Inventor: MIYASAKA TSUTOMU FUJI PHOTO FI
IPC: G03C1/14
Filed: 1987-12-01
Abstract: A silver halide photographic material having at least one silver halide emulsion layer having been spectral­ly sensitized with an adsorbable spectral sensitizing dye is disclosed, wherein a hydrophilic dispersion medium con­tains a substantially non-adsorbable luminescent dye which is easily removable by development processing and satisfies the following conditions 1) to 3):
     1) The luminescent dye has an equilibrium adsorption of not more than 5 × 10⁻⁷ mol per m² of silver bromide grain sur­face in a 5% by weight gelatin aqueous solution containing silver bromide grains whose outer surface is composed sub­stantially of a [111] face under conditions of 40°C in temperature, 6.5 ± 0.05 in pH, and 10⁻⁴ mol/1 in dye con­centration in the solution phase;   2) The luminescent dye has an emission quantum yield of not less than 0.1 at room temperature in dry gelatin at a con­centration of 10⁻⁴ mol/dm³; and   3) The luminescent dye has an emission band at least a part of which overlaps an optical absorption band of the adsorba­ble spectral sensitizing dye on silver halide grains. Use of the non-adsorbable luminescent dye markedly improves spectral sensitivity of the silver halide photographic mate­rial without causing desensitization.

Abstract: A stripping tool particularly for fibre optic cables is shown in Figure 1 and has flexible and resilient jaws carrying blades to contact the conductor, and when excess pressure is applied to close the blades on the conductor, the jaws can flex. This minimises the risk of conductor damage and further, allows particularly high loading per unit area to be achieved when the blades tilt so that only the heel of each blade contacts the conductor.

Abstract: A calorimetry system which is especially suitable for on-line, continuous measurement of the heating value of coal and which provides heating value data which may be used to control coal-fired furnaces in public utility power plants has a calorimeter with a combustor and a mixing unit wherein heat from the combustion gases is transferred to air. The system has apparatus for pulverizing the coal and a gravimetric feeder for providing pulverized coal at a measured mass feed rate to the combustor. The system also has deviced for preheating the combustor and initiating self-sustained combustion of the coal therein without the need for further supporting fuel gases. Instrumentation in the system measures the flow rates of the cooling air, primary and secondary combustion air as well as the mass flow rates of the coal into the combustor. A computer is provided with input/output devices which is responsive to the measuring instruments (thermocouples and pressure gauges) for controlling the feeding of the coal and fuel gases during initiation of combustion and for computing the heating value of the coal. The computer may have a memory with storage for specific heat values of the constituents of the products of combustion of various ranks of coal (bituminous, subbituminous, lignite, etc.) and the average mass fraction of each constituent in the coal by rank so that the heating value thereof can be determined with accuracy. The combustor and mixing unit is constructed in a manner to return to the combustion gas and to the combined combustion gas and cooling air most of the radiant and convective heat losses in the system thereby minimizing the effect of heat loss and the effect of ambient environmental (temperature and pressure) changes on the accuracy of the measurement.

Abstract: A method of cleaning well shafts is described in which a washing liquid, consisting of the ground water with suitable admixtures, is forced out of the well filter pipe into gravel layers adjoining the filter-pipe wall and is drawn back again. Here, deposits, which reduce the capacity and are to be removed, can be dissolved with and in the admixtures so that they are dissolved by the washing liquid and are absorbed in the latter in the dissolved state. During the cleaning operation, the ion concentration of various ions, dissolved from the deposits, in the washing liquid is measured and the further cleaning operation is controlled as a function of the result of these measurements. In addition, summation-parameter command variables of the various dissolved deposits and of the washing liquid can also be measured, the further cleaning operation also being controlled as a function of these measurements.
