A phosphonate ester (vinyl phosphonic acid reacted with equimolar diol) will cure on command (e.g. exposure to light) in the presence of an initiator. By adding inert filler, poly(vinyl phosphonic acid), ion-leachable glass powder and water, a command-curable dental cement with glass ionomer characteristics is obtained.

The invention provides improvements to a composite member that has a plurality of plies. The improved composite member has (1) an interior ply which functions to dampen or resist sudden forces exerted on the composite member, (2) an intermediate load-carrying ply, and (3) an exterior abrasion-resistant ply. These plies have multiple, often intertwined fiber components disposed or imbedded with a m...

A line generator (31) for receiving fields of pixel data sampled from a video input signal and for generating additional lines of pixel data so that the display frames will have more lines than the fields. The line generator (31) has a motion detector (31a) that determines, on a pixel by pixel basis, whether some part of the current field is in motion. A motion signal from the motion detector (31a...

Dans la présente invention, il s'agit d'une nouvelle technique de photographie et de projection d'image ( photo, film et vidéo ) et d'une installation d'observation. A l'aide de cette installation l'être humain peut obtenir des images stéréoscopiques en regardant des images prises et projetées avec ladite technique

A filtration membrane module submerged with processed liquid in the processing tank. Plural plate-like, rigid membrane cartridges are vertically placed in parallel to each other as properly spaced from the adjoining membrane cartridges. The cleaning stream generating means for supplying a flow parallel to the membrane surfaces of the membrane cartridges opposes the gaps between the membrane cartri...

The present invention provides a glass sheet shaping arrangement whereby a glass sheet may be conveyed through a shaping station without being shaped and deposited into a glass collector beneath an upstream portion of the adjacent quench without impacting the lower quench or interfering with the operation of the quench. A furnace, shaping station and cooling station are all linearly aligned so tha...

The present invention provides a quench for cooling hot sheet material. The quench includes a plurality of generally horizontally extending, spaced apart nozzle assemblies, each having a longitudinally extending air supply conduit with orifices extending to an outer surface of the conduit. A first plenum is interconnected to a first end of each of the conduits and a second plenum is interconnected...

One aspect of the invention concerns a method of classifying particles according to their composition. In the method the particles (12, 68, 200) are irradiated with electromagnetic radiation, typically X-radiation, at respective first and second energy levels. First and second values are derived which are representative of the attenuation of the radiation by each particle. A third value is then de...

A control system/method for an at least partially automated mechanical transmission system (10), including a controller (106) operated engine brake (EB), is provided. The control system/method is effective to determine if selected upshifts into a target gear ratio are feasible (212, 214) or not feasible (216) under current vehicle operating conditions and to prohibit the initiation of not feasible...

A label is disclosed which includes a first, base layer coated with a pressure sensitive adhesive for attachment to a selected product. A layer of release material is coated onto a portion of the base layer. A second layer is coated on a portion of its underside with a pressure sensitive adhesive for permanent attachment to the base layer in regions thereof that are not coated with release materia...

Multiple-beam antenna with direct radiation and shaped beam, essentially comprised of an array 2, in which are arranged subarrays 3 shaping the high-power beam, and said array 2 being placed between radiators 1 and power amplifiers 4; furthermore consisting of another (conventional) array in which are arranged: adders 5, phase shifters 6 and connection lines 11. The most significant aspect of the ...

The subject of the invention is a system of video recording/playback by alternation of half-frames for the recording on video cassette of two different superimposed programs and for their separate playback, in which during the recording the two video signals V1, V2 of the two different programs are composed by a composer unit into a single resultant video signal V1+V2 consisting of one half-frame ...

A nozzle for an injection-molding machine has an elongated body centered on an axis and formed with an axially and longitudinally throughgoing passage, a threaded rear end, an outer wall, and a front end formed with a step having an axially forwardly directed annular face and a radially outwardly directed annular side surface set in from the outer wall. A removable nozzle element is set in the pas...

An electric toaster includes a housing defining a toaster cavity. A comestible support rack is mounted within the toasting cavity for supporting the bread to be toasted in a horizontal plane within the cavity. The toaster includes first and second heaters mounted respectively above and below the support rack. The cavity includes radiant energy reflecting surfaces above and below the support tray t...

A rear surface emission type light emitting diode emits light beams produced at a narrow emanating region out of the rear surface of the substrate.
