Abstract: ABSTRACT OF THE DISCLOSURE       A chimney comprises a central column through which the combustion gases or the like are forced, this column terminating at its upper end in u nozzle of smaller cross-section, and an outer wall which surrounds the column while leaving an annular intermediate space into which air is forced under a pressure slightly above the pressure of the combustion gases within the central column, this outer wall joining the periphery of the column in the zone of the upper nozzle. Apertures are provided in the wall of the column just below the nozzle to connect the annular space and the inside of the column. Air is thus introduced centripetally into the stream of combustion gases, a part of this air becoming progressively mixed with the said gases while another part forms a protective thermally insulating sleeve around the jet of these gases which issues from the nozzle, thus delaying the condensation of water   droplets and the formation of a white cloud, which therefore only appears at a substantial height above the top of the chimney.

Abstract: ABSTRACT OF THE DISCLOSURE An oxygen analyzer for measuring the oxygen concentration in a measured gas, having a probe type detecting section carrying at its end a solid electrolyte constituting a partition wall, so as to produce a signal corresponding to the difference in the oxygen concentration between the inner side and the outer side of the partition wall is described.  The outer side of the electrolyte is adapted to be exposed to the flow of the gas to be measured or into a furnace through a hole formed in the furnace wall and the inner side of the electrolyte is exposed to flow of reference air, thereby to continuously produce a signal representing the oxygen concen-tration in the gas being analyzed.  The flow of reference air is achieved without a pump by dividing the hollow probe into two sections using a longitudinal partition.  The two sections commnunicate with each other near the electrolyte and respectively communicate with atmosphere remote from the electrolyte.  because of temperature differences a natural convection current is established causing air to flow from atmosphere consecutively through the two sections and back to atmosphere.

Abstract: HYDROSTATIC LOAD SENSE STEERING SYSTEM    Abstract A system for controlling fluid  low from a source to a steering motor and one or more auxiliary motors comprises a priority valve and a steering controller.          The priority valve has a housing that includes an inlet port connected to the source, a priority flow outlet port, an auxiliary flow outlet port, and a pilot port.  A biasing spring urges the priority valve spool toward a priority position directing all flow from the inlet port to the priority port.  The priority valve includes a pilot flow conduit directing a pilot flow of fluid through an orifice to the pilot port.  Pressure upstream of the pilot flow orifice acts on the priority valve spool in opposition to the spring, and pressure downstream of the pilot flow orifice acts on the valve spool in addition to the spring.          The steering controller has a load sense cavity communicating with a load sense port, and a neutral vent orifice which, when the steering controller is in neutral, communicates said load sense cavity with a return port for allowing a pilot flow of fluid from the pilot port of the priority valve to flow through said steering controller to the reservoir.  Upon actuation from its neutral position, the steering controller substantially restricts flow through the neutral vent orifice to the reservoir before its main flow control orifice opens.  As a result, pressure at the downstream side of the pilot flow orifice of the priority valve substantially increases before the main flow control orifice opens and assists the spring to quickly urge the priority valve spool to its priority position.  When the main flow control orifice is open the load sense cavity of the controller is connected to the downstream side of the main flow control orifice so that pressures across the priority valve are varied with pressure variations across the main flow control orifice in accordance with operator demand and steering load.

Abstract: VARIABLE PULLEY TRANSMISSION          Abstract: The present invention deals with a variable pulley transmission assembly operable between a prime mover and a driven means.  The assembly includes input and output pulleys each with a movable sheave, where the pulleys are connected by a flexible belt, a fluid-actuated and fluid cooled starting clutch (16), a forward-reverse-neutral gear arrangement and a differential drive system connected to the driver means.  The system also includes a control system to control the fluid actuated clutch (16) and the movable sheaves (68,152). The clutch includes a deeply grooved pattern (345) to provide adequate cooling with low pressure oil before its return to sump.  This assembly provides a slippable clutch that acts analogously to a fuse under certain conditions to avoid excess loads to the belt means and also to provide lower operating pressure limits on the movable sheave maintaining belt tension. The clutch further provides a low end lugging limit slip to thereby avoid "torsionals" being transmitted past the clutch. The invention likewise provides a continuously variable pulley (CVT) transmission that has a ratio range of 5.4 to 1.
