Abstract: Two materials having different coefficients of thermal expansion are brazed together by use of an interlayer of expanded metal therebetween. The expanded metal makes point-type contact with the two materials and accommodates stresses resulting from the expansion difference.

Abstract: A W-Ni-Co penetrator has a composition of 90 to 98 weight percent tungsten, the balance being nickel and cobalt, the weight ration of nickel to cobalt being between 1:1 to 9:1.

Abstract: The powder weight of high powder weight SrB.sub.4 O.sub.7 :Eu phosphor is reduced by milling the phosphor, blending it with EuF.sub.3 and H.sub.3 BO.sub.3, firing the blend and then milling the blend in water containing Sr(OH).sub.2.8H.sub.2 O.

Abstract: A ceramic dielectric having a low dielectric constant and a low dielectric loss tangent from room temperature to at least about 1100.degree. C. comprises a silicon nitride based material containing an effective amount of magnesium oxide as a sintering aid and an effective amount of a low dielectric loss promoter comprising iron oxide and/or chromium oxide.

Abstract: Red cathode ray phosphors are coated with a vapor deposited layer of cadmium selenide in order to achieve controlled color shifts in the light output of the phosphors. Such coated phosphors are especially suited for color television and monitor applications.

Abstract: This invention concerns a method of making electrical contact buttons comprising the steps of presenting a strip of clad metal having a width narrower than the diameter of a finished contact electrical contact button and having a thickness greater than the thickness of the finished electrical contact button to a coining operation where the strip is successively pressed between a coining punch and a coining die to successively plastically deform uniformly spaced apart portions of the strip into the configuration of the electrical contact button. Tranverse ribs are then formed in the spaces between contact buttons in order to prevent forward flow of the metal during plastic deformation thereof. The electrical contacts are then punched out of the strip.

Abstract: A diesel fuel heater which is readily adapted for serving as a retrofit to existing diesel filter components, e.g., such as utilized in some existing automobile diesel engines. The heater includes a cylindrical plastic housing, and a flat annular conductive mounting plate located within the housing and containing thereon a plurality of positive temperature coefficient (PTC) thermistors designed for contacting diesel fuel passing through the housing and for heating same. A contact spring means is utilized to provide electrical current to each of the thermistors, said contact spring means electrically coupled to an electrical terminal which projects from the insulative housing and is designed for being connected to a suitable power source. An adapter is utilized to interconnect the housing of the diesel fuel filter component with a disposable filter typically utilized with such a housing to maintain both of these members in a spaced-apart relationship.

Abstract: In the manufacture of an alkaline earth halophosphate phosphor, a tray is filled from an automatic loader with a predetermined weight of powder comprising a blend of raw ingredients for forming said phosphor. The filled tray is then vibrated with a pattern inserted therein to settle the powder into a powder mass having a shape that promotes uniformity of reaction when the powder is fired at a temperature that causes the raw ingredients to react and form said phosphor.

Abstract: The luminous efficiency of Y.sub.3 Al.sub.5 O.sub.12 :Ce phosphor can be increased by milling the phosphor to reduce its particle size, blending barium fluoride into the milled phosphor, and then reduction annealing the blend of phosphor and barium fluoride.

Abstract: An X-ray phosphor consists essentially of (Y,Gd).sub.2 O.sub.2 S:Tb where the ratio of yttrium to gadolinium is between about 93/7 and 97/3.

Abstract: Sintered phosphor chunks are deagglomerated by feeding the chunks into a crushing machine to break them into pieces small enough to be vacuum-transported to a vacuum tank from which they drop into a controlled device which distributes the phosphor pieces into a uniform flow. The pieces are then uniformly fed into a roll crusher having an upper pair and a lower pair of rolls, which crush the phosphor into pieces small enough for use in preparing phosphor coating suspensions.

Abstract: Red cathode ray phosphors are coated with a vapor deposited layer of cadmium selenide in order to achieve controlled color shifts in the light output of the phosphors. Such coated phosphors are especially suited for color television and monitor applications.

Abstract: A pigmented phosphor is prepared by coating phosphor particles with a coating of finely powdered carbon and colloidal silica.

Abstract: A photoreceptor device comprises a conductive substrate and an electrophotographic layer thereon. The electrophotographic layer comprises copper-chlorine activated cadmium sulfide blended with a light-absorbing material.

Abstract: A fluorescent lamp has a phosphor coating on the interior surface of the lamp envelope. Dispersed throughout the coating is a melted and solidified amorphous borate-phosphate frit to improve the adhesion of the phosphor.
