Abstract: ABSTRACT OF THE DISCLOSURE          A belt-driven transmission designed particularly for self-propelled, walking lawn mowers is provided.  The transmission is mounted on a deck of a mower between a front pair or a rear pair of wheels and is driven through a pulley on the engine drive shaft and a pulley on the transmission connected by a belt.  With this arrangement, the engine requires no special power take-off shaft to drive the mower.  Consequently, the transmission can be universally applied to many different self-propelled lawn mowers. The new transmission can also be equipped with a deadman's clutch. Further, it can be provided with a manually-adjustable pulley of variable diameter to provide different speeds and torque for the drive shaft of the driven wheels.  Also, in accordance with the invention, the drive shaft has a ratchet coupling device near each driven wheel to provide a differential effect for the wheels when the mower is being turned.

Abstract: Abstract of the Disclosure A method of producing viscous materials from sub-terranean formation comprises a plurality of steps.  At least two wells are drilled and completed into the subterranean forma-tion that contains the viscous material.  At least one of the wells is completed as an injection well and one of the wells is completed as a production well.  A plurality of electrode wells are drilled into the subterranean formation with the plurality of electrode wells being generally arranged in a pattern to define at least one path between the production well and the injection well with the length of the path being substantially greater than the distance between the production well and the injection well.  The electrode wells are spaced apart along the path at distances that are substantially less than the distance between the production well and the injection well.  Thereafter, a voltage is applied across the adjacent pairs of electrode wells to thereby cause an electrical current to pass through the subterranean formation between each adjacent pair of the electrode wells.  As the electrical current passes through the subterranean formation, the viscous material is heated to thereby lower the viscosity of such material. Following the heating of the subterranean formation in the vicinity of the path formed by the electrode wells, a driving fluid is injected through the injection wells to thereby migrate along the path and force the material having a reduced viscosity toward the production well.  The material is produced through the produc-tion well and by continuing to inject a heated fluid through the injection wells, substantially all of the viscous material in the subterranean formation and be heated to lower its vis-cosity and be produced from the production well.

Title: Control system for regulating large  capacity rotating machinery

Abstract: ABSTRACT           The control system of the invention regulates a centrifugal compressor having inlet guide vanes adjustable as one means for varying the compressor capacity.  A variable speed motor is connected to drive the compressor, and provides another means for regulating the compressor capacity.  The control system regulates the motor speed alone over one portion of the load variation curve, and regulates the motor speed jointly with the inlet guide vane opening over another portion of the load variation curve, to achieve the most energy-efficient operating condition while avoiding the surge condition.  This optimum control path is realized by utilizing a signal which is a measure of the compressor head value.  Compressor surge or instability is avoided by deriving a critical Mach number (speed indication) for any given operating condition, as a function of the compressor head and vane position, and preventing the motor speed from going below that Mach number under the specific operating conditions. The control system of the invention is useful both with existing equipment, by way of retrofit, and with newly manufactured and installed equipment.
