Abstract:
A method and apparatus for measuring radiation are disclosed in which a scintillation body intercepts incident radiation to cause the body to emit a population of scintillation photons, the population of scintillation photons is spectrally decomposed into at least a first subpopulation of photons and a second subpopulation of photons (the first subpopulation originating from faster time decay processes than the second subpopulation) and at least one of the subpopulations is detected.
Abstract:
A cathode-ray tube device for generating a bright light spot is provided, in the path of radiation, a container with a coolant from the cathode-ray tube containing a solution of about 0.5-2.0% by weight of a surfactant selected from the group consisting of sorbitan esters of fatty acids of 12-18 carbons, polyoxyethylene derivatives thereof and ethers of polyoxyethylene in polyethylene glycol 200-300 all of said container in contact with said solution being formed of polymethyl methacrylate and all surfaces of which container are in contact with said solution are provided with a thin layer of silicon dioxide.
Abstract:
Halos occurring around bright light spots generated by cathode ray tube devices in which the light emitted by the tubes is filtered by filtering solutions are significantly reduced by the addition of cinnamic alcohol and/or cinnamaldehyde to the solution.
Abstract:
A communications jack includes a housing having a top surface, a bottom surface, first and second opposed side surfaces, and a plug aperture configured to receive a mating plug at a front of the housing. At least one of the first side surface, the second side surface, the top surface, and the bottom surface of the housing includes a first feature configured to engage a first mounting structure associated with a first mounting opening to mount the jack in the first mounting opening. One of the top and bottom surfaces of the housing includes a second feature configured to engage an adapter to mount the jack in a second mounting opening that is different than the first mounting opening.
Abstract:
A monolithic solid scintillation body with a monocrystalline or polycrystalline morphology having generally constant luminescence from about 25.degree. C. to at least about 200.degree. C. and average crystal domain grain diameters of at least about 5 millimeters and being composed of zinc sulfide doped with copper and a method of measuring radiation using the scintillation body and an apparatus for measuring radiation are disclosed.
Abstract:
A material for use in a laser heterostructure which is lattice matched material to ZnSe and has a high band gap. The material is Mg.sub.y Zn.sub.1-y S.sub.x Se.sub.1-x with the ratio of sulphur to magnesium of 0.26/0.19. Lasing devices constructed from layers of this material and ZnSe can be either electron beam pumped or electrically driven.
Abstract:
A method for producing an optical waveguide which comprises imersing a wafer of K.sub.1-x Rb.sub.x TiOMO.sub.4, wherein 0.ltoreq.x.ltoreq.1, and M is P or As, for 1-64 hours in molten potassium nitride at 400.degree.-500.degree. C., followed by washing and immersing in a molten salt of Rb, Cs, or Tl at 240.degree.-335.degree. C., thereby causing the Rb, Cs, or Tl to replace the K or Rb cations. The resultant product has reduced mechanical damage to the waveguide surface.
Abstract:
A CRT device for generating a bright green light spot is shown. The device employs a terbium activated phosphor. Troublesome radiations emitted by the phosphor particularly in the 586 nm region are significantly decreased without significant decrease of the desired 544 nm radiation by use of a concentrated solution of a soluble praseodymium salt.

A material for use in a laser heterostructure which is lattice matched material to ZnSe and has a high band gap. The material is Mg.sub.y Zn.sub.1-y S.sub.x Se.sub.1-x with the ratio of sulphur to magnesium of 0.28/0.19. Lasing devices constructed from layers of this material and ZnSe can be either electron beam pumped or electrically driven.
Abstract:
A method for selectively applying particles having cores of magnetically-permeable material and outer, fusible surfaces to a lenticular, light-transmissive screen, such as a projection television screen. The particles are selectively deposited in grooves between lenticules of the screen by magnetically attracting the particles to tips of a particle carrier sheet which positionally correspond with the grooves in the screen. The screen is then positioned underneath the carrier sheet, and the magnetic attractive force is reduced to effect release of the particles into the grooves of the screen. Microwave radiation is applied to the screen with the deposited particles, and the magnetically-permeable cores concentrate microwave energy dissipation in the particles and effect selective heating of the particles until their outer surfaces fuse to each other and to the screen.
