Abstract:
A blade for a hockey stick which can readily absorb impact from the puck, and can allow the user to feel the puck on the blade in contrast to conventional carbon fiber blades. The blade can include a blade member integrally formed of composite material having discontinuous fibers bonded within thermosetting resin. The blade member can have a blade periphery surrounding a central blade region. The central blade region can have a plurality of openings arranged in a pattern to form series of elongate criss crossing ribs that extend between and connect different sides of the blade periphery to each other. The fibers in the blade periphery can be in a generally jumbled orientation, and the fibers in the central blade region can be positioned within the ribs in a manner wherein each rib contains a plurality of fibers that substantially extend in said each rib's elongate direction.
Abstract:
An electron beam emitter including a vacuum chamber having a width. An electron generator can be positioned within the vacuum chamber for generating electrons. An elongate nozzle can extend from the vacuum chamber along a longitudinal axis and have an exit window at a distal end of the nozzle. The nozzle can have a width that is less than the width of the vacuum chamber. The electron generator can be shaped and dimensioned, and positioned with the vacuum chamber to form and direct a narrow electron beam that enters and travels through the nozzle, and exits out the exit window.
Abstract:
A system for sterilizing air includes an air duct for flowing the air therethrough. A first electron beam generator is positioned relative to the duct for irradiating the air flowing therethrough with a first electron beam. The first electron beam for disabling microorganisms within the air.
Abstract:
An apparatus for irradiating surfaces includes an electron beam generator for generating a beam of electrons. The beam of electrons exits the electron beam generator through an exit window. A robotic device moves the beam of electrons over the surfaces to irradiate selected regions of the surfaces. The robotic device includes a propulsion system for propelling the robotic device.
Abstract:
A filament for generating electrons for an electron beam emitter where the filament has a cross section and a length. The cross section of the filament is varied along the length for producing a desired electron generation profile.
Abstract:
An electron accelerator for generating an electron beam includes a vacuum chamber having an outer perimeter and an electron beam exit window. The exit window has a central region and a first end region. An electron generator is positioned within the vacuum chamber for generating electrons. The electron generator and the vacuum chamber are shaped and positioned relative to each other to accelerate the electrons in an electron beam out through the exit window. The electrons pass through the central region of the exit window substantially perpendicular to the exit window and through the first end region of the exit window angled outwardly relative to the exit window. At least a portion of the outwardly angled electrons are directed beyond the perimeter of the electron accelerator.

Abstract:
A novel parallel-filament type electron gun for electron beam irradiation accelerators or generators and the like having a plurality of longitudinally extending parallel transversely spaced substantially co-planar similar filaments for generating electrons and disposed between a lower co-extensive extractor grid and an upper co-extensive electrostatic lens surface for shaping the electron beam profile, and with constructional features that enable variable width and extremely wide guns to be achieved and with improved beam uniformity.
Abstract:
A novel technique and apparatus for shielding electron beam and similar product irradiation zones with a separable shielding housing extending transversely of the longitudinal line of product flow and slidably openable in a transverse direction orthogonal to both the electron beam and the direction of product flow, both in passing the beam and along the line, resulting in substantial space saving, more facile accelerating to the irradiation and product feed zone and less costly and sizeable shielding apparatus.
