In the preferred form the fluidic turbine control systems as applied to a Steam Turbine and extraction pressure to control turbine operation as a function of the extraction pressure and extraction pressure as a function of the turbine operation.

Abstract: An improved brake fluid reservoir is disclosed. The reservoir is made from polymethylpentene and includes 10-20% by weight glass fibers as an opacifying agent. A translucent reservoir is obtained which has the highly desirable feature of visibility of the fluid level in the reservoir without providing a clear view of the fluid.

Abstract: A discharge outlet coupling and guiderail assembly for a submersible pump has at least two spaced guiderails to which the submersible pump is slidably connected by means of a rail mounting bracket so that the submersible pump is movable up and down the guiderails parallel to the longitudinal axis thereof to permit the discharge outlet of the pump disposed remote from the guiderail mounting brackets to be oriented and aligned for engagement and disengagement with the flanged inlet end of a discharge elbow in the discharge line of the associated fluid pumping system to which the submersible pump must be operatively connected. Orientation of the pump, the respective spaced guiderails, and the discharge elbow is controlled by means of a common base plate to which the respective guiderails and the discharge elbow are connected in predetermined spaced relation.

Abstract: A valve having a plurality of movable, coaxially arranged annular plates is characterized by the use of fiber reinforced plate members having a thickness of greater than 0.2 inches and, in a preferred embodiment, a thickness to width ratio in excess of 0.5. A valve in accordance with the present invention is also characterized by the ratio of the number of biasing springs associated with each plate to the mean diameter of the plate being greater than 1.2 per inch.

Abstract: This improvement of a vehicle cab temperature control system for a cab having an operator enclosure with a roof and an outwardly exposed air filter attached to the roof includes a blower and a temperature control unit mounted within a duct which is secured to both the roof and to the air filter. The duct is spaced apart from the roof, thereby forming a chamber which receives controlled air from the temperature control unit. The flow of controlled air is produced by the blower as it moves the air through the air filter into the duct through its inlet aperture and then through the temperature control unit within the duct. The controlled air then exits the duct through either the duct's bleed aperture into the chamber or through the duct's outlet aperture into the operator enclosure.

Abstract: A boom assembly for a loader that is pivotally mounted on a tractor. The assembly includes a pair of boom arms which are pivotally connected at one end of the tractor. The arms are fabricated from two C-channels which are welded together. The arms have aligned inside apertures sized to accept a cross tie member which is rigidly connected to both channels.

The arms are fabricated from two C-channels which are welded together. The arms have aligned inside apertures sized to accept a tube which is rigidly connected to both channels. The assembly is completed when a cross tie member envelopes the tubes and is rigidly secured to the inner C-channels.

Abstract: The operational speed of a fluid drive unit in a hydromechanical transmission is limited by means of an overspeed preventing, one-way clutch establishing a positive drive connection between torque transmitting elements of the hydromechanical transmission. Two power paths are established between the planetary gear unit and the input shaft of the transmission to drive an output shaft at a variable drive ratio controlled by a variable displacement type of fluid drive unit. One of the power paths is established through fixed ratio gearing while the other power path is established through the fluid drive units while operating within a speed ratio range limited by the one-way clutch.

Abstract: A vehicle control mechanism for manipulating three controllable members through one control handle. The control mechanism includes a support rigidly attached to the vehicle. The support rotatably carries three control assemblies which are operably connected to one of each of the three controllable members. The control mechanism also includes a drive assembly rotatably carried by the first and third control assemblies first, second and third control assemblies and the support have force selectively transmitted therebetween by a roller which is contained in the control assembly by roller retainers of the support. The force which manipulates the controllable members is derived from the operator selectively pivoting the handle about the third control assembly. To manipulate the various control assemblies the operator will either pivot the handle to engage the handle and the dive assembly or pivot the handle to engage the handle and the second control assembly.

Abstract: A door latch mechanism for a tractor cab with a door having inside and outside wall and having one end pivotally attached to the cab. The mechanism includes a catch mounted on the door opposite the pivotal door attachment with the catch including a pivotally mounted engagement bias disengagement arm, an external handle mounted on the outside wall of the door between the latch and pivotal door attachment with the handle incorporating a pivotal activator for disengaging the catch while pivoting the door and a push lever driven by the activator to operate the catch, an internal handle mounted on the inside wall between the external handle and the catch for operating the catch from within the cab, and a rod assembly connecting the external handle, the catch, and the internal handle, with the rod assembly including a rod pivotally connected to the push lever and the catch and a one way lever connecting the rod and the internal handle.

Abstract: Grab handles positioned above and slightly in front of the operator's seat. The handles each having a major plane, which intercept behind the operator's seat. Each handle is secured to the roll-over protective structure or frame work of the cab.This is a continuation of application Ser. No. 507,039, filed Sept. 16, 1974, now abandoned.

Abstract: The addition of an air diverter to a tractor which has a partially enclosed engine, a shroud in arrangement for supplying cooling air to the engine and a carburetor operatively connected to the engine and mounted within the enclosure. The diverter separates a small portion of the cooling air from the main flow over the engine and uses this smaller flow to maintain an operable temperature for the carburetor.

Abstract: An adjustable fairlead roller system which uses a winch to pivotally vary the position of the fairlead roller assembly on a logging arch.

Abstract: A control system for controlling the engine governor on a tractor or like vehicle utilizing hand and foot throttles link-connected to the governor for control thereof without interaction between the throttles. Each throttle connects to the governor by separate linkage incorporating a flexible cable capable of transmitting tension but not a compression load enabling a tensioning of one cable through a manipulation of the associated throttle with the cable link of the second throttle going slack and transmitting no motion to the second throttle.

Abstract: A safety start system for lawn and garden equipment in which a single safety switch completes the starting circuit of the power source by responding to the disengaged condition of both the main clutch and the implement clutch of the machine. The starting circuit is completed in direct response to the operator's moving the implement clutch handle to its disengaged position thereby permitting a resilient actuating member to close a safety switch and complete the circuit. The circuit is interrupted upon his engagement of the main clutch through a release of the clutch pedal which changes the deflection point of the resilient actuating member from the safety switch to linkage which is connected to the clutch pedal mechanism.

Abstract: An adjustable fairlead roller system which uses a winch to pivotally vary the position of the fairlead roller assembly on a logging arch.

Abstract: A removal control system for a scraper having a tractor pivotally attached to a bowl, said bowl having a cutting blade attached thereto, an elevator pivotally mounted on said bowl, an engine and utilizing an elevator control system and a cutting depth control system either in combination or separately whereby the optimum removal rate is maintained during operation of said scraper.
