Abstract: A carrier comprising a single cut blank of stiff sheet material, such as cardboard, plastic or corrugated paper-board including a substantially rectangular center section and a pair of side or lateral sections. The center section has parallel fold lines or scores impressed along and between the long sides thereof whereby the center section can be incrementally bent to a semicircle and the distal edges of the lateral sections can be brought together. There are handle holes closely spaced from the distal edges of the lateral sections. The center section has end portions, which extend beyond the lateral sections, around which a band or strap or other binder can be located. This includes both the cut blank and the novel carrier made from it.

The essential ingredient of the local coating may be a local anesthetic. The condom may include a color-coded bump indicating on which side of the sheath the coating is located.

Abstract: An electroluminescent device comprising a composite structure including first and second electrodes, first and second electroluminescent layers between said electrodes, and an electrically-insulating layer between and contacting both of the electroluminescent layers, said electrically-insulating layer having a substantially-uniform thickness in a range that permits substantial tunnelling of electrons therethrough when as little as 10 to 30 volts are applied across said electrodes.

Abstract: Method comprises producing a pattern of alternate light and dark areas along a particular path on the back surface of a viewing window, scanning the image of the pattern along the projected path with a photodetector in such manner as to produce an alternating image signal, and then deriving the value of MTF (modulation transfer function) from the image signal. The viewability of images transmitted through the viewing window can be then characterized by a combination of values of MTF and SR (specular reflection).

Abstract: Prior to preparing an acid phosphor slurry for use in preparing dry photosensitive phosphor layers, particulate yttrium, lanthanum and/or gadolinium oxysulfide or vanadate phosphor is mixed with essentially water-insoluble particulate zinc phosphate in an aqueous medium. Then, the particle mixture is removed and dried. The invention includes both the novel method and the product of the novel method.

Abstract: A method for fabricating a glass CRT panel that exhibits high compressive surface stress and low compaction comprising thermally processing the panel during the initial annealing stage for a prescribed period of time at about those temperatures that produce minimum compaction, which processing temperatures are substantially lower than the processing temperatures that produce minimum surface stresses in the panel, and then cooling the panel to room temperature.

Abstract: A cathode-ray tube comprising a glass viewing window having, on its external viewing surface, an antistatic, glare-reducing, image-transmitting coating. The coating has a rough surface and is composed essentially of a silicate material and a metallic compound in proportions to impart the desired antistatic characteristic without substantially degrading the image-transmitting capability of the coating. When the tube is operated, the coating is grounded either directly or through the metal implosion-prevention system on the tube.

C., consists essentially of a minor proportion of an inorganic silicate binder and a major proportion of a particulate mixture of cobaltic oxide and zinc oxide in the weight ratio range of 4/1 to 1/1.

Abstract: A method for producing a stencil of PVA (polyvinyl alcohol) including applying and heat-drying to a surface a coating of an aqueous composition of PVA and dichromate sensitizer, and then exposing and developing the dried coating. The aqueous composition includes a fluorescein-type dye or combination of dyes in such proportions as to substantially reduce heat-hardening of the dried coating. The method is particularly useful for preparing etch-resistant stencils used in preparing precision-etched products, such as apertured masks for use in cathode-ray tubes.

Abstract: A glare-reducing coating, as for the surface of the viewing window of a cathode-ray tube, is prepared by (a) warming a glass support above room temperature, (b) coating a surface of the warm support with an aqueous solution containing a lithium-stabilized silica sol and drying the deposited coating, (c) washing the dry coating with water and (d) baking the washed coating, preferrably at about 90.degree. C.

The display may be made by producing a layer which is tacky in substantially the pattern of the desired matrix, and then contacting crystalline zinc-iron sulfide particles with the tacky pattern, whereby particles adhere to the tacky pattern, thereby producing the desired matrix.

Abstract: An intaglio inking plate comprising a printing surface having an aperture therein, a plurality of separately-movable bars filling the aperture and means for positioning each bar separately either flush or depressed from the printing surface. The positioning means comprises (1) means for moving all of the bars to their flush positions, (2) means for blocking the further movement of selected ones of the bars, and (3) means for moving all bars that are not blocked to their depressed position.

Abstract: In the novel method, light passes upwardly from a light source, through an optical element and then is incident upon a photosensitive layer. A transparent optically-neutral sheet, which may be of glass or plastic, closely spaced above the optical element intercepts extraneous matter that would normally fall on the optical element. At least during the exposing step, the sheet is moved with respect to the optical element to wash out degrading effects of the intercepted material.

The electrically-conductive coating is electrically floating and, preferably, is a substantially-continuous circumferential band on the inner surface of the neck of the CRT.

Abstract: In a method for preparing a luminescent screen which includes optionally depositing a light-absorbing matrix upon a support, depositing a phosphor-and-binder layer on the support, and then coating the phosphor layer with a film of organic polymeric material, the steps for salvaging the support and matrix, if present, substantially undisturbed while substantially entirely removing the overlying material. In the method, the overlying material is contacted with an aqueous hydroxide-and-peroxide solution until the binder and film are at least partially solubilized. Then, the overlying material is substantially entirely flushed away by flushing, sloshing, or low-pressure spraying with an aqueous medium.
