Abstract: The indicator light, preferably a LED, is mounted in a insulating housing secured by a pair of legs with relatively broad feet which are soldered to conductive pads on the surface of a printed circuit board. Preferably, the printed circuit board uses "surface mount" technology. The leads of the LED are spot welded to the legs to make electrical connections between the LED and the circuit board. The structure elevates the LED above the board surface, and/or allows mounting the LED close to the edge of the circuit board, and/or allows the light from the LED to be directed parallel to the board surface. A particularly advantageous use of the structure is one in which printed circuit boards are arranged in an array with the boards parallel to one another and the LED mounting structures near the end of each board so as to provide maximum visibility of the LEDs from many angles so as to quickly indicate equipment functional status to an operator or trouble-shooter.

Abstract: A printed circuit board is provided wherein a composite metal layer is affixed to at least one surface of a flexible dielectric substrate, the composite metal layer comprising an inner aluminum layer and an outer copper layer. Owing to the relatively high elongation of the aluminum layer, when the printed circuit board is flexed the circuit thereon does not crack.

The material comprises a thick film insulation matrix of standard viscosity; a thick film organic vehicle; and a plurality of dry, hollow, glass microspheres. The insulation matrix, vehicle, and microspheres are thoroughly combined into a homogeneous material of standard viscosity.

Abstract: A plastic carrier tape for electronic components and the like having cross rails at a predetermined distance below taping rails thereby allowing for a more uniform adhesion of a tape cover to the plastic carrier tape. This more uniform adhesion will allow for a uniform pull force to remove a tape cover thereby enabling the plastic carrier tape to be more easily used in an automated production line.

Abstract: A display panel comprising a structural layer of rigid material having a plurality of holes extending therethrough, a plurality of laminate sections fastened to the structural layer in parallel relationship, a fastening material fastened to the structural layer in an area between the laminate sections, and an attachment cleat affixed to the side of the structural layer opposite the laminate section. The fastening material is a VELCRO-type material that covers a linear array of holes in the structural layer. The structural layer is a sheet of pegboard material. The laminate sections extend longitudinally across the surface of the structural layer. The attachment cleat is fixedly attached to the side of the structural layer opposite the laminate sections. The attachment cleat has an angle cut along its lower edge for engaging a complementary angle cut in a support structure.

Abstract: The invention primarily concerns a pressure-sensitive adhesive tape, the adhesive layer of which is filled with glass microbubbles and has a dark appearance by virtue of (1) the microbubbles are stained glass which preferably is dark, and (2) dispersed throughout the adhesive layer is a pigment or dye which preferably is dark. More broadly, the invention concerns any coherent article filled with stained-glass microbubbles. The glass of the microbubbles preferably has an ultraviolet window, permitting the article to be made by photopolymerizing a matrix filled with the microbubbles.

Abstract: A microchannel plate has a platelike photosensitive glass substrate and a plurality of microchannels formed separately from each other and extending across the thickness of the substrate. A secondary electron-emission surface is formed on an inner surface of each of the microchannels. Accelerating electrodes formed on two opposite sides of the photosensitive glass substrate, so as to be partially in electrical contact with the secondary-emission surface. The microchannels are formed by applying ultraviolet rays to the substrate through a mask and removing irradiated portions of the substrate by etching.

Abstract: A perforated covering structure is described for hygienic-sanitary products, such as sanitary towels for women, comprising an upper layer constituted by a non-woven textile of fibers of hydrophobic material, an intermediate layer or core constituted by a film of hydrophobic material, and a lower layer also constituted by a non-woven textile of fibers of hydrophobic material. The covering structure is applied in direct contact with that face of the absorbent core of the product which is intended to face the body of the user in use.

Abstract: A recording sheet comprising a sheet of paper and porous particles provided on the paper surface, said porous particles having an average pore size of from 10 to 5000 .ANG., a pore volume of from 0.05 to 3.0 cc/g and an average particle size of from 0.1 to 50 .mu.m.

Abstract: The invention is a process for making a transmission mask which can be used in structuring a semiconductor substrate in an additive or subtractive way by two galvanic depositions of layers of which one provides the mask structure and the other a grid structure covering the openings in the mask structure. The thickness of the structure is freely selectable self-adjusting (within the limits of the known engineering methods). The aim is the production of a transmission mask with a constant effective thickness above the mask surface.

Abstract: A procedure for preparing a palatable aerosol foam of unpleasant edible oil containing up to 80% oil is disclosed. This has been achieved by incorporating an inorganic complexing agent, water, a sweetening agent, a sensory masking agent and a propellant present in an amount sufficient by itself to function as the whipping agent and propellant into the oil to form a pleasant tasting suspension without an oily mouthfeel, unpalatable taste and unpleasant odor. Each teaspoon of aerosol foam will contain from about 2 to 4 grams of oil.

Abstract: A thermal transfer ink sheet comprising a substrate and hot-melt ink layers formed thereon, said hot-melt ink layers having a coefficient of dynamic friction of 0.5 or more based on a soda-lime glass plate can prevent a color shift in superposed printed images on an image receiving sheet.

Abstract: Apparatus and a process for manufacturing multiple color thin walled hollow shells for parts such as automobile door panels, controls and instrument panels from dry thermoplastic powders includes a powder box divider to form two or more compartments in a powder charge box and means for joining the chrage box divider end-to-end with a mold separation edge on an open-ended heated mold for separating the mold into two or more sections; each compartment of the charge box has a different color powder. The charge box and mold are joined and then are rotated so that the powder is distributed into each mold section by gravity flow with the powder from each section flowing to the divider which separates the colors so as to form two or more tones on a resulting shell of cured material.

Abstract: A ski edge whose vertical flange and horizontal flange of the ski edge portions extend around the ski tip, the horizontal flange having a cutout in the region of the ski tip. The ski edge is one piece whose side edge portions are divided into successive sections in which the vertical flange is divided by slits, the individual successive sections are connected to one another by the horizontal flange. In the region of the ski tip and/or of the ski end, the vertical flange extends continuously and is, hence, not divided by slits, thus forming a strong tip and/or end protection.

Abstract: The medium and liners of a water resistant containerboard are each essentially completely impregnated by a liquid water resistant agent which also uniformly coats the surfaces of the medium and liners with a layer sufficiently thick to cover the outer extremities of fibers protruding from such surfaces.The coating and impregnation is accomplished by feeding a flat untreated corrugated containerboard in the direction of its open flutes and in a continuous movement into and out of a hot melt bath of the water resistant agent at a controlled speed sufficient to force the liquid agent through the flutes of the containerboard, so as to assure exposure of all surface portions of the board to the hot melt for the same amount of time at the same temperature conditions.
