  • Charged particle deflection
    Patent number: 4614872
    Abstract: An electron beam or similar charged particles may be deflected by passing through an electrostatic field produced in a deflecting structure. The degree of deflection is controlled by rotating the deflecting structure and path relative to one another. The beam may be rotated relative to the structure by a magnetic beam deflector which compensates for a range of electron energies within the beam so that all electrons are deflected in the electrostatic field by an equal amount.

  • Ultrasonic apparatus
    Patent number: 4257272
    Abstract: There have been proposed ultrasonic scanners in which a transducer is laterally scanned relative to a body known arrangements with lead screws for example can give rise to much vibration and have a high power requirement. It is proposed to scan with a linear motor drive. The scanning part including the transducer is put in an oil bath and the oil flow is balanced to act as a counterweight. The scanning part should, therefore, have neutral buoyancy, with the centers of gravity and buoyancy substantially coincident.
