Patent EP-0374807-A2 (EP)
Inventor: LISCOMB CRISTINA
IPC: B01J19/12
Filed: 1989-12-18
Abstract: A process and apparatus are disclosed for producing polymerized beads containing actives such as perfumes and pesticides, by forming droplets from a solution of monomers and the actives. The solution is subjected to ultraviolet light to initiate polymerization. The droplets are caused to fall through a reaction vessel as polymerization continues so as to polymerize substantially spherical beads containing the actives. In one embodiment, the droplets are irradiated as they fall through the reaction vessel. In a second embodiment, the solution is irradiated prior to droplet formation and the fall. The beads are collected and can be cured if necessary. The process is preferably performed in an inert gas environment which most preferably is nitrogen. A nitrogen stream can serve as a carrier for the monomers and active ingredients. The nitrogen environment is maintained in the reaction vessel and in the curing structure, if present.

Abstract: A fibre optic sensor, particularly for ascertaining fluid levels, utilizes at least two optical fibres or waveguides (1,2) having at least a portion thereof embedded in a transparent substrate material (4) of similar refractive index. One of the fibres (1) is coupled to a light source (5), the other (2) to a light detector (6). The source fibre (1) illuminates the interior of the substrate (4) so that light exiting the source fibre (1) is coupled to the detector fibre (2) when total internal reflection at the substrate-fluid interface occurs in the presence of a first fluid. In the presence of a second fluid of higher refractive index than the first fluid, there will be no coupling, due to the loss of light into the fluid by refraction. One mechanism for coupling light into the detector fibre (2) is fluorescence within that fibre causing it to provide a light signal which varies with the level of the second fluid. Several different embodiments, to achieve discrete or continuous level sensing or the sensing of other parameters, are disclosed.

The self-hold state can be released only by the radio telephone set (2) while the complete state hold can be released by any one of the radio telephone set (2) and the subsidiary telephone set (28). In the complete hold state, the radio circuit between the main station (1) and the radio telephone set (2) is disconnected.

Abstract: This invention relates to abrasive products having a resinous binder which bonds abrasive granules to a backing sheet or to a fibrous sheet. 
     In the manufacture of coated abrasives, a make coat and abrasive granules are first applied to a backing, the make coat is partially cured, then a size coat is applied, and the resulting construction is fully cured. Generally, the binders for the make coat and size coat are thermally curable resins. 
     In order to obtain proper coating viscosities with thermally curable resins, solvent is added to these resins. With polyester or cellulose backings, however, curing temperatures are limited to about 130°C. At this temperature, cure times are long. The long cure time along with the requirement of solvent removal necessitate the use of festoon curing areas. Festoon curing areas require large amounts of space and enormous amounts of energy. 
     The present invention provides an abrasive product comprising abrasive grains bonded to at least one major surface of a backing sheet by a binder formed from a blend comprising radiation curable monomer and a thermally curable resinous material. The radiation curable monomer can be selected from the group consisting of isocyanurate derivatives having at least one terminal or pendant acrylate group, isocyanate derivatives having at least one terminal or pendant acrylate group, and multifunctional acrylate monomers. The thermally curable resinous material is preferably a member selected from the group consisting of phenolic resins, urea-formaldehyde resins, melamine-­formaldehyde resins, and epoxy resins. The binder can be used to form the make coat, size coat, both make and size coats, or as a backing treatment for a coated abrasive product. The abrasive products of this invention can be prepared without the use of festoon curing areas.

Abstract: A magnetic head of metal-in-gap type having a magnetic core composed of a ferrite (4) and a magnetic alloy material (5), the magnetic alloy material being arranged in the vicinity of the head gap (3). A process for producing this magnetic head has the step of conducting a heat treatment at a temperature not lower than 800°C but not higher than 1200°C. The wear resistance of the magnetic alloy is improved so that no substantial difference in the wear amount is caused between the ferrite and the magnetic alloy material even after a long use of the head in sliding contact with a tape. In consequence, undesirable reduction in the heat output level is eliminated so as to ensure a stable head output.

Abstract: A dental floss holder is in the form of a box (20) with a drawer (22) in it. The bottom of the drawer includes a hub (38) which is spring biased to push a bobbin (24) mounted thereon toward an opposite side of the box. The bias is such that the bobbin drags with a predetermined force on an opposite side of the box to maintain tension in the floss. A result is that the bobbin does not unwind while in the holder, thereby precluding a snarled floss line. Also, the tension gives a smooth "pull" which adds a "feel" of quality to the floss. The "feel" does not change as the diameter of the bobbin changes with either an exhaustion of floss or changes in the diameter of a full bobbin. The hub is mounted on a dome having sides with a shape which guides and directs any floss falling off the bobbin back onto it.

Abstract: Character level text editing is performed on an image without recognizing characters, by operating on a character-size array obtained from a two-dimensional array defining an image region. A processor, in response to a request for a text editing operation, accesses an edit data structure that includes the image region array and performs the operation. The character-size array is obtained by dividing the image region array when necessary. An image region array that includes more than one line is divided along interline spaces. An image region array that includes one line is divided along intercharacter spaces. Character-size arrays are divided out of larger arrays by finding connected component bounding boxes, and then determining from the bounding boxes whether the connected components are likely to form a character. If so, the connected components are used to obtain the character-size array and spatial data about position, size, and shape of the character. Smaller arrays and spatial data can replace a larger array in the edit data structure. Smaller arrays are obtained only as necessary to perform a requested text editing operation, and if the edit data structure is not otherwise modified, obtaining a smaller array does not necessitate redrawing of the display. In addition to character level editing, a text editing operation can be performed on a sequence of arrays, such as a word, line, or a sequence that begins on one line and ends on another. The spatial data can be used to position arrays after insertion or deletion, to advance a cursor through the text, and to justify a line of arrays. A character-size array can be assigned to a keyboard key, and the key may then be used to insert that array into the text or to request a search for other arrays matching that array.
