Abstract: Abstract A composition is described which comprises amorphous phosphorus-nitrogen-oxygen material having excellent thermal stability and low reactivity to a wide variety of chemicals.  The material is manu-factured using a chemical vapor deposition process.  The reaction chamber is maintained at a temperature between about 400-900°C with a suitable substrate placed therein.  Reaction gases containing phosphorus-nitrogen-bearing compounds and a source of oxygen are pas-sed through the chamber to deposit the phosphorus-nitrogen-oxygen film onto the substrate.

Abstract: ABSTRACT            A survey system for determining the shape of a fixed path along which there may be no line of sight from end to end.  The system comprises a mobile optical detector adapted to travel along the path and a plurality of optical sources which can be arranged along the path. As it moves along, the detector receives optical signals from consecutive groups of the sources and processing circuitry in the system deduces the angular positions of the sources and hence the shape of the path. In a coal mine, the optical sources are positioned on mine roof supports and the detector on a mining machine which traverses to and fro along the coalface. The system then determines the shape of the coalface.  The frequency with which the detector and processing circuitry scan the sources is compatible with the mining machine.  The sources can be retro-reflectors, in which case a primary optical source is mounted adjacent to the detector.

Title: Process for the production of novel radiation curable  microcapsular coating compositions
Inventor: AUSTIN ROBERT A
IPC: B01J13/14

Granted: 1981-09-22
Abstract: Abstract of the Disclosure This invention relates to a process for producing a radiation curable coating composition containing microcapsules having a hydrophobic  liquid core comprising the following steps:  An emulsion containing droplets of a hydrophobic emulsion component dispersed in a hydrophilic emulsion component is prepared.  The hydrophobic emulsion component comprises a hydrophobic li-quid.  The hydrophobic emulsion component additionally contains a first wall-forming material capable of reacting by condensation   polymerization with a second wall-forming material to form a polymeric capsule wall.  The first wall-forming material is soluble in the hydrophobic emulsion component.  The poly-meric capsule wall is substantially insoluble in the hydrophilic and the hydro-phobic emulsion components.  The hydrophilic emulsion component comprises an emulsifier dispersed in a radiation curable hydrophilic liquid.  The radiation curable hydrophilic liquid comprises water and at least one radiation curable polar compound.  The emulsion additionally contains the second wall-forming material. The emulsion is subjected, with stirring, to temperature conditions for a period of time sufficient to react the first and second wall-forming materials to form a dispersion of microcapsules in the hydrophilic emulsion component. The microcapsules have capsule walls substantially impermeable to the hydrophilic and the hydrophobic emulsion components.  The radiation curable dispersion so produced can be coated on a paper substrate and set by subjecting the dispersion on the paper substrate to radiation for a period of time suffi-cient to polymerize the radiation curable hydrophilic liquid to a tack-free resinous film on the paper substrate. The radiation is a combination of ultraviolet and infra-red radiation. The invention further relates to a radiation curable coating composition containing microcapsules. The microcapsules have a hydrophobic liquid core and are dispersed in a radiation curable hydrophilic liquid. The radiation curable hydrophilic liquid comprises a polar radiation curable com-pound and water. The radiation curable coating composition additionally contains a photoinitiator.

Abstract: ABSTRACT                   MONO-ENERGETIC NEUTRON VOID METER            The ability to measure the ratio of vapour versus liquid in a nuclear steam generating system is highly desirable particularly since, during transient events such as rapid depressurization, the vapour may not be in thermal equilibrium with its liquid and its distribution in the liquid may be highly non-uniform. By using a relatively mono-energetic neutron source such as Californium 252, exposing the medium under investigation to the radiation and using a proton recoil detector as an energy dis-criminating counter one can estimate the ratio of vapour to liquid by measuring the reduction of flux loss due to scattering when the medium includes vapour as well as liquid.

Abstract: 47,769 AN EFFICIENT VALVE POSITION CONTROLLER FOR USE IN A STEAM TURBINE POWER PLANT     ABSTRACT OF THE DISCLOSURE         An efficient valve position controller adapted for use in a steam turbine power plant for efficiently positioning a plurality of steam admission valves to substantially effect a desired power generation level is disclosed.  The power plant includes a boiler for generating steam to the turbine at a boiler throttle pressure that is governed by a pressure set point; a valve control means which is governed by a reference signal corresponding to the desired power generation level to position the plurality of steam admission valves in a state according to a predetermined valve posi-tioning pattern based on the value of the reference signal; and an electrical generator driven by the steam turbine to generate electrical energy.  A plurality of values of the reference signal are predetermined as being related to efficient valve position states for regulating steam admission to the turbine.  The controller adjusts the pressure set point at a desired rate and in a direction as determined by the difference between a selected one of the predetermined values and a present value of the reference signal.  Accord-ingly, the reference signal is modulated as a function of the pressure set point adjustment until the reference signal is substantially equal to the selected value at which time the reference signal is governing the valves substantially at an efficient valve position state and further pressure set point adjustment is inhibited.  In addition, when the reference signal becomes equal to a predetermined threshold 47,769 value which is indicative of the steam admission valves being substantially wide open, the pressure set point is adjusted to a preset value.

Abstract: BAND BRAKE AND ACTUATOR THEREFOR     ABSTRACT OF THE DISCLOSURE A band brake assembly includes a band which carries a friction lining for engagement with a rotatable member.  A casing surrounds the band and a hydraulic actuator cooperates with a pair of links which are engaged with respective ends of the band.  When the hydraulic actuator is operated, the hydraulic actuator is moved toward the rotatable member such that the pair of links are pivoted oppositely about the moving hydrau-lic actuator.  The pivoting links are coupled to the band such that move-ment of the hydraulic actuator causes the band to contract the friction lining into engagement with the rotatable member.  The pair of links are optionally provided with rollers which roll on the casing and the hydraulic actuator when the latter is operated.  It is also possible to eliminate the casing so that the rollers roll on the band when the hydraulic actu-ator is operated.

Unequal pressures upon the barrier shift the barrier, redirecting the flow within the valve.
