  • Patent number: 4223227
    Abstract: In conjunction with a linear accelerator or a cobalt-60 teletherapy machine disposed in a room having a head mounted for rotation about a horizontal epicenter axis, and wherein the head is adapted to direct a high energy beam at right angles to and intersecting said axis at an isocenter, there is provided right-angularly related opposed pairs of side and vertical lasers whose beams are focused upon said isocenter. This is to assure that when an isolated area of a patient's body to be treated is located at said isocenter, with the side and vertical laser beams impinging upon said isolated area, that high energy beams will at all times pass into said isolated area, as the radiation head is rotated up to 360 degrees about said epicenter axis. The present laser alignment fixture includes a support base adjustably mounted upon a universally adjustable patient platform. A turntable on said support base has a visual alignment fixture mount with top, bottom and side walls and a longitudinal bore.

  • Patent number: 4204371
    Abstract: A tool sharpening fixture for a conventional grinding tool having for example a base mounted on a table, at least a pair of spaced pulleys on the base and a continuous flexible abrasive belt mounted on and around the pulleys, with one of the pulleys being power-driven. The tool-sharpening fixture includes an elongated tool support arm pivotally mounted at one end on the grinding tool having a calibrated protector plate secured to the arm at its pivotal mounting. The arm is releasably retained in a predetermined angular position relative to the grinding tool and a tool anchor plate extends transversely of the arm, slidably mounted thereon for longitudinal adjustment to receive tools of different lengths. An elongated upright platen of arcuate shape and transversely flat is mounted on the grinding tool, which supportably and guidably bears against the interior surface of the belt. The platen preferably being in the form of a French curve substantially and terminating in a straight portion.

  • Patent number: 4091574
    Abstract: A tool sharpening fixture for a conventional grinding tool having a base mounted on a table, at least a pair of spaced pulleys on the base, and a continuous flexible abrasive belt mounted on and around the pulleys, with one of the pulleys being power-driven. The tool-sharpening fixture has an upwardly extending leg for mounting the fixture upon a support, such as the grinding tool table. An elongated tool support arm is pivotally mounted at one end upon the leg. A calibrated protractor plate is secured to the arm at its pivotal mounting. A manual fastening device on the leg secures the arm and protractor in a predetermined angular position relative to the leg. A tool anchor plate extends transversely of the arm and is slidably mounted thereon for longitudinal adjustment to receive tools of different lengths. A friction device is provided upon said anchor plate for securing the anchor plate in adjusted position on the arm.

  • Patent number: 4041994
    Abstract: An activity metering apparatus for metering predetermined activities of radioactive gas from a supply ampul to dose vials. The apparatus includes a shielded ampul housing, a fine metering valve communicating with the ampul housing chamber, a shielded vial housing and a hypodermic needle communicating with the metering valve and received through an opening in the vial housing. A Geiger-Muller tube is adjustably supported opposite an opening in the vial housing, whereby the activity of the radioactive gas dispensed to a partially evacuated vial within the vial chamber may be read directly by a standard laboratory rate meter.

  • Patent number: RE28754
    Abstract: A condition responsive circuit for generating an output signal upon the opening of a switch. An FET draws nominal current when the switch is closed. When the switch is opened the FET conducts to generate an output. The output may include an audio alarm, an oscillator and a transmitter to generate an alarm at a distant location, or a visual indicator.
