摘要： A system for treating the soil and turf having a prescribed subsoil profile that includes a duct network located in the subsoil region having openings that are in communication with the subsoil profile. A supply line is arranged to connect the duct network with a blower that provides low pressure, high volume air to the duct network so that the air is pushed upwardly through the subsoil profile to provide either heating or cooling to the soil and turf. A ground surface heat exchanger is positioned between the blower and the supply line for transferring energy between the earth and the air moving into the duct network. Other materials for treating the soil may be added to the air flow by a pressurized system. The blower flow is reversible whereby excess moisture can be removed from the green.

摘要： A radiant heating system for a greenhouse utilizing radiator tubing formed from substantially gas impermeable plastic material. The system includes a radiator tube disposed overhead and formed from light transmitting material so that sunlight projecting into the greenhouse will be substantially transmitted to the plants grown thereunder and a second radiator tube disposed proximate the greenhouse floor and formed of similar plastic material. The radiated tubes are interconnected at one of their ends and a burner communicates through a manifold connected to the other ends of the radiator tubes to transmit a heated effluent through the tubes. Valve means and exhaust means are associated with the manifold. The valve means operates to selectively direct the heated effluent from the burner to the overhead radiator tube for subsequent movement through the inner connection and the floor radiator and back to the manifold for discharge from the greenhouse through the exhaust means, or to direct the heated effluent from the burner to the floor radiator tube for subsequent movement through the inner connection and the overhead radiator and back to the manifold for discharge from the greenhouse through the exhaust means. This allows for a primary heating radiator and a secondary or residual radiator in the greenhouse.

摘要： 527,998. Windscreen wipers. TRICO PRODUCTS CORPORATION. April 25, 1939, No. 12428. Convention date, Aug. 16, 1938. [Class 138 (i)] In a windscreen wiper of the pivoted arm type in which the wiper blade is readily detachable from the arm, the connection between the two parts is by a stud and slot. As shown, an elongated stud 9 on the wiper blade 1 is received by a slot 10 in the arm 2 and is retained therein by a spring 22 which closes the entrance 11 to the slot. The wiper blade is urged towards the windscreen by the spring 22 and is returned to normal position by the camming action of a ridge 24 in the spring engaging a groove 25 in the wiper blade, limited pivotal movement of the blade being allowed by the shank of the stud 9 engaging curved sides 12 of the slot 10. To permit disengagement of the stud from the slot, the spring 22 is disengaged from a shoulder 19 on the arm 2. In a modification, the stud is of bent sheet metal.
