Abstract: A modular housing assembly comprises a base cabinet body having a height and four orthogonal wall elements. A fifth wall element is angled with respect to the first, second, third and fourth wall elements and a pedestal is fixed below the third wall element. First and second lateral protective walls overlay the first and second wall elements and extend along the height of the cabinet body.

The rain and dustproofing is improved by the invention in that an air inlet and outlet are fitted in the top of the cooler housing away from the control box, a cover component is connected to the top of the cooler housing at a distance therefrom, projects on all sides of the cooler housing and forms around it a downwardly open ventilation grille and is divided by partitions in the cover component into at least two chambers connected to the air inlet and outlet.

Abstract: A particle sensor operates in ambient air at an ambient air temperature and includes (a) a light source projecting a beam of light, (b) a light trap aligned with the beam of light and comprising at least one light-energy-absorbing surface at a surface temperature, (c) a nozzle flowing particle-entraining air through the beam of light, and (d) an opto-electrical system detecting light scattered by a particle. In the improvement, the sensor includes a cooling apparatus in heat transfer relationship to the surface and absorbing heat from such surface. The surface temperature is maintained at or below a value which substantially eliminates thermally-induced electro-optical disturbances in the sensor.

Abstract: An apparatus for warming water in an ice fishing hole. The apparatus includes a support, closed heat-transfer liquid conduit and heated liquid circulated throughout the conduit.
