...space between them filled by tightly packed sawdust. Only the south side of its roof is of glass. Heat & light are provided by ten 500-watt lamps which hang close over the plants in double rows and can be raised as the plants grow higher. A thermostat turns on the lights if the temperature drops below 62°, turns them off at 68°. Even a little sunshine keeps the insulated structure warm enough to keep the lights off. On the average, the plants receive about four hours of artificial illumination per day. Under this regime it was found that...
...effort to regulate heating more closely, the Department has developed its own automatic control which consists of a thermostat, a single seated pressure-regulating valve, and an outdoor mercold thermometer. When the heat is turned on in the morning, the thermometer turns off the excess flow of steam and allows only enough to enter the building to maintain a constant temperature. If the outside temperature rises, the mercold thermometer still further shuts the regulating valve. This has greatly cut down the running expenses
...Fords were not wholly new models, but the 1933 model with improvements. Chief changes: 1) a new dual intake manifold to the carburetor to increase mileage 2½ mi. to the gallon, increase speed from 82 to 87 m.p.h., increase power 12%, improve pickup; 2) automatic thermostat that prevents warm water from the motor circulating through the radiator until the engine has warmed up, thereby improving cold weather starting; 3) windows that move not only up and down, but also slightly sideways to provide a slit for draftless ventilation; 4) a more stylish radiator grill; 5) increases...
...walls-4 ft. thick-are of brick, 8 in. of cork, an air space and concrete. Within that well-insulated casing is an inner structure of ten rooms. The inner building has its own, separate foundations, is further insulated from the outer husk by 6 in. of dead air. Thermostat control and automatic air conditioners maintain the ten rooms of the icebox at any desired temperature and humidity. Year-round humidity will be kept at between 35% and 45%. Temperature will not vary more than one-tenth of one degree from 68° F. The constant conditions are essential...
There was a steel fire door on the film room fitted with a thermostat to close it if the temperature became too high. But sometime before, a blundering plumber had placed a water pipe in such a way that although it did not prevent the closing of the door by hand, it interfered with the aim of the automatic closing device. The door failed to close when the film began to burn and the gases (both poisonous and explosive) issuing forth, were driven through the building by a ventilating fan a few feet away...
