Patent number: 4107661Abstract: A device is provided for a meter having an indicator, e.g. a pointer, and which detects the presence or absence of the meter pointer at one or more set points or between two set points. The device does not alter the operation of the meter and may be coupled to an alarm or other signal, or it may be used to actuate a mechanism under control of the meter. The device comprises at least one light-emitting diode which produces radiation which falls on a specific area of the meter face and on the meter pointer (if it is within that area) and is reflected from the meter face (and the pointer) to a phototransistor or other suitable receiver which "reads" the signal produced by the radiation reflected from the meter face and the pointer, if present in the area read. The device is mounted so that it can be moved to any desired area of the meter face. Preferably the device is mounted externally to the meter. However, it may be enclosed within the usual meter housing, without altering the operation of the meter.Type: GrantFiled: August 17, 1976Date of Patent: August 15, 1978Assignee: Horizons Incorporated a division of Horizons Research IncorporatedInventor: Robert J. Crosby

Patent number: 4092164Abstract: A method and apparatus for monitoring the buildup of fog in a non-silver free radical film while a latent image in said film is being optically developed, wherein the buildup of fog is sensed by radiation directed at a non-image area of said film and reflected from said area to a sensing device. The reflected radiation is altered as the buildup of fog takes place.Type: GrantFiled: May 27, 1975Date of Patent: May 30, 1978Assignee: Horizons Incorporated a division of Horizons Research IncorporatedInventor: Robert J.

Patent number: 4066459Abstract: This invention relates to free-radical, non-silver, photosensitive films, particularly those suitable for optical development as described in U.S. Pat. No. 3,510,300. The invention comprises the incorporation of compounds which contain an imine (--C.dbd.N--) function and a hydroxyl group into otherwise known photosensitive compositions to improve optical development and to retard dark fogging so as to thereby provide aging stability to such compositions. Preferably, an additional improvement comprises provision of an overcoat for the photosensitive composition of this invention when in the form of thin films on a support such as a polyester or a paper sheet or glass plate. The overcoat acts to improve the shelf life and photosensitometric properties of the photosensitive composition.Type: GrantFiled: January 26, 1976Date of Patent: January 3, 1978Assignee: Horizons Incorporated, a division of Horizons Research IncorporatedInventors: Paul L.

Patent number: 4033773Abstract: A colored image in a polymer binder is obtained by polymerization of a mixture comprising (1) at least one polymerizable monomer, (2) a halogen containing activator (free radical source), (3) a binder, and (4) at least one normally bleachable dye, dissolved in such mixture; the polymerization being accomplished by imagewise exposure of said composition to a suitable dose of radiation, and is accompanied by fixing of the dye to the photopolymer. As a consequence, the dyes lose their bleaching characteristic and when the exposed areas are developed with a strong acid such as one which would normally bleach the dye, the dye is bleached from only the unexposed areas. If the developer also includes an aliphatic alcohol, the unexposed areas may be removed, leaving a relief image with color in the raised portions.Type: GrantFiled: February 9, 1976Date of Patent: July 5, 1977Assignee: Horizons Incorporated, a division of Horizons Research IncorporatedInventors: James Marvin Lewis, Raymond Willis Newyear

The resist composition is deposited on a suitable support and is exposed to a pattern of radiation in the usual way. A negative image is obtained by development with an alkaline liquid.Type: GrantFiled: August 15, 1975Date of Patent: May 3, 1977Assignee: Horizons Incorporated, a division of Horizons Research IncorporatedInventors: Raymond W.

Patent number: 4014981Abstract: Combustion products, especially those from electric power generating installations burning high sulfur fuels are treated to remove solids and then to separate physically sulfur containing constituents, such as SO.sub.2 and/or SO.sub.3 from other gases in the combustion products mixture by means of an ultra high speed gas centrifuge or a gas cyclone. The recovered oxides of sulfur in a heated condition are utilized in any desired chemical reaction. For example, they may be passed over dry NaCl and reacted therewith to yield sodium sulfate and chlorine, both of which can be recovered, and/or they may be passed directly over suitable catalysts in the presence of air to produce a pure grade of sulfur trioxide which can be absorbed in water to manufacture concentrated sulfuric acid.Type: GrantFiled: May 21, 1973Date of Patent: March 29, 1977Assignee: Horizons Incorporated, a division of Horizons Research IncorporatedInventor: Eugene Wainer
