Abstract: An apparatus is described that enables the user to pull a fireplace grate partially out of a fireplace for ease of loading with fuel, and then to push the fuel-loaded grate back into the fire-making position. The apparatus consists of a platform on whose top surface are receptacles which receive the feet of the grate. The platform engages and slides on rails attached to a base resting on the floor of a fireplace.

Abstract: A compact apparatus with long lifetime for producing high-energy neutrons is described which is suitable for application to neutron well-logging and to activation analysis. It embodies a tritiated target bombarded by a beam of energetic deuterium ions, the ions passing through a magnetic field which rotates about the axis of the beam, thereby dispersing the ion beam into a plurality of ion beams, each with a single value of charge-to-mass ratio. Each of the separated beams impinges on a separate, concentric, annulus-shaped area of the target.

Abstract: An apparatus and method for generating high-energy neutrons are disclosed. Neutron emissive target material is deposited on one or more surfaces on a rotatable, hollow, toroidal target support. Said surfaces are bombarded by beams of ions of generally rectangular cross section, so that when the bombarded surfaces are viewed end-wise, a compact, generally square source of neutrons is provided, such as is required for collimation. A combination of molecular and atomic ions emitted from at least one conventional accelerator are passed through a magnetic field for the purpose of separating the ions into one homogeneous group of atomic and one homogeneous group of molecular ions before said ions are allowed to impinge on the target surfaces. One accelerator directs ions to each target surface as the target rotates. Coolant is directed through a cavity within the toroidal support for the purpose of cooling the target support and target material.

Abstract: A method and apparatus for the controlled combustion of combustible materials is disclosed whereby the combustion is confined within a slot defined by a plurality of combustible logs in longitudinal contact and opening toward the objects to be heated.
