Abstract: A luminescent composition which is a uniform admixture of a least one phosphor having a particle size of about "one-half" micrometers or less and at least one sol gel compound in an amount sufficient to substantially encapsulate the phosphor. Luminous devices are formed by disposing this composition on a substantially transparent substrate. The use of particulate phosphors in an encapsulating medium protects the phosphor and provides dielectric strength or conduction as required. Improved luminous devices for displays and lighting are provided such as those finding use as flat panel displays and for backlights for liquid crystal flat panel displays.

Abstract: A luminescent composition which is a uniform admixture of a least one phosphor having a particle size of about ten micrometers or less and at least one sol gel compound in an amount sufficient to substantially encapsulate the phosphor. Luminous devices are formed by disposing this composition on a substantially transparent substrate. The use of particulate phosphors in an encapsulating medium protects the phosphor and provides dielectric strength or conduction as required.

Abstract: In the faceplate of a cathode ray tube or in an FED the amount of light emanating from the phosphor that reaches a viewer is increased by the use of internal and external antireflection layers and concavities between layers on the side of the viewer with respect to the phosphor layer.

Abstract: In the manufacture of a thin film electroluminescent display panel, patted transparent electrode stripes on a glass substrate are smoothed by:(A) depositing a uniform layer of dielectric material over the entire substrate bearing the patterned transparent electrode stripes,(B) applying a uniform layer of an organic flowable photoresist material over the layer of dielectric,(C) heating the coated substrate to a temperature at which the photoresist layer flows, and(D) etching back through the layers to the transparent electrode.

Abstract: A portable door lock and combined smoke and intrusion alarm has an upper forked end engageable with the door handle, a shaft extending in an adjustable length tube and terminating in a non-skid rubber end adapted to engage the floor or carpet. The upper end of the shaft is further retained in its mounted position by a retaining ring or cord. It has its lower end lying in a plane substantially aligned with the longitudinal axis of the shaft. A dual function alarm device is slidably mounted on the shaft and includes an actuator for it with a switch contact normally abutting or close to abutment with the surface of the door at a point below the door handle. Responsive to inward movement and pressure on the door the alarm will be actuated. At the same time, the locking action of the shaft and the upper forked end will divert the opening inward forces into forces directed against the floor so that the door cannot be opened.

Abstract: Batches of biscuits are fed to a wrapping machine by a continuously moving infeed conveyor including a series of pusher bars. The batches are fed simultaneously from a number of magazines, disposed alongside the conveyor and pitched closer together than the pusher bars, to a common carrier which then moves to a discharge position above the conveyor. The batches are dropped sequentially from the carrier onto the conveyor under the control of air valves.

Abstract: A combination door lock and alarm has an upper end clip engageable with the door handle, a shaft extending in an adjustable length tube and terminating in a non-skid rubber end adapted to engage the floor or carpet. The clip at the upper end of the shaft is angularly mounted and has its lower end lying in a plane substantially aligned with the longitudinal axis of the shaft. An alarm device is also mounted on the shaft and includes an actuator for it with a switch contact normally abutting or close to abutment with the surface of the door at a point below the door handle. Responsive to inward movement and pressure on the door the alarm will be actuated. At the same time, the locking action of the shaft and clip will divert the opening inward forces into forces directed against the floor so that the door cannot be opened.

Abstract: A heater usable for indoor and outdoor use including a body having an upper and a lower portion. The two portions are separated by a grate adapted to support a solid fuel within the upper portion. The lower portion is operable to receive a receptacle for a lighted semi-solid fuel. The heater can be used in two modes, in a high heat output mode in which the solid fuel is first lit by the semi-solid fuel that is then removed or in a lower heat output mode in which the upper solid fuel is dispensed with and the heat is given off by the lower portion semi-solid fuel receptacle only. The upper portion of the heater is selectively closed or opened by a lid to allow heating operation or to provide damping operation when the lid is in its lowered position.

Abstract: Apparatus for turning over a procession of articles of generally rectangular shape and having opposite longer and shorter sides, comprises a feed conveyor including pushers which engage successive articles in the procession to advance them in an upright condition along a dead plate, a support platform, disposed beyond the end of the dead plate, for supporting the undersurfaces of the articles as they leave the dead plate and continue to be advanced by the pushers, the support platform and the pushers having a relative movement effective to cause the articles to topple forwardly in succession from the support platform, and a support positioned to receive in a lying condition the articles toppling forwardly from the support platform at a level permitting further conveyance along it of the articles by the pushers.

Abstract: An electro-luminescent structure comprising a laminar composite made up of pairs of semi-insulator films fabricated from substances developing high energy electrons when subjected to an electrical voltage each in association with phosphor films luminescing under electron impact from the semi-insulators.

Abstract: Apparatus for feeding a number of wrapping machines with chocolate bars or the like, produced continuously and advancing end-on in a procession in more or less regular files and rows comprising a series of successive modules which feed the individual wrapping machines. The modules are preceded by a separator which channels the procession into separate lanes. The modules form part of a conveyor system which advances the articles continuously along a horizontal path. The modules operate in succession to lift the articles in the associated lane from the horizontal path and deliver them to an intermittently travelling cross conveyor leading to one of the wrapping machines. When any packaging machine is unable to accept articles, the articles lifted by its module are returned to the horizontal feed path and the cross conveyor of that module is stopped.

Abstract: A wall comprising concrete blocks each having a longitudinally extending, wedge-shaped groove in one side thereof, the groove communicating with a pair of bores that extend through the block. The block is molded in a hollow shell or frame open at its top and bottom, the frame removably mounting a support from which depends a pair of cores by means of which the block bores are formed. Associated with the frame is a compactor and ejector member having at its lower end a base adapted to be accommodated snugly within the frame and having on its lower surface elongate, wedge-shaped grooving means that forms the groove in the block. The grooving means is longitudinally slotted to accommodate the core support and the grooving means and the base also are bored to accommodate the cores.
