摘要： A fluid flow system for a spring-cushioned shoe is disclosed. The sole of the shoe includes a vacuity, a spring disposed within the vacuity, and a fluid passageway in fluid communication with the vacuity. The fluid flow passageway allows fluid, such as air, to escape the vacuity when the volume of the vacuity is reduced during a foot strike.

摘要： A monitor for determining a buildup of slag on the flame side of water cooled walls of coal fired steam generators and other heat transfer surfaces. This monitor has a body to be positioned in an orientation similar to the water tubes of the steam generator (or other heat transfer surfaces) so that any deleterious buildup on the surfaces will also be effected upon the exterior of the monitor. Positioned within the body of the monitor is a temperature sensor, such is a thermocouple having at least a hot junction. Also positioned within the body and proximate the sensor (e.g., thermocouple) is a heater unit having a high temperature portion located proximate the hot junction. In this manner, when the heater is energized, the hot junction is raised to a preselected temperature. By monitoring the time constant of temperature change of the sensor with current to the heater being cycled, information as to the degree of buildup on the exterior of the body can be obtained. Accordingly, deposit removing equipment of conventional type can be operated when the buildup has reached a point where a change in the heat exchange qualities of the surface has become ineffective. Additional temperature sensors (e.g., thermocouples) can be used to provide temperature information from which instantaneous heat flux can be computed.

摘要： A solid state thermal neutron detector. The improved detector for particularly high temperature applications of thermal neutron flux determination, employs a differential thermocouple unit having the hot junction positioned within a cylindrical pellet or compact of uranium dioxide (UO.sub.2) partially enriched in uranium-235. The cold junction is positioned within a cylindrical pellet or compact of depleted uranium dioxide, this second pellet having the identical mass as the first. The uranium-containing pellets are spaced apart by a cylindrical pellet of a high temperature insulator, such as MgO or aluminum oxide (Al.sub.2 O.sub.3). Similar insulator pellets are positioned outwardly from the uranium-containing pellets to prevent heat loss. The entire assembly is enclosed in a cylindrical sheath of a material resistant to the environment of the detector, with this sheath being radially swaged upon the pellets to achieve intimate thermal contact between the pellets and the differential thermocouple. In one embodiment, a plurality of differential thermocouples are inserted in alternating pellets. In a preferred embodiment, a heater unit is included with a high temperature portion proximate the hot junction and a lower temperature portion proximate the cold junction. The thermocouple is connected to appropriate measuring circuits and monitor, and the heater is connected to a regulated and adjustable heater supply. Provision for axial movement of the detector unit and for determining absolute temperatures are discussed.

摘要： A directional detector of gamma rays comprises a strip of an electrical cuctor of high atomic number backed with a strip of a second electrical conductor of low atomic number. These elements are enclosed within an electrical conductor that establishes an electrical ground, maintains a vacuum enclosure and screens out low-energy gamma rays. The detector exhibits a directional sensitivity marked by an increased output in the favored direction by a factor of ten over the output in the unfavored direction.
