Title: Cooling tower plume control
IPC: F28C1/14
Filed: 1974-06-20
Abstract: A cooling tower having a standard wet evaporative cooling tower combined with a dry heat exchanger system. The dry section includes a plurality of vertically spaced heat exchange tubes positioned directly above the packing area of the wet section. Water to be cooled flows through the tubes for preliminary cooling and then is directly distributed over the packing area of the wet section via nozzles associated with the lower ends of each tube. The heat exchange tubes are spaced a greater distance apart than ordinarily found in a typical heat exchanger to achieve maximum heat transfer and minimum pressure drop. The tubes are supported from their lower ends and fixed in place at their upper ends by a rubber grommet received through the water basin floor. A finned tubular insert is removably received through the upper end of each tube for control of the water flow. The air flow to both the wet and dry sections are controlled by mechanically adjustable louvers or dampers.

Title: Pipe-following irrigation machine
IPC: B05B17/00
Filed: 1975-02-27
Abstract: An irrigation machine having traction wheels which run along the top of a pipe having self-closing hydrants spaced apart in the length of the pipe. The machine is guided to follow the course of the pipe. When the machine reaches a hydrant, the machine stops and a vertically-movable riser pipe in the form of a probe and connected to a water gun or other water distribution device automatically descends to open the hydrant valve and thus admit water to the riser pipe and to the water gun. The machine is fitted with a device which shifts the machine longitudinally of the hydrant as the riser pipe is lowered towards the hydrant so that when the probe end of the riser pipe enters the hydrant, the probe end will be in precise vertical alignment with the hydrant. After a predetermined time the riser pipe is raised, the hydrant valve closes and the machine travels along the pipe to the next hydrant.

Title: Corrective heating of pneumatic tires
IPC: B29C67/00
Filed: 1975-10-10
Abstract: Adverse effects on pneumatic tire performance caused by an excessive variation in radial force are reduced by localized heat treatment of the cured pneumatic tire.

Filed: 1978-04-28
Abstract: A washer having a controlled-gap scrubber is connected to the gas outlet of a pressure blast furnace and an expansion turbine for the recovery of energy is connected downstream of the controlled-gap washer unit while a bypass is connected across the turbine. The system has operating regions A and B on a diagram in which the gas pressure is plotted along the ordinate and the volume rate of flow of gas from said blast furnace is plotted along the abscissa, the region A being defined between the turbine-insertion and the turbine-operating characteristic curves plotted on the diagram, the region B being defined between the turbine-operating characteristic curve and the corrected blast-furnace characteristic curve. The pressure in the blast furnace where the operating point is in region A while the gas traverses the turbine is controlled by varying the gap width of said control-gap washer unit in response to the pressure. The pressure in said blast furnace when the operating point is in the region B is controlled by varying the cross-section of the bypass valve, the gap of the washer being controlled in response to the differential pressure thereacross.

Abstract: In a semiconductor device a field effect transistor of either the lateral or vertical type has an island-shaped first region (1) which is bounded at the bottom by a first p-n junction (5) having a high breakdown voltage and laterally by a second p-n junction (6) having a low breakdown voltage. The first junction (5) is formed with an underlying second region (2) of opposite conductivity type to the first region (1) and can be reverse-biased by applying a voltage between the second region (2) and a contact region (4) which forms a non- rectifying contact with the region (1). The doping and thickness of the first region (1) are so small that, before breakdown at the second junction (6) occurs, the part of the region (1) situated between the second junction (6) and the contact region (4) is fully depleted by the depletion zone extending from the reverse-biased first junction (5). In Figure 2 this contact region (4) belongs to the drain electrode (D), but in other embodiments it belongs to the source electrode (S) or gate electrode (G). In Figure 2 the transistor has a junction gate (7) but in other embodiments it may have an insulated gate or a Schottky gate. Integrated complementary transistors each in accordance with the invention may be formed (Figure 3) using a double epitaxial layer structure for the first and second regions (1 and 2).
