20140044239 | MINIATURIZED HIGH-SPEED MODULATED X-RAY SOURCE - A miniaturized high-speed modulated X-ray source (MXS) device and a method for rapidly and arbitrarily varying with time the output X-ray photon intensities and energies. The MXS device includes an ultraviolet emitter that emits ultraviolet light, a photocathode operably coupled to the ultraviolet light-emitting diode that emits electrons, an electron multiplier operably coupled to the photocathode that multiplies incident electrons, and an anode operably coupled to the electron multiplier that is configured to produce X-rays. The method for modulating MXS includes modulating an intensity of an ultraviolet emitter to emit ultraviolet light, generating electrons in response to the ultraviolet light, multiplying the electrons to become more electrons, and producing X-rays by an anode that includes a target material configured to produce X-rays in response to impact of the more electrons. | 02-13-2014 |

20140250617 | TWISTED WIRE BRUSH AND METHOD OF MAKING - A twisted wire brush comprises a wire core and at least one length of spring coil. The wire core has a first length, defines a core axis, and comprises at least two core wires intertwined. The core wires twist helically about the core axis. Each length of spring coil extends about at least one of the core wires, and each length of spring coil is pressed between the twisted core wires. In another embodiment, a method of making a twisted wire brush comprises providing at least two core wires, positioning a length of spring coil about each core wire, aligning each length of spring coil, and twisting each core wire about a core axis. In yet another embodiment, a grill brush comprises a handle, a plurality of twisted core wires attached to the handle, and at least one length of spring coil, each length extending about at least one core wire. | 09-11-2014 |
