Abstract: Improvements in heating and cooling systems which are steam powered, the (winter) heating system utilizing a steam/liquid heat exchanger and the (summer) cooling system utilizing a steam powered absorption machine; methods of and apparatus for substantially improving a steam powered heating system conventionally having a boiler, a heat source for the boiler, a steam/liquid heat exchanger, a steam trap for the heat exchanger, a condensate tank with a vent line to atmosphere and work to be heated; methods of and apparatus for substantially improving a steam powered cooling system conventionally having a boiler, a heat source for said boiler an absorption machine having a generator section and an absorption section, a steam trap for the generator section of the absorption machine, a condensate tank with a vent line to atmosphere and work to be heated; methods of and apparatus for markedly increasing energy efficiency and efficient functional capacity in the heating and/or cooling systems in question.

Abstract: Energy saving apparatus for selectively controlling the heating and/or cooling equipment in rooms of hotels, motels or the like permits automatic, thermostatically regulated deactivation of such equipment when the room is unoccupied and the temperature in the room is within a preselected range, automatic reactivation of such equipment when such temperature falls below or rises above such range, and controlled reactivation of such equipment when the room ready for occupancy. The apparatus advantageously utilizes portions of a typically pre-existing, conventional telephone installation, and particularly the tip and ring lines between a central station and a telephone in each room, for carrying all electrical power and signals required for effecting such temperature control.

Abstract: A tube cutoff device which includes a rotatable cutter head for radially slidably supporting a cutter and a pair of support rollers in circumferentially spaced relationship. A stationary tubular guide extends through the cutter head for permitting a tube to be fed therethrough and positioned between the cutter and the support rollers. A cam is rotatably supported on the cutter head and cooperates with the cutter and rollers for displacing same radially inwardly into engagement with the tube which is to be cut. The cutter head and the cam are rotatably drivably connected to first and second power trains, respectively, which cause the cam and cutter head to normally rotate at the same rotational speed.
