Abstract: ABSTRACT OF THE DISCLOSURE     A control system for a gasoline dispensing nozzle which includes a locking system for placing the nozzle in an inoperative mode once the nozzle automatically shuts off.  Resetting of the locking system is then required before operation of the nozzle can again be commenced.  The locking system includes a biased member which maintains the automatic shut-off system in its disabling mode once it disables the nozzle.  This locking system is designed primarily for use on a dispensing nozzle with a vapor receiving system and is used to discourage an operator of the nozzle from overfilling a gasoline tank, which results in increa-sing the risk of spilling  gasoline or forcing gasoline back through the vapor return line.  An alternative embodiment using magnetic locking means is also provided.

Title: High resolution electron energy device and method
Inventor: HUNZIKER HEINRICH E

Granted: 1980-12-09
Abstract: HIGH RESOLUTION ELECTRON ENERGY DEVICE AND METHOD        ABSTRACT OF THE DISCLOSURE  A device and method for obtaining high resolution of electron energy in an electron beam is described.  The device has a resonance chamber containing a gas which exhibits a narrow scattering resonance at a specific electron energy valve.  The device utilized the narrow resonance property of the gas to filter the electron energy spectrum at that energy value.  A preferred embodiment is a spectrometer having an electron accelerator, an electromagnetic filter, a resonance chamber containing helium, and a trapped electron detector device. The electrons in the beam are accelerated and the beam is passed through an electromagnetic filter centered at approximately 20.614 eV   The filtered beam passes into a resonance chamber where the electrons have inelastic collisions with the helium atoms to produce the He21S excited state.  The He21S scattering resonance has a narrow width of less than 0.001 eV at its energy threshold of 20.614 eV and serves as a filter.  Due to the steepness of the initial rise of the resonance structure the resolution of the spectrometer is about 0.0001 eV.  The trapped electron device then detects the flux density of the scattered electrons.

Title: Deposition mask and methods of making same
Inventor: HAMMER ROBERT
IPC: C23C14/04
Filed: 1977-07-13
Granted: 1981-01-27
Abstract: DEPOSITION MASK AND METHODS OF MAKING SAME         Abstract of the Disclosure The invention provides a reinforced mask which enables closely spaced strips or other narrowly separated parts of a deposited pattern to be formed upon a substrate by a non-line-of-sight deposition process (such as ion plating or sputter deposition) without causing unwanted voids or discontinuities to appear in the deposited pattern at points that underlie the reinforcing ribs on the mask.  The mask is formed by a selective material removing process that produces a this web adjoining one or more relatively thick ribs that provide rigidity to the web.  In those parts of the mask where the reinforcing ribs extend across slots or other openings in the web, the masking material is removed to a depth which exceeds the web thickness, thus raising the undersides of the ribs above the web surface to provide clearance for the vaporized material which is being deposited upon the substrate through the mask openings so that this material has ready access to points located directly beneath the ribs as well as points that are between the ribs. The ribs therefore can serve their reinforcing function without producing unwanted voids or thin spots in the deposited pattern.
