than 0.

Abstract: An insertion device for extracting polarized electromagnetic energy from a beam of particles is disclosed. The insertion device includes four linear arrays of magnets which are aligned with the particle beam. The magnetic field strength to which the particles are subjected is adjusted by altering the relative alignment of the arrays in a direction parallel to that of the particle beam. Both the energy and polarization of the extracted energy may be varied by moving the relevant arrays parallel to the beam direction. The present invention requires a substantially simpler and more economical superstructure than insertion devices in which the magnetic field strength is altered by changing the gap between arrays of magnets.
